(Press-News.org) Common yeast are able to adapt and thrive in response to a long-term rise in temperature by changing the shape, location and function of some of their proteins. The surprising findings demonstrate the unappreciated plasticity in the molecular and conformational level of proteins and bring the power of molecular biology to the organismal response to climate change. Results from the Zhou lab at the Buck Institute in collaboration with the Si lab from the Stowers Institute are published in Molecular Cell.
Temperature is an unstable parameter in the wild, affecting almost all aspects of life by modifying protein stability and the speed of metabolism. Buck Institute Fellow Chuankai END

The weather forecast for Venus
Little is known about the weather at night on Venus as the absence of sunlight makes imaging difficult. Now, researchers have devised a way to use infrared sensors on board the Venus orbiter Akatsuki to reveal the first details of the nighttime weather of our nearest neighbor. Their analytical methods could be used to study other planets including Mars and gas giants as well. Furthermore, the study of Venusian weather granted by their methods could allow researchers to learn more about the mechanisms underpinning Earth's weather systems. Earth and Venus ...
Genome editing meets marsupials
Researchers at the RIKEN Center for Biosystems Dynamics Research (BDR) have succeeded in creating the first genetically engineered marsupial. This study, published in the scientific journal Current Biology, will contribute to deciphering the genetic background of unique characteristics observed only in marsupials. Genetically modified animals, particularly mice and rats, are extremely important tools for researching biological processes. For example, researchers often silence genes to find out what their normal functions are. Since marsupials have unique characteristics, studying them requires developing ...
Chromosomes separation under focus
During cell division, chromosomes are duplicated and separated so that one copy of each chromosome is inherited by each of the two emerging daughter cells. Correct distribution of chromosomes requires high accuracy and defects in this process can cause aberrant distribution of chromosomes and facilitate cancer development. By analyzing the structure of the protein responsible for chromosome separation, an international team, led by scientists from the University of Geneva (UNIGE), has shed light on the mechanisms controlling this essential player in cell division. This work is published in the journal ...
"Magic-angle" trilayer graphene may be a rare, magnet-proof superconductor
MIT physicists have observed signs of a rare type of superconductivity in a material called magic-angle twisted trilayer graphene. In a study appearing in Nature, the researchers report that the material exhibits superconductivity at surprisingly high magnetic fields of up to 10 Tesla, which is three times higher than what the material is predicted to endure if it were a conventional superconductor. The results strongly imply that magic-angle trilayer graphene, which was initially discovered by the same group, is a very rare type of superconductor, known as a "spin-triplet," that is impervious to high ...
Association between COVID-19 exposure, self-reported compliance with public health guidelines among essential employees at an institution of higher education
What The Study Did: This study at an institution of higher education in Colorado evaluated the association between self-reported protective behaviors and how common SARS-CoV-2 infection was among essential in-person employees during the first six months of the COVID-19 pandemic in the United States. Authors: Tracy L. Nelson, M.P.H., Ph.D., of Colorado State University in Fort Collins, is the corresponding author.

Gender-affirming hair removal, mental health outcomes
What The Study Did: In this analysis of the 2015 U.S. Transgender Survey, gender-affirming hair removal procedures were associated with lower odds of past-month severe psychological distress, past-year smoking and past-year suicidal ideation. Authors: Michelle S. Lee, B.A., of Harvard Medical School in Boston, is the corresponding author.

Preventing approximal caries in primary teeth with topical fluorides
Alexandria, Va., USA - Parach Sirivichayakul, Mahidol University, Bangkok, Thailand, presented the poster "Preventing Approximal Caries in Primary Teeth With Topical Fluorides" at the virtual 99th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 50th Annual Meeting of the American Association for Dental Research (AADR) and the 45th Annual Meeting of the Canadian Association for Dental Research (CADR), on July 21-24, 2021. There is limited evidence regarding the use of silver diamine fluoride (SDF) for caries prevention in primary teeth. This randomized clinical trial evaluated the effectiveness of 38% SDF, 5% sodium fluoride (NaF) varnish and ...
Researchers discover a 'layer hall effect' in a 2D topological Axion antiferromagnet
Chestnut Hill, Mass. (7/21/2021) - Researchers have discovered a "layer" Hall effect in a solid state chip constructed of antiferromagnetic manganese bismuth telluride, a finding that signals a much sought-after topological Axion insulating state, the team reports in the current edition of the journal Nature. Researchers have been trying to find evidence of a topological Axion insulating (TAI) state and developed some candidate materials based on theoretical calculations. The layered Hall effect represents the first clear experimental evidence of the state, a feature bound by the laws of quantum physics, according to Boston College Assistant Professor ...
City-funded housing repairs in low-income neighborhoods associated with drop in crime
PHILADELPHIA--Investing in structural home repairs in historically segregated, low-income, Black and Latino neighborhoods has been associated with reduced crime rates. In Philadelphia, when a home received repairs through a city-funded program, total crime dropped by 21.9% on that block, and as the number of repaired houses on a block increased, instances of crime fell even further, according to research from the Perelman School of Medicine at the University of Pennsylvania published today in JAMA Network Open. In an effort to address an old housing stock and high levels of historical disinvestment in Philadelphia, the city implemented the Basic Systems Repair ...
Glass sponges have properties for the design of ships, planes and skyscrapers
Rome (Italy), July 21st, 2021 - The remarkable structural properties of the basket sponge (E. aspergillum) might seem fathoms removed from human-engineered structures. However, insights into how the organism's latticework of holes and ridges influences the hydrodynamics of seawater in its vicinity could lead to advanced designs for buildings, bridges, marine vehicles and aircraft, and anything that must respond safely to forces imposed by the flow of air or water. While past research has investigated the structure of the sponge, there have been few studies of the hydrodynamic fields ...
