New Portable Tool Analyzes Microbes in the Environment

Imagine a device that could swiftly analyze microbes in oceans and other aquatic environments, revealing the health of these organisms - too tiny to be seen by the naked eye - and their response to ... read more

'Jumping Genes' Help Stabilize DNA Folding Patterns

The DNA molecule inside the nucleus of any human cell is more than six feet long. To fit into such a small space, it must fold into precise loops that also govern how genes are turned on or off. New ... read more

The Skin of Earth Is Home to Pac-Man-Like Protists

The most common groups of soil protists behave exactly like Pac-Man: moving through the soil matrix, gobbling up bacteria according to a new ... read more

TP53 Gene Variant in People of African Descent Linked to Iron Overload, May Improve Malaria Response

A rare, African-specific variant of the TP53 gene called P47S causes iron accumulation in macrophages and other cell types and is associated with poorer response to bacterial infections, along with ... read more

Why Eating Yogurt May Help Lessen the Risk of Breast Cancer

One of the causes of breast cancer may be inflammation triggered by harmful bacteria suggest researchers. Scientists advise consuming natural yogurt, which contains beneficial bacteria which dampens ... read more

New Species of Allosaurus Discovered in Utah

A remarkable new species of meat-eating dinosaur, Allosaurus jimmadseni, was just unveiled. The huge carnivore inhabited the flood plains of western North America during the Late Jurassic Period, ... read more

Scientists Capture Molecular Maps of Animal Tissue With Unprecedented Detail

Scientists have refined a technique called mass spectrometry imaging (MSI) that translates reams of data into detailed visuals of the molecular makeup of biological samples. Their work features ... read more

Novel Communication Between Intestinal Microbes and Developing Immune Cells in the Thymus

Researchers discover microbes regulate the development of specialized immune cells in the thymus that play a critical role in mucosal ... read more

Sharp Increase in Ningaloo Whale Shark Injuries Might Be Due to Boat Encounters

Almost one-fifth of the whale sharks (Rhincodon typus) in Western Australia's Ningaloo Reef Marine Park show major scarring or fin amputations, with the number of injured animals increasing in ... read more

Why Cells Need Acidic Lysosomes

Little organs within cells called lysosomes digest unwanted material. And like stomachs, they must be acidic to do so. If they aren't, cells stop growing. Researchers wanted to know ... read more

Jewel Beetles' Sparkle Helps Them Hide in Plain Sight

Bright colors are often considered an evolutionary tradeoff in the animal kingdom. Yes, a male peacock's colorful feathers may help it attract a mate, but they also make it more likely to be ... read more

Snake Stem Cells Used to Create Venom-Producing Organoids

Organoids have become an important tool for studying many disease processes and testing potential drugs. Now, they are being used in a surprising and unexpected way: for the production of snake ... read more

West Nile Virus Triggers Brain Inflammation by Inhibiting Protein Degradation

West Nile virus (WNV) inhibits autophagy -- an essential system that digests or removes cellular constituents such as proteins -- to induce the aggregation of proteins in infected cells, triggering ... read more

Scientists Discover How a Curvy, Stomach Cancer-Causing Bacterium Maintains Its Shape

A new study shows how a common stomach bacterium is able to keep its corkscrew-like shape as it grows. Disrupting the shape could point the way for future, more-specialized antibiotics that prevent ... read more

Unravelling Arthropod Genomic Diversity Over 500 Million Years of Evolution
