Chemists synthesize new class of carbenes - potential for pharmaceutical industry

Chemists at the University of California, Riverside have synthesized a new class of carbenes - molecules that have unusual carbon atoms - that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs.

New phenomenon in which one bacterial cell can stop the growth of another on physical contact

Scientists have discovered a new phenomenon in which one bacterial cell can stop the growth of another on physical contact. The bacteria that stop growing may go into a dormant state, rather than dying. The findings have implications for management of chronic diseases, such as urinary tract infections.

Enzyme called matriptase, when left to its own devices, can cause cance

Scientists at the National Institute of Dental and Craniofacial Research (NIDCR) and colleagues report in animal studies that a single, scissor-like enzyme called matriptase, when left to its own devices, can cause cancer.

Method to propagate mouse brain stem cells derived from ES cells

It's hard to grow stem cells in a dish. In particular, while it is possible to multiply mouse embryonic stem cells in culture, propagating stem cells that are specific to distinct tissues (e.g. neural stem cells) has proven to be a challenge.

Large-scale computer simulations reveal new insights into antibiotic resistance

Large-scale computer simulations have pinpointed a tiny change in molecular structure that could account for drug resistance in Streptomices pneumoniae, the organism that causes childhood pneumonia and claims 3.5 million lives a year, mainly in developing countries.

Australian scientists rejuvenate the immune systems of mice and humans using a common hormone

The scientists, led by Associate Professor Richard Boyd and Dr Jayne Sutherland from the Monash Immunology and Stem Cell Laboratories, have revitalised the thymus which produces the T cells required to fight infection but which shuts down from early adulthood.

Cells direct membrane traffic by channel width

For a glycerol molecule, a measly angstrom's difference in diameter is a road-closed sign: You can't squeeze through unless you are a sleek, water-molecule-sized sports car, say scientists at the University of Illinois at Urbana-Champaign.
