Swedish instrument has landed on the Moon

3 January, 2019 - Institutet för rymdfysik

On January 3, 03:26 Swedish time, the Chinese Chang’E-4 spacecraft landed successfully on the far side of the Moon. The Swedish Institute of Space Physics (IRF) has developed one of the scientific instruments on board. The aim of the instrument is to study how the solar wind interacts with the lunar surface.

Our Universe: An expanding bubble in an extra dimension

27 December, 2018 - Uppsala universitet

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.

Historical genomes reveal recent changes in genetic health of eastern gorillas

27 December, 2018 - Uppsala universitet

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.

Simple method rescues stressed liver cells

21 December, 2018 - Uppsala universitet

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.

Emissions from the shipping sector can be reduced with the help of virtual fuel meters

19 December, 2018 - Linnéuniversitetet

By utilising waste heat recovery and using modern technology like machine learning to create virtual fuel meters, the shipping sector can reduce both its emissions and its fuel consumption. This is shown in a new dissertation by Fredrik Ahlgren at Kalmar maritime academy at Linnaeus University. The ships of today collect large quantities of data […]

Surgery unnecessary for many prostate cancer patients

12 December, 2018 - Uppsala universitet

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.

Biologists shed new light on an old question

12 December, 2018 - Uppsala universitet

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.

Water plumes on Europa: tasting an extraterrestrial ocean

7 December, 2018 - Institutet för rymdfysik

Computer simulations of the plumes of liquid water that stream out of Jupiter’s moon Europa show that the forthcoming space mission JUICE may offer an answer to the question as to whether the Jovian moon’s sub-surface ocean could harbour life. Hans Huybrighs comes to this conclusion in the doctoral thesis he has recently completed in collaboration with the Swedish Institute of Space Physics.

Oldest ever traces of the plague found in Falköping

6 December, 2018 - Göteborgs universitet

In a 5,000 year old grave outside Falköping, scientists have found the oldest traces of the plague bacterium’s DNA in the world. An international research team including archaeologists from the University of Gothenburg made the discovery using advanced DNA techniques. According to the researchers, this discovery may also have identified the first pandemic in history […]
