Paired microbes eliminate methane using sulfur pathway
Anaerobic microbes in the Earth's oceans consume 90 percent of the methane produced by methane hydrates - methane trapped in ice - preventing large amounts of methane from reaching the atmosphere. view more (2008-01-17)
NIST's new advanced imaging facility peers inside hydrogen fuel cells
Thanks to a new and improved imaging instrument at the Commerce Department's National Institute of Standards and Technology (NIST), scientists now can conduct detailed surveillance on the comings and goings of water inside hydrogen fuel cells-a piece of intelligence key to making the technology practical for powering future automobiles. view more (2006-08-21)
Hydrogen bonds shown to play 'conserved' role in protein folding
By changing individual atoms in key places in proteins, Duke University chemists have found new evidence for the importance of comparatively weak "hydrogen bonds" in enabling stringlike proteins to fold into the maximally stable shape they need to assume their roles as biological workhorses. view more (2006-02-13)
Naval Research Laboratory to design lunar telescope to see into the dark ages
A team of scientists and engineers led by the Naval Research Laboratory (NRL) will study how to design a telescope on the Moon for peering into the last unexplored epoch in the Universe's history. view more (2008-03-12)
The healing power of Hydrogen Peroxide
Hydrogen peroxide is usually used for cleansing scratches and cuts. However, this is not the only one possible application of this substance in medicine. The vapor of a low-concentrated peroxide solution containing oxygen radicals can be used as an inhalant for an additional treatment of many illnesses. This has been established by the research... view more... (2002-04-19)
New aluminum-rich alloy produces hydrogen on-demand for large-scale uses
Purdue University engineers have developed a new aluminum-rich alloy that produces hydrogen by splitting water and is economically competitive with conventional fuels for transportation and power generation. view more (2008-02-20)
Breaking the Ties that Bind: New Hope for Biomass Fuels
Los Alamos National Laboratory researchers have discovered a potential chink in the armor of fibers that make the cell walls of certain inedible plant materials so tough. view more (2009-04-23)
Poison + water = hydrogen. New microbial genome shows how
Take a pot of scalding water, remove all the oxygen, mix in a bit of poisonous carbon monoxide, and add a pinch of hydrogen gas. It sounds like a recipe for a witch's brew. It may be, but it is also the preferred environment for a microbe known as Carboxydothermus hydrogenoformans. view more (2005-12-05)
Portable power plants
Running a laptop or other electrical equipment causes a problem when there is no access to a mains supply: If the battery runs out, where can you recharge it? This is a particularly thorny issue if, for example, your work takes you out on the road or involves spending lots of time on construction sites. In the long run spare batteries do not... view more... (2003-04-04)
Putting the squeeze on nitrogen for high energy materials
Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen. view more (2008-09-04)
Ion Tiger fuel cell unmanned air vehicle completes 23-hour flight
The Naval Research Laboratory's (NRL's) Ion Tiger, a hydrogen-powered fuel cell unmanned air vehicle (UAV), has flown 23 hours and 17 minutes, setting an unofficial flight endurance record for a fuel-cell powered flight. view more (2009-10-14)
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 a innovative type of porous material. view more (2007-07-31)
Rehydrate - your RNA needs it
Water, that molecule-of-all-trades, is famous for its roles in shaping the Earth, sustaining living creatures and serving as a universal solvent. view more (2006-08-23)
Radio Telescopes Reveal Unseen Galactic Cannibalism
Radio-telescope images have revealed previously-unseen galactic cannibalism -- a triggering event that leads to feeding frenzies by gigantic black holes at the cores of galaxies. Astronomers have long suspected that the extra-bright cores of spiral galaxies called Seyfert galaxies are powered by supermassive black holes consuming material.... view more... (2008-06-24)
Jupiter's rocky core bigger and icier, model predicts
Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms. view more (2008-11-26)
Diamonds from outer space — Geologists discover origin of Earth's mysterious black diamonds
If indeed "a diamond is forever," the most primitive origins of Earth's so-called black diamonds were in deep, universal time, geologists have discovered. Black diamonds came from none other than interstellar space. view more (2007-01-10)
Weizmann Institute Scientists Develop a Unique Approach for Splitting Water into Hydrogen and Oxygen
The design of efficient systems for splitting water into hydrogen and oxygen, driven by sunlight is among the most important challenges facing science today, underpinning the long term potential of hydrogen as a clean, sustainable fuel. view more (2009-04-07)
Cellular organelle evolved repeatedly
NWO researchers have discovered that in the course of evolution hydrogenosomes repeatedly evolved from mitochondria. Hydrogenosomes, or 'hydrogen-forming organelles', are cell organelles that produce hydrogen and energy. They serve as an alternative energy supply in organisms that live without oxygen, such as anaerobic fungi and protozoa. The... view more... (2001-07-26)
'Sewer gas' induces suspended animation without decreasing blood pressure
Hydrogen sulfide gas can induce a state of suspended animation in mice while maintaining normal blood pressure, a finding that researchers hope will one day help treat critically-ill patients. view more (2006-10-09)
Green catalysts provide promise for cleaning toxins and pollutants
Tetra-Amido Macrocyclic Ligands (TAMLs) are environmentally friendly catalysts with a host of applications for reducing and cleaning up pollutants, and a prime example of "green chemistry." Carnegie Mellon University's Terry Collins, the catalyst's inventor, believes that the small-molecule catalysts have the potential to be even more... view more... (2008-08-18)
