Found -- the apple gene for red

...looking for requires light to be activated." "By identifying master genes that were activated by light, Adam was able to pinpoint the gene that controls the formation of anthocyanins in apples, and we found that in green apples this gene is not expressed as much as in red apples." In collaboration with apple...

Report highlights change in Canada's forests

... are in its use, and how forward-looking we are at identifying product and market opportunities," said Minister Lunn. "Canada's New Government is committed to helping the Canadian forest industry build a stronger future. We will work with industry to develop new markets and increase access in existing markets, c...

Scientist works to improve treatment for brain tumors

...Ph.D., will explore that question with the goal of identifying which area of the tumor to focus on to achieve maximum results. The drug is delivered to the tumor through small cathethers, allowing physicians to determine the amount and specific location of treatment. "With the help of this research grant, we ho...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...d the muscle cells to use more energy. Therefore, identifying molecules that interact with malonyl-CoA will help scientists understand how energy balance and body weight is controlled. "We are beginning to understand what the hypothalamus inputs are, but unlike the liver, where nearly the whole organ is involv...

Gut reaction: Researchers define the colon's genome

...e. "This study is an important first step toward identifying microbial differences between healthy people and those with conditions ranging from Crohn's Disease to cancer," says co-author Karen Nelson of TIGR, who has previously studied the guts of termites and other animals. "We might compare different indivi...

Major cancer study aims to identify protein markers for early-stage disease

...CI) to refine and standardize the technologies for identifying biomarkers in the blood -- specific proteins, and ...d in the research into recognizable molecules, and identifying patterns of proteins within given blood samples. The need to standardize mass spectrometry is grea...

The brain's motivation station

...vity. In the first task, the researchers aimed at identifying the region involved in anticipating rewards. This task involved presenting the subjects with such symbols as circles or squares that indicated an amount of money the subjects could gain or lose--from no money to $5--by rapidly responding to a subsequ...

Learning the language of DNA

...art of understanding the language of cells lies in identifying promoters - the DNA regions at the start of genes that regulate their activity. "We have identified the core promoters of the large majority of genes in the mouse and human genomes, expanding the number of known promoters by five- to ten-fold," Pro...

New strategy developed to combat West Nile Virus

... a number of factors that lead to that stage. "By identifying these factors in the wild, it will enhance our ability to create control strategies." In their studies, Shaman and colleague Jonathan F. Day from the University of Florida found that spring drought followed by continual summer rainfall is critical f...

Large-scale genomics project will hunt genes behind common childhood diseases

...en. This project will help to set the standard for identifying biological links to childhood diseases." ...

Loosen up, DNA: Leukemia gene changes genetic packaging

...grow turned off. Li's paper goes one step further, identifying JAK/STAT, a known cancer-causing pathway in people, as one mechanism that has the ability to turn on sets of genes that have been silenced in this way. Scientists have thought that JAK/STAT works by directly turning on genes that make tumor cells g...

Science captures the essence of fruit

...many years, science has generally lagged behind in identifying which genes are needed to produce the desired outcome. HortResearch has now overcome this issue by using research initially intended to speed up the process of fruit breeding, says Dr Newcomb. "Through decades of fruit breeding research HortResearc...

Diabetes hits 275 Australians each day as pandemic spreads

...tudy. IDI researchers established a world-first by identifying a national representative sample of Australia's adult population and carrying out individual blood tests for diabetes. The Director of the International Diabetes Institute, Professor Paul Zimmet, said the research findings sent a "Red Alert" to ordi...

Coming soon: 3-D imaging that flies 'through' and 'around' cancer

... providing 3-D views of blood vessels and possibly identifying individuals at risk for heart disease," he predicted. In the case of a patient with colorectal cancer--a term used to refer to cancer that develops in the colon or rectum and is the second leading cause of cancer-related deaths in the United States...

Lost in thought: Brain research

...hey performed quick recognition exercises ?such as identifying pieces that included a trumpet's sound. The scientists were particularly interested in certain regions in the prefrontal cortex, a part of the brain known to be involved in personality and self-knowledge, among other things. Indeed, the fMRI confirme...

First-ever genomic test predicts which lung cancer patients need chemotherapy to live

... disease. Recurrent tumors are typically fatal, so identifying at-risk patients is critical to properly treating them, said the Duke researchers. "Using the unique genomic signatures from each tumor, our new test predicted with up to 90 percent accuracy which early-stage lung cancer patients would suffer a rec...

New strategy rapidly identifies cancer targets

...tein database at the National Library of Medicine, identifying each of the team's peptides as a segment of a specific protein. The analysis showed that many of the peptides came from tyrosine kinases. Scanning this list, Druker picked out five as likely suspects. Druker's team then introduced into their leuke...

New light microscope sharpens scientists' focus

...ells by imaging just a few molecules at a time and identifying each one's center ?but no one yet knew how to separate out a cell's densely packed proteins to make that possible under physiological conditions. It was a tool developed in a biology lab that ultimately inspired the two physicists plan to build a ...

Study reveals how cells destroy faulty proteins in cystic fibrosis

...Pulmonary Research and Treatment Center focused on identifying the cellular system that disposes of faulty CFTR. The investigators identified cell components that specifically recognizes misshapen CFTR and drops it in the molecular trash bin. The team found that turning off these components ?the cell's trash col...

Schepens scientists are first to discover angiogenesis switch inside blood vessel cells
