It may soon be possible to identify Group 4 medulloblastomas –t he most common malignant brain tumor in children — from more aggressive Group 3 tumors. Research based on a little-explored part of RNA, which creates proteins, could lead to the develop…

Feeding honey to hibernating bears helped researchers find the potential genetic keys to the bears’ insulin control, an advance that could ultimately lead to a treatment for human diabetes. Every year, bears gain an enormous amount of weight, then bare…

Researchers have discovered how the immune system can transform into an antibody-making machine capable of neutralizing one of the most elusive viruses out there: HIV. This finding is an important step toward developing effective, long-lasting vaccines…

Scientists have identified a previously unknown barrier that separates the bloodstream from smelling cells in the upper airway of mice. But this barrier ends up keeping some of the larger molecules of the body’s immune system out, and that may be hinde…

Neuroscientists have explored how individual neurons in mice are influenced by two different cognitive and behavioral states — attention and running. These two states were once thought to share a common mechanism. However, in a new study published tod…

In the largest early-medieval population study to date, an interdisciplinary team consisting of geneticists and archaeologists analyzed over 400 individuals from ancient Britain, Ireland, Germany, Denmark and the Netherlands. The results show in detail…

In the United States, 80 percent of university faculty were trained at just 20 percent of the nation’s schools, according to new research from computer scientists.

Sparklers can be a lot of fun — glimmering, fizzing and spitting out arcs of light from handheld sticks or tubes on the ground. But the metals that they’re usually made with limit what the sparks can look like. Now, researchers report that rare-earth …

People who experience frequent bad dreams in middle age are more likely to be diagnosed with dementia later in life, according to research at the University of Birmingham.

The risk of heart attack was about 30% higher with each decade of age as people with HIV got older. However, that risk increased 85% with each decade among people who also have untreated hepatitis C, according to a new analysis of more than 23,000 peop…

Mosquitoes that spread Zika, dengue and yellow fever are guided toward their victims by a scent from human skin. The exact composition of that scent has not been identified until now.

Forensic dramas on TV make it seem easy to determine when fingerprints were left at the scene of a crime. In reality, the oils in fingerprints degrade over time, and it’s difficult to figure out their age. Now, researchers have discovered molecular mar…

Scientists analyzed a variety of children’s textiles. In yet another example of the prevalence of the hazardous chemicals known as PFAS (per- and polyfluoroalkyl substances) in consumer products, industrial products and textiles, researchers have found…
