At the age of 20, many people still don t know exactly what they want to do with their lives. The same seems to apply to sexual orientation. This, at least, is a result of a survey of almost 7,000 American students. They were interviewed three times about their sexual preferences between 1995 and 2009: as teenagers, in their early twenties and in their late twenties. Especially for young women, the early twenties are a sexually dynamic time. In contrast to young men, out of whom 90 percent said that they were heterosexual, only two thirds of young women would place themselves in this category. Ten percent felt they were mostly heterosexual and 7.5 percent epressed a clear interest in both sexes.

How do you manage the trick of feeding school children better and at a lower cost? How do you count the number of mangoes on your farm so that you get a fair price? And what’s a clever-but-cheap way for a farmer to cut down his irrigation bill?

It might sound like a sci-fi fantasy, but scientists are determined that one day we ll be able to 3D-print vital organs, like the heart, kidney or liver, to use in transplants. Cardiovascular disease and stroke kill more people globally than anything else, according to the World Health Organization, and synthetic organs could help enormously in overcoming issues of organ shortage and the risks of patients bodies rejecting them.

Compared with dogs, the human sense of smell is pathetic: The animals smell 10,000 to 100,000 times better than we do. They can sniff out not only drugs and explosives, but also cancer. However, in previous studies, the accuracy of the animals left something to be desired. There s a new US study out that claims an amazingly high hit rate. Three beagles are said to have identified 96.7 percent of lung cancer in blood samples. The dogs detected the healthy control in 97.5 percent of the cases. Only a fourth dog in the group, Snuggles, had no desire at all for the job.

For a long time it has been assumed that it is only a woman s age that matters when it comes to having children, as her fertility begins to decline in her 30s and 40s and she then reaches menopause in her 40s or 50s. However, research over the past few years has illuminated that a father s age matters, too, when it comes to both fertility and a child s development. A recent study in the journal Biological Psychiatryreaffirms the link between advanced paternal age and schizophrenia and reveals that specifically the risk of early-onset schizophrenia increases in the offspring of older fathers. This severe form of schizophrenia occurs before the age of 18 and is associated with more genetic abnormalities.
