Wanted: Volunteers to catch COVID in the name of science

The world's first medical trial authorized to deliberately expose participants to the coronavirus is seeking 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 what are known as challenge trials for humans involving COVID-19.

The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review. mRNA vaccines safe during in vitro fertilization

Researchers achieve milestone on path toward nuclear fusion energy

U.S. government scientists said on Wednesday they have taken an important step in the long trek toward making nuclear fusion - the very process that powers stars - a viable energy source for humankind. Using the world's largest laser, the researchers coaxed fusion fuel for the first time to heat itself beyond the heat they zapped into it, achieving a phenomenon called a burning plasma that marked a stride toward self-sustaining fusion energy.

Scientists amazed by blinking star's 'totally unexpected' behavior

Scientists have detected what appears to be an incredibly dense star behaving unlike anything else ever seen - and suspect it might be a type of exotic astrophysical object whose existence has until now been only hypothesized. The object, spotted using the Murchison Widefield Array telescope in outback Western Australia, unleashed huge bursts of energy roughly three times per hour when viewed from Earth during two months in 2018, the researchers said.

Boosters increase protection against death from Omicron in over-50s to 95% - UKHSA

COVID-19 boosters increase protection against death from 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 any of the COVID-19 vaccines, protection against death with Omicron was around 60% in those aged 50 and over. However, this increased to around 95% two weeks after receiving a booster vaccine dose.

China's Walvax says 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 COVID-19 vaccine candidate, a senior company official said on Thursday. China has yet to approve a Chinese vaccine of the novel messenger RNA (mRNA) technology and has yet to import a foreign mRNA vaccine.
