Modeling the restless brain

...ever-changing patterns. Sporns and Honey's work on modeling this brain activity sheds new light on how and when these mysterious fluctuations occur and offers insights into what the brain does while idle. "Some people see the brain in terms of inputs and outputs, like a computer. If you provide an input, y...

Australian wins prestigious prize in biodiversity informatics

... Paul Flemons applies computer-based ecological modeling to help identify places where lots of species occur together, or species that occur only in very restricted geographical areas. This helps biodiversity scientists be more efficient in their efforts to discover and conserve species. The GBIF Scie...

Definitive evidence found of a swimming dinosaur

...eas of research," said Costeur. "New biomechanical modeling will increase our understanding of dinosaur physiology and physical capabilities, as well as our view of the ecological niches in which they lived." ...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

...ntually be used as an even more general anatomical modeling tool for the biomedical community to help patients with respiratory and cardiac diseases. At the same time, Xu will continue to work on the 3-D VIP-Man to create a "family" of virtual patients, ranging in ages and sizes, in collaboration with researc...

Ecology in an era of globalization

In "The future of production systems in a globalized world," Elena Bennett (McGill University, Montreal, Canada) and Patricia Balvanera (Universidad Nacional Autónoma de Me...

US control strategies may make flu epidemics worse, UCLA study shows

...n Blower's research group, used novel mathematical modeling techniques to predict that current health policy ?based on voluntary vaccinations ?is not adequate to control severe flu epidemics and pandemics unless vaccination programs offer incentives to individuals. According to the researchers, the severit...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...esoundmanagement.com ) will present a computerized modeling tool that allows architects and acoustical consultants to maximize speech privacy in open-office spaces while minimizing the cost and complications of implementing their design. In a map of a simulated open-office plan, the tool graphically displays...

MIT's ocean model captures diversity of underwater forests

...e new model remedies that. "Now we are finally modeling the ocean systems in a way that is consistent with how biologists think of them-water filled with millions of diverse microbes that wax and wane in relative abundance through interactions with each other, and the environment, as dictated by natural s...

MIT model helps researchers 'see' brain development

...rform this alignment. The second step involves modeling the folds of the brain mathematically in a way that allows the researchers to analyze their changes over time and space. The original brain scan is then represented computationally with points. Charting each baby's brain requires about 130,000 po...

Scientists uncover link between ocean's chemical processes and microscopic floating plants

...raphy Program. Combining future experimental and modeling efforts will lead to a better understanding of the feedback systems between the atmosphere and ocean, believes Wingenter. "To predict future climate more accurately, it's critical that we understand the outcome of increasing ocean acidification and i...

Is there a pilot in the insect?

...t force. The researchers obtained these results by modeling the overland flight navigation of insects using experiments carried out on OCTAVE, a captive flying robot microhelicopter that can reproduce much of the mysterious natural insect behavior. Their work is published online in Current Biology, February 8...

Map predicting spread of avian flu

...clusions through a computational (or mathematical) modeling method, an approach which has already proved its worth in the analysis of infectious diseases such as the 2001 foot-and-mouth outbreak in the UK. The method can estimate the key parameters which determine the spread of highly transmissible animal dis...

Bacteria research offers hope for new vaccine against meningococci

...usceptible to infection from meningococci. In its modeling system Ann-Beth Jonsson’s research team therefore used mice that produce the human receptor that the bacteria bind to. Marking the bacteria to emit light, the scientists used cameras to monitor their activities in the living mice during the course o...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

Salmon farms kill wild fish, study shows

...ombine field surveys, experiments and mathematical modeling in one system to estimate the total impact of the farms." The primary sea lice hosts are adult salmon. Under natural conditions, the adults are far offshore when the juveniles are migrating out to sea. Fish farms put adult salmon in net pens along ...

Novel experiment documents evolution of genome in near-real time

...evolution approach. The approach combines computer modeling techniques with evolutionary design processes to optimize bacteria to perform commercially important processes. Aside from its commercial potential, experimental evolution of bacterial strains is also useful for refining the theory of evolution and ...

Ongoing collapse of coral reef shark populations

...tions. These observations, coupled with population modeling showing ongoing, rapid declines in population size in fished areas, lead the authors to conclude that reef sharks are approaching “ecological extinction”—that is, becoming so rare that they can no longer perform their natural role in the functioning ...
