Wanted: Volunteers to catch COVID in the name of science

The world’s first medical trial allowed to deliberately expose participants to the coronavirus is looking for more volunteers as it steps up efforts to help develop better vaccines. The Oxford University trial was launched last April, three months after Britain became the first country to approve so-called human challenge trials involving COVID-19 .

Researchers take important step on the road to nuclear fusion power

US government scientists said on Wednesday they had taken an important step in the long journey towards nuclear fusion – the very process that powers the stars – a viable source of energy for mankind. Using the world’s largest laser, researchers for the first time coaxed fusion fuel to heat up beyond the heat they zapped from it, achieving a phenomenon called burning plasma that marked a step towards autonomous fusion energy.

UK COVID study finds record prevalence in January

An English COVID-19 study reported record prevalence in January after an Omicron-fueled spike in infections, Imperial College London said on Wednesday, adding that infections had fallen from their peak but were now leveling off. England will on Thursday drop mask mandates and COVID-19 vaccine passes introduced to slow the spread of Omicron. Prime Minister Boris Johnson has attributed the successful deployment of the UK booster to the lesser severity of the variant as he aims to live with COVID-19.

NASA’s new space telescope reaches its destination in solar orbit

NASA’s James Webb Space Telescope, designed to give the world unprecedented insight into infant galaxies in the early stages of the universe, arrived at its gravitational parking spot in orbit around the sun on Monday, nearly a million miles from Earth. With a final five-minute course-correcting push from his onboard rocket, Webb reached his destination at a position of gravitational equilibrium known as the second Sun-Earth Lagrange point, or L2, arriving a month after launch. , NASA officials said.

COVID less severe with Omicron than with Delta, US study finds

The Omicron variant appears to result in less severe COVID-19 than seen in previous periods of high coronavirus transmission, including the Delta wave, with shorter hospital stays, less need for intensive care and fewer deaths, according to a researcher. new US study. However, the fast-spreading Omicron variant has led to record numbers of infections and hospitalizations, straining the US healthcare system.

Analysis-A metaverse with Chinese characteristics is a clean and compliant metaverse

How will the Chinese metaverse evolve? Look at the letter “c”. Clean, censored, compliant, and encryption-free is the expert view. The descriptions point to the long shadow cast by Chinese authorities who have previously hinted that they will have a heavy regulatory hand over how it develops – a shadow that some defenders of the Chinese metaverse fear will stunt its growth.

Sinovac diet gets big boost from Pfizer, AstraZeneca or J&J COVID injections – study

A third booster dose of a COVID-19 vaccine made by AstraZeneca, Pfizer-BioNTech or Johnson & Johnson significantly increases antibody levels in those who have already received two doses of Sinovac’s CoronaVac vaccine, a study has found. The study found that CoronaVac received the strongest boost from a viral vector or RNA shot, including against Delta and Omicron coronavirus variants, researchers from Brazil and the United States said Monday. University of Oxford.

Pfizer, Moderna draws safely during in vitro fertilization; healthy gut bacteria may help prevent long COVID

Here is a summary of some recent studies on COVID-19. They include research that deserves further study to corroborate the findings and that has not yet been certified by peer review. mRNA vaccines are safe during in vitro fertilization

China allows GM crops to promote food safety

China has released trial rules for approving genetically modified plants, paving the way for faster crop improvements as it seeks to bolster its food security. Gene editing – or modifying a plant’s genes to change or improve its performance – is considered by some scientists to be less risky than genetically modifying them, which involves the transfer of a foreign gene.
