Draft Fugu genome will help find human genes.
A draft sequence of the puffer-fish genome is complete. The fishs compact genetics should accelerate the discovery of human genes and their key controlling sequences.
Gene-prediction programs struggle to find genes in the 3 billion letters of the human sequence, which includes swathes of junk DNA and defunct pseudogenes.
The bony fish Fugu rubripes shares our gene repertoire but has a genome one-eighth of the size.
Paying attention isn’t the only way to learn.
You must pay attention to learn, teachers say. Not necessarily, US psychologists now argue: sights we are unaware of can have a lasting impact on our brains.
Subliminal training can improve our ability to see moving dots, Takeo Watanabe and his co-workers at Boston University, Massachusetts, have found. “Without noticing, we are unconsciously learning,” Watanabe says. Repeated exposure to objects we are oblivious to “could have
Ancient embalming not to be sniffed at.
Archaeologists thought they had mummification wrapped up. But a new analysis of ancient Egyptian embalming suggests that they have underestimated this sophisticated funerary practice.
Pharaonic undertakers used a wealth of oils, waxes and fats, say Stephen Buckley and Richard Evershed at the University of Bristol, UK. They are the first to study several mummies from different periods using modern analytical chemistry 1
Bugs behind typhoid and food poisoning give up genetic secrets.
Two teams have sequenced the genomes of two Salmonella bacteria. One is responsible for typhoid; the other causes food poisoning.
The genomes should lead to new ways to diagnose, treat and vaccinate against both diseases. Comparing the sequences should also clarify why the closely related bugs behave quite differently.
The two strains are called Typhi and Typhimurium. Typhi, the typhoid bug, infects onl
Recent events have confirmed that bioterrorism is no longer a threat but a reality. To provide wide-ranging access to the latest scientific information about anthrax and other potential bioweapons, Nature has put together a special online focus on this issue. This focus includes the pre-publication* of two research papers on anthrax toxin, as well as a collection of research, news and feature articles from our electronic archive. Because of the heightened interest in this area, among both the scient
Genetic engineering gives us the fluorescent daisy.
It’s produced in Italy and guaranteed to make the face of that special someone light up. It’s the luminous bouquet. Under ultraviolet light the apparently normal blooms glow an unearthly green.
“The fluorescent flowers show that genetic engineering can be developed just for beauty,” says their developer, Tito Schiva of the Experimental Institute of Floriculture, San Remo. The technique should work for any white flower, Sch
