A new study by investigators from Mass General Brigham found that one in five individuals taking Nirmatrelvir-ritonavir therapy, commonly known as Paxlovid, to treat severe symptoms of COVID-19, experienced a positive test result and shedding of live and potentially contagious virus following an initial recovery and negative test—a phenomenon known as virologic rebound. By contrast, people not taking Paxlovid only experienced rebound about 2 percent of the time. Results are published in Annals of Internal Medicine. “We conducted this study to address lingering questions about Paxlovid and virologic rebound in COVID-19 treatment,” said corresponding ...

Ammonia, a main component of many fertilizers, could play a key role in a carbon-free fuel system as a convenient way to transport and store clean hydrogen. The chemical, made of hydrogen and nitrogen (NH3), can also itself be burned as a zero-carbon fuel. However, new research led by Princeton University illustrates that even though it may not be a source of carbon pollution, ammonia’s widespread use in the energy sector could pose a grave risk to the nitrogen cycle and climate without proper engineering precautions. Publishing their findings in PNAS, the interdisciplinary team of 12 researchers found that a well-engineered ammonia economy could help the world achieve ...

November 13, 2023-- There is no longer any question of how to prevent high-intensity, often catastrophic, wildfires that have become increasingly frequent across the Western U.S., according to a new study by researchers at Columbia University Mailman School of Public Health and Stanford University. The analysis reveals that low-intensity burning, such as controlled or prescribed fires, managed wildfires, and tribal cultural burning, can dramatically reduce the risk of devastating fires for years at a time. The findings are some of the first to rigorously quantify the value of low-intensity fire and be released while Congress is reassessing ...

Banding together to sell fishing rights could generate economic benefits for African countries, which receive far less from access to their fisheries on the global market than other countries do from theirs. By joining forces, UC Santa Barbara researchers say in a paper published in the journal Nature Communications, African fisheries would not just secure more competitive access fees, they could also protect their seas’ biodiversity. “If African countries created a ‘fish cartel’ to sell fishing rights to foreign vessels, they could increase their fish biomass by 16% and make 23% more in profits,” ...

In patients with severe artery blockage in the lower leg, an artery-supporting device called a resorbable scaffold is superior to angioplasty, which has been the standard treatment, according to the results of a large international clinical trial co-led by researchers at Weill Cornell Medicine and NewYork-Presbyterian. Angioplasty involves the widening of a narrowed artery with a small, balloon-like mechanism. A resorbable scaffold is a stent-like structure that props the artery open but is biodegradable and dissolves within a few years, avoiding some of the potential complications of a permanent ...

A compound—one of 27 million screened in a library of potential new drugs—reversed four types of chronic pain in animal studies, according to new research led by NYU College of Dentistry’s Pain Research Center and published in the Proceedings of the National Academy of Sciences (PNAS). The small molecule, which binds to an inner region of a calcium channel to indirectly regulate it, outperformed gabapentin without troublesome side effects, providing a promising candidate for treating pain. Calcium channels play a central role in pain signaling, in part through the release of neurotransmitters such as glutamate and GABA— “the ...

An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer’s and Parkinson’s Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone.  The team tested the device on in vitro samples from patients and showed that it is as accurate as the state of the art. Ultimately, researchers plan to test saliva and urine samples with the biosensor. The device could be modified to detect biomarkers for other conditions as well.  Researchers present their findings ...

A research team from the University of Cologne, in collaboration with colleagues from the Leibniz Institute for Food Systems Biology in Freising, has discovered a receptor for bitter taste in twelve different cartilaginous fish (sharks and rays). The receptor belongs to the so-called taste receptors type 2 (T2R), which also make humans perceive bitter and potentially toxic foods. Until now, it was assumed that such receptors only occur in bony vertebrates. The work was published under the title ‘A singular shark bitter taste receptor provides insights into the evolution of bitter taste perception’ ...

To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. A prominent 2019 study used ice cores in Antarctica to suggest that marine productivity in the North Atlantic had declined by 10% during the industrial era, with worrying implications that the trend might continue. But new research led by the University of Washington shows that marine phytoplankton — on which larger organisms throughout the marine ecosystem depend — may be more stable than believed in the North Atlantic. The team’s analysis of an ice core going ...

People with arthritis who report more negative feelings about how they are aging tend to get less physical activity and perceive themselves as less healthy, according to a new study by researchers at Hospital for Special Surgery (HSS) and Weill Cornell Medicine. However, self-perception of good health explained the effect of negative thinking – providing an opportunity for clinicians to focus on a patient’s outlook on aging as well as their overall health. “Physical activity is essential for older adults with arthritis, as it can help to reduce pain and stiffness, improve ...

Researchers at Karolinska Institutet and SciLifeLab in Sweden have combined artificial intelligence (AI) techniques used in satellite imaging and community ecology to interpret large amounts of data from tumour tissue. The method, presented in the journal Nature Communications, could contribute to more personalised treatment of cancer patients. While recent advances in tumour imaging provide a great insight into the microscopic world of tumours, the challenge is to interpret the huge amount of data generated. With hundreds of molecules being measured simultaneously in tens or hundreds of thousands of cells, it has become difficult for researchers to know what molecules and cells ...

  Media kit New research suggests that a realistic estimate of additional global forest carbon-storage potential is approximately 226 gigatonnes of carbon—enough to make a meaningful contribution to slowing climate change.   The study, published today in the journal Nature, highlights the critical importance of forest conservation, restoration and sustainable management in moving toward international climate and biodiversity targets. It involved hundreds of scientists around the world, who stress that this potential can be achieved by incentivizing community-driven efforts to promote biodiversity.   Forest ...

ST. LOUIS, MO, November 13, 2023 — An international research team led by James Umen, PhD, member, Donald Danforth Plant Science Center has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division. Chlamydomonas cells can grow very large and then divide multiple times in succession. The team found that the number of divisions a mother cell undertakes to restore its daughters to the correct starting size deviates from the mathematical optimum that was assumed to dictate ...

PARIS, NOV. 13—Representatives from the U.S. Department of Energy’s (DOE) Office of Science and the French Alternative Energies and Atomic Energy Commission (CEA) have signed a “Statement of Interest” to launch what both agencies hope will be a significant collaboration on the Electron-Ion Collider (EIC).
