In a nifty experiment involving movement-mimicking robots and a brief time delay, scientists uncover a potential neurological basis for sensing ghostly phenomena. “The mismatched sensory and motor information confused their brains…If those…didn’t match up, my brain would revise its perception of reality to account for the discrepancies. Maybe I’m not inside my body at all, it might think. Maybe I’m over there.”
Scared and smarter: In an experiment right out of the The Secret of NIMH, researchers discover that mice learn faster after being given a gene linked to human speech. ‘What surprised me most was that the humanized gene actually improved the animal’s behavior rather than messing up the system.'” Remember…Dubya did try to warn us.
Citing various recent research, Vox’s Joseph Stromberg extols the benefits of the coffee nap. “So if you nap for those 20 minutes, you’ll reduce your levels of adenosine just in time for the caffeine to kick in. The caffeine will have less adenosine to compete with, and will thereby be even more effective in making you alert.” And just imagine how much more fulfilling a Red Bull-Guinness-Coffee-Nap would be.
Take that, Van Helsing: Per PBS’s NOVA, research increasingly suggests that transfusions of young blood hold the secret to slowing or reversing aging. “We can turn back the clock instead of slowing the clock down,” said Dr. Toren Finkel, director of the Center for Molecular Medicine at the National Heart, Lung and Blood Institute.”
(Unless, of course, it’s all about the jellyfish.)
Among the most frightening developments in a world full of bad news at the moment: Ebola is running rampant through West Africa, and has reached both Freetown and Lagos, Africa’s largest city (where it was hopefully and quickly contained.) “This epidemic…can only get worse, because it is still spreading, above all in Liberia and Sierra Leone, in some very important hotspots,’ Janssens said…’we have never known such an epidemic.'”
Still, before you seal the locks on the underground shelter, the general scientific consensus seems to be that, even if the virus does reach here by plane — and it may well — ebola isn’t influenza circa 1918: “This is not a highly transmissible disease, where the number of people who can be infected by a single individual is high. You have to come into very close contact with blood, organs, or bodily fluids of infected animals, including people. If you educate people properly and isolate those who are potentially infected, it should be something you can bring under control.”
Also, as far as deadly mutations go, ebola “kill[s] so quickly that I don’t envision there’s going to be a major shift in transmission.” Some small comfort…unless, of course, you’re infected. As it is, per The Onion, a vaccine is “at least 50 white people“ away.
As written up by Aatish Bhatia at Wired, the winners of Princeton’s annual Art of Science competition are announced. “Among the entries are some wonderful ‘oops’ moments, where an experiment goes beautifully wrong, revealing art where you might not have expected to see it…But most of these submissions aren’t accidents. Many of these pieces reveal form, structure, and beauty hidden at a scale that our eyes can’t perceive.”
In an impressive breakthrough, biologists successfully expand the genetic alphabet of a living organism from four to six, opening up all kinds of possibilities for everything from pharmaceuticals to new life. “‘This is a very major accomplishment in our efforts to inch towards a synthetic biology,’ says Steven Benner, a synthetic biologist at the Foundation for Applied Molecular Evolution who was not involved in the study. ‘Many in the broader community thought that Floyd’s result would be impossible to achieve.'”
Sorry, Lenny: A new study finds a potentially problematic issue for decades of research: Mice are scared of men (or males of any species). ‘If you’re doing a liver cell study, the cells came from a rat that was sacrificed either by a man or a woman,’ Mogil says. As a result, ‘its stress levels would be in very different states.’ This, he says, could have an effect on the functioning of the liver cell in that later experiment.”
In The Atlantic, Alexis Madrigal unearths the amazing secrets, and industry, surrounding horseshoe crab blood. “The thing about the blood that everyone notices first: It’s blue, baby blue…The iron-based, oxygen-carrying hemoglobin molecules in our blood give it that red color; the copper-based, oxygen-carrying hemocyanin molecules in theirs make it baby blue.”
