Dear Reader ,
Here is your customized PHYSorg.com Newsletter for week 27:
The universe may have been born spinning, according to new findings on the symmetry of the cosmos
(PhysOrg.com) -- Physicists and astronomers have long believed that the universe has mirror symmetry, like a basketball. But recent findings from the University of Michigan suggest that the shape of the Big Bang might be more complicated than previously thought, and that the early universe spun on an axis.
Is living forever in the future?
(Medical Xpress) -- Is it possible that your child could live to see 150 years of age? What about your grandchild living to see their 1000th birthday? According to a British biomedical gerontologist and chief scientist of the Strategies for Engineered Negligible Senescence (SENS) Foundation Aubrey De Grey, that is a definite possibility.
Scientists drag light by slowing it to speed of sound
(PhysOrg.com) -- Scientists at the University of Glasgow have, for the first time, been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.
Pixel perfect: Cornell develops a lens-free, pinhead-size camera
(PhysOrg.com) -- It's like a Brownie camera for the digital age: The microscopic device fits on the head of a pin, contains no lenses or moving parts, costs pennies to make – and this Cornell-developed camera could revolutionize an array of science from surgery to robotics.
How hot did Earth get in the past? Scientists uncover new information
The question seems simple enough: What happens to the Earth's temperature when atmospheric carbon dioxide levels increase? The answer is elusive. However, clues are hidden in the fossil record. A new study by researchers from Syracuse and Yale universities provides a much clearer picture of the Earth's temperature approximately 50 million years ago when CO2 concentrations were higher than today. The results may shed light on what to expect in the future if CO2 levels keep rising.
Global warming pause linked to sulfur in China
Scientists have come up with a possible explanation for why the rise in Earth's temperature paused for a bit during the 2000s, one of the hottest decades on record.
New force driving Earth's tectonic plates discovered
Bringing fresh insight into long-standing debates about how powerful geological forces shape the planet, from earthquake ruptures to mountain formations, scientists at Scripps Institution of Oceanography at UC San Diego have identified a new mechanism driving Earth's massive tectonic plates.
World's first 'live' video feed of Earth from space
(PhysOrg.com) -- The world's first high definition streaming video camera to be installed on the International Space Station (ISS) has been announced by David Willetts, Minister for Universities and Science at the UK Space Conference on 4 July. The project is a joint venture between Canada, Russia and the UK.
Eye of Gaia: Billion-pixel camera to map Milky Way
The largest digital camera ever built for a space mission has been painstakingly mosaicked together from 106 separate electronic detectors. The resulting "billion-pixel array" will serve as the super-sensitive 'eye' of ESA's Galaxy-mapping Gaia mission.
US lawmakers vote to kill Hubble successor
In a fresh blow to NASA's post-shuttle aspirations, key US lawmakers voted Thursday to kill off funding for the successor to the vastly successful space-gazing Hubble telescope.
Mushroom lights up the night in Brazil: Researcher finds bioluminescent fungus not seen since 1840
In 1840, renowned English botanist George Gardner reported a strange sight from the streets of Vila de Natividade in Brazil: A group of boys playing with a glowing object that turned out to be a luminescent mushroom. They called it "flor-de-coco," and showed Gardner where it grew on decaying fronds at the base of a dwarf palm. Gardner sent the mushroom to the Kew Herbarium in England where it was described and named Agaricus gardneri in honor of its discoverer. The species was not seen again until 2009.
Double solar world record
(PhysOrg.com) -- A world record double by UNSW solar cell researchers promises to make solar power more affordable, with world-beating new technology delivering substantial efficiency gains at minimal extra cost.
Teaching the neurons to meditate
In the late 1990s, Jane Anderson was working as a landscape architect. That meant she didn't work much in the winter, and she struggled with seasonal affective disorder in the dreary Minnesota winter months. She decided to try meditation and noticed a change within a month. "My experience was a sense of calmness, of better ability to regulate my emotions," she says. Her experience inspired a new study which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, which finds changes in brain activity after only five weeks of meditation training.
Tempest-from-hell seen on Saturn
(PhysOrg.com) -- Scientists analyzing data from NASA's Cassini spacecraft now have the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth.
Herschel Space Observatory discovers source of cosmic dust in a stellar explosion
(PhysOrg.com) -- ESA's Herschel Space Observatory is helping unravel the mystery of where cosmic dust comes from. Thanks to the resolution and sensitivity of Herschel, astronomers have been able to detect cosmic dust from a supernovae, adding weight to the theory that these cosmic fireworks are responsible for its creation.
Study demonstrates how memory can be preserved -- and forgetting prevented
As any student who's had to study for multiple exams can tell you, trying to learn two different sets of facts one after another is challenging. As you study for the physics exam, almost inevitably some of the information for the history exam is forgotten. It's been widely believed that this interference between memories develops because the brain simply doesn't have the capacity necessary to process both memories in quick succession. But is this truly the case?
Nanoscientists build antenna for light
University of Toronto researchers have derived inspiration from the photosynthetic apparatus in plants to engineer a new generation of nanomaterials that control and direct the energy absorbed from light.
Panasonic releases a solar charger with USB, AA battery slots and LED lights
(PhysOrg.com) -- The idea of a solar charger is not a new one. There are a whole host of them for the mobile device, but a lot of them are too expensive to be purchased by the average consumer. Other charge devices too slowly. Only time will tell which solar charger becomes the pragmatic option.
MIT spinout unveils new more powerful direct-diode laser
(PhysOrg.com) -- TeraDiode, a spinout company from MIT and located nearby in Littleton, MA, has unveiled, a new powerful direct-diode laser capable of cutting all the way through steel up to half an inch thick at various speeds. The laser is based on technology developed by company co-founders Dr. Bien Chann and Dr. Robin Huang while still at MIT.
Just add water and treat brain cancer
Researchers at the Johns Hopkins University School of Medicine have developed a technique that delivers gene therapy into human brain cancer cells using nanoparticles that can be freeze-dried and stored for up to three months prior to use. The shelf-stable particles may obviate the need for virus-mediated gene therapy, which has been associated with safety concerns. The report appears in the August issue of Biomaterials.
