Bacterial genome sheds light on synthesizing cancer-fighting compounds

... are breathing a sigh of relief, as they no longer run the risk of being harvested for their natural disease-fighting substances. Scientists recently discovered that the bacterium Prochloron didemnii, which lives symbiotically inside the sea squirt, actually produces the desired patellamides, compounds t...

It's electric: Cows show promise as powerplants

Motor transport in bio-nano systems

...these collisions, the molecular motor has a finite run length: After a few seconds, it unbinds from its track and performs random Brownian motion in the surrounding water until it rebinds to the same or another filament. In order to understand the motor traffic in biological cells and in biomimetic syst...

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

Drawing with DNA: 'Bioart' illuminates genomics

..., tens of thousands of biologists around the globe run DNA sequences of unknown function through a lightning-fast online algorithm called BLAST ?typically submitting 200 to 400 base pairs, or "letters" of genetic code, to be matched against the billions of letters for known genes. Searching for similarit...

UNC computer, marine scientists collaborate to predict flow of toxic waters from Katrina

... State that is based on the Chapel Hill campus and run by Reed. RENCI is slated to receive $11.8 million in recurring funding thereafter. "If we had a month to do these runs, we could do them on our desktop computers or on a small cluster, but to do it literally overnight requires some horsepower," Blan...

Penguin chicks exposed to human visitors experience spike in stress hormone

...ourists don't go, they're much more skittish. They run away or dive into their nests," he said. The research was conducted at a penguin reserve at Punta Tombo, Argentina, with three separate sampling periods in November and December 2001 and January 2002. Chicks aged 6 to 7 days were captured and blood ...

Defect in gene causes 'neuralgic amyotrophy'

...isposition, carriers of the hereditary form of HNA run greater risk of having an attack. Its re-occurrence, and the fact that the disease is provoked by environmental factors, make this disorder unique in the group of peripheral nervous system disorders. Therefore, HNA is a genetic model for more frequen...

Otter adaptations: How do otters remain sleek and warm

The research findings are published in the journal Physiological and Biochemical Zoology (Vol. 78, 3, May/June 2005) by Michael Kearney, Rebecca Wahl and Kellar Autumn. "This is extraordi...

Nanoscale method for investigating living systems

...tum dots formed their own pores, which in the long run could mean that we could combine optical activity and readout with direct-current recording of cellular activity," says Blick. Because these artificial pores elicit bursts of current in the artificial membranes, the team believes quantum dots could p...

Scientists create digital bacteria to forge advances in biomedical research

Emonet is the lead author of a paper announcing the development of AgentCell that was published in the June 1 issue of the semimonthly journal Bioinformatics. His c...

Birds and bats sow tropical seeds

And he predicts close academic collaboration between UNAM and U.S. ecology programs like UIC's. "It will involve environmental issues which will occupy a great many students," he said....

Experimental shingles vaccine proves effective in nationwide study

...t causes chickenpox. Once chickenpox infection has run its course, the virus is not eliminated; rather, it retreats to clusters of sensory nerve cells usually located near the spinal cord, where the virus persists in a dormant state. As immunity weakens with advancing age, the virus can reactivate, multi...
