In a small study in the Democratic Republic of Congo, 6-week-old infants with healthy gut microbiomes were less likely to contract malaria in their first year of life. While the study is preliminary, it suggests the possibility ...

A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago.

Natural hallucinogens, such as psilocybin, mescaline, N,N-dimethyltryptamine (DMT) and related compounds, have generally received attention for their effects on human perception, emotion and cognition. Recently, interest ...

Strongly interacting quantum particles are key to some of the most fascinating phenomena in modern physics—from magnetism and superconductivity to topological states. Yet the complexity of such systems makes many of their ...

Chiral 2D metal halide perovskites (MHPs) are among the most promising materials for future technologies that exploit the spin of electrons in spin-based optoelectronics, or spintronics, but getting them to perform consistently ...

Aniline can now be transformed into pyridine without adding any catalysts, oxidants or toxic reagents. In a recent study published in the Journal of the American Chemical Society, researchers achieved skeletal editing, involving ...

A research team at Mahidol University, Thailand, has discovered that tosyl groups, long regarded as routine synthetic handles, can actively guide the formation and behavior of pillararenes—a class of pillar-shaped macrocyclic ...

When bacteria are under antibiotic attack, it is not "every man for himself." Researchers at Baylor College of Medicine and colleagues from collaborating institutions have discovered that bacterial populations work as a team ...

Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist Philip W. Anderson first described a phenomenon via which irregularities or other sources of disorder ...

The retina of the human eye contains 6–7 million cone cells. These cells contain light-sensitive proteins known as cone opsins. They enable us to perceive our surroundings in detail in daylight. They allow us to see the world ...

Nearly every massive galaxy observed hosts a supermassive black hole at its center. NASA's James Webb Space Telescope has discovered that some of these supermassive black holes may even be too big for the galaxy they're found ...
