A new way to deliver therapeutic proteins inside the body uses an acoustically sensitive carrier to encapsulate the proteins and ultrasound to image and guide the package to the exact location required, according to Penn State researchers.
A receptor in the cell layer that lines the blood vessels from the inside stimulates both the formation of new blood vessels in tumors and metastasis.
NEC Corporation announced analysis results from efforts using AI prediction platforms to design blueprints for SARS-CoV-2 vaccines that can drive potent T-cell responses in the majority of the global population. This initiative by the scientific teams within the NEC Group to help combat outbreaks of COVID-19 and support international vaccine development efforts is led by NEC OncoImmunity (NOI) in…
Two specific cell types in the nose have been identified as likely initial infection points for COVID-19 coronavirus. Scientists discovered that goblet and ciliated cells in the nose have high levels of the entry proteins that the COVID-19 virus uses to get into our cells. The identification of these cells by researchers from the Wellcome Sanger Institute, University Medical Centre Groningen,…
A team of researchers from Empa, ETH Zurich and Zurich University Hospital has succeeded in developing a novel sensor for detecting the new coronavirus. In future it could be used to measure the concentration of the virus in the environment - for example in places where there are many people or in hospital ventilation systems. Jing Wang and his team at Empa and ETH Zurich usually work on…
Scientists at the University of Cambridge have found an association between living in an area of England with high levels of air pollution and the severity of COVID-19, the disease caused by the SARS-CoV-2 virus. Because of the urgent need to share information relating to the pandemic, the researchers have published their report on MedRXiv. It has not yet been peer-reviewed. However, the…
Experts at the University of Tokyo have identified a new protein in the pathway that leads to Alzheimer’s disease. Researchers used the “molecular scissors” of CRISPR/Cas9 to search for new genes related to the neurodegenerative disease. The exact causes of Alzheimer’s disease remain unknown, but one of the most well- supported theories focuses on a protein called amyloid beta.…
Aspirin is associated with a reduction in the risk of developing several cancers of the digestive tract, including some that are almost invariably fatal, such as pancreatic and liver cancers.
Researchers from The Irish Longitudinal Study on Ageing (TILDA) at Trinity College Dublin have released a crucial report in response to the COVID-19 pandemic.
Researchers from Cambridge, UK, and Germany have reconstructed the early “evolutionary paths” of COVID-19 in humans – as infection spread from Wuhan out to Europe and North America – using genetic network techniques.
The number of cases tested positive for COVID-19 initially grew exponentially in China, but then slowed down. Dirk Brockmann, professor at Humboldt-Universität zu Berlin (HU) and project group leader at the Robert Koch-Institut (RKI), and his postdoc Benjamin F. Maier have developed a diffusion model that takes into account the effect of social distancing and other measures to explain this…
In order for a COVID-19 vaccine and antiviral drugs to be developed, scientists first need to understand why this virus spreads so easily and quickly, and why it invades our bodies with seemingly little resistance from our immune system. To understand how COVID-19 enters the body and does its damage, a team of top researchers from universities, hospitals and the National Research Council of…
Depression is a common psychiatric disorder and one of the leading causes of disability worldwide. Antidepressants are the first-line treatment for moderate to severe major depressive episodes. Despite their effectiveness, only 40% of patients respond to the first antidepressant they try. A recent paper in Nature Communication strongly suggests that a particular protein, GPR56, is involved in the…
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…
A group of scientists, physicians, funders, and policy makers from over 70 institutions from over 30 countries have launched an international coalition to respond to COVID-19 in resource-poor settings. The COVID-19 Clinical Research Coalition aims to accelerate desperately needed COVID-19 research in those areas where the virus could wreak havoc on already-fragile health systems and cause the…
An international team led by University of British Columbia (UBC) researcher Dr. Josef Penninger has found a trial drug that effectively blocks the cellular door SARS-CoV-2 uses to infect its hosts. The findings, published in Cell, hold promise as a treatment capable of stopping early infection of the novel coronavirus that, as of April 2, has affected more than 981,000 people and claimed the…
An antibody recovered from a survivor of the SARS epidemic in the early 2000s has revealed a potential vulnerability of the new coronavirus at the root of COVID-19, according to a study from scientists at Scripps Research. The study, published in Science, is the first to map a human antibody’s interaction with the new coronavirus at near-atomic-scale resolution. Although the antibody was…
A team of Cardiff University scientists has switched from researching cancer to work that could help towards a vaccine for coronavirus. The team at the School of Medicine usually work on reprogramming viruses so they can target and kill cancer - but are now focusing their efforts to help in the fight against the new virus which is gripping the world. 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.
