Purdue creates new low-cost system to detect bacteria

...bute to how a colony distorts light. The procedure identifies a bacterial colony by comparing an image of its scatter pattern against a template that contains 120 features described by Zernike polynomials. "A good analogy is the method used by law enforcement to identify a person's face using specialized reco...

New genetic test for breast cancer

...etwork of cancer research professionals. The test identifies which of 21 specific genes are turned on or off in the tumor. This genetic assessment estimates a patient's risk of recurrence more precisely than standard clinical characteristics, such as tumor size and grade. It also helps predict whether a pati...

New tiger report release: Tiger habitat down from just a decade ago

..., and on-the-ground evidence of tigers, this study identifies 76 "tiger conservation landscapes" ?places and habitats that have the best chance of supporting viable tiger populations into the future. Large carnivore populations like tigers are highly vulnerable to extinction in small and isolated reserves. Hal...

Can biological traits predict diversification rates in birds?

...ens (Imperial College London, Silwood Park Campus) identifies the two biological traits in birds that account for most of the variation: dispersal and feeding generalization. "Few studies have looked at ecological traits such as dispersal and feeding generalization as explanations for variation in rate of dive...

Successful transplantation from pig embryos to mice

... however, they may be too well-developed: The host identifies these cells as foreign, causing the body to reject them. By transplanting tissues from pig embryos into mice lacking proper immune systems, they determined that the best time frame for pancreatic tissue was about a third of the way through gestation ...

Researchers find cause of frontotemporal dementia

...nt. Genetic analyses of the DNA from FTDU families identifies defects that cause a shortage of progranulin. Progranulin is known in cancer research, where a surplus of this protein leads to tumors. What it does in the brain, and how it supports brain cells, is not yet known. An unexpected turn The biologic...

Smell of success for nanobiosensors

... it is the resultant combination of reactions that identifies a certain smell. Nanotechnology makes such an electronic nose feasible, the coordinator notes, even though the human nose uses 1,000 different proteins to allow the brain to recognise 10,000 different smells. While the SPOT-NOSED project focused o...

Higher risk for cervical cancer seen among women infected with multiple HPV types

...hat detects the presence of a HPV co-infection and identifies each HPV genotype. If an infection is present, the current test cannot determine whether it was triggered by just one genotype or multiple types of HPV. Because the HPV test used by Franco and his colleagues could detect more than 40 types of the ...

DOE publishes research roadmap for developing cleaner fuels

...sident's Advanced Energy Initiative. The roadmap identifies the research required for overcoming challenges to the large-scale production of cellulosic ethanol to help meet this goal, including maximizing biomass feedstock productivity, developing better processes by which to break down cellulosic materials i...

UCLA study finds same genes act differently in males and females

...s such as diabetes, heart disease and obesity, and identifies targets for the development of gender-specific therapies," said Jake Lusis, Ph.D., co-investigator and UCLA professor of human genetics. The UCLA team examined brain, liver, fat and muscle tissue from mice with the goal of finding genetic clues rel...

... will be used to find caves on Mars. Once his team identifies Martian caves, robotic cave explorers will be developed to search for life under the Martian surface. His second project involves developing procedures for rapidly inventorying cave biodiversity. He has applied these methods to caves throughout north...

Inflammation markers identify fatigue in breast cancer survivors

...mune response elements," he added. "This biomarker identifies ?and can predict ?which women have long term persistent fatigue. "These findings point the way for development of novel treatment strategies that decrease this inflammatory response and thwart the fatigue that these patients endure." One component...

Two central mysteries in genome inheritance solved at UCSD

... to be published in the December 15 issue of Cell, identifies a different type of connection between chromosomes and microtubule polymers, which operates to discriminate between correct and incorrect chromosome-spindle attachments. Each replicated chromosome is comprised of a pair of identical sister chromati...

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

Our analysis identifies the forces that drive the epidemic in black America, and recommends proven, practical and affordable strategies that government must implement without delay to protect the health of African Americans." "It is a national tragedy that the AIDS cris...

Nanotech tools yield DNA transcription breakthrough

One of the studies reported in Science was conducted by Ebright's laboratory in conjunction with Shimon Weiss' laboratory at th...

Pourquié lab identifies genes involved in formation of vertebral precursors

...st and last authors, respectively, on a paper that identifies a network of cyclic genes that shed light on the molecular basis of spine formation in the embryo. The paper was published on Science Express, the advanced publication Web site of Science Magazine on Nov. 9, 2006. Dr. Pourquié's lab has long ...

Sports cheats beware -- new test detects previously undetectable drug

...print of the molecule ?a fingerprint that uniquely identifies it. "If the drug testing authorities adopt this new test it will close a gap in the current drug testing system, and mean that athletes will no longer be able to get away with this form of cheating," says lead author Mario Thevis, who works in the...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

...edings of the National Academy of Sciences Online, identifies the activity of a critical segment of a viral protein required to sustain EBV-related tumors. The researchers found that when they blocked this activity, the virus life cycle was broken. Often linked to infectious mononucleosis, EBV also causes canc...
