Researchers at Tel Aviv University, led by Prof. Alexander Golberg of the Porter School of Environmental and Earth Sciences, have found that a substance called ulvan extracted from edible marine algae called ulva prevents the infection of cells with the Corona virus. The researchers: "This is a cheap natural material for production, which may help solve a serious problem - the spread of the Corona virus in large populations, especially in developing countries, which do not have access to the vaccine. The lack of access of vacine takes the lives of many victims and even accelerates the creation of new variants. The study is still in its early stages, but we hope that the discovery will be used in the future to develop an accessible and effective drug, preventing infection with the Corona virus."

Mortality rates for corona patients requiring mechanical ventilation is around 50%, and there are only a few effective treatment options. However, new research results indicate that a well-known drug, already being used at hospitals, could improve the course of these critically ill patients. The study has just been published in the prestigious American Journal of Respiratory and Critical Care Medicine.

ITHACA, N.Y. -- A computational tool allows researchers to precisely predict locations on the surfaces of human and COVID-19 viral proteins that bind with each other, a breakthrough that will greatly benefit our understanding of the virus and the development of drugs that block binding sites.

At the University Hospital Tübingen, clinical evaluation of an in-house developed vaccine (CoVac-1) against SARS-CoV-2 was started in November 2020 under the direction of Prof. Dr. Juliane Walz in the CCU Translational Immunology of the Medical Clinic (Medical Director Prof. Dr. Helmut Salih). Now the results of the Phase I study are available and demonstrate a potent activation of the T-cell response against the coronavirus. The results recently have been published in the renowned journal Nature. The study is currently in the second phase.

A plant-based antiviral treatment for Covid-19, recently discovered by scientists at the University of Nottingham, has been found to be just as effective at treating all variants of the virus SARS-CoV-2, even the highly infectious Delta variant.

The struggle to control the Covid-19 pandemic is made more difficult by the continual emergence of virulent SARS-CoV-2 variants, which are either more infectious, cause more severe infection, or both.

The genetic tweaks that make humans uniquely human may come in small parcels interspersed with DNA inherited from extinct ancestors and cousins.

Only 1.5 percent to 7 percent of the collective human genetic instruction book, or genome, contains uniquely human DNA, researchers report July 16 in Science Advances.

It’s hard to imagine what Earth might look like in 2500. But a collaboration between science and art is offering an unsettling window into how ongoing climate change might transform now-familiar terrain into alien landscapes over the next few centuries.

Young children’s ability to laugh and make jokes has been mapped by age for the first time using data from a new study involving nearly 700 children from birth to 4 years of age, from around the world. The findings, led by University of Bristol researchers and published in Behavior Research Methods, identifies the earliest age humour emerges and how it typically builds in the first years of life.

AstraZeneca’s antibody treatment has been shown to be highly effective at preventing Covid-19 in people who may not respond well to vaccines, according to new clinical trial results. The data showed that patients given a single injection of the antibody treatment, known as AZD7442, were 83% less likely to develop symptomatic cases of the coronavirus than participants who were given a placebo.

Disulfiram, a treatment for alcoholism, may cut severe SARS-CoV-2 infection, reduce likelihood of dying from COVID-19. For the past year and a half, the COVID-19 pandemic has continued to engulf the globe, fueled in part by novel variants and the uneven distribution of vaccines. Every day, hundreds of thousands of new COVID-19 cases and thousands of new deaths are still being reported worldwide, creating a need for drugs that can combat the disease caused by SARS-CoV-2.
