	Systematic fraud uncovered in mathematics publications An international team of authors led by Ilka Agricola, professor of mathematics at the University of Marburg, Germany, has investigated fraudulent practices in the publication of research results in mathematics on behalf of the German Mathematical Society (DMV) and the International Mathematical Union (IMU), documenting systematic fraud over many years.
	In the wild, chimpanzees likely ingest the equivalent of several alcoholic drinks every day The first-ever measurements of the ethanol content of fruits available to chimpanzees in their native African habitat show that the animals could easily consume the equivalent of more than two standard alcoholic drinks each day, according to researchers at the University of California, Berkeley.
	A grue jay? Rare hybrid bird identified in Texas Biologists at The University of Texas at Austin, who have reported discovering a bird that's the natural result of a green jay and a blue jay's mating, say it may be among the first examples of a hybrid animal that exists because of recent changing patterns in the climate. The two different parent species are separated by 7 million years of evolution, and their ranges didn't overlap as recently as a few decades ago.
	Evidence of cosmic impact discovered at classic Clovis archaeological sites Researchers continue to build on a body of evidence for a fragmented comet that is thought to have exploded over Earth almost 13,000 years ago, which may have had a role in the disappearance of mammoths, mastodons and most of other megafauna at that time, and in the vanishing of the Clovis culture from the archaeological record in North America.
	Culture is overtaking genetics in shaping human evolution, researchers argue Researchers at the University of Maine are theorizing that human beings may be in the midst of a major evolutionary shift—driven not by genes, but by culture.
	Ancient crop discovered in the Canary Islands thanks to archaeological DNA The lentils now grown in the Canary Islands have a history that stretches back almost 2,000 years on the site. This is shown in the very first genetic study of archaeological lentils, carried out by researchers at Linköping University and the University of Las Palmas de Gran Canaria in Spain.
	Dietary supplement found effective for skin cancer prevention The dietary supplement nicotinamide has been recommended by dermatologists for people with a history of skin cancer since 2015, when a clinical study with 386 participants showed that those who took the vitamin B3 derivative developed fewer new occurrences.
	Lymph nodes found to be key to successful cancer immunotherapy A team of researchers, led by the Peter Doherty Institute for Infection and Immunity (Doherty Institute), explored the cellular and molecular interactions revealing how lymph nodes play a crucial role in the fight against chronic infection and cancer.
	2025 Ig Physics Nobel Prize goes to perfect pasta sauce The Ig Nobel Prize honors research that first makes people laugh, then makes them think. Its 35th award ceremony possibly also makes people hungry: ISTA physicist Fabrizio Olmeda and colleagues researched the secret of a perfect cacio e pepe pasta sauce. They received the popular award for their findings on Thursday evening in Boston, U.S.
	Study finds 10% of pediatric blood cancers may stem from medical imaging radiation A study led by UC San Francisco and UC Davis has concluded that radiation from medical imaging is associated with a higher risk of blood cancers in children.
	Vitamin D3 concentrations are lowered by a common vitamin D supplement Taking vitamin D2 might lower the body's levels of the more efficient form of vitamin D, vitamin D3, according to new research from the University of Surrey, John Innes Center and Quadram Institute Bioscience. Many people take vitamin D supplements to support their bone and immune health and meet the UK government recommendation of 10 micrograms (µg) each day, especially during the winter months.
	The oldest mummies in the world may hail from southeastern Asia and date back 12,000 years Scientists have discovered what's thought to be the oldest known mummies in the world in southeastern Asia dating back up to 12,000 years.
	Model suggests gaslighters manipulate their targets by taking advantage of a learning process Gaslighting could happen to anyone who trusts the wrong person, a McGill University researcher says. Willis Klein, a Ph.D. candidate in the Department of Psychology, was part of a team from McGill and the University of Toronto that developed a new theoretical model with which to understand how manipulators are able to make their targets question their sense of reality over a period of time.
	Physicist proves unsolvability beyond one dimension for quantum Ising models By extending a proof of a physically important behavior in one-dimensional quantum spin systems to higher dimensions, a RIKEN physicist has shown in a new study that the model lacks exact solutions. The research is published in the journal Physical Review B.
	Organic beekeeping can be even more profitable than conventional methods Organic beekeeping can support healthy and productive honey bee colonies, and a new study led by researchers in Penn State's College of Agricultural Sciences has found that adopting organic honey bee colony management is not only profitable, but in some cases, it can be even more profitable than conventional management.
	Chandra finds black hole that's growing at 2.4 times the Eddington limit A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA's Chandra X-ray Observatory may help explain how some black holes can reach enormous masses relatively quickly after the Big Bang.
	Community management of protected areas in the Amazon offers 'unprecedented' results New research reveals "unprecedented" conservation results of community-based management of protected areas in the Amazon—as many face a future in which they may become increasingly degraded due to low enforcement of regulations, growing external encroachment and competition for resources.
	Aspirin halves the risk of recurrence in patients with colorectal cancer, clinical trial finds A Swedish-led research team at Karolinska Institutet and Karolinska University Hospital has shown in a new randomized clinical trial that a low dose of the well-known medicine aspirin halves the risk of recurrence after surgery in patients with colon and rectal cancer with a certain type of genetic alteration in the tumor.
	Provenance study shows 19th century looted 'Incan mummy' was actually an Aymara man In a recent study, Dr. Claudine Abegg and her colleagues analyzed the remains of a mummified cranium housed in the collections of the Museum of Cantonal Archaeology and History of Lausanne.
	Bird-like robot with novel wing system achieves self-takeoff and low-speed flight In 2021, a group of scientists from China engineered the RoboFalcon—a bird-inspired flapping-wing robot with a newly engineered mechanism made to drive bat-style morphing wings capable of flight. While this bio-inspired robot performed well at a cruising speed, it was not capable of flying at lower speeds or achieving takeoff without assistance.
