Climate change could kill more than 500,000 adults in 2050 worldwide due to changes in diets and bodyweight from reduced crop productivity, according to new estimates. The research is the strongest evidence yet that clim...

A new study adds to the evidence that energy drinks may be bad for your heart.

In a finding with enormous implications for cancer diagnostics and therapeutics, scientists have discovered that breaches in looping chromosomal structures known as "insulated neighborhoods" can activate oncogenes capabl...

The sexes can have markedly different responses to the same investigations. Not reporting on the sex and age of animal models could significantly reduce the reliability and reproducibility of studies, and lead to drugs t...

Babies born in the late preterm period -- between 34 and 36 weeks gestation -- benefit from the use of antenatal corticosteroids to help mature the baby's lungs, new research shows.

A new kind of stem cell, one that could lead to advances in regenerative medicine as well as offer new ways to study birth defects and other reproductive problems, has been discovered by a team of researchers.

PGK1, a glycolytic enzyme, has been found to play a role in coordinating cellular processes crucial to cancer metabolism and brain tumor formation, according to results of a new study.

Healthy cells actively collaborate with tumors by creating a mesh of collagen that encourages cancer cells to build new blood vessels, a new study shows. Researchers found that 'collaborator' cells build a beneficial env...

Scientists have discovered how to make a new type of cell that is in between embryonic stem cells and adult heart cells, and that may hold the key to treating heart disease. These induced expandable cardiovascular progen...

Inhibiting the transfer of calcium ions into the cell's powerhouse is specifically toxic to cancer cells, suggesting new ways to fight the disease. Calcium addiction by mitochondria is a novel feature of cancer cells. Th...

P53, a tumor suppressor referred to as has often been described as the 'guardian of the genome,' may also be the 'guardian of obesity.' New research found that a variant of the gene is heavily implicated in metabolism, w...

For decades, scientists have struggled to develop a comprehensive census of cell types in the brain. Now, researchers describe powerful new approaches to systematically identify individual classes of neurons in the spina...

One of the most crucial and elusive goals of an effective HIV vaccine is to stimulate antibodies that can attack the virus even as it relentlessly mutates. Now a research team has tracked rare potent antibodies in an HIV...

Rhesus monkeys were completely protected from Ebola virus when treated three days after infection with a compound that blocks the virus's ability to replicate. These encouraging preclinical results suggest the compound, ...

Using someone else's medication is the most common form of prescription stimulant misuse among adolescents, according to a study, which found that 88 percent of teens who used the drugs non-medically in the past 30 days ...

A brain inflammation marker has been identified in patients at early asymptomatic stages of Alzheimer's disease. This secreted marker molecule, which can be measured from cerebrospinal fluid taps, may provide clinicians ...

How enzymes -- the biological proteins that act as catalysts and help complex reactions occur -- are 'tuned' to work at a particular temperature is described in new research.

A new study examining elder abuse-released has found that older adult victims living alone with their abuser were up to four times more likely to endure more severe levels of mistreatment. The study suggests that the add...

The Pentagon is about to pay hackers to break into government security systems.

Biological molecules could be used to solve intractable problems that traditional computers can't crack, new research suggests.

Imagine a health care robot that could display the patient's temperature and pulse, and even reacts to a patient's mood. It sounds futuristic, but a team of Cornell graduate students - led by Rob Shepherd, assistant prof...
