Phys.org / Beyond the double helix: Alternative DNA conformations in ape genomes
Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular processes and of genome evolution, ...
Phys.org / Radiocarbon dating reveals Mongolia's earliest pottery predates previous estimates by 2,000 years
Following a recent study, Dr. Przemysław Bobrowski and his colleagues published new radiocarbon dates on Holocene (11,700 years ago to the present) sites located in the Tsakhiurtyn Hundi (Flint Valley) region of Mongolia. ...
Phys.org / Chemical recycling turns used silicones into pure building blocks, promising infinite reuse
A study conducted by CNRS researchers describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector's environmental impacts.
Medical Xpress / Blocking a surprising master regulator of immunity eradicates liver tumors in mice
A protein identified nearly 40 years ago for its ability to stimulate the production of red blood cells plays a surprising, critical role in dampening the immune system's response to cancer.
Phys.org / Stem cells need positional signals to drive regeneration, flatworm study reveals
Scientists at the National Cancer Institute and partnering institutions have discovered that Schmidtea polychroa, a flatworm capable of regenerating lost tissue, develops this ability progressively during early life stages. ...
Phys.org / Underground nuclear test explosions can be hidden within earthquake signals, study suggests
Could the seismic signal of an underground nuclear test explosion be "hidden" by the signal generated by a natural earthquake?
Medical Xpress / Clinical trial finds novel nutritional formula effectively treats gut microbial overgrowth
Cedars-Sinai researchers have developed a novel nutritional formula, mBiota Elemental, a palatable elemental diet (PED) that reduces the abundance of key gut microbiome taxa and improves symptoms in patients with small intestinal ...
Phys.org / Webb spots clues of a black hole at the heart of nearby galaxy M83
Astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered evidence that suggests the presence of a long-sought supermassive black hole at the heart of the nearby spiral galaxy Messier 83 (M83). This surprising ...
Phys.org / Seeing lost winters, not just rising temperatures, shakes climate indifference
Slowing human-caused climate change requires decisive action, but the slow upward creep of global temperatures contributes to apathy among people who don't experience regular climate-driven disasters, psychologists say. In ...
Medical Xpress / Legalizing cannabis edibles linked to increased adolescent use in Canada
University of Manitoba and Memorial University of Newfoundland researchers are reporting that legalization of youth-oriented cannabis edibles and extracts in Canada was associated with higher cannabis use among adolescents ...
Phys.org / Portable Raman analyzer detects hydrogen leaks from a distance
Researchers have developed a new portable Raman analyzer that can accurately measure very low concentrations of hydrogen gas in ambient air. The instrument could be useful for detecting hydrogen leaks, which pose serious ...
Medical Xpress / Young women show greater increase in past-month binge drinking than men
The sex-based differences in past-month binge drinking among young adults reversed in 2021–2023 versus 2017–2019, with higher rates emerging among women, according to a research letter published online in the Journal ...
