Any new coronavirus vaccine that works well and is safe will still have the daunting challenge of needing to be produced to scale in a very short amount of time. It will also have to be safely delivered into the hands of the most remote populations. The more complex and untested the vaccine approach, the more difficult it will be to both scale its production and deliver it around the world. By…
Scientists at Sanford Burnham Prebys have found a new way to kill pancreatic cancer cells by disrupting their pH equilibrium. The study, published in Cancer Discovery, reports how depleting an ion transport protein lowers the pH to a point that compromises pancreatic cancer cell growth. Pancreatic cancer cells—like all cancer cells—have a constant need for energy to support their growth and…
Students from EPFL in Switzerland teamed up with startup IcosaMed to develop the SmartBra – the first piece of smart clothing that can be used for cancer prevention. “Our smart-clothing technology is designed to detect cancer at the earliest stages. It uses a non-invasive, painless method based on frequent ultrasound monitoring,” says Hugo Vuillet, one of the students on the development…

Dr Alan Parker and his team, whose work on…
In a small clinical trial just granted approval, about 30 COVID-19 patients at Karolinska University Hospital may soon begin to receive blood plasma from people who have recovered from the disease. Sweden's Ethical Review Authority has approved the trial treatment, and its effectiveness will be evaluated in a study by researchers at Karolinska Institutet and the Karolinska University Hospital.…
People who are at high risk of developing lung cancer, such as heavy smokers, are routinely screened with computed tomography (CT), which can detect tumors in the lungs. However, this test has an extremely high rate of false positives, as it also picks up benign nodules in the lungs. Researchers at the Massachussetts Institute of Technology (MIT) have now developed a new approach to early…
The causes of 40 percent of all cases of certain medulloblastoma – dangerous brain tumors affecting children – are hereditary. A genetic defect that occurs in 15 percent of these children plays a key role by destabilizing the production and breakdown of proteins. The researchers suspect that protein metabolism defects could be a previously underestimated cause of other types of cancer.
In a new study, researchers found that half of the patients they treated for mild COVID-19 infection still had coronavirus for up to eight days after symptoms disappeared. The research letter was published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.
Mathematical models can help shed light on the evolution of the coronavirus pandemic, according to Spanish mathematician Juan Luis Fernández Martínez, who predicted Spain could have between 90,000 and 160,000 infected patients. The next trend in epidemic data science will be to issue prediction models that focus on early detection.
The production of highly sensitive sensors is a complex process: it requires many different steps and the almost dust-free environment of special cleanrooms. A research team from Materials Science at Kiel University (CAU) and from Biomedical Engineering at the Technical University of Moldova has now developed a procedure to produce extremely sensitive and energy-efficient sensors using 3D…
Sepsis—the body's own immune response gone against it—is a major health problem worldwide. It is basically a "hyper" immune response by the body to infection or injury, and is characterized by hyperinflammation, immune system paralysis, cell death, liver and kidney failure, blood clots, and even hemorrhage. An estimated 30 million people suffer from sepsis every year, of which 20%…
Countries where people do not have a habit of washing their hands automatically tend to have a much higher exposure to coronavirus, a new study reveals. University of Birmingham researchers have discovered that at least 50% of people do not have a habit of automatic handwashing after using the toilet in China (77%), Japan (70%), South Korea (61%) and the Netherlands (50%). These countries are…
University of Massachusetts Amherst researchers have invented a portable surveillance device powered by machine learning – called FluSense – which can detect coughing and crowd size in real time, then analyze the data to directly monitor flu-like illnesses and influenza trends. The FluSense creators say the new edge-computing platform, envisioned for use in hospitals, healthcare waiting rooms…
The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine. The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three…
Media reporting of suicide, especially celebrity suicides, is associated with increases in suicide in the general population, particularly by the same method as used by the celebrity, finds an analysis of the latest evidence published by The BMJ. The researchers say their findings support the continued use and promotion of guidelines on responsible media reporting of suicide, especially when…
As coronavirus disease COVID-19 continues to jet and alight invisibly around the globe, scientists now report that the virus has mutated to become two strains: the older ‘S-type’ appears milder and less infectious, while the later-emerging ‘L-type’, is more aggressive, spreads more quickly, and currently accounts for about 70 per cent of cases. Worldwide, medical researchers are exploring…
An international team of researchers from the University of Zurich, the University Hospital Zurich, Heidelberg and Glasgow has identified a novel function for the cell death regulating protein MCL1: It is essential in protecting the intestine against cancer development – independent of bacterial-driven inflammation. These findings have implications for the use of MCL1 inhibitors, currently…
