Scaled-down genome may power up E. coli's ability in lab, industry

...t fly has a very specific shape and a beetle looks quite different. We thought it would be a good place to start, since they also develop very differently. "Once the genes involved in segmentation were identified in other insects, we asked if they function the same as in fruit flies. If the function of th...

UF scientists reveal ancient origin of vertebrate skeleton

...ny fishes, while the lamprey skeleton was based on quite different proteins," said Martin Cohn, Ph.D., a developmental biologist and associate professor with the UF departments of zoology and anatomy and cell biology. "Knowing that lampreys also use collagen to build their skeletons makes sense. Lampreys a...

Computers to save unique type of American red squirrel

...hipmunks, voles, and mice, and the forest would be quite different without these animals. Moreover, if we can't save a species in a relatively controlled, isolated environment like this, it doesn't bode well for effective conservation of other species in more complex situations." ...

Carnegie Mellon scientists show brain uses optimal code for sound

...tural way via our discovered coding, then we could quite possibly design implants that would convey sounds to the brain that are much more intelligible," he said. ...

Canine cancer vaccine program shows early promise

...s oncology section. "But those that do seem to do quite well." She would like to continue working on the vaccine in the hope that this innovative anti-cancer strategy will translate into similar novel treatments in people with cancer. Melanoma, the equivalent of one form of skin cancer in humans, is ve...

Tiny polyps gorge themselves to survive coral bleaching

...iness of coral reefs, the creatures themselves are quite fragile. These tropical organisms survive in a narrow 4-to-6-degree C temperature range centered about 26 degrees C. While the exact temperatures vary with individual species from location to location throughout the tropics, they all must live within...

Gene needed for butterfly transformation also key for insects like grasshoppers

...ature such as a caterpillar changes into something quite different, a butterfly. Contrast that with a grasshopper, which looks largely the same from the time it hatches through its adult stage. New University of Washington research shows that a regulatory gene named broad, known to be necessary for devel...

Fruit fly's beating heart helps identify human heart disease genes

...f the National Academy of Sciences. "This can be a quite a complex and laborious undertaking. Even in mouse models of human disease, the process of screening for genes can take a long time. "However, fruit flies, with their well-documented genome and rapid life-cycle, have the potential to greatly speed t...

Chemotherapy gel may fight breast cancer and reduce breast deformity

... that also would fill in the dimples and sometimes quite significant indentations that are common after breast surgery and radiation." To test their idea, the researchers encapsulated a common breast cancer chemotherapy drug, doxorubicin, in microspheres, or beads, and then mixed them with a gelatin made ...

Male rivalry increases when females at most fertile, say researchers

..."'Groups of animals, such as chimpanzees, can live quite happily together, but when a female is ready to mate the two dominant males within the group become rivals and fight for her attention. Similarly in humans, rated dominance increases when the female is most fertile. What is interesting here is that...

MIT: Oceans are a major gene swap-meet for plankton

...trains "are very closely related, yet they display quite an array of physiologies, and astounding genetic diversity on top of that," Chisholm said. It's becoming clear, too, that "this genetic diversity is at the heart of the extraordinary stability of Prochlorococcus in the oceans, which maintains steady ...

Unique equine cataract surgery offered on routine basis

...hted with the outcome of TC's surgery. Surgery is quite rarely performed in the UK on horses with cataracts as it carries risks but if I had not agreed to this pioneering operation the only other course of action would have been to have my horse put down. "As a showjumping horse, it was vital to have...

Mobile phone use not linked to increased risk of glioma brain tumours

...king the number of long term users (over 10 years) quite small. This study had limited numbers for estimating the risk of using a phone over a long period. Early mobile phones were designed to use analogue signals and emitted higher power than current digital phones but the study showed no increased risk ...

New nano-canary in the nanotoxicology coalmine: The body itself

...e that these incredibly small materials can behave quite differently from conventional materials. Nonetheless, neighborhood stores feature products that promise benefits from these near-atomic level materials, from paints and cosmetics to toothpaste and sunscreens. But, could we be putting human health a...

Warming trend may contribute to malaria's rise

...said. "And because mosquito abundance is generally quite low in these highland regions, any increase in abundance can be an important factor in transmission of the disease." In the current study, the researchers looked only at the link between temperature and mosquito abundance, not at malaria statistics...

Gene patterns in white blood cells quickly diagnose disease

... very specific changes in gene expression that are quite unique to each pathogen as little as 2 hours after exposure. Use of mathematical modeling tools has identified a list of over 300 genes that can discriminate among 8 pathogenic agents with 99 percent accuracy," says Hammamieh. They are also looking...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...ptIPuter and CAMERA projects. "The architecture is quite general and will be quickly adaptable to other areas of data-intensive science." Collaboratories are virtual laboratories where scientists can collaborate on research from dispersed locations--interacting with colleagues, accessing instrumentation, ...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

... ability and cell renewal throughout life. Until quite recently, it was generally believed that each individual is born with a fixed number of nerve cells in the brain, and that these cells gradually degenerate and die during the person's lifetime and cannot be replaced. This theory was disproved when re...

Watching the brain switch off 'self'

...y processing or self-reflective introspection were quite distinct and segregated. Sensory processing activated the sensory cortex and related structures, while introspection activated the prefrontal cortex, they found. Importantly, the researchers found that activity in the self-related prefrontal cortex ...
