Russians revive Ice Age flower from frozen burrow
It was an Ice Age squirrel's treasure chamber, a burrow containing fruit and seeds that had been stuck in the Siberian permafrost for over 30,000 years. From the fruit tissues, a team of Russian scientists managed to resurrect an entire plant in a pioneering experiment that paves the way for the revival of other species.
Rare whale caught on film for first time
Australian researchers Thursday revealed they had filmed a pod of extremely rare Shepherd's beaked whales for the first time ever.
Faster than light neutrinos? More like faulty wiring
You can shelf your designs for a warp drive engine (for now) and put the DeLorean back in the garage; it turns out neutrinos may not have broken any cosmic speed limits after all.
Time crystals could behave almost like perpetual motion machines
(PhysOrg.com) -- As every young science student knows, moving objects have kinetic energy. But just how much energy does something need to move? In a new study, a pair of physicists has shown that it’s theoretically possible for a system in its lowest energy state, or ground state, to exhibit periodic motion. This periodically moving system can be thought of as the temporal equivalent of a crystal, which is defined by its spatial periodicity. What’s even more intriguing about these "time crystals" is that, by exhibiting motion at their state of lowest energy, they break a fundamental symmetry called time translation symmetry and become "perilously close" to looking like perpetual motion machines.
World's best measurement of W boson mass tests Standard Model, Higgs boson limits
(PhysOrg.com) -- Just as firemen use different methods to narrow the location of a person trapped in a building, scientists employ two techniques to find the hiding place of the theorized Higgs particle: direct searches for Higgs interactions and precision measurements of other particles and forces.
Researchers build first physical 'metatronic' circuit
(PhysOrg.com) -- The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges using increasingly small and complicated circuits. And while those electrical advances continue to race ahead, researchers at the University of Pennsylvania are pushing circuitry forward in a different way, by replacing electricity with light.
Stark warning emerges from science summit
A stark theme emerged from an annual scientific get-together in Vancouver: the world must be helped to believe in science again or it could be too late to save our planet.
In distance space, a water world: Hubble reveals a new class of extrasolar planet
(PhysOrg.com) -- An international team of astronomers led by Zachory Berta of the Harvard-Smithsonian Center for Astrophysics (CfA) made the observations of the planet GJ 1214b.
Researchers say galaxy may swarm with 'nomad planets'
(PhysOrg.com) -- Our galaxy may be awash in homeless planets, wandering through space instead of orbiting a star.
HTML5 spec editor slams Google & gang's DRM bid
(PhysOrg.com) -- A draft proposal by Google, Microsoft and Netflix to introduce mechanisms for copy protection on web videos has generated strong opposition and a response that the proposal is "unethical." Reaction has been strong against the powerful trio's bid to see HTML5 carry digital rights management (DRM) tools.
Superbugs from space offer new source of power
Bacteria normally found 30km above the earth have been identified as highly efficient generators of electricity.
Researchers find classical musical compositions adhere to power law
(PhysOrg.com) -- A team of researchers, led by Daniel Levitin of McGill University, has found after analyzing over two thousand pieces of classical music that span four hundred years of history, that virtually all of them follow a one-over-f (1/f) power distribution equation. He and his team have published the results of their work in the Proceedings of the National Academy of Sciences.
Stars containing dark matter should look different from other stars
(PhysOrg.com) -- Finding evidence for dark matter – the unknown substance that theoretically makes up 23% of the universe – has been one of the biggest challenges in modern cosmology. Several experiments are underway to detect dark matter candidates known as Weakly Interacting Massive Particles (WIMPs) as they travel through the Earth. And experiments at the Large Hadron Collider (LHC) are trying to produce WIMPs through proton beam collisions. Now in a new study, scientists have shown that feebly annihilating dark matter particles captured inside a star can provide an additional source of energy to the star, resulting in changes to its structure and appearance. Observing these stars could potentially offer scientists a tool to detect and analyze this kind of dark matter.
The high price of losing manufacturing jobs: research
The loss of U.S. manufacturing jobs is a topic that can provoke heated arguments about globalization. But what do the cold, hard numbers reveal? How has the rise in foreign manufacturing competition actually affected the U.S. economy and its workers?
Motorized roller could mass-produce graphene-based devices
(PhysOrg.com) -- Finding a simple, scalable way to pattern graphene for future electronics applications is one of the biggest challenges facing graphene researchers. While lithography has been widely used to create graphene patterns for electronic devices, its multiple processing steps make it too complex for large-scale use. In a recent study, scientists have found that a motorized, movable roller can deposit a polymer solution onto a graphene surface in periodically striped and cross-striped patterns, which they used to make a transistor. By eliminating several steps involved in lithography, the new technique could lead to a low-cost method for producing graphene patterns for a variety of electronic devices on a large scale.
Mechanism behind capacitor's high-speed energy storage discovered
Researchers at North Carolina State University have discovered the means by which a polymer known as PVDF enables capacitors to store and release large amounts of energy quickly. Their findings could lead to much more powerful and efficient electric cars.
Spitzer finds solid buckyballs in space
(PhysOrg.com) -- Astronomers using data from NASA's Spitzer Space Telescope have, for the first time, discovered buckyballs in a solid form in space. Prior to this discovery, the microscopic carbon spheres had been found only in gas form in the cosmos.
First test-tube hamburger ready this fall: researchers
The world's first "test-tube" meat, a hamburger made from a cow's stem cells, will be produced this fall, Dutch scientist Mark Post told a major science conference on Sunday.
Oxford Nanopore announces groundbreaking GridION and MinION gene sequencers
(PhysOrg.com) -- Oxford University spinoff company, Oxford Nonopore has announced at this year’s Advances in Genome Biology and Technology conference in Florida, two new machines for sequencing genes. Of particular note is the MinION, a machine small enough to fit in the hand which can be plugged into a laptop’s USB port. The other, the GridION, is a larger version that can be stacked to increase processing power. Both rely on a technology known as strand sequencing whereby a nanopore (engineered protein) is used to pull strands of DNA through a hole where a microchip measures minute changes in the electrical current in the membrane around it as individual bases, or pairs are pulled through. Because of the way it is done, much longer sections of DNA can be examined at once, doing away with the need to examine small sections independently and then knitting the results together with a computer afterwards.
Researchers discover what cancer cells need to travel
(PhysOrg.com) -- Cancer cells must prepare for travel before invading new tissues, but new Cornell research has found a possible way to stop these cells from ever hitting the road.
