Rapture of the nerds: will the Singularity turn us into gods or end the human race?

Posted by in categories: biotech/medical, finance, information science, mathematics, robotics/AI, singularity

Circa 2012


Hundreds of the world’s brightest minds — engineers from Google and IBM, hedge funds quants, and Defense Department contractors building artificial intelligence — were gathered in rapt attention inside the auditorium of the San Francisco Masonic Temple atop Nob Hill. It was the first day of the seventh annual Singularity Summit, and Julia Galef, the President of the Center for Applied Rationality, was speaking onstage. On the screen behind her, Galef projected a giant image from the film Blade Runner: the replicant Roy, naked, his face stained with blood, cradling a white dove in his arms.

At this point in the movie, Roy is reaching the end of his short, pre-programmed life, “The poignancy of his death scene comes from the contrast between that bitter truth and the fact that he still feels his life has meaning, and for lack of a better word, he has a soul,” said Galef. “To me this is the situation we as humans have found ourselves in over the last century. Turns out we are survival machines created by ancient replicators, DNA, to produce as many copies of them as possible. This is the bitter pill that science has offered us in response to our questions about where we came from and what it all means.”

For the September Journal Club we are taking a look at the new human trial data from the recent senolytics trial at the Mayo Clinic

A follow on study from their previous human trial targeting IPF. This time the researchers ran a study to see how senolytics influenced diabetic kidney disease and if it actually removes senescent cells in humans.


Senescent cells, which can release factors that cause inflammation and dysfunction, the senescence-associated secretory phenotype (SASP), accumulate with ageing and at etiological sites in multiple chronic diseases. Senolytics, including the combination of Dasatinib and Quercetin (D + Q), selectively eliminate senescent cells by transiently disabling pro-survival networks that defend them against their own apoptotic environment. In the first clinical trial of senolytics, D + Q improved physical function in patients with idiopathic pulmonary fibrosis (IPF), a fatal senescence-associated disease, but to date, no peer-reviewed study has directly demonstrated that senolytics decrease senescent cells in humans.

Moore’s Law Is Dying. This Brain-Inspired Analogue Chip Is a Glimpse of What’s Next

Posted by in categories: computing, neuroscience, physics

“Dark silicon” sounds like a magical artifact out of a fantasy novel. In reality, it’s one branch of a three-headed beast that foretells the end of advances in computation.

Ok—that might be too dramatic. But the looming problems in silicon-based computer chips are very real. Although computational power has exploded exponentially in the past five decades, we’ve begun hitting some intractable limits in further growth, both in terms of physics and economics.

Moore’s Law is dying. And chipmakers around the globe are asking, now what?

Studying a cell’s crawling motion in a fluid

Posted by in category: biotech/medical

Cell motility, the spontaneous movement of cells from one location to another, plays a fundamental role in many biological processes, including immune responses and metastasis. Recent physics studies have gathered new evidence suggesting that mammalian cells do not only crawl on solid substrates, including complex 3D mediums of a tissues, but can also swim in fluids.

In a recent study, a team of researchers at the University Grenoble Alpes and CNRS (National Center of Scientific Research) tried to shed light on the mechanisms behind the onset of motility cells in suspension, which would occur if they were moving in fluids. Their paper, published in Physical Review Letters, presents a model that couples actin and myosin kinetics with , which they applied to a spherical and a non-spherical shape.

“Recent studies have suggested that adhesion is not necessary for cells to move in a three-dimensional environment, and have even shown that cells of the immune system can swim when suspended in a fluid,” the researchers who conducted the study told Phys.org via email.

Researchers synthesize ‘impossible’ superconductor

Posted by in categories: biotech/medical, chemistry

Researchers from the U.S., Russia, and China have bent the rules of classical chemistry and synthesized a “forbidden” compound of cerium and hydrogen—CeH9—which exhibits superconductivity at a relatively low pressure of 1 million atmospheres. The paper came out in Nature Communications.

Superconductors are materials capable of conducting an electric current with no resistance whatsoever. They are behind the powerful electromagnets in , maglev trains, MRI scanners, and could theoretically enable power lines that deliver electricity from A to B without losing the precious kilowatts to thermal dissipation.

Unfortunately, the superconductors known today can only work at very low temperatures (below −138 degrees Celsius), and latest record (−13 degrees Celsius) requires extremely high pressures of nearly 2 million atmospheres. This limits the scope of their possible applications and makes the available superconducting technologies expensive, since maintaining their fairly extreme operating conditions is challenging.

Machine learning finds new metamaterial designs for energy harvesting

Posted by in categories: chemistry, robotics/AI, sustainability

Electrical engineers at Duke University have harnessed the power of machine learning to design dielectric (non-metal) metamaterials that absorb and emit specific frequencies of terahertz radiation. The design technique changed what could have been more than 2000 years of calculation into 23 hours, clearing the way for the design of new, sustainable types of thermal energy harvesters and lighting.

The study was published online on September 16 in the journal Optics Express.

Metamaterials are synthetic materials composed of many individual engineered features, which together produce properties not found in nature through their structure rather than their chemistry. In this case, the terahertz metamaterial is built up from a two-by-two grid of silicon cylinders resembling a short, square Lego.

Researchers’ new method enables identifying a person through walls from candidate video footage, using only WiFi

Posted by in categories: habitats, internet, law enforcement, security, surveillance

Researchers in the lab of UC Santa Barbara professor Yasamin Mostofi have enabled, for the first time, determining whether the person behind a wall is the same individual who appears in given video footage, using only a pair of WiFi transceivers outside.

This novel video-WiFi cross-modal gait-based person identification system, which they refer to as XModal-ID (pronounced Cross-Modal-ID), could have a variety of applications, from surveillance and security to smart homes. For instance, consider a scenario in which law enforcement has a of a robbery. They suspect that the robber is hiding inside a house. Can a pair of WiFi transceivers outside the house determine if the person inside the house is the same as the one in the robbery video? Questions such as this have motivated this new technology.

SETI Scientist: Aliens May Have Left a Spy Probe Orbiting the Sun

Posted by in categories: alien life, satellites

O.o I remember one time seeing an article I was not sure of basically talking about aliens coming out of the sun I thought it was crazy at the time but now I am not so sure o, o.


New research argues that ancient aliens could have turned space rocks orbiting near Earth into de-facto spy satellites.
