by Juliette Collen and Kelly Macnamara PARIS, France (AFP) — There may be far more water on the Moon than previously thought, according to two studies published Monday raising the tantalizing prospect that astronauts on future space missions could find refreshment — and maybe even fuel — on the lunar surface. The Moon was believed to be bone dry until around a decade ago, when a series of findings suggested that our nearest celestial neighbor […]

Coronavirus survives on skin five times longer than flu: study
TOKYO, Japan (AFP) — The coronavirus remains active on human skin for nine hours, Japanese researchers have found, in a discovery they said showed the need for frequent hand washing to combat the Covid-19 pandemic. The pathogen that causes the flu survives on human skin for about 1.8 hours by comparison, said the study published this month in the Clinical Infectious Diseases journal. “The nine-hour survival of SARS-CoV-2 (the virus strain that causes Covid-19) on […]
Biggest North Pole mission back from ‘dying Arctic’
by Yannick PASQUET Agence France-Presse BERLIN, Germany (AFP) — Researchers on the world’s biggest mission to the North Pole returned to Germany on Monday, bringing home devastating proof of a dying Arctic Ocean and warnings of ice-free summers in just decades. The German Alfred Wegener Institute’s Polarstern ship returned to the port of Bremerhaven after 389 days spent drifting through the Arctic trapped in ice, allowing scientists to gather vital information on the effects of […]
Unique vine ‘greenhouses’ found by 91-year-old nature volunteer
by Kelly MACNAMARA Agence France-Presse PARIS, France (AFP) — An unusual vine discovered by a 91-year-old volunteer nature guide in Japan has a “unique” way of using its leaves to curl around its fruits to envelop them in a protective microclimate, scientists said on Wednesday. The cucurbitaceous vine, a type found in East Asia, is an oddity because while leaves come in all shapes and sizes and perform a crucial role in photosynthesis, they are […]
Scientists detect mysterious ‘intermediate mass’ black hole
by Marlowe HOOD PARIS, France (AFP) — Scientists announced Wednesday the discovery of a black hole — the oldest ever detected — that shouldn’t even exist according to the current understanding of cosmic monsters so dense not even light can escape their gravitational pull. Born of a merger between two other black holes, GW190521 weighs in at 142 times the mass of our Sun and is the first “intermediate-mass” black hole ever observed, two consortiums […]
Musk shows off progress merging brains and machines
by Glenn CHAPMAN Agence France Presse Futurist entrepreneur Elon Musk late Friday demonstrated progress made by his Neuralink startup in meshing brains with computers, saying the work is essential to the future of humanity. Musk has long contended that a neural lace merging minds with machines is vital if people are going to avoid being so outpaced by artificial intelligence that, under the best of circumstances, humans would be akin to “house cats.” “It’s […]
Antarctica’s glacier-damming ice shelves at risk
by Marlowe HOOD Agence France-Presse More than half the ice shelves ringing Antarctica that prevent huge glaciers from sliding into the ocean and lifting sea levels are at risk of crumbling due to climate change, researchers said Wednesday. Melt water running into deep fissures caused by warming air is undermining the structural integrity of these natural barricades, they reported in Nature. “If the ice shelves fill up with melt water, things can happen very quickly,” […]

Small asteroid becomes closest ever seen passing Earth: NASA
WASHINGTON, United States (AFP) — An asteroid the size of an SUV passed 1,830 miles (2,950 kilometers) above Earth, the closest asteroid ever observed passing by our planet, NASA said Tuesday. If it had been on a collision course with Earth, the asteroid — named 2020 QG — would likely not have caused any damage, instead of disintegrating in the atmosphere, creating a fireball in the sky, or a meteor, NASA’s Jet Propulsion Laboratory (JPL) […]
Male Brazilian frog stays loyal to two females in ‘harem’
by Issam AHMED WASHINGTON, United States (AFP) — A species of frog from the Brazilian rainforest has become the first amphibian shown to live in a harem, where one male mates with two females who remain loyal to him. So-called polygyny is thought to be the most common mating system among animals and has previously been found in bony fishes, reptiles, mammals, birds, and even some invertebrates, Fabio de Sa, a zoologist at Universidade Estadual […]
An irresistible scent makes locusts swarm, study finds
by Sara HUSSEIN TOKYO, Japan (AFP) — The coronavirus isn’t the only plague making headlines this year — locusts are devastating crops in several parts of the world, and now scientists are discovering why the pest forms destructive swarms. On its own, a locust is fairly harmless. But so-called solitary locusts can undergo a metamorphosis, changing colour and joining together with millions of others in catastrophic clouds that strip fields. So what prompts locusts to […]
‘Baby’ Milky Way discovered 12 bln light years away
by Laurence COUSTAL PARIS, France (AFP) — A golden halo glinting 12 billion light years away is the farthest galaxy resembling our Milky Way yet spotted, astronomers said Wednesday, adding the “surprisingly unchaotic” infant star system challenges our understanding of the early years of the Universe. The galaxy, called SPT0418-47, is so far away that it took billions of years for its light to reach Earth and so our image of it is from deep […]
