A novel device that uses only sunlight and wastewater to produce hydrogen gas could provide a sustainable energy source while improving the efficiency of wastewater treatment.
A research team led by Yat Li, associate professor of chemistry at the University of California, Santa Cruz, developed the solar-microbial device and reported their results in a paper published in the American Chemical Society journal ACS Nano.
Brewing beer from barley grown on the space station and dunking meteorites in wine may sound like cheap gimmicks to boost sales, but there can often be some cool science (or at least valuable public outreach) benefits to meddling with space age alcoholic beverages. But can brewing beer with moon dust have any impact on taste? According to a Delaware-based brewery, of course it does! Plus, if you drink their “Celest-jewel-ale,” you’re guaranteed a thoroughly spaced-out experience.
Astronomers have found the shattered remains of an asteroid that contained huge amounts of water orbiting an exhausted star, or white dwarf. This suggests that the star GD 61 and its planetary system – located about 150 light years away and at the end of its life – had the potential to contain Earth-like exoplanets, they say.
A charred black pebble found in the Egyptian desert may be a piece of a comet that shattered near Earth about 28 million years ago. If so, the stone would offer a first close-up glimpse of rock that formed at the very edges of the solar system.
Current efforts to find exoplanets with the potential to harbor life habitable planets and exoplanets with life focus on smaller stars than the Sun, because these so called M dwarfs or red dwarfs make up more than 75% of stars in the solar neighborhood. It may be possible to find habitable planets around these small stars with the current level of technology. Thus searching for habitable planets around M dwarfs is considered the fast track to find a second Earth. High levels of atmospheric oxygen are considered the most promising indicator for life on exoplanets.
A lonely planet floating through space without a companion star has been discovered by an international team of astronomers who said that it is the first planet to be found without a sun.
A smash-up that created Pluto’s largest moon, Charon, likely sprayed debris four billion years ago that formed the genesis of the other moons scientists are spotting today, a new study concludes.
DENVER—“The Origin of Titan—So Big … So Alone.” That was the playful title of a talk given here yesterday at the annual meeting of the Division for Planetary Sciences. The gist? Saturn’s relatively huge moon Titan, which orbits unaccompanied by the usual retinue of similar-sized moons, started out as three or four standard-issue satellites of the ringed planet that ran amok, collided, and merged into one huge moon and a few scraps of debris.
Diamonds may fall from the sky on the gas giants Jupiter and Saturn.
When astronomers were selling the idea of a NASA mission to Pluto, they added a sense of urgency. No, they didn’t want to scout out Pluto as an outpost for setting up an early warning system in case of an alien invasion; planetary scientists warned that if we don’t visit the far-flung planet soon, the Pluonian atmosphere will freeze out and collapse onto the surface as fresh nitrogen-methane snow.
The latest analysis of the bollide that burst over Chelyabinsk, Russia in February suggests that the risk from such airbursts — which occur when friction in our atmosphere heats up a meteor — may be greater than previously thought.
At the end of August, a group of 140 palaeontologists from around the world gathered in Edinburgh to discuss their research, ranging from dinosaur feeding behaviour to pterosaur flight and the world’s largest bony fish – the latter being the outcome of research supported by Glasgow University and National Museums Scotland.
Without predators like dingoes to control kangaroo populations, culling may be necessary to restore the natural balance and ensure the future of the Australian landscape, according to new University of Canberra research.
An online game will challenge computer users to solve an archaeological puzzle: how to put together thousands of stone fragments to reconstruct the chiseled design on a 1,200-year-old Scottish monument.
Humans love to hear about ancient history, but they aren't always that great at preserving it. Here are some of the worst, most thoughtless, and just plain dumbest ways that humans have wrecked their own heritage.
Women made most of the oldest-known cave art paintings, suggests a new analysis of ancient handprints. Most scholars had assumed these ancient artists were predominantly men, so the finding overturns decades of archaeological dogma.
More than 10 percent of high school seniors recently admitted to using synthetic marijuana, also known by nicknames like Spice, K2, fake weed and Moon Rocks. And among that age group, the drug is second in popularity only to the old-fashioned pot.
What if we could deactivate treatments after use to cut the rise of antibiotic resistance? Researchers hope they may be able to control the medicines we take to fight infection using light.
