Human cells can change job to fight diabetes

Human cells can change job to fight diabetes

Traditional cell biology textbooks say that most cells can only differentiate to the same cell type, with the same function. It seems that some of these textbooks need to be rewritten, thanks to the new results by researchers at the University of Bergen and their international partners at Université de Genève (UNIGE), Harvard Medical School, Universiteit Leiden and the Oregon Stem Cell Center (OHSU).

Cannabis use in teens raises risk of depression in young adults | University of Oxford

Cannabis is the most commonly used recreational drug by teenagers worldwide. In Canada, among youth aged 15 to 19 years, the rate of past-year cannabis use is 20.6%, while in England, 4% of adolescents aged 11 to 15 years used cannabis in the last month. While there has been a lot of focus on the role of cannabis use in psychosis, there has been less attention on whether cannabis use is associated with an increased risk of common mental health disorders, such as depression and anxiety.

New drug raises hopes of reversing memory loss in old age

New drug raises hopes of reversing memory loss in old age

An experimental drug that bolsters ailing brain cells has raised hopes of a treatment for memory loss, poor decision making and other mental impairments that often strike in old age. The drug could be taken as a daily pill by over-55s if clinical trials, which are expected to start within two years, show that the medicine is safe and effective at preventing memory lapses. Tests in the lab showed that old animals had far better memory skills half an hour after receiving the drug. After two months on the treatment, brain cells which had shrunk in the animals had grown back, scientists found.

Female human body blocks weak sperm, scientists find

Female human body blocks weak sperm, scientists find

For millions of sperm it is the end of the road. Scientists have found evidence that the female reproductive tract is shaped in such a way that stops poor swimmers from reaching their goal. Researchers used small-scale models and computer simulations to show that pinch points that behave like gates along the sperm’s arduous path from cervix to egg allow only the fastest ones through. Tests with sperm from men and bulls revealed that the strongest swimmers were most likely to make it through the tight spots, known as “strictures”, while weaker ones were caught in oncoming currents that propelled them backwards when they got too close.
