Patients with well-supported immune cells in their tumors are more likely to control their cancers' growth for a longer time, an observation that could guide treatment decisions after surgery for kidney cancer. In additi...

A new study reveals the mechanism that helps pancreatic cancer cells avoid starvation within dense tumors by hijacking a process that pulls nutrients in from their surroundings.

The number of malnourished people is increasing worldwide. More than two billion people suffer from a lack of micronutrients. Infant mortality rates are unacceptably high. Against this background, there is a need for the...

A team of researchers has now identified a specific circuit in the brain that alters food impulsivity.

Scientists from Australia and the US have discovered and identified the genetic cause of a previously unknown human autoinflammatory disease. The researchers determined that the autoinflammatory disease, which they terme...

Researchers have now demonstrated a powerful 'experimental evolution' method to discover details of protein shape and function, and the method may find uses across a very broad spectrum of biomedical research.

What if scientists could create more effective drugs to treat cancers and other diseases by better targeting specific sites on proteins in the body?

A new technology to produce safer 'hybrid' viruses at high volumes for use in vaccines and diagnostics for mosquito-borne diseases has been developed.

An international team of scientists have made drug-like molecules inspired by a chemical found in a tropical flower, that they hope could in the future help to treat deadly pancreatic cancer.

Efforts to prevent new HIV transmissions in the US must be accompanied by addressing HIV-associated comorbidities to improve the health of people already living with HIV, experts assert.

Participants who ate a diet high in red and processed meat, fried food, refined grains and high-fat dairy were three times more likely to develop late-stage age-related macular degeneration.

Neuroscientists lay out the the few knowns and many unknowns that must be understood to determine why sensory stimuluation of 40Hz brain rhythms have broad effects, particularly in Alzheimer's models.

Mountaineers and winter sports enthusiasts know the dangers of frostbite -- the tissue damage that can occur when extremities, such as the nose, ears, fingers and toes, are exposed to very cold temperatures. However, it ...

Last year, the first permitted 3D printed house in the US went up in Austin, Texas. The house was a buzz-generating proof of concept, a wacky example of the cool things tech can do. At the time, its creators--constructio...

Physicists at the University of Alberta have created a molecular colourant that can emit light in a wider range of colours than any other molecule currently available.

A common misconception is that evolution naturally selects for biological complexity, eventually creating advanced organisms like us. That couldn't be further from the truth

(Wiley) Ethylene, or ethene, is a primary feedstock for the chemical industry, including as a starting material for the production of a wide variety of plastics. In the journal Angewandte Chemie, scientists have now intr...

Predators are a problem for Trinidad's killifish: in streams where the problem is worst the killifish grow more brain cells, perhaps to help evade the hunters

Pneumonia is a common infection that causes inflammation in one or both lungs. It's typical symptoms are a cough with phlegm, fever, chills and difficulty breathing.

While genetics may increase your risk of developing dementia, other factors such as lifestyle and environment may play a key role in the development and progression of Alzheimer's disease.

WHY ARE whales so big? One answer is simply that they can be. The size of land animals is constrained in part by their need to support themselves against the force of gravity. Marine creatures have that support provided ...

Chronic insomniacs who pull an all-nighter perform twice as bad on reaction time tests as normal sleepers who forgo a night's sleep.
