Today I started reading Neil De Grasse Tyson’s new book, Astrophysics for People in a Hurry. I’m enjoying it. It’s just enough science for my brain not to freeze up. To the scientist, the universality of physical laws makes the cosmos a marvelously simple place. By comparison, human nature—the psychologist’s domain—is infinitely more daunting. In […]
Researchers create first viable hybrid human-pig embryo: Researchers have created a viable hybrid part-human, part-pig embryo for the first time in history. According to a study published in the journal Cell Thursday, researchers were able to successfully inject human stem cells into a pig embryo and grow tissue that would form the early stages of […]
Light-based computers are on the horizon: “The phase speed is infinite—much larger, infinitely larger than the speed of light,” Mazur tells Quartz. This doesn’t mean light itself is traveling faster than the speed of light, which would violate the laws of relativity. “Phase velocity” refers to the speed of the crest of waves that ripple […]
Gizmodo: Physicists Discover “Hidden Chaos” Lurking Everywhere: It appears that the standard tools used to identify chaotic signatures might be missing lots of hidden chaos — especially in systems that seem like they’re not chaotic at all. Chaos theory is famously associated with so-called “strange attractors,” marked by a telltale butterfly-wing shape (see above). But […]
Researchers have grown a partially functioning rat limb in a lab. Really.
What could be the most important scientific experiment of our lifetime is about to begin. The so-called Holometer Experiment at the Fermi National Accelerator Laboratory aims to determine whether our perception of a three-dimensional universe is just an illusion. Do we actually live on a 2D plane, as a holographic projection? There is a well-established […]
—George Carlin This one deserves a repost.
Sure, we’ve got the iPhone’s Siri, and the Food and Drug Administration just approved a prosthetic arm controlled by signals from the brain — but where are our smooth-gliding flying machines, our Landspeeders (“Star Wars”) and airborne DeLoreans (“Back to the Future”)? You may think that the absence of such cars speaks to a failure […]
Stephanie Smith, writing for NBC affiliate KXAN in Austin, Texas on a scan that may detect brain disease in the brains of NFL players: An insidious, microscopic protein that has been found in the brain tissue of professional football players after death may now be detectable in living people by scanning their brains. Researchers say […]
TechHive: AT&T will buy mobile spectrum from Verizon for $1.9 billion It fascinates me sections of the electromagnetic spectrum are buyable. I assume I shouldn’t as we can buy land. Will the visible spectrum ever be monetized? Will companies ever try to own red, blue or green light waves?
NASA doesn’t have one of the prettiest sites on the internet, but it is the most dynamic and vital among American government sites. A little digging and a user can unearth all sorts of treasures. A great one is the Apollo 11 Image Library, which features high and low quality scans of almost every single […]
From Nature.com (via The Atlantic): Bioengineers have made an artificial jellyfish using silicone and muscle cells from a rat’s heart. The synthetic creature, dubbed a medusoid, looks like a flower with eight petals. When placed in an electric field, it pulses and swims exactly like its living counterpart. Science is crazy.
