Philadelphia, May 18, 2020 - Genomic selection has become a critical tool for the dairy industry around the world since genomic evaluations were first implemented in the United States and Canada in 2009.
Local variations in climate are not likely to dominate the first wave of the COVID-19 pandemic, according to a Princeton University study published May 18 in the journal Science.
The researchers found that the vast number of people still vulnerable to the strain of coronavirus causing the pandemic -- SARS-CoV-2 -- and the speed at which the pathogen spreads means that climate conditions are only likely to make a dent in the current rate of infection.
When it comes to wine, the chemistry must be right to get the best taste and sensation.
To help winemakers with that chemistry, a team of researchers at Washington State University has made it easier to test the chemical makeup of their red wine to get the vino they're looking for.
In a paper released last month in the journal Molecules, the scientists presented a new model that allows winemakers to get measurements in their wine that previously required difficult, tedious, or expensive testing.
New research from CSHL scientists suggests that cigarette smoke spurs the lungs to make more ACE2 (angiotensin-converting enzyme 2), the protein that the coronavirus responsible for COVID-19 grabs and uses to enter human cells. The findings, reported May 16, 2020 in the journal Developmental Cell, may explain why smokers appear to be particularly vulnerable to severe infections. The analysis also indicates that the change is reversible, suggesting that quitting smoking might reduce the risk of a severe coronavirus infection.
Far below the Earth's surface, about 1,800 miles deep, lies a roiling magmatic region sandwiched between the solid silicate-based mantle and molten iron-rich core: The core-mantle boundary. It's a remnant of olden times, the primordial days about 4.5 billion years ago when the entire planet was molten, an endless sea of magma. Although the region's extreme pressures and temperatures make it difficult to study, it contains clues about the mysterious origin story of the world as we know it.
Sometimes scientists begin research and find exactly what they expected. Other times they discover something unexpected. Such was the case for a group of scientists studying plant stress responses who stumbled upon a new mutation.
"The discovery of this mutation was actually a surprise," said first author Matt Neubauer. "And by trying to better understand this new mutation, and what effect it had on plant stress responses, we uncovered new information about how different plant stress regulators function."

TALLAHASSEE, Fla. -- A Florida State University researcher has used new detection methods to identify 85 previously unknown submarine landslides that occurred in the Gulf of Mexico between 2008 and 2015, leading to questions about the stability of oil rigs and other structures, such as pipelines built in the region.
Assistant Professor Wenyuan Fan in the Department of Earth, Ocean and Atmospheric Science has published a new paper in the journal Geophysical Research Letters that identifies these landslides and the risks they pose to coastal communities.
It is not uncommon to find aluminum in municipal water systems. It's part of a treatment chemical used in some water treatment processes. Recently, however, it has been discovered in lead scale, deposits that form on lead water pipes.

Humans have been wondering whether we alone in the universe since antiquity.
We know from the geological record that life started relatively quickly, as soon our planet's environment was stable enough to support it. We also know that the first multicellular organism, which eventually produced today's technological civilization, took far longer to evolve, approximately 4 billion years.
In the latest CUNY SPH COVID-19 tracking survey, New Yorkers gave convincing evidence that the city is not yet testing enough people and set high expectations for the safety measures they feel are necessary for them to return to work outside their homes. They are also uncertain about reopening public schools, colleges or universities in the fall. These are the major findings of the ninth city and statewide tracking survey from the CUNY Graduate School of Public Health & Health Policy (CUNY SPH), conducted May 15-17.
LA JOLLA--(May 18, 2020) Many cancer medications fail to effectively target the most commonly mutated cancer genes in humans, called RAS. Now, Salk Professor Geoffrey Wahl and a team of scientists have uncovered details into how normal RAS interacts with mutated RAS and other proteins in living cells for the first time. The findings, published in The Proceedings of the National Academy of Sciences on May 18, 2020, could aid in the development of better RAS-targeted cancer therapeutics.
New data suggests that asthma is associated with longer time on ventilators for hospitalized younger patients with COVID-19. Patients with COVID-19 between the ages of 20 and 59 years old who also had asthma needed a ventilator to assist with breathing for five days more on average than non-asthmatic patients with COVID-19, according to researchers at Rush University Medical Center, who published their findings today in The Journal of Allergy and Clinical Immunology: In Practice.
Researchers from Sechenov University (Russia) and University of Pittsburgh (USA) discovered that the resistance of innate immune cells, macrophages, to ferroptosis - a type of programmed cell death - depends on the type of their activation. It turned out that cells helping tissues to recover from inflammation were more vulnerable. The researchers identified the mechanisms underlying the cells' resistance and explained how this research would help regulate inflammation in a paper published in Nature Chemical Biology.
