Scientists have revealed new insights into the behaviour of black holes with research that demonstrates how a phenomenon called backreaction can be simulated.
The team from the University of Nottingham have used their simulation of a black hole, involving a specially designed water tank, for this latest research published in Physical Review Letters. This study is the first to demonstrate that the evolution of black holes resulting from the fields surrounding them can be simulated in a laboratory experiment.
As COVID-19 spread across the world, so did conspiracy theories and false information about the virus. This proliferation of misinformation--labeled an "infodemic" by the World Health Organization (WHO)--makes it difficult to identify trustworthy sources and can threaten public health by undermining confidence in science, governments, and public health recommendations.
The COVID-19 pandemic is straining health systems across the country, especially intensive care units. New research from the U.S. Department of Veterans Affairs, Regenstrief Institute and Indiana University School of Medicine shows that people treated in the ICU for COVID-19 are twice as likely to die when the ICU capacity is strained by the number of COVID-19 patients.
Chronic stress could be the prevailing condition of our time. In the short term, our jaws or stomachs may clench; in the long term, stress can lead to metabolic disease and speed up diseases of aging, as well as leading to more serious psychological disorders. The physical manifestations of stress originate in the brain, and they move along a so-called "stress axis" that ends in the adrenal glands. These glands then produce the hormone cortisol.
Scientists say stable seafood consumption amongst the world's poorer coastal communities is linked to how local habitat characteristics influence fishing at different times of the year.
In the coastal communities of low-income countries, the seafood people catch themselves is often a main food source. In a new study, scientists focused on an often-overlooked type of fishing called gleaning: collecting molluscs, crabs, octopus and reef fish by hand close to shore.
(Boston)--There have been great advances in treating melanoma over the past five years, however, even with these treatments many patients quickly develop drug resistance and die from their disease. A new study from Boston University School of Medicine (BUSM) has discovered that a drug (YK-4-279) that was previously created to target one specific type of protein has much broader use against a family of proteins that act to promote melanoma.
There is a considerable gap in our current understanding of gift-giving because much of what has been studied has focused on gift-giving as an affair between just two consumers--a single giver and a recipient.
Oncotarget recently published "Simvastatin is a potential candidate drug in ovarian clear cell carcinomas" which reported that based on previous studies, the authors assessed the anti-proliferative effect of simvastatin, a Rho GTPase interfering drug, in three OCCC cell lines: JHOC-5, OVMANA and TOV-21G, and one high-grade serous ovarian cancer cell line, Caov3.
COLUMBUS, Ohio - A new deep-learning model that can predict how human genes and medicines will interact has identified at least 10 compounds that may hold promise as treatments for COVID-19.
All but two of the drugs are still considered investigational and are being tested for effectiveness against hepatitis C, fungal disease, cancer and heart disease. The list also includes the approved drugs cyclosporine, an immunosuppressant that prevents transplant organ rejection, and anidulafungin, an antifungal agent.
Over the past century, a wide variety of models have emerged to explain the complex behaviours which unfold within atomic nuclei at low energies. However, these theories bring up deep philosophical questions regarding their scientific value. Indeed, traditional epistemological tools have been rather elaborated to account for a unified and stabilised theory rather than to apprehend a plurality of models. Ideally, a theory is meant to be reductionist, unifying and fundamentalist.
Theoretical physicists of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz are working on a theory that goes beyond the Standard Model of particle physics and can answer questions where the Standard Model has to pass - for example, with respect to the hierarchies of the masses of elementary particles or the existence of dark matter. The central element of the theory is an extra dimension in spacetime. Until now, scientists have faced the problem that the predictions of their theory could not be tested experimentally.
Decoy protein intercepts spike of coronavirus
Virus prevented from infecting human cells
Protein may be new way to treat and prevent COVID-19
CHICAGO --- Northwestern Medicine scientists have developed a new protein that acts as a trickster to neutralize the COVID-19 infection in a human kidney organoid, a miniature organ made from stem cells in the lab.
Social media is increasingly used to spread fake news. The same problem can be found on the capital market - criminals spread fake news about companies in order to manipulate share prices. Researchers at the Universities of Göttingen and Frankfurt and the Jožef Stefan Institute in Ljubljana have developed an approach that can recognise such fake news, even when the news contents are repeatedly adapted. The results of the study were published in the Journal of the Association for Information Systems.
The adoption of recommended changes in concussion management led to a reduction in the length of symptoms among 11- to 18-year-old athletes with first-time, sports-related concussions, according to new research in the Journal of Osteopathic Medicine. These outcomes support the widespread adoption of the updated concussion guidelines.
NEW YORK, NY (Feb. 1, 2021)--Errors in the way chromosomes are packed into antibody-producing B cells appear to play a role in the development of B cell-related blood cancers, according to a new study by researchers at Columbia University Vagelos College of Physicians and Surgeons.
The findings could lead to new biomarkers for predicting the onset of these cancers and to a new class of cancer therapies that prevent or correct harmful changes in genome architecture.
The study was published online Feb. 1 in the journal Nature Genetics.
