Tropical Storm Marie has formed in the Eastern Pacific Ocean and NASA satellite data helped confirm the strengthening of the storm. In addition, using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Marie's rainfall rates the provided more clues about intensification.
Tropical Depression 18E formed on Sept. 29 by 5 p.m. EDT well southwest of the southwestern coast of Mexico. Twelve hours later the depression strengthened into a tropical storm and renamed Marie.
Marie's Status on Sept. 30
A cooler full of fish might not be the only thing anglers bring back from a trip to the lake. Unknowingly, they may also be transporting small aquatic "hitchhikers" that attach themselves to boats, motors -- and even fishing gear -- when moving between bodies of water.
BUFFALO, N.Y. -- If human societies don't sharply curb emissions of greenhouse gases, Greenland's rate of ice loss this century is likely to greatly outpace that of any century over the past 12,000 years, a new study concludes.
What The Study Did: The outcomes associated with deferred compared with expedited aortic valve replacement in patients with severe aortic stenosis during the COVID-19 pandemic are evaluated in this observational study.
Authors: Thomas Pilgrim, M.D. M.Sc., of the University of Bern in Switzerland, is the corresponding author.

Immune cells in the brain that act as scavengers to remove dying cells also play a potentially pivotal role in the regulation of behavior in both mice and humans, a research team from Mount Sinai has found. The newly identified function of the scavenger cells, known as microglia, to protect the brain from abnormal activation in health and disease has implications for treating behavioral abnormalities associated with neurodegenerative and inflammatory diseases in humans. The study was published September 30, 2020 in Nature.
An Innovative Pattern: Scientists Rewrite Rules for 2D Electronics

The phenomenon of using DNA from old fossils preserved in amber already inspired Hollywood - in the film Jurassic Park, scientists reproduce the DNA of dinosaurs extracted from a fossil mosquito embedded in a piece of amber and thereby resurrect them. In reality, however, the undertaking is much more difficult: all previous studies in which researchers took DNA samples from insects enclosed in tree resin were the results of modern environmental contamination and, in addition, were unreproducible, subsequently useless under the scientific method.
Life on Earth is all about strategies for survival, with every organism developing behaviors and bodies that maximize chances of staying alive and reproducing while minimizing the likelihood of being injured or eaten.
A study of more than a half-million people in India who were exposed to the novel coronavirus SARS-CoV-2, or COVID-19, suggests that the virus' continued spread is driven by only a small percentage of those who become infected.
Furthermore, children and young adults were found to be potentially much more important to transmitting the virus -- especially within households -- than previous studies have identified, according to a paper by researchers from the United States and India published Sept. 30 in the journal Science.
In two states in India, Tamil Nadu and Andhra Pradesh, COVID-19 cases and deaths have been more heavily concentrated in younger cohorts than is seen in high-income countries, among other trends. These results, from a study based on surveillance and contact tracing data, offer a window into the pandemic's trajectory in a low- and middle-income country, where most COVID-19 cases have occurred, and from which insights to guide control measures are urgently needed.
A new study led by researchers from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) warns that the negative effects of rapid ocean warming on planktonic communities will be exacerbated by ocean acidification.
PHILADELPHIA -- (Sept. 30, 2020) -- Researchers at The Wistar Institute unraveled a mechanism employed by chronic lymphocytic leukemia (CLL) cells for their survival. According to the study, published online in Cellular & Molecular Immunology, malignant B cells turn down expression of the STING protein to allow for increased expression of B cell receptor on their surface.
Teens who have a larger number of friends may be less likely to suffer from depression later in life, especially women, a new MSU research study has found.
Scientists at the Walter Reed Army Institute for Research and Army Research Laboratory have developed a computer-based training to reduce anger, reactive aggression and hostile attribution bias--the tendency to attribute hostile intent to the actions of others--in ambiguous social conflict situations.
SARS-CoV-2, the virus responsible for COVID-19, has wreaked havoc on health care systems, economies and everyday lives worldwide. Scientists are fighting back with multiple strategies, including vaccines, repurposed drugs developed for other diseases and brand-new therapies. Now, researchers reporting in ACS Central Science have identified small molecules that target a structure within the RNA genome of SARS-CoV-2, interfering with viral gene expression and targeting the RNA for destruction.
