Researchers’ deep learning algorithm solves Rubik’s Cube faster than any human

Posted by in categories: information science, mathematics, robotics/AI

Since its invention by a Hungarian architect in 1974, the Rubik’s Cube has furrowed the brows of many who have tried to solve it, but the 3D logic puzzle is no match for an artificial intelligence system created by researchers at the University of California, Irvine.

DeepCubeA, a learning algorithm programmed by UCI scientists and mathematicians, can find the solution in a fraction of a second, without any specific domain knowledge or in-game coaching from humans. This is no simple task considering that the cube has completion paths numbering in the billions but only one goal state—each of six sides displaying a solid color—which apparently can’t be found through random moves.

For a study published today in Nature Machine Intelligence, the researchers demonstrated that DeepCubeA solved 100 percent of all test configurations, finding the to the goal state about 60 percent of the time. The algorithm also works on other combinatorial games such as the sliding tile , Lights Out and Sokoban.

Ebola spreads to largest city yet in DR Congo

Posted by in category: biotech/medical

The Democratic Republic of Congo has confirmed the first case of Ebola in the eastern city of Goma, a major transport hub.

The World Health Organization (WHO) said the case could be a “game-changer” given the city’s population of more than two million.

But the WHO expressed confidence in plans to deal with the diagnosis.

‘Greywater’ Could Help Solve Colorado’s Water Problems. Why Aren’t We All Using It?

Posted by in category: futurism

While greywater use was legalized in 2013, access to it is limited across the state because only Denver, Castle Rock and Pitkin County have adopted a code to regulate systems.

Physicists Reverse Time for Tiny Particles Inside a Quantum Computer

Posted by in categories: computing, mathematics, particle physics, quantum physics

Time goes in one direction: forward. Little boys become old men but not vice versa; teacups shatter but never spontaneously reassemble. This cruel and immutable property of the universe, called the “arrow of time,” is fundamentally a consequence of the second law of thermodynamics, which dictates that systems will always tend to become more disordered over time. But recently, researchers from the U.S. and Russia have bent that arrow just a bit — at least for subatomic particles.

In the new study, published Tuesday (Mar. 12) in the journal Scientific Reports, researchers manipulated the arrow of time using a very tiny quantum computer made of two quantum particles, known as qubits, that performed calculations. [Twisted Physics: 7 Mind-Blowing Findings]

At the subatomic scale, where the odd rules of quantum mechanics hold sway, physicists describe the state of systems through a mathematical construct called a wave function. This function is an expression of all the possible states the system could be in — even, in the case of a particle, all the possible locations it could be in — and the probability of the system being in any of those states at any given time. Generally, as time passes, wave functions spread out; a particle’s possible location can be farther away if you wait an hour than if you wait 5 minutes.

An Interview with Dr. María Blasco

Posted by in categories: biotech/medical, life extension

Our Ending Age-Related Diseases conference in New York is over for this year and has been a huge success. We had the opportunity to interview one of the speakers, Dr. Mar í a Blasco, during the conference, and we asked her more about her work with telomeres, telomerase therapy, and aging.

Telomere loss is a proposed reason we age

Telomere attrition—the wearing out of your chromosomes’ protective caps with age—is widely thought to be one of the major drivers of aging. With each division, telomeres shorten a little bit, and after 50–70 divisions, they become critically short. Once this threshold (the Hayflick limit) is hit, cells undergo replicative senescence, and their division comes to a grinding halt.

Differences in MS patients’ cerebrospinal fluid may be key to drugs that halt progression

Posted by in categories: biotech/medical, neuroscience

The disability burden for people with multiple sclerosis (MS) can vary significantly depending on whether they have a relapsing/remitting form of the disease, where they experience periods of clinical remission, or a progressive form, where they have continued neurological deterioration without clinical remission. Effective therapies exist for managing relapsing/remitting MS, but treatment for progressive MS has proved more challenging. Now, a new paper published in the journal Brain from researchers at the Advanced Science Research Center (ASRC) at The Graduate Center, CUNY and Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai has identified potential mechanisms that may inform the development of therapies that effectively manage progressive MS.

Previous research had suggested that dysfunction of neuronal —the energy-producing subcellular organelles—occurs in the brains of MS with progressive clinical disability. However, the underlying this process remained elusive.

“Because the brain is bathed by the cerebrospinal fluid (CSF), we asked whether treating cultured neurons with the CSF from MS patients with a relapsing/remitting or a progressive disease course would possibly elicit different effects on neuronal mitochondrial function,” said the study’s primary investigator Patrizia Casaccia, Einstein Professor of Biology at The Graduate Center and founding director of the Neuroscience Initiative at the ASRC. “We detected dramatic differences in the shape of the neuronal mitochondria and their ability to produce energy. Only exposure to the CSF from progressive MS patients caused neuronal mitochondria to fuse and elongate while rendering them unable to produce energy. We therefore searched for potential mechanisms of CSF-induced neurodegeneration with the intent to define therapeutic strategies.”
