Researchers have uncovered the ancestral origins and genetic diversity of the Fulani, one of Africa’s largest pastoral populations. The study reveals a complex genetic ancestry with influences from both North and West African groups, shaped by historical migrations that have left a lasting impact on their genetic landscape.
The American artist and author Joe Brainard (1942–1994) stood out with his strikingly unique style of writing, manifested among other ways in his many years of correspondence with other well-known artists and writers. Selections from his letters have now been published in a new volume with comments and analyses by Daniel Kane, professor of American literature at Uppsala University.
On the exoplanet WASP-127b, over 500 light years away, wind speeds can reach 33,000 kilometres per hour, according to a study by an international team of scientists. This is the first time winds of this type have been detected and it has been possible thanks to an instrument partly built at Uppsala University. The study is published in Astronomy & Astrophysics.
Professor Aarti Gupta from Wageningen University and Professor Frank Biermann from Utrecht University will become Visiting Professors of Climate Change Leadership at Uppsala University. The ten-year visiting professorship, with a new professor invited each or every other year, is funded by a donation to Uppsala University by entrepreneur Niklas Zennström and his wife, Catherine Zennström.
A recent study shows that the Semliki Forest virus enters the central nervous system by first entering the cerebrospinal fluid and then binding to a specific cell type before penetrating deeper into the brain. This finding could potentially be used to develop the Semliki Forest virus as an agent for treating brain cancer. The study has been published in the journal Nature Communications.
New study: An app can help parents who are mourning the loss of a child. Parents who used the app for three months reported reduced symptoms of prolonged grief and post-traumatic stress, and also had fewer negative thoughts. Some parents thought that in future, the app should be offered early in the process of mourning. The study is published in the scholarly journal Cognitive Behaviour Therapy.
Researchers have analysed the effects of seven different hormone treatments for menopausal symptoms, and the risk of blood clots, stroke and heart attack. The risks differ depending on the active substance and how the medicine is taken. The study involves around one million women aged 50-58 and is the largest and most comprehensive study of currently prescribed hormonal substances in the world.
In an international collaboration, researchers at Uppsala University have been able to identify undigested food remains, plants and prey in the fossilised faeces of dinosaurs. These analyses of hundreds of samples provide clues about the role dinosaurs played in the ecosystem around 200 million years ago. The findings have been published in the journal Nature.
Different species of seabirds can coexist on small, isolated islands despite eating the same kind of fish. A researcher at Uppsala University has been involved in developing a mathematical model that can be used to better understand how this ecosystem works.
By exploiting the genetic variation in cancer cells, an already approved cancer drug demonstrated enhanced effects against cancer cells in specific patient groups. This is shown in a recent study from Uppsala University, published in the journal eBiomedicine. The findings suggest a potential for more individually tailored and more effective cancer therapies.
Uppsala University is contributing an important piece to the puzzle of substantially shortening the radioactive life of nuclear waste. Belgian scientists aiming to create a facility to convert long-lived radioactive fuel waste into shorter-lived waste are now enlisting the help of the FREIA Laboratory in Uppsala.
Researchers at Uppsala University and KTH Royal Institute of Technology have developed a new form of precision medicine, an antibody, with the potential to treat several types of cancer. Researchers have managed to combine three different functions in the antibody, which together strongly amplify the effect of T cells on the cancer tumour. The study has been published in Nature Communications.
All patients who have had a heart attack are typically treated using beta blockers. According to a Swedish study conducted earlier this year, this drug is unlikely to be needed for those heart patients who have a normal pumping ability. Now a sub-study at Uppsala University shows that there is also a risk that these patients will become depressed by the treatment.
Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having shrunk and the number of trees having fallen sharply during ice age cycles. These are the findings of a study jointly led by Uppsala and Helsinki Universities, published in Nature Communications.
Researchers at Uppsala University have developed a clinical model that can accurately predict the risk of hip fractures in the elderly. The model is based on analyses of data from the entire Swedish population and can identify patients at high risk, without the need to measure skeletal strength. This can speed up the process for doctors and allow patients to receive preventive treatment.
The survival rate of men with prostate cancer who had their entire prostate gland removed immediately after the tumour was detected increased by 17 percentage points compared with those who did not have treatment until the tumour began to cause symptoms. On average, they also lived more than two years longer. These are the final results of a 30-year Scandinavian study led from Uppsala University.
What are the opportunities of using AI in healthcare? And what potential risks does it entail? These issues will be discussed during the Olof Rudbeck Day on 18 October. This year’s Rudbeck Prize winner, Ulf Gyllensten, will also give a lecture on his research into gynaecological cancer.
Uppsala University will celebrate 550 years 7 October 2027. Ahead of this occasion, a jubilee campaign is being launched today: “Boundless knowledge – since 1477”, whose aim is to further strengthen the University’s research. The goal is to raise SEK 1 billion by 2027, and the campaign is already halfway towards that goal. Today’s ceremony in the Grand Auditorium will highlight this year’s donors.
A single treatment session, which includes the video game Tetris, can reduce symptoms of post-traumatic stress disorder (PTSD), shows a new study carried out with healthcare professionals working during the COVID-19 pandemic. The results are published in BMC Medicine. The study involved 164 participants, and the positive effects persisted after five weeks and even six months after treatment.
To answer this question, Linnaeus collected 643 different plant species that were then fed to horses, cows, pigs, sheep and goats. The results were carefully compiled but not analysed until now, 275 years later, when they are also published by the Linnean Society in London.
