Sniffles, snorts and blows of runny noses are the hallmarks of cold and flu season -- and that increase in mucus is exactly what bacteria use to mount a coordinated attack on the immune system, according to a new study. The team found that the thicker the mucus, the better the bacteria are able to swarm. The findings could have implications for treatments that reduce the ability of bacteria to spread.

Aquaporins, which move water through membranes of plant cells, were not thought to be able to permeate sugar molecules, but researchers have observed sucrose transport in plant aquaporins for the first time, challenging this theory.

Pregnancy brings a rise in pancreatic beta cells -- the cells that produce insulin. Shortly after birth, these cells return to their normal levels. The mechanisms behind this process had remained a mystery. But now a research group has revealed that white blood cells called macrophages 'eat' these cells.

Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.

Scientists have amassed genome data for dozens of 'magic mushroom' isolates and cultivars, with the goal to learn more about how their domestication and cultivation has changed them. The findings may point the way to the production of intriguing new cultivars, say the researchers.

While we often think of diseases as caused by foreign bodies -- bacteria or viruses -- there are hundreds of diseases affecting humans that result from errors in cellular production of its proteins. A team of researchers recently leveraged the power of cutting-edge technology, including an innovative technique called glycoproteomics, to unlock the carbohydrate-based code that governs how certain classes of proteins form themselves into the complex shapes necessary to keep us healthy.

Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthparts, suggesting they likely sucked blood. That's noteworthy because, among modern-day mosquitoes, only females are hematophagous, meaning that they use piercing mouthparts to feed on the blood of people and other animals.

Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.

Researchers have developed a new technique called MAbID. This allows them to simultaneously study different mechanisms of gene regulation, which plays a major role in development and disease. MAbID offers new insights into how these mechanisms work together or against each other.

An international team of researchers has elucidated the process by which the major flavonoids naringenin, apigenin, and genistein are metabolized in the body. These findings are fundamental in elucidating the correlation between the metabolism of flavonoids in the body and their potential health benefits.
