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.
California wants fuel cell vehicles to be part of its ambitious plan to reduce greenhouse gas emissions in the state by 80 percent from 1990 levels by 2050. But right now, across the whole state, there are just nine publicly available hydrogen fueling stations. Clearly this is a problem.
Writing in Nature Communications, researchers at The University of Manchester led by Dr Aravind Vijayaraghavan, and Dr Michael Hirtz at the Karlsruhe Institute of Technology (KIT), have demonstrated that membranes can be directly 'written' on to a graphene surface using a technique known as Lipid Dip-Pen Nanolithography (L-DPN).
If you have stopped at a gas station recently, there is a good chance your auto has consumed fuel with ethanol blended into it. Yet the price of gasoline is not substantially affected by the volume of its ethanol content, according to a paper co-authored by an MIT economist.
Astrophysicists have found the first evidence of a water-rich rocky planetary body outside our solar system in its shattered remains orbiting a white dwarf. A new study by scientists at the Universities of Warwick and Cambridge published in the journal Science analysed the dust and debris surrounding the white dwarf star GD61 170 light years away.
GC 6240 is an elliptical galaxy that resembles a pale rose in the sky, with hazy shells of stars encircling a very bright centre. Some of these shells are packed close to the centre of the galaxy, while others are flung further out into space. Several wisps of material have been thrown so far that they appear to be almost detached from the galaxy altogether.
Among the ranks of automakers yet to do much with electric vehicles, particularly here in the United States, resides Kia Motors. That looks to be changing soon though, as the Korean automaker announced recently plans to bring its iconic Soul urban passenger vehicle into the EV space sometime next year.
China, with one of the world’s largest populations, remains a market highly untapped by foreign automakers looking to sell electrified vehicles. General Motors is one looking to change that, holding a workshop recently in Shanghai where it showcased some aspects of its long term vehicle electrification strategy.
