Lithium-polysulfide battery helps solar and wind power the grid

Researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have managed to design a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.

This galaxy turns gas into stars

Astronomers have discovered a galaxy transforming gas into stars with almost 100 percent efficiency - a rare phase of galaxy evolution that is the most extreme yet observed.

Report: Global cooling ended in the 19th century

The most comprehensive evaluation of temperature change on Earth’s continents over the past 1,000 to 2,000 years indicates that a long-term cooling trend - caused by factors including fluctuations in the amount and distribution of heat from the sun, and increases in volcanic activity - ended late in the 19th century.

Winflo is a green floating turbine design

Add Winflo to the growing number of floating turbine designs that looks like it might make it onto the water in the next few years.

Generating electricity from the sea

Waves may not be that predictable, even though technology and forecasting has improved (from World War II, when wave forecasting began in earnest, thanks to the requirements of the D-Day landing, up through the sophisticated models used by sports organizations like Surfline today), but the tides are thoroughly predictable.

Hubble offers a closer look at Comet ISON

NASA's Hubble Space Telescope has offered astronomers their clearest view yet of Comet ISON, a newly-discovered sun grazer comet that may light up the sky later this year, or come so close to the Sun that it disintegrates.

Video: This algorithm simulates evolution

A research team led by Cornell University's Creative Machines Lab has created a computer algorithm that simulates virtual creatures evolving their squishy, muscle-like features in order to teach themselves to walk.

Jupiter's water linked to comet impact

The European Space Agency's (ESA) Herschel space observatory has solved a long-standing mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994.

Edison2 VLC 4.0 hybrid wants to redefine the auto industry

In 2010, Lynchburg-based Edison2 won the Progressive Insurance Automotive X Prize with its Very Light Car (VLC) concept.

Hubble spots a hidden globular cluster

Palomar 2 is part of a group of 15 globulars known as the Palomar clusters. These clusters, as the name suggests, were discovered in survey plates from the first Palomar Observatory Sky Survey in the 1950s, a project that involved some of the most well-known astronomers of the day, including Edwin Hubble.

These apartments are powered by algae

In what may be one of the most potent recent symbols of the spirit of Earth Day in the green building movement, a new apartment complex in Hamburg, Germany, has op

The right-left solution for on-chip optics

A team of Harvard researchers has managed to create a type of nanoscale device capable of converting an optical signal into waves that travel along a metal surface.

Black holes measure the expansion of our universe

A few years ago, researchers revealed that the universe is expanding at a much faster rate than originally believed — a discovery that earned a Nobel Prize in 2011.

Claim: Earth hottest in 1,400 years

Fueled by industrial greenhouse gas emissions, Earth's climate warmed more between 1971 and 2000 than during any other three-decade interval in the last 1,400 years.

Warm water cools this cloud comptuing center

The advent and rapid proliferation of cloud computing has revolutionized the way we store, process and manage data, but it comes at an environmental cost that’s not always obvious.

Twin’Z is Renault's new EV

Renault, in planning what kind of future urban cars it might unveil in key markets, recently showcased the Twin’Z as its fifth iteration of its new design strategy.

A massive star factory in an early universe

The first galaxies were small, then eventually merged together to form the behemoths we see in the present universe.

This titanium skin eats air pollution

Titanium dioxide—the familiar white pigment in paint, toothpaste, skim milk, and sunblock—is promoted as a "smog-eating" coating or additive to roofs, facades, road concrete, roadside barriers, and other surfaces.

Porsche Panamera hybrid gets plugged-in

While electric cars continue to, well, electrify the media and even charge up EV sales among the public, hybrids continue their relentless march across all auto makes, including luxury brands.

NASA's Hubble space telescope snaps a horsehead of a different color

NASA's Hubble Space Telescope has photographed the iconic Horsehead Nebula in a new, infrared light to mark the 23rd anniversary of the famous observatory's launch aboard the space shuttle Discovery on April 24, 1990.
