Five researchers shed new light on a key argument to reduce greenhouse gases (GHG): they provided the first economic analysis of conversion factors of other GHG like methane into their CO2 equivalent in overshoot scenarios. Although the United Nations Framework Convention on Climate Change (UNFCCC) considers settling for one value of reference (known as "Common Metric") to make this conversion among the Paris Agreement, the models presented here show the economic advantage of flexibility between various factors of conversion. "A key notion in the UNFCCC is to reduce GHG emissions in the least costly way so as to ensure global benefits" highlights Katsumasa Tanaka, primary author of the Science Advances study. The research provides series of dynamic variations of ...

A study coordinated by Luís Graça, principal investigator at the Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal) and Professor at the Faculty of Medicine of the University of Lisbon (FMUL) used lymph nodes, tonsils and blood, to show how the cells that control production of antibodies are formed and act. The results published now in the scientific journal Science Immunology* unveiled key aspects about the regulation of antibody production, with significant importance for diseases where antibody production is dysregulated such as autoimmune diseases or allergies. In the last few ...

A new study of dozens of wild fish species commonly consumed in the Peruvian Amazon says that people there could suffer major nutritional shortages if ongoing losses in fish biodiversity continue. Furthermore, the increasing use of aquaculture and other substitutes may not compensate. The research has implications far beyond the Amazon, since the diversity and abundance of wild-harvested foods is declining in rivers and lakes globally, as well as on land. Some 2 billion people globally depend on non-cultivated foods; inland fisheries alone employ some 60 million people, and provide the primary source of protein for some 200 million. The study appears this week in the journal Science Advances. The ...

Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change, according to new research published in Science Advances. "Up till now, the magnitude of past fire activity, and thus the amount of smoke in the preindustrial atmosphere, has not been well characterized," said Pengfei Liu, a former graduate student and postdoctoral fellow at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and first author of the paper. "These results have importance for understanding the evolution of climate change from the 1750s until ...

Since the onset of the CRISPR genetic editing revolution, scientists have been working to leverage the technology in the development of gene drives that target pathogen-spreading mosquitoes such as Anopheles and Aedes species, which spread malaria, dengue and other life-threatening diseases. Much less genetic engineering has been devoted to Culex genus mosquitoes, which spread devastating afflictions stemming from West Nile virus--the leading cause of mosquito-borne disease in the continental United States--as well as other viruses such as the Japanese encephalitis virus (JEV) and the pathogen causing avian malaria, a threat to ...

Neurological disorders such as Parkinson's disease and epilepsy have had some treatment success with deep brain stimulation, but those require surgical device implantation. A multidisciplinary team at Washington University in St. Louis has developed a new brain stimulation technique using focused ultrasound that is able to turn specific types of neurons in the brain on and off and precisely control motor activity without surgical device implantation. The team, led by Hong Chen, assistant professor of biomedical engineering in the McKelvey School of Engineering and of radiation oncology at the School of Medicine, is the first to provide direct evidence showing noninvasive, cell-type-specific ...

Corals are in trouble. All across the globe the diverse and dynamic ecosystems are taking huge hits year after year. The Great Barrier Reef has lost half of its coral since 1995. Scientists are seeing similar declines in reefs from Hawai'i to the Florida Keys and across the Indo-Pacific region. The widespread decline is fueled in part by climate-driven heatwaves that induce coral bleaching -- the breakdown of the relationship between shallow-water coral and the symbiotic algae they rely upon for nutrients. Climate change is a clear and present danger to the persistence of coral reefs, and global reductions in carbon emissions is ...

East Hanover, NJ. May 28, 2021. A team of multiple sclerosis (MS) experts at Kessler Foundation led the first pilot randomized controlled trial of robotic-exoskeleton assisted exercise rehabilitation (REAER) effects on mobility, cognition, and brain connectivity in people with substantial MS-related disability. Their results showed that REAER is likely an effective intervention, and is a promising therapy for improving the lives of those with MS. The article, "A pilot randomized controlled trial of robotic exoskeleton-assisted exercise rehabilitation in multiple sclerosis," (doi: 10.1016/j.msard.2021.102936) was published on April 4, 2021, by Multiple Sclerosis and Related Disorders. It is available open access at https://www.msard-journal.com/article/S2211-0348(21)00203-0/fulltext. The ...

Adults with cerebral palsy are more likely to experience the debilitating pains of musculoskeletal disorders, but they receive significantly less physical therapy for those ailments, according to a recent study. The findings, published in Disability & Health, analyzed four years of Medicare service claims from community-living older adults with and without cerebral palsy who had one or more ambulatory claims for a musculoskeletal diagnosis. Fewer than one-third of general population patients utilized physical therapy. Those with cerebral palsy, despite having greater risk of secondary comorbid conditions, received even less physical therapy. "The results are staggering, but they support our hypothesis that people with cerebral palsy receive inequitable health care," says Mark ...

Climate change will make outbreaks of West Nile virus more likely in the UK within the next 20-30 years, scientists say. West Nile virus is spread by mosquitoes and has no vaccine. Most people have no symptoms, but it can cause serious neurological disease. Scientists from the UK Centre for Ecology & Hydrology (UKCEH), Biomathematics and Statistics Scotland (BioSS) and the University of Glasgow developed a new model to determine the risk of a West Nile virus outbreak in the UK. They found the risk is low for the next two to three decades, but will increase as temperatures ...

The drug diABZI -- which activates the body's innate immune response -- was highly effective in preventing severe COVID-19 in mice that were infected with SARS-CoV-2, according to scientists in the Perelman School of Medicine at the University of Pennsylvania. The findings, published this month in Science Immunology, suggest that diABZI could also treat other respiratory coronaviruses. "Few drugs have been identified as game-changers in blocking SARS-CoV-2 infection. This paper is the first to show that activating an early immune response therapeutically with a single dose is a promising strategy for controlling the virus, including the South African variant ...

As hospitals, insurance companies and policy makers seek to improve healthcare quality and reduce rising medical costs, one important metric used to assess clinicians hinges on how patients feel about their healthcare experience. Many healthcare providers and policy makers fear that increased pressure to please patients -- and ensure high satisfaction ratings as a result -- could lead to overuse of low-value care that doesn't provide any clinical benefit while unnecessarily ratcheting up medical bills. But new research from the University of Chicago and Harvard Medical School may alleviate some of those concerns. The study, published May 28 in END ...

The National Cancer Institute (NCI), part of the National Institutes of Health, funded these studies. Breast Cancer Platinum chemotherapy fails in phase III trial for triple-negative breast cancer, basal-like subtype Abstract 605: About 80% of triple-negative breast cancers (TNBC) are a subtype called 'basal-like.' ...

Your immune system is always busy fighting incoming threats. It consists of a system of cells, and when there is a shortage of cells, it affects the performance of the immune system. This is seen in e.g. cancer patients following chemotherapy. This is because chemotherapy targets all the cells in your body, including the stem cells in your bone marrow, which were meant to develop into new immune cells. This means that the immune system then lacks cells to fight new infections. There are drugs that can harvest stem cells from the bone marrow, so that they can be returned to the patients after treatment. They then develop into new immune cells, enabling the body to once again fight incoming threats. But previously, we lacked ...

COLUMBUS, Ohio - If you've watched a slasher movie, you've probably been exposed to the final girl trope - a closing scene of a white, suburban teenage girl who triumphed over a threatening monster and lived to tell the tale. But her story doesn't stop there - in some ways, a whole new life, overshadowed by trauma, has only just begun, Ohio State University graduate student Morgan Podraza posits in an article published in the journal Horror Studies. Consider actor Jamie Lee Curtis' depiction of Laurie Strode in the Halloween film released in 2018, 40 years after her friends were murdered by Michael Myers on Halloween night. ...
