Wireless brain sensor could unchain neuroscience from cables

Wireless brain sensor could unchain neuroscience from cables

PROVIDENCE, R.I. [Brown University] -- In a study in the journal Neuron, scientists describe a new high data-rate, low-power wireless brain sensor. The technology is designed to enable neuroscience research that cannot be accomplished with current sensors that tether subjects with cabled connections.

Experiments in the paper confirm that new capability. The results show that the technology transmitted rich, neuroscientifically meaningful signals from animal models as they slept and woke or exercised.

Images of brain after mild stroke predict future risk

A CT scan of the brain within 24 hours of a mild, non-disabling stroke can predict when patients will be at the highest risk of another stroke or when symptoms may worsen, according to new research published in the American Heart Association journal Stroke.

Like stroke, a transient ischemic attack (TIA) is caused by restricted blood supply to the brain. Symptoms may last only a few minutes.

Quiet as a mouse, but so much to hear

BUFFALO, N.Y. -- Micheal L. Dent, a University at Buffalo psychologist, listens to what is inaudible to others. And what she's hearing might one day help us better understand human hearing loss.

Maintaining a reliable value of the cost of climate change

The Social Cost of Carbon puts a dollar value on the climate damages per ton of CO2 released, and is used by - among others -policymakers to help determine the costs and benefits of climate policies. In the latest issue of the journal Science, a group of economists and lawyers urge several improvements to the government's Social Cost of Carbon figure that would impose a regular, transparent and peer-reviewed process to ensure the figure is reliable and well-supported by the latest facts.

The social brain: Does guessing others' intentions make a difference when we learn?

People regularly engage in sophisticated 'mentalizing' (i.e. guessing the intentions or beliefs of others) whenever they convince, teach, deceive, and so on. Research published this week in PLOS Computational Biology demonstrates the laws that govern these intuitions and how efficient they are for anticipating the behaviour of other people.

Jean Daunizeau and colleagues from INSERM and CNRS combine mathematical modelling, experimental psychology and behavioural economics to measure the sophistication of human 'mentalizing'.

Chicago summer jobs program for high school students dramatically reduces youth violence

A public summer jobs program for high school students from disadvantaged neighborhoods in Chicago reduced violent crime arrests by 43 percent over a 16-month period, according to a new study from the University of Chicago Crime Lab and the University of Pennsylvania. The randomized controlled trial is published in the journal Science.

Obesity and hypertension

The link between obesity and cardiovascular diseases is well acknowledged. Being obese or overweight is a major risk factor for the development of elevated blood pressure, and cardiovascular diseases. But it has net been known how obesity increases the risk of high blood pressure, making it difficult to develop evidence based therapies for obesity, hypertension and heart disease.

Higher birth weight indicates better performance in school

GAINESVILLE, Fla. -- It's no secret that low-birth-weight babies face significantly greater risks for certain health problems early on, such as respiratory distress or infection. Now, a new study from researchers at the University of Florida and Northwestern University shows that lower weights at birth also have an adverse effect on children's performance in school, which is likely due to the early health struggles small babies often face.
