Wine grape genome decoded, flavor genes found

While the findings will do nothing to enhance the mystique of winemaking, they could pave the way for gene-based manipulations to boost flavor and improve resistance against disease.

Study Finds Virus Contributes to Obesity

New research announced Monday found that when human stem cells _ the blank slate of the cell world _ were exposed to a common virus they turned into fat cells. They didn't just change, they stored fat, too.

Artificial life likely in 3 to 10 years

"It's going to be a big deal and everybody's going to know about it," said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. "We're talking about a technology that could change our world in pretty fundamental ways - in fact, in ways that are impossible to predict."
That first cell of synthetic life - made from the basic chemicals in DNA - may not seem like much to non-scientists. For one thing, you'll have to look in a microscope to see it.
"Creating protocells has the potential to shed new light on our place in the universe," Bedau said. "This will remove one of the few fundamental mysteries about creation in the universe and our role."
And several scientists believe man-made life forms will one day offer the potential for solving a variety of problems, from fighting diseases to locking up greenhouse gases to eating toxic waste.
Bedau figures there are three major hurdles to creating synthetic life:
- A container, or membrane, for the cell to keep bad molecules out, allow good ones, and the ability to multiply.
- A genetic system that controls the functions of the cell, enabling it to reproduce and mutate in response to environmental changes.
- A metabolism that extracts raw materials from the environment as food and then changes it into energy.

Inflammation, Angiogenesis And Breast Cancer Linked In Chain Of Events

A well-known inflammatory protein spawns an enzyme that inactivates two tumor-suppressing genes, ultimately triggering production of new blood vessels to nourish breast cancer cells, researchers at The University of Texas M. D. Anderson Cancer Center report in the August edition of the journal Cell. "This is a completely new pathway for inflammation-induced cancer and may provide new targets for clinical intervention," senior author Mien-Chie Hung, Ph.D., professor and chair of M. D. Anderson's Department of Molecular and Cellular Oncology says of the chain of events described in the journal. Hung and colleagues showed that IKKa phosphorylates CBP in the nucleus, switching CBP's binding preference to the NF"B oncogene, promoting cell growth. Unphosphorylated CBP helps p53 do its job suppressing cancer by forcing defective cells to kill themselves, programmed cell death known as apoptosis.

Amgen cutting costs as key anemia drug sales fall

Amgen's Epogen and its newer and longer-lasting Aranesp were the top revenue producing biotech drugs in the United States last year, respectively reaping sales of $2.5 billion and $4.1 billion, funded in large part by government health programs in the United States and abroad. This year is a different story. Anemia drug revenue at Amgen has dipped 10 percent in the first half and the company's shares have shed nearly 27 percent of their value as safety and overuse concerns fuel reimbursement cutbacks by the agency that runs government health programs for elderly, disabled and poor Americans.
