The American Chemical Society (ACS) is a nonprofit organization chartered by the U.S. Congress. ACS' mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and all its people. The Society is a global leader in promoting excellence in science education and providing access to chemistry-related information and research through its multiple research solutions, peer-reviewed journals, scientific conferences, eBooks and weekly news periodical Chemical & Engineering News. ACS journals are among the most cited, most trusted and most read within the scientific literature; however, ACS itself does not conduct chemical research. As a specialist in scientific information solutions (including SciFinder® and STN®), its CAS division powers global research, discovery and innovation. ACS' main offices are in Washington, D.C., and Columbus, Ohio.

What are forever chemicals, and do they last forever? (video)
2021-04-05
(Press-News.org) WASHINGTON, April 5, 2021 -- Forever chemicals are known for being water-, heat- and oil-resistant, which makes them useful in everything from rain jackets to firefighting foams. But the chemistry that makes them so useful also makes them stick around in the environment and in us -- and that could be a bad thing: https://youtu.be/tqKEG5LxPiY.

Deep dive into key COVID-19 protein is a step toward new drugs, vaccines
2021-04-05
CORVALLIS, Ore. - Researchers in the Oregon State University College of Science have taken a key step toward new drugs and vaccines for combating COVID-19 with a deep dive into one protein's interactions with SARS-CoV-2 genetic material.
The virus' nucleocapsid protein, or N protein, is a prime target for disease-fighting interventions because of the critical jobs it performs for the novel coronavirus' infection cycle and because it mutates at a comparatively slow pace. Drugs and vaccines built around the work of the N protein carry the potential to be highly effective and for longer periods of time - i.e., less susceptible to resistance.
Among the SARS-CoV-2 proteins, ...
New 'quantum' approach helps solve an old problem in materials science
2021-04-05
Ishikawa, Japan - One of the most important classes of problems that all scientists and mathematicians aspire to solve, due to their relevance in both science and real life, are optimization problems. From esoteric computer science puzzles to the more realistic problems of vehicle routing, investment portfolio design, and digital marketing--at the heart of it all lies an optimization problem that needs to be solved.
An appealing technique often used in solving such problems is the technique of "quantum annealing", a framework that tackles optimization problems by using "quantum tunneling"--a quantum physical phenomenon--to pick out an optimum solution out of several candidate solutions. ...
POLST and other advance medical planning should not be a one-time conversation
2021-04-05
INDIANAPOLIS -- The high incidence of COVID-19 and resulting sudden changes in the health of many long-stay nursing home residents across the country have amplified the importance of advance care planning and the need for periodic review of the process, especially as widespread vaccination changes the calculus of the disease.
Two new studies from Indiana University and Regenstrief Institute focus on POLST, a medical order form widely used in nursing homes that documents what life-sustaining treatments a person prefers to receive or not receive, such as hospitalization or comfort-focused care. The studies, published online ...
Adult nocturnal fishflies found to visit flowers for food
2021-04-05
Researchers from Kumamoto University (Japan) have found that adult nocturnal fishflies (Neochauliodes amamioshimanus), which are typically aquatic insects, feed on pollen at night. They also present circumstantial evidence suggesting that this species not only forages in flowers, but is also a supplementary pollinator. Their work sheds light on the terrestrial life of adult fishflies, which has been a mystery until now.
Megaloptera is a small taxon (about 400 species worldwide) consisting of the families Sialidae (alderflies) and Corydalidae (dobsonflies and fishflies), and is considered to be one of the oldest groups of insects that undergo complete metamorphosis. The biology of the fishfly's aquatic larvae, which were sometimes used as folk remedies in Japan, is relatively well understood. ...
Doping by athletes could become tougher to hide with new detection method
2021-04-05
WASHINGTON, April 5, 2021 -- As the world awaits the upcoming Olympic games, a new method for detecting doping compounds in urine samples could level the playing field for those trying to keep athletics clean. Today, scientists report an approach using ion mobility-mass spectrometry to help regulatory agencies detect existing dopants and future "designer" compounds.
The researchers will present their results today at the spring meeting of the American Chemical Society (ACS). ACS Spring 2021 is being held online April 5-30. Live sessions will be hosted April 5-16, and on-demand and networking content will continue through April 30. The meeting features nearly 9,000 presentations ...
Making cleaner, greener plastics from waste fish parts
2021-04-05
WASHINGTON, April 5, 2021 -- Polyurethanes, a type of plastic, are nearly everywhere -- in shoes, clothes, refrigerators and construction materials. But these highly versatile materials can have a major downside. Derived from crude oil, toxic to synthesize, and slow to break down, conventional polyurethanes are not environmentally friendly. Today, researchers discuss devising what they say should be a safer, biodegradable alternative derived from fish waste -- heads, bones, skin and guts -- that would otherwise likely be discarded.

Paleopharmaceuticals from Baltic amber might fight drug-resistant infections
2021-04-05
WASHINGTON, April 5, 2021 -- For centuries, people in Baltic nations have used ancient amber for medicinal purposes. Even today, infants are given amber necklaces that they chew to relieve teething pain, and people put pulverized amber in elixirs and ointments for its purported anti-inflammatory and anti-infective properties. Now, scientists have pinpointed compounds that help explain Baltic amber's therapeutic effects and that could lead to new medicines to combat antibiotic-resistant infections.

Certain high blood pressure medications may alter heart risk in people with HIV
2021-04-05
DALLAS, April 5, 2021 -- When people with human immunodeficiency virus (HIV) develop high blood pressure, the type of medication chosen for their initial treatment may influence their risk of heart disease, stroke and heart failure, according to new research published today in Hypertension, an American Heart Association journal.
With current anti-retroviral medications, people with HIV are able to live longer. However, people with HIV receiving anti-retroviral therapy (ART) are more likely to develop high blood pressure (hypertension) and hypertension-related heart problems than people who do not have the virus. The current study is the first to examine how the choice of blood pressure medications influences the long-term risk of heart disease, stroke and ...
Rise of oxygen on Earth: Initial estimates off by 100 million years
2021-04-05
New research shows the permanent rise of oxygen in our atmosphere, which set the stage for life as we know it, happened 100 million years later than previously thought.
A significant rise in oxygen occurred about 2.43 billion years ago, marking the start of the Great Oxidation Episode -- a pivotal moment in Earth's history.
An international research team including a UC Riverside scientist analyzed rocks from South Africa formed during this event. Findings, published this week in the journal Nature, include the discovery that oxygen fluctuated dramatically after its early appearance until it became a permanent constituent of the atmosphere much later.
These ...
NIH scientists develop breath test for methylmalonic acidemia
2021-04-05
Researchers at the National Institutes of Health have developed a breath test that measures how well patients with methylmalonic acidemia (MMA) respond to receiving liver or combined liver and kidney transplantation. Researchers also used the test to assess the severity of the disease in people and help determine if they would benefit from surgical or experimental genomic therapies that target the liver. The study results were published in Genetics in Medicine. Scientists at the National Human Genome Research Institute (NHGRI) led the project team, with collaborators from the National ...
