Viral hepatitis has become one of the leading causes of death and disability across the globe – killing at least as many people annually as TB, malaria or HIV/AIDS. This is the finding of new research from scientists at Imperial College London and University of Washington, who analysed data from 183 countries collected between 1990 and 2013.



A new study of the early universe reveals how it could have been formed from an older collapsing universe, rather than being brand new. The universe is currently expanding and it is a common theory that this is the result of the 'Big Bang' - the universe bursting into existence from a point of infinitely dense and hot material.

Liraglutide, produced by Novo Nordisk, has several effects on the body: It increases insulin secretion; it reduces hunger; and it decreases glucagon secretion. Insulin and glucagon are molecules produced by the pancreas that have opposing effects, with insulin reducing blood sugar levels and glucagon increasing blood sugar levels. Insulin is secreted by beta cells in the pancreas and glucagon is secreted by alpha cells in the pancreas.

UT Southwestern Medical Center researchers have uncovered a mechanism that a type of pathogenic bacteria found in shellfish use to sense when they are in the human gut, where they release toxins that cause food poisoning.

The report, “Convergence: The Future of Health,” calls for more integration of physical, life sciences for revolutionary advances in biomedical research. What if lost limbs could be regrown? Cancers detected early with blood or urine tests, instead of invasive biopsies? Drugs delivered via nanoparticles to specific tissues or even cells, minimizing unwanted side effects? While such breakthroughs may sound futuristic, scientists...
