New microscope collects dynamic images of the molecules that animate life
Over the last decade, powerful new microscopes have dramatically sharpened biologists' focus on the molecules that animate and propel life. Now, a new imaging platform developed by Eric Betzig and colleagues ...
Martian meteorite yields more evidence of the possibility of life on Mars
(Phys.org) —The finding of a 'cell-like' structure, which investigators now know once held water, came about as a result of collaboration between scientists in the UK and Greece. Their findings are published ...
PBS stares back at 1.8-gigapixel ARGUS drone imaging system
Flowing water on Mars appears likely but hard to prove
(Phys.org) —Martian experts have known since 2011 that mysterious, possibly water-related streaks appear and disappear on the planet's surface. Georgia Institute of Technology Ph.D. candidate Lujendra Ojha ...
Marks on Martian dunes may be tracks of dry-ice sleds
(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
Surprising clutch of hydrogen clouds discovered lurking among our galactic neighbors
(Phys.org) —In a dark, starless patch of intergalactic space, astronomers have discovered a never-before-seen cluster of hydrogen clouds strewn between two nearby galaxies, Andromeda (M31) and Triangulum ...
Dark matter filament studied in 3-D for the first time
(Phys.org)—Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3D for the first time. Extending 60 million light-years from one of the most massive galaxy ...
NASA Mars spacecraft reveals a more dynamic red planet
(Phys.org) —NASA's Mars Reconnaissance Orbiter has revealed to scientists slender dark markings—possibly due to salty water - that advance seasonally down slopes surprisingly close to the Martian equator.
Study resolves century-long debate over how to describe electromagnetic momentum density in matter
(PhysOrg.com) -- Researchers from the NIST Center for Nanoscale Science and Technology and the University of British Columbia have shown that the interaction between a light pulse and a light-absorbing object, including the ...
Computing the best high-resolution 3-D tissue images
Real-time, 3-D microscopic tissue imaging could be a revolution for medical fields such as cancer diagnosis, minimally invasive surgery and ophthalmology. University of Illinois researchers have developed ...
Researchers find new form of Mars lava flow
High-resolution photos of lava flows on Mars reveal coiling spiral patterns that resemble snail or nautilus shells. Such patterns have been found in a few locations on Earth, but never before on Mars. The ...
Winds of change strike Mars, too
Mysterious dark sand dunes around Mars' northern polar cap are shifting with the seasons, as carbon dioxide gas changes form and sparks landscape-altering avalanches, said a study published Thursday.
Meteorite shockwaves trigger dust avalanches on Mars
(PhysOrg.com) -- Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA.
NASA Mars orbiter examines dramatic new crater
(Phys.org) —Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.
