University of Arkansas researchers developed a tree-ring chronology from the Amazon River basin that established a link between climate patterns in the Amazon and the Americas.
The key to promoting the hydrogen economy represented by hydrogen vehicles is to produce hydrogen for electricity generation at an affordable price. Hydrogen production methods include capturing by-product hydrogen, reforming fossil fuel, and electrolyzing water. Water electrolysis in particular is an eco-friendly method of producing hydrogen, in which the use of a catalyst is the most important...
University of Adelaide scientists have shown how droughts are threatening the health of wetlands globally. Published in the journal Earth-Science Reviews, the scientists highlight the many physical and chemical changes occurring during droughts that lead to severe, and sometimes irreversible, drying of wetland soils.
Female surgeons at a large academic medical center perform less complex surgical procedures than their male counterparts, according to a new study. This study is one of the first to measure the problem of underemployment among female surgeons in the United States, which can affect compensation, career advancement and job satisfaction.
The study, published in PLOS ONE, looked at the number of deaths in each of the 7,251 local authority areas of Italy during the first four months of the year and compared these figures with predictions based on data from 2016-2019. It found that Lombardy had the most excess deaths of any region in Italy.
Scientists from the University of Plymouth showed increased temperature and acidification of our oceans over the next century could have a range of effects on an economically important marine species
Cambridge research shows a 'pre-bunk' game can reduce susceptibility to fake news for up to three months after just one play. Latest findings come as new Go Viral! game is launched in partnership with the UK Government to fight the spread of COVID-19 false information. * The games let users play the role of a fake news producer so they can understand how misinformation is circulated online.
In a recent study, researchers from Fujian Agriculture and Forestry University (FAFU) and the Xishuangbanna Tropical Botanical Garden (XTBG) provided insights into fig-wasp coevolution through comparative analyses of two Ficus genomes - one with aerial roots and one without, one monecious and one dioecious, as well as the genome of a coevolving wasp pollinator. They also sequenced more samples of...
Pioneering new research has helped geologists solve a long-standing puzzle that could help pinpoint new, untapped concentrations of some the most valuable rare earth deposits.
Scientists from an initiative launched by the Parker Institute for Cancer Immunotherapy (PICI) and the Cancer Research Institute called the Tumor Neoantigen Selection Alliance (TESLA) have discovered parameters to better predict which neoantigens can stimulate a cancer-killing effect.
Jia and fellow researchers from Swinburne University of Technology recently teamed up with researchers from National University of Singapore, Rutgers University, University of Melbourne, and Monash University, to develop a method to generate precisely controlled graphene microbubbles on a glass surface using laser pulses.
A research team at LKS Faculty of Medicine, The University of Hong Kong (HKUMed) discovered that exosomes derived from Vδ2-T cells (Vδ2-T-Exos) can effectively control Epstein-Barr virus-associated tumours and induce T-cell anti-tumour immunity. The novel findings of Vδ2-T-Exos provide insights into new therapeutic approach for Epstein-Barr virus (EBV)-associated tumours. The...
St. Petersburg, together with colleagues from Georgia State University (USA) and Tarbiat Modares University (Tehran), have developed the HIV-PWID Policy Index (HPPI)--an international policy index for HIV prevention among people who inject drugs. This is the first major tool for assessing and comparing the extent to which HIV/AIDS prevention policies among PWID have been developed in 105...
At around 60 million light-years from Earth, the Great Barred Spiral Galaxy, NGC 1365, is captured beautifully in this image by the NASA/ESA Hubble Space Telescope.
Virologists from the KU Leuven Rega Institute in Belgium have shown that a treatment with the anti-malaria drug hydroxychloroquine does not limit SARS-CoV-2 coronavirus replication in hamsters. A high dose of the anti-flu drug favipiravir, by contrast, has an antiviral effect in the hamsters. The team published their findings in the Proceedings of the National Academy of Sciences (PNAS).
Fluctuations in the weather can have a significant impact on melting Antarctic ice, and models that do not include this factor can underestimate the global impact of sea level rise, according to Penn State scientists.
A research team at The Institute of Medical Science, The University of Tokyo (IMSUT) aimed to characterize the viral factor(s) determining immune activation upon SARS-CoV-2 infection and found that ORF3b, a gene encoded by SARS-CoV-2, is a potent IFN antagonist.
In severe cases of COVID-19, activation patterns of B cells resemble those seen in systemic lupus erythematosus, an autoimmune disease. Emory researchers want to see how far that resemblance extends.
Providing adequate personal protective equipment (PPE) for all health care workers around the world requires an initial investment of billions of dollars, but the returns on that investment could be close to 8000% in productivity gains, according to a new study published this week in the open-access journal PLOS ONE by Nicholas Risko of the Johns Hopkins University School of Medicine and...
Meltwater lakes that form at glacier margins cause ice to recede much further and faster compared to glaciers that terminate on land, according to a new study. But the effects of these glacial lakes are not represented in current ice loss models, warn the study authors. Therefore, estimates of recession rates and ice mass loss from lake-terminating glaciers in the coming decades are likely to be...
A a study carried out by scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) shows that the cardioprotective effect of metoprolol during a heart attack is not shared by other beta-blockers commonly administered by intravenous injection, such as atenolol and propranolol.
In June, two studies in Science reported an antibody cocktail against SARS-CoV-2 developed from studies in humanized mice and recovering patients.
Women are 2-3 times more likely to suffer from constipation during pregnancy and right after childbirth than at any other time in their life, a new study from the University of Eastern Finland shows.
The COVID-19 pandemic provides an opportunity to reset the global economy and reverse decades of ecosystem and species losses, but most countries are failing to invest in nature-related economic reforms or investments, according to a Rutgers-led paper.
NASA's satellite rainfall product that incorporates data from satellites and observations found that Hurricane Delta was bringing along heavy rainfall as it headed to the US Gulf Coast on Oct. 9.
