Dear Reader ,
Here is your customized PHYSorg.com Newsletter for week 20:
Planets that have no stars: New class of planets discovered
(PhysOrg.com) -- University of Notre Dame astronomer David Bennett is co-author of a new paper describing the discovery of a new class of planets -- dark, isolated Jupiter-mass bodies floating alone in space, far from any host star. Bennett and the team of astronomers involved in the discovery believe that the planets were most likely ejected from developing planetary systems.
Radio telescopes capture best-ever snapshot of black hole jets (w/ video)
(PhysOrg.com) -- An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy.
Heaven is a 'fairy story', says Stephen Hawking
British scientist Stephen Hawking has branded heaven a "fairy story" for people afraid of the dark, in his latest dismissal of the concepts underpinning the world's religions.
Nuclear magnetic resonance with no magnets
Nuclear magnetic resonance (NMR) is a powerful tool for chemical analysis and, in the form of magnetic resonance imaging (MRI), an indispensable technique for medical diagnosis. But its uses have been limited by the need for strong magnetic fields and big, expensive, superconducting magnets. Now Berkeley Lab scientists and their colleagues have demonstrated that they can do NMR in a zero magnetic field without using any magnets at all.
The next computer: your genes
(PhysOrg.com) -- "Human beings are more or less like a computer," Jian-Jun Shu tells PhysOrg.com. "We do computing work, and our DNA can be used in computing operations." Shu is a professor at the School of Mechanical and Aerospace Engineering at the Nanyang Technical University in Singapore. "For some problems, DNA-based computing could replace silicon-based computing, offering many advantages."
Dark Energy is real: WiggleZ galaxy project proves Einstein was right again
(PhysOrg.com) -- An Australian-based astronomy team, co-led by Professor Michael Drinkwater from the School of Mathematics and Physics (SMP) at The University of Queensland (UQ), has shown that the mysterious 'dark energy' is indeed real and not a mistake in Einstein's theory of gravity.
Spectacular mammal rediscovered after 113 years -- first ever photographs taken
(PhysOrg.com) -- A unique and mysterious guinea-pig-sized rodent, not seen since 1898 despite several organized searches, bizarrely showed up at the front door of an ecolodge at a nature reserve in Colombia, South America. The magnificent red-crested tree rat (Santamartamys rufodorsalis), stayed for almost two hours while two research volunteers took the first photos ever of a creature the world thought would never be seen again.
That anxiety may be in your gut, not in your head
For the first time, researchers at McMaster University have conclusive evidence that bacteria residing in the gut influence brain chemistry and behaviour.
Splitting water to create renewable energy simpler than first thought?
(PhysOrg.com) -- An international team, of scientists, led by a team at Monash University has found the key to the hydrogen economy could come from a very simple mineral, commonly seen as a black stain on rocks.
New solar product captures up to 95 percent of light energy
Efficiency is a problem with today's solar panels; they only collect about 20 percent of available light. Now, a University of Missouri engineer has developed a flexible solar sheet that captures more than 90 percent of available light, and he plans to make prototypes available to consumers within the next five years.
Seeing the planets for the trees
A recent study says that a particular mathematical technique could be used to detect forests on extrasolar planets.
'Time' not necessarily deeply rooted in our brains
(Medical Xpress) -- Hidden away in the Amazonian rainforest a small tribe have successfully managed what so many dream of being able to do – to ignore the pressures of time so successfully that they don’t even have a word for it.
Scientists looking to burst the superconductivity bubble
(PhysOrg.com) -- Bubbles are blocking the current path of one of the most promising high temperature superconducting materials, new research suggests.
Japanese electric car 'goes 300km' on single charge
Japanese developers have unveiled an electric car they said Wednesday can travel more than 300 kilometres before its battery runs flat.
Simplifying the process of detecting genuine multiparticle entanglement
(PhysOrg.com) -- The ability to entangle particles is considered essential for a number of experiments and applications. While we have seen evidence for quantum entanglement, it is still difficult to detect unambiguously. Multiparticle quantum correlations are especially important for work with optical lattices, superconducting qubits and quantum information processing. "Entanglement in large qubit systems is becoming more important," Bastian Jungnitsch tells PhysOrg.com. "Unfortunately, the characterization of multiparticle entanglement is difficult."
Humans 'predisposed' to believe in gods and the afterlife
A three-year international research project, directed by two academics at the University of Oxford, finds that humans have natural tendencies to believe in gods and an afterlife.
New omni-directional wind turbine can capture wind energy on building rooftops
(PhysOrg.com) -- Katru Eco-Energy, headed by founder and inventor, Varan Sureshan, has developed a new kind of wind turbine meant to capture the winds that fly in all directions atop big buildings, and unlike conventional devices, the IMPLUX, as it’s called, can capture wind from any direction as it stands; meaning without having to be repositioned or pointed. The IMPLUX achieves this feat by means of horizontal turbine blades that sit atop a vertical axis and are turned by wind that is pushed up through what Sureshan calls a "fluid dynamic gate."
Eurocopter X3: The world's fastest copter
(PhysOrg.com) -- If you asked a child how they would make a helicopter go faster, they would probably tell you to add another engine. The answer would be Zen simple and dead right. The engineers at Eurocopter also seem to have that same mentality and it worked.
Memristors: 'Computer synapse' analyzed at the nanoscale
(PhysOrg.com) -- Researchers at Hewlett Packard and the University of California, Santa Barbara, have analysed in unprecedented detail the physical and chemical properties of an electronic device that computer engineers hope will transform computing.
New blood test shows how long you will live
(Medical Xpress) -- A controversial test capable of revealing just how long you have to live is set to hit the market in Britain within the year. The test measures a person's telomeres which are the structures found on the tips of chromosomes and researchers believe that these telomeres are crucial indicators of the speed in which a body is ageing.
