NASA Administrator Visits Houston, Meets Media

NASA Administrator Charles Bolden will be at the agency's Johnson Space Center in Houston on Thursday, May 16, to discuss the future of human space exploration and the critical role the International Space Station performs in support of those efforts.

NASA's Google+ Hangout Connects Space Station, "Star Trek Into Darkness" Crews

The director and some actors in the film "Star Trek Into Darkness" will join NASA as it hosts a Google+ Hangout from noon to 12:45 p.m. EDT, May 16, about how work aboard the International Space Station is turning science fiction into reality.

NASA Honors Sally Ride with a National Tribute at Kennedy Center

NASA and Sally Ride Science are inviting the general public and journalists to "Sally Ride: A Lifetime of Accomplishment, A Champion of Science Literacy," an educational tribute to America's first woman in space on Monday, May 20. The special event will be held at the John F. Kennedy Center for the Performing Arts, 2700 F Street, N.W., Washington, D.C., at 7 p.m. EDT.

Physicists light 'magnetic fire' to reveal energy's path

New York University physicists have uncovered how energy is released and dispersed in magnetic materials in a process akin to the spread of forest fires, a finding that has the potential to deepen our understanding of self-sustained chemical reactions.

The mechanism that puts the curl in the curling stone revealed

Researchers from Uppsala University in Sweden can now reveal the mechanism behind the curved path of a curling stone. The discovery by the researchers, who usually study friction and wear in industrial and technical applications, is now published in the scientific journal Wear.

Manipulating Lorentz and Fano spectral line shapes

( —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short pulses in the attosecond range at very high power can now be used to probe and control nanostructures like photonic crystals, metal hole arrays, and conductance in quantum dots. The light absorption spectrum of a material reveals critical details about its microstructure.

Chaos could improve performance of wireless communication systems

( —In today's wireless communication systems, the wireless signals are non-chaotic, meaning they have a well-defined period and frequency. Non-chaotic wireless signals are used in many applications, such as satellite communications, GPS navigation, cell phones, and Wi-Fi devices. However, as many people know first-hand, wireless systems usually have inferior performance compared to wired systems. The problem is due to physical impediments that the wireless signal faces in open space caused by the atmosphere, water, mountains, buildings, and other different media.

Photonic quantum computers: A brighter future than ever

Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists have succeeded in prototyping a new and highly resource efficient model of a quantum computer -- the boson sampling computer.

Solar panels as inexpensive as paint?

Researchers are helping develop a new generation of photovoltaic cells that produce more power and cost less to manufacture than what's available today.

Space Station Expedition 35 Astronauts Land Safely in Kazakhstan, Expedition 36 Begins

Three members of the International Space Station Expedition 35 crew undocked from the orbiting laboratory and returned safely to Earth Monday, May 13, wrapping up a mission lasting almost five months. The departure marks the beginning of Expedition 36.
