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

- 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.

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...

- 21/1/4 20:34
A growing number of women forgoing reconstruction after a mastectomy say they're satisfied with their choice, even as some did not feel supported by their physician, according to a new study.
Antibiotic-resistant bacteria: Fluoride to the rescue?
- ScienceDaily
- 21/1/4 20:15
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...
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.
New tool for reconstructing ancient sea ice to study climate change
- ScienceDaily
- 21/1/4 19:19
A previously problematic molecule turns out to be a reliable proxy for reconstructing sea ice, a new study by Brown University researchers shows.

Doubt is cast on the long-held hope that the conservation protections granted pandas and other adored threatened species extended to their wildlife neighbors, calling for broader conservation efforts.
Single-cell analysis of metastatic gastric cancer finds diverse tumor cell populations associated with patient outcomes
- ScienceDaily
- 21/1/4 19:19
Researchers who profiled more than 45,000 individual cells from patients with peritoneal carcinomatosis (PC), a specific form of metastatic gastric cancer, defined the extensive cellular heterogeneity and identified two distinct subtypes correlated with patient survival.

Researchers describe, how structural defects in self-assembling nacre attract and cancel each other out, eventually leading to a perfect periodic structure.
Better together: Scientists discover applications of nanoparticles with multiple elements
- ScienceDaily
- 21/1/4 19:19
As catalysts for fuel cells, batteries and processes for carbon dioxide reduction, alloy nanoparticles that are made up of five or more elements are shown to be more stable and durable than single-element nanoparticles.

Chemists succeed in synthesis of aminoalcohols by utilizing light
- ScienceDaily
- 21/1/4 19:19
So-called vicinal aminoalcohols are high-quality organic compounds that are found in many everyday products. However, their production is difficult. In their recent study, scientists have found a solution for the production of a special variant of aminoalcohols.
Fires, flooding before settlement may have formed the Amazon's rare patches of fertility
- ScienceDaily
- 21/1/4 19:19
Phosphorous, calcium and charcoal in spotty patches of fertile soil in the Amazon rainforest suggest that natural processes such as fires and river flooding, not the ingenuity of indigenous populations, created rare sites suitable for agriculture, according to new research.
Prediabetes subtypes identified
