Dear Reader ,
Here is your customized PHYSorg.com Newsletter for week 11:
Maglev track could launch spacecraft into orbit
(PhysOrg.com) -- With the aim to make it easier to launch spacecraft into low Earth orbit (LEO), two researchers have turned to maglev technology to catapult a payload hundreds of miles above the Earth. While the concept may sound far-fetched, the researchers argue that the potential benefits to humanity far outweigh the costs.
Researchers send 'wireless' message using neutrinos
(PhysOrg.com) -- A group of scientists led by researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, "Neutrino."
S.Korean, Russian scientists bid to clone mammoth
Russian and South Korean scientists have signed a deal on joint research intended to recreate a woolly mammoth, an animal which last walked the earth some 10,000 years ago.
3D-printer with nano-precision
Printing three dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices (see video). This opens up completely new areas of application, such as in medicine.
'Faster-than-light' particles fade after cross-check
Neutrinos do not go faster than light, according to fresh measurements of a test last year that had suggested the particles broke the Universe's speed limit, CERN said on Friday.
Mystery human fossils put spotlight on China
Fossils from two caves in south-west China have revealed a previously unknown Stone Age people and give a rare glimpse of a recent stage of human evolution with startling implications for the early peopling of Asia.
Scientists call for fundamental governance overhaul to ensure Earth's sustainability
A group of the world's leading environmental scholars are sounding the alarm that human societies need to transform their national and international environmental institutions into a more coherent and robust planetary stewardship model in order to steer away from rapid and irreversible changes to the Earth's subsystems.
Researchers develop graphene supercapacitor holding promise for portable electronics
(PhysOrg.com) -- Electrochemical capacitors (ECs), also known as supercapacitors or ultracapacitors, differ from regular capacitors that you would find in your TV or computer in that they store substantially higher amounts of charges. They have garnered attention as energy storage devices as they charge and discharge faster than batteries, yet they are still limited by low energy densities, only a fraction of the energy density of batteries. An EC that combines the power performance of capacitors with the high energy density of batteries would represent a significant advance in energy storage technology. This requires new electrodes that not only maintain high conductivity but also provide higher and more accessible surface area than conventional ECs that use activated carbon electrodes.
The annihilating effects of space travel
Long distance space travel could create the ultimate 'killer entrance', devastating your destination and anything around the arriving spacecraft, according to calculations by Professor Geraint Lewis and two honours students from the University of Sydney.
New compound discovered that rapidly kills liver cancer
Scientists have identified a new compound that rapidly kills hepatocellular carcinoma (HCC) cells, the most common form of liver cancer and fifth most common cancer worldwide, while sparing healthy tissue. The compound, Factor Qunolinone Inhibitor 1 (FQI1), works by inhibiting an oncogene originally discovered by a team of researchers led by Devanand Sarkar, M.B.B.S., Ph.D., Harrison Scholar at Virginia Commonwealth University (VCU) Massey Cancer Center, Blick Scholar and assistant professor in the Department of Human and Molecular Genetics and member of the VCU Institute of Molecular Medicine at the VCU School of Medicine.
Future NASA mission to sun 'a life's dream' for some
The chest-high rack of electronics Justin Kasper is assembling in a Massachusetts office park will fit in a shoe box before he's done.
Molecular graphene heralds new era of 'designer electrons'
Researchers from Stanford University and SLAC National Accelerator Laboratory have created the first-ever system of "designer electrons" – exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices.
Graphene battery demonstrated to power an LED
(PhysOrg.com) -- Scientists in Hong Kong have reported, in ArXiv, their experiments to make a graphene battery that they say generates an electrical current by drawing on the ambient thermal energy in the solution in which it is immersed.
Barrier to faster graphene devices identified and suppressed
These days graphene is the rock star of materials science, but it has an Achilles heel: It is exceptionally sensitive to its electrical environment.
Obama urges end to US reliance on foreign energy
US President Barack Obama called on Saturday for an end to America's dependence on foreign energy sources -- and to the multi-billion-dollar subsidies given each year to oil companies.
Third research team close to creating Majorana fermion
(PhysOrg.com) -- Recently there has been a virtual explosion of research efforts aimed at creating the elusive Majorana fermion with different groups claiming to be near to creating them. First there was news that a team at Stanford was on the precipice, then came reports that another group at Delft University of Technology in The Netherlands was very close as well. Now comes news of yet another team who some think may have the best chance yet of making them, and better yet, using them to help make quantum computing possible. This third group, made up of Chinese and American teams takes the approach, as they describe in their paper published in Science, of growing a topical insulator film on top of a superconductor.
Health insurance premiums will surpass median household income in 2033: study
(HealthDay) -- If current trends continue, health insurance premiums will surpass the median U.S. household income in 2033, a new study says.
Near-miss asteroid will return next year
(PhysOrg.com) -- When it whizzes past Earth in 2013, a newly discovered asteroid is going to miss our planet – but not by much. The 50 m space rock is expected to come closer than many satellites, highlighting the growing need to keep watch on hazards from above.
Laser lightning rod: Guiding bursts of electricity with a flash of light
Lightning is a fascinating but dangerous atmospheric phenomenon. New research reveals that brief bursts of intense laser light can redirect these high-power electrical discharges.
Study finds how to correct human mitochondrial mutations
Researchers at the UCLA stem cell center and the departments of chemistry and biochemistry and pathology and laboratory medicine have identified, for the first time, a generic way to correct mutations in human mitochondrial DNA by targeting corrective RNAs, a finding with implications for treating a host of mitochondrial diseases.
