An isolated population of honeybees in South Africa, the Cape bees, has evolved a strategy to reproduce without males. A team of researchers at Uppsala University and in South Africa has sequenced the entire genomes of a sample of Cape bees and compared them with other populations of honeybees to find out the genetic mechanisms behind their asexual reproduction.
In a new study, published in Science, researchers from Uppsala University found that larval fish exposed to microplastic particles during development displayed changed behaviors and stunted growth which lead to greatly increased mortality rates. Larval perch that had access to microplastic particles only ate plastic and ignored their natural food source of free-swimming zooplankton.
Men with blood cells that do not carry the Y chromosome are at greater risk of being diagnosed with Alzheimer’s disease. This is in addition to an increased risk of death from other causes, including many cancers. These new findings by researchers at Uppsala University could lead to a simple test to identify those at risk of developing Alzheimer’s disease.
Uppsala physicists have in an international collaboration developed a new method for creating laser pulses which are shorter, have much higher intensity and cover the THz frequency range better than current sources. The study is published today in the authoritative journal Nature Photonics and is of great importance to materials research.
A simple paper sheet made by scientists at Uppsala University can improve the quality of life for millions of people by removing resistant viruses from water. The sheet, made of cellulose nanofibers, is called the mille-feuille filter as it has a unique layered internal architecture resembling that of the French puff pastry mille-feuille (Eng. thousand leaves).
A new study from Uppsala University shows that compared to non-shift workers, shift workers needed more time to complete a test that is frequently used by physicians to screen for cognitive impairment. However, those who had quit shift work more than five years ago completed the test just as quick as the non-shift workers. The findings are published in the journal Neurobiology of Aging.
Canine Degenerative Myelopathy (DM) is a neurodegenerative disease in dogs with similarities to ALS in humans. Scientists at Uppsala University, SciLifeLab, the Broad Institute of MIT and Harvard, and the University of Missouri, have discovered a modifier gene that affects the risk of developing DM in Pembroke Welsh Corgis. The study is published in PNAS this week.
In just a few decades, the number of overweight and obese adults and children in the world has reached alarming levels, not least in low-income countries. This year, Uppsala Health Summit is taking place in conjunction with World Obesity Day: 11-12 October 2016. International experts on child obesity will gather to discuss countermeasures with industry, policy makers and society.
Same-sex sexual behavior is common in animals but puzzles evolutionary biologists since it doesn’t carry the same obvious benefits as heterosexual courtship behavior that leads to mating and production of offspring. A study from Uppsala University sheds new light on the pervasiveness of same-sex sexual behavior in the animal kingdom.
Brain tumours in dogs are strikingly similar to their human tumour counterparts. In a recent study in the journal PLOS Genetics, researchers at Uppsala University and Swedish University of Agricultural Sciences have used genetic analyses in different dog breeds to identify genes that could have a role in the development of brain tumours in both dogs and human.
In a world first study researchers have found that coral bleaching and death can have dramatic repercussions for how small reef fish learn about and avoid predators. The new results are published in the journal Proceedings of the Royal Society B.
Researchers and doctors at Uppsala University, along with Swedish and international collaboration partners, have found gene variants that predict the risk of a serious adverse reaction to drugs used for the treatment of hyperthyroidism. The results are published in The Lancet Diabetes & Endocrinology.
