Planes, trains, but not automobiles—why GM is developing fuel cells
We talk to GM about its hydrogen fuel cell strategy. Enlarge / Using hydrogen in some of these applications probably makes more sense than building out a network of hydrogen filling stations for passenger cars. (credit: Scharfsinn86/Getty Imag.....»»
East Coast port strike looms as union, management trade wage offers
A strike could stop the flow of everything from food to automobiles at major ports, potentially jeopardizing jobs and stoking inflation weeks ahead of the U.S. presidential election......»»
Developing artificial muscles to give weakened people their strength back
Researchers have succeeded in making artificial muscle fibers from rubber thread, paving the way for sewing the muscles into a blouse and giving renewed strength to the wearer......»»
Study finds about 40% of public supports rationing measures to fight climate change
Rationing of goods such as meat and fuel can both effectively and fairly reduce consumption with high climate impact. Almost 40% of the public say they could accept such measures. These are the findings of new research from the Climate Change Leaders.....»»
Transforming seaweeds into raw materials for aviation fuel and pharmaceuticals
A new technology has been developed to convert common seaweeds such as Kkosiraegi, which are often used in cooking, into high-quality sources for both bio-aviation fuels and energy storage devices. The results were published in the Chemical Engineeri.....»»

Developing an effective cyberwarfare response plan
In this Help Net Security interview, Nadir Izrael, CTO at Armis, discusses how AI has transformed cyberwarfare by amplifying attacks’ scale and sophistication. Izrael emphasizes the need for AI-powered defenses and proactive cybersecurity strat.....»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Building better bone grafts: Nanofibrous scaffolds to activate two main collagen receptors in bone cells
Each year, about 2.2 million bone-grafting procedures are performed worldwide, the gold standard of care being autografting, which uses the patient's own bone for tooth implantation and to repair and reconstruct parts of the mouth, face and skull......»»
Exponential growth brews 1 million AI models on Hugging Face
Hugging Face cites community-driven customization as fuel for diverse AI model boom. Enlarge (credit: Hugging Face / anucha sirivisansuwan via Getty Images) On Thursday, AI hosting platform Hugging Face surpassed 1 milli.....»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
Opinion: Torrential rain represents an opportunity to build a better society
A month's worth of rain has poured down in just a few hours in parts of central and southern England. More than 300 flood-related emergency calls were made, major roads were submerged, trains were delayed, and an enormous sinkhole opened up on a foot.....»»
Semimetal-induced covalency achieves high-efficiency electrocatalysis for platinum intermetallic compounds
Compared with other types of batteries, proton exchange membrane fuel cells have the advantages of high discharge power and no pollution, which is also an important carrier for hydrogen energy conversion and utilization. Platinum intermetallic compou.....»»
GM, Piston plot hydrogen fuel cell factory in Detroit
GM and Piston Automotive are plotting a hydrogen fuel cell factory in Detroit, GM's first standalone plant for fuel cell production......»»
New insights into hot carrier solar cells: Study explores hot electron tunneling and collection to enhance efficiency
Hot carrier solar cells, a concept introduced several decades ago, have long been seen as a potential breakthrough in solar energy technology. These cells could surpass the Shockley–Queisser efficiency limit, which is a theoretical maximum efficien.....»»
Mechanism behind autophagy trigger unveiled
An international research team led by Osaka University has identified a new mechanism crucial for the initiation of autophagy, a self-degradation process cells use to eliminate unneeded or damaged components. In recent years, autophagy has also been.....»»
Yeast chit-chat: How microorganisms communicate food shortages
To grow and survive, tiny organisms such as yeast must sometimes adapt their nutrient sources in response to changes in the environment. FMI researchers have now found that yeast cells communicate with each other to use less favorable nutrients if th.....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Giant panda skin cells transformed into stem cells to help ensure their survival
A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells......»»
New method developed to relocate misplaced proteins in cells
Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally s.....»»
