Titanium is the leading material for artificial knee and hip joints because it's strong, wear-resistant and nontoxic, but an unexpected discovery by physicists shows that the gold standard for artificial joints can be im...

Parasitism has independently evolved at least 223 times, leading to millions of parasitic species on Earth.

A DNA sequencer that was just delivered to the International Space Station can test not just known Earthly organisms. It could possibly analyze samples taken from alien life, NASA said.

In today's world of ever-increasing digital information storage and computation, the next information storage revolution seeks to exploit a novel effect arising from the relativistic physics of Einstein which allows to m...

In football, player-vs.-player hits will likely cause more severe head impacts than other impacts, according to a new study.

A new study of the gut microbiomes of humans, chimps, bonobos and gorillas shows that at least two major groups of bacteria have cospeciated with these hosts, with a lineage going back at least 15 million years to our la...

Researchers have identified a new way that tuberculosis bacteria get into the body, revealing a potential therapeutic angle to explore.

For the first time, research shows that changes over time in the volume of patients seen by trauma centers influence the likelihood of seriously injured patients living or dying. The findings mean that changes in patient...

A new study upends the status quo to combatting schistosomiasis, which affects 250 million people worldwide. The team suggests that the spread of the parasitic disease is curbed more effectively with ecological intervent...

A better understanding of HIV latency is the key to eradicating the virus, researchers write in a new article. Worldwide, 37 million people are living with HIV. A cure has proved elusive due to viral latency -- a period ...

In humans and other mammals, the cerebral cortex is responsible for sensory, motor, and cognitive functions. A new study shows that the global architecture of the cortical networks in large-brained primates and small-bra...

A study reports that successful Schistosomiasis control programs over the past century relied, at least in part, on reducing the freshwater snails that are an essential host in the parasite life cycle.

Trypanosome parasites cause sleeping sickness in Africa. If left untreated, the infection causes coma and eventually death. A study takes a close look at what happens after an infected tsetse fly transmits parasites into...

A new study will help research into regenerative medicine and potentially also help understand neurodegenerative diseases such as Alzheimer's.

Capitalizing on experimental genetic techniques, researchers have demonstrated that temporarily turning off an area of the brain changes patterns of activity across much of the remaining brain.

Researchers have now directly connected the Aedes aegypti mosquito with Zika transmission in the Americas, during an outbreak in southern Mexico. The findings will help scientists to better target efforts for controlling...

More than one in three -- an estimated 328,000 -- students in grades seven to 12 report moderate-to-serious psychological distress, according to new survey results in Ontario, Canada. Girls are twice as likely as boys to...

People living with chronic low back pain (cLBP) are more likely to use illicit drugs -- including marijuana, cocaine, heroin, and methamphetamine -- compared to those without back pain, reports a study.

Elderly patients suffering a low energy wrist (distal radius) fracture are more likely to have difficulties with balance, placing them at risk for future injuries, according to a new study.

Adaptation in reaching -- gradual improvement of motor control in response to a perturbation -- is a central issue in motor neuroscience. However, even the cortical origin of errors that drive adaptation has remained elu...

Scientists have taken a detailed look inside the small, densely packed structure of the inactive X chromosome found in female mammals called the Barr body.

A key gene enables the repair of injured muscle throughout life, according to a study in mice. The study results further suggest that this "overlooked" gene may play an important role in sarcopenia, the loss of muscle ti...
