Researchers have discovered how the innate immune system, which responds more generally to dangers detected in the body, can be trained to 'remember' past threats and respond more robustly to future challenges.

Researchers have developed the first map of gene regulation in human neurogenesis, the process by which neural stem cells turn into brain cells and the cerebral cortex expands in size. The scientists identified factors t...

DEEP in a disused zinc mine in Japan, 50,000 tonnes of purified water held in a vast cylindrical stainless-steel tank are quietly killing theories long cherished by physicists. Since 1996, the photomultiplier-tube detect...

You might be surprised to hear that tap water for more than 170 million Americans contains the radioactive element.

Scientists have discovered a surprisingly "visionary" detail about a dinosaur-age bird that had a tooth-filled beak: It could likely see in color.

Dengue virus slowly takes over the endoplasmic reticulum, the production site for a subset of host proteins, and steers clear of the cytosol, the fluid-filled space where the majority of host cellular proteins are synthe...

Biologists look to the past for early genetic development of tiny spider and insect eyes to find potential for research into human visual challenges.

Immune cells that process food and bacterial antigens in the intestines control the intestinal population of fungi, according to a new study. Defects in the fungus-fighting abilities of these cells may contribute to some...

Both the etiology and demographics of podoconiosis, a non-infectious disease which causes massive swelling of the legs, are poorly understood. To help contribute to the global atlas of podoconiosis knowledge, researchers...

Genetic differences between different strains of the same pathogenic bacterial species appear to result in widely varying immune system responses, according to new research.

Wireless headphones, two yo-yos connected by a string, earmuffs: all these items could be used to describe a tiny structure inside a cell's nucleus. For decades, scientists could only speculate about the shape of heteroc...

Researchers have used whole genome analyses and chemogenetics to identify new drug targets and resistance genes in 262 parasite cell lines of Plasmodium falciparum -- protozoan pathogens that cause malaria -- that are re...

The odds are stacked against teenagers who regularly gamble. A new study shows that a 14-year-old who gambles is more likely to struggle at school.

Tuberculosis (TB), an infectious disease which attacks the lungs, claims someone's life every 20 seconds and 1.5 million lives worldwide every year. A cure has eluded scientists for more than a century but, now, research...

Cycling is increasingly popular for transportation, exercise, and leisure, and its impact on sexual health has received a great deal of media attention, especially regarding erectile function. Researchers have now found ...

Medical researchers have developed and validated a genetic tool for predicting age of onset of aggressive prostate cancer, a disease that kills more than 26,000 American men annually.

A new article focuses on harm minimization and smoking cessation, with alternative nicotine products like e-cigarettes emerging as a promising avenue for people who want to quit smoking.

Researchers have, for the first time, coaxed human stem cells to become sensory interneurons -- the cells that give us our sense of touch. The new protocol could be a step toward stem cell-based therapies to restore sens...

A protein pivotal to how the brain acquires knowledge originated from a chance evolutionary event that occurred hundreds of millions of years ago. The protein, called Arc, is involved in storing long-term memories and le...

When babies crawl, their movement across floors, especially carpeted surfaces, kicks up high levels of dirt, skin cells, bacteria, pollen, and fungal spores, a new study has found. The infants inhale a dose of bio bits i...

By exploiting the properties of neutrons to probe electrons in a metal, a team of researchers led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has gained new insight into the behavior of correlate...

Eight newfound Martian cliffs made up of layers of ice could tell us how the Red Planet's climate has changed in the past several million years
