Protein study could help researchers develop new antibiotics
A bacterial enzyme called histidine kinase is a promising target for new classes of antibiotics. However, it has been difficult to develop drugs that target this enzyme, because it is a "hydrophobic" protein that loses its structure once removed from.....»»
Wind tunnel study shows hypersonic jet engine flow can be controlled optically
What if the future of space travel were to look less like Space-X's rocket-based Starship and more like NASA's "Hyper-X," the hypersonic jet plane that, 20 years ago this year, flew faster than any other aircraft before or since?.....»»
Visual explanations of machine learning models to estimate charge states in quantum dots
A group of researchers has successfully demonstrated automatic charge state recognition in quantum dot devices using machine learning techniques, representing a significant step toward automating the preparation and tuning of quantum bits (qubits) fo.....»»
Do vertebrate populations really decline so much? Calculations indicating severe declines might be wrong, says study
A widely-used Living Planet Index (LPI) characterizes the average change in population sizes of vertebrates and is considered one of the main indicators of the state of the planet......»»
"Power rivalry in space": China lunar mission fuels US misinformation
A historic lunar mission has demonstrated China's growing scientific prowess, but the feat has set off a torrent of misinformation targeting the United States that researchers say reflects their bitter competition in space......»»
Japan scientists make smiling robot with "living" skin
Japanese scientists have used human cells to develop an equivalent to living skin that can be attached to robotic surfaces to flash a realistic—if creepy—smile......»»
Phytochemical diversity and herbivory are higher in tropical forests, says study
It is widely accepted that biological interactions are stronger or more important in generating and maintaining biodiversity in the tropics than in temperate regions. However, this hypothesis has not been fully tested in ecology and evolutionary biol.....»»
Early childhood problems linked to persistent school absenteeism
Children who are not considered "school-ready" by their teachers are more than twice as likely to become persistently absent at some point in their education, according to a new study led by the University of Leeds......»»
Researchers just solved AI’s biggest conundrum
That's roughly the draw of a 100W light bulb, and a 50x improvement over the 700W that an NVIDIA H100 GPU consumes......»»
Looking for atmospheres in the ultimate quest for extraterrestrial life
To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba has used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his.....»»
Researchers find genetic stability in a long-term Panamanian hybrid zone of manakins
We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stabl.....»»
Researchers built AI models that use less power than a light bulb
That's roughly the draw of a 100W light bulb, and a 50x improvement over the 700W that an NVIDIA H100 GPU consumes......»»
What a Study on Ultraprocessed Fake Meat and Heart Disease Really Found
A recent study found that eating ultraprocessed plant-based foods was linked to heart attack and stroke risk. But the devil is in the details.....»»

Teens’ Mental Health May Improve When They Help Others
Volunteering in community programs can reduce youth depression and anxiety, researchers are beginning to learn.....»»
Samsung smartphones outsell Apple, but majority of iPhones are flagship models
After doing some studies on Apple Music and Apple News, CIRP is out with a new report on smartphone sales in the US. For the last year, the study found that Samsung moved more smartphones than Apple, but the latter sold a much higher percentage of hi.....»»
Future risk of coral bleaching set to intensify globally, researchers say
An international team of researchers led by the University of Adelaide has projected future marine heat waves will cause coral reefs to be at severe risk of bleaching for longer periods than previously seen......»»
Study demonstrates that a process that turns off DNA transcription can, paradoxically, also turn it on
Researchers led by Kannosuke Yabe, Asuka Kamio, and Soichi Inagaki of the University of Tokyo have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can als.....»»
Researchers capture detailed picture of electron acceleration in one shot
Adjusting experimental methods achieved the first "single-shot" diagnosis of electron acceleration through a laser wakefield accelerator along a curved trajectory, according to a recent study led by University of Michigan researchers. The findings ar.....»»
Scientists discover next-generation system for programmable genome design
In a leap forward for genetic engineering, a team of researchers from the Arc Institute have discovered the bridge recombinase mechanism, a precise and powerful tool to recombine and rearrange DNA in a programmable way......»»
Unlocking the world of bacteria—researchers introduce new approach to make bacteria amenable to genetic engineering
Bacteria populate virtually every habitat on Earth, including within and on our own bodies. Understanding and engineering bacteria can lead to new methods for diagnosing, treating, and preventing infections. Additionally, it presents opportunities to.....»»
