Studying the chemistry of drugs in wastewater
...which significant wastewater treatment occurs) and identified
the resulting products using multiple techniques. Scientists found that the reactions are complicated and often produce several products, some unexpected. For instance, acetaminophen forms multiple products, two of which are highly toxic. All the dru...
DNA sequence controls expression of gene involved in cancer
... the ARE. From these constructs, the investigators identified
a region of 30 nucleotides outside the ARE that destabilizes bcl-2 mRNA both in the absence and in the presence of the ARE. Because the region is composed mostly of cytosine and adenine repeats, they named it the CA-repeated Region (CAR). The discov...
Endangered frogs coexist with fungus once thought fatal
...8, the fungus Batrachochytrium dendrobatidis was identified
from sick and dead frogs and, since then, several lines of laboratory based evidence have suggested that B. dendrobatidis is to blame for the dramatic frog declines. But with little information about how the disease impacts frogs in the wild, the c...

...molecular biology to problems in neurobiology. He identified
the peptide genes responsible for eliciting an innate behavior in a marine snail, and molecular analysis of these genes suggests how diverse behavioral patterns may be encoded in the genetic material and inherited from parent to offspring. ...

regulatory roles for several proteins whose functions had been previously uncharacterized. Koller received her bachelor's (1985) and master's (1986) degrees from the Hebrew University of Jerusalem, followed by a doctorate (1993) from Stanford....
Below the surface: New clues to plant signaling from the roots
... authors show that it is different from previously identified
plant hormones or signaling molecules and report evidence that it may be a novel carotenoid. ...
Marine Biological Laboratory summer investigator wins Nobel Prize in Chemistry
...with Joan Ruderman of Harvard University, he later identified
a specific ubiquitin ligating complex that "targets cyclin B for degradation at the end of mitosis"-the final phase of cell division. Today Hershko is studying that ubiquitin ligating complex in both clam eggs and cultured human cells in hopes ...
Brain circuit may permit scientists to eavesdrop on memory formation
Howard Hughes Medical Institute researchers have identified
a circuit in the brain that appears crucial in converting short-term memories into long-term memories. The circuit links the major learning-related area of the brain to another region that governs the brain's higher functions. The studies open the wa...
Botulism bug says no to nitric oxide, provides key to molecule's role in human cell signaling
...the evolutionary development of the sensor protein identified
in C. botulinum, dubbed SONO for "sensor of NO," the scientists were able to determine the three-dimensional structure of a related nitric oxide sensor in a different bacterium. That structure will provide a key to unlock answers to some questi...
UCR researchers identify key plant enzyme that defends against multiple infections
... from the University of California, Riverside have identified
one of the key enzymes that trigger programmed cell death, an important process plants undergo in fighting off bacterial, fungal or viral infections. The development holds out hope of improving crop yields, which are dependent on plants being able to...
New risks for bladder cancer identified by MIT team

three new chemical risk factors for bladder cancer...nt cancer rather than treat it." The team also identified
six chemicals in the same chemical family that do not appear to be human carcinogens. Because they a...

...and the molecular basis of the rescue, the authors identified
two important molecules implicated in signaling from the ES cells to the Id knock-out cells. These molecules are insulin-like growth factor 1 (IGF-I) and WNT5a. The former molecule is a long-range acting factor, and the latter is a short-range factor...

components of words (such as stressed syllables) and even parts of sentences that are more likely to trigger stuttering episodes, but the reasons for why this happens remain unclear. In efforts to pinpoint the causes even more precisely, Timothy Arb...
Rutgers-led research offers new clues in the genetic mysteries of maize
... as much as 22 percent of the maize genes could be identified
as being different. This was surprising, considering that other close relatives such as chimpanzees and humans differ in less than one percent of their genes. "It looks like significant evolutionary change happened in a relatively short time," sa...
