Brought to Pennsylvania from Peru in the early 1900s, the mummy's origins are murky.

Clay on the Martian surface may be able to sustain and nourish microbes, and the Curiosity rover has just rolled into an area on Mars that's chock full of it

Pathogenic gene mutations causing a type of intractable skin disease can be eliminated from some parts of patients' skin as they age, according to researchers. This represents a form of natural gene therapy.

Investigators report that autoantibody production in HIV-positive patients who have undergone antiretroviral therapy is linked to levels of Staphylococcus products in their blood.

Photoacoustic microscopy technique allows researchers to analyze metabolic characteristics of cancer cells with laser light and high-frequency ultrasonic sensing.

Researchers have published new insights on how bacteria cause infections, which may help with future infection treatments.

Face-to-face workshops based on the psychology of behavior change and disaster preparedness can be used to prompt households to take action to protect themselves against disasters such as earthquakes, fires and floods, a...

New findings reveal how immune cells turn off killer T cells, pointing to new drug targets that can improve the success of cancer immunotherapy.

New research in nonhuman primates shows that heavy use of alcohol can actually slow the rate of growth in developing brains. The study, to be published April 1, in the journal eNeuro, shows that heavy alcohol use reduced...

In a new study to investigate the relationship among depressive disorders or symptoms, HIV status and mortality, researchers report that symptoms of depression are moderately associated with death among veterans with HIV...

Scientists have discovered a new mechanism of gene transcription in tumor cells. Their study identifies novel strategies to develop innovative anti-cancer drugs.

A new study finds that Medicare costs tend to be lower in counties with more forests and shrublands than in counties dominated by other types of land cover. The relationship persists even when accounting for economic, ge...

Many cancers are relatively harmless at their site of origin, and it is only when they metastasize to sites like the brain, bones, lungs, and liver that they become especially dangerous. And so, in addition to stopping t...

There are issues about the appropriateness of accepting or using MAID body donations; communication with donors including consenting processes, and the transparency surrounding MAID donation with staff, faculty and stude...

Cyclists in London should take a different route back home during evening peak-time hours to avoid breathing in harmful black carbon from vehicles.

Compared to privately insured patients, individuals who lack insurance or use Medicaid are more likely to be transferred to another hospital after receiving initial treatment in the emergency department (ED). The uninsur...

For the first time ever, scientists have imaged the process by which an individual immune system molecule is switched on in response to a signal from the environment, leading to the critical discovery that the activation...

While women outnumber men as ob/gyn practitioners, they still make significantly less money and the pay gap extends to subspecialties like reproductive endocrinology and infertility, according to researchers.

Researchers found that one mechanism by which antibiotics induce drug-resistance mutations in bacteria is by triggering the generation of high levels of toxic molecules called reactive oxygen species (ROS). Additionally,...

Scientists discovered a light-dependent molecular pathway that regulates how blood vessels develop in the eye. The findings suggest it may be possible to use light therapy to help premature infants whose eyes are still d...

Neuroscientists have discovered a group of neurons that are responsible when a frightening memory re-emerges unexpectedly, like Michael Myers in every 'Halloween' movie. The finding could lead to new recommendations abou...

Restriction or inhalation of common sugar could one day treat a range of respiratory diseases, according to new research. The study in mice reveals how the ability of cells to use glucose helps to regulate the immune sys...
