Bugs on Mars
Undaunted by the hurdles on flight posed by thin air and a lack of oxygen, aerospace engineers are devising extraordinary flying machines resembling giant insects and windmills to make the exploration of Mars more rapid and effective.
- Tech
Live Tour: Joystick journeys reveal tumor interiors
A new holographic technique may someday enable doctors to skip certain biopsies and choose instead to take video excursions inside suspicious growths in skin or internal body linings.
- Physics
Unexpected Boost: A superconductivity killer’s silver lining
Among superconductors—materials able to conduct electricity without resistance—an effect that normally diminishes current-carrying ability surprisingly turns out to sometimes enhance it.
- Astronomy
Physics-astronomy merger wins big
A new report recommends fostering the extraordinary collaboration taking place between particle physics and astronomy.
- Physics
Detector spots solar chameleons
A new measurement of the sun's emission of ghostly neutrinos indicates that the prevailing theory of particle physics needs repair.
- Physics
Not-So-Neutral Neutron: Clearer view of neutron reveals charged locales
A sharp, new picture of the neutron reveals that rather than being uniformly electrically neutral, the particle contains regions of positive and negative charge.
- Astronomy
Strange Stars? Odd features hint at novel matter
Two stellar corpses thought to be made of neutrons may actually contain weird forms of matter never observed before.
- Physics
Molding Atoms: Using a tiny template to make tinier structures
With the help of a molecular mold composed of exactly 188 atoms, researchers have been able to impose textures at an even smaller atomic scale on a metal surface.
- Materials Science
Osmium is Forever: Rare metal’s strength humbles mighty diamond’s
A new route to materials harder than diamond may have opened with the surprising finding that the rare metal osmium resists compression better than diamond does.
- Health & Medicine
X rays tell stirring tale about fat
X rays reveal how food processing shapes microscopic crystals of edible fats.
- Tech
Sowing neat rows of seeds on silicon
A new way to introduce foreign atoms into silicon with atomic-scale precision may help chip manufacturers over a looming hurdle.
