Mutating the entire genome

...d for mutating large, non-gene stretches of DNA is outlined in this week’s online edition of Nature Genetics. Capecchi and Wu conducted the research with two other University of Utah human geneticists: Guoxin Ying, a postdoctoral fellow, and Qiang Wu, an assistant professor (and no relation to Sen Wu). In...

Brain's white matter -- More 'talkative' than once thought

...ay matter cells do. The discovery in mouse cells, outlined in the cover story of the March issue of Nature Neuroscience, shows that brain cells “talk?with each other in more ways than previously thought. “We were surprised to see these nerve axons talking to other cells in the white matter,?says Dwight B...

Newly identified mechanism for silencing genes points to possible anti-cancer strategies

...n implicated in a number of cancers, and the newly outlined gene-silencing mechanism offers promising potential targets for anti-cancer interventions. "Some microRNAs closely match their sequences against particular messenger RNA sequences to target them for destruction," explains Ramin Shiekhattar, Ph.D.,...

Leeches ferry infection among newts

... mouthparts of a feeding leech. Their findings are outlined in the January issue of Journal of Parasitology. In 2004, Raffel and his Penn State colleagues Peter J. Hudson, professor of biology, and James R. Dillard, then an undergraduate student and now with the Pennsylvania Department of Environmental Pr...

FSU researchers determine a critical factor in workings of proteins

...the association rate for proteins. Their theory is outlined in the February issue of the scientific journal Structure. "A protein can have multiple targets or can be targeted by multiple molecules," said Professor Huan-Xiang Zhou, who serves on the faculty of FSU's School of Computational Science and depar...

Custom-made cancer cell attacks

... State of the Union address, President George Bush outlined his plan to reduce the nation's dependency on foreign oil by requiring the production of 35 billion gallons a year of renewable and alternative fuels by 2017, roughly five times the current target set by Congress of 7.5 billion gallons by 2012. Amon...

Cellulosic ethanol: Fuel of the future?

... State of the Union address, President George Bush outlined his plan to reduce the nation's dependency on foreign oil by requiring the production of 35 billion gallons a year of renewable and alternative fuels by 2017, roughly five times the current target set by Congress of 7.5 billion gallons by 2012.

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...dent and chief fossil officer, TXU Power. “TXU has outlined a vision to lower carbon dioxide emission rates through development of new technologies, and Dr. Rochelle’s research will undoubtedly make great strides toward this development.? Rochelle spent the past six years developing the technology with fund...

Satellites shed light on global warming

...vation Science at the University of Leicester, UK, outlined the importance of SST data at the symposium. Tracking SST over a long period is arguably the most reliable way researchers know of measuring the precise rate at which global temperatures are increasing and improves the accuracy of our climate cha...

Edible coatings will be the packaging of the future

...igh relative humidity. The final part of the PhD outlined the application of edible coatings with WPI on chicken breasts. The aim was to analyse the effect on their aspect and their properties. At the same time, the experiment was used to incorporate nisine, an antioxidant agent that penetrates the foodstuf...

Plants give up answers in the war on bacteria

...lants. Last month, in Science Magazine, the lab outlined a better understanding of how bacteria set up camp and destroy the plant's ability to fight infection. The work was funded by the National Institutes of Health and the U.S. Department of Energy and supported by the Michigan Agricultural Experiment ...

Shrinking ponds signal warmer, dryer Alaska

...from the Landsat satellite from 1999-2002, Riordan outlined each pond by hand. "With automated classification your accuracy goes down," Riordan said. Cloud shadows can look like water and Alaska rarely experiences a cloudless day, said Verbyla. The most difficult part of the four-year project, said Riordan,...

Novel regulatory mechanism identified for key tumor suppressor p53

...lability of a repressive mechanism such as the one outlined in the new study might be crucial for cellular survival. "You can imagine that if the p53 protein were present at all times and able to bind to DNA, cells would be in big trouble," Berger explains. "They wouldn't be able to divide, and they'd die. ...

New HIV statistics indicate increasing toll of AIDS on African American community

...is in the African-American community. The plan is outlined in a new report, African-Americans, Health Disparities and HIV/AIDS: Recommendations for Confronting the Epidemic in Black America, written by Robert E. Fullilove, EdD, associate dean for Community and Minority Affairs and professor of Clinical Socio...

'Smart' genetic therapy helps the body to heal itself

... cells' own ability to correct themselves, will be outlined today (Monday 8 May 2006) at the annual conference of the European Society of Human Genetics in Amsterdam, The Netherlands. Instead of replacing a faulty gene (commonly referred to as gene therapy) these new 'smart' approaches make use of the th...

A new view on Lyme disease: Rodents hold the key to annual risk

...ariables with documented effects into the approach outlined here. Also surprising, the researchers found that even a 3-fold variation in deer numbers had no impact on subsequent nymph abundance. Density of infected nymphs--the principal determinant of Lyme disease risk--varied significantly from year to ye...

Microbe has huge role in ocean life, carbon cycle

...blication today in the journal Science, scientists outlined the growing knowledge about SAR11, a group of bacteria so dominant that their combined weight exceeds that of all the fish in the world's oceans. In a marine environment that's low in nutrients and other resources, they are able to survive and replic...

UCLA cancer researchers shake loose hidden biomarker

...to another, easier to target area. The discovery, outlined in the cover article of May 11 edition of the peer-reviewed journal Molecular Cancer Therapeutics, could have important implications for using immunotherapy to treat prostate cancer, said Ayyappan K. Rajasekaran, a Jonsson Cancer Center researcher an...

Human Cells Filmed Instantly Messaging for First Time

...each 80 billion gallons or more under the scenario outlined in this report. Such an increase in ethanol production would see transportation fuels from biomass increase from 0.5 percent of U.S. consumption in 2001 to 4 percent in 2010, 10 percent in 2020 and 20 percent in 2030. In fact, depending on several fa...
