Venus Was Wet: A Measurement of the Ratio of Deuterium to Hydrogen
The deuterium-hydrogen abundance ratio in the Venus atmosphere was measured while the inlets to the Pioneer Venus large probe mass spectrometer were coated with sulfuric acid from Venus' clouds. TheExpand
Cosmic Ripples Confirm Universe Speeding Up
Four years ago, cosmologists announced that the universe appears to be expanding at ever-increasing speed--and that a mysterious antigravity force must be doing the pushing. Now an internationalExpand
Quantum Spookiness Wins, Einstein Loses in Photon Test
Among quantum theory9s oddest claims is that the states of two particles or photons can influence each other no matter how far apart they are, providing their quantum states are "entangled." AExpand
Astronomers Tame a Workhorse Laser
Techniques for controlling chaos—a hair-trigger sensitivity to initial conditions—have enabled a group of researchers to stabilize a tunable infrared laser. The feat, reported onp page 1498, may beExpand

TLDR
So-called "neuromorphic engineers" are adapting the tricks that the nervous system has come up with over the course of evolution to build a new kind of computer that captures in silicon the "essence" of biological subsystems. Expand
Hubble Successor Gathers Support
NASA scientists have unfurled a blueprint for an ambitious new project: a $500 million successor to the Hubble Space Telescope that will peer in the infrared back to the early stages of galaxyExpand
Oxides of nitrogen and the clouds of Venus
Nitric Oxide may be produced in the atmosphere of Venus by lightning storms in the clouds. Here we suggest that the odd nitrogen thus formed may play an important part in the chemistry of the clouds.Expand
Antimatter: Physicists Produce First Anti-Atom
Researchers at CERN, the European center for particle physics in Geneva, have unveiled a piece of a looking-glass world by creating the first atoms of antimatter. Last fall they painstakinglyExpand

TLDR
In the realm of the very small, measurements lose their certainty, and materials don't behave as they should, so researchers are exploiting the oddities of the nanoworld to make new measuring devices. Expand
`Eraser' Rubs Out Information to Reveal Light's Dual Nature
Cambridge, U.K.—A team of physicists in Austria has provided new experimental confirmation for one of the more bizarre predictions of quantum mechanics: The behavior of one photon in a pair canExpand
