Clues to a possible cure for AIDS

Decades into the epidemic, the numbers for AIDS are still awful. In a report published on July 22nd, UNAIDS, the United Nations agency tasked with dealing with the disease, says that 40m people around the world are now infected. There were 1.3m new HIV infections in 2023, and 630,000 HIV-related deaths. But those two numbers

H5N1 avian flu could cause a human pandemic

ON JULY 14TH America’s Centres for Disease Control and Prevention (CDC) reported five new cases of the H5N1 avian flu virus in humans, bringing the total number of cases reported since April to nine. All five were involved in culling infected poultry in Colorado, and appear to have the same strain that has been spreading

Astronomers have found a cave on the moon

FROM AN ESTATE agent’s perspective, the lunar surface has little to recommend it. Its none-too-metaphorical lack of atmosphere means it is bombarded by meteorites, cosmic radiation is unrelentingly harsh and temperatures range from lows of -246°C to highs of 121°C. Subsurface lunar caves, on the other hand, with stable temperatures and cover from projectiles, would

Freeze-dried chromosomes can survive for thousands of years

For palaeontologists, DNA is infuriatingly fragile. Its long chains begin to break apart shortly after death, destroying valuable information about the deceased parent organism. Unlike bones, footprints and even faecal matter, which can comfortably survive—in fossilised form—for millions of years, DNA rarely lasts much more than a hundred. In recent decades scientists have discovered that

Vaccines could keep salmon safe from sea lice

ERIK SLINDE has spent 40 years developing vaccines. Not for humans; for salmon. “Back in the 1980s, it was looked upon as a joke,” says Dr Slinde, the former director of aquacultural research at the Institute of Marine Research in Norway. Nobody is laughing now. Sea lice—rice-grain-sized crustaceans that have evolved to parasitise salmon fish
