Carnegie Mellon researchers identify brain regions that encode words, grammar, story
Carnegie Mellon University scientists have produced the first integrated computational model of reading, identifying which parts of the brain are responsible for such sub-processes as parsing sentences, determining the meaning of words and understanding relationships between characters. They based their results on brain scan of people reading a Harry Potter book.

Better forecasts for sea ice under climate change
New research will help pinpoint the impact of waves on sea ice, which is vulnerable to climate change, particularly in the Arctic where it is rapidly retreating.

Mutant protein takes babies' breath away
Researchers had never shown exactly how cells in the brain stem detect carbon dioxide and regulate breathing in humans. After taking a mutation from a two-month-old baby and expressing it in human astrocytes, they did exactly that -- and the research may lead to an early warning system to save premature infants with breathing trouble.

Penn team's game theory analysis shows how evolution favors cooperation's collapse
With a new analysis of the Prisoner's Dilemma played in a large, evolving population, University of Pennsylvania scientists found that adding more flexibility to the game can allow selfish strategies to be more successful. The work paints a dimmer but likely more realistic view of how cooperation and selfishness balance one another in nature.

How the hummingbird achieves its aerobatic feats
Although hummingbirds are much larger and stir up the air more violently as they move, the way that they fly is more closely related to flying insects than it is to other birds.

Firms pressure sales people to invest in costly internal negotiations: INFORMS study
In many firms sales people spend as much time negotiating internally for lower prices as they do interacting with customers. A new study appearing in the November issue of Marketing Science, a publication of the Institute for Operations Research and the Management Sciences, INFORMS, finds that firms should allow their sales people to 'waste' energy on internal negotiations. In fact, it says, firms should make the process wasteful on purpose.

When vaccines are imperfect
The control of certain childhood diseases is difficult, despite high vaccination coverage in many countries. One of the possible reasons for this is 'imperfect vaccines,' that is, vaccines that fail either due to 'leakiness,' lack of effectiveness on certain individuals in a population, or shorter duration of potency. In a paper publishing today in the SIAM Journal on Applied Mathematics, Felicia Magpantay et al. use a mathematical model to determine the consequences of vaccine failure and resulting disease dynamics.

A new tool for identifying onset of local influenza outbreaks
Hospital epidemiologists and others responsible for public health decisions do not declare the start of flu season lightly. All the extra precautions cost time and money, so they do not want to declare flu season too early. For hospitals, there is a strong incentive to define a really clear period as flu season.

'Green Revolution' changes breathing of the biosphere
The intense farming practices of the 'Green Revolution' are powerful enough to alter Earth's atmosphere at an ever-increasing rate, boosting the seasonal amplitude in atmospheric carbon dioxide to about 15 percent over the past five decades. That's the key finding of a new atmospheric model, which estimates that on average, the amplitude of the seasonal oscillation of carbon dioxide in the atmosphere is increasing at a rate of 0.3 percent every year.

Computer model sets new precedent in drug discovery
Merging expertise from computer science and synthetic drug design, the new model reveals that the drug efficacy of fusion-protein therapies depends on the geometric characteristics of a drug's molecular components. Use of the model could potentially replace the need to physically make and test new biologic drug designs, cutting down timelines and costs associated with drug development.

New model clarifies photoexcited thin-film lattice dynamics
No comprehensive study has yet been carried out to characterize the photoexcited lattice dynamics of an opaque thin film on a semi-infinite transparent substrate. As a result, ultrafast X-ray diffraction data for such samples can be challenging to interpret. Now a new study in the journal Structural Dynamics, from AIP Publishing, builds a model to help interpret such data.

Datasets used by policymakers, scientists for public health analyses inconsistent
Commercially available datasets containing a wealth of information about food and alcohol establishments differ significantly, raising concerns about their reliability as sources of information that could be used to set public policy or conduct scientific research, according to a University of Pittsburgh Graduate School of Public Health investigation. The analysis, funded by the Aetna Foundation, will be presented Monday at the American Public Health Association's annual meeting in New Orleans.

Credit score can also describe health status
A credit score also says something about a person's health status, according to a new analysis from a long-term study of the physical and mental health of more than 1,000 New Zealanders. An international team of researchers has found a strong relationship between low credit scores and poor cardiovascular health. They conclude that personal attributes leading to poor credit scores can also contribute to poor health.

Study predicts likely Ebola cases entering UK and US through airport screening
Researchers at the University of Liverpool have found that screening for Ebola at airports could be an effective method for preventing the spread of the disease into the UK and US, but due to the long incubation period of the virus, screening won't detect all cases.

Solving the puzzle of cooperation in group environments
Research has shown that when two individuals meet repeatedly they are more likely to cooperate with one another. Flávio Pinheiro and colleagues from the universities of Minho and Lisbon show that the most successful strategy for cooperation occurs only after an experience of group unanimous behavior.

Gene sequencing projects link two mutations to Ewing sarcoma subtype with poor prognosis
An international collaboration has identified frequent mutations in two genes that often occur together in Ewing sarcoma and that define a subtype of the cancer associated with reduced survival. The research, conducted by the St. Jude Children's Research Hospital-Washington University Pediatric Cancer Genome Project and the Institut Curie-Inserm through the International Cancer Genome Consortium, appears in the current issue of the scientific journal Cancer Discovery.

Stock market models help NYU researchers predict animal behavior
Modeling used to forecast fluctuations in the stock market has been discovered to predict aspects of animal behavior. The movement of zebrafish when mapped is very similar to the stochastic jump process, a mathematical model used by financial engineers. The model could improve the effectiveness of experiments, minimize the number of fish used, and allow researchers to make better use of their data following experiments.
