Darwin was puzzled by cooperation in nature—it ran directly against natural selection and the notion of survival of the fittest. But over the past decades, evolutionary mathematicians have used game theory to better understand why mutual cooperation persists when evolution should favour self-serving cheaters. At a basic level, cooperation flourishes when the costs to cooperation are low or the benefits large. When cooperation becomes too costly, it disappears—at least in the realm of pure mathematics. Symbiotic relationships between species—like those…

The researchers were able to recreate a complete structure that includes the three key cell types in the pancreas, which previous organoids couldn’t fully mimic. Notably, the team identified a new stem cell that develops into the three cell types. These findings, published in Cell on December 2nd, could help…

Foundation for new cancer treatment strategies. A team led by researchers at the Technical University of Munich (TUM) has, for the first time, grown tumor organoids – three-dimensional miniature tumors in the laboratory – that mimic the different structures and characteristics of pancreatic cancer. The scientists investigated how the various tumor organoids react to established and novel treatments. This opens the door to the development of effective new therapies. Pancreatic cancer ranks among the most lethal cancers, with an exceptionally…

Salt pollution in freshwater is a growing global concern. Excessive salt harms plants, degrades soil, and compromises water quality. In urban areas, road salts used for de-icing during winter often wash into stormwater systems, posing health concerns and challenges for infrastructure. Specifically, salts can impact the processes like filtration and contaminate retention basins that are used to manage and treat urban stormwater runoff. Megan Rippy, assistant professor in civil and environmental engineering, is on a mission to understand how salt affects plants in…

UCalgary scientist says it’s important to determine what happened and what can be learned  Experts from the global Earth science community – including a scientist from the University of Calgary – have pieced together what happened during the massive Sikkim flood to try to help others prepare for similar disasters. On Oct. 3, 2023, a multi-hazard cascade in the Sikkim Himalaya, India, was triggered by a permanently frozen (permafrost) lateral moraine – debris from erosion along a glacier – collapsing…

Potential new therapy for childhood brain cancer is effective in infiltrating, killing tumor cells in preclinical models in mice  Brain cancer is the second-leading cause of death in children in the developed world. For the children who survive, standard treatments have long-term impacts on their development and quality of life, particularly in small children and infants. Research out of Emory University and QIMR Berghofer Medical Research Institute in Queensland, Australia, has shown that a potential new targeted therapy for childhood brain cancer is…

A new international study highlights the severity of climate change impacts across African mountains, how farmers are adapting, and the barriers they face – findings relevant to people living in mountain regions around the world. “Mountains are the sentinels of climate change,” said Julia Klein, a Colorado State University professor of ecosystem science and sustainability and co-author of the study. “Like the Arctic, some of the first extreme changes we’re seeing are happening in mountains, from glaciers melting to extreme…

Previous exposures to older flu strains prime the immune system to produce antibodies against H5N1, and children would likely benefit the most from H5N1 vaccinations Prior exposures to specific types of seasonal influenza viruses promote cross-reactive immunity against the H5N1 avian influenza virus, according to new research from the Perelman School of Medicine at the University of Pennsylvania. Older adults who were exposed to seasonal flu viruses that circulated prior to 1968 were found to be more likely to have…

A small deletion in a gene on the X-chromosome lies behind the fiery coats of ginger tabbies and the splotchy orange patches of calicos and tortoiseshell cats. Fukuoka, Japan – From Tama, Japan’s most famous stationmaster calico cat, to the lasagna-loving, ginger Garfield, cats with orange fur are both cultural icons and beloved pets. But their distinctive color comes with a genetic twist-most orange tabbies are male, while calicos and tortoiseshells are nearly always female. This pattern points to an…

SAN ANTONIO — August 18, 2025 — A team led by Southwest Research Institute (SwRI) has confirmed decades-old theoretical models of magnetic reconnection — the explosive process that releases stored magnetic energy and powers solar flares, coronal mass ejections, and other space weather events.

Researchers find two new leads for anti-anthrax drugs.

As fears over bioterrorism attacks spiral, researchers are making progress towards better anthrax drugs – but these are unlikely to reach the drugstore soon.

Of ten confirmed anthrax cases in the United States by Monday, four have been of the severe, inhaled form against which antibiotics often fail. By the time drugs destroy the bacteria responsible, Bacillus anthracis, the organisms have released enough lethal toxin t

A balanced portfolio of programs could mean a faster quantum computer.

Strategies from the world of finance could help get the best out of quantum computers, say US researchers 1 . The right portfolio of programs could solve a problem many times faster than a single strategem.

Quantum computers – purely hypothetical as yet – would be fast, but you could never be sure whether a program was going to work or not. You would have to keep running the program until

Astronomers from the University of Pennsylvania, in collaboration with an international team of researchers, have made the first direct detection and measurement of the properties of a dark matter object in the Milky Way.
