Transgenic trees hold promise for pulp and paper industries

...the lab rats of forestry research." The scientists scratch the leaves and expose the wound to bacteria carrying the beneficial genes. Treated leaf-disks, with their enhanced genomic structure, are then cloned, producing trees with predictable qualities. As with any research involving genetic engineering, Chi...

...sides to prevent erosion. "In neighborhoods, they scratch the paint on cars, damage shinglesand tiles on roofs and cover lawns with fecal matter. When a man inPalos Verdes Estates stepped between an attacking peacock and a childon a tricycle, the bird ripped open the man's pants with its spurs.Another bird'...

Yeast, wormwood & bacterial genes combine in microbial factory to make antimalarial drug

...nsive for the chemical industry to synthesize from scratch and nearly as expensive to extract from plant material. "This process could be of interest to everybody -- drug companies making cancer agents, the government producing antibiotics against bioterror agents, or industries making flavors and fragrances...

160,000-year-old fossilized skulls from Ethiopia are oldest modern humans

...ut apparently did not polish or decorate them with scratch marks. Modifications like those seen in the Herto skulls have been recorded by anthropologists from societies, including some in New Guinea, in which the skulls of ancestors are preserved and worshipped.

UCSD scientists develop novel way to screen molecules

...ad by a CD player." While usually anything, like a scratch on the CD surface, that would interfere with the detection of the bits of information encoded on a CD would be a drawback, the UCSD researchers actually exploited this error to detect molecules. "That's the novelty of this," Burkart points out. "We...

Genetic differences revealed by SNPS play a role in risk, prevention and outcome for cancer

...eck cautioned that scientists are just starting to scratch the surface of what's possible for the prevention, diagnosis and treatment of cancer, with the help of SNPs and haplotypes.

Microbe's trick provides a template for willowy crystals

...bone, things that have never before been made from scratch by human hands. "The hope is that this may inspire new routes for biomimetic synthesis," Banfield says. De Stasio notes that mollusks, combining a polymer matrix and a mineral, produce shells that are 3,000 times harder than the mineral alone. Scient...

Chemical reaction in birds provides sense of direction during migratory flights

...eter. When the birds moved in the cages, they left scratch marks that were counted subsequently by the researchers and analyzed. To produce artificial oscillating fields, the researchers fed high-frequency currents from a signal generator into a coil that surrounded four test cages. The coil, with a diamete...

Promising hospital anti-infection strategy probably won't work, study shows

...tic is introduced and the pathogen must start from scratch in building resistance. However, the model implies that pathogens actually encounter new antibiotics more frequently when hospitals use antibiotic mixing than when they use cycling, so cycling is unlikely to reduce resistance levels. "If the cyc...
