Renault wants to be carbon neutral in Europe by 2040 and all over the world just 10 years later. To get there, it’s doubling down on battery-powered electric vehicles while insisting there’s still a future for hydrogen cars. Dubbed as a demo car, the Emblème is actually both. Much like the new Honda CR-V e:FCEV, it combines a hydrogen fuel cell with a rechargeable battery pack. The French marque calls it a shooting brake although some would argue it has too many doors. Body style aside, the Emblème is an aero-driven concept with a drag coefficient of only 0.25. It looks substantially…

Betelgeuse, Betelgeuse! The red supergiant that marks Orion’s left shoulder may have a tiny, unseen companion. Two independent studies found evidence of a star about the same mass as the sun, orbiting Betelgeuse about once every 2,100 days. “It was very surprising,” says astrophysicist Morgan MacLeod of the Harvard & Smithsonian Center for Astrophysics in Cambridge, Mass. If the star is real, “it’s kind of hidden right there in plain sight.” MacLeod and colleagues linked a six-year cycle of Betelgeuse brightening and dimming to a companion star tweaking its orbit, in a paper submitted to arXiv.org September 17. MacLeod examined…

Dolphins are known for what appear to be big, contagious smiles. But do they actually, well, smile? The answer, according to a new study of dolphin play, is a resounding “maybe.” Dolphins use their smile-like facial expression when interacting with their mates during playful times, researchers report October 2 in iScience. That, the team says, suggests the cetaceans are doing something akin to a human laugh. But other experts urge caution in attributing humanlike behavior to creatures whose intent we can only guess at.

Clostridioides difficile is a notoriously nasty intestinal bug, with few effective treatments and no approved vaccines. But the same technology that enabled the first COVID-19 vaccines has shown early promise, in mouse experiments, against this deadly infection, which kills 30,000 people in the United States each year. An mRNA vaccine designed to target C. difficile and the toxins it produces protected mice from severe disease and death after exposure to lethal levels of the bacterial pathogen, researchers report in the Oct. 4 Science. While it will take much more research to see whether the vaccine is safe and effective for…

House Democrats are bashing Israeli leaders over the vast expansion of settlements in the occupied West Bank, arguing the developments are not only illegal but will also make it impossible to negotiate any long-term peace deal in the Middle East. The West Bank settlements, which have grown dramatically under the right-wing government of Prime Minister Benjamin Netanyahu, have flown largely under the radar since the start of the Israel-Hamas War a year ago, overshadowed by the intensity of the conflict in Gaza – and more recently in Lebanon – where Israel has focused its military response to Hamas’s terrorist attacks…

Elsbeth Reality Shock Season 1 Episode 3 Editor’s Rating 4 stars **** Photo: CBS The second of a back-to-back set of new episodes, “Reality Shock” gives us scarcely any forward motion for Elsbeth’s DOJ-mandated investigation of potential corruption in her assigned precinct, but a bit like Hansel and Gretel following the path of stones in the moonlight, Elsbeth’s eye for shiny and tenaciously clinging glitter eventually leads her where she really needs to go. Our murder victim of the week is Wendy Wexler (Nadia Dajani), electrocuted in her tub with one of her own personally-branded blenders (Wendy’s Blendies!) after trying…

Around 2.5 million years ago, an asteroid may have exploded over Antarctica.  The evidence comes from a chemical analysis of more than 100 tiny pieces of rock entrained within the White Continent’s ice, researchers report in the Feb. 1 Earth and Planetary Science Letters. The timing makes the midair detonation the oldest known airburst, the team says. Only two other ancient airburst events are known in the geologic record, dating to 480,000 and 430,000 years ago (SN: 3/31/21).   The surfaces of Earth and other rocky bodies are littered with conspicuous craters caused by direct hits from asteroids or comets (SN:…

A genetic parasite may have robbed humans and other apes of their tails. Around 25 million years ago, this parasite, a small stretch of repetitive DNA called an Alu element, ended up in a gene important for tail development, researchers report in the Feb. 29 Nature. The single insertion altered the gene Tbxt in a way that seems to have sparked one of the defining differences between monkeys and apes: Monkeys have tails, apes don’t. “It was like lightning struck once,” says Jef Boeke, a geneticist at New York University Langone Health, and ape behinds ultimately became bare. The genetic…
