Scientists develop plastic antibody that works in bloodstream of living animal

Scientists are reporting the first evidence that a plastic antibody - an artificial version of the proteins produced by the body's immune system to recognize and fight infections and foreign substances - works in the bloodstream of a living animal. The discovery, they suggest in a report in the Journal of the American Chemical Society, is an advance toward medical use of simple plastic particles custom tailored to fight an array of troublesome "antigens."

Scientists identify the role of vitamin D in activation of T cells

Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system - T cells - will not be able to react to and fight off serious infections in the body.

Scientists create tiny RNA molecule to synthesize proteins

An extremely small RNA molecule created by a University of Colorado at Boulder team can catalyze a key reaction needed to synthesize proteins, the building blocks of life. The findings could be a substantial step toward understanding "the very origin of Earthly life," the lead researcher contends.

Chemists adopt new approach to optimise enzyme for practical applications

Engineers are unlikely to tinker with the cooling system if they want to increase the size of an engine. Yet chemists at the Max Planck Institute for Coal Research have adopted an approach similar to this in their efforts to optimise an enzyme for practical applications. They

Researchers discover chemical compound to combat malaria and bacterial diseases

Researchers report that they have discovered - and now know how to exploit - an unusual chemical reaction mechanism that allows malaria parasites and many disease-causing bacteria to survive. The research team, from the University of Illinois, also has developed the first potent inhibitor of this chemical reaction.

Tocotrienol form of vitamin E prevents neural cell death and rescues the brain after stroke injury

Blocking the function of an enzyme in the brain with a specific kind of vitamin E can prevent nerve cells from dying after a stroke, new research suggests.

Canadian Cancer Society calls on the B.C. government to ban cosmetic use of pesticides

The Canadian Cancer Society British Columbia and Yukon today called on the B.C. government to enact legislation to ban the cosmetic use of pesticides that would set a new national standard. The Society is also asking British Columbians to participate in the on-line public consultation.

Successful RNA interference to turn off multiple genes raises hope for new liver disease treatments

Researchers at MIT and Alnylam Pharmaceuticals report this week that they have successfully used RNA interference to turn off multiple genes in the livers of mice, an advance that could lead to new treatments for diseases of the liver and other organs.

Monitoring blood glucose levels with contact lenses may soon be a reality for diabetes patients

Diabetics may soon be able to wear contact lenses that continuously alert them to variations in their glucose levels by changing colours - replacing the need to routinely draw blood throughout the day.

New technology sheds light on intracellular transport

Using new technology developed in his University of Oregon lab, chemist Andrew H. Marcus and his doctoral student Eric N. Senning have captured what they describe as well-orchestrated, actin-driven, mitochondrial movement within a single cell.

Researchers develop a process to tag cancer cells

Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. Now, a study reviewed by Philip Dawson, a member of Faculty of 1000 Biology and leading authority in chemistry and cell biology, describes a novel labelling technique that uses a chemical reaction to make live cancer cells light up quickly and safely.

New discovery on DNA repair mechanism

Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA.
