Washington (AFP) - Ancient viruses that infected vertebrates hundreds of millions of years ago played a pivotal role in the evolution of our advanced brains and large bodies, a study said Thursday. The research, published in the journal Cell, examined the origins of myelin, an insulating layer of fatty tissue that forms around nerves and allows electrical impulses to travel faster. According to the authors, a gene sequence acquired from retroviruses -- viruses that invade their host's DNA -- is crucial for myelin production, and that code is now found in modern mammals, amphibians and fish.

Los Angeles (AFP) - Almost 2,000 people who died during the first year of the Covid pandemic and whose bodies were never claimed were laid to rest in Los Angeles on Thursday. The cremated remains were put in a communal grave in a ceremony attended by religious and political leaders, as well as several dozen members of the public. "In 2020 sadly 1,937 residents passed away without a next of kin coming forward to claim their remains. And it is those lives that we honor... today," said LA County Supervisor Hilda Solis. "We know the desperate impact that Covid-19 had on our most vulnerable communi...

Washington (AFP) - As colder weather sets in, Covid rates are once more rising across the Northern Hemisphere, with several new variants on the scene. Here's what you need to know. Covid versus seasonal nasties?The Covid pandemic extracted a terrible toll, with nearly seven million deaths worldwide. But thanks to vaccines, prior immunity and better treatments, the virus is now far more manageable. In the United States, excess deaths -- the total number of people dying for any given cause -- has been normal since spring. "If you asked me to choose between getting flu and Covid, I would pick...

Washington (AFP) - The United States on Monday approved Covid vaccines with formulations that more closely target currently circulating variants, as infections are once more on the rise. The new approvals relate to updated vaccines produced by Moderna and Pfizer that correspond to an Omicron sublineage. The Food and Drug Administration (FDA) concluded that the benefits of receiving the shots outweighs the risk for those aged six months and up. "Vaccination remains critical to public health and continued protection against serious consequences of COVID-19, including hospitalization and death," ...

Washington (AFP) - When Joe Biden was criticized this week for failing to mask up after his wife caught Covid, he didn't just put a brave face on it. Rather, the 80-year-old US president did it again -- and then flaunted the fact that he was breaking the guidance. And by laughing it off the Democrat, who is running for re-election in 2024, showed he was in touch with Americans who are fed up with the pandemic. Biden first raised eyebrows on Tuesday by removing his mask while draping the Medal of Honor around the neck of an octogenarian Vietnam War veteran at the White House. Just hours earlier...

Geneva (AFP) - The World Health Organization declared that mpox no longer constitutes a global health emergency on Thursday, almost exactly a year after the disease formerly known as monkeypox started spreading globally. WHO chief Tedros Adhanom Ghebreyesus said the decision was prompted by sharply falling case numbers worldwide, but emphasised that the disease remains a threat, particularly in areas of Africa where it has long been endemic. The announcement comes a week after the UN agency also declared that Covid-19 no longer constitutes a public health emergency of international concern (PH...

Washington (AFP) - Though daily life has long returned to near-normal for many in the United States, the official end of the Covid-19 health emergency Thursday night still marks a new post-pandemic era for the country. Here are five key statistics about the pandemic in the United States, which has seen the most coronavirus deaths -- in absolute numbers -- of any country in the world. Three years of health emergencyA state of emergency was first declared in the United States in January 2020, more than three years ago. Authorities have spent months preparing for its eventual May 11 end. Covid...

Geneva (AFP) - The Covid-19 pandemic, which killed millions of people and wreaked economic and social havoc, no longer constitutes a global health emergency, the WHO said Friday, warning that the threat remained. It is "with great hope that I declare Covid-19 over as a global health emergency", World Health Organization chief Tedros Adhanom Ghebreyesus told reporters. The move came after the WHO's independent emergency committee on the Covid crisis agreed it no longer merited the organisation's highest alert level and "advised that it is time to transition to long-term management of the COVID-...
