Study of genomic DNA leads to new advances in cancer diagnostics

... the clinical setting. Physicians and researchers alike know that how a cancer cell interacts with its microenvironment is important for cancer progression. Such interactions must be aberrant for abnormal cell growth and metastasis to occur. Indeed, Dr. Maniotis and his colleagues found that the extracell...

Different microarray systems more alike than previously thought

...s these different microarray technologies are more alike than once thought. Published in the May 2005 issue of Nature Methods, the study provides new hope that the mounds of information generated by these systems might actually be comparable, even though many different systems are used by many different l...

Brain Scan Study of Smokers Reveals Signature of Craving

Not all smokers are alike when it comes to cravings, and a new study conducted by researchers at Duke University Medical Center suggests the difference may lie in their brains' sensitivity to drug cues. The researchers found that smokers who report a greater urge to smoke aft...

Could better mangrove habitats have spared lives in the 2004 tsunami?

...termath of the disaster, academics and politicians alike are trying to investigate how the number of casualties could have been reduced and, more important, how such severe damage can be avoided if a tsunami ever strikes again.

"We found that when the dominating male is removed, the subordinate male perceives an opportunity to advance in social status and responds both behaviorally ...

Creeping crinoids! Sea lilies crawl to escape predators, new video shows

...urchins. The two main types of crinoids look a lot alike except that sea lilies have stalks, and feather stars do not. In addition, feather stars are known to crawl, and some can even swim, but sea lilies were thought not to have such abilities. However, Baumiller and collaborator Charles Messing of Nova...

Research: Snails were overlooked contributors to marsh destruction

...ced flood and erosion. So scientists and citizens alike watched with alarm as the marshes started dying off from Louisiana to South Carolina beginning in 1999. Most earlier research pointed to the effects of a severe drought as the cause. The drought dried up soils, raised their acidity and boosted estuar...

World faces challenge as life expectancies lengthen, scientist says

... stressed the need for scientists and policymakers alike to confront the full environmental and sociological implications of anti-aging technologies, with an awareness of the potential costs and challenges in addition to the benefits. "What we've tended to do historically with medical advances is to take ...

Junk DNA may not be so junky after all

... regions from different species don't have to look alike to work alike. The study will be published online at Science Express March 23. The researchers developed a new system that uses zebrafish to test mammalian DNA and identify DNA sequences, known as enhancers, involved in turning on a gene. In studyi...

"They pretty much wipe out all of the rooted aquatic plants, they eat fish eggs, they either eat or compete with native invertebrates and, in general, raise havoc with the near-shore community of a lake," says Stephen Carpenter, a UW-M...

Scientists use gene signatures to match cancer and other diseases with potentially effective drugs

...mpanies, so that academic scientists and companies alike can compare the signatures of diseases and compounds to signatures in the Connectivity Map database, and, from that, generate hypotheses," Golub said. The strategy allows scientists to capture distinctive gene signatures of cancer and other disease...

Recurrence of a flu pandemic similar to infamous 1918 flu could kill 62 million

...years, health professionals and the general public alike have been acutely aware of the potential ravages that could result from a flu pandemic. Although many people might still recall the pandemics of 1968 and 1957, it is the infamous 1918-1920 pandemic--and the possibility of a recurrence on that scale--...

Cells use 'noise' to make cell-fate decisions
