Reawakened geyser does not foretell Yellowstone volcanic eruptions
- ScienceDaily
- 21/1/4 23:01
Geyser eruptions, like volcanic eruptions, are a mystery, so the reactivation of Steamboat Geyser in Yellowstone in 2018 provided an opportunity to explore why geysers turn off and on, and what determines their periodicity. Researchers found little evidence of magma moving below the geyser, meaning no sign of imminent hydrothermal eruptions, but did discover a relationship between the height of...
Study resolves long-running controversy over critical step in gene silencing
- ScienceDaily
- 21/1/4 23:01
Researchers have identified a molecular 'address' that explains how the cancer-related protein PRC2 binds to RNA to silence genes. The study resolves a longstanding debate about the contradictory behavior between PRC2 and RNA. The findings could have important implications for development of drugs to treat cancer and other diseases.
Scientists develop new approach to understanding massive volcanic eruptions

Scientists develop new approach to understanding massive volcanic eruptions
A geosciences team led by the University of South Florida (USF) has developed a new way to reconstruct the sizes of volcanic eruptions that occurred thousands of years ago, creating a first-of-its kind tool that can aid scientists in understanding past explosive eruptions that shaped the earth and improve the way of estimating hazards of future eruptions.
Uncovering how plants see blue light
Plants can perceive and react to light across a wide spectrum. New research from Prof. Nitzan Shabek's laboratory in the Department of Plant Biology, College of Biological Sciences shows how plants can respond to blue light in particular.
Study resolves long-running controversy over critical step in gene silencing
A long-running debate over how an important gene-silencing protein identifies its targets has been resolved by researchers at Massachusetts General Hospital (MGH). Their findings, reported in Nature Structural and Molecular Biology, also explain certain mysteries about the behavior of this protein, known as Polycomb repressive complex 2 (PRC2).
Gas pressure depletion and seismicity
Europe's largest gas field, the Groningen field in the Netherlands, is widely known for induced subsidence and seismicity caused by gas pressure depletion and associated compaction of the sandstone reservoir. Whether compaction is elastic or partly inelastic, as implied by recent experiments, is key to forecasting system behavior and seismic hazard.
Traditional stereotypes about masculinity may help explain support for Trump
American politicians have long been expected to uphold a certain veneer: powerful, influential and never vulnerable. New Penn State research has found that these idealized forms of masculinity may also help explain support for Donald Trump in the 2016 presidential election and in the days leading up to the 2020 election.
Reawakened geyser does not foretell Yellowstone volcanic eruptions, study shows
When Yellowstone National Park's Steamboat Geyser—which shoots water higher than any active geyser in the world—reawakened in 2018 after three and a half years of dormancy, some speculated that it was a harbinger of possible explosive volcanic eruptions within the surrounding geyser basin. These so-called hydrothermal explosions can hurl mud, sand and rocks into the air and release hot steam,...
New study on circadian clock shows 'junk DNA' plays a key role in regulating rhythms
- ScienceDaily
- 21/1/4 20:59
Researchers have been trying to figure out what regulates molecular circadian clocks, in search of new insights into diseases like Alzheimer's, cancer and diabetes. Until now, that research has focused on what is known as clock genes. But new research reveals the discovery of a new cog in the circadian clock - a genome-wide regulatory layer made up of small chains of non-coding nucleotides known...

Plants can perceive and react to light across a wide spectrum. New research shows how plants can respond to blue light in particular by revealing the structure of cryptochrome-2, the molecule that reacts to blue light.
First glimpse of polarons forming in a promising next-gen energy material
Polarons are fleeting distortions in a material's atomic lattice that form around a moving electron in a few trillionths of a second, then quickly disappear. As ephemeral as they are, they affect a material's behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab.
Fluoride to the rescue? Addressing the challenge of antibiotic-resistant bacteria
Scientists have long been aware of the dangerous overuse of antibiotics and the increasing number of antibiotic-resistant microbes that have resulted. While over-prescription of antibiotics for medicinal use has unsettling implications for human health, so too does the increasing presence of antibiotics in the natural environment. The latter may stem from the improper disposal of medicines, but...

Researchers found that focusing on diversion -- instead of detention -- yields positive results for youth with behavioral health issues.
More women embracing 'going flat' after mastectomy

New clues on why pregnancy may increase risk of organ transplant rejection
- ScienceDaily
- 21/1/4 19:19
A research study has found that in pregnancy, while the T cell response to a fetus becomes tolerant to allow for successful pregnancy, the part of the immune system that produces antibodies (known as the humoral response) becomes sensitized, creating memory B cells that can later contribute to the rejection of a transplanted organ.
