FDA officially authorizes its first Serological Antibody Blood Test for COVID-19

The FDA granted its first emergency authorization for a rapid antibody blood test for COVID-19, developed by Cellex, allowing people to gauge a person’s immune response to the novel coronavirus.

The serological test—which uses a fingerprick of blood and a small strip, similar to a combination of a blood glucose test and a home pregnancy exam—detects two different types of antibodies produced by the body to fight off the infection. Available by prescription, this can be used to determine whether a person has been previously infected and possibly recovered.

Discovery of Life in Solid Rock deep Beneath Sea may inspire new search for Life on Mars

Bacteria live in tiny clay-filled cracks in solid rock millions of years old. Newly discovered single-celled creatures living deep beneath the seafloor have given researchers clues about how they might find life on Mars. These bacteria were discovered living in tiny cracks inside volcanic rocks after researchers persisted over a decade of trial and error to find a new way to examine the rocks.

Researchers estimate that the rock cracks are home to a community of bacteria as dense as that of the human gut, about 10 billion bacterial cells per cubic cent...

Trial Drug can significantly Block Early stages of COVID-19 in engineered human tissues

An international team led by University of British Columbia 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 today 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 lives of 50,000 people worldwide.

The study provides new insights into key aspects of SARS-CoV-2, the virus that causes COVID-19, and its interactions on a cellular level, as well as how the virus can infect blood vessels and kidneys.

‘Tequila’ powered Biofuels more Efficient than Corn or Sugar

Ethanol from agave could be used for transport fuel and hand sanitizer. The agave plant used to make tequila could be established in semi-arid Australia as an environmentally friendly solution to Australia’s transport fuel shortage, a team of researchers at the University of Sydney, University of Exeter and University of Adelaide has found.

The efficient, low-water process could also help produce ethanol for hand sanitiser, which is in high demand during the COVID-19 pandemic.

In an article published this week in the Journal of Cleaner Production, University of Sydney agronomist Associate Professor Daniel Tan with international and Australian colleagues have analysed the potential to produce bioethanol (...
