Even though it's been over a decade, the 2008 recession and its effects still loom over the chemistry enterprise. And now with the COVID-19 pandemic shutting down labs and universities across the world, chemistry students and professionals are again facing hiring freezes, reduced pay and other career obstacles. Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, spoke with chemists about how they're navigating the current economic downturn.
Prevalence of food allergy among Medicaid-enrolled children across the U.S. was substantially lower (0.6 percent), compared to previous national estimates using parent surveys (7.6 percent) and reports of physician confirmation of food allergy (4.7 percent). The study, published in Academic Pediatrics, was the first to analyze Medicaid claims data of over 23 million children to estimate prevalence of food allergy diagnosis.
PITTSBURGH (May 13, 2020) -- Masks, gowns, and other personal protective equipment (PPE) are essential for protecting healthcare workers. However, the textiles and materials used in such items can absorb and carry viruses and bacteria, inadvertently spreading the disease the wearer sought to contain.
When the coronavirus spread amongst healthcare professionals and left PPE in short supply, finding a way to provide better protection while allowing for the safe reuse of these items became paramount.
DURHAM, N.C. -- Biomedical engineers at Duke University are developing a massive fluid dynamics simulator that can model blood flow through the full human arterial system at subcellular resolution. One of the goals of the effort is to provide doctors with guidance in their treatment plans by allowing them to simulate a patient's specific vasculature and accurately predict how decisions such as stent placement, conduit insertions and other geometric alterations to blood flow will affect surgical outcomes.
NASA's Terra satellite revealed powerful storms in Vongfong as it ramped up from a tropical storm to a typhoon. Vongfong is known locally in the Philippines as Typhoon Ambo.
NASA's Terra satellite used infrared light to analyze the strength of storms in Vongfong. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
COLUMBUS, Ohio - Job skills training for low-income youth does more than just help them get better jobs - it makes them significantly less likely than others to use some illicit drugs, even 16 years later.
These positive effects on drug use were seen in those who received job-specific skills training, but not in youth who received only basic job services, such as help with job search or a General Education Development (GED) program.
Relationships are key to influencing positive health behaviors and should not be forgotten during social distancing due to the COVID-19 pandemic. Strong relationships can help adults stay active in older age, according to a new study from public health researchers at the University of Hawai'i at Mānoa, in collaboration with international partners.
As our smartphones, laptops, and computers get smaller and faster, so do the transistors inside them that control the flow of electricity and store information. But traditional transistors can only shrink so much. Now, researchers at Stevens Institute of Technology have developed a new atomically thin magnetic semiconductor that will allow the development of new transistors that work in a completely different way; they not only can harness an electron's charge but also the power of its spin, providing an alternative path to creating ever smaller and faster electronics.
TALLAHASSEE, Fla. -- You've probably seen the satellite images that show a hurricane developing: thick white clouds clumping together, arms spinning around a central eye as it heads for the coast.
After decades of research, meteorologists still have questions about how hurricanes develop. Now, Florida State University researchers have found that even the smallest changes in atmospheric conditions could trigger a hurricane, information that will help scientists understand the processes that lead to these devastating storms.
Researchers at the University of Illinois at Urbana-Champaign in collaboration with a Purdue team have discovered that certain crystals are more flexible and stretchable compared to current materials used for electronic applications. These new materials
could therefore be used for making sensors and in robotics.
The study “Super‐ and Ferro‐elastic Organic Semiconductors for Ultraflexible Single Crystal Electronics” was published in Angewandte Chemie, the journal of the German Chemical Society.
Every summer (November-April), the Magellan Strait in the southwestern part of Chile becomes a popular feeding area for migrating humpback whales (Megaptera novaeangliae). The narrow strait is also a heavily used shipping route. A new study by scientists at the Smithsonian Tropical Research Institute (STRI) and collaborating institutions tracked and modelled the movement of individual whales in order to evaluate the potential of vessel collisions and provide policy recommendations for the protection of whale species.
Researchers with the ECOG-ACRIN Cancer Research Group will present a wide range of research findings at the annual meeting of the American Society of Clinical Oncology (ASCO), occurring virtually May 29-31. The presentations include late-breaking data in two plenary sessions and several oral abstract presentations. National Cancer Institute, part of the National Institutes of Health, funded these studies.

Photocatalytic water splitting is one of the most promising ways to convert solar energy into the chemical one. Generally, the activity of a photocatalytic system composed of photocatalysts and cocatalysts is integrally determined by the efficiencies of basic processes such as light absorption, charge separation and surface catalysis. Conventionally, the nanoparticles of cocatalysts have been loaded on the surface of nanosized/microsized semiconductors.
Nuclear bomb tests during the Cold War may have changed rainfall patterns thousands of miles from the detonation sites, new research has revealed.
Scientists at the University of Reading have researched how the electric charge released by radiation from the test detonations, carried out predominantly by the US and Soviet Union in the 1950s and 1960s, affected rainclouds at the time.
DALLAS, May 13, 2020 -- Drinking one or more sugary beverages a day was associated with a nearly 20% greater likelihood of women having a cardiovascular disease compared to women who rarely or never drank sugary beverages, according to new research published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.
