Scientists at Rice University are enhancing the natural antioxidant properties of cerium oxide, used in vehicle catalytic converters, to make it useful for medical applications.

Rice chemist Vicki Colvin led a team that created small, uniform spheres of cerium oxide and gave them a thin coating of fatty oleic acid to make them biocompatible.

The researchers say their discovery has… read more

Jellyfish energy efficiency to improve bio-inspired robotic designs for Navy

October 22, 2013

robotic_jellyfish

A team of researchers is designing life-like autonomous bio-inspired robotic jellyfish for the U.S Navy, based on the discovery of how jellyfish move with the lowest cost of transport of any animal.

Possible civilian applications include pollution monitoring, ecological studies, and cleaning oil in water.

Researchers have found that rather than moving continuously through water while swimming, jellyfish use a critical pause between the… read more

Shapley supercluster: most massive structure within a billion light-years

October 22, 2013

Shapley_Supercluster

While scanning the sky for the oldest cosmic light, ESA’s Planck satellite captured snapshots of some of the largest objects populating the Universe today: galaxy clusters and superclusters.

Several hundred galaxies and the huge amounts of gas that permeate them are depicted in this view of the core of the Shapley Supercluster, the largest cosmic structure in the local Universe.

The supercluster… read more

IBM Research unveils two new Watson-related projects from Cleveland Clinic collaboration

BarborakWatsonPaths

IBM Research has unveiled two new Watson-related cognitive technologies that are expected to help physicians make more informed and accurate decisions faster and to cull new insights from electronic medical records (EMR).

The “WatsonPaths” and “Watson EMR Assistant” projects are the result of a year-long research collaboration with faculty, physicians and students at Cleveland Clinic Lerner College of Medicine of Caseread more

Is a scientific definition of consciousness possible?

Consciousness arises from the mode in which billions of neurons communicate with one another, psychologists suggest

Parcellation of brain data into 194 cortical, subcortical and cerebellar ROIs.

UCLA psychologists have used brain-imaging techniques to study what happens to the human brain when it slips into unconsciousness.

Their research, published in the online open-access journal PLOS Computational Biology, is an initial step toward developing a scientific definition of consciousness, the researchers say.

“In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving… read more

Kinect-based program makes yoga accessible for the blind

October 20, 2013

An incorrect Warrior II yoga pose is outlined showing angles and measurements. Using geometry, the Kinect reads the angles and responds with a verbal command to raise the arms to the proper height.

University of Washington computer scientists have created a software program that watches a user’s movements and gives spoken feedback on what to change to accurately complete a yoga pose.

“My hope for this technology is for people who are blind or low-vision to be able to try it out, and help give a basic understanding of yoga in a more comfortable setting,” said

The Dream

Many people assume that this quest to interpret dreams has failed. This conclusion is premature, Kelly Bulkeley, former president of the International Association for the Study of Dreams and author of Dreaming in the World’s Religions: A Comparative History,” writes in The New York Times. …

“I have conducted several experiments in “blind analysis,” a technique developed with the help of the psychologist G. William… read more

IBM unveils concept for a future brain-inspired 3D computer

October 20, 2013

IBM 3D computer

IBM has unveiled a prototype of a new brain-inspired computer powered by what it calls “electronic blood,” BBC News reports.

The firm says it is learning from nature by building computers fueled and cooled by a liquid, like our minds.

The human brain packs phenomenal computing power into a tiny space and uses only 20 watts of energy – an efficiency IBM is keen to match.… read more

How the brain ‘takes out the trash’ while we sleep

October 18, 2013

cerebral_spinal_fluid

A new study shows that a recently discovered system that flushes waste from the brain is primarily active during sleep, giving fresh meaning to the old adage that a good night’s sleep clears the mind.

This revelation could transform scientists’ understanding of the biological purpose of sleep and point to new ways to treat neurological disorders.

“This study shows that the brain has different functional states… read more

Light triggers cancer death switch

(Credit: Cardiff University)

Cardiff University researchers have created a peptide (a small piece of protein), linked to a light-responsive dye, capable of switching “on” death pathways in cancer cells. The peptide remains inactive until exposed to external light pulses, which convert it into a cell death signal.

Complex mechanisms in healthy cells normally protect us from developing cancer. However, when the finely balanced networks of interactions between proteins… read more

Mathematical thinking area of brain identified; technique could lead to mind-reading devices, scientists say

October 18, 2013

ECoG responses (red: IPS region)

Researchers have found the first solid evidence that a specific brain region is activated in everyday conversation when people use numbers (or even imprecise quantitative terms, such as “more than”), according to a study by Stanford University School of Medicine scientists.

That brain region was previously found to be activated when people are asked to perform mathematical calculations, but only in a limited, unnatural experimental setting.

Those… read more

Creating a deep-sea Internet

University at Buffalo researchers are developing a deep-sea Internet that could lead to improvements in tsunami detection, offshore oil and natural gas exploration, surveillance, pollution monitoring, and other activities.

“A submerged wireless network will give us an unprecedented ability to collect and analyze data from our oceans in real time,” said Tommaso Melodia, UB associate professor of electrical engineering and the project’s lead researcher.… read more

Remember the much-debated “biobots” (remotely controlled cockroaches — see How to remotely control cockroach cyborgs and Kinect tracks bionic rescue roaches) created by researchers from North Carolina State University?

Well, here’s an update: they have now developed software that allows for mapping unknown environments — such as collapsed buildings — based on the movement of a swarm of the insect cyborgs.… read more
