Inspired by clam fishermen reports, researchers used passive acoustic telemetry to gauge the interactions between two highly mobile rays. They monitored the tagged rays in the wild over two years to see how often and when they visited clam leases, designated underwater locations used to produce hard clams of all sizes from littlenecks to chowders. Results provide both good news and bad news for clammers. Rays spent even more time in these clam lease sites than clammers reported or suspected, but it's not necessarily where they prefer hanging out.

There's something most species -- from baboons to humans to horses -- have in common: When they suffer serious adversity early in life, they're more likely to experience hardship later on in life.

Scientists have discovered where butterflies originated and which plants the first butterflies relied on for food. To reach these conclusions, researchers created the world's largest butterfly tree of life, which they used as a guide to trace trace the evolution of butterflies through time in a four-dimensional puzzle that led back to North and Central America.

Scientists have precisely identified base pairs of the human genome that remained consistent over millions of years of mammalian evolution, and which play a crucial role in human disease. The team analyzed the genomes of 240 mammals, including humans and identified base pairs that were 'constrained' -- meaning they remained generally consistent -- across mammal species over the course of evolution. The most constrained base pairs in mammals were over seven times more likely to be causal for human disease and complex trait, and over 11 times more likely when researchers looked at the most constrained base pairs in primates alone.

A new group of mitochondrial viruses confined to the arbuscular mycorrhizal fungi Glomeromycotina may represent an ancestral lineage of mitoviruses.

Much of what is now considered modern medicine originated as folk remedies or traditional, Indigenous practices. These customs are still alive today, and they could help address a variety of conditions. Now, researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria.

Bacteria can rapidly evolve resistance to antibiotics by adapting special pumps to flush them out of their cells, according to new research. Antimicrobial resistance is a growing problem of global significance. The rise of resistant 'superbugs' threatens our ability to use antimicrobials like antibiotics to treat and prevent the spread of infections caused by microorganisms. It is hoped that the findings will improve how antibiotics are used to help prevent further spread of antimicrobial resistance.

A new study finds that early human species adapted to mosaic landscapes and diverse food resources, which would have increased our ancestor's resilience to past shifts in climate.

Scalloped hammerhead sharks hold their breath to keep their bodies warm during deep dives into cold water where they hunt prey such as deep sea squids. This discovery provides important new insights into the physiology and ecology of a species that serves as an important link between the deep and shallow water habitats.

Boreal wetlands are a significant source of isoprene and terpenes, a class of highly reactive organic compounds that have a substantial impact on the Earth's climate, according to a new study.

Surveying the body sizes of Earth's living organisms, researchers found that the planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.

A fossil arthropod entombed in 100-million-year-old Burmese amber has been identified as a new genus and species of froghopper, known today as an insect with prodigious leaping ability in adulthood following a nymphal stage spent covered in a frothy fluid.
