Improved understanding of genetics offers new hope for diabetics

Diabetes is a widespread health problem, affecting some 400 million people across the planet. With that number only set to rise, it's important that we find new treatments as quickly as possible. Researchers at the University of Montreal are making significant progress in that regard, discovering a common genetic defect in beta cells that may be a big factor in both Type 1 and Type 2 diabetes.Read More

A better model for star aging

Working out the age of any given star in the night sky can be a very difficult task, and estimates are easier to make based on readings from groups rather than individual objects. A new model might significantly improve the situation, providing a conceptual framework to explain the rotation of stars, the intensity of their stellar winds and their X-ray emissions, arriving at a much more accurate estimate of age.Read More

Newly-discovered galaxies are "outrageously luminous"

When looking at light from distant galaxies, the very brightest examples are often given labels like "ultra" or "hyper-luminous." Now, astronomers from the University of Massachusetts at Amherst (UMass Amherst) have observed a new set of galaxies for the very first time that are as much as ten times as luminous as previous findings. The galaxies aren't quite all they seem, however, with their notable appearance a result, at least in part, of a phenomenon known as gravitational lensing.Read More

Gene editing could provide a cure for HIV

While antiretroviral drugs do a good job of keeping HIV infections under control, scientists are working hard to come up with a full cure for the condition. A team of researchers from the Lewis Katz School of Medicine at Temple University is making real progress in that regard, successfully testing a gene editing system, demonstrating its ability to eliminate the virus from DNA in human cells grown in culture.Read More

Exoplanet's orbit is the most eccentric yet

Astronomers at San Francisco State University (SF State) have observed an exoplanet located just 117 light-years from Earth, which exhibits the most eccentric orbit yet found. The light reflected as the planet passed close to its parent star is providing researchers with clues as to the make up of the body's atmosphere, which is thought to be similar to that of Jupiter.Read More

Scientists stumble on nerve cell that tells mice when to stop eating

Obesity is a big health problem, affecting more than one third – or 78.6 million – adults in the United States, and costing more than US$140 billion dollars to treat every year. A new breakthrough in our understanding of how the brain tells the us that we're full could one day lead to all new tools for tackling the widespread condition. The researchers made the discovery by chance while studying learning and memory systems, instead identifying a new nerve type responsible for controlling appetite in mice.

Silencing breast and lung cancer's ability to spread

As a tumor grows, cells can break off it and move around the body, potentially spreading the disease to other organs. Known as metastasis, this process significantly lowers the patient's likelihood of survival, but a new discovery could help doctors tackle it, with researchers form Imperial College London identifying a molecule that shows promise in switching off the process altogether.Read More
