How do we terraform Venus?
It might be possible to terraform Venus some day, when our technology gets good enough. The challenges for Venus are totally different than for Mars. How will we need to fix Venus?
Commercial Dream Chaser closer to critical design review and first flight
The winged Dream Chaser mini-shuttle under development by Sierra Nevada Corp. (SNC) has successfully completed a series of risk reduction milestone tests on key flight hardware systems thereby moving the ...
Mysterious dance of dwarfs may force a cosmic rethink
(Phys.org) —The discovery that many small galaxies throughout the universe do not 'swarm' around larger ones like bees do but 'dance' in orderly disc-shaped orbits is a challenge to our understanding of ...
Squink personal factory aims to make circuit prototyping easy
Material generates steam under solar illumination
A new material structure developed at MIT generates steam by soaking up the sun.
Earth survived near-miss from 2012 solar storm: NASA
Back in 2012, the Sun erupted with a powerful solar storm that just missed the Earth but was big enough to "knock modern civilization back to the 18th century," NASA said.
NASA Mars spacecraft prepare for close comet flyby
NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars on Oct. 19.
US plans widespread seismic testing of sea floor
(AP)—The U.S. government is planning to use sound blasting to conduct research on the ocean floor along most of the East Coast, using technology similar to that which led to a court battle by environmentalists in New Jersey.
Transiting exoplanet with longest known year
Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus ...
Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread ...
Bacteria manipulate salt to build shelters to hibernate
For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and is left to dry, b ...

First in-situ images of void collapse in explosives
While creating the first-ever images of explosives using an x-ray free electron laser in California, Los Alamos researchers and collaborators demonstrated a crucial diagnostic for studying how voids affect ...
The first supercomputer simulations of 'spin–orbit' forces between neutrons and protons in an atomic nucleus
Protons and neutrons are held together at the center of an atom by powerful nuclear forces. A theory that can describe the interaction between just two of these subatomic particles could potentially be extended ...
