Divergent life history shapes gene expression in brains of salmon

...enes demonstrating differing activity levels. "It makes sense that growth genes are suppressed in sneakers and genes associated with reproduction are expressed more, since these fish essentially trade bodily size for faster reproductive maturity," she says. "However, it was unexpected, for instance, that ...

Millennium Ecosystem Assessment: Many of 2 billion dryland dwellers at risk as land degrades

...ucture. "The cross boundary nature of the problem makes desertification a global concern ?one that receives too little attention," says co-author Zafar Adeel, Assistant Director of the United Nations University water academy in Canada, the UNU International Network on Water, Environment and Health.

Engineered bug makes key chemical precursor from grain sorghum Trials ...cinate technology is a mutant form of E. coli that makes succinate as it's only metabolic byproduct. The bug contains more than a half-dozen genetic modifica...

A novel virus for croup

...international, open-access journal PLoS Medicine makes the strongest association yet between a newly identified virus and the pediatric respiratory disease commonly known as croup. Following their recent description of the coronavirus HCoV-NL63, Lia van der Hoek and colleagues suggest this is one of the ...

New lead reported in tumor angiogenesis

...urface of endothelial cells. "I thought, 'Oh, this makes sense,'" said Wang. "The jagged1 protein is not secreted but is displayed on the surface of the tumor cells. I speculated that HGF induced jagged1 levels to increase, leading to a direct surface to surface interaction between the tumor and endothelia...

Compound from Chinese medicine shows promise in head and neck cancer

...ed Bcl-xL that's overexpressed in cancer cells and makes these cells survive when they shouldn't. Shaomeng Wang, Ph.D., co-director of the Molecular Therapeutics Program at the U-M Comprehensive Cancer Center, discovered (-)-gossypol, a compound derived from a component of Chinese medicine. Gossypol comes...

Secrets to antibody's success against West Nile Virus surprise scientists

New technique rapidly detects illness-causing bacteria

...es of the DNA. Duplicating or "amplifying" the DNA makes a pathogen easier to detect. The new process starts with genetic material that is extracted from a food sample. This material, called ribosomal RNA (rRNA), is responsible for translating genetic information carried in DNA into proteins. Nugen desig...
