NASA Selects Science Instrument and Hardware for European Mission to Jupiter

NASA has selected key contributions to a 2022 European Space Agency (ESA) mission that will study Jupiter and three of its largest moons in unprecedented detail. The moons are thought to harbor vast water oceans beneath their icy surfaces.

Investing in Technology to Enable the Future: NASA Creates Space Technology Mission Directorate

As part of the Obama Administration's recognition of the critical role that space technology and innovation will play in enabling both future space missions and bettering life here on Earth, NASA Administrator Charles Bolden has announced the creation of the Space Technology Mission Directorate.

NASA Student Mars Project Wins Education Award

A NASA project that allows students to use a camera on a spacecraft orbiting Mars for research has received a new education prize from the journal Science.

Cornell physicist and Nobel winner Richardson dies

Robert C. Richardson, a Cornell University professor who shared a Nobel Prize for a key discovery in experimental physics, has died. He was 75.

Potential benefits of inertial fusion energy justify continued R&D

The potential benefits of successful development of an inertial confinement fusion-based energy technology justify investment in fusion energy research and development as part of the long-term U.S. energy R&D portfolio, says a new report from the National Research Council. Although ignition of the fusion fuel has not yet been achieved, scientific and technological progress in inertial confinement fusion over the past decade has been substantial.

The Case for Building a Death Star

I got a call yesterday from a producer at Fox News, who asked me if I wanted to comment on a proposal by two California physicists to build a "Death Star" that would protect our planet from incoming asteroids. The answer to a question like that is inevitably going to be "Of course!" so I appeared on Fox News earlier this morning to discuss the idea. (View the story here.)

The proposal, which was announced by press release and press conference, comes from cosmologist Philip Lubin of the Un

New technology in the magnetic cooling of chips

Researchers from CICnanoGUNE and the University of Cambridge have developed a new technology in the magnetic cooling of chips based on the straining of materials. Compared with the current technologies, this advance enables the impact on the environment to be lessened. The work has been published recently in the prestigious journal Nature Materials.

Probing ultrafast solvation dynamics with high repetition-rate laser / X-ray methodologies

The chemical reactivity of molecules in solution critically depends on a complex interplay among intramolecular processes and interactions with the caging solvation shell, which surrounds a solute molecule. Accordingly, the influence of solvation on the reactivity of chemical and biological molecular species has been the subject of increasingly intense research. Ultrafast time-resolved x-ray measurement techniques that combine picosecond lasers and short-pulse x-rays in laser pump/x-ray probe experiments are powerful tools for studying this interplay in photo-active molecular systems.

Quantum dots that assemble themselves

Scientists have demonstrated a process whereby quantum dots can self-assemble at optimal locations in nanowires, a breakthrough that could improve solar cells, quantum computing, and lighting devices.
