DNA lends scientists a hand, revealing new chemical reactions
...' has been mined thus far, or even what this space looks like. We were therefore intrigued by a different approach to reaction discovery that does not focus on any specific combination of substrates but instead can simultaneously examine many combinations." DNA-templated synthesis, pioneered in Liu's group...Award winning researchers reveal potential new role for Glivec
...Switzerland: Imatinib or Glivec as it also known looks as if it may become an effective treatment for yet another type of cancer. Consultant medical oncologist Dr. Grant McArthur told a news briefing today (Wednesday 29 September) that a Phase II study by an international team has shown that the drug is ...Anthrax enzyme images reveal secrets of antibiotic resistance, suggest new drug design
... to bind DHPP anyway. Either way, our new molecule looks like it could be the basis of a very effective new antibiotic against anthrax bacteria." In addition, because many other infectious bacteria use DHPS to make folate, the St. Jude study holds promise for solving the growing problem of antibiotic resi......tructurally complex, Nunnari said. A mitochondrion looks a bit like an orange -- an outer membrane, analogous to the orange peel, contains it, while a different type of membrane on the inside facilitates the mitochondria's functions. Scientists wondered how two mitochondria could join without mixing up the...DuPont introduces in-home personal protection from dangers of hurricanes

The room is ventilated and electricity and plumbing can be installed. It is ideal for both existing homes an...22nd amino acid synthesized and added to genetic code of e. coli bacteria

"Now it looks like nature has been doing the same kinds of experiments all along and has produced a never-before-seen translator protein for pyrrolysine." Following their joint discovery of L-pyrrolysine, Krzycki's colleague Michael Chan, an associate professor of...New sign language suggests children create language's fundamentals through learning
...is done in spoken language. "So what they're doing looks very language-like and does not look gesture-like, even though they're taking gestures to make the language. And that tells me there's something really core about that drive," Senghas said.

TANGO thus opens possibilities for new diagnostic techniques for diseases...Images of 'tail' of protein needed for cell multiplication suggest anticancer drug targets
...though most of the E2 that binds with E1 and NEDD8 looks like any other E2, its tail makes this enzyme unique." The tail of the E2 that binds to NEDD8 and the way the tail holds E2 onto E1 give this workshop a different shape than the ones in the ubiquitin pathway. The slight modification in shape limits t...Hunting illusive signs of natural selection
...nges that are visible in our genetic makeup if one looks very carefully, according to a team of biologists and anthropologists.

This [greenhouse] project is the first fruit of that idea." Says Jessica Turnle...Essential smell gene may provide key to new insect repellents
... for smell receptors, all of them have a gene that looks like the fruit fly Or83b gene. Solving an old mystery The ubiquitous Or83b gene has perplexed scientists since 1994, when Vosshall and her colleague Hubert Amrein, now at Duke University Medical Center, first identified it in fruit flies while they...Humans march to a faster genetic 'drummer' than primates, UC Riverside research says
...ns and primates march to the rhythm of a drum that looks identical; the same size, shape and sound. But, the human drum beats faster." This chemical analysis of DNA structures also showed something else. The spread of the Alu DNA repeats was written into the chemistry of human chromosomes. The process was...Advances in tumor angiogenesis Dendritic cells co-opted to the dark side
