Researchers have developed a new water-splitting process and material that maximize the efficiency of producing green hydrogen, making it an affordable and accessible option for industrial partners that want to convert to green hydrogen for renewable energy storage instead of conventional, carbon-emitting hydrogen production from natural gas.
Before the introduction of the domestic horse in Mesopotamia, valuable equids were being harnessed to ceremonial or military four wheeled wagons and used as royal gifts, but their true nature remained unknown. According to a palaeogenetic study, these prestigious animals were the result of a cross between a domestic donkey and a wild ass from Syria, now extinct. This makes them the oldest example...
Researchers report successfully removing the nucleus from a type of ubiquitous cell, then using the genetically engineered cell as a unique cargo-carrier to deliver therapeutics precisely to diseased tissues.
The Internet of Things (IoT) is completely enmeshed in our daily lives, a network of connected laptops, phones, cars, fitness trackers -- even smart toasters and refrigerators -- that are increasingly able to make decisions on their own. But how to ensure that these devices benefit us, rather than exploit us or put us at risk? New work proposes a novel framework, the 'impact universe,' that can...
A world-first study has revealed how space travel can cause lower red blood cell counts, known as space anemia. Analysis of 14 astronauts showed their bodies destroyed 54 percent more red blood cells in space than they normally would on Earth, according to a new study.
A new study has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.
Scientists have pinpointed a gene that helps deadly E. coli bacteria evade antibiotics, potentially leading to better treatments for millions of people worldwide.
Researchers studying how small worms defend themselves against pathogens have discovered a gene that acts as a first-line response against infection. They identified 'ZIP-1' as a centralized hub for immune response, a finding could have implications for understanding human immunity against viruses.
Researchers show that high-frequency plasma waves in the Geospace can generate low-frequency plasma waves through wave-particle interactions by heating up low-energy ions, unveiling a new energy transfer pathway in collisionless plasma.
Just like explorers need maps, scientists require guides to better understand and advance new technology. A neuromorphic device, which can mimic the neural cells in our brain, has lacked such a guideline and created headaches for scientists trying to understand their operational mechanisms. That is until now after a research group created a map that provides rational design guidelines for...
Researchers have completed a comprehensive analysis of the head width of over 1500 modern and fossilized species of termites and determined that their size isn't shrinking at a geological timescale.
Being the first element to form, hydrogen holds clues about the distribution of matter in our universe. Normally a gas, hydrogen exists as a solid under ultra-high-pressure conditions commonly found in the core of giant gaseous planets. However, the structures of solid hydrogen have remained elusive owing to difficulties in replicating such conditions experimentally. Now, a new study sheds light...
Do we have our best ideas while walking? Indeed, but even small movements while sitting improve creativity, as two researchers have discovered.
Researchers have demonstrated in the lab how well a mineral common at the boundary between the Earth's core and mantle conducts heat. This leads them to suspect that the Earth's heat may dissipate sooner than previously thought.
A mathematical model revealed that the optimal time to initiate immune-modulating therapy in COVID-19 differed according to patients' medical history and risk factors. Different patients also required different types of immunomodulation for optimal therapy.
Characterizing the way, manner or pattern of evolution in tumors may be important for clinical forecasting and optimizing cancer treatment. Researchers are systematically examining how spatial structure influences tumor evolution. To do this the group developed a computational model with the flexibility to simulate alternative spatial structures and types of cell dispersal.
An international team of researchers found that the brightly colored jumping spider Saitis barbipes could not see its own vivid reds.
Researchers have developed an artificial intelligence platform to analyze potentially cancerous lesions in mammography scans to determine if a patient should receive an invasive biopsy. But unlike its many predecessors, the algorithm is interpretable, meaning it shows physicians exactly how it came to its conclusions.
A research team reports that a parasite tricks mitochondria into shedding large structures from their 'skin', thus turning off their defenses.
The free-energy principle can explain how neural networks are optimized for efficiency, according to new research. This finding will be useful for analyzing impaired brain function in thought disorders as well as for generating optimized neural networks for artificial intelligences.
A new study shows that unvaccinated pregnant people with COVID-19 are more likely to have poor birth outcomes even if they did not experience severe respiratory problems during infection.
One in 10 people may have clinically relevant levels of potentially infectious SARS-CoV-2 past the 10 day quarantine period, according to new research.
A molecule of RNA called CARMN has been found in abundance in the healthy smooth muscle cells that help give our blood vessels strength and flexibility, and distinctly decreased in vascular diseases like atherosclerosis, a major cause of heart attack and stroke, scientists report.
A mutation in the gene that causes fibrodysplasia ossificans progressiva (FOP) doesn't just cause extra bone growth but is tied to a problem in generating new muscle tissue after injury, according to new research.
