Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of applications, from discarded plastics. The process has the potential to create more sustainable and economically favorable lifecycles for plastics.
There is consistent, strong evidence that the SARS-CoV-2 virus, which causes COVID-19, is predominantly transmitted through the air, according to a new assessment published today in the medical journal Lancet. Therefore, public health measures that fail to treat the virus as predominantly airborne leave people unprotected and allow the virus to spread, according to six experts from the UK, USA and Canada, including Jose-Luis Jimenez, chemist at the Cooperative Institute for Research in Environmental Sciences (CIRES) and University of Colorado Boulder.
From cancer treatment to sunlight, radiation and toxins can severely damage DNA in both harmful and healthy cells. While the body has evolved to efficiently treat and restore damaged cells, the mechanisms that allow this natural repair remain misunderstood.
Infection with parasitic intestinal worms (helminths) can apparently cause sexually transmitted viral in-fections to be much more severe elsewhere in the body. This is shown by a study led by the Universities of Cape Town and Bonn. According to the study, helminth-infected mice developed significantly more severe symptoms after infection with a genital herpes viruses (Herpes Simplex Virus). The researchers suspect that these results can also be transferred to humans. The results have now appeared in the journal Cell Host & Microbe.
One dose of SARS-CoV-2 mRNA vaccine may induce immunity in recovered patients, suggests new analysis
A new analysis of antibody and B cell responses in 44 people who received either the Pfizer or Moderna mRNA SARS-CoV-2 mRNA vaccines shows that only one dose may be needed for previously infected patients who have since recovered. The study also supported that two doses is optimal to induce strong antibody and B cell responses in patients who are immunologically naïve for SARS-CoV-2, and antibodies induced by the vaccination could protect against the more infectious and deadly South African variant.
A new study from North Carolina State University found that, on average, voters and local leaders showed greater concern about plastic and other garbage in the ocean after watching kids' presentations.
The findings, published in the journal Frontiers in Political Science, built on previous research that found educating kids about climate change was linked to an increase in concern in parents. The new findings indicate kids can have a broader impact outside of their families.
A pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas - called an accretion disk - that surrounds each one.
New research from the Florida State University College of Medicine has found that the personality trait neuroticism is consistently associated with a higher risk of developing the brain disorder Parkinson's disease.
The research by Professor of Geriatrics Antonio Terracciano and team, published in Movement Disorders, found that adults in the study who scored in the top quartile of neuroticism had more than 80% greater risk of Parkinson's, compared to those who scored lower on neuroticism.
In a newly released study, researchers found that remote and virtual care models can negatively impact small physician offices. Three researchers from University of Colorado Denver conducted the study, which was published in the National Library of Medicine.
Neurological disorders are the number one cause of disability in the world, leading to seven million deaths each year. Yet few treatments exist for these diseases, which progressively diminish a person's ability to move and think.
Two MIT professors have proposed a new approach to estimating the risks of exposure to Covid-19 under different indoor settings. The guideline they developed suggests a limit for exposure time, based on the number of people, the size of the space, the kinds of activity, whether masks are worn, and the ventilation and filtration rates. Their model offers a detailed, physics-based guideline for policymakers, businesses, schools, and individuals trying to gauge their own risks.
URBANA, Ill. - Australian pineapple, Danish trout, and Midwestern U.S. corn farmers are not often lumped together under the same agricultural umbrella. But they and many others who raise crops and animals face a common problem: excess nitrogen in drainage water. Whether it flows out to the Great Barrier Reef or the Gulf of Mexico, the nutrient contributes to harmful algal blooms that starve fish and other organisms of oxygen.
LA JOLLA, CA--Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses--and now, scientists at Scripps Research have illuminated how these antibodies can disable the viruses so effectively. The insights may be helpful for developing effective therapies.
Ebolavirus is a family of often-deadly viruses that includes Ebola virus and many lesser-known viruses such as Bundibugyo virus, Sudan virus and Reston virus.
A team of scientists used a telescope on the International Space Station to measure the size of PSR J0740+6620 (J0740, for short), the most massive known neutron star. NASA’s Neutron star Interior Composition Explorer (NICER) has captured unprecedented detail from this stellar remnant to learn more about matter in its core, which is on the threshold of collapsing into a black hole.
Researchers from Skoltech and a major European bank have developed a neural network that outperforms existing state-of-the art solutions in using transactional banking data for customer credit scoring. The research was published in the proceedings of the 2020 IEEE International Conference on Data Mining (ICDM).
