Ancient steppe herders brought higher risk of MS to northern Europe
Study of ancient DNA shows bronze age Yamnaya people spread gene variants that carry increased risk of multiple sclerosisAncient DNA helps explain why northern Europeans have a higher risk of multiple sclerosis than other ancestries: the disease is a genetic legacy of horseback-riding cattle herders who swept into the region about 5,000 years ago.The findings come from a huge project to compare modern DNA with that culled from ancient humans ’ teeth and bones – allowing scientists to trace prehistoric migration and disease-linked genes that tagged along.Continue reading...

I discovered a tree kangaroo that had only been seen once – by the man who shot it in 1928
I want people to be excited about the animals I find and get them involved in conservationI am a British tourist, and I spend my holidays searching for species that are believed to be extinct. On my last trip to Papua New Guinea in 2022, I found a Louisiade pitta bird, which had been the focus of failed professional expeditions for years. It hadn ’t been seen alive since 1898.We went around playing recordings of a related pitta, which sounds a bit like achicken being strangled, until we received a reply. Imagine if you went around a haunted house rattling chains and then you heard a ghost rattling them back – that is w...

Radiation oncology groups unite to reform Medicare payments
Four U.S. physician groups representing radiation oncology have partnered to try to reform Medicare payments and expand patient access to high-quality care.
Leaders of the American College of Radiation Oncology (ACRO), the American College of Radiology (ACR), the American Society for Radiation Oncology (ASTRO), and the American Society of Clinical Oncology (ASCO) stressed the need for a unified approach to create meaningful change on this critical issue, ASTRO said in a January 9 news release.
Medicare payments for radiation therapy services have been cut by 23% since 2013 and this threatens patient access to cancer care...

Smart skin bacteria are able to secrete and produce molecules to treat acne
International research led by the Translational Synthetic Biology Laboratory of the Department of Medicine and Life Sciences (MELIS) at Pompeu Fabra University has succeeded in efficiently engineering Cutibacterium acnes -a type of skin bacterium- to produce and secrete a therapeutic molecule suitable for treating acne symptoms. The engineered bacterium has been validated in skin cell lines and its delivery has been validated in mice. (Source: World Pharma News)

VR test differentiates between novice, expert ultrasound users
An immersive virtual reality (VR)-based test can distinguish between operators with varying levels of thoracic ultrasound skill, a Danish study published January 6 in Ultrasound in Medicine & Biology found.
Researchers led by Anders Nielsen from Odense University Hospital in Svendborg found that between novice, intermediate, and expert ultrasound users, the experts had the highest test scores while the novice users had the lowest scores.
“This [test] enables a standardized, objective, and evidence-based approach to assessment of thoracic ultrasound skills,” Nielsen and co-authors wrote.
With ultrasound being a user-...

Massive study of dog aging likely to lose funding
Scientists who study aging are howling about the possible demise of one of the field’s biggest studies, the Dog Aging Project. The effort has been probing cognitive and physical aspects of aging in about 50,000 dogs and is running a clinical trial to test a drug that may boost the animals’ longevity. But organizers say the project will probably lose funding this year from the National Institute on Aging (NIA), which has furnished at least 90% of its annual budget, now about $7 million.
“It is a big loss if this project in dogs does not continue,” says gerontologist João Pedro de Magalhães of the University ...

A snake ’s teeth predict how fast it will strike
SEATTLE—
The open, fanged mouth of a snake poised to strike is terrifying to most people. But William Ryerson is not like most people. Over the past few years, this herpetologist at the Cornell University College of Veterinary Medicine has peered into those mouths, analyzing the teeth’s shape, position, and size, and filmed them in action. This week at the annual meeting of the Society for Integrative and Comparative Biology, he reported that
these factors can be used to predict the speed and direction of a snake’s strike

“It’s cool to see this link between form and function,” says Lisa W...

Ahead, ablackbird lands beside the footpath and begins flinging aside dead leaves, with the irascible air of a gardener discovering fly-tipped rubbish on their lawn.
