Study offers window into human behavior, brain disease

...th higher primates," he reflects. "I think it's fascinating from an evolutionary perspective that we have these new neurons that are involved in social behavior that are selectively vulnerable in the second major degenerative disorder." Notably, VENs are located in regions of the brain that are in a good p...

Nice guys do finish first in lizards' evolutionary race

...t not only works for some lizards, it also gives a fascinating peek into hard-wired altruism in evolutionary biology. Side-blotched lizards spend their year on earth looking to reproduce, and their strategies have lessons about evolution. An article in the May 9 edition of the Proceedings of the National Academ...

When the going gets tough, slime molds start synthesizing

...ollaborate on the chemical diversity found in this fascinating organism that crawls around on the forest floor. Says Noel, who is a professor in the Jack H. Skirball Center for Chemical Biology and Proteomics at Salk, "This is a wonderful example of where egos get pushed aside about who did what and instead, a...

What's shaped like a pear and has 2 genomes? Check the pond

...re in the world, can read about the genome of this fascinating organism before meeting it in the local pond. ...

Iron critical to ocean productivity, carbon uptake

...adily distinguish that difference. "It's really a fascinating process," Behrenfeld said. "When phytoplankton species make these extra pigments, they don't use them right away ?they bank them. Then when they get an infusion of iron, they just take off. They don't have to wait to begin dividing and growing. But t...

Outsmarting the smartie bug

...h of the pneumococcus and is also going to give us fascinating insights into the evolution of the amazing diversity of capsular genes that can be produced by this pathogen" Researchers are at pains to point out that current vaccines are enormously successful and vaccination plays an essential in protecting all ...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...evelopment. "Biased left-right asymmetry is both a fascinating and medically important phenomenon," said Levin. "...closer to understanding its impact on humans. This fascinating ion pump has additional roles during development that are a goldmine of novel cellular control mecha...

New study explores beetle species with two forms of females

A fascinating new study from the forthcoming issue of The American Naturalist attempts to explain the mysterious persistence of two forms of females in many diving beetle populations. Their findings have important implications for theories of sexual conflict, whic...

Sooner is better with cochlear implants, Stanford scientist shows

... a cochlear implant, the better. "I see this as a fascinating experiment that reveals the tremendous capacity for plasticity in the developing brain," said Eric Knudsen, PhD, the paper's senior author and the Edward C. and Amy H. Sewall Professor at the Stanford University School of Medicine. Most people don't...

Missing fossil link 'Dallasaurus' found

...North America." Mosasaurs, every bit as prolific, fascinating and nearly as big as some dinosaurs, are becoming more popular for paleontologists to study. Mosasaurs lived and became extinct alongside dinosaurs, but few paleontologists specialize in them. Later mosasaurs grew as large as their dinosaur brethren,...

Science's Breakthrough of the Year: Watching evolution in action

...liquid methane shape the land and participate in a fascinating hydrologic cycle. A Rich Year for Plants: Several key molecular cues behind flowering and other plant mysteries and surprises came to light in 2005. For example, plant molecular biologists pinned down the identity of a signal that initiates the seas...

Zebrafish may hold key to improved cancer research

...ome developing nations. Zebrafish, however, are a fascinating species because the fish embryos are literally transparent and can be directly observed at early developmental stages better than almost any other animal species. They had been used for years in studying everything from the immune system to cardiovas...

Living anti-HIV gel shows early promise

...ore the bacteria can be tested in people. "It is a fascinating concept," says Harold Kessler, associate director of the Infectious Diseases Section at Rush University Medical Center in Chicago, United States. "Obviously there is a great deal of work ahead, but it is certainly a novel approach that deserves furth...

A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...ogical Laboratory presents new data that support a fascinating model for genome evolution in bacteria that live inside insects. The scientists show that symbiotic bacteria have undergone exceptionally fast rates of protein evolution despite having precisely maintained their genomic architecture over long period...

Drugs from the deep blue

... chemical library," Molinski said. "They're really fascinating little jewels made by niche creatures." As well as being largely unexplored, the chemistry of these marine organisms is very different than that of land plants and animals, reflecting both a different environment and millions of years of separate ev...

Single gene is genetic switch for fly sexual behavior

...tterns like aggression. "I think it is going to be fascinating to try to figure out how a fly decides between 'love' and 'war', and what fruitless and the fruitless-expressing neurons have do to with this," he says. Ebru Demir and Barry J. Dickson: "fruitless Splicing Specifies Male Courtship Behavior in Drosop...

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

...cation is much more complicated. While it would be fascinating to see this interplay inside living tissue, detecting the tiny tubules in such a complex environment may be nearly impossible with current technology. ...

Digging in the dirt for life's biochemical foundations

...report in the June 9 issue of Nature. "The really fascinating part is the mechanism underlying the transfer process," says Maria Harrison, a plant biologist at Cornell University's Boyce Thompson Institute and an expert on fungus-facilitated movement of other soil nutrients into plant roots. "Dr. Shachar-Hill a...

One bacteria stops another on contact

... who has studied E. coli for over 20 years. "It is fascinating that bacteria have developed a system by which one cell can contact another and inhibit its growth." ...

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

... Marine Physical Laboratory at Scripps. "I find it fascinating and remarkable that we can capture the reflection of such tiny creatures in three dimensions from two meters away." The divers frequented the underwater setup to sample the animals, reorient the transducer and measure the vertical currents using var...
