Scientists perceive plant function and how they optimize their renewal:

"Until now, it was not known how the order of events is guaranteed," Kirchhoff said. "Our results suggest that we have to understand the structural characteristics and dynamics of photosynthetic membranes to understand the repair of the energy-converting nanomachines. This has not been appreciated before."
Helmut Kirchhoff, an assistant professor in WSU's Institute of Biological Chemistry and corresponding author of the PNAS paper, said plants have had to deal with solar damage since the evolution of photosynthesis some 3.5 billion years ago. The process produces energy for the plant but also creates modified oxygen molecules, called reactive oxygen species, or ROS, that can damage proteins and other important plant molecules.
"ROS production can't be avoided, only minimized," said Kirchhoff. "It becomes a big problem for plants under unfavorable environmental conditions, like too much heat, too much light or insufficient nutrition." Read More:

The 9.7 Trillion Dollar Question | Cyclones and Climate Change |

Humanity and cyclones are no strangers to each other. Roughly 35 percent of the world’s 7 billion people are in the path of cyclones and coastal populations are expected to swell in the coming century. To understand the future damage that cyclones could inflict on ever-growing coastal cities, two researchers looked at 60 years of cyclone and economic data in a recent National Bureau of Economic Research study.  You can do a lot with $9.7 trillion: buy all the real estate in Manhattan 12 times over, purchase 22 carbon copies of Apple, or an absurd quantity of apples.

Tesla Motors is making its patents free and open source, in an effort to advance new electric car technologies |

In 2003, Musk co-founded Tesla Motors, which went public in 2010. Earlier this year, Musk announced that Tesla Motors is making its patents free and open source, in an effort to advance new electric car technologies.
Billionaire entrepreneur Elon Musk's electric car company will now offer all-wheel-drive versions of the Tesla Model S, including one high-end option that can accelerate from 0 to 60 mph in a little more than 3 seconds, USA Today reported. That speed puts Tesla's Model S among some of the fastest sedans.
Tesla will also introduce new autonomous safety features, including technology that can help the car park itself, and a feature that can nudge the vehicle over a lane when the driver hits the turn signal. The car will also be equipped with sensors that can read speed-limit signs and make appropriate adjustments, USA Today reported.    Read More:

Experiment with speeding ions verifies relativistic time dilation to new level of precision |

When Einstein came up with his theories on special relativity, the world was introduced to the idea of measuring time dilation—where an astronaut would age at a different rate than those left behind on Earth—due to the speed of light being a constant. Relativistic time dilation comes from the Lorentz invariance, which says that no matter where in the universe an object is, or at what speed it might be traveling, the rules remain the same. Since Einstein's time, scientists have conducted many experiments to prove the theory true—some by using natural objects such as the movement of the Earth in relation to other celestial bodies—others by conducting experiments in the lab. Such experiments have proven successful and today,

A solar cell that stores its own power: World’s first ‘solar battery’ runs on light and air |

Actually, the patent-pending device invented at The Ohio State University is both: the world’s first solar battery.

In the October 3, 2014 issue of the journal Nature Communications, the researchers report that they’ve succeeded in combining a battery and a solar cell into one hybrid device. Read More:

After-school exercise program enhances cognition in 7-, 8- and 9-year-olds |

Summary:
A nine-month-long, randomized controlled trial involving 221 prepubescent children found that those who engaged in moderate-to-vigorous physical activity for at least 60 minutes a day after school saw substantial improvements in their ability to pay attention, avoid distraction and switch between cognitive tasks, researchers report.
