Very subtle control of artificial limbs by means of a tiny electronic device may become possible.… [The] electronic device … [is] designed to be injected into a muscle through a thick hypodermic needle. A tiny package strapped to the outside of the limb will beam radio waves at the device, which will return them, modified by the electric current produced in the muscle. — ...
Immanuel Kant was famous for writing critiques.
He earned his status as the premier philosopher of modern times with such works as Critique of Pure Reason, Critique of Practical Reason and Critique of Judgment. It might have been helpful for medical science if he had also written a critique of evidence.
Scientific research supposedly provides reliable evidence for physicians to...
In a last-ditch effort to save a dying 7-year-old boy, scientists have used stem cells and gene therapy to replace about 80 percent of his skin.
This procedure’s success demonstrates that the combination therapy may be effective against some rare genetic skin disorders. The study also sheds light on how the skin replenishes itself, researchers report November 8 in Nature.
Alligators don’t just stick to freshwater and the prey they find there. These crafty reptiles can live quite easily, at least for a bit, in salty waters and find plenty to eat — including crabs, sea turtles and even sharks.
“They should change the textbooks,” says James Nifong, an ecologist with the Kansas Cooperative Fish and Wildlife Research Unit at Kansas State University in...
Finding the chemical basis for the close association between the Attine ants, inhabiting an area extending from Argentina to the southern United States, and the fungus they culture is the aim of research … by Prof. Michael M. Martin of the University of Michigan. Although many animals feed on fungi, the culturing of fungus by the Attine ants is the only known example of...
Net to halt runaway airliners
A gigantic emergency arresting gear system, capable of stopping the largest four-engined jet aircraft without discomfort to passengers, is being developed for the French Ministry of Transportation. The system consists of a nylon net … which engages the aircraft for the full width of its wingspan. Net and airplane are brought to a slow stop by energy...

It’s possible that therapies such as external brain stimulation and neurofeedback, as well as some drugs, may one day boost brain flexibility. A new line of research suggests flexibility is important for learning, Laura Sanders reported in “Learning takes brain acrobatics” (SN: 9/16/17, p. 22).
Online reader Glenn wondered if drugs for Parkinson’s disease and Huntington’s...
Jennifer Zaspel can’t explain why she stuck her thumb in the vial with the moth. Just an after-dark, out-in-the-woods zing of curiosity.
She was catching moths on a July night in the Russian Far East and had just eased a Calyptra, with brownish forewings like a dried leaf, into a plastic collecting vial. Of the 17 or so largely tropical Calyptra species, eight were known vampires. Males...
No other science engages human curiosity like astronomy. From antiquity onward, attempts to comprehend the architecture of the cosmos have commanded a substantial fraction of humankind’s mental budget for intellectual endeavor. Only in the last century, though, have astronomers grasped the structure of the cosmos accurately. Just a hundred years ago, a great debate raged about the fuzzy...
A seaweed-like marine invertebrate contains a molecule that has piqued interest as a drug but is in short supply: Collecting 14 tons of the critters, a type of bryozoan, yields just 18 grams of the potential medicine. Now, an efficient lab recipe might make bryostatin 1 easier to get.
Making more of the molecule could help scientists figure out whether the drug — which has shown mixed...
