Epithelial cells grown on a plastic dish are worse at segregating their chromosomes than epithelial cells growing in mice, a new study shows. The results may help explain why chromosomes go awry in cancer.

The 'molecular dirt' found on any surface can change the properties of the material. A new method has been developed to study this. By creating ultra-pure ice in a vacuum chamber and melting it the world's cleanest water drops were created and applied to titanium dioxide surfaces. The 'dirt' turns out to be a single-molecule-thick layer of two organic acids. This is surprising, because only minute traces of these acids are found in air.

A pioneering research collaboration into yellow fever virus (YFV) has shed new light on the exceptional recent outbreak in Brazil and how the virus spreads. The findings have implications for monitoring viral transmission and could potentially contribute to a strategy for eliminating YFV worldwide.

Physicists find the first instance of Dicke cooperativity in a matter-matter system. The discovery could help advance the understanding of magnetic phenomena.

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.
