Imaging with an optical brush

Researchers at the MIT Media Lab have developed a new imaging device that consists of a loose bundle of optical fibers, with no need for lenses or a protective housing. The fibers are connected to an array of photosensors at one end; the other ends can be left to wave...

Dementia Risk Varies Significantly Among Racial And Ethnic Groups

In the largest and longest study thus far of ethnic disparities in dementia risk, researchers compared six ethnic and racial groups within the same geographic population and found significant variation in dementia incidence among them. The results are published online...

Decade of rising seas slowed by land soaking up extra water

New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise. A new study by scientists at NASA’s Jet Propulsion...

A hormone implicated in monogamy and aggression in animals also promotes trust and cooperation in humans in risky situations, Caltech researchers say. The findings, published the week of February 8 in the online edition of the Proceedings of the National Academy of...

New record for fastest data transmission

A new record for the fastest ever data rate for digital information has been set by UCL researchers in the Optical Networks Group. They achieved a rate of 1.125 Tb/s as part of research on the capacity limits of optical transmission systems, designed to address the...

Internet searches reflect vaping’s surge

The Oxford Dictionaries selected “vape”–as in, to smoke from an electronic cigarette–as word of the year in 2014. It turns out that Internet users’ search behavior tells a similar story. Between 2009 and 2015, the number of people in the...

Southwest sliding into a drier climate

The weather patterns that typically bring moisture to the southwestern United States are becoming more rare, an indication that the region is sliding into the drier climate state predicted by global models, according to a new study. “A normal year in the...

Lipid-based diets effectively combat Alzheimer’s in mouse model

Alzheimer´s disease (AD) is the most common disease underlying memory problems and dementia in the elderly. One of the invariable pathologies in AD is degeneration of cholinergic synapses in brain cortex and hippocampus. Despite enormous effort to find out an...

Worldwide bee epidemic linked to human cause: colony trafficking

Just as world travel is contributing to the Zika virus epidemic spreading through Latin America and into North America, so too is world traffic in bee colonies fueling a worldwide bee epidemic. The finding comes from a study by UC Berkeley and Exeter University...

Mothers may pass brain structure linked to depression to daughters

A study of 35 families led by a UC San Francisco psychiatric researcher showed for the first time that the structure of the brain circuitry known as the corticolimbic system is more likely to be passed down from mothers to daughters than from mothers to sons or from...
