Congress should minimally modify – and not, as petroleum-related interests have increasingly lobbied for, repeal – the Renewable Fuel Standard, the most comprehensive renewable energy policy in the U.S., according to a new paper from two University of Illinois researchers.
Scientists studying the behavior of platinum particles immersed in hydrogen peroxide may have discovered a new way to propel microscopic machines. The new mechanism is described in The Journal of Chemical Physics, which is produced by AIP Publishing.
ESA’s comet-chasing mission Rosetta will wake up in 100 days’ time from deep-space hibernation to reach the destination it has been cruising towards for a decade. Comets are the primitive building blocks of the Solar System and the likely source of much of Earth’s water, perhaps even delivering to Earth the ingredients that helped life evolve.
I love art that plays tricks on my eyes, making me see something that isn’t there but is. The upcycled ‘Rising Moon’installation created for last month’s Mid-Autumn Festival in Hong Kong is just such a piece of art.
There’s no denying it: most of us depend on electronics in every aspect of our lives. Even if you don’t own that many gadgets, electronics fill the hospitals, police departments, schools, and farms that we count on for valuable services. When these vital electronics die or break, they become part of the 50 million tons of e-waste generated every year.
43 year old Chinese entrepreneur, Wang Fuming, has 6 cockroach farms with 10 million cockroaches. Stay with me, people, don't squirm away. Since 2010 the price of dried cockroaches has increased 10-fold. Mr. Fuming will make you feel pathetic for complaining to your local slumlord.
When a natural disaster strikes and too many people take to their mobile phones at once, cellular networks easily overload. But a University of British Columbia graduate student has developed a solution to ensure that calls don’t get dropped and texts make it to their destination.
Heart-breaking accounts of cyber bullying and suicide seem all too common, but a new study offers hope that social media can become an early warning system to help prevent such tragedies.
The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to understand.
Vast areas on the Northern Hemisphere are covered by tundra. Here, dwarf shrubs, sedges, mosses etc. thrive on top of permafrost in areas where only the uppermost soil layer thaws during the short Arctic summer.
Ripped apart by tectonic forces, Hebes Chasma and its neighbouring network of canyons bear the scars of the Red Planet’s early history. ESA’s Mars Express has flown over this region of Mars on numerous occasions, but this new eight-image mosaic reveals Hebes Chasma in full and in greater detail than ever (click image for full mosaic).
How much do you know about glass, other than that it’s a pain to clean up when it breaks? Glass is made from a combination of sand, flint, or other silica, thrown together with some fixed alkalies, and in some cases a metallic oxide. Glass is a marvelous substance. It’s the only material that can be recycled indefinitely without losing quality (unlike plastic).
The world of patents is a bit screwy these days, with trolls warping a system that was designed to encourage innovation by protecting and rewarding innovators. Still, it has to be seen as an encouraging sign for renewable energy that the number of patents issued in the broad field has skyrocketed of late.
It wasn't amber that housed them, but shale, nevertheless scientists have a first: an intact blood meal found in a fossil. Yeah, it sounds real Jurassic Park but no one is putting up raptor fences quite yet. Nope. The DNA in the blood is most likely degraded. Score one to reality.
One of the most controversial issues emerging from the recent Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) is the failure of global climate models to predict a hiatus in warming of global surface temperatures since 1998.
Most microbial researchers grow their cells in petri-dishes to study how they respond to stress and damaging conditions. But, with the support of funding from NASA, researchers in LSU’s Department of Biological Sciences tried something almost unheard of: studying microbial survival in ice to understand how microorganisms could survive in ancient permafrost, or perhaps even buried in ice on Mars.
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 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.
Chemists at Boston College have achieved a series of breakthroughs in their efforts to develop an economical means of harnessing artificial photosynthesis by narrowing the voltage gap between the two crucial processes of oxidation and reduction, according to their latest research, published this week in the journal Angewandte Chemie.
Did you know that some research shows just looking at trees improves our health? It’s also been found that just spending time in a natural environment, i.e. in the presence of plants, trees, and animals, can reduce blood pressure and extend our lifespan.
