What has been impossible has now been shown to be possible "“ an alloy between two incompatible elements. The findings are being published in this week's edition of Proceedings of the National Academy of Science, USA. A research team led by Professor H.K. Mao from Carnegie Institution of Washington and Professor Rajeev Ahuja from UU have used high pressure experiments and theoretical calculations to study the behavior of Ce3Al under high pressure. "We were surprised to find that Cerium...

Researchers at Uppsala University can now show that what is good for one sex is not always good for the other sex. In fact, evolutionary conflicts between the two sexes cause characteristics and behaviors that are downright injurious to the opposite sex. The findings are being published in the scientific journal Current Biology.In both males and females in the animal world it is common "“ much more common that one might like to think "“ for one sex to evince characteristics and...

The indigenous Samis in Sweden's far north, once known for rounding up their reindeer on skis, have apparently traded in their skis for snowmobiles. "Everything progresses in this world. We have to hang on and follow the development," Jaavna Allas, a 30-year-old Sami reindeer herder, told AFP. "It wouldn't be possible to herd reindeer today on skis. The grazing areas are so few and far between." They have used modern techniques of rounding up reindeer for decades now, but recently have faced...

A Swedish scientist has reported the finding of a fossilized specimen that may provide new insight into how jawed vertebrates evolved. Martin Brazeau, of the Department of Physiology and Developmental Biology at Uppsala University in Sweden, said the fossil was discovered Herefordshire, UK, in the 1940s and is an estimated 415 million years old. The specimen is the first-known braincase of an Early Devonian acanthodian "“ which is possibly the earliest group of gnathostomes (jawed...

Scientists found that Tasmanian "tigers" may have gone extinct due to inbreeding and are considering resurrecting the Australian marsupials 70 years after they ceased to exist. "Our goal is to learn how to prevent endangered species from going extinct," said Webb Miller of Pennsylvania State University, who helped lead the international study. The researchers used the same method used to study the DNA from extinct woolly mammoths' hair to get a good comparison of the gene sequences from...

Sweden's Uppsala University said a copy of Isaac Newton's Philosophiae Naturalis Principia Mathematica is back with the school after its theft 40 years ago. Uppsala University officials said the book, which was given to the university by astronomer Petrus Elvius shortly after it was first published in 1687, disappeared from the school's library in the 1960s by means unknown, Swedish News Agency TT reported Monday.

Swedish researchers have identified a gene linked to increased susceptibility to the placebo effect, the mysterious capacity of some people to benefit from phony treatments with no verifiable therapeutic activity. Until now, these benefits were believed by be based on the power of suggestion. "To our knowledge, it's the first time anyone has linked a gene to the placebo effect,"  Tomas Furmark of Uppsala University in Sweden, who led the research, told New Scientist magazine. Although...

It is a well-known fact in drug trials that individuals can respond just as well to placebos, sugar pills, as to the active drug. On the other hand, it is difficult to explain why only certain people get better from placebos. A team of researchers from Uppsala University and Gothenburg University have now found gene variants that can impact the placebo effect and a mechanism in the brain that characterizes those who respond to placebos.The study, published in Journal of Neuroscience, examined...

The white horse is an icon for dignity which has had a huge impact on human culture across the world. An international team led by researchers at Uppsala University has now identified the mutation causing this spectacular trait and show that white horses carry an identical mutation that can be traced back to a common ancestor that lived thousands of years ago. The study is interesting for medical research since this mutation also enhance the risk for melanoma. The paper is published on July...
