Like other coronaviruses, it has transferred to humans from animals. The World Health...
Ministers call on mobile companies to send mass broadcast to reach up to 60m peopleCoronavirus – latest updatesSee all our coronavirus coverageThe UK government has taken the unprecedented step of asking mobile companies to send an alert to everyone in the UK telling them to heed the new nationwide lockdown rules.It is the first time ministers have called upon all the UK’s mobile operators –...
Millions will be able to move around the region after weeks of stringent measures to stem the spread of Covid-19Coronavirus – latest updatesSee all our coronavirus coverageTens of millions of Chinese residents living near the centre of the coronavirus outbreak will be able to resume travel from Wednesday, after authorities announced restrictions would be lifted in Hubei province, except in the...
Locals post images of spectacular orange skies, with many describing it as a welcome distraction.
Sarah Boseley speaks to Prof Deenan Pillay about how the virus contaminates surfaces and why headlines about how long it can survive may be misleading. And, following a number of listener questions, we find out whether or not Sars-CoV-2 can survive in a swimming pool Continue...
Here are some questions that all chemotherapy patients should ask their oncologistFrom a clinic emptied of patients but not their problems, I begin a series of phone consults, the first of which is to an increasingly fatigued man who lives alone. For a while I have rued the day someone suggested he have chemotherapy because now he has poured all his energies into having intensifying toxic...
Magnetic bacteria might soon be used for the production of novel biomaterials. A team of microbiologists at the University of Bayreuth led by Prof. Dr. Dirk Schüler developed a modular system for the genetic reprogramming of bacteria, thereby turning the organisms into cell factories for multifunctional magnetic nanoparticles that combine various useful functions and properties.
A research team coordinated by the University of Trento studied a mass of brain cells, the habenula, linked to disorders like autism, schizophrenia and depression. The results of their work, published in 'Development', will help find out more about serious brain disorders that can only be treated in ways that take a toll on the quality of life of people.
The study was conducted in Brazil and mapped the genes that are activated when mice resistant to Leishmania are infected. Molecules involved in the signaling pathway responsible for combating the parasite can serve as biomarkers for the evaluation of prognosis.
Biohydrogels have been studied closely for their potential use in biomedical applications, but they often move between sols and gels, depending on their temperature, changes that can pose issues depending on the intended use. In Physics of Fluids, researchers discuss their work studying the effect of temperature on hydrogels. They found that creating hydrogels at room temperature or below results...
With 3,000 known species and thousands more left to describe, the wasps of the subfamily Microgastrinae are the single most important group of parasitoids attacking the larvae of butterflies and moths, many of which are economically important pests. Consequently, these wasps have a significant impact on both the world's economy and biodiversity. All currently available information about the group...
Certain forms of epilepsy are accompanied by inflammation of important brain regions. Researchers at the University of Bonn have now identified a mechanism that explains this link. Their results may also pave the way to new therapeutic options in the medium term. They have now been published in the renowned scientific journal 'Annals of Neurology'.
A bacterial protein fragment instigates lung tissue death in pulmonary fibrosis, a mysterious disease affecting millions of people worldwide, according to a new study from researchers at the University of Illinois at Urbana-Champaign and Mie University in Japan.
From the age of 50, there is a decline not just in physical activity but also in cognitive abilities since the two are correlated. But which of them influences the other? Researchers (UNIGE) used a database of over 100,000 people aged 50-90 whose physical and cognitive abilities were measured every two years for 12 years. The findings show that cognitive abilities ward off inactivity much more...
A team of scientists, led by the University of Bristol, has developed a new photosynthetic protein system enabling an enhanced and more sustainable approach to solar-powered technological devices. The initiative is part of a broader effort in the field of synthetic biology to use proteins in place of man-made materials which are often scarce, expensive and can be harmful to the environment when...
Patients with autoimmune diseases often have an illness experience riddled with symptom ambiguities and shifting diagnoses. A new Drexel University study found that one way patients and physicians can work through the difficulty and frustration of communicating about these conditions is to use both broad diagnostic terms, like 'autoimmune disease,' as well as narrow ones, such as 'lupus or MS.'
Changes in a specific type of sugarlike molecule, or glycan, on the surface of cancer cells help them to spread into other tissues, according to researchers at UC Davis.
Perceiving warmth requires input from a surprising source: cool receptors. The finding published in Neuron by neuroscientists at the MDC challenges the theory that dedicated neurons convey either warm or cool sensations to the brain.
Eighty-four percent of the wells sampled in the Kings Mountain Belt and the Charlotte and Milton Belts of the Piedmont region of North Carolina contained concentrations of vanadium and hexavalent chromium that exceeded health recommendations from the North Carolina Department of Health and Human Services.
Coronavirus envelope all-atom computer model being developed by Amaro Lab of UC San Diego on NSF-funded Frontera supercomputer of TACC at UT Austin. Coronavirus model builds on success of all-atom infuenza virus simulations by Amaro Lab. Molecular dynamics simulations for the coronavirus model tests ran on up to 4,000 nodes, or about 250,000 of Frontera's processing cores. Full model can help...
With over 300,000 COVID-19 cases across the globe, including recent cases in Syria and the Gaza Strip, the data continues to demonstrate how the disease has no borders. A new Dartmouth-led commentary in the International Journal for Equity in Health highlights how people affected by humanitarian crises are especially vulnerable to COVID-19.
For the first time, a soft and stretchable organic thermoelectric module has been created that can harvest energy from body heat. The breakthrough was enabled by a new composite material that may have widespread use in smart clothing, wearable electronics and electronic skin. The result is published in Nature Communications.
Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient's blood or serum. But current designs need a lot of DNA. In a new study, crumpling graphene makes it more than ten thousand times more sensitive to DNA by creating electrical 'hot spots,' researchers at the University of Illinois at Urbana-Champaign found.
Nearly three in ten New York City residents (29%) report that either they or someone in their household has lost their job as a result of coronavirus over the last two weeks. In addition, 80% of NYC residents said they experienced reduced ability to get the food they need, and two-thirds (66%) reported a loss of social connection in the past week, suggesting that compelled isolation is taking a...
