Scientists have developed a way to convert carbon dioxide (CO2), a potent greenhouse gas, into carbon nanofibers, materials with a wide range of unique properties and many potential long-term uses. Their strategy uses tandem electrochemical and thermochemical reactions run at relatively low temperatures and ambient pressure and could successfully lock carbon away to offset or even achieve negative carbon emissions.

Researchers have identified a 3D fragment of fossilized skin that is at least 21 million years than previously described skin fossils. The skin, which belonged to an early species of Paleozoic reptile, has a pebbled surface and most closely resembles crocodile skin. It's the oldest example of preserved epidermis, the outermost layer of skin in terrestrial reptiles, birds, and mammals, which was an important evolutionary adaptation in the transition to...

Researchers have developed a new technique to measure the number of chromosomes in ancient genomes more precisely, using it to identify the first prehistoric person with mosaic Turner syndrome (characterized by one X chromosome instead of two [XX]), who lived about 2500 years ago. Read more ›

Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion -- shedding light on the formation of planets like Earth. Read more ›

Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar and Martian-rock dust, an important piece in making long-term space travel possible. Using machine learning and computational modeling, researchers have found about half a dozen good candidates for solvents that can extract materials on the moon and Mars usable in 3D printing. The powerful solvents, called ionic liquids, are salts... Read more ›

A Rutgers biophysical chemist and his brother, a political scientist on the West Coast, have joined intellectual forces, realizing a long-standing dream of co-authoring an article that bridges their disciplines involving cells and society. In their paper, they have proposed that powerful parallels exist between the microscopic, natural world of cells and molecules and the human-forged realm of organizations and political systems.

Phosphorus is essential for undisturbed plant growth and development. However, in many soils, phosphorus is only poorly available. One mechanism used by plants to increase phosphorus availability is the release of malate, an organic acid, which can form complexes with iron or aluminium in the soil, thereby liberating sorbed phosphate. However, this response can also result in iron overaccumulation, which can inhibit root growth. Read more ›

Researchers have developed a new technology that uses meta-optical devices to perform thermal imaging. The approach provides richer information about imaged objects, which could broaden the use of thermal imaging in fields such as autonomous navigation, security, thermography, medical imaging and remote sensing.

A new study suggests that once developed, a universal vaccine in advance of the next coronavirus epidemic/pandemic can save up to 7 million hospitalizations and 2 million deaths even when it is the only intervention being implemented and its efficacy is as low as 10 percent. Read more ›

Scientists have produced an organoid model of the human conjunctiva. These organoids mimic the function of the actual human conjunctiva, a tissue involved in tear production. Using their new model, the researchers discovered a new cell type in this tissue: tuft cells. The tuft cells become more abundant under allergy-like conditions and are therefore likely to play a role in allergies. The organoid model can now be used to test... Read more ›

Researchers have created the world's largest ancient human gene bank by analyzing the bones and teeth of almost 5,000 humans who lived across western Europe and Asia up to 34,000 years ago. By sequencing ancient human DNA and comparing it to modern-day samples, the international team of experts mapped the historical spread of genes -- and diseases -- over time as populations migrated. They found: The startling origins of neurodegenerative... Read more ›

Researchers have now been able to study the surface of iron and ruthenium catalysts when ammonia is formed from nitrogen and hydrogen. A better knowledge of the catalytic process and the possibility of finding even more efficient materials opens the door for a green transition in the currently very CO2-intensive chemical industry.

The largest ever primate Gigantopithecus blacki went extinct when other Asian great apes were thriving, and its demise has long been a mystery. A massive regional study of 22 caves in southern China explores a species on the brink of extinction between 295,000 and 215,000 years ago. As the environment became more seasonal, forest plant communities changed Primates such as orangutans adapted their eating habits and behaviors in response but... Read more ›

Researchers discovered that plants manage iron deficiency without helping 'bad' bacteria thrive by eliminating the molecular signal for iron deficiency, and that the iron deficiency signaling pathway and the plant immune system are deeply intertwined. Their findings provide a new target for boosting plant resilience in the face of climate change, and offer new insight into plant and animal microbiomes. Read more ›

A new study confirms that spring snowpacks across the Northern Hemisphere have shrunk significantly over the past 40 years due to human-driven climate change, putting hundreds of millions of people worldwide at risk of a water crisis. The Southwestern and Northeastern U.S. saw among the steepest declines, with more than 10% of the spring snowpack lost per decade, which the researchers expect will accelerate with further warming. Many heavily populated... Read more ›

Combining a biological heart and a silicone robotic pump, researchers created a biorobotic heart that beats like a real one, with a focus on a valve on the left side of the heart. The heart valve simulator can mimic the structure, function, and motion of a healthy or diseased heart, allowing surgeons and researchers to demonstrate various interventions while collecting real-time data.
