A new paper in the prestigious journal PNAS contains a rather glaring blooper.
The paper, from Oxford University researchers Eiluned Pearce et al., is about the relationship between genes and social behaviour. The blooper is right there in the abstract, which states that "three neuropeptides (β-endorphin, oxytocin, and dopamine) play particularly important roles" in human sociality. But dopamine is not a neuropeptide.
Neither are serotonin or testosterone, but throughout the paper, Pea ...read more
Amazon and Google's dreams of delivery drones dropping off packages or pizza still face the problem of short delivery ranges. Most drones have limited battery life that restricts their services to less than a 10-mile delivery radius. A recently-approved IBM patent offers an unusual way to extend delivery ranges by having drones transfer packages in midair.
The IBM patent envisions several possible ways for delivery drones to hand off their packages without having to land. One ide ...read more
An 80-mile crack is spreading across the Antarctic Peninsula’s Larsen C ice shelf. And once that crack reaches the ocean, it will calve an iceberg the size of Delaware. The chunk looked like it could break off a few months ago, but it’s still clinging on by a roughly 10-mile thread. Earlier this week, scientists from the MIDAS project, which monitors Larsen C, reported a new branch on that crack.
Icebergs naturally calve from ice shelves all the time. But scientists are concerned th ...read more
A paper just published in Nature Human Behaviour makes some big claims about the brain. It's called Evidence for a large-scale brain system supporting allostasis and interoception in humans, but how much is evidence and how much is speculation?
The authors, Ian R. Kleckner and colleagues of Northeastern University, argue that a core function of the brain is allostasis, which they define as the process by which the brain "efficiently maintains energy regulation in the body". Allostasis ent ...read more
On Aug. 21, sky-gazers from around the world will converge in the United States as a total solar eclipse charts a path from Oregon to South Carolina. In between, on Casper Mountain in Wyoming, you’ll find Don Bruns with his telescope.
A retired physicist, Bruns is using the rare opportunity to test Albert Einstein's general relativity like Sir Arthur Eddington, who was the first scientist to test the theory back in 1919. At that time, Newton’s law of universal gravity was still vogu ...read more
