New book expands biological classifications to account for 'alien' life

...gy and oceanography, to prepare themselves for the search for life away from Earth. Ward also was a co-author, with UW astronomer Donald Brownlee, of a popular book called "Rare Earth," published in 2000. The book advanced the idea that simple microbial life might be very common in the universe but complex...

UT Southwestern researchers discover master switch in cell death

...-1 will degrade tremendously,?Dr. Zhong said. The search for Mule took more than two years, as the UT Southwestern researchers specifically searched for an enzyme that controls Mcl-1. The interaction between Mule and Mcl-1 might someday be manipulated to help cancer patients, Dr. Wang said. For instance, ...

Neurotransmitters signal aggressive cancer, offer potential for early diagnosis

...nd the revolution in medicine to be a DNA-centered search for mutations in genes that cause disease. This study illustrates another layer of the revolution - understanding how certain diseases, in this case cancer, are linked to abnormalities in cellular metabolism - an area called 'metabolomics'. We've des...

New tooth enamel dating technique could help identify disaster victims

...already have used enamel dating to help narrow the search for victims of last December's tsunami in Southeas... (MIR) technology also is being deployed to assist search and rescue crews in locating hurricane victims. This same technology was deployed in the days follow...

New gene scanning technology marks a major advance in disease research

...chool of Medicine has been successfully applied to search for rare genetic mutations in the population at large. Their method, called meltMADGE, which combines thermal ramp electrophoresis with microplate array diagonal gel electrophoresis (MADGE), enables significantly higher levels of scanning at a fract...

Virus uses tiny RNA to evade the immune system

... postdoctoral fellow in Ganem's lab, started their search for viral microRNAs with a small virus, known as SV40, in the belief that its diminutive size would make it easier to understand the functions of any microRNAs they found. SV40 is a relatively harmless monkey virus that can cause kidney infections i...

New technique could alter field of mouse genetics

...ed in human biology and disease and accelerate the search for effective new therapies. The researchers report their study in the August 12, 2005, issue of the journal Cell. Certain genes or genetic elements, called transposons, can hop from one place to another in the genomes of various organisms. In peopl...

Scientists create digital bacteria to forge advances in biomedical research

...ipped with all the virtual components necessary to search for food. These digital E. coli contain their own chemotaxis system, which transmits the biochemical signals responsible for cellular locomotion. They also have flagella, the whiplike appendages that cells use for propulsion, and the motors to drive ...

Computers close in on protein structure prediction

Evolution of life on Earth may hold key to finding life in outer space

...sults of this type of research also help guide the search for life elsewhere in the universe, which is an important NASA objective." The goal of Fox's grant ?"The Origins of Translation and Early Evolution of Life" ?is to understand when and how the ribosome (or cellular protein synthesis machinery) came i...

Gradient guides nerve growth down spinal cord

...e cells send out axons, long narrow processes that search out and connect with other nerve cells. Axons are tipped with growth cones, bearing specific receptors, which detect chemical signals and then grow toward or away from the source. In 2003, University of Chicago researchers reported that a gradient o...

Researchers find how some antibiotics kill bacteria

...ive to another. "That may help to narrow down the search for new synthetic derivatives to conquer resistance altogether." The study appears in the current issue of the journal Cell. Ryfamycin antibiotics are one of the first-line treatments for tuberculosis, a disease that is on the rise worldwide. The d...

Virtual animal shelters ?How the Internet is transforming the experience of pet adoptions

...new addition to the family. And, the Internet dog search shuts out the noise and the smells associated with a county shelter. However, Garcia adds that the drawbacks are that pet postings are not interactive, and chemistry between the dog and its new owner is a vital part of the selection process. Garcia'...

From a Few Wild Ancestors, a Citrus Cornucopia

...sity in the Citrus genome. This makes it easier to search for specific genes related to pest and pathogen resistance and to high flavonoid and nutrient levels.?/p> For their work, the researchers used 25 molecular markers, 13 of which they created, to help them track genetic similarities between accessi...

Huntington's cure in flies lays groundwork for broader treatment approaches

...ue for directing research dollars to the continued search for epilepsy genes, Yin believes funding agencies should now consider investing in the search for these "superhighways" of gene convergence. That search might be long and tedious, he adds, but ...

'Underground' tunnels discovered as means for communication between immune system cells

...ing only those cells that discharged. A literature search turned up a handful of papers describing tunneling nanotubules, and further imaging using the highest magnification possible disclosed their presence in both the dendritic cells and macrophages. In their most definitive experiment, the researchers p...
