Earth’s purported ‘nearest black hole’ isn’t a black hole
The nearest black hole to Earth isn’t a black hole at all. Instead, what scientists thought was a stellar triplet — two stars and a black hole — is actually…
Core memory weavers and Navajo women made the Apollo missions possible
The historic Apollo moon missions are often associated with high-visibility test flights, dazzling launches and spectacular feats of engineering. But intricate, challenging handiwork — comparable to weaving — was just…
50 years ago, Arecibo got an unprecedented view of Venus’ surface
Probing Venus’ mountains — Science News, February 12, 1972 Venus’ perpetually cloud-shrouded surface remains penetrable only by radio waves. A planetary radar group now reports results of an extended series…
Earth has a second known ‘Trojan asteroid’ that shares its orbit
A recently found space rock is schlepping along with Earth around the sun. This “Trojan asteroid” is only the second one discovered that belongs to our planet. And it’s probably…
50 years ago, scientists were genetically modifying mosquitoes
Sterility gene for mosquito control — Science News, December 18, 1971 Scientists are working hard to find a substitute for DDT in the control of malaria vector mosquitoes.… Two experiments…
Some deep-sea octopuses aren’t the long-haul moms scientists thought they were
Octopuses living in the deep sea off the coast of California are breeding far faster than expected. The animals lay their eggs near geothermal springs, and the warmer water speeds…
A new gravity sensor used atoms’ weird quantum behavior to peer underground
The best way to find buried treasure may be with a quantum gravity sensor. In these devices, free-falling atoms reveal subtle variations in Earth’s gravitational pull at different places. Those…
‘From Data to Quanta’ defends Niels Bohr’s view of quantum mechanics
From Data to QuantaSlobodan PerovićUniv. of Chicago, $45 Ever since Max Planck introduced the idea of the quantum to the world, physicists have argued about whether reality is more like…
The quantum ‘boomerang’ effect has been seen for the first time
Some quantum particles gotta get right back to where they started from. Physicists have confirmed a theoretically predicted phenomenon called the quantum boomerang effect. An experiment reveals that, after being…
