by Marlowe HOOD PARIS, France (AFP) — At least one running argument among cat lovers is now over: Whiskers, Lucy and Tigger are definitely better off staying indoors, scientists reported Wednesday. Pet cats allowed outdoors, in fact, are nearly three times as likely to become infected with pathogens or parasites than those confined to quarters, they reported in the Royal Society journal Biology Letters. Two-legged house-mates should also take note because cats — a.k.a. Felis […]
by Delphine Matthieussent TEL AVIV, Israel (AFP) — Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels on Monday, calling it a first and a “major medical breakthrough” that advances possibilities for transplants. While it remains a far way off, scientists hope one day to be able to produce hearts suitable for transplant into humans as well as patches to regenerate defective hearts. The heart produced by researchers at […]
NEW YORK, United States (AFP) — Anonymous to the public just days ago, a US computer scientist named Katie Bouman has become an overnight sensation due to her role in developing a computer algorithm that allowed researchers to take the world’s first image of a black hole. “I’m so excited that we finally get to share what we have been working on for the past year!” the 29-year-old Bouman, a postdoctoral researcher at the Harvard-Smithsonian […]
by Marlowe Hood and Laurence Coustal PARIS, France (AFP) — Astronomers on Wednesday unveiled the first photo of a black hole, one of the star-devouring monsters scattered throughout the Universe and obscured by impenetrable shields of gravity. The image of a dark core encircled by a flame-orange halo of white-hot plasma looks like any number of artists’ renderings over the last 30 years. But this time, it’s the real deal. “The history of science will […]
by Kang Jin-kyu Agence France Presse SEOUL, South Korea (AFP) — South Korea launches the world’s first fully-fledged 5G mobile networks Friday, a transformational leap that already has superpowers sparring for control of an innovation that could potentially change the day-to-day lives of billions of people. The superfast communications heralded by fifth-generation wireless technology will ultimately underpin everything from toasters to telephones; from electric cars to power grids. But while the South has won […]
WASHINGTON, United States (AFP) — NASA has captured unprecedented photos of the interaction of shockwaves from two supersonic aircraft, part of its research into developing planes that can fly faster than sound without thunderous “sonic booms”. When an aircraft crosses that threshold — around 1,225 kilometers (760 miles) per hour at sea level — it produces waves from the pressure it puts on the air around it, which merge to cause the ear-splitting sound. […]
PARIS, France (AFP) — Astronomers said Thursday they had accurately calculated the mass of the Milky Way for the first time, using new data sets that include the weight of dark matter. In a collaboration between NASA and the European Space Agency’s Gaia observation craft, a team of experts calculated our galaxy to be around 1.5 trillion solar masses. Previous estimates put the mass of the Milky Way ranging between 500 billion and 3 trillion […]
by Sara HUSSEIN Agence France-Presse TOKYO, Japan (AFP) — For years, insecticide-soaked mosquito nets have helped dramatically lower malaria infections, but insecticide resistance has driven a search for alternatives and a new study may have uncovered one option. The weapon is a familiar one: an anti-malarial drug already used by humans to prevent them contracting the disease, and researchers now envisage using it on netting like insecticides. Their research shows the drug works on mosquitoes, […]
by Marlowe HOOD Agence France-Presse PARIS, France (AFP) — Marine clouds that protect us from hothouse Earth conditions by reflecting sunlight back into space could break up and vanish if CO2 in the atmosphere triples, researchers warned Monday. “Our results show that there are dangerous climate change thresholds of which we were unaware,” Tapio Schneider, a scientist at the Jet Propulsion Laboratory in Pasadena, California and lead author of a study detailing the findings, told […]
WASHINGTON, United States (AFP) — Every spring, the largest animals in the world, blue whales, migrate from their winter breeding grounds off of Costa Rica to the coast of the Pacific Northwest of the United States. They are in search of their favorite food, the tiny crustaceans known as krill. Scientists have long tracked the migration of the behemoths, which can weigh well over 100 tons, but could not explain how they chose their itinerary. […]
by Kyoko HASEGAWA Agence France-Presse TOKYO, Japan (AFP) — A Japanese probe sent to collect samples from an asteroid 300 million kilometers away for clues about the origin of life and the solar system landed successfully on Friday, scientists said. Hayabusa2 touched down briefly on the Ryugu asteroid, fired a bullet into the surface to puff up dust for collection and blasted back to its holding position, said officials from the Japan Aerospace Exploration Agency […]
by Kyoko HASEGAWA Agence France Presse TOKYO, Japan (AFP) — A Japanese probe is expected to land on a distant asteroid Friday, aiming to blast a “bullet” into the surface to collect clues about the origins of Earth and the solar system. The Hayabusa2 probe is scheduled to touch down at 8:25 am local time (2325 GMT Thursday) on the Ryugu asteroid, some 300 million kilometers from the Earth, according to officials at the Japan […]
