A study from Uppsala University has found that whether you store your fat around the trunk or in other parts of your body is highly influenced by genetic factors and that this effect is present predominantly in women and to a much lower extent in men. In the study, published in Nature Communications, the researchers measured how fat was distributed in nearly 360,000 voluntary participants.

Uppsala University researchers have devised a new model for the Universe – one that may solve the enigma of dark energy. Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.

The critically endangered Grauer’s gorilla has recently lost genetic diversity and has experienced an increase in harmful mutations. These conclusions were reached by an international team of researchers who sequenced eleven genomes from eastern gorilla specimens collected up to 100 years ago, and compared these with genomes from present-day individuals. Results are published in Current Biology.

Isolated human hepatocytes are essential tools in preclinical and clinical liver research, but cell quality is highly variable. Now, researchers from Uppsala University have devised a simple protocol that improves hepatocyte quality and enables cells from a wider quality spectrum to be used in standard and advanced cell culture. The findings are published in Archives of Toxicology.

For nearly 100 years biologists have argued about how exactly natural selection can possibly work. If nature selects the individuals with the best genes then why aren’t all organisms the same? Recent findings made at Uppsala University suggest that the answer could be sex.

Otherwise healthy men with advanced prostate cancer may benefit greatly from surgery, but many with this diagnosis have no need for it. These conclusions were reached by researchers after following a large group of Scandinavian men with prostate cancer for 29 years. The results are now published in The New England Journal of Medicine.

The White-browed Shortwing has been considered to be a single species. But now the mainland and Taiwan Island populations have been studied by an international team of researchers, led by Uppsala University. They analysed DNA, plumages, structure, songs and geographical distributions, and concluded that the continental and Taiwanese populations are actually three rather than one species.

Using DNA sequences for 402 of the 452 species of the world’s “babblers”, an international team from China, Sweden, Denmark, Switzerland and the USA have analysed the evolutionary relationships among these species. Many of these species have not previously been studied using genetic methods, and this is by far the most comprehensive analysis of this group of birds to date.

During the Triassic period mammal-like reptiles called therapsids co-existed with ancestors to dinosaurs, crocodiles, mammals, pterosaurs, turtles, frogs, and lizards. Researchers at Uppsala University in Sweden, together with colleagues in Poland, have discovered fossils from a new genus of gigantic dicynodont. The new species Lisowicia bojani is described in the journal Science.

When deciding not to resuscitate patients in cardiac arrest, ethical issues arise. Nurses and physicians conflicting perspectives often cause frustration. In a new doctoral thesis from Uppsala University, Mona Pettersson examines clinical and ethical perspectives on “DNR orders” in cancer care.
