Bursting bubbles break down PFAS

Good news! Human ingenuity can handle PFAS anytime!

The daily alarmism and hysteria about the so called forever chemicals like PFAS is totally over the top and reminds of superstition!

How dangerous are these pollutants really except that they are called forever chemicals? A case of demagoguery?

"The sea-dwelling mantis shrimp strikes its prey with enough force that even if it misses, it creates bubbles of gas that rapidly collapse, sending shockwaves that can stun or kill.

Mantisonix – a spin-out from the University of Surrey, UK – is using a similar technique to break down persistent fluorochemicals with high-frequency sound waves. ..."

Repurposing used jet engines into natural gas turbines

Good news! Almost like the Biblical "Swords to plowshares"!

Human ingenuity at its best!

"US companies are trying to repurpose jet engines into natural gas turbines to power data centers. According to a Jefferies analyst, about 1,600 commercial jet engines are retired each year, and if a third were converted, they could yield roughly 13 gigawatts of generating capacity."

Early neanderthals made fire 400,000 years ago in the UK pushing back the origin of human fire making by over 350,000 years

Amazing stuff! Another surprising discovery about the Neanderthals!

I had previously blogged here already about this discovery, but it was only about a video!

I bet this is not the earliest ever, but other places somewhere around the world will be discovered in the future.

"... Pinpointing exactly when this kind of fire use evolved is tricky, since the traces of natural burns and human-made ones look alike. Now, a new study reports on a concentrated patch of heated sediment and burned stone tools from the East Farm Barnham archeological site.

The researchers found two fragments of pyrite, a mineral that can produce sparks when struck against flint, indicating that the early Neanderthals used them as “a fire-making kit.” These ancient deposits mark the earliest known evidence of fire-making, roughly 400,000 years ago. ..."

"A stunning discovery at an archaeological dig in the UK is rewriting the timeline of when humans first made fire.

Researchers have discovered the earliest known instance of human-created fire, which took place in the east of England 400,000 years ago.

The new discovery, in the village of Barnham, pushes the origin of human fire-making back by more than 350,000 years, far earlier than previously thought. ..."

"The discovery shows humans were making fire around 350,000 years earlier than previously known.

Research ... provides evidence of the earliest known instance of fire-making by humans – around 400,000 years ago. Previous recorded instances of fire-making date to only 50,000 years ago. ..."

From the abstract:
"Fire-making is a uniquely human innovation that stands apart from other complex behaviours such as tool production, symbolic culture and social communication.
Controlled fire use provided adaptive opportunities that had profound effects on human evolution. Benefits included warmth, protection from predators, cooking and creation of illuminated spaces that became focal points for social interaction. Fire use developed over a million years, progressing from harvesting natural fire to maintaining and ultimately making fire.
However, determining when and how fire use evolved is challenging because natural and anthropogenic burning are hard to distinguish. Although geochemical methods have improved interpretations of heated deposits, unequivocal evidence of deliberate fire-making has remained elusive.
Here we present evidence of fire-making on a 400,000-year-old buried land surface at Barnham (UK), where heated sediments and fire-cracked flint handaxes were found alongside two fragments of iron pyrite—a mineral used in later periods to strike sparks with flint.
Geological studies show that pyrite is locally rare, suggesting it was brought deliberately to the site for fire-making.
The emergence of this technological capability provided important social and adaptive benefits, including the ability to cook food on demand—particularly meat—thereby enhancing digestibility and energy availability, which may have been crucial for hominin brain evolution."

"... Sites in Africa suggest humans used natural fire over a million years ago, but the discovery at the Palaeolithic site in Barnham evidences the creation and control of fire, which carries huge implications for human development and evolution. Until now, the oldest known evidence of fire-making was from 50,000 years ago, found in northern France. ..."

Light-driven catalyst can break down PFAS forever chemicals

Good news!

Remember so called "forever chemicals" is mostly alarmism, hysteria, and demagoguery! Unfortunately, too many scientists engage in this nonsense too!

Alert: Plastophobia is a serious disorder. Please seek immediate medical help! (Caution: satire)

What about all the benefits of plastics in our lives? What are the possible substitutes (how healthy are the substitutes)?


"But their ongoing impact on health issues in humans and other animals is being uncovered. Some PFAS are carcinogenic. The new research ... describes how a material can use light to catalyse a reaction which breaks down a range of pollutants in water including PFAS. This kind of approach has previously shown promise in breaking down PFAS. ..."


"... The process involves the use of a class of materials known as covalent organic frameworks, or COFs, whose porous structure ⎯ and hence high surface area ⎯ make them useful in light-driven, or photocatalytic, reactions. When they interact with light, some of the electrons in COF molecules get displaced, forming holes, and this bifurcation of charges is what makes COFs good photocatalysts. ..."


From the abstract:

"Nature-inspired photocatalysis provides a sustainable solution for energy conversion and pollutant degradation. Covalent organic frameworks (COFs), with tunable properties and high porosity, have shown promise as photocatalysts, though their synthesis often requires extensive efforts. In this study, we report the in-situ growth of COFs on defective hexagonal boron nitride (hBN) surfaces to form hBN@1,3,5-triformylphloroglucinol (Tp)-4,4′-diamino-[1,1′-biphenyl]-3,3′-dicarbonitrile (DBCN) heterostructures. Bandgap analysis and ultraviolet photoelectron spectroscopy revealed the formation of type-II heterojunctions, enhancing charge separation and minimizing recombination. Density functional theory simulations confirmed efficient charge transfer at the COF-hBN interface. The hBN@Tp-DBCN heterostructures demonstrated remarkable versatility, achieving nearly complete degradation of dyes, pharmaceutical waste, and persistent compounds such as perfluorooctanoic acid [PFAS]. Practical implementation in vertical and horizontal configurations further validated their application potential. This research underscores the efficacy of hBN@COFs heterostructures in photocatalysis and offers a promising direction for metal-free heterostructures in artificial photosynthesis and water treatment."

Beer yeast waste spun into a promising sustainable yarn 50% stronger than wool and sold as "zero hunger"

I toast to that! Let's have another round of beer please! 😊 Or is this a case of being drunken with environmental virtue signalling?

I have my doubts whether this is cost effective and competitive.

Invented by students of the Pennsylvania State University. How many beers did they have before the light bulb went on?

"Yeast waste from breweries have been spun into textile fibres at a cost that could be affordable for clothing. A group in the US has reported that the fermented yeast proteins can be extracted and spun into a fibre stronger than wool. ...

at Pennsylvania State University, and his group have created an enzymatic process that breaks down cell walls in brewer’s yeast (Saccharomyces cerevisiae) and converts the released proteins into insoluble aggregates. It taps a commercial enzyme mix used in food processing. ...

After the enzyme treatment, the protein pulp was dissolved, along with cellulose, in the aqueous organic solvent, N-methyl morpholine N-oxide. This is used in the industrial lyocell process that converts forestry pulp into fibres for more sustainable textiles. ..."

From the significance and abstract:
"Significance
Zero Hunger [???] requires innovative solutions that address the intricate relationships between food, water, and land use. One promising approach is to replace plant-based fibers, such as cotton, with fermentation-based fibers. By leveraging biomanufacturing, we can produce sustainable, high-performance fibers that do not compete with food crops for land, water, or nutrients. This shift would free up arable land for food production, enhance crop yields, and promote more efficient use of water resources. Moreover, fermentation-based fibers offer a reduced environmental footprint, lowering greenhouse gas emissions and mitigating the impact of textile production on ecosystems. By embracing biomanufacturing, we can make significant strides toward achieving the “Zero Hunger” goal, ensuring everyone can access nutritious food while promoting sustainable development goals.

Abstract
Biomanufactured fibers produced through fermentation processes provide a promising pathway to decouple textile production from agricultural land. This would free up arable land for food cultivation and contribute to the United Nations Sustainable Development Goal 2: Zero Hunger [???].
Protein fibers from natural sources such as cocoon silk, collagen, and soy have attracted attention since the last century. However, commercial production declined with the rise of cheaper synthetic fibers and competition for food crops. Recently, renewed interest in protein fibers has emerged as a means to minimize plastic pollution, fueled by advances in fermentation, even though challenges related to yield, costs, and industrial spinning persist.
Here, we studied a lyocell-based technique for spinning protein fibers using yeast biomass purified through an enzymatic method. We demonstrated that the enzymatic approach produces insoluble proteins that can be continuously spun for over 100 h of production time.
Pilot-scale production exhibited stable spinning behavior with high viscosity and consistency quality. We achieved fiber fineness between 1.7 and 2.2 dtex, with strength values reaching 23 cN/tex, which is 50% higher than those of natural protein fibers such as wool.
Life cycle assessment indicates that fermentation-based protein fibers require significantly less land and water [???] than natural fibers while providing a reduced environmental footprint.
Techno-economic analysis indicates a cost of $6 per kilogram at a production rate of 6,750 t annually. Adopting biomanufacturing-based protein fibers marks a significant advancement toward a future where fiber needs are fulfilled without compromising the planet’s capacity to nourish its growing population."

Fake microscopy images generated by AI are indistinguishable from the real thing

Bad news? What is real and what is fake? I guess, human ingenuity will take care of this issue eventually!

"A new nanoscience paper describes an exciting new material that closely resembles a much-loved puffed corn snack. A scatter of twisted tubes, dubbed nano-cheetos, are shown in a clear electron microscopy image. The only problem: the material isn’t real. The image was made with ChatGPT, by a team of materials scientists who warn that such AI-generated images could make scientific fraud near-undetectable. ..."

"... The piece draws attention to a concerning new reality: even experienced researchers are increasingly unable to distinguish authentic nanomaterial microscopy images from AI-generated forgeries. This blurring of truth and fabrication raises profound concerns for the integrity of scientific publishing, peer review, and public trust in nanoscience. ..."

"Generative AI has made it trivial to generate fake microscopy images that are indistinguishable from real images, even for experts. As researchers in nanoscience, it is time for us to face this reality and discuss strategies to conserve the integrity of our discipline."

An increase in rocket launches would harm the ozone layer. Really!

Ever since the widening ozone layer hole was first discovered in 1985, the ozone layer is another favorite when it comes to alarmism and hysteria.

As usual, this alarmism and hysteria is based on (flawed) computer model simulations or in other words, this research is speculative if not junk! Human ingenuity can easily handle the ozone layer!

There is probably little doubt that e.g. satellite launches will increase in coming years. 

From the abstract:
"Rocket emissions thin the stratospheric ozone layer. To understand if significant ozone losses could [???] occur as the launch industry grows, we examine two scenarios [???]. 
Our ‘ambitious’ scenario (2040 launches/year) yields a −0.29% depletion in annual-mean, near-global total column ozone in 2030. Antarctic springtime ozone decreases by 3.9%.
Our ‘conservative’ scenario (884 launches/year) yields −0.17% annual, near-global depletion; current licensing rates suggest this scenario may be exceeded before 2030.
Ozone losses are driven by the chlorine produced from solid rocket motor propellant, and black carbon which is emitted from most propellants. The ozone layer is slowly healing from the effects of CFCs, yet global-mean ozone abundances are still 2% lower than measured prior to the onset of CFC-induced ozone depletion.
Our results demonstrate that ongoing and frequent rocket launches could [???] delay ozone recovery. Action is needed now to ensure that future growth of the launch industry and ozone protection are mutually sustainable."

The Swiss pharmaceutical company Roche to begin phase III trial on a new antibiotic to combat one of the world’s deadliest drug-resistant infections.

Good news! Human ingenuity beats any bacteria!

"The drug [zosurabalpin} targets Acinetobacter baumannii, a hospital-acquired superbug resistant to nearly all existing antibiotics. Roche plans to begin Phase III trials in late 2025—a rare late‑stage advance in a field long stalled by limited commercial incentives."

"... Zosurabalpin is a tethered macrocyclic peptide (MCP) antibiotic that was identified through the screening of nearly 45,000 compounds. As described in two papers published in Nature in January 2024 by scientists at Roche and Harvard University, MCPs work by blocking the transport of lipopolysaccharide from the inner bacterial membrane to the outer membrane, which is essential for outer membrane formation and antibiotic resistance in A baumannii. ..."

What about hydrogen power as a future source of energy?

Many charlatans/demagogues want to indoctrinate the public on the narrative of so called "clean energy" and "water vapor".

Potentially, huge quantities of hydrogen gas could be produced by splitting water (from the oceans) using electricity from solar panels.

However, there are some serious considerations and technical/engineering challenges:

  1. How to store large amounts of hydrogen? The volumetric energy density is low, which means e.g. more storage is needed.
    How much energy will be needed to compress hydrogen or to maintain the storage?
  2. Are there better ways to produce hydrogen than splitting water with electricity?
  3. At large, global scale, how will we deal with all the water vapor and the oxygen generated by splitting water?
  4. Hydrogen is a very hazardous gas. Remember the Hindenburg Disaster of 1937!
  5. How do we mass transport hydrogen gas e.g. from producer to user?
I am very confident, we can find solutions to these issues thanks to human ingenuity

However, e.g. currently way too much money is wasted on environmentally harmful and intermittent wind power and solar power instead of focusing it on e.g. nuclear fusion, superconductivity, and hydrogen power.

A new catalyst can turn methane into something useful

Let the cows burp and fart to their heart's content!

Keep in mind: Global warming is a hoax and climate change is a religion! It is being used as a pretext by Big Government and the elite to interfere with our lives. It is among the greatest scams and scandals of at least the last 30 years!


Apparently, the authors of this study are propagandists and demagogues or they are naive!


"Although it is less abundant than carbon dioxide, methane gas contributes disproportionately to global warming because it traps more heat in the atmosphere than carbon dioxide, due to its molecular structure. ...


The new catalyst works at room temperature and atmospheric pressure, which could make it easier and more economical to deploy at sites of methane production, such as power plants and cattle barns. ...

To achieve methane conversion without that input of energy, the MIT team designed a hybrid catalyst with two components: a zeolite and a naturally occurring enzyme. Zeolites are abundant, inexpensive clay-like minerals, and previous work has found that they can be used to catalyze the conversion of methane to carbon dioxide. ... 

This hybrid catalyst performs a two-step reaction in which zeolite converts methane to methanol, and then the enzyme converts methanol to formaldehyde. That reaction also generates hydrogen peroxide, which is fed back into the zeolite to provide a source of oxygen for the conversion of methane to methanol. ..."


From the abstract:

"Anthropogenic methane emissions [???], particularly from diffuse and dilute sources, pose a significant challenge for oxidation and valorization as existing methane oxidation routes rely on high temperatures or pressures. Here we report the catalytic coupling of alcohol oxidase with the iron-modified ZSM-5 (Fe-ZSM-5) zeolite catalyst, creating a tandem methanotrophic system that partially oxidizes methane at ambient temperatures and pressures. Methane reacts at Fe-ZSM-5 to produce methanol, which is then oxidized at the enzyme to formaldehyde and hydrogen peroxide. The latter subsequently reacts back at Fe-ZSM-5 and oxidizes methane in a catalytic couple. We show that methane-to-formaldehyde selectivity can exceed 90% at room temperature. The generated formaldehyde was rapidly incorporated into a growing urea polymer, with a material growth rate exceeding 5.0 mg gcat−1 h−1, which matches or exceeds the growth rates of many methanotrophic organisms. This work presents a sustainable route for methane oxidation, driven by oxygen in the air under ambient conditions, producing high-value polymers and valorizing methane emission streams."

Light-powered catalysts destroy forever chemicals aka PFAS

So much for the daily alarmism and hysteria about so called forever chemicals!

Human ingenuity can easily handle it!

By the way, how dangerous are these PFAS actually? We are to believe these must be killer chemicals according to the alarmism and hysteria. I have my doubts.

Winner of Nobel Prize in chemistry Demis Hassabis (CEO of Google Deepmind) describes how his work could transform lives

Recommendable! He is also a great believer in human ingenuity!

The weeds are winning against pesticides. Really!

It is only a matter of time that human ingenuity will tackle this issue! 

No reason for alarmism and hysteria!

But it also tells us that nature is much more able to adopt than we acknowledge!

"Since the 1980s, more and more plants have evolved to become immune to the biochemical mechanisms that herbicides leverage to kill them. This herbicidal resistance threatens to decrease yields—out-of-control weeds can reduce them by 50% or more, and extreme cases can wipe out whole fields.

At worst, it can even drive farmers out of business. It’s the agricultural equivalent of antibiotic resistance, and it keeps getting worse. Weeds have evolved resistance to 168 different herbicides and 21 of the 31 known “modes of action,” which means the specific biochemical target or pathway a chemical is designed to disrupt.

Agriculture needs to embrace a diversity of weed control practices. But that’s much easier said than done. ..."

Researchers thwart resistant bacteria's strategy of one particular bacterium

Good news! A welcome antidote to the deafening and long ongoing hysteria about antimicrobial resistance (AMR)! 

Human ingenuity beats any bug (eventually)! It is an arms race, bugs can not win!

Now that we have also AI at our disposal, bugs have no chance anymore! We should actually feel sorry for bacteria! Caution: satire!

"... One such bacterium is Pseudomonas aeruginosa, which is naturally found in soil and water, but also hospitals, nursing homes and similar institutions for persons with weakened immune systems are home for strains of this bacterium. ...
Now, at team of researchers from Department of Biochemistry and Molecular Biology and Department of Clinical Microbiology, University of Southern Denmark, have discovered a weakness in P. aeruginosa with the potential to become the target for a new way to attack it. ..."

"The team discovered a mechanism, that reduces the formation of biofilm on the surface of P. Aeruginosa. The formation of sticky, slimy biofilm is a powerful tool used by bacteria to protect themselves against antibiotics – a trick also used by P. Aeruginosa.

- This biofilm can be so thick and gooey that antibiotic cannot penetrate the cell surface and reach its target inside the cell ...
- Maybe one day, we could pharmacologically stimulate this mechanism to reduce biofilm development on the surface of P. Aeruginosa. ...
Specifically, the researchers worked with three newly discovered genes in a lab-grown strain of P. aeruginosa. When they overexpressed these genes, they saw a strong reduction of biofilm. ..."

From the abstract:
"Bacteriophages (hereafter “phages”) are ubiquitous predators of bacteria in the natural world, but interest is growing in their development into antibacterial therapy as complement or replacement for antibiotics. However, bacteria have evolved a huge variety of antiphage defense systems allowing them to resist phage lysis to a greater or lesser extent. In addition to dedicated phage defense systems, some aspects of the general stress response also impact phage susceptibility, but the details of this are not well known. In order to elucidate these factors in the opportunistic pathogen Pseudomonas aeruginosa, we used the laboratory-conditioned strain PAO1 as host for phage infection experiments as it is naturally poor in dedicated phage defense systems. Screening by transposon insertion sequencing indicated that the uncharacterized operon PA3040-PA3042 was potentially associated with resistance to lytic phages. However, we found that its primary role appeared to be in regulating biofilm formation, particularly in a clinical isolate of P. aeruginosa in which it also altered tobramycin resistance. Its expression was highly growth-phase dependent and responsive to phage infection and cell envelope stress. Our results suggest that this operon may be a cryptic but important locus for P. aeruginosa stress tolerance."

Researchers thwart resistant bacteria's strategy

Researchers thwart resistant bacteria’s strategy (original news release) Bacteria are experts at evolving resistance to antibiotics. One resistance strategy is to cover their cell walls in sticky and gooey biofilm that antibiotics cannot penetrate. A new discovery could put a stop to this strategy.
