Spider webs yield clues to stickier glues

November 18, 2015 10:22 am | by American Chemical Society | Comments

Spider webs are notoriously sticky. Although they only take a second to swat down, shaking them off your hands can be an exercise in frustration. But that stubborn tackiness could come in handy when designing smart synthetic adhesives that could work even in the most humid conditions. In ACS Nano, scientists report new insight toward that goal.


Physicists uncover mechanism that stabilizes plasma within tokamaks

November 18, 2015 8:06 am | by Raphael Rosen, Princeton Plasma Physics Laboratory Communications | Comments

A team of physicists at the Princeton Plasma Physics Laboratory has discovered a mechanism that prevents the electrical current flowing through fusion plasma from repeatedly peaking and crashing. This behavior is known as a "sawtooth cycle" and can cause instabilities within the plasma's core.


Bringing more memory to quantum communication

November 18, 2015 7:59 am | by Yale Univ. | Comments

Quantum technology holds a great deal of promise, since it can potentially solve problems much faster or transfer information more secure than current technologies. But a number of obstacles stand in the way of it being used in a practical way.


Protein curbs spread of prostate cancer to bone

November 18, 2015 7:50 am | by Anne M. Stark, Lawrence Livermore National Laboratory | Comments

Scientists from Lawrence Livermore National Laboratory, in collaboration with researchers from Univ. of California campuses at Merced and Davis, have found that a specific secreted protein inhibits prostate cancer metastasis to bone. Their research appears in PLOS ONE and Microarrays.


Large-scale modeling shows confinement effects on cell macromolecules

November 18, 2015 7:41 am | by John Toon, Georgia Institute of Technology | Comments

Using large-scale computer modeling, researchers have shown the effects of confinement on macromolecules inside cells and have taken the first steps toward simulating a living cell, a capability that could allow them to ask “what-if” questions impossible to ask in real organisms.


Chemists create adaptable metallic-cage gels

November 18, 2015 7:24 am | by Anne Trafton, MIT News Office | Comments

Massachusetts Institute of Technology chemists have created a new material that combines the flexibility of polymer gels with the rigid structure provided by metal-based clusters. The new gels could be well-suited for a range of possible functions, including drug release, gas storage or water filtration, the researchers say.


In Asia, Obama says climate action will be good for business

November 17, 2015 11:00 pm | by Kathleen Hennessey, Associated Press | Comments

Weeks away from a deadline, President Barack Obama sought to build momentum Wednesday for a potentially legacy-burnishing global climate change agreement by arguing that bold climate action will be a boon for businesses in Asia and around the world.


NASA Awards Humanoid Robots to Two Universities

November 17, 2015 3:20 pm | by Greg Watry, Digital Reporter | Comments

NASA has awarded two universities prototypes of its R5 humanoid robot for advanced research and development work, the space agency announced today.


The Weight of Wings: How Bats Land Upside Down

November 17, 2015 3:16 pm | by Greg Watry, Digital Reporter | Comments

It’s a characteristic signature. Bats roost upside down, dangling from branches and any other area they can grip their feet around.


U.S. startup challenges Japan to giant robot battle

November 17, 2015 1:41 pm | by Terrence Cha, Associated Press | Comments

They've been popularized in movies, television and video games, but giant fighting robots still haven't left the realm of science fiction. That will soon change.


Google antsy as California slow on self-driving car rules

November 17, 2015 1:37 pm | by Justin Pritchard, Associated Press | Comments

The tech titan wants the freedom to give the public access to self-driving prototypes it has been testing on public roads since the summer. Before granting that permission, California regulators want Google to prove these cars of the future already drive as safely as people.


Researchers develop flexo-electric nanomaterial

November 17, 2015 1:32 pm | by Univ. of Twente | Comments

Researchers at the University of Twente's MESA+ research institute, together with researchers from several other knowledge institutions, have developed a 'flexo-electric' nanomaterial. The material has built-in mechanical tension that changes shape when you apply electrical voltage, or that generates electricity if you change its shape.


Electrons always find a (quantum) way

November 17, 2015 9:53 am | by Univ. of Basel | Comments

Scientists have demonstrated for the first time how electrons are transported from a superconductor through a quantum dot into a metal with normal conductivity. This transport process through a quantum dot had already been calculated theoretically in the nineties, but scientists have now succeeded in proving the theory with measurements.


Measuring a Galaxy’s Heartbeat

November 17, 2015 9:40 am | by Greg Watry, Digital Reporter | Comments

Astronomers from the Harvard-Smithsonian Center for Astrophysics have detected the galaxy’s heartbeat, a series of thousands of stellar pulses. The new measurements provide scientists with a new way for determining a galaxy’s age.


Accelerating fusion research through the cutting edge supercomputer

November 17, 2015 9:35 am | by National Institutes of Natural Sciences | Comments

For the first time in the world, using the newly installed "Plasma Simulator" we have simulated deuterium plasma turbulence in the Large Helical Device (LHD). From this result, we have clarified that the energy confinement in a deuterium plasma is improved in comparison to a hydrogen plasma.
