Internet viruses help ecologists control invasive species

...adian lakes. Using network theory, they built up a picture of the lakes as nodes in a network connected by human traffic, including boat trailers and anglers. Like internet viruses, which spread fastest when they attack the most widely-used email programmes, Muirhead and MacIsaac examined patterns of human v...

Gov't Creates Gene Database of Normal Human Tissues

...t to a baseline standard that represents a generic picture of normal gene activity, organ by organ, in the human body. Users of the array on the new NCI web site (http://home.ccr.cancer.gov/oncology/oncogenomics/) will find expression profiles for 18,927 genes, which include most of the genes that are known ...

Affymetrix Launches New Globin-Reduction Kits and Protocol Developed with PreAnalytiX

...f whole blood cellular RNA profiles. "An accurate picture of in vivo gene expression profiles is essential for understanding gene regulation as it relates to different disease states and a patient's response to drug therapy," said Noel Doheny, Vice President of PreAnalytiX and QIAGEN. "We continue to see a ...

Stanford gut check shows diversity of intestinal ecosystem

...e to which an individual determines the particular picture of microbial diversity that we see," said Relman. "Variation between individuals had been suspected, but our data proved to be a dramatic confirmation of this belief." An interesting corollary of this finding is that the ability to create a comprehe...

...or and Ecology of Pacific Salmon and Trout." Just picture that tiny male under the belly of a 20-pound adult female that's returned to spawn, Quinn says. He's almost as likely to be a "winner" as the full-size males that are releasing their sperm in a competitive frenzy as the female deposits her eggs. And...

Duke engineers develop new 3-D cardiac imaging probe

...Inserted inside the esophagus, the probe creates a picture of the whole heart in the time it takes for current ultrasound technology to image a single heart cross section. The new probe has considerable potential not only for evaluating the condition of the heart, but also for use in guiding therapeutic tre...

This study was done in collaboration with Diversa Corporation of San Diego, Calif. who provided the DNA from the different environments which included soil from a Minnesota farm and samples of several different whal...

Computational Method Speeds Mapping of Cell Signaling Networks

...ing the information together to construct a global picture of what’s going on inside the cell. But the molecules that make up individual pathways in signaling networks rarely operate in isolation--they "talk" to each other and work in sync to process information. What researchers have lacked are the experime...

Great White shark evolution debate involves WSU Lake Campus geology professor

He even uses an electron microscope to view different serration designs of shark teeth. "Our analysis of their teeth shows that Great White and mako ...

Chemists identify immune system mechanism for methamphetamine binges

Their study, which paints a clearer picture of the drug's effect on the immune system and its potential for abuse, was described today at the 229th national meeting of the American Chemical Society, the world's largest scientific society. "Test animals injected with methamphetamine actually d...

Programmable cells: Engineer turns bacteria into living computers

Ed : Sadly no picture is available; however, you can find one in an article from last year , describing the group's research. In a step toward making living cells function as if they were tiny computers, engineers at Princeton have programmed bacteria to communicate wi...

Scientists find fossil proof of Egypt's ancient climate

...e of the lake. Their analyses support a surprising picture of arid Egypt: 130,000 years ago, what everyone considers an eternal desert was actually a thriving savannah, complete with humans, rhinos, giraffes and other wild life. Evidence for the hominin presence abounds near the lake in the form of Middle S...
