Plants, too, have ways to manage freeloaders

... D. Lee Taylor, a former UC Berkeley post-doctoral fellow now at the Institute of Arctic Biology in Fairbanks, Ala., current UC Berkeley graduate student Joshua Povich, and Richard P. Shefferson, now of the Forestry and Forest Products Research Institute in Tsukuba, Japan, reported their findings in October...

Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

...xplains first author Syee Weldeab, a post-doctoral fellow in the Department of Earth Science at the University of California, Santa Barbara. The monsoons are critical to sustaining agriculture in equatorial Africa. Weldeab says that man's reduction of inland vegetation cover through deforestation and overg...

Researchers unlock how cells determine their functions

...Institut für Molekulare Immunologie in Munich, and fellow UCR researchers Tilman Sanchez-Elsner and Dawei Gou authored the paper titled, Noncoding RNAs of Trithorax Response Elements Recruit Drosophila Ash1 to Ultrabithorax. The paper explains how proteins, known as epigenetic activators (such as Ash1 from...

A biosensor layered like lasagna

.... Lin and co-author Guodong Liu, a postdoctoral fellow in Lin's group, coaxed electrostatic clinginess in a polymer and an oppositely charged protein-enzyme, in this case glucose oxidase, which reacts in the presence of blood sugar. The catalyzed products from the reaction ping the carbon nanotube; if t...

Liver cancer linked to cellular repair pathway

... tissue, said Jason Sicklick, M.D., a postdoctoral fellow at Duke and lead author of the study. "Currently, there are no good chemotherapies for liver cancer, and many people with advanced liver disease are too ill for surgery to remove tumors," Sicklick said. "There is a desperate need for effective antic...

Neurons find their place in the developing nervous system with the help of a sticky molecule

... and Akihide Takeuchi, M.D., Ph.D., a postdoctoral fellow and the study's first author, tested this hypothesis. They first showed that layer 2/3 neurons make MDGA1 protein as they migrate to their destination. Then, utilizing a cutting-edge molecular technique called RNA interference, the Salk researchers s...

Pitt professor's theory of evolution gets boost from cell research

Growth hormone is made in the brain, report scientists

...stine P. Donahue. Donahue, formerly a postdoctoral fellow of Ken Kosik, is an instructor in the Department of Neurology at Harvard Medical School. The authors suggest that because growth hormone in the body is associated with growth of the body, it may also cause growth in the brain. Females have more dend...

'Bad' enzymes may wear white hats after stroke

...rd Hughes Medical Institute (HHMI) medical student fellow at Harvard Medical School, is second author of the article. She was deeply involved with the study's data analysis, and established a way to quantify the response of proteins involved in the cell growth and blood vessel remodeling that occurs after s...

'Uniquely human' component of language found in gregarious birds

...pert on starlings and, at the time, a postdoctoral fellow at the University of Chicago, was an essential addition. To assess the birds' syntactical skills, the research team exploited the diverse sounds in starling songs. They recorded eight different 'rattles' and eight 'warbles' from a single male starl...

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

... Wolf, M.D., Ph.D., Duke Medical Center cardiology fellow and first author of paper appearing Jan. 23, 2006, in the Early Edition of the Proceedings of 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 ...

Immune system response to viral DNA is unique

...uses, according to Daniel Stetson, a post doctoral fellow in the Section of Immunobiology and lead author of the study. Although there are countless types of viruses, they can all be placed in two categories based on the type of nucleic acids that comprise their genome: viruses made of RNA and viruses made...

'Executive' monkeys influenced by other executives, not subordinates

Attention shoppers: Researchers find neurons that encode the value of different goods

...m," says Camillo Padoa-Schioppa, PhD, HMS research fellow in neurobiology and lead author of the paper. "The neurons we have identified encode the value individuals assign to the available items when they make choices based on subjective preferences, a behavior called 'economic choice.'" Everyday examples ...

UCSD biologists find new evidence for one-way evolution

...graduate student at UCSD and is now a postdoctoral fellow at Cornell University. While lending support to the question of unidirectional evolution, the biologists' findings also lead to new questions. "Apparently, plants that have sex exclusively with other plants and not themselves, enjoy a greater evol...
