Lectures on Emergence and Complexity | Cosmic Variance

Simon DeDeo is a theoretical physicist and very smart guy, who started out as a cosmologist and has made the transition to complexity theorist at the Santa Fe Institute. (He’s not smart because he made that transition, it just so happens that both statements are true.)

Low-power optical nanotweezers may benefit cellular-level studies

(—Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power "optical nanotweezers" can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples.

Physicists make discovery about temperature in convection

An international team of physicists is working to ascertain more about the fundamental physical laws that are at work in a process known as convection, which occurs in a boiling pot of water as well as in the turbulent movement of the liquid outer core of the Earth. The team's new finding specifies the way that the temperature of a gas or liquid varies with the distance from a heat source during convection. The research is expected to eventually help engineers with applications such as the design of cooling systems, for instance, in nuclear power plants.

Spacetime ripples from dying black holes could help reveal how they formed

(—Researchers from Cardiff University have discovered a new property of black holes: their dying tones could reveal the cosmic crash that produced them.

Look at This: We Can Zoom In On Individual Molecular Bonds | 80beats

We’ve come a long way from the first glass-and-light optical microscopes. These days, scientists can focus on individual molecules using advanced methods like atomic force microscopy (AFM), where a miniscule probe feels out the details of a surface. And in this AFM image of a nanographene molecule, the resolution is so high that for the first time, we can see the individual bonds between atoms, shown here as green lines.

Dry-run experiments verify key aspect of nuclear fusion concept: Scientific 'break-even' or better is near-term goal

Magnetically imploded tubes, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests.

Experiments may reveal new state of matter for the 'glue particles', the gluons

(—At the LHC accelerator at CERN, collisions between protons and lead nuclei were established last week, for the first time in the ALICE detector.

Dry-run experiments verify key aspect of Sandia nuclear fusion concept

(—Magnetically imploded tubes called liners, intended to help produce controlled nuclear fusion at scientific "break-even" energies or better within the next few years, have functioned successfully in preliminary tests, according to a Sandia research paper accepted for publication by Physical Review Letters (PRL).

World’s most powerful digital camera opens eye, records first images in hunt for dark energy

Eight billion years ago, rays of light from distant galaxies began their long journey to Earth. That ancient starlight has now found its way to a mountaintop in Chile, where the newly-constructed Dark Energy Camera, the most powerful sky-mapping machine ever created, has captured and recorded it for the first time.

Shuttle Endeavour Ferry Flight Rescheduled to Sept. 19

NASA's ferry flight of space shuttle Endeavour atop the 747 Shuttle Carrier Aircraft (SCA) is rescheduled for Wednesday, Sept. 19 due to an unfavorable weather forecast along the flight path on Tuesday, Sept. 18. Endeavour now is expected to arrive at Los Angeles International Airport (LAX) on Friday, Sept. 21.
