Computer scientists Computer scientists Lior Shamir and Jane Tarakhovsky of Lawrence Technological University in Michigan have developed a program that analyzes paintings in a manner similar to how expert art historians perform their analysis, and conducted an experiment that showed that machines can outperform untrained humans in the analysis of fine art.
In the experiment, the researchers used approximately 1, 000 paintings of 34 well-known artists, and let the computer… read more

Cornell biomedical engineers have discovered a new way to destroy metastasizing cancer cells traveling through the bloodstream by hitching cancer-killing proteins along for a ride on life-saving white blood cells.
“These circulating cancer cells are doomed,” said Michael King, Cornell professor of biomedical engineering and the study’s senior author.
“About 90 percent of cancer deaths are related to metastases, but now we’ve found a way to… read more

A novel approach to the question of life’s origin, proposed by two Arizona State University scientists — Paul Davies, an ASU Regents’ Professor and director of the Beyond Center for Fundamental Concepts in Science, and Sara Walker, a NASA post-doctoral fellow at the Beyond Center — in an open-access Journal of the Royal Society Interface paper, attempts to dramatically redefine the problem.
The authors shift… read more

In a paper published online in the journal ACS Nano, Joshua Goldberger, assistant professor of chemistry at Ohio State University, and colleagues describe how they created a stable, one-atom-thick single layer of germanium atoms.
In this form, the crystalline material is called germanane.

This is the first proven biological signature of a starburst on our earth. The age determination of the deep-drill core from the Pacific Ocean showed that the supernova explosion must have occurred about 2.2 million years ago, roughly around the… read more

This summer Google set a new landmark in the field of artificial intelligence with software that learned how to recognize cats, people, and other things simply by watching YouTube videos (see “Self-Taught Software“).
That technology, modeled on how brain cells operate, is now being put to work making Google’s products smarter, with speech recognition being the first service to benefit, Technology Review reports.… read more

Black holes are growing faster than previously thought possible, according to new research published Wednesday in the Astrophysical Journal.
Even the black hole in our own Milky Way Galaxy, which otherwise appears very quiet, has probably been consuming the equivalent of one Sun every 3000 years.
Until recently, astronomers thought that black holes grow mostly when galaxies crash into each other, at which time a large… read more

A team of neuroscientists led by Professor Anthony Zador, Ph.D., of Cold Spring Harbor Laboratory have proposed a revolutionary new way to create a connectivity map (“connectome”) of the whole brain of the mouse at the resolution of single neurons: high-throughput DNA sequencing.
The only current method for obtaining the connectome with high precision relies on laboriously examining individual cell-to-cell contacts (synapses) in electron microscopes, which is slow, expensive… read more

A team of neuroengineers at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects.
Several copies of the novel low-power device, described in the open-access Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field.… read more

Henry Markram’s controversial proposal for the Human Brain Project (HBP) — an effort to build a supercomputer simulation that integrates everything known about the human brain, from the structures of ion channels in neural cell membranes up to mechanisms behind conscious decision-making — may soon fulfill his ambition.
The project is one of six finalists vying to win €1 billion (US$1.3 billion) as one of the European Union’s two new… read more

National University of Singapore’s (NUS) engineers have created efficient artificial muscles that could one day carry 80 times their own weight and extend to five times their original length when carrying the load.
The team’s invention could lead to life-like robots with superhuman strength and ability and convert and store energy, which could help the robots quickly charge themselves.
Powerful human-like muscles for robots… read more

“Touch was largely bypassed by the digital revolution, except for touch-screen displays, because it seemed too difficult to replicate what analog haptic [touch] devices can produce,” said Deli Wang, a professor of Electrical and Computer Engineering (ECE) in UC San Diego’s… read more
