Why species matter

UC Santa Barbara doctoral candidate Caitlin Fong travels to French Polynesia often but not for vacation. She goes there to study a coral reef ecosystem influenced by human impacts such as overfishing and nutrient pollution. Her work focuses not only on biological changes but also methods scientists use to determine within-group group responses to ecological processes. The findings are published in ESA Ecology, a journal of the Ecological Society of America. Fong and Peggy Fong, a professor in UCLA's Department of Ecology and Evolutionary Biology, conducted a study assessing ...

Not so fast -- our fishy friends can also feel pain

Do you still believe that fish are dumb and cannot feel pain? That we do not have to worry much about how they are cared for or caught? Think again, says Culum Brown of Macquarie University in Australia, in a review article in Springer's journal Animal Cognition. The research notes that fish cognition and their sensory perception are generally on par with that of other animals. Brown therefore argues that more consideration should be given to fish welfare and anti-cruelty issues. The Australian researcher says that most people rarely think about fish other than as food, ...

Heparin derivative suppresses neuroblastoma tumor growth

DURHAM, N.C. -- Researchers at Duke Medicine have identified a new strategy for treating neuroblastoma using a modified version of heparin, a century-old injectable drug that thins the blood to prevent clots from forming. The study, conducted in mice and published June 17, 2014, in the Journal of Clinical Investigation, found that when heparin is altered to remove its blood-thinning properties, it can suppress and shrink neuroblastoma tumors without causing severe bleeding. "Our research translates mechanistic insights about heparin into a potential new therapy for ...

Urban Water Management Workshop stresses more collaboration and innovation

RIVERSIDE, Calif. — Where sustainability of water management is concerned, we must pay more attention to long-term solutions. Efficient water management and policy ought to be promoted at the local level. And a "portfolio approach" to water management is encouraged, one that includes information campaigns, different types of pricing, supply and reuse options, and technology-based rebate programs. These are some of the key messages that emerged from the first Urban Water Management Workshop that took place earlier this month at the University of California, Riverside. Sponsored ...

Ultra-thin wires for quantum computing

WASHINGTON D.C., June 17, 2014 - Take a fine strand of silica fiber, attach it at each end to a slow-turning motor, gently torture it over an unflickering flame until it just about reaches its melting point and then pull it apart. The middle will thin out like a piece of taffy until it is less than half a micron across -- about 200 times thinner than a human hair. That, according to researchers at the Joint Quantum Institute at the University of Maryland, is how you fabricate ultrahigh transmission optical nanofibers, a potential component for future quantum information ...

Researchers map genomic differences in yellow fever, malaria mosquitoes

Virginia Tech entomologists have developed a chromosome map for about half of the genome of the mosquito Aedes agypti, the major carrier of dengue fever and yellow fever. With the map, researchers can compare the chromosome organization and evolution between this mosquito and the major carrier of malaria, the Anopheles gambiae mosquito, to find ways to prevent diseases. "Despite looking somewhat similar, these mosquitoes diverged from each other about 150 million years ago. So, they are genetically further apart than humans and elephants," said Maria Sharakhova, a ...

Pain pilot explores hand shiatsu treatment as sleep aid

(Edmonton) There was a time, back in Nancy Cheyne's youth, when she combined the poise and grace of a ballerina with the daring and grit of a barrel racer. When she wasn't pursuing either of those pastimes, she bred sheepdogs, often spending hours on her feet grooming her furry friends at dog shows. All that seems like a lifetime ago. After 15 years of living with chronic lower-back pain, Cheyne, 64, can't walk from the disabled parking stall to the elevator at work without stopping for a rest. She eats mostly junk food because it hurts too much to stand over the stove ...

Boost for dopamine packaging protects brain in Parkinson's model

Researchers from Emory's Rollins School of Public Health discovered that an increase in the protein that helps store dopamine, a critical brain chemical, led to enhanced dopamine neurotransmission and protection from a Parkinson's disease-related neurotoxin in mice. Dopamine and related neurotransmitters are stored in small storage packages called vesicles by the vesicular monoamine transporter (VMAT2). When released from these packages dopamine can help regulate movement, pleasure, and emotional response. Low dopamine levels are associated with neurodegenerative diseases ...

Gut bacteria predict survival after stem cell transplant, study shows

(WASHINGTON, June 17, 2014) – New research, published online today in Blood, the Journal of the American Society of Hematology, suggests that the diversity of bacteria in the gastrointestinal tract of patients receiving stem cell transplants may be an important predictor of their post-transplant survival. A healthy gastrointestinal tract contains a balanced community of microorganisms (known as microbiota), largely comprised of "friendly" bacteria that aid digestion and are important to immune system function. When this community of microbes is compromised, the microbiota ...

Crowdsourcing the phase problem

Compared with humans, computers have the capacity to solve problems at much greater speed. There are many problems, however, where computational speed alone is insufficient to find a correct or optimal solution, for example because the parameter "space" cannot be fully searched in a practical time. In contrast, the human mind can formulate expert knowledge specific for particular problems, providing a capacity to guide more efficient searches, although with more limited processing speed. The power of the human contribution can be multiplied through the efforts of a greater ...
