Dear Reader ,
Here is your customized Phys.org Newsletter for week 13:
A new object at the edge of our Solar System discovered
The Solar System has a new most-distant member, bringing its outer frontier into focus.
Cosmologists cast doubt on inflation evidence
It was just a week ago that the news blew through the scientific world like a storm: researchers from the BICEP2 project at the South Pole Telescope had detected unambiguous evidence of primordial gravitational waves in the cosmic microwave background, the residual rippling of space and time created by the sudden inflation of the Universe less than a billionth of a billionth of a second after the Big Bang. With whispers of Nobel nominations quickly rising in the science news wings, the team's findings were hailed as the best direct evidence yet of cosmic inflation, possibly even supporting the existence of a multitude of other universes besides our own.
Plugging the hole in Hawking's black hole theory
(Phys.org) �Recently physicists have been poking holes again in Stephen Hawking's black hole theory � including Hawking himself. For decades physicists across the globe have been trying to figure out the mysteries of black holes � those fascinating monstrous entities that have such intense gravitational pull that nothing � not even light � can escape from them. Now Professor Chris Adami, Michigan State University, has jumped into the fray.
Crows complete basic 'Aesop's fable' task (w/ video)
New Caledonian crows may understand how to displace water to receive a reward, with the causal understanding level of a 5-7 year-old child, according to results published March 26, 2014, in the open access journal PLOS ONE by Sarah Jelbert from University of Auckland and colleagues.
Cleaner than electric? Mazda talks up gasoline engine fuel economy ambitions for SkyActiv 2
(Phys.org) �Auto-focused sites are buzzing over a recent report in Autocar, reporting Japanese automobile manufacturer Mazda's future gasoline engine technology, which will reduce carbon dioxide emissions below the amount generated to power electric cars.
Experiment opens the door to multi-party quantum communication (Update)
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, scientists have demonstrated full quantum nonlocality with more than two entangled photons.
Titan Project explores the smallest building blocks of matter
(Phys.org) �Our world is made up of particles so tiny they may actually be points in space. These are quarks, relative newcomers to the physics conversation that were not even postulated until the mid-1960s. Put them together and you get protons and neutrons. Put those together and you get the nuclei of atoms. Put those together and you get you and your universe.
Can light orbit a black hole?
Since black holes are the most powerful gravitational spots in the entire Universe, can they distort light so much that it actually goes into orbit? And what would it look like if you could survive and follow light in this trip around a black hole?
Dark energy hides behind phantom fields
Quintessence and phantom fields, two hypotheses formulated using data from satellites, such as Planck and WMAP, are among the many theories that try to explain the nature of dark energy. Now researchers from Barcelona and Athens suggest that both possibilities are only a mirage in the observations and it is the quantum vacuum which could be behind this energy that moves our universe.
Scientists solve riddle of celestial archaeology
A decades old space mystery has been solved by an international team of astronomers led by Professor Martin Barstow of the University of Leicester and President-elect of the Royal Astronomical Society.
Goats are far more clever than previously thought
Goats learn how to solve complicated tasks quickly and can recall how to perform them for at least 10 months, which might explain their remarkable ability to adapt to harsh environments, say researchers at Queen Mary University of London.
Ultra tiny camera has no lens � uses algorithm to develop pictures
(Phys.org) �An extremely tiny lensless camera, developed by Rambus, has been slowly making waves over the past year. Researchers for the company, David Stork and Patrick Gill won a Best Paper award at last year's Sencomm 2013 for describing what the company has created. They spoke again at last month's Mobile World Congress, describing their new type of camera�one that might someday soon be used to give virtually any digital device, some degree of vision.
Rainbow-catching waveguide could revolutionize energy technologies
(Phys.org) �By slowing and absorbing certain wavelengths of light, engineers open new possibilities in solar power, thermal energy recycling and stealth technology.
Hunt for an 'unidentified electron object'
New research sheds light on the nature of 'unidentified electron objects'�a mysterious class of objects that exists in superfluid helium at low temperature.
Researchers suggest changes to theories regarding neutron star crust structure
(Phys.org) �A pair of researchers affiliated with universities in Sweden and Denmark has published a paper in the journal Physical Review Letters, suggesting that current theories that describe the makeup of the crust of neutron stars need to be rethought. In their study Dmitry Kobyakov and Chris Pethick have found that if the crusts of neutron stars conformed to current thinking, they would be unstable.
Parallel programming may not be so daunting
Computer chips have stopped getting faster: The regular performance improvements we've come to expect are now the result of chipmakers' adding more cores, or processing units, to their chips, rather than increasing their clock speed.
Detecting gravitational waves at your desk
Physics is on the front pages of newspapers around the world. This time it is because of the announcement made by a team of scientists who seem to have found indirect evidence for the existence of "primordial gravitational waves".
Scientists discover material that can be solar cell by day, light panel by night
In the future, when your mobile or tablet runs out of battery, you could just recharge it by putting it out in the sun. Nanyang Technological University (NTU) scientists have developed a next-generation solar cell material which can also emit light, in addition to converting light to electricity.
Einstein's 'spooky' theory may lead to ultra-secure internet
(Phys.org) �Einstein's scepticism about quantum mechanics may lead to an ultra-secure internet, suggests a new paper by researchers from Swinburne University of Technology and Peking University.
New study shows major increase in West Antarctic glacial loss
Six massive glaciers in West Antarctica are moving faster than they did 40 years ago, causing more ice to discharge into the ocean and global sea level to rise, according to new research.
