How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter. New work from Carnegie scientists has enabled researchers to examine hydrogen under pressures never before possible. Their work is published online in Physical Review...

Imagine being able to use electricity to power your car – even if it's not an electric vehicle. Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have for the first time demonstrated a method for converting carbon dioxide into liquid fuel isobutanol using electricity. Today, electrical energy generated by various methods is still difficult to store efficiently. Chemical batteries, hydraulic pumping and water splitting suffer from low energy-density...

Spanish and Danish researchers have developed a method for the in vivo study of the unknown metabolism of selenium, an essential element for living beings. The technique can help clarify whether or not it possesses the anti-tumor properties that have been attributed to it and yet have not been verified through clinical trials. "It is vox populi that doctors around the world recommend selenium supplements to complement traditional therapy against cancer and the AIDS virus but the truth is...

Iron is key to reversing global warming, Concordia and McGill research shows Canada defines itself as a nation that stretches from coast to coast to coast. But can we keep those coasts healthy in the face of climate change? Yves Gélinas, associate professor in Concordia´s Department of Chemistry and Biochemistry, has found the solution in a surprising element: iron. In a study published in Nature, Gélinas – along with Concordia PhD candidate Karine...

Researchers at the universities of Granada and Barcelona have described for the first time the diffusion of liquid water through nanochannels in molecular terms; nanochannels are extremely tiny channels with a diameter of 1-100 nanometers that scientists use to study the behavior of molecules (nm. a unit of length in the metric system equal to one billionth of a meter that is used in the field of nanotechnology). This study might have an important impact on water desalinization and...

New analyses of more than 4,000 scientific studies have concluded that a family of "miracle materials" called MOFs have a bright future in products and technologies – ranging from the fuel tanks in hydrogen-powered cars to muting the effects of the greenhouse gas carbon dioxide – that are critical for solving some of the greatest global challenges of the 21st century. The 18 articles examining 4,283 pieces of research on MOFs published in the past appear in a special edition of...

Scientists have developed a new kind of tiny motor – which they term a "microrocket" – that can propel itself through acidic environments, such as the human stomach, without any external energy source, opening the way to a variety of medical and industrial applications. Their report in the Journal of the American Chemical Society describes the microrockets traveling at virtual warp speed for such devices. A human moving at the same speed would have to run at a clip of 400 miles...

Thanks to a collaboration between scientists in San Sebastian and Japan, a relay reaction of hydrogen atoms at a single-molecule level has been observed in real-space. This way of manipulating matter could open up new ways to exchange information between novel molecular devices in future electronics. Dr. Thomas Frederiksen, presently working in the Donostia International Physics Center (DIPC) is one of the scientists that has participated in this research project. The results have been...

The appearance of oxygen in the Earth's atmosphere probably did not occur as a single event, but as a long series of starts and stops, according to an international team of researchers who investigated rock cores from the FAR DEEP project. The Fennoscandia Arctic Russia - Drilling Early Earth Project -- FAR DEEP -- took place during the summer of 2007 near Murmansk in the northwest region of Russia. The project, part of the International Continental Scientific Drilling Program,...

Much of our knowledge about past life has come from the fossil record — but how accurately does that reflect the true history and drivers of biodiversity on Earth? "It's a question that goes back a long way to the time of Darwin, who looked at the fossil record and tried to understand what it tells us about the history of life," says Shanan Peters, an assistant professor of geoscience at the University of Wisconsin—Madison. In fact, the fossil record can tell us a great...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
