When the prestigious AAAS again promotes demagoguery and fallacies

Bad news! What a shame and pseudoscience by the American Association for the Advancement of Science (AAAS)!

Because of the global reduction in air pollution, now we have to reflect the "sun's radiation back to space"? What a nonsense!

"Global warming [???] is bad news for polar bears, seals, and walruses; the Arctic sheets of seasonal sea ice they frequent have been on the decline for decades.
An ambitious idea seeks to intervene: sea ice thickening [???], where engineers drill through the ice and pump up ocean water to freeze on top in an attempt to delay summertime melting. If successful, the extra ice would also make the poles brighter, reflecting more of the sun’s radiation back to space [???] and lessening a dangerous climate feedback loop.

Like all geoengineering ideas, it’s controversial. But field trials have begun, and the first results are out: while pumping thickens ice, those gains don’t stick around. ..."

"A simple idea [??] underpins an audacious intervention to augment Arctic sea ice and slow the climate feedback loop accelerating its disappearance. Drill holes through a floe, pump seawater onto its surface, and let the cold do the rest. The first results from two field tests show the technique can thicken the ice. But they also show those gains don’t last. ..."

France, Germany Propose ‘Symbolic’ EU Membership Path for Ukraine Without Voting Rights

Good news! About time!

"France and Germany are proposing a “symbolic” form of European Union integration for Ukraine that would grant limited benefits before full membership, according to a report by the Financial Times published on Monday, April 20.

The plan would allow Ukraine to participate in EU meetings but without voting rights and without immediate access to key parts of the bloc’s budget, including agricultural subsidies and regional funding.

Germany is advocating for an “associate membership” model, while France has suggested a similar concept described as “integrated state status,” both of which would delay full financial and political integration until Ukraine completes the standard accession process. ..."

Discovery could lead to new therapies for blood disorders

Good news!

"... investigators have revealed the detailed workings of a cell membrane protein that has essential roles in all animals. The discovery could lead to new therapeutic strategies for blood coagulation disorders, cancers and other conditions in which the protein, called a TMEM16 scramblase, works abnormally.

Scramblases operate within cell membranes, where they alter or “scramble” the normal layered arrangement of lipid molecules – an essential step in many biological processes. The scramblase TMEM16F also works as an ion channel, allowing small, charged molecules such as potassium or chloride ions through the membrane. ...

the researchers at last attained this goal by embedding the protein in liposomes – tiny lipid capsules – which allowed them to image its active and inactive structures at near-atomic-scale resolution. ...

TMEM16F’s rearrangement of cell membrane lipids enables platelet cells to clump together to make blood coagulate, and a mutation affecting the scramblase underlies Scott syndrome, a hemophilia-like bleeding disorder.
The protein is also involved in the formation of the placenta in pregnancy, bone development and immune functions; and it is exploited or suppressed in various cancers and infections. ..."

From the abstract:
"The ubiquitous transmembrane protein 16F (TMEM16F) Ca2+-activated channel and scramblase catalyzes phosphatidylserine externalization to enable blood coagulation, membrane fusion and brain immune surveillance.
Despite its importance, the molecular mechanisms underlying TMEM16F activation remain poorly understood.
Here, we obtained high-resolution cryo-electron microscopy structures of TMEM16F active in liposomes. In high-activity conditions, TMEM16F adopts two conformations, the canonical Ca2+-bound closed state and one where the upward rotation of the cytosolic domain leads to an X-shaped groove that forms a transmembrane pore and locally thins the membrane.
Using mutagenesis, functional assays and molecular dynamics simulations, we show that the X-shaped groove is active and mediates nonselective ion flux and lipid scrambling through distinct pathways; ions move within the protein-delimited pore, whereas lipids skirt the X-shaped groove.
Our findings provide a complete picture of TMEM16F Ca2+-dependent gating and demonstrate that imaging membrane proteins in a native-like environment can allow capturing otherwise inaccessible active states."

On Momentum Further Constrains Sharpness at the Edge of Stochastic Stability

This could be an interesting, but narrowly focused, new paper by Tomaso Poggio and his team!

Caveat: I have not read the paper (40 pages total) yet.

From the abstract:
"Recent work suggests that (stochastic) gradient descent self-organizes near an instability boundary, shaping both optimization and the solutions found.
Momentum and mini-batch gradients are widely used in practical deep learning optimization, but it remains unclear whether they operate in a comparable regime of instability.
We demonstrate that SGD with momentum exhibits an Edge of Stochastic Stability (EoSS)-like regime with batch-size-dependent behavior that cannot be explained by a single momentum-adjusted stability threshold.
Batch Sharpness (the expected directional mini-batch curvature) stabilizes in two distinct regimes:
at small batch sizes it converges to a lower plateau , reflecting amplification of stochastic fluctuations by momentum and favoring flatter regions than vanilla SGD; at large batch sizes it converges to a higher plateau , where momentum recovers its classical stabilizing effect and favors sharper regions consistent with full-batch dynamics.
We further show that this aligns with linear stability thresholds and discuss the implications for hyperparameter tuning and coupling."

[2604.14108] Momentum Further Constrains Sharpness at the Edge of Stochastic Stability

Born in Germany only 16 years after World War II ended

My whole life I wondered what was World War II, the Spanish Civil War and Caudillo Francisco Franco, fascist Italy and Benito Mussolini, the supremacist and warmongering Japanese Empire all about?

The leftist poet Bertolt Brecht (1898-1956) coined the phrase "An die Nachgeborenen" (To Those Born After) in 1939, which became "Die Last der Nachgeborenen" (The burden of those born after WWII) and the motto "Nie wieder" (never again). I sure can relate to this. It was probably my late father, a poet himself, who introduced me to Bertolt Brecht.

One of my late father's favorite poems, which he introduced me to and which I still remember, was written by the Romanian poet Paul Celan (1920-70, a Holocaust survivor) titled Todesfuge (published in 1948). The language of this poem is strange and amazing "„Schwarze Milch der Frühe wir trinken sie abends/wir trinken sie mittags und morgens wir trinken sie nachts/wir trinken und trinken/wir schaufeln ein Grab in den Lüften da liegt man nicht eng“ (the opening verses of this poem).

Why the Holocaust? Why the antisemitism? Therefore, I support Israel and Jews whenever I can! I strongly oppose Antisemitism all the time and in all its forms. All my life I made it my habit to learn more about the modern Israel and Ancient Judea and the intervening time period, the relationship between Arabs and Jews, the Levant and so on. Modern Israel (since 1948) is probably one of the most diverse and exciting countries in the world except perhaps for India. The history of Jews and Judaism is so fascinating (David & Goliath, Masada, Maccabee, King Solomon, Samson and Delilah and so much more). One of my late parents e.g. would teach me at a young age the meaning of the Judgement of King Solomon.

I was born in Frankfurt am Main and I grew up in the Westend district of the city.

From my late mother and my late father I was told a number of horrible stories about their and other children's war time experiences. My mother was about 6 years old when WWII ended, my father was about 12 years old. One of the stories, I remember was that my late father as a young boy once found a soldier's boot with a torn off leg still showing. What do e.g. the Ukrainian children go through since the Russo-Ukrainian War started in 2022?

When I was a child some of my German neighbors may have been Nazis and were possibly involved in atrocities against Jews. My late father pointed out several times that he suspected some of our German neighbors and other Germans were possibly perpetrators.

It was an open secret that some of the German perpetrators got away and were living among us. My paternal uncle had a typical German soldier tattoo (Waffen SS? I forgot where on the body (arm?) and what kind of tattoo it exactly was), which he was always hiding. Also, I do not remember whether and how he served in the German military etc. However, neither my late father nor I suspected he was involved in atrocities given e.g. what he told my father about his service in World War II and given his generally friendly and kind personality.

The Westend  Synagogue (see photo below) was located very near where I grew up. It was kind of sad to see that this large synagogue appeared to be in constant lockdown and it was always  fortified. This synagogue was not easily accessible to the public for security reasons.

While in high school, I had a Jewish high school buddy. We spent a lot of time together. He was not very athletic and looked perhaps a little bookish with his glasses, but he was a great guy. I also visited him several times at home and got to know his Jewish mother and father. They both were very nice! This family was not orthodox Jewish, but typical Jewish symbols were displayed in their home. If I remember correctly, his father was in the philately business, which is perhaps not so unusual for a Jew. In my youth, I was also a collector of stamps and coins from all over the world.

Then there was the Jewish leader Ignatz Bubis. He was often decried as a real estate speculator in Frankfurt (antisemitism?). However, he was also an active member of the Freie Demokratische Partei (FDP) in Frankfurt. My late father and I were active members as well of the FDP that is how I got to know Mr. Bubis.

As an older teenager I had the great opportunity to travel to Vienna in Austria for a summer vacation with a Jewish youth organisation from Frankfurt. It was a great experience and I had a great time. Here I was together with a group very nice people, mostly young Jews. I think, I had a crush on one of the very young Jewish women. It was there in the Viennese area that I discovered my lifelong love for real hazelnut spread. Unfortunately, I do not remember anymore how I was able to join this group and what the name of this group was. I believe, I have to thank my late father for this great experience.

The city of Frankfurt was heavily bombed during World War II due to the location of e.g. important companies of the chemical industry. Much of the city was in rubble. E.g. the opera house (die Alte Oper) in the center of Frankfurt was hallowed out, basically only the outer walls and some lower level structures in the interior were still standing. Many times I passed by these ruins, one day I even climbed into the ruins out of curiosity. The ruins of the opera house were left as a war memorial and reminder until it was rebuilt beginning in 1976  and reopened in 1981. The reconstruction was quite controversial at the time.

During my youth, there were numerous reports of unexploded ordnance, mostly WWII bombs discovered in the inner city of Frankfurt. Even at my neighborhood high school, which I had attended, there was a large bomb discovered in the corner of the school yard during some construction work. Me and a buddy of mine climbed on a close by, one story high car garage roof to watch the disposal team to take care of this bomb. Dangerous adventures.

The headquarters of the US Army V Corps was located until 1995 in the former IG Farben Hochhaus in the largest inner city park (Grüneburgpark) not far from where I grew up. Thus, I encountered many US soldiers during my childhood and beyond. It never crossed my mind that the American soldiers were an occupation force (as suggested by some Germans). Actually by frequently visiting two US military gyms (one was the V Corps main gym, the other was the 97th General Hospital gym) for several years, I learnt how to play basketball from black American soldiers. It was a very friendly, older black American gym attendant, who allowed/tolerated me to play basketball at the V corps gym. In the beginning, he jokingly reminded me not to wear those typical German skimpy shorts, but instead more American like trunks so his white American supervisor (an Irish guy who peeped on topless, sunbathing young German women while jogging in the Grüneburgpark during lunch break) would not complain. I have spent many weekends and evenings there to play ball. I enjoyed the contemporary soul, rap & funk music blasted across the gym or inside the barracks. Plus, I learnt some cool dance moves and I became a big fan of Soul Train hosted by Don Cornelius. I had a lot of fun with the mostly black American soldiers some of whom I came to know quite well. Sometimes we would also go out to discos together on Saturday evenings, I sometimes visited them in their barracks, or I joined barbecue parties with them etc. One of the older black American soldiers and basketball player also invited me over to his home for dinner with his wife and two children. I had a very good time. A few black American soldiers pointed out to me that I was naturally high, which I understood to be a compliment (no one had ever before told me that or ever since). I am not a churchgoer (other than as a tourist), but during this time I was somehow invited to attend a black American church service at a US military church near the small town of Hanau (not far from my home town Frankfurt). For me, the journey started from Frankfurt on a bus filled with black American churchgoers heading for this church. The church service with all the Gospel singing, expressions of joy and faith and so on was an incredible, mind blowing experience. Last, but not least, I have also witnessed a few cases of open, reverse racism of some black Americans against white Americans. Sometimes black Americans would call each other nigger, but a white American better not dare to say it.

Organ donations have surged in the United States, partly thanks to improved harvesting methods

Good news!

"Organ donations have surged in the United States, partly thanks to improved harvesting methods.

Until recently, most organs came from donors who were brain dead but kept on life support, with their circulatory systems still functioning.

Over the past decade, however, advances in organ preservation and recovery have made it increasingly feasible to recover organs after circulatory death [DCD], when the heart has stopped and preservation becomes far more difficult.

A recent study finds that in 2000, just 2 percent of donors fell into this category;
by 2025, that had risen to 49 percent, with the number of such donors rising from 118 to 8,129."

"... Recent innovations have facilitated recovery from medically complex DCD donors.
Normothermic regional perfusion, in which perfusion is restored in situ to limited organs after circulatory death, contributed to the rise in recovery of DCD organs since its use began increasing in 2019.
The regulatory approval of normothermic machine perfusion for livers (2021) contributed to the subsequent acceleration of DCD liver recovery, and normothermic machine perfusion enabled the advent of DCD heart transplantation in 2019.” "

"... By contrast, donation after circulatory death involves donors who do not meet criteria for brain death and who cannot be kept alive without life support machines. In these cases, if the family chooses to stop life support, it is then given the option to do so in an operating room instead of the intensive care unit.
If the patient dies within a set time after support is removed, organs can be recovered and used for transplantation, preserving the opportunity to donate according to the wishes of the family and the patient. ...
"

From the abstract:
"Organ transplant improves survival and quality of life, but transplant access is limited by organ shortages.
Transplants in the US predominantly use deceased donor organs, including 75% and 94% of kidney and liver transplants, respectively, and all lung, heart, and pancreas transplants from 2018 to 2025. Improving transplant access therefore relies on expanding the deceased donor pool, including by increasing donation after circulatory death (DCD), in which organs are recovered from donors with irreversible loss of circulatory function.
Factors limiting DCD use include a higher risk of organ dysfunction compared with donation after brain death organs and the increased complexity of DCD organ recovery, which is not possible if the time between life support withdrawal and circulatory death is prolonged. Despite these limitations, the severe organ shortage combined with technological innovations that enhance DCD organ function have increased interest in DCD organ transplant by transplant programs and organ procurement organizations (OPOs), the federal contractors responsible for coordinating US organ recovery and allocation. This study aimed to describe secular trends in DCD donation."

The Ancient Weapons Active in Your Immune System Today

Recommendable!

Caveat: I did not read the entire, long article!

"... In recent years researchers have come upon a surprising finding: Some of the machinery that bacteria use to defend against phages exists, almost unchanged, in our own cells. According to dozens of discoveries made over the past decade, the rules of engagement between cells and viruses were written billions of years ago and still largely define how our innate immune system, the first responder to infection, defends us against viruses and bacteria today. ...

Two recent waves of discovery broke this field open.
First, in 2018, researchers reported a variety of novel bacterial defense systems against viruses(opens a new tab), which now number in the hundreds.
The second wave, starting around 2019, showed that some of these bacterial mechanisms exist in plant and animal cells, including our own — and that they still work the same way they did in those distant ancestors. ...

These and other discoveries that followed reveal an unexplored landscape of human innate immunity — one that could lead to new medical treatments and biotechnological tools ...

A few years later, ... team observed that big constellations of immune genes, including restriction-modification enzymes and CRISPR arrays, tended to cluster together in the same region of bacterial genomes. He and other labs observed that genes of unknown function within these “defense islands” or “genomic islands” could potentially represent novel anti-phage mechanisms. ...

In 2018, his team showed that many of the unknown genes in these defense islands did, in fact, function as a variety of anti-phage defense systems. ..."

A nasal spray reversed brain aging and inflammation in just two doses

Good news! This could be a breakthrough!

"A nasal spray reversed brain aging and inflammation in just two doses, restoring memory and cognitive sharpness, in a Texas A&M study of mice that researchers say could reshape treatment for dementia."

"Summary: For decades, “neuroinflammaging”, the slow-burning inflammation that causes brain fog and memory decline, was considered an unavoidable part of getting older. However, a landmark study suggests the clock can be turned back.

Researchers developed a non-invasive nasal spray that uses microscopic “delivery parcels” to travel directly into the brain. With just two doses, the therapy dramatically reduced chronic inflammation, recharged cellular “power plants” (mitochondria), and restored memory and cognitive sharpness in aging models.

Key Facts

  • Rapid & Lasting Results: Significant cognitive improvements were observed within weeks and, remarkably, persisted for months after only two doses.
  • Universal Efficacy: Unlike many medical studies that show varying results by sex, this therapy proved equally effective in both males and females.
  • Behavioral Recovery: Treated models showed a restored ability to recognize familiar objects and adapt to changes in their environment—key indicators of a healthy, functioning memory center.
..."

From the abstract:
"Neuroinflammaging, a moderate, chronic, and sterile inflammation in the hippocampus, contributes to age-related cognitive decline.
Neuroinflammaging comprises the activation of the nucleotide-binding domain, leucine-rich repeat family, and pyrin domain-containing 3 (NLRP3) inflammasomes, and the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway that triggers type 1 interferon (IFN-1) signalling.
Studies have shown that extracellular vesicles from human induced pluripotent stem cell-derived neural stem cells (hiPSC-NSC-EVs) contain therapeutic miRNAs that can alleviate neuroinflammation.
Therefore, this study examined the effects of late middle-aged (18-month-old) male and female C57BL6/J mice receiving two intranasal doses of hiPSC-NSC-EVs on neuroinflammaging in the hippocampus at 20.5 months of age. Compared with animals receiving vehicle treatment, the hippocampus of animals receiving hiPSC-NSC-EVs exhibited reductions in astrocyte hypertrophy, microglial clusters, and oxidative stress, along with elevated expression of antioxidant proteins and genes that maintain mitochondrial respiratory chain integrity.
Moreover, hiPSC-NSC-EVs therapy decreased the levels of various proteins involved in the activation of the NLRP3 inflammasome, p38/mitogen-activated protein kinase, cGAS-STING-IFN-1, and Janus kinase and signal transducer and activator of transcription signalling pathways.
Furthermore, in vitro assays using genetically engineered RAW cells and hiPSC-NSC-EVs, with or without targeted depletion of specific miRNAs, demonstrated that miRNA-30e-3p and miRNA-181a-5p, both present in hiPSC-NSC-EVs, can significantly inhibit the activation of the NLRP3 inflammasome and the STING pathway, respectively. Additionally, single-cell RNA sequencing conducted 7 days post-treatment revealed that hiPSC-NSC-EVs induce widespread transcriptomic changes in microglia, including increased expression of numerous genes that enhance oxidative phosphorylation and reduced expression of abundant genes that drive multiple proinflammatory signalling pathways.
These changes mediated by hiPSC-NSC-EVs were also associated with improved cognitive and memory function.
Thus, intranasal hiPSC-NSC-EVs therapy in late middle age can effectively diminish proinflammatory microglial transcriptome and signalling cascades that drive neuroinflammaging in the hippocampus, contributing to better brain function in old age."

The case for a new economic theory of how markets really work without the Invisible Hand. Really!

Food for thought! However, I am not getting smart out of the abstract of this research article. It sounds like gibberish to me!

Is it possible that the authors here wrongly connected market clearing with the Invisible Hand? I bet!

Service economy is not a new concept! It has been around for several decades. So what is new here? Well, manufacturing is still very much alive and kicking too, because humans can not live by services alone, products are still needed.

"... In the real world, it is rare that markets “clear”—meaning that all the products reach customers thanks to the balancing of the invisible hand. Businesses must often commit to what they will charge and how much they will produce before they know what the actual demand will look like. 

A Model for the Service Economy

While traditional economic theories were built in an era of manufacturing, this research is particularly descriptive of the modern service industry [???], which now dominates the U.S. economy. ..."

From the abstract:
"Modern theories of the business cycle do not allow for the simultaneous rational choice of both prices and quantities, instead assuming that an “invisible hand” determines one of these variables to clear markets.
In this paper, we develop a macroeconomic framework in which both prices and quantities are chosen directly by firms, and exchange is both voluntary and efficient. Because of uncertainty about demand and productivity, individual product markets can be in excess supply or rationed.
The absence of market-clearing changes pricing and production in qualitatively important ways: markups are no longer determined solely by the elasticity of demand, and higher uncertainty reduces production and increases markups.
In equilibrium, production in rationed markets has a negative aggregate demand externality on demand in slack markets.
Differently from New Keynesian economies, monetary shocks propagate by reducing economic slack, raising aggregate labor productivity and consumption, while uncertainty shocks act as stagflationary cost-push shocks. We integrate our theory of disequilibrium in a dynamic, rational-expectations “New Old Keynesian Model” and demonstrate its implications for the business cycle."

Solid-state quantum sensors can measure several properties at once

Amazing stuff! This could be a breakthrough!

"A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using classical sensors alone. Such quantum sensors are currently being used to study the inner workings of cells and the outer depths of our universe.

Particularly promising are solid-state quantum sensors, which can operate at room temperature. Unfortunately, most solid-state quantum sensors today only measure one physical quantity at a time — such as the magnetic field, temperature, or strain in a material. Trying to measure both the magnetic field and temperature of a material at the same time causes their signals to get mixed up and measurements to become unreliable.

Now, ... researchers have created a way to simultaneously measure multiple physical quantities with a solid-state quantum sensor. They achieved this by exploiting entanglement, where particles become correlated into a single quantum state. In a new paper, the team demonstrated its approach in a commonly used quantum sensor at room temperature, measuring the amplitude, frequency, and phase of a microwave field in a single measurement. They also showed the approach works better than sequentially measuring each property or using traditional sensors.

The researchers say the approach could enable quantum sensors that can deepen our understanding of the behavior of atoms and electrons inside materials and living systems like cancer cells. ...

Although the researchers say their sensor didn’t measure each quantity at the highest possible precision, in future work they plan to explore if their approach can achieve higher precision for each parameter. ..."

From the abstract:
"Quantum multiparameter estimation promises to extend quantum advantage to the simultaneous high-precision measurements of multiple physical quantities. However, realizing this capability in practical quantum sensors under realistic conditions remains challenging due to intrinsic system imperfections.
Here, we experimentally demonstrate multiparameter estimation using a nitrogen-vacancy (NV) center in diamond, a widely adopted solid-state quantum sensor.
Leveraging electronic-nuclear spin entanglement and optimized Bell-state measurement at room temperature, we simultaneously estimate the amplitude, detuning, and phase of a microwave drive from a single measurement sequence.
Despite practical constraints, our results achieve linear sensitivity scaling for all parameters with respect to interrogation time. This work bridges the gap between foundational quantum estimation theory and real-world quantum sensing, opening pathways toward enhanced multiparameter quantum sensors suitable for diverse scientific and technological applications."

Hisbollah in Deutschland: Wie Europas wichtigster Finanzstandort für den Terror wachsen konnte

Neues aus der Bananenrepublik D! Oder ist das eine neue Form von Antisemitismus?

"Deutschland taucht darin als Hauptstandort der Finanzgeschäfte der Hisbollah in Europa auf.

Das ist keine Randnotiz aus dem Nahen Osten – das ist ein Befund über die Bundesrepublik. Während Politiker in Berlin bei jeder Gelegenheit mit moralischer Entschlossenheit posieren, lief hier laut der neuen Analyse ein Knotenpunkt für die Finanzierung einer vom Iran gestützten Terrororganisation.
Die Studie beschreibt Verbindungen zu global tätigen Unternehmen und ein Geflecht aus legalen und illegalen Geschäftsmodellen. Sie nennt ausdrücklich Drogenhandel, Kunsthandel, Blutdiamanten, Ölschmuggel, Geldwäsche und inzwischen auch Kryptowährungen als Teil der Finanzarchitektur. Wer da noch von vereinzelten Sympathisanten spricht, betreibt Beruhigungsrhetorik für Schlafwandler.

Der Kern des Skandals liegt tiefer. Die Europäische Union hat sich jahrelang in die bequeme Fiktion geflüchtet, bei der Hisbollah lasse sich ein angeblich politischer Teil von einem militärischen Teil trennen. Genau diese Aufspaltung beschreibt die neue Studie als Einfallstor. ...

Deutschland hat die gesamte Hisbollah zwar bereits im April 2020 verboten. Das Bundesinnenministerium sprach damals ausdrücklich ein Betätigungsverbot gegen die Terrororganisation aus. Der neue Befund fällt dadurch noch verheerender aus. Ein Verbot auf dem Papier hat den Standort Deutschland offenkundig nicht aus der Gleichung entfernt. Es zeigt nur, wie groß die Lücke zwischen Verlautbarung und Wirkung geblieben ist. Der Apparat verkündet Härte, während sich Netzwerke anpassen, umetikettieren und über Wirtschaftsstrukturen weiterarbeiten. Gut, dass man den Fokus voll auf Rollator-Gangs und politische Schauprozesse verlegt hat. ...

Der Vorgang ist politisch vernichtend. Wer Europa mit immer neuen Kontrollen gegen den eigenen Bürger überzieht, jede digitale Regung misstrauisch beäugt und unter Kontrolle stellen will, sollte doch wohl wenigstens irgendwie versuchen zu verhindern, dass eine vom Iran gefütterte Terrororganisation auf europäischem Boden ihre Finanzadern pflegt. ..."

On GIANTS: Generative Insight Anticipation from Scientific Literature

How will machine learning & AI revolutionize scientific research? Here is an example, the latest research paper by Chelsea Finn and Noah D. Goodman.

Caveat: I have not yet read this paper.

From the abstract:
"Scientific breakthroughs often emerge from synthesizing prior ideas into novel contributions.
While language models (LMs) show promise in scientific discovery, their ability to perform this targeted, literature-grounded synthesis remains underexplored.
We introduce insight anticipation, a generation task in which a model predicts a downstream paper's core insight from its foundational parent papers.
To evaluate this capability, we develop GiantsBench, a benchmark of 17k examples across eight scientific domains, where each example consists of a set of parent papers paired with the core insight of a downstream paper.
We evaluate models using an LM judge that scores similarity between generated and ground-truth insights, and show that these similarity scores correlate with expert human ratings.
Finally, we present GIANTS-4B, an LM trained via reinforcement learning (RL) to optimize insight anticipation using these similarity scores as a proxy reward. Despite its smaller open-source architecture, GIANTS-4B outperforms proprietary baselines and generalizes to unseen domains, achieving a 34% relative improvement in similarity score over gemini-3-pro.
Human evaluations further show that GIANTS-4B produces insights that are more conceptually clear than those of the base model.
In addition, SciJudge-30B, a third-party model trained to compare research abstracts by likely citation impact, predicts that insights generated by GIANTS-4B are more likely to lead to higher citations, preferring them over the base model in 68% of pairwise comparisons. We release our code, benchmark, and model to support future research in automated scientific discovery."

Scientists stunned by ‘fundamentally new way’ life produces DNA

Amazing stuff! 

However this is junk journalism by AAAS! No link to the research article! No title of the research article provided!

"For decades, biology textbooks have enshrined a simple rule: DNA is made by copying a template. After one enzyme unzips a DNA double helix into separate strands, another called a polymerase builds a complementary sequence, base by base, for each strand. Presto: two copies of the original DNA. But new research into how bacteria defend themselves from viruses now shows this synthesis rule isn’t absolute. Today in Science, a Stanford University team describes a bacterial enzyme that synthesizes DNA without a nucleic acid template, using its own structure as a guide. ...

The use of a protein as a template for DNA synthesis, ... “is a meaningful conceptual shift from the classical central dogma,” in which information flows in one direction from nucleic acids like DNA to protein. Scientists hope the novel form of DNA synthesis can be adapted as a tool for basic biological research, much like the powerful genome editor CRISPR was developed from another bacterial defense system. ...

The new finding centers on DRT3, a defense system that protects bacteria from viruses, known as phages, that infect them. DRT3, the researchers found, bypasses the logic of base pairing. It relies on two reverse transcriptases: a conventional one that builds single-stranded DNA from an RNA template, and a second, unusual one that assembles its complement from its own built-in template. This unusual enzyme, called Drt3b, has amino acids in its active site that mimic a template RNA strand. ..."

From the abstract:
"Defense-associated reverse transcriptases (DRTs) are widespread bacterial anti-phage systems that use unconventional mechanisms of polynucleotide synthesis. We show that DRT3, which comprises two distinct RTs (Drt3a and Drt3b) and a noncoding RNA (ncRNA), synthesizes alternating poly(GT/AC) double-stranded DNA.
Cryo–electron microscopy structures at 2.6 Å resolution reveal a D3-symmetric 6:6:6 complex of Drt3a, Drt3b, and ncRNA. Drt3a produces the poly(GT) strand using a conserved ACACAC template within the ncRNA.
Notably, Drt3b synthesizes a complementary, protein-primed poly(AC) strand in the complete absence of a nucleic acid template, using conserved active site residues specific to Drt3b to enforce precise base alternation. These findings expand the functional landscape of nucleic acid polymerases, revealing a protein-templated mechanism for sequence-specific DNA synthesis."

Israel Blocks France’s Participation in its Peace Talks With Lebanon

Probably a good move by Israel! President Macron is dubious or even duplicitous!

Lebanon is perhaps to some extent Francophone, but that does not provide sufficient excuse for President Macron to get involved.

"... For under Macron, France has become even more hostile to Israel than it was before his ascendance to the presidency. ...

Macron never condemned Hezbollah for its missile and drone fire into Israel, though he was quick to deplore Israel’s retaliatory attacks on Hezbollah targets in south Beirut. ...

Macron prevented American military planes delivering weapons to Israel to use its airspace. ..."

Jake Sullivan: The Tech High Ground. Really!

What a moron! He was the National Security Advisor for the senile, demented and pathological liar, the 46th President!

"“For decades, U.S. policy toward China rested on a quiet but powerful assumption: Beijing was essentially running the same race as the United States, just a few steps behind,” writes Jake Sullivan, former U.S. national security adviser, in a new essay from the forthcoming issue of Foreign Affairs. As technology—from semiconductors to artificial intelligence, biotechnology to clean energy—becomes “the central front in U.S.-Chinese competition,” Washington may not have the durable lead [???] it thought it had.

The United States’ biggest rival is starting to dominate “many of the foundational layers that underpin the modern economy,” Sullivan argues. Regaining these areas of high ground [???] “must be the central task of American statecraft [???] in the twenty-first century.” After all, “technological power is translating directly and rapidly into geopolitical power to a degree the world hasn’t seen in years.”"

Growing engineered liver tissue on demand directly in the body

Good news!

"... “We asked if it would be possible to first implant a small-scale liver construct and then drive it to expand in the body following its engraftment. A sufficiently grown, functional ‘satellite liver’ could immediately relieve the metabolic burden in a damaged liver and help bridge the time until a transplant becomes available,”  ..."

From the abstract:
"Despite the promise of engineered tissue implants for the treatment of organ failure, scaling of these constructs to sizes of therapeutic relevance remains a barrier to clinical translation.
Here, we propose a strategy to circumvent this limitation: to instead implant a small-scale construct and then induce it to grow in situ after its engraftment into a host.
Using engineered liver tissue as a proof-of-concept application, we integrated synthetic biology and tissue engineering tools to build liver tissues that can be expanded on-demand after implantation in vivo.
To achieve this goal, we first identified the combination of Yes-associated protein (YAP) and growth factor (GF) signaling as sufficient to drive human hepatocyte proliferation in dense, three-dimensional engineered tissues.
We then engineered control of these signaling axes using synthetic biology tools to drive human liver tissue expansion both in vitro and in vivo.
As such, this work establishes a genetic strategy for generating large organ implants through bioengineered on-demand outgrowth via synthetic biology triggering (BOOST)."

Growing liver tissue on demand directly in the body "New study combines tissue engineering with synthetic biology tools to grow healthy liver tissue inside the body, and lays foundation for “smart” solid organ therapies"

Fig. 1. GF and YAP signaling synergize to induce proliferation of dense cultures of HEPs.



The genetic “BOOST” strategy, explained in his graphic, integrates tissue engineering and synthetic biology tools to enable on-demand liver growth inside the body. By specifically rewiring the gene expression of primary liver hepatocytes and supportive fibroblast cells, a tissue growth program is switched on in a small, engineered liver construct after its implantation into recipients and upon addition of an inducing agent (shown as a pill). As a result, the hepatocytes in the construct start and continue to proliferate until a desired construct size has been reached and the inducing signal is not provided anymore. In mice, BOOST resulted in robust and healthy liver growth.


Study reveals a new role for cell membranes

Amazing stuff!

"Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do more than simply provide protection — they also influence the behavior of the protein receptors embedded in them.

A new study ... adds further support to that idea. The researchers found that changing the composition of the cell membrane can alter the function of a membrane receptor that promotes proliferation.

Epidermal growth factor receptor (EGFR) can be locked into an overactive state when the cell membrane has a higher than normal concentration of negatively charged lipids, the researchers found. This may help to explain why cancer cells with high levels of those lipids enter a highly proliferative state that allows them to divide uncontrollably. ..."

From the eLife assessment and abstract:
"eLife Assessment
The authors describe an interesting approach to studying the dynamics and function of membrane proteins in different lipid environments. The fundamental findings have theoretical and practical implications beyond the study of EGFR to all membrane signalling proteins. The evidence supporting the conclusions is compelling, based on the use of a nanodisk system to study membrane proteins in vitro, combined with state-of-the-art single-molecule FRET. The work will be of broad interest to cell biologists and biochemists.

Abstract
Cell surface receptors transmit information across the plasma membrane to connect the extracellular environment to intracellular function. While the structures and interactions of the receptors have been long established as mediators of signaling, increasing evidence suggests that the membrane itself plays an active role in both suppressing and enhancing signaling. Identifying and investigating this contribution has been challenging owing to the complex composition of the plasma membrane.
We used cell-free expression to incorporate the epidermal growth factor receptor (EGFR) into nanodiscs with defined membrane compositions and characterized ligand-induced transmembrane conformational response and interactions with signaling partners using single-molecule and ensemble fluorescence assays. We observed that both the transmembrane conformational response and interactions with signaling partners are strongly lipid dependent, consistent with previous observations of electrostatic interactions between the anionic lipids and conserved basic residues near the membrane adjacent domain.
Strikingly, the active conformation of EGFR and high levels of ATP binding were maintained regardless of ligand binding with high anionic lipid content typical of cancer cells, where EGFR signaling is enhanced.
In contrast, the conformational response was suppressed in the presence of cholesterol, providing a mechanism for its known inhibitory effect on EGFR signaling.
Our findings introduce a model of EGFR signaling in which the lipid environment can override ligand control, providing a biophysical basis for both robust EGFR activity in healthy cells and aberrant activity under pathological conditions. The membrane-adjacent protein sequence, likely responsible for the lipid dependence, is conserved among receptor tyrosine kinases, suggesting that active regulation by the plasma membrane may be a general feature of this important class of proteins."
