World's biggest antimatter nucleus produced at Brookhaven
Ars Technica
Members of the international STAR collaboration at the Relativistic Heavy Ion Collider have detected the antimatter partner of the helium nucleus: antihelium-4. This new particle, also known as the anti-alpha, is the heaviest antinucleus ever detected, topping a discovery announced by the same collaboration just last year. Laboratory production of anti-matter may help explain why our universe appears to be made entirely of ordinary matter when matter and antimatter are understood to have been created in equal amounts at the time of the Big Bang.More

Did the early universe have 1 dimension?
Space Daily
In 2010, Dejan Stojkovic and colleagues proposed that the early universe — which exploded from a single point and was very, very small at first — was one-dimensional (like a straight line) before expanding to include two dimensions (like a plane) and then three (like the world in which we live today). In a new paper in Physical Review Letters, Stojkovic and Jonas Mureika describe a test using gravitational wave astronomy that could prove or disprove the "vanishing dimensions" hypothesis.More

Is a nuclei-based laser possible?
Physical Review Focus
For years, physicists have wanted to make a nuclear laser — one that depends on the excitation of nuclei rather than of electrons. A proposal in the April 22 Physical Review Letters suggests a path to creating such a laser, relying on some quirks of the nuclear structure of thorium. More

Detecting exo-planets via their radio-emissions
National Geographic
Auroras, with their distinct radio emissions, have been observed at all planets in our solar system, which have a global magnetic field and a significant atmosphere. Astronomers are supposing that auroral radio-emissions from distant planets, faint as they may be, could be a detected by next generation radio-telescopes, like the LOFAR array currently being built in Europe.More

South African cabinet endorses fracking moratorium
South Africa 24
In a decision hailed as a victory for astronomy research, cabinet ministers in South Africa have imposed a moratorium on "fracking" in the region where the Southern Africa Large Telescope and the KAT-7 radio telescope are situated. Astronomers at the South Africa Astronomical Observatory and the SKA Africa Project Office had raised several concerns about the complex method that presents several challenges to the front-line astronomy research occurring in the region.More

Beetle bling: Researchers discover optical secrets of 'metallic' beetles
PhysOrg.com
Optical reflection experiments conducted by a team of researchers at the University of Costa Rica have found that the brilliant gold coloring of the beetle Chrysina aurigans and silver-colored beetle Chrysina limbata are created by the unique structural arrangements of dozens of separate layers of chitin—a nitrogen-containing complex sugar that creates the hard outer skeletons of insects, crabs, shrimps and lobsters. The study has given optics researchers new insights into the way biology can recreate the appearance of some of nature's most precious metals, which in turn may allow researchers to produce new materials based on the natural properties found in the beetles' coloring.More

Carbon nanotubes capture cancer cells
MedicalPhysicsWeb
Researchers in the U.S. have made a new device capable of detecting cancer cells and viruses. The device uses antibody-functionalized porous nanotubes assembled in a microfluidic device. The device could eventually be developed into low-cost tests for doctors to use in developing countries. More

Nigerian scientists produce chocolate with elevated melting point
PhysicsWorld
Nigeria produces most of the world's cocoa but consumes only small amounts of chocolate due to the materials thermal properties. Nigerian scientists have recently created a "thermo-resistant" chocolate that holds its form and still tastes just right by adding varying amounts of cornstarch and gelatin to chocolate ensured that the chocolate melted at about 40–50 C, instead of its normal melting point at about 25–33 C.

NASA celebrates Hubble's 21st birthday with stunning galaxy images
PC Magazine
NASA is celebrating the 21st birthday of the Hubble telescope, but rather than a round of shots, the space agency is celebrating the milestone by pointing Hubble's eye in the direction of interacting galaxies known as Arp 273. Arp 273 is in the constellation Andromeda and is about 300 million light years away from Earth. More

Should a midsized tokamak be an alternative to ITER?
American Institute of Physics
A physicist at Princeton Plasma Physics Laboratory is proposing a midsize tokamak as either a fast-tracked experiment in support of the International Thermonuclear Experimental Reactor or an alternative option to it. In the new journal AIP Advances, Ernesto Mazzucato, asserts that the multinational approval process of ITER presents a risky situation that could slow down the development of nuclear fusion as a viable source of energy. Mazzucato's alternative reactor would operate in a regime of low plasma recycling that existing experiments indicate can lead to improved energy confinement. More

Journal of Biomedical Optics pays tribute to Michael Feld
SPIE
MIT professor Michael Feld was a towering figure in physics and biomedical optics. He made the first experimental observations of superradiance, and developed the first single-atom laser. Feld had a gift for building collaborations across disciplines, working with clinicians, engineers, biologists and chemists. He was an early and persistent leader of efforts to make MIT a community that welcomed minorities. He helped persuade MIT to establish the Dr. Martin Luther King, Jr. Visiting Professor Program. He served as an advisor to NSBP members, Ronald McNair and Marta Dark. More
