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

(Phys.org)—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

(Phys.org)—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.
