Scientists have crystallized a protein that may help gut bacteria bind to the gastrointestinal tract. The protein could be used by probiotic producers to identify strains that are likely to be of real benefit to people.

A journey that started with a box of bird feet carried three graduate students into the gruesome world of raptors. Normally focused on dinosaurs, the students compared the claws and killing methods of four types of raptors and published a

Researchers recently offered the sharpest-yet picture of how core biochemical pathways in skeletal muscle cells and fat cells are altered in people who suffer from insulin resistance -- a primary defect in type 2 diabetes and obesity. Taking a systems

Not just birds, but also a few species of bats face a long journey every year. Researchers have studied the migratory behavior of the largest extant family of bats, the so-called "Vespertilionidae" with the help of mathematical models. They discovered

The last remaining population of Siberian tigers has likely declined significantly due to the rising tide of poaching and habitat loss, according to a new report

Rocket science is opening new doors to understanding how sounds associated with Navy sonar might affect the hearing of a marine mammal -- or if they hear it at all.

Scientists have identified a new class of therapeutic agents found naturally in soy that can prevent and possibly treat colon cancer, the third most deadly form of cancer. Sphingadienes are natural lipid molecules found in soy that research shows may

Scientists have tested the pain relieving properties of Hyptis crenata -- Brazilian mint.

The world's largest species of monkey "chooses" mates with genes that are different from their own to guarantee healthy and strong offspring, according to a new research study.

Food waste contributes to excess consumption of freshwater and fossil fuels which, along with methane and carbon dioxide emissions from decomposing food, impacts global climate change. Scientists have calculated the energy content of nationwide food waste from the difference between

Popular thinking about how to improve food systems often misses the point, according to the results of a three-year global study of salmon production systems. Rather than pushing for organic or land-based production, or worrying about simple metrics such as

The atomic-level action of a remarkable class of ring-shaped protein motors has been uncovered using a state-of-the-art protein crystallography beamline at the Advanced Light Source. These protein motors play pivotal roles in gene expression and replication, and are vital to

New research on bacterial communities throughout six large Arctic river ecosystems reveals predictable temporal patterns, suggesting that scientists could use these communities as markers for monitoring climate change in the polar regions. The study shows that bacterial communities in the

Recent theories suggesting that half of fishes' food comes from from land-based ecosystems may not hold water. Experiments show that algae, not land-based matter, is needed to build healthy and fertile aquatic organisms.
