U of M researchers invent 'flashy' new process to turn soy oil, glucose into hydrogen

...available to make syngas and hydrogen." Schmidt gained national attention in February 2004, when a team he headed invented a similar apparatus to produce hydrogen from ethanol. ...

Key to zebrafish heart regeneration uncovered

...some species, rather than an ability that has been gained by other species. The key is to find a way to 'turn on' this regenerative ability." The research was supported by the National Institutes of Health, the American Heart Association, the March of Dimes and the Whitehead Foundation. Scientists pre...

Genome info from 'plant destroyers' could save trees, beans and chocolate

...e ineffective at controlling them. The information gained from studying the genomic sequences of P. ramorum and P. sojae will help scientists devise strategies to combat not only these two species, but also other disease-causing Phytophtora. The study appears in the Sept. 1 issue of the journal Science. P...

Ocean sampling yields environmental sources of coral symbionts

...sive but critical group of algae, researchers have gained new insight into the dwelling places of the symbiotic organisms that reef corals need for survival. The symbiosis between special algal species and reef corals is the foundation of a highly productive and biologically complex ecosystem, but our unde...

Cities change the songs of birds

...ceeded in adapting to urban life, researchers have gained insight into the kinds of environmental pressures that influence where particular songbirds thrive, and the specific attributes of city birds that allow them to adjust to noisy urban environments. The findings, reported by Hans Slabbekoorn and Ardie ...

How mammals fuel milk production may have implications for cancer

...ers reported, the offspring of Akt2-deficient mice gained weight normally. The researchers further showed that the mice without Akt1 displayed a four-fold reduction in milk secretion compared to either normal mice or mice lacking Akt2. The findings represent some of the first to reveal functional diff...

Eating protein boosts hormone that staves off hunger

...heir PYY levels. Mice fed a high-protein diet also gained less weight and produced more PYY than animals that ate the usual amount of protein, they found. In addition, the researchers found that genetically modified mice unable to produce PYY ate more and became markedly obese. The genetically modified mi...

End of deforestation in view? Experts advance new way to size up global forest resources

...horizontal line. Nations above the diagonal line gained growing stock. The authors say Japan's forest c...same time. Says economist Dr. Sedjo: "The USA gained growing stock during 1990 to 2005 while harvesting much round wood and some fuel. China did likewise...

Muscle and bone from an ink-jet printer

... Working with mice, the Pittsburgh biologists have gained considerable experience in using growth factors to control proliferation and differentiation in populations of “muscle-derived stem cells,?or MDSCs. Previous work by University of Pittsburgh researchers has demonstrated the ability of MDSCs to repair...

Plant-derived molecules, genetic manipulation point to future chemoprevention methods

...iment were apparently well tolerated, and the mice gained weight throughout the experiment," Liby said. "These studies indicate that CDDO-ME and LG100268, even as individual drugs, can delay tumor development in living organisms. But the combination of the triterpenoid and rexinoid compounds was particularl...

SARS: No evidence that any of the treatments worked

...mean cost per disability-adjusted life year (DALY) gained by the DOTS-Plus project was US$242 (range US$85 to US$426). In a related perspective, Paul Garner and colleagues from the Liverpool School of Hygiene and Tropical Medicine assess the implications of these findings further, especially whether they ca...

New mechanism underlying pain found

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...Mars has captured the imagination for decades, and gained force after the Astronaut Neil Armstrong took his first step on the moon in 1969. But flying to Mars, even without humans aboard, is a monumentally risky engineering feat. Since 1998, the United States has completed seven Mars missions. Four failed w...

A giant among minnows: Giant danio can keep growing

... zebrafish. “One of these species either lost or gained the ability to continuously grow, but most likely, the zebrafish lost it?Biga explained. Because genes are the key, the zebrafish’s mapped genome will be invaluable in finding what is different about the danio’s genetic pathways that allow it to keep...

Finding the right mix: A biomaterial blend library

...a difficult and time-consuming task. As the blends gained a higher or lower proportion of a respective material, the cells around them react by changing shape, ultimately increasing or decreasing contact with the films. In the body, such cell-material dynamics are critically important to the outcome--determ...

How nature tinkers with the cellular clock

...e regulation of each mechanism." The new insights gained have broad implications. The principles discovered might govern also the control of other temporally regulated systems like embryonic development. The fast evolution of temporal regulation also raises the question in how far general conclusions about...

Bacteria could make new library of cancer drugs that are too complex to create artificially

...myces coelicolor to create streptorubin B and have gained a clear understanding of which are the key enzymes that act at particular steps of that process. By manipulation of the enzyme content of the bacteria, they aim to produce a range of different compounds based closely on the form of streptorubin B nor...

Study provides first look at the 'birth' of a retina cell

...the University of Michigan Kellogg Eye Center have gained new insight into the way an embryonic retina cell develops and then commits itself to a specific role. They have observed a small window of opportunity during which a cell has been designated to play a particular role, but has not yet begun to functi...

Just like us, social stress prompts hamsters to overeat, gain weight

...der hamsters subsequently: ate significantly more gained significantly more weight gained significantly more fat, including visceral fat These results occurred when the intruder hamsters w...

A surprise about our body clock

...o-author in this study. "Based on the knowledge we gained from this study, we can now design new strategies to enhance normal repair and regeneration for patients who suffered a heart attack." This concept is central to the exciting new field called regenerative medicine which aims to restore, repair and re...
