A new catalyst makes hydrogen from ethanol with 90 percent yield, at a workable temperature, and using inexpensive ingredients. The new catalyst is much less expensive than others being developed around the world, because it does not contain precious metals, such as platinum or rhodium.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370507964" height="1" width="1"/> Thu, 21 Aug 2008 14:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820163111.htm http://www.sciencedaily.com/releases/2008/08/080820163111.htm Oetzi The Iceman Dressed Like A Herdsman http://feeds.sciencedaily.com/~r/sciencedaily/~3/370507965/080820194843.htm A famous Neolithic Iceman is dressed in clothes made from sheep and cattle hair, a new study shows.

Because drugs that increase dopamine, like amphetamines, promote wakefulness, the findings offer a potential mechanism explaining how the brain helps people stay awake despite the urge to sleep. However, the study also shows that the increase in dopamine cannot compensate for the cognitive deficits caused by sleep deprivation.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370475456" height="1" width="1"/> Thu, 21 Aug 2008 11:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080819213033.htm http://www.sciencedaily.com/releases/2008/08/080819213033.htm Creating Unconventional Metals: Quantum Halfway House Between Magnet And Semiconductor Discovered http://feeds.sciencedaily.com/~r/sciencedaily/~3/370313404/080820162856.htm The semiconductor silicon and the ferromagnet iron are the basis for much of mankind's technology, used in everything from computers to electric motors. Scientists now report that they have combined these elements with a small amount of another common metal, manganese, to create a new material which is neither a magnet nor an ordinary semiconductor.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370313404" height="1" width="1"/> Thu, 21 Aug 2008 08:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820162856.htm http://www.sciencedaily.com/releases/2008/08/080820162856.htm Making 'Good' Fat From Muscle And Vice Versa http://feeds.sciencedaily.com/~r/sciencedaily/~3/370349107/080820162852.htm A surprise discovery -- that calorie-burning brown fat can be produced experimentally from muscle precursor cells in mice -- raises the prospect of new ways to fight obesity and overweight, report Dana-Farber scientists. They demonstrated that a previously known molecular switch, PRDM16, regulates the creation of brown fat from immature muscle cells. They also determined that the process is a two-way street: Knocking out PRDM16 in brown fat cells can convert them into muscle cells.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370349107" height="1" width="1"/> Thu, 21 Aug 2008 08:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820162852.htm http://www.sciencedaily.com/releases/2008/08/080820162852.htm New Test To Diagnose Osteoarthritis Early http://feeds.sciencedaily.com/~r/sciencedaily/~3/370475457/080820162844.htm A newly developed medical imaging technology may provide doctors with a long-awaited test for early diagnosis of osteoarthritis, according to researchers. By far the most common form of arthritis, OA causing joint pain and disability for more than half of those over age 65 -- nearly 21 million people in the United States alone, the scientists say. Their study will be presented in August at the American Chemical Society national meeting in Philadelphia.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370475457" height="1" width="1"/> Thu, 21 Aug 2008 08:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820162844.htm http://www.sciencedaily.com/releases/2008/08/080820162844.htm Brain Cells Called Astrocytes Undergo Reorganization And May Engulf Attacking T Cells http://feeds.sciencedaily.com/~r/sciencedaily/~3/370507969/080820163245.htm When virally infected cells in the brain called astrocytes come in contact with antiviral T cells of the immune system, they undergo a unique series of changes that dramatically reorganize their shape and function, according to researchers. Intriguingly, the new data indicate that astrocytes may defend themselves from attacking T cells by engulfing (gobbling up) the aggressors.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370507969" height="1" width="1"/> Thu, 21 Aug 2008 08:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820163245.htm http://www.sciencedaily.com/releases/2008/08/080820163245.htm Polymer Electric Storage, Flexible And Adaptable http://feeds.sciencedaily.com/~r/sciencedaily/~3/370507970/080820163105.htm The proliferation of solar, wind and even tidal electric generation and the rapid emergence of hybrid electric automobiles demands flexible and reliable methods of high-capacity electrical storage.

But do black holes also come in size medium? A new study suggests that, for the most part, the answer is no.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370507971" height="1" width="1"/> Thu, 21 Aug 2008 05:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820210740.htm http://www.sciencedaily.com/releases/2008/08/080820210740.htm Removing Tumors Through The Nose: Neurosurgeon Uses Smaller Openings To Reach The Brain http://feeds.sciencedaily.com/~r/sciencedaily/~3/370507972/080820162951.htm Dr. Edward Duckworth is part of a new generation of neurosurgeons who are making brain surgery a lot easier on patients. Rather than cutting out large sections of the skull or face, Duckworth is reaching the brain through much smaller openings. And in certain cases, he goes through the nose to get to the brain.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370507972" height="1" width="1"/> Thu, 21 Aug 2008 05:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820162951.htm http://www.sciencedaily.com/releases/2008/08/080820162951.htm Tailor-made Functional Garments For Olympic Horses http://feeds.sciencedaily.com/~r/sciencedaily/~3/370475459/080820081203.htm When the horses and competitors go through their paces at the Summer Olympics in Hong Kong in 2008, it will be very hot and very humid -- just as it is every summer there. Three special blankets will offer the Swiss teams' tournament horses some respite from the elements.

They also found that location mattered: sales were more likely if the attempt took place in the stadium stands rather than at a concession booth.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370475461" height="1" width="1"/> Thu, 21 Aug 2008 05:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820162848.htm http://www.sciencedaily.com/releases/2008/08/080820162848.htm Study Identifies Protein That Produces 'Good' Fat: Finding May Lead To Ways To Treat, Prevent Obesity http://feeds.sciencedaily.com/~r/sciencedaily/~3/370349106/080820162850.htm A study by researchers at the Joslin Diabetes Center has shown that a protein known for its role in inducing bone growth can also help promote the development of brown fat, a "good" fat that helps in the expenditure of energy and plays a role in fighting obesity.<img src="http://feeds.sciencedaily.com/~r/sciencedaily/~4/370349106" height="1" width="1"/> Thu, 21 Aug 2008 02:00:00 EDT http://www.sciencedaily.com/releases/2008/08/080820162850.htm http://www.sciencedaily.com/releases/2008/08/080820162850.htm Codeine Not Safe For All Breastfeeding Moms And Their Babies http://feeds.sciencedaily.com/~r/sciencedaily/~3/370507974/080820162858.htm Using pain treatments which contain codeine may be risky for some breastfeeding mothers, according to new research.

Mice exposed to tobacco smoke infected with the common lung pathogen Myclplasma pneumoniae fail to mount the protective antioxidant response in the lungs that mice do when exposed to tobacco smoke alone.
