[:es]Mathematicians Find a New Class of Digitally Delicate Primes[:]
Despite finding no specific examples, researchers have proved the existence of a pervasive kind of prime number so delicate that changing any of its infinite digits renders it composite.

[:es]Earliest South American migrants had Indigenous Australian, Melanesian ancestry[:]
In 2015, scientists discovered something surprising: that some Indigenous peoples in the Brazilian Amazon were distantly—but distinctly—related to native Australians and Melanesians. The genetic signal of Australasian ancestry in so far-flung a population sent researchers scrambling for answers. A new study reveals this genetic signal is more prevalent throughout South America than thought and suggests…

[:es] Visual Illusion Reveals That Depression Can Change How We Physically See The World [:]
We know that depression is linked to variations in the way our brains are wired, but new research suggests that people who are going through a depressive episode actually see the world around them differently.

[:es]Long-Missing Midsize Black Hole Flashes Into View[:]
Black holes seemed to come only in sizes small and XXL. A new search strategy has uncovered a black hole of “intermediate” mass, raising hopes of more to come.

[:es]New generation of carbon dioxide traps could make carbon capture practical[:]
Windmills and solar panels are proliferating fast, but not fast enough to stave off the worst of climate change. Doing so, U.N. climate experts say, will also require capturing carbon dioxide (CO2) from the tens of thousands of fossil fuel power plants and industrial smokestacks likely to keep belching for years to come. Today’s most…

[:es]Matrix Multiplication Inches Closer to Mythic Goal[:]
A recent paper set the fastest record for multiplying two matrices. But it also marks the end of the line for a method researchers have relied on for decades to make improvements.

[:es]Ultrasound reads monkey brains, opening new way to control machines with thought[:]
The most advanced mind-controlled devices being tested in humans rely on tiny wires inserted into the brain. Now researchers have paved the way for a less invasive option. They’ve used ultrasound imaging to predict a monkey’s intended eye or hand movements—information that could generate commands for a robotic arm or computer cursor. If the approach…
