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 .
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 They include research that deserves further study to corroborate the findings and that has not yet been certified by peer review.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
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.
Scientists amazed by ‘totally unexpected’ behavior of blinking star
Scientists have detected what appears to be an incredibly dense star unlike anything else they’ve ever seen – and suspect it could be a type of exotic astrophysical object whose existence hasn’t existed until now. at present been only hypothetical. The object, spotted using the Murchison Widefield Array telescope in outback Western Australia, fired huge bursts of energy about three times an hour when viewed from Earth during two months in 2018, the researchers said.
Boosters increase Omicron death protection in over-50s to 95% – UKHSA
COVID-19 boosters increase the death protection of the Omicron variant to 95% in people aged 50 or over, the UK Health Security Agency said on Thursday. The UKHSA said that around six months after the second dose of one of the COVID-19 vaccines, protection against death with Omicron was around 60% in people aged 50 and over. However, this figure rose to around 95% two weeks after receiving a booster dose of the vaccine.
China’s Walvax says it has most participants for large mRNA COVID vaccine trial
China’s Walvax Biotechnology has recruited most of the 28,000 participants needed for a large clinical trial of its mRNA vaccine candidate against COVID-19, a senior company official said Thursday. China has not yet approved a Chinese new messenger RNA (mRNA) technology vaccine and has not yet imported a foreign mRNA vaccine.
