...king at it." Warkentin examined the recordings to see whether she could tell how rain and snake-attack vibrations differed. "Two of the most obvious differences between vibrations caused by rain and vibrations caused by snakes are elements of the temporal pattern," she says. "Snake bites, in general, la...

Scientists take aim at virulent bacteria by decoding machinery of key control enzyme

...ng the 3-D crystal structure, we have been able to see the specific Dam structure in action, including the way it binds to the DNA and moves along the base pairs as it recognizes and methylates the A nucleotides," says Dr. Cheng. "Using this information we can potentially design a drug to inhibit this pa...

...compartments, which resemble axons of nerve cells, see Figure 2, and radial arrangements of filaments within disk-like compartments, which resemble large cells adhering to a substrate surface. Surprisingly, the geometry of the system has a rather strong effect on the build-up of traffic jams. In uniaxia...

Study shows humans have ability to track odors, much like bloodhounds

...inside a functional MRI to allow the scientists to see which areas of the brain were most active during sniffing and attempts to identify and localize odors. They found that the left and right nostrils have separate areas of the primary olfactory cortex - the brain's smell center - devoted to them, indic...

Researchers use 3-D imaging system to unveil swimming behavior of microscopic plankton

...g aspects of this research is that we were able to see 375,000 of these animals, many as small as one millimeter in length," said Jaffe, a research oceanographer in the Marine Physical Laboratory at Scripps. "I find it fascinating and remarkable that we can capture the reflection of such tiny creatures i...

Anthrax test, developed by army and CDC, receives FDA approval

...ted with suspicious anthrax colony growth, you can see clear zones where the B. anthracis cells have been destroyed--whereas other bacterial cells grow unaffected." Well before the anthrax attacks of 2001, scientists at USAMRIID and the CDC recognized the need for an FDA accepted method for identifying ...

Scripps research scientists solve structure of a critical innate immune system protein

...gy. "All of us in the TLR field have been dying to see the structure of a TLR ectodomain since the innate immune function of TLRs was discovered seven years ago. This will open the way to a great many other studies that will allow us to understand exactly how signaling occurs." Significantly, says Wilso...

Study: Harmless virus kills some cancers

...lowed the AAV2 to remain in culture long enough to see the effect that Meyers and his team observed. "One of the most compelling findings is that AAV2 appears to have no pathologic effects on healthy cells," Meyers said. "So many cancer therapies are as poisonous to healthy cells as they are to cancer c...

Major advance made on DNA structure

..."Now, for the first time, we're really starting to see what the genome looks like in three dimensional reality, not just what the sequence of genes is," Ho said. "DNA is much more than just a string of letters, it's an actual structure that we have to explore if we ever hope to understand biological func...
