Mars-bound NASA rover adjusts course to red planet (Update)
Firing on all engines, NASA's latest rover to Mars executed a course adjustment Wednesday that put it on track for a landing on the red planet in August.
Self-sacrifice among strangers has more to do with nurture than nature
(PhysOrg.com) -- Socially learned behavior and belief are much better candidates than genetics to explain the self-sacrificing behavior we see among strangers in societies, from soldiers to blood donors to ...
Venus Express unearths new clues to the planet's geological history
(Phys.org) -- ESA's Venus Express has been used to study the geology in a region near Venus' equator. Using near-infrared observations collected by the Venus Monitoring Camera (VMC), scientists have found ...
Temperatures measured at Gale Crater higher than expected
(Phys.org)—Preliminary weather reports from the Curiosity's Remote Environment Monitoring Station (REMS) are showing some surprisingly mild temperatures during the day. Average daytime air temperatures ...
Study reveals seasonal patterns of tropical rainfall changes from global warming
Projections of rainfall changes from global warming have been very uncertain because scientists could not determine how two different mechanisms will impact rainfall. The two mechanisms turn out to complement ...
Sounding rockets study how winds in space drive currents in the upper atmosphere
Some 50 miles up in the sky begins a dynamic region of the atmosphere known as the ionosphere. The region is filled with charged particles created by extreme ultraviolet radiation from the sun. At the base ...
Virtual laboratory predicts train vibrations
The construction of new rail lines, or the relocation of old ones underground, has increased society's interest over recent years in the vibrations produced by trains, especially among people who live or work ...
Gale before Curiosity: What we knew and what the rover may reveal
The first comprehensive analysis of what we knew about the Gale crater on Mars before the recent landing of space rover Curiosity has been published by the International Journal of Astrobiology (IJA).
Biophysicists model the behavior of a protein critical to cell motion
(Phys.org) -- Physicists at Lehigh have created a mathematical model that could benefit researchers who study cell motion, including cancerous cell motion, tissue healing processes and human embryonic development.
Taming the Boltzmann equation
Physicists at Ludwig Maximilian University of Munich, Germany, have developed a new algorithm that is capable of solving the Boltzmann equation for systems of self-propelled particles. The new method also ...
From smart grids to flying robots, engineer finds many applications for theory
The future of electricity involves a "smart" grid, in which the energy distribution system is fully computerized, with sensors and wireless devices monitoring remote parts of the system and communicating ...
Researchers use cell 'profiling' to detect abnormalities -- including cancer
An Ohio State University mathematician and his colleagues are finding ways to tell the difference between healthy cells and abnormal cells, such as cancer cells, based on the way the cells look and move.
Chasing clouds on Venus
(Phys.org)—Clouds regularly punctuate Earth's blue sky, but on Venus the clouds never part, for the planet is wrapped entirely in a 20 km-thick veil of carbon dioxide and sulphuric dioxide haze.
Meeting consumers' HD demands with a faster algorithm
(PhysOrg.com) -- Engineers help smaller processors outperform a single superfast processor by working more efficiently in parallel.
