Cannot wait for this material so that I can finally enjoy my run in the park near my US home in August.

WASHINGTON — Engineers have created clothing for a warming world — a fabric that allows your body heat to escape far better than other materials do.

It hasn’t been worn or tested by humans, so outside experts caution this is far from a sure thing, but a team at Stanford University engineered a fabric using nano technology that not only allows moisture to leave the body better, but helps infrared radiation escape better. As a result, they say in Thursday’s journal Science, the body should feel around 4.8 degrees (2.7 degrees Celsius) cooler than cotton and 3.8 degrees (2.1 degrees Celsius) chillier than commercially available synthetics.

UC San Diego researchers working with DARPA show how to make a low-power, lightweight system that can take advantage of unused frequencies and avoid interference.

Physicists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) are building a “star in a jar” — a miniature version of the how our Sun creates energy through fusion. It could provide humankind with near limitless energy, ending dependence on fossil fuels for generating electricity — without contributing greenhouse gases that warm the Earth, and with no long-term radioactive waste.

But that requires a “jar” that can contain superhot plasma — and is low-cost enough to be built around the world. A model for such a “jar,” or fusion device, already exists in experimental form: the tokamak, or fusion reactor. Invented in the 1950s by Soviet physicists, it’s a device that uses a powerful magnetic field to confine plasma (superhot charged gas) in the shape of a torus.

U.S. Dept. of Energy announces major new initiative toward clean, safe and virtually limitless power.

Researchers developed a method of transferring an energy source to virtually any shape using direct laser writing…

As electronics shrink in size, their energy sources have to fit into tighter, and sometimes more oddly-shaped, spaces. Researchers at the University of Missouri had this challenge in mind when they developed a method of transferring an energy source to virtually any shape using direct laser writing (DLW).

China has always been a frontrunner, especially in technological advancements. The country has engaged itself in increasingly audacious and ambitious projects. It is, therefore, no astonishment in calling China, ‘the rising power’.China has established Weather Modification Offices, that enables in manipulating weather using technology. The offices are a network of dedicated units that help in changing the weather throughout China. 55 billion tons of rain is created by China every year, making the country the largest cloud seeder on earth.

China has found the urge to manipulate weather mainly because of the extreme climate it experiences. The region has heavy downpour in rainy season while it suffers from drought in summers. Dust and sand storms are common in springtime. Moreover, given the fact that China has the largest population, it cannot afford to rely on climate. Most importantly, for agriculture. China found the only hope in technology in the manipulating weather for accruing benefits.

Weather modification offices require huge financial resources, human capital and weaponry. It is no wonder that China has spent millions of money on weather modification process. It has spent $150 million on single regional artificial rain program. China has escaped $10.4 billion dollars economic losses by employing weather modification system from 2002 to 2012. Over 35000 people have been employed to carry out this project. About 12000 rocket launchers are being used to fire pellets containing silver iodide into the clouds.

A future of soft robots that wash your dishes or smart T-shirts that power your cell phone may depend on the development of stretchy power sources. But traditional batteries are thick and rigid—not ideal properties for materials that would be used in tiny malleable devices. In a step toward wearable electronics, a team of researchers has produced a stretchy micro-supercapacitor using ribbons of graphene.

The researchers will present their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS).

“Most power sources, such as phone batteries, are not stretchable. They are very rigid,” says Xiaodong Chen, Ph.D. “My team has made stretchable electrodes, and we have integrated them into a supercapacitor, which is an energy storage device that powers electronic gadgets.”

Additional insights on methods in improving efficiencies during the conversion of light energy into chemical energy.

The chromatophore of purple bacteria is an intracellular spherical vesicle that exists in numerous copies in the cell and that efficiently converts sunlight into ATP synthesis, operating typically under low light conditions. Building on an atomic-level structural model of a low-light-adapted chromatophore vesicle from Rhodobacter sphaeroides, we investigate the cooperation between more than a hundred protein complexes in the vesicle. The steady-state ATP production rate as a function of incident light intensity is determined after identifying quinol turnover at the cytochrome bc1 complex (cytb⁢c1) as rate limiting and assuming that the quinone/quinol pool of about 900 molecules acts in a quasi-stationary state.
