Researchers in Bonn decipher how the human body controls a widespread viral infection The Epstein-Barr virus (EBV) can cause certain types of cancer or autoimmune diseases, but how the body controls this common viral infection is largely unknown. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now identified genetic and non-genetic factors that help the body fight EBV.

An international research team, with participation of the University of Bern, has conducted the world's first comprehensive genetic study of cancer in domestic cats. The study shows that some of the genetic changes in cat tumors closely resemble those found in human cancers. These parallels open up new perspectives for developing targeted cancer therapies, particularly for breast cancer.

UCalgary scientist says research could be used for conservation and herd management Strong social networking plays an important role in human relationships. New research on female red deer shows that those bonds are also crucial for their reproductive success and survival. The study, which looked at more than 40 years of data for free-ranging adult female red deer on the Isle of Rum in Scotland, was recently published in Royal Society Open Science .

A nanodevice developed at EPFL produces an autonomous, stable current from evaporating saltwater by using heat and light to control the movement of ions and electrons. In 2024, researchers in the Laboratory of Nanoscience for Energy Technology ( LNET ) in EPFL's School of Engineering reported a platform for studying the hydrovoltaic (HV) effect - a phenomenon that allows electricity to be harvested when fluid is passed over the charged surface of a nanodevice.

Species numbers alone do not fully capture how ecosystems are changing. In a global study led by researchers from the German Centre for Integrative Biodiversity Research (iDiv), the Martin Luther University Halle-Wittenberg (MLU), and the Friedrich Schiller University Jena, scientists analysed long-term data from nearly 15,000 marine and freshwater fish communities.

A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a significant step in the treatment of neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. Dr. Travis Craddock, a professor of biology at the University of Waterloo and Canada Research Chair in Quantum Neurobiology, led the research team that is the first to use weak magnetic fields and isotopes to change the structure of cells.

A look into Earth's history shows that the ice-sheet melt temporarily intensified Southern Ocean stratification During the last deglaciations, the Antarctic ice-sheet melting temporary intensified the stratification of the Southern Ocean, thereby slowing global ocean circulation. The results also indicate that wind dynamics maintained deep-sea ventilation despite freshwater inflow.

A research team at the University of Würzburg has deciphered another aspect of poxviral gene activation. The study reveals a unique viral mechanism: a molecular ring anchors the viral copying machine to the DNA. Compared to other organisms, viruses have very small genomes. Their genetic material is not sufficient to maintain their own metabolism, produce proteins or reproduce independently.

A new multinational study from the INTERCOVID Consortium, led by researchers from the University of Oxford, has found that COVID-19 vaccination during pregnancy, particularly when combined with a booster dose, significantly reduces the risk of preeclampsia, a serious and potentially life-threatening pregnancy complication.

Experimental approach shows early promise; aim is more effective immunotherapy with fewer side effects Scientists at McGill University and the Rosalind and Morris Goodman Cancer Institute have developed a new way to deliver cancer immunotherapy that caused fewer side effects compared to standard treatment in a preclinical study.

New research shows a single year of warmer-than-average Arctic temperatures can cause malnutrition in Arctic seals, intensifying risks to Inuit food security and northern ecosystems already under pressure from environmental toxins, warn Simon Fraser researchers. The SFU study found Arctic ringed seals are struggling to clear persistent contaminants and banned pesticides from their bodies - a long-term health risk made worse when climate-driven changes to sea ice and temperatures limit their access to nutrient-rich food.

New astronomical find is 8.5 billion years old and reshapes our understanding of early cosmic evolution Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams that trail behind them.

A study led by the University of Valladolid (Uva) and the State Meteorological Agency (AEMET), with the participation of the Desertification Research Center (CIDE), a joint center of the University o

Climate New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning Circulation (AMOC), causing temperatures to fluctuate between hot and cold for thousands of years. The study contributes missing pieces to our understanding of what could cause Northern Europe's radiator to shut down.

Some bacteria are miniature masters of navigation: A built-in "compass" made of magnetic nanoparticles helps them to reliably find the optimal habitat. Researchers at the University of Basel have now unlocked the magnetic properties of individual bacteria - an important step toward harnessing the potential for technology, environmental research and medical applications.

If you, as a user, want to protect your privacy, it is not enough to ask tech companies to delete your data. What the companies' AI models have learned from that data must also be unlearned. Researchers from SDU Applied AI and Data Science have now found a way to do this without weakening model performance.

Researchers have found more evidence that microplastics are impacting freshwater wildlife in different countries around the world. A new study, led by the University of Glasgow and published in the journal Environmental Research, documents the presence of microplastics in the droppings of freshwater birds nesting in different sites in Europe.

New research reveals that, in space, certain heart muscles are put to the test by weightlessness. In just a few months, they atrophy. The consequences of this process, which takes decades on Earth, on astronauts' health remain to be assessed. On a positive note, these results could advance our understanding of certain mechanisms behind mitral valve insufficiency.

ISTA physicists explain the exceptional energy-harvesting efficiency of perovskites Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at converting solar energy into electricity. Their efficiency is approaching that of silicon-based solar cells, the industry standard.

For decades, scientists have searched the skies for signs of extraterrestrial technology. A study from EPFL asks a sharp question: if alien signals have already reached Earth without us noticing, what should we realistically expect to detect today? Since the first SETI experiment in 1960, astronomers have scanned the Milky Way for signs of advanced extraterrestrial civilizations.
