Researchers describe a novel form of gene regulation that is altered in bladder cancer, leading to the boosting of a gene pathway that helps the cancer cells survive during rapid growth. The work focuses on a 22-base fragment of transfer RNA, tRF-3b, which is modified by the enzyme complex TRMT6/61A. In bladder cancer, the levels of TRMT6/61A -- a methyltransferase -- are elevated. The methylation...

Global warming can result in the spread of peatland vegetation in the Arctic. An international research group has discovered signs of 'proto-peat', which may be the beginning of new peatlands.
Oomycetes, also known as water moulds, are pathogenic microorganisms that resemble fungi and are responsible for a group of diseases affecting several plant species. To reach and infect plants, the spores swim to their target. Physicists and biologists have now precisely measured the movement of each flagellum while a zoospore follows a linear trajectory and when it is turning.
New research shows that hypoxia can activate the same group of immune cells that cause inflammation during asthma attacks.
Epigenetic drugs that have shown promise in cancer trials significantly reduce scarring in the cells of patients with scleroderma, a new study shows. Results reveal that drugs that inhibit BRD4, known to play a role in cancer, also affect fibrosis in scleroderma. Researchers tested BRD4 inhibitors on the skin fibroblasts of scleroderma patients and in mouse models of skin fibrosis, finding that...
Researchers have been investigating an alternative treatment approach called adaptive therapy that focuses on maintaining disease control instead of complete tumor cell elimination. Researchers used mathematical modeling to reveal that the spatial organization of a tumor is an important factor that governs how cells compete with one another and the effectiveness of adaptive therapy.
Scientists investigating the underside of the world's largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might answer questions about what Antarctica was like before it froze, how climate change has affected it over its history, and how the ice sheet might behave as the world warms.
Are you a grade B maple syrup fan? For a lot of maple syrup connoisseurs, grade B was always the go-to syrup. It's dark, caramelly, rich, complex. But unfortunately, you can't get it anymore.
An enormous hole 22 meters in diameter has been dug near the summit of Cerro Chajnantor in Chile's Atacama Desert, at an elevation of 18,400 feet. The hole stands ready for the cement foundation on which the Fred Young Submillimeter Telescope (FYST, pronounced "feest") will one day rest. The foundation, which was designed in Chile, began construction in the fall of 2021 and is scheduled to be...
The Westdahl Peak volcano in Alaska last erupted in 1992, and continued expansion hints at another eruption soon. Experts previously forecasted the next blast to occur by 2010, but the volcano -- located under about 1 kilometer of glacial ice -- has yet to erupt again. Using the Westdahl Peak volcano as inspiration, a new volcanic modeling study examined how glaciers affect the stability and...
In June 2019, a magnitude 4.0 earthquake occurred beneath Lake Erie just off the shoreline of Ohio, about 20 miles northeast of Cleveland.
Intrinsically disordered regions (IDRs) of proteins, when tethered to folded domains, function either as flexible tails or as linkers between domains. Most IDRs are composed of a mixture of oppositely charged residues. Recent measurements of tethered polyampholytes have shown that arginine- and lysine-rich sequences tend to behave very differently from one another.
Pervasive parasitic infections reduce herbivory rates and can therefore trigger trophic cascades that impact plant communities, according to new research. This work helps fill a recognized knowledge gap regarding the ecological consequences of parasitic infections in natural ecosystems.
A hunter in Pond Inlet, Nunavut, says it's 'very scary' finding plastic inside the bellies of a fish that Inuit rely on as a source of food. A recent study, published in the journal Nature Reviews Earth & Environment, says plastic pollution in the Arctic comes from a mix of local and international...
Ubiquitous computing has triggered an avalanche of data that is beyond human processing capabilities. AI technologies have emerged as the only viable way to turn this data into information. As more computing produces more data, more computing power is needed to power AI. Next generation AI will soon look to planetary-scale computing systems to further fuel AI’s computational requirements....
Scientists investigating the underside of the world's largest ice sheet in East Antarctica have discovered a city-size lake whose sediments might contain a history of the ice sheet since its earliest beginnings. That would answer questions about what Antarctica was like before it froze, how climate change has affected it over its history, and how the ice sheet might behave as the world warms.
A new study led by Washington University in St. Louis uses a mathematical model and a global meta-analysis to highlight the cascading consequences of common parasitic infections in wild animals on terrestrial ecosystems.
There is a fierce debate raging in the deaf community.
The United Nations warned Monday that it would cost $20 billion to clean up an oil spill in the event of the "imminent" break-up of an oil tanker abandoned off Yemen.
Imagine a computer that can think as fast as the human brain while using very little energy. That's the goal of scientists seeking to discover or develop materials that can send and process signals as easily as the brain's neurons and synapses. Identifying quantum materials with an intrinsic ability to switch between two distinct forms (or more) may hold the key to these futuristic sounding...
Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have used a new technique to better forecast the level of algal toxins that accumulate in Lake Erie every year.

Three years ago, the first ever image of a black hole stunned the world. A black pit of nothingness enclosed by a fiery ring of light. That iconic image of the black hole at the center of galaxy Messier 87 came into focus thanks to the Event Horizon Telescope, a global network of synchronized radio dishes acting as one giant telescope.
Modern energy storage devices, such as supercapacitors and batteries, have highly temperature-dependent performance. If a device gets too hot, it become susceptible to "thermal runaway." Thermal runaway—or uncontrolled overheating—can ultimately result in explosions or fires. Adopting a well-informed thermal management strategy is necessary for the stable and safe operation of devices. To do...
