Sydney, Australia | AFP | Inaudible sonic rumblings from deep in a volcano’s bowels could provide a warning when it is about to blow, scientists said Thursday, offering threatened communities the prospect of a life-saving heads-up. A team studying “infrasounds” — sounds too deep for humans to hear — from volcanoes like Italy’s Mount Etna has discovered that magmatic gurgles change markedly as an eruption nears. As magma explodes, soundwaves reverberate through the crater “just […]
Washington, United States (AFP) The months-old James Webb Space Telescope has added another major scientific discovery to its growing list: detecting for the first time signs of carbon dioxide in the atmosphere of a planet outside our solar system. Although the exoplanet would never be able to support life as we know it, the successful discovery of CO2 gives researchers hope that similar observations could be carried out on rocky objects more hospitable to […]
WASHINGTON, United States (AFP) — Dog owners know the pure joy of returning home from a long trip to be greeted by their tail-wagging, uncontrollably jumping, face-licking companion. But those ecstatic canines might be shedding more than just fur on your clothes — they might also be tearing-up, according to a new study published Monday in the journal Current Biology. “We had never heard of the discovery that animals shed tears in joyful situations, such […]
by Issam AHMED Agence France Presse WASHINGTON, United States (AFP) — It’s often said that people who click right away share “chemistry.” This expression could be true in the literal sense, according to a new study published in the journal Science Advances on Friday, which finds people with similar body odors are more likely to hit it off as friends. “Nonhuman terrestrial mammals constantly sniff themselves and each other and, based on this, decide […]
by Paola Lopez Agence France-Presse JUNIN, Ecuador (AFP) — On the banks of a crystalline waterfall, biologist Andrea Teran lets out a yelp. She holds in the palm of her hand one of two frog species at the center of a legal battle against Ecuador’s mining industry. Teran, 37, is a specialist in the fragile existence of a creature called the Resistance Rocket Frog, which does not yet have a scientific name, and the […]
by Pierre CELERIER Agence France Presse An international team of astronomers on Thursday unveiled the first image of a supermassive black hole at the centre of our own Milky Way galaxy — a cosmic body known as Sagittarius A*. The image — produced by a global team of scientists known as the Event Horizon Telescope (EHT) Collaboration — is the first, direct visual confirmation of the presence of this invisible object, and comes three years […]
by Kelly MACNAMARA Food is fundamental to the efforts to tackle climate change, according to a scientist who has spent decades tracing the interactions between global warming and what we eat. Cynthia Rosenzweig, head of the Climate Impacts Group at NASA Goddard Institute for Space Studies, was Thursday awarded the prestigious World Food Prize for her research. That includes stark warnings about the potential effect climate change will have on food. Her comments to AFP […]
by Daniel Lawler Agence France-Presse PARIS, France (AFP) – Strange lumpy terrain on Pluto unlike anything previously observed in the solar system indicates that giant ice volcanoes were active relatively recently on the dwarf planet, scientists said on Tuesday. The observation, which was made by analysing images taken by NASA’s New Horizons spacecraft, suggests that Pluto’s interior was hotter much later than previously thought, according to a new study in the Nature Communications journal. Rather than […]
WASHINGTON, D.C., United States (AFP) – Pfizer and BioNTech announced Tuesday they had formally asked the United States drug regulator for emergency approval of a second booster shot of their Covid vaccine for people aged 65 and older. The companies said in a press statement that their request is based off two Israeli studies that show “an additional mRNA booster increases immunogenicity and lowers rates of confirmed infections and severe illness.” Most countries’ case-levels have […]
by Charles ONIANS Scientists in Britain announced Wednesday they had smashed a previous record for generating fusion energy, hailing it as a “milestone” on the path towards cheap, clean power and a cooler planet. Nuclear fusion is the same process that the sun uses to generate heat. Proponents believe it could one day help address climate change by providing an abundant, safe and green source of energy. A team at the Joint European Torus (JET) […]
by Maddison Connaughton Agence France-Presse SYDNEY, Australia (AFP) – Australian researchers have discovered a strange spinning object in the Milky Way they say is unlike anything astronomers have ever seen. The object, first spotted by a university student working on his undergraduate thesis, releases a huge burst of radio energy three times every hour. The pulse comes “every 18.18 minutes, like clockwork,” said astrophysicist Natasha Hurley-Walker, who led the investigation after the student’s discovery, using […]
by Sara HUSSEIN Agence France-Presse TOKYO, Japan (AFP) – Chimpanzees in one part of Guinea crack and eat nuts while others declined to do so even when offered tools, research published on Monday found, and the difference could shed light on their culture. As humans, we are said to have cumulative culture: skills and technologies are transmitted and refined from generation to generation, producing behaviours more sophisticated than a single person could dream up. Some […]
