Phys.org / Why chickens come in so many colors, and what one gene reveals about evolution
From snow white and jet black to golden brown, domestic chickens display a wider range of plumage colors than almost any other livestock species. A new international study, with researchers from Leipzig University playing ...
Medical Xpress / Q&A: Researcher provides insights into melanoma prognosis
Each year, more than 6,000 Swedes are diagnosed with melanoma. Melanoma is a form of skin cancer that, if detected late, can be fatal. Not all melanomas behave in the same way. A new doctoral thesis from Karolinska Institutet ...
Medical Xpress / Early heart changes may predict cancer years before diagnosis, long-term study suggests
A new study led by UCLA Health physician-scientists suggests that subtle changes in heart structure and function may signal an increased risk of developing certain cancers years later. The findings, published in the Journal ...
Medical Xpress / Women's thyroid cancer risk may be linked to reproductive lifespan and hormone therapy
Longer lifetime exposure to female hormones may increase the risk of thyroid cancer in women, according to a study presented at ENDO 2026, the Endocrine Society's annual meeting in Chicago. The research suggests reproductive ...
Medical Xpress / A common newborn procedure faces new scrutiny as evidence undercuts one widely blamed cause of breastfeeding trouble
A joint study by the University of Oulu and Oulu University Hospital suggests that a newborn's upper lip frenulum is unlikely to be a major cause of breastfeeding difficulties. The study, published in JAMA Network Open, followed ...
Phys.org / Ancient DNA from Tuscan wells reveals origins of modern wine
Scientists analyzing 2,000-year-old grape seeds from ancient wells in Tuscany have mapped the most extensive genetic history of ancient grapevines recovered from a single site.
Phys.org / Brains update sensory predictions through single timing hub, electric fish study finds
In the split second after you hear a noise, your brain is already making a potentially life-or-death deduction: Did I do that, or did something else? Our nervous systems answer this question using something called corollary ...
Phys.org / Genomes from Oceania offer new clues to human evolution
A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representation in genomics research. Despite harboring ...
Phys.org / Maya altar and offerings at abandoned Belize sites highlight enduring ritual activities
Archaeologists excavating Maya sites at Kaxil Uinik and Ayiin Winik in Belize have discovered the first reported Late Postclassic altar in the region, along with additional evidence that Postclassic Maya people continued ...
Science X / Will Earth truly cool down after net-zero, or are we locked into millennia of Anthropocene heat?
We imagine that if global emissions are reduced, the problem will sort itself out. It actually takes much more time than we can imagine—sometimes hundreds or even thousands of years. We have entered a very crucial stage called ...
Phys.org / Wasp spider reveals rapid genetic adaptation during decades-long march into northern Europe
It has taken only a few decades: The wasp spider (Argiope bruennichi) has expanded its range from the Mediterranean region to northern Europe—even as far as southern Finland. In doing so, it has adapted genetically much faster ...
Tech Xplore / Monolayer WSe₂ unlocks high-performance p-type transistors that could change how future chips balance speed and power
Transistors, small devices that can amplify or switch electrical signals, are central components of all modern computer chips and digital devices. There are two main types of transistors, known as n-type and p-type transistors.
