Whitehead Institute scientists and associates have modified red blood cells (RBCs) to carry a range of valuable therapeutic and diagnostic payloads — such as drugs, vaccines, and disease-detecting imaging agents — for delivery to specific sites throughout the body.

Wireless vehicle networks could make driving safer, more efficient, and less polluting, but the cost of deployment will be significant, MIT Technology Review reports.
This week, officials from the U.S. Department of Transportation in Washington, DC, will see the technology in action, in a demonstration organized by experts from the University of Michigan’s Transportation Research Institute and various communications equipment and car manufacturers.… read more

The apparent velocity of time is a big fat cognitive illusion and ,,, there may be a way to slow the velocity of our later lives, Richard A. Friedman, a professor of clinical psychiatry and the director of the psycho-pharmacology clinic at the Weill Cornell Medical College, writes in The New York Times. …
If you want time to slow down, become a student again.… read more

Two Stanford researchers have discovered that harvester ants determine how many foragers to send out of the nest in much the same way that Internet protocols discover how much bandwidth is available for the transfer of data.
The researchers are calling it the “anternet.”
Deborah Gordon, a biology professor at Stanford, has been studying ants for more than 20 years.
When she figured out how the… read more

The MITRE Corporation hired two University of Virginia engineeering students to build an unmanned aerial vehicle, using 3D printing technology, part of a Department of the Army project to study the feasibility of using such planes.
The result was a plane with a 6.5-foot wingspan, made from assembled “printed” parts. It achieved a cruising speed of 45 mph and is only the third 3D-printed plane known to… read more

Samsung plans to start mass production of displays using plastic rather than glass to make mobile devices unbreakable, lighter, and bendable, to be released in the first half of next year, The Wall Street Journal reports.
Samsung’s flexible displays will incorporate OLEDs, a display technology that the South Korean company is already using in its smartphones and television sets. OLEDs are thin and can be… read more
The February 2013 event near Chelyabinsk, Russia “has sparked a realization that the incoming rate of small space rocks may be much higher than previously thought, and their impact greater than previously thought,” according to Near-Earth Objects: Responding to the International Challenge, an open-access booklet just published by Secure World Foundation.
The booklet is the first to both bring together the reviews of the… read more

Nanoengineers at the University of California, San Diego have developed a novel technology that can fabricate, in mere seconds, microscale three dimensional (3D) structures out of soft, biocompatible hydrogels.
Near term, the technology could lead to better systems for growing and studying cells, including stem cells, in the laboratory. Long-term, the goal is to be able to print biological tissues for regenerative medicine.
For… read more

An increase in cerebral pressure may cause dementia or even destroy the brain, but there’s no reliable sensor available (they quickly corrode), and current intracranial pressure systems keep patients in a hospital for days or weeks.
So Fraunhofer Institute for Biomedical Engineering (IBMT) researchers have developed a small implantable sensor for cerebral pressure that’s waterproof, using a casing made from high-grade titanium. It’s… read more

An algorithm that extends an artificial-intelligence technique to new tasks could aid in analysis of flight delays and social networks.
Much artificial-intelligence research is concerned with finding statistical correlations between variables: What combinations of visible features indicate the presence of a particular object in a digital image? What speech sounds correspond with instances of what words? What medical, genetic, and environmental factors are correlated with what diseases?
As… read more
Machines will achieve human-level intelligence by 2028 (median estimate: 10% chance), by 2050 (median estimate: 50% chance), or by 2150 (median estimate: 90% chance), according to an informal poll at the Future of Humanity Institute (FHI) Winter Intelligence conference on machine intelligence in January.
“Human‐level machine intelligence, whether due to a de novo AGI (artificial general intelligence) or biologically inspired/emulated systems, has a macroscopic probability to occurring… read more

A team of sleep researchers led by UC Riverside psychologist Sara C. Mednick has confirmed the mechanism that enables the brain to consolidate memory and found that a commonly prescribed sleep aid enhances the process.
Those discoveries could lead to new sleep therapies that will improve memory for aging adults and those with dementia, Alzheimer’s, and schizophrenia.
Earlier research found a correlation between sleep spindles —… read more
