Carbon joins the magnetic club
The exclusive club of magnetic elements officially has a new member—carbon. Using a proton beam and advanced X-ray techniques, researchers at the Department of Energy's Stanford Linear Accelerator Center (SLAC) in collaboration with colleagues from the University of Leipzig and Lawrence Berkeley National Laboratory have finally put to rest doubts about carbon's ability to be made magnetic. The results appeared in the May 4 edition of Physical Review Letters.
New process generates hydrogen from aluminum alloy to run engines, fuel cells
A Purdue University engineer has developed a method that uses an aluminum alloy to extract hydrogen from water for running fuel cells or internal combustion engines, and the technique could be used to replace gasoline.
Novel sugar-to-hydrogen technology promises transportation fuel independence
The hydrogen economy is not a futuristic concept. The U.S. Department of Energy's 2006 Advance Energy Initiative calls for competitive ethanol from plant sources by 2012 and a good selection of hydrogen-powered fuel cell vehicles by 2020.
Detecting cold, feeling pain: study reveals why menthol feels fresh
Scientists have identified the receptor in cells of the peripheral nervous system that is most responsible for the body's ability to sense cold.
New study examines 'brain's own marijuana'
A researcher at the University at Buffalo's Research Institute on Addictions (RIA) is investigating the "brain's own marijuana" -- called endocannabinoid -- in the regulation of stress, stress-related behavior and anxiety.
Professor makes proteins from scratch
Nature, through the trial and error of evolution, has discovered a vast diversity of life from what we can only presume to have been a primordial pool of building blocks. Inspired by this success, a new Biodesign Institute research team, led by John Chaput, is now trying to mimic the process of Darwinian evolution in the laboratory by evolving new proteins from scratch.

Scientists propose the kind of chemistry that led to life
Before life emerged on earth, either a primitive kind of metabolism or an RNA-like duplicating machinery must have set the stage – so experts believe. But what preceded these pre-life steps?
Plastic that grows on trees
It has been an elusive goal for the legion of chemists trying to pull it off: Replace crude oil as the root source for plastic, fuels and scores of other industrial and household chemicals with inexpensive, nonpolluting renewable plant matter.

Engineers develop higher-energy liquid-transportation fuel from sugar
Plants absorb carbon dioxide from the air and combine it with water molecules and sunshine to make carbohydrate or sugar. Variations on this process provide fuel for all of life on Earth.
Tough tubes: carbon nanotubes endure heavy wear and tear
The ability of carbon nanotubes to withstand repeated stress yet retain their structural and mechanical integrity is similar to the behavior of soft tissue, according to a new study from Rensselaer Polytechnic Institute.
New light cast on key chemical reactions in interstellar space
A detailed understanding of key chemical reactions that take place in interstellar space has been provided by groundbreaking research at two U.S. Department of Energy national laboratories and two European universities.
Flavonoids in orange juice make it a healthy drink, despite the sugar
Orange juice, despite its high caloric load of sugars, appears to be a healthy food for diabetics due to its mother lode of flavonoids, a study by endocrinologists at the University at Buffalo has shown.
Synthetic adhesive mimics sticking powers of gecko and mussel
Geckos are remarkable in their ability to scurry up vertical surfaces and even move along upside down. Their feet stick but only temporarily, coming off of surfaces again and again like a sticky note. But put those feet underwater, and their ability to stick is dramatically reduced.
Surprisingly, chemists find, some solvents can alter chemical bonds
New University at Buffalo research demonstrates that some solvents can significantly enhance certain acid-base interactions and strengthen the bonding interaction between two molecules when one is electron-deficient and one is electron-rich.
New aerogels could clean contaminated water, purify hydrogen for fuel cells
Scientists at the U.S. Department of Energy's Argonne National Laboratory have identified a new technique for cleansing contaminated water and potentially purifying hydrogen for use in fuel cells, thanks to the discovery of an innovative type of porous material.
Ceramic tubes could cut greenhouse gas emissions from power stations
Greenhouse gas emissions from power stations could be cut to almost zero by controlling the combustion process with tiny tubes made from an advanced ceramic material, claim engineers.
Nano-boric acid makes motor oil more slippery
One key to saving the environment, improving our economy and reducing our dependence on foreign oil might just be sitting in your mother's medicine cabinet.
Mit team cooks up simple fuel recipe
MIT student Jules Walter has seen firsthand the impact of deforestation in his native Haiti: Nearly 98 percent of the island's forests are gone, and more trees are being cut down every year.
