Mutations in SARS-CoV-2 offer insights into virus evolution

By analyzing virus genomes from over 7,500 people infected with COVID-19, researchers have characterized patterns of diversity of SARS-CoV-2 virus genome, offering clues to direct drugs and vaccine targets. The study identified close to 200 recurrent genetic mutations in the virus, highlighting how it may be adapting and evolving to its human hosts.

Antibody blocks infection by the SARS-CoV-2 in cells, scientists discover

Researchers report that they have identified a fully human monoclonal antibody that prevents the SARS-CoV-2 (COVID-19) virus from infecting cultured cells. The discovery is an initial step towards developing a fully human antibody to treat or prevent the respiratory disease COVID-19 caused by the novel coronavirus SARS-CoV-2.

Antibodies from llamas could help in fight against COVID-19, study suggests

Researchers linked two copies of a special kind of antibody produced by llamas to create a new antibody that binds tightly to a key protein on the coronavirus that causes COVID-19. This protein, called the spike protein, allows the virus to break into host cells. Initial tests indicate that the antibody blocks viruses that display this spike protein from infecting cells in culture.

4-billion-year-old nitrogen-containing organic molecules discovered in Martian meteorites

Scientists exploring Mars and analysing Martian meteorite samples have found organic compounds essential for life: nitrogen-bearing organics in a 4-billion-year-old Martian meteorite. With a new high-spatial resolution in-situ N-chemical speciation technique, they found organic materials -- either synthesized locally or delivered during the Noachian -- preserved intact in carbonate minerals over a long geological period. Their presence requires abiotic or biotic N-fixation and ammonia storage, suggesting early Mars had a less oxidizing environment than today.

Scientists regenerate neurons in mice with spinal cord injury and optic nerve damage

Each year thousands of patients face life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed. New research in mice shows, however, that gains in functional recovery from these injuries may be possible, thanks to a molecule known as Lin28, which regulates cell growth.
