Beyond the book: Software automates access to brain atlases

...e Swanson's involved continual back and forth page turning and index consulting. Page turning means that researchers can't look at two or three or five images side by side or on top of each othe...

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

...eforestation to afforestation, raising hopes for a turning point for the world as a whole, according to researchers advancing a more sophisticated approach to measuring forest cover. The novel approach looks beyond simply how much of a nation's area is covered by trees and considers the volume of timber, bi...

'Erectile dysfunction' drugs heighten natural anti-cancer activity

...cancers to avoid detection by the immune system by turning elements of that system to its own advantage, says Ivan Borrello, M.D., assistant professor at the Johns Hopkins Kimmel Cancer Center. Borrello and his colleagues found that tumors exploit nitric oxide-producing immune cells to create a sort of "...

LSD treatment for alcoholism gets new look

... also know as DTs, often marked a "rock bottom" or turning point in the behavior of alcoholics, and they felt LSD may be able to trigger such a turnaround without engendering the painful physical effects associated with DTs. As it turns out, they were largely correct. "The LSD somehow gave these peop...

Researchers identify a key regulator for skin stem cells

By turning on a single gene, researchers can prevent skin ste... when the skin is embryonic," said Nguyen. "So, by turning on Tcf3, we were essentially reverting the postnatal skin cells to be more similar to embryonic skin...

...e continually replaced by calling up reserves, and turning these into the blood cell types needed by the body. Claus Nerlov and his colleagues at the European Molecular Biology Laboratory (EMBL) unit in Monterotondo, Italy, in collaboration with researchers from Sten Eirik Jacobsen's laboratory at the Unive...

Neuron cell stickiness may hold key to evolution of the human brain

...ic sequence changes that have a high likelihood of turning genes on and off." Homo sapiens share more tha...rs, the sequence is likely to function as a switch turning genes on or off. In this latest study, he and his Science co-authors investigated whether CNSs also...

Antibiotic inhibits cancer gene activity

... on the study. The FoxM1 gene is responsible for turning on genes needed for cell proliferation and turning off genes that block proliferation. Uncontrolled proliferation is characteristic of cancer cells. ...

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

...sual products: carbon and water. A difficulty in turning plant material into usable fuels has been breaking down the chemical bonds in cellulose--the material that gives plant cell walls their stiffness--to liberate simple sugars that can be fermented into ethanol or turned into other fuels. That requires ...

'Exercise pill' switches on gene that tells cells to burn fat

...s to burn fat. Even when the mice are not active, turning on the chemical switch activates the same fat-burn...master regulator of fat metabolism. By permanently turning on this delta switch in mice through genetic engineering, he was able to create a mouse with an inna...

Reactivated gene shrinks tumors

...p53 turns back on. The study also revealed that turning on p53 has no damaging effects in normal cells. The researchers had worried that p53 would kill normal cells because it had never been expressed in those cells. "This means you can design drugs that restore p53 and you don't have to worry too much...

Walking molecule now carries packages

...hraquinone is widely used in the pulp industry for turning cellulose from wood into paper. It is also the parent substance of a large class of dyes and pigments. Its chemical formula is C14H8O2. The UCR study used a scanning tunneling microscope in Bartels's laboratory that gives a precise picture of indiv...

Stanford scientists make major breakthrough in regenerative medicine

Can engineered immune cells stop AIDS?

...rs in the USC Viterbi School of Engineering may be turning a corner. With support from a $13.9 million grant from the Bill and Melinda Gates Foundation, a multi-institutional team of scientists, including Pin Wang of the USC Mork Family Department of Chemical Engineering and Materials Science, is exploring ...

Cancer researchers add spice to research against rare neuromuscular disease

...This smothers CBP's normal activity which involves turning on another molecule known as VEGF, a growth factor that is crucial for life and essential to the health of motor neurons. Chang's team found that ASC-J9 breaks up the clumps by separating the androgen receptor from some of its helper molecules, or...

Scientists map key landmarks in human genome

...s suggest that nucleosome positioning controls the turning on or off of genes, and the nucleosomes can be relocated if cellular needs change. Fisher, who heads Dana-Farber's Melanoma Program and is a professor of pediatrics at Harvard Medical School, conducts basic research on gene mutations involved in t...

New biofuels process promises to meet all US transportation needs

... W. Nicholas Delgass. A conventional method for turning biomass or coal into liquid fuels involves first breaking down the raw material with a chemical process that "gasifies" it into carbon dioxide, carbon monoxide and hydrogen. Then those constituents are turned into a liquid fuel with other processes. ...

Turning green gunk to gold, anti-cancer gold

... and researcher Zachary Q. Beck found the trick to turning the green gunk into gold---cancer fighting gold. "It was simply too difficult to use the native blue-green algae for high-level production using traditional fermentation approaches," said Sherman. But the compound, called cryptophycin 1, held so ...

Progress toward artificial photosynthesis?

...ntonietti’s team worked with metal-free catalysts, turning toward plants for inspiration. Photosynthesis in modern green plants involves an important intermediate step: the bonding of CO2 to nitrogen atoms to form carbamates. The German researchers thus also experimented with nitrogen-rich catalysts with str...

Bacteria control how infectious they become, study finds

...Molecular Cell. Gene expression ?the process of turning on, or activating, genes ?is controlled by proteins called transcription factors. Every type of bacteria known to humankind contains the transcription factor NusG, which controls nearly all of a bacterium's gene expression. Without it, a microorganis...
