Overdoses involving benzodiazepines are "a public health problem that has gone under the radar," a researchers says.

The division of mammalian egg cells depends on cohesin proteins that embrace chromosomes before birth and are not renewed thereafter, scientists have discovered. The cohesin complex is remarkably long-lived but eventuall...

Researchers have demonstrated a causal relationship between rehabilitation-induced change of brain circuits and functional recovery through forced limb use in rats with stroke, providing crucial information for devising ...

Researchers have shown how a bizarrely shaped black hole could cause Einstein's general theory of relativity, a foundation of modern physics, to break down. However, such an object could only exist in a universe with fiv...

The radioactive material allegedly stolen from an oil field in Basra, Iraq, is likely too small to do as much damage as a dirty bomb, but its psychological effects could be huge, one expert says.

For women with the most common type of breast cancer, a new way to analyze magnetic resonance images (MRI) data appears to reliably distinguish between patients who would need only hormonal treatment and those who also n...

A research team has examined whether a single exposure to alcohol can induce memory and behavioral changes that could promote future drinking. Their data suggest that the perceived benefits of alcohol are registered and ...

The germinal centers that form in the body's lymph nodes work as a fitness boot camp in which B cells evolve to produce antibodies of increasingly higher affinity to an invading pathogen. This new finding overturns a pre...

The first comprehensive, cross-species genomic comparison of all 20 known species of Leptospira, a bacterial genus that can cause disease and death in livestock and other domesticated mammals, wildlife and humans, has no...

Engineered gene drives, which have the potential to spread desirable genes throughout wild populations or to suppress harmful species, have received a lot of recent attention because of their potential to control organis...

The care provided by the US military health care system to service members suffering from post-traumatic stress disorder and depression is good in some areas, but needs improvement in other realms, according to a new stu...

The mitochondrion isn't the bacterium it was in its prime, say two billion years ago. Since getting consumed by our common single-celled ancestor the 'energy powerhouse' organelle has lost most of its 2,000+ genes, likel...

A new gadget can help people identify pollutants -- some smaller than the width of a hair -- in their homes.

Humans use the time delay between the arrival of a sound wave at each ear to discern the direction of the source. In frogs, lizards and birds the distance between the ears is too small. However, they have a cavity connec...

Preliminary findings from a study examining the genetic alterations in HPV-positive oropharyngeal squamous cell carcinoma were recently presented. Researchers found differences in the genetic mutations of HPV-positive or...

An experimental drug may aid patients with traumatic brain injury (TBI), for which there is currently no effective treatment to prevent increased risk of dementia or other neurologic complications.

A next-generation sequencing (NGS)-based panel will be designed specifically for pediatric cancer research, say scientists. The assay would be designed to target biomarkers associated with childhood cancers.

Each fall, doctors stress the importance of getting a flu shot: influenza is the most frequent cause of death from a vaccine-preventable disease in the United States. But on-time delivery of the vaccine can be tenuous, a...
