 Male Birth Control Treatment Could Focus on Sperm Proteins, Not Hormones A male form of "the pill" has stymied researchers for years, but now a new study finds that such male birth control may be possible by blocking a single protein in sperm cells. In a mouse study, the researchers focused on a protein called calcineurin, which is found in the sperm-producing cells of the testes as well as other cells in the body. The researchers genetically engineered mice so that they lacked a gene that makes part of the calcineurin protein but is activatedonly in sperm-producing cells.

The study, which is planned for next year, was just granted approval by the Health Research Authority, part of the U.K.'s Department of Health, which oversees research on humans. It will include women ages 25 to 38 who don't have a uterus, either because they were born without one, or because they had the organ removed as treatment for a serious illness, such as cervical cancer.

Why Perceptions of Attractiveness Vary If you ask these questions to a group of people, they may have different answers, and a new study hints at why: Your perception of other people's attractiveness is mainly the result of your own experiences. In the study of twins, researchers found that a person's environment plays a bigger role than genes in shaping whom they find attractive. The idea that beauty is in the eye of the beholder has been around for a long time, said Laura Germine, a psychiatric researcher at Massachusetts General Hospital in Boston and lead author of the new study.

Conditional approval, if granted, would allow Cardiff-based Cell Therapy to start selling its Heartcel product for regenerating damaged areas of heart while continuing to collect further clinical evidence about its effectiveness. The European Medicines Agency (EMA) is keen to test such conditional approval procedures as part of a drive to evaluate promising life-saving treatments more swiftly than in the past.

Irish-born Campbell and Japanese Omura won half of the prize for discovering a new drug, avermectin, that has helped the battle against river blindness and lymphatic filariasis, as well as showing effectiveness against other parasitic diseases. The Chinese scientist Youyou Tu was awarded the other half of the prize for discovering artemisinin, a drug that has significantly reduced the mortality rates for patients suffering from malaria.

Edinburgh-based Celtic Renewables developed its process of producing biobutanol at industrial scale in Belgium and was recently awarded a £11 million ($16.7 million USD) grant by the British government to build a bespoke facility of its own in central Scotland. Professor Martin Tangney founded Celtic Renewables in 2012 as a spin-off company from Edinburgh Napier University.

Researchers surveyed more than 1,000 middle schoolers in Southern California about their use of alcohol and marijuana, and their views of these drugs. Then, when the kids were 16 years old and in high school, they were asked how often they had driven a vehicle after drinking alcohol or using drugs (also called "driving under the influence"), and how often they had ridden in a car with someone who was driving under the influence.

This matters because feral cats (domesticated cats that live in the wild) are major predators for native birds and small mammals the world over. But feral cats are hard to control, because they behave very differently depending on where they live, said Andrew Bengsen, a research scientist in the New South Wales Department of Primary Industries Vertebrate Pest Research Unit in Australia, and lead author of the new study.

Researchers found that 9 percent of children whose families participated in a year-long therapy intervention developed an anxiety disorder during the study period, whereas 21 percent of children in a control group, who received a pamphlet about anxiety disorders, developed an anxiety disorder during the study. The study included 136 families that had at least one parent with an anxiety disorder, and at least one child between ages 6 and 13.

Half of the Nobel Prize was awarded jointly to William C. Campbell and Satoshi ?mura for discovering a new treatment for infections caused by roundworm parasites. The other half went to Youyou Tu for discovering a drug to fight malaria, the mosquito-transmitted disease that takes some 450,000 lives each year globally, according to the Nobel Foundation.
