Approximately 90% of world’s electricity is generated in turbines moved by hot steam, which, unfortunately, operate only at 30 to 40 percent efficiency. This means that around two thirds of the total energy input is lost into the environment as waste heat. Thermoelectric materials can convert such waste heat into useful electricity, although they are […]

Massive storms on Uranus baffle scientists Astronomers have detected a wave of powerful storms touching down on the planet Uranus, surprising scientists who previously observed much more placid weather. Some of the storms are so bright that even amateurs can observe them using less advanced equipment. National Geographic The puzzle over organic matter on Mars […]

The Ebola outbreak has brought the fear of a viral pandemic to the headlines once more, as it happened before with the avian or swine flu. Although viruses-caused infections catch most of attention on the media, the greatest risk to human health comes from other microorganisms, the antibiotic-resistant bacteria. Contrary to viral outbreaks, the threat […]

Half of all stars exist outside of galaxies As many as half the stars in the universe may be galaxy castoffs, causing a diffuse glow in the cosmos. Researchers sent a rocket beyond the atmosphere’s edge to record images in wavelengths of near-infrared light, leading them to the surprising discovery. Los Angeles Times / Science […]

Earth’s water may be more ancient than previously estimated Scientists have come across evidence suggesting that Earth’s water may have been around for much longer than previously thought. The latest findings show that water may have been present in the inner solar system at least 135 million years earlier than previous estimates and that it […]

3D map shows the adolescent universe Astronomers have pieced together an image of what the adolescent universe looked like using just four hours of telescope observation time, producing a three-dimensional map. The map, millions of light-years across, shows areas of high-density matter that appear to be galaxies as they were just 3 billion years after […]

Breaking waves provide some warmth to surf zones Breaking waves warm the water in the surf, and in some cases may provide more heat than sunshine. Scientists said that in areas like the Pacific Northwest, which have more powerful waves and cloudy skies, heating could be almost three times stronger that what the sun provides […]

Ancient Antikythera wreckage holds treasure trove of artifacts Researchers excavating the 2,000-year-old wreckage of the Antikythera in Greece have found a treasure trove ancient goods. “The evidence shows this is the largest ancient shipwreck ever discovered,” said marine archaeologist Brendan Foley. The wreckage was discovered more than a century ago but the current excavation has […]

Building machines which mimic the capacities of biological brains –and of the human brain in particular– is one of the main challenges of modern science. With the fast development of computer speed and power in the second half of the past century, this goal seemed, in the early days of artificial intelligence, simply a matter […]

Giant lava plain on moon likely due to tectonic stretching, not impact The massive plain of solidified lava on the moon, known as Oceanus Procellarum, wasn’t caused by an asteroid impact as previously thought, according to a study published in Nature. Instead, researchers say, the volcanic basalt was formed by tectonic stretching, according to data […]
