Chemists have demonstrated a new approach to blocking cancer-drug resistance that they believe could be applied to any type of cancer. In a dramatic result, the approach — which involves chemically combining two existing drugs in a new way — produced 50 percent smaller tumors in mice compared with a traditional treatment with the same drugs given separately.

Scientists used genetic testing in over 900 shelter dogs to identify breed heritage in the largest study of its kind. The researchers found widespread genetic diversity: 125 breeds in the sample and an average of three breed matches per dog. The accuracy of shelter staff in identifying more than one breed in the dog's heritage based just on physical appearance was only 10 percent. How breed labels can impact shelter dogs is discussed.

A new method developed by bioengineers has disentangled the 'see-saw' balance of protein synthesis and degradation in single cells.

As soon as a baby is born, its immune system starts to change dramatically in response to the bacteria, viruses and so forth in its new environment, a phenomenon that is common to all babies.

Scientists have discovered a novel function of blood vessels in orchestrating the proper development of neuronal cellular networks in the brain.

An international team of researchers has discovered new species of alvarezsaurs, an enigmatic group of dinosaurs that share many characteristics with birds.

Patients with a rare disease called Dravet syndrome are at heightened risk for sudden unexplained death in epilepsy. Researchers are using stem cells to identify the effects of a gene mutation on the heart, which may lead to fatal arrhythmias.

Technological innovation, expansion of the use of frontline personnel such as community health workers, and rapid increases in health care financing are likely to be instrumental to achieving universal health care (UHC) in countries around the world, according to a wide-ranging review of the scientific evidence on UHC.

Scientists have discovered how a type of RNA, called Evf2 enhancer RNA, regulates key genes during a critical stage in embryonic brain development.

Using technology similar to what is found in many eye doctors' offices, researchers have detected evidence suggesting Alzheimer's in older patients who had no symptoms of the disease.
