Sweet insight: Discovery could speed drug development
The surface of cells and many biologically active molecules are studded with sugar structures that are not used to store energy, but rather are involved in communication, immunity and inflammation. In a similar manner, sugars attached to drugs can enhance, change or neutralize their effects, says Jon Thorson , a professor of pharmaceutical sciences at the University of Wisconsin-Madison School of Pharmacy.

Cells derived from pluripotent stem cells may pose challenges for clinical use, research
UCLA researchers have found that three types of cells derived from human embryonic stem (hES) cells and from induced pluripotent stem (iPS) cells are similar to each other, but they are far more developmentally immature than those same cell types taken directly from human tissue. In fact, the progeny of these hES and iPS cells are much more similar to cells found within the first two months of fetal development than anything later, according to the scientists from UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research.

Micro-organisms are "invisible" to the immune system
That micro-organisms have a great capacity to vary their surface structure is well known. It is one of the reasons why it is so difficult to develop vaccines against HIV and malaria, and why new influenza vaccines have to be produced every year. But it seems that these micro-organisms are also able to completely avoid activating a strong immune response in the person attacked.

Wrens eavesdrop on the neighbours
Superb fairy-wrens eavesdrop, learn to understand and react to the danger calls of other bird species that live nearby, according to new research published today in the Proceedings of the Royal Society B. Associate Professor Robert Magrath and Thomas Bennett from the Research School of Biology at The Australian National University made the discovery by playing recordings of miner-bird danger calls to fairy-wrens and observed the wrens fleeing to safety.

Stress in early life reduces life expectancy - and that of partners
A new study from the University of Glasgow, published today in the Proceedings of the Royal Society B: Biological Sciences, suggests that our expectancy is likely to be strongly affected by how much stress we were exposed to early in our lives. And worse still, the study also shows that early life stress experienced by our mates could also be affecting how long we are likely to live.

Parasite uses the power of sexual attraction to trick rats into becoming cat food
Could it be love? Rats infected with the parasite Toxoplasma seem to lose their fear of cats – or at least cat urine. Now Stanford researchers have discovered that the brains of those infected, fearless male rats show activity in the region that normally triggers a mating response when they meet a female rat.

Mosquitoes can’t spot a spermless mate
A female mosquito cannot tell if the male that she has mated with is fertile or 'spermless' and unable to fertilise her eggs, according to a new study from scientists at Imperial College London. The research, published today in the journal Proceedings of the National Academy of Sciences , could help scientists in their mission to prevent the spread of malaria by interfering with the mosquitoes' ability to reproduce.

Mutations Not Inherited From Parents Cause More Than Half the Cases of Schizophrenia
Many cases of schizophrenia occur in families with no history of the disease. Rare protein-altering genetic mutations contribute to these cases. Researchers expect to find perhaps hundreds more of such mutations—a necessary step toward understanding how the disease develops. Columbia University Medical Center researchers have shown that new, or "de novo," protein-altering mutations—genetic errors that are present in patients but not in their parents—play a role in more than 50 percent of "sporadic" —i.e., not hereditary—cases of schizophrenia.

Roadblocking cancer: How combo therapies can overcome drug resistance in melanoma
About 50 to 60 percent of patients with melanoma have a mutation in the BRAF gene that drives the growth of their cancer. In clinical trials, most of these patients have responded remarkably well to two novel agents that inhibit the gene, but unfortunately, the response is almost always limited in duration, as the cancer develops a resistance to the drugs.
