Ancient secrets which save your sex life

Man has two basic requirements – food and the sexual gratification. In order to enjoy a healthy lifestyle it is important to suffice these two requirements or else you can see chaos and disaster seen among the people. Food we all know and have been consuming since we were kids, however, this is not the case with sex. The desire to have sexual gratification comes when kids turn adolescent.

So, when it comes to sex life, there are different ways to enjoy it, however, if you look at the core, nothing really has changed since past centuries. Though the lifestyle has changed a lot and would continue changing, however, sex life seems to remain unchanged. You will find various ancients secrets, which can help you in having a good sex life. So how about checking some of the ancient secrets that can really save your sex life in the following paragraphs: (more…)

China has potential to be leader in global sustainability

China, with its enormous cities and vast countryside, is a potential star in the ongoing global drama of slashing carbon emissions.

In this week’s Nature, a Michigan State University researcher and an international team of sustainability experts propose a script.

China already is a star in unleashing carbon dioxide emissions. In 2011, it accounted for a quarter of the world’s total. The problems – air pollution, squandered energy resources and economic stresses that squelch growth – also come with tremendous opportunity for China to be leader in slashing emissions. Along the way, China’s vast variety of economic and geographic circumstances offers a chance to set examples for its global neighbors. (more…)

Forecast for Titan: Wild Weather Could be Ahead

Saturn’s moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan’s northern hemisphere, waves could ripple across the moon’s hydrocarbon seas, and hurricanes could begin to swirl over these areas, too. The model predicting waves tries to explain data from the moon obtained so far by NASA’s Cassini spacecraft. Both models help mission team members plan when and where to look for unusual atmospheric disturbances as Titan summer approaches.

“If you think being a weather forecaster on Earth is difficult, it can be even more challenging at Titan,” said Scott Edgington, Cassini’s deputy project scientist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “We know there are weather processes similar to Earth’s at work on this strange world, but differences arise due to the presence of unfamiliar liquids like methane. We can’t wait for Cassini to tell us whether our forecasts are right as it continues its tour through Titan spring into the start of northern summer.” (more…)

Long Predicted Atomic Collapse State Observed in Graphene

Berkeley Lab researchers recreate elusive phenomenon with artificial nuclei

The first experimental observation of a quantum mechanical phenomenon that was predicted nearly 70 years ago holds important implications for the future of graphene-based electronic devices. Working with microscopic artificial atomic nuclei fabricated on graphene, a collaboration of researchers led by scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have imaged the “atomic collapse” states theorized to occur around super-large atomic nuclei.

“Atomic collapse is one of the holy grails of graphene research, as well as a holy grail of atomic and nuclear physics,” says Michael Crommie, a physicist who holds joint appointments with Berkeley Lab’s Materials Sciences Division and UC Berkeley’s Physics Department. “While this work represents a very nice confirmation of basic relativistic quantum mechanics predictions made many decades ago, it is also highly relevant for future nanoscale devices where electrical charge is concentrated into very small areas.” (more…)

Beetroot juice – the winning formula for team sports

New research shows that drinking beetroot juice can significantly improve performance in team sports involving bouts of high intensity exercise.

Trials by the University of Exeter Sport and Health Sciences department have found a direct link between the high nitrate content of beetroot and the chemical processes needed to get muscles working at their most efficient during intermittent bursts of activity.

During the tests, sportsmen were either given beetroot juice with a full complement of nitrates, or juice which had had the nitrate removed. Those who had taken the nitrate-rich juice were found to have a distinct advantage when exercising over those who had been given the control juice to drink. (more…)

Engineering Bacterial Live Wires

Berkeley Lab scientists discover the balance that allows electricity to flow between cells and electronics

Just like electronics, living cells use electrons for energy and information transfer. Despite electrons being a common “language” of the living and electronic worlds, living cells cannot speak to our largely technological realm. Cell membranes are largely to blame for this inability to plug cells into our computers: they form a greasy barrier that tightly controls charge balance in a cell.  Thus, giving a cell the ability to communicate directly with an electrode would lead to enormous opportunities in the development of new energy conversion techniques, fuel production, biological reporters, or new forms of bioelectronic systems.

Vortex Loops Could Untie Knotty Physics Problems

University of Chicago physicists have succeeded in creating a vortex knot—a feat akin to tying a smoke ring into a knot. Linked and knotted vortex loops have existed in theory for more than a century, but creating them in the laboratory had previously eluded scientists.

Vortex knots should, in principle, be persistent, stable phenomena. “The unexpected thing is that they’re not,” said Dustin Kleckner, a postdoctoral scientist at UChicago’s James Franck Institute. “They seem to break up in a particular way. They stretch themselves, which is a weird behavior.” (more…)
