Immune system T cell responses to variants remain potent Scientists warn of rebound after record 7% fall in global emissions Coronavirus restrictions led to a record 7% fall in global carbon emissions last year, but the drop will be short-lived unless efforts to phase out fossil fuel are intensified, a study by scientists in the journal Nature Climate Change said.

Following is a summary of current science news briefs. South African scientists find antibodies from variant may offer cross-protection

Research by South African scientists suggests that antibodies triggered by exposure to the country's dominant coronavirus variant can prevent infection by other variants, the scientists said on Wednesday. The findings in laboratory studies offer hope that COVID-19 vaccines based on the 501Y.V2 variant first identified late last year could protect against multiple variants circulating in different parts of the world. Maezawa wants you: Japan billionaire seeks 'crew' for moon trip

Japanese billionaire Yusaku Maezawa on Wednesday launched a search for eight people to join him as the first private passengers on a trip around the moon with Elon Musk's SpaceX. He had originally planned to invite artists for the weeklong voyage slated for 2023. Graphic: Bats and the origins of outbreaks

Scientists have long suspected that the rate of new infectious diseases could accelerate, especially in developing countries where human and animal interaction is increasing. Changes in the environment are driving displaced species of animals into new habitats, allowing them to mix with other species or potential hosts. T cell response to virus variants remains potent; Asthma does not raise severe COVID-19 risk

The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. Immune system T cell responses to variants remain potent Scientists warn of rebound after record 7% fall in global emissions

Coronavirus restrictions led to a record 7% fall in global carbon emissions last year, but the drop will be short-lived unless efforts to phase out fossil fuel are intensified, a study by scientists in the journal Nature Climate Change said. The study by scientists from institutions in Australia, Britain, France, Norway and the United States, confirmed preliminary estimates from May last year that global CO2 emissions from fossil fuels fell by 7%, or 2.6 billion tonnes, to 34 billion tonnes. SpaceX Starship rocket prototype nails landing... then blows up

The third time appeared to be the charm for Elon Musk's Starship rocket - until it wasn't. The latest heavy-duty launch vehicle prototype from SpaceX soared flawlessly into the sky in a high-altitude test blast-off on Wednesday from Boca Chica, Texas, then flew itself back to Earth to achieve the first upright landing for a Starship model.
