As much of Europe is engulfed by a second wave of Covid-19, and track and trace struggles to meet demand, modelling support tools are being increasingly used by policymakers to make key decisions. Most notably, models have been used to predict the Covid-19 R0 rate - the average rate of secondary infections from a single infection, which has formed the basis for many lockdown decisions across the UK.
Time crystals sound like something out of science fiction, but they may be the next major leap in quantum network research. A team based in Japan has proposed a method to use time crystals to simulate massive networks with very little computing power.
They published their results on October 16 Science Advances.
A new study led by Marc Veldhoen, principal investigator at Instituto de Medicina Molecular João Lobo Antunes (iMM; Portugal) with an interdisciplinary team of clinicians and researchers from Faculdade de Medicina da Universidade de Lisboa (FMUL) and Centro Hospitalar Lisboa Norte (CHLN) and collaborators at Instituto Português do Sangue e Transplantação (IPST), shows that 90% of subjects have detectable antibodies 40 days up to 7 months post contracting COVID-19.
Researchers at National University of Science and Technology MISIS (NUST MISIS) have managed to develop a unique method to process bulk metallic glasses. According to the authors of the study, they have managed to find processing conditions that significantly improve the quality of this promising material. The research results were published in Journal of Alloys and Compounds.
During human evolution, the size of the brain increased, especially in a particular part called the neocortex. The neocortex enables us to speak, dream and think. In search of the causes underlying neocortex expansion, researchers at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, together with colleagues at the University Hospital Carl Gustav Carus Dresden, previously identified a number of molecular players.
Sponges are filter feeders that live on particulate matter - but they can also ingest microscopic fragments of plastics and other pollutants of anthropogenic origin. They can therefore serve as useful bioindicators of the health of marine ecosystems.
Findings from the largest international research study found that using FIT is almost 100% accurate at ruling out bowel cancer in patients with suspicious symptoms.
The study has just been published in Gut, and the research already won prestigious top prizes of the two main surgical societies in the UK.
Conventional plastic is made from oil. The production of plastic is not sustainable, and it can contain substances we know are dangerous if ingested.
In recent years, bioplastics have come onto the market as an alternative to conventional plastic. Bioplastic has some apparent advantages: it is usually made from recycled material or plant cellulose, it can be biodegradable - or both.
But a new study shows that it is not non-toxic.
Bioplastics are in fact just as toxic as other plastics, according to an article recently published in Environment International.
Bottom Line: Younger patients with resected melanoma had some benefit from adjuvant treatment with the anti-VEGF therapeutic bevacizumab (Avastin) while older patients with resected melanoma did not.
Preclinical data showed that VEGF, a protein that promotes angiogenesis and is the target of bevacizumab, decreased with age, and was superseded by the protein sFRP2 in promoting angiogenesis.
Journal in Which the Study was Published: Clinical Cancer Research, a journal of the American Association for Cancer Research
Extreme events occur in many observable contexts. Nature is a prolific source: rogue water waves surging high above the swell, monsoon rains, wildfire, etc. From climate science to optics, physicists have classified the characteristics of extreme events, extending the notion to their respective domains of expertise. For instance, extreme events can take place in telecommunication data streams.
Recent FDA chief Dr. Scott Gottlieb argued that he'd "rather try to get everyone in masks" and "try to get them in high-quality masks because we know it's going to slow down the transmission."
Against this backdrop, a new study published in Risk Analysis, "Reinventing cloth masks in the face of pandemics," by Stephen Salter, P.Eng., describes how Effective Fiber Mask Programs (EFMPs) can help communities find a balance between the economy and curbing community spread.
A study from Winship Cancer Institute of Emory University (Winship) has the potential to change how patients whose prostate cancer recurs after prostatectomy are treated. The study will be featured in both the plenary session and press program of the American Society for Radiation Oncology (ASTRO) Annual Meeting on Monday, October 26.
LAWRENCE -- A team led by an astronomer from the University of Kansas has crunched data from NASA's TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of exoplanet dubbed a "hot Neptune."
N-heterocycles are organic substances used in the chemical industry and medicine. To produce them, expensive catalysts made from noble metals are used. A chemist from RUDN University developed a nanocatalyst for N-heterocycles that consists of zinc oxide and niobium and can be obtained using orange peel without any additional chemical agents. The catalyst makes the reaction almost 100% effective, thus increasing the efficiency and reducing the cost of N-heterocycles production. The results of the study were published in the Catalysis Today journal.
LA JOLLA, CA--Scientists from Scripps Research and Los Alamos National Laboratory have devised a method for mapping in unprecedented detail the thickets of slippery sugar molecules that help shield HIV from the immune system.
Mapping these shields will give researchers a more complete understanding of why antibodies react to some spots on the virus but not others, and may shape the design of new vaccines that target the most vulnerable and accessible sites on HIV and other viruses.
