(British Medical Journal) – Clinicians' reluctance to discuss possible harms of anal sex is letting down a generation of young women who are unaware of the risks, warn researchers in The BMJ today.
Surgeons Tabitha Gana and Lesley Hunt argue that as anal intercourse becomes more common amongst heterosexual couples, failure to discuss it "exposes women to missed diagnoses, futile treatments, and further harm arising from a lack of medical advice."
They say healthcare professionals, particularly those in general practice,...
In a new University of California, Irvine-led study, researchers define how the circadian clock influences cell growth, metabolism, and tumour progression. Their research also reveals how disruption of the circadian clock affects genome stability and mutations that can further drive critical tumour-promoting pathways in the intestine.
The study, titled, "Disruption of the Circadian Clock drives Apc Loss of Heterozygosity to Accelerate Colorectal Cancer", was published today in Science Advances.
Researchers found that both genetic disruption and environmental...
Caffeine jump-starts your day and puts a bounce in your step. It can help you focus, improve your mood and maybe even help you live longer.
But how much is too much?
Caffeine, a natural stimulant, can be found in a variety of foods, such as coffee beans, tea leaves, cacao beans, guarana berries, and yerba maté leaves. It also can be synthetically created and added to beverages such as soda and energy drinks. Research shows that...
The Treasury Department has imposed sanctions on virtual currency mixer Tornado Cash, which has allegedly helped to launder more than $7 billion worth of virtual currency since its creation in 2019.
Treasury's Office of Foreign Assets Control says Tornado Cash's systems were used, among other things, to launder more than $96 million drawn from the June Harmony blockchain bridge theft and August Nomad crypto firm heist, Tech Xplore reports.
Mixing services combine various digital assets, including...
In what's reported as a world-first achievement, biologists have grown mouse embryo models in the lab without the need for fertilized eggs, embryos, or even a mouse – using only stem cells and a special incubator.
This achievement, published in the journal Cell by a team led by researchers from the Weizmann Institute of Science in Israel, is a very sophisticated model of what happens during early mouse embryo development – in the stage just after implantation.
This is a crucial stage: in...
Researchers at the National Renewable Energy Laboratory (NREL) ran hundreds of millions of simulations to gauge the contribution buildings make to gross grid value and created a publicly available dataset for others to use.
It is the first study to estimate the gross value (including capacity, energy, and ancillary service values) of generic building flexibility in future power systems projected for the contiguous United States using computer modeling. Building flexibility refers to a building's capability...
The U.S. has urged Moscow to accept a deal to free basketball player Brittney Griner, who has been sentenced to nine years in a Russian prison, the BBC reports.
The double Olympic winner was convicted of possessing and smuggling drugs after admitting to possessing cannabis oil.
White House national security spokesman John Kirby said the U.S. offer was "a serious proposal," but gave no details.
U.S. media reports suggest Washington is offering a prisoner swap involving a Russian arms...
As satellites crawl across the sky, they reflect light from the sun back down to Earth, especially during the first few hours after sunset and the first few hours before sunrise. As more companies launch networks of satellites into low-Earth orbit, a clear view of the night sky is becoming rarer. Astronomers, in particular, are trying to find ways to adapt, writes Mikayla Mace Kelley of the University of Arizona (U of A).
With that in mind, a...
The traditional idea of symbiosis — long-term interactions between two organisms — is that the participants mutually benefit each other. However, researchers have debated whether the interests of the symbionts always line up with the hosts they inhabit, or whether genes that benefit symbionts might come at the expense of their hosts. A new study investigates this question through genomic sequencing and infecting plant hosts with their microbial symbionts, writes Ananya Sen of the University of...
The first ship carrying grain has left a Ukrainian port under a landmark deal with Russia, the BBC reports.
Turkish and Ukrainian officials say the ship left the southern port of Odesa early on Monday morning local time.
Russia has been blockading Ukrainian ports since February, but the two sides made a deal to resume shipments.
It is hoped the agreement will ease the global food crisis and lower the price of grain.
Turkey said the Sierra Leone-flagged...
