Dear Reader ,
Here is your customized PHYSorg.com Newsletter for week 41:
Scientists suggest that cancer is purely man-made
(PhysOrg.com) -- Cancer is a modern, man-made disease caused by environmental factors such as pollution and diet, a study by University of Manchester scientists has strongly suggested.
Planet hunters no longer blinded by the light
(PhysOrg.com) -- University of Arizona astronomers have developed a way to see faint planets previously hidden in their star's glare. The new mode enables scientists to search for planets closer to the star than has been previously possible.
Cracks in the Universe: Physicists are searching for the fingerprints of cosmic strings
Physicists are hot on the trail of one of strangest theorized structures in the universe. A team of researchers have announced what they think are the first indirect observations of ancient cosmic strings, bizarre objects thought to have contributed to the arrangement of objects throughout the universe.
Carbon dioxide controls Earth's temperature
(PhysOrg.com) -- Water vapor and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.
Scientists propose 'hidden' 3D optical data storage technique
(PhysOrg.com) -- By using a laser to reversibly combine and separate molecules, scientists have demonstrated a new optical data storage technique. Because the data can be read by only one kind of imaging technique (second-harmonic generation-assisted imaging), the new method could be used for hidden 3D data storage.
Smaller, cheaper, 300 times more intense: Scientists prove theory which could revolutionise lasers
(PhysOrg.com) -- More brilliant X-rays, more cost-effective methods for developing new energy sources and advanced manufacturing processes are just some of the benefits which may come from a novel technology, proven at the theoretical level by a consortium of British and European laser scientists.
Paraplegics have been given new hope for walking (w/ Video)
(PhysOrg.com) -- Berkeley Bionics unveiled eLEGS exoskeleton at a press conference on October 7 in San Francisco. Berkeley Bionics' CEO, Eythor Bender stated that their mission is to provide people with unprecedented mobility options.
Physicists observe electron ejected from atom for first time
Physicists at the University of California, Berkeley in collaboration with researchers from the Max Planck Institute of Quantum Optics and the U.S. Department of Energy's Lawrence Berkeley National Laboratory, became the first researchers to observe the motion of an atom's valence or outermost electrons in real-time by investigating the ejection of an electron from an atom by an intense laser pulse.
Gravity up close: Looking for extra dimensions by measuring gravity at the microscopic level
Scientists know how gravity works at big distances -- the inter-planetary or inter-stellar range -- but does it work the same way at the inter-atomic range?
Mass limits of dark matter derived from 'strange' stars
(PhysOrg.com) -- Much of the matter in our universe may be made of a type of dark matter called weakly interacting massive particles, better known as WIMPs. Although some scientists predict that these hypothetical particles possess many of the necessary properties to account for dark matter, so far scientists have not been able to make any definite predictions of their mass. Now, in a new study, physicists have derived a limit on the WIMP mass by calculating how these dark matter particles can transform neutron stars into stars made of strange quark matter, or "strange" stars.
Private spaceship makes first solo glide flight (w/ Video)
Virgin Galactic's space tourism rocket SpaceShipTwo achieved its first solo glide flight Sunday, marking another step in the company's eventual plans to fly paying passengers.
Scientists say the Big One could be even bigger
The Big One predicted for the San Andreas fault could end up being bigger than earthquake experts previously thought.
Mysterious pulsar with hidden powers discovered
Dramatic flares and bursts of energy - activity previously thought reserved for only the strongest magnetized pulsars - has been observed emanating from a weakly magnetised, slowly rotating pulsar. The international team of astrophysicists who made the discovery believe that the source of the pulsar's power may be hidden deep within its surface.
Triple-mode transistors show potential: Researchers introduce graphene-based amplifiers
(PhysOrg.com) -- Rice University research that capitalizes on the wide-ranging capabilities of graphene could lead to circuit applications that are far more compact and versatile than what is now feasible with silicon-based technologies.
Cause of the big plague epidemic of Middle Ages identified
(PhysOrg.com) -- The 'Black Death' was caused by at least two previously unknown types of Yersinia pestis bacteria.
Friction research casts doubt on fundamental physics law
(PhysOrg.com) -- New research on frictional slipping has revealed that some of the basic assumptions of introductory physics do not hold at small scales. The findings may be useful in the study of earthquakes.
Ghosts of the future: First giant structures of the universe
(PhysOrg.com) -- Astronomers using the South Pole Telescope report that they have discovered the most massive galaxy cluster yet seen at a distance of 7 billion light-years. The cluster (designated SPT-CL J0546-5345) weighs in at around 800 trillion Suns, and holds hundreds of galaxies.
Introducing Japan's new singing robot (w/ Video)
(PhysOrg.com) -- A new humanoid robot, the HRP-4, has been unveiled at the CEATEC Japan 2010 trade show. The robot, nicknammed "diva-bot," has learned to sing by mimicking a human singer, enabling it to sound natural and to sing with more expression than any previous robot.
Study confirms: Whatever doesn't kill us can make us stronger
We've all heard the adage that whatever doesn't kill us makes us stronger, but until now the preponderance of scientific evidence has offered little support for it.
The spice of life: Curry's main ingredient has more to offer than good flavor
Mahtab Jafari's research shows curry's main ingredient has more to offer than good flavor. It extended the lifespan of fruit flies by up to 20 percent, while improving locomotion and having tumor-prevention properties.
