Twin detectors recently installed in the first of three experimental halls in the Daya Bay Reactor Neutrino Experiment are now recording interactions of elementary antineutrinos produced by powerful reactors at the China Guangdong Nuclear Power Group power plant located about 55 kilometers from Hong Kong.

China and the U.S. lead the Daya Bay Reactor Neutrino Experiment, which also includes participants from Russia, the Czech Republic, Hong Kong, and Taiwan and the event marks the first step in the international effort to measure a puzzling property of neutrinos and antineutrinos that may underlie basic properties of matter and why matter predominates over antimatter in the universe.

Four new studies have found that when a woman's goal is to be romantically desirable, she is less likely to go into majors and activities related to science, technology, engineering and math (STEM).  The studies were undertaken to determine why women, who have achieved parity in education, getting more Ph.D.s than men, and also in the workplace, continue to be underrepresented at the highest levels of STEM fields.

They found converging support for the idea that when romantic goals are activated women (but not men) show less interest in STEM fields and more interest in feminine fields, such as the humanities, education and social sciences.

New nano-structured glass optical elements could significantly reduce the cost of medical imaging.

In their Applied Physics Letters paper, the team describes how they have used nano-structures to develop new monolithic glass space-variant polarization converters. These millimeter-sized devices generate ‘whirlpools’ of light enabling precise laser material processing, optical manipulation of atom-sized objects, ultra-high resolution imaging and maybe even table-top particle accelerators. 

A giant cosmic necklace glows brightly in this NASA Hubble Space Telescope image of an object named (surprise) the Necklace Nebula, a recently discovered planetary nebula which is the glowing remains of an ordinary, Sun-like star. 

The nebula consists of a bright ring, measuring 12 trillion miles across, dotted with dense, bright knots of gas that resemble diamonds in a necklace. The knots glow brightly due to absorption of ultraviolet light from the central stars.

The Necklace Nebula is located 15,000 light-years (4,600 parsecs) away in the constellation Sagitta (the Arrow). In this composite image, taken on July 2, 2011, Hubble's Wide Field Camera 3 captured the glow of hydrogen (blue), oxygen (green), and nitrogen (red).

One of the earliest lessons science students learn is that a beam of light travels in a straight line and fan out, or diffract, as they travel. Recently it was discovered that light rays can travel without diffraction in a curved arc in free space. These rays of light were dubbed “Airy beams,” after the English astronomer Sir George Biddell Airy, who studied what appears to be the parabolic trajectory of light in a rainbow.

Now, scientists with the Lawrence Berkeley National Laboratory have demonstrated the first technique that provides dynamic control in real-time of the curved trajectories of Airy beams over metallic surfaces.

Assuming you don't have the space for a smelly compost heap but want to be as environmentally responsible as possible, what’s the most responsible way to dispose of a banana peel, or any other food waste?

A new study about the impact of various food waste disposal systems says putting it into a garbage disposer results in lower global warming potential than putting it in the trash and sending it to a landfill.
