A strange lonely planet found without a star

October 11, 2013

The planet is extremely cold and faint, about 100 billion times fainter in optical light than the planet Venus. Most of its energy is emitted at infrared wavelengths.

An international team of astronomers has discovered an exotic young planet that is not orbiting a star. This free-floating planet, dubbed PSO J318.5-22, is just 80 light-years away from Earth and has a mass only six times that of Jupiter. The planet formed a mere 12 million years ago — -a newborn in planet lifetimes.

It was identified from its faint and unique heat signature by the … read more

The man behind the Google brain: Andrew Ng and the quest for the new AI

May 9, 2013

Artificial.intelligence

There’s a theory that human intelligence stems from a single algorithm.

The idea arises from experiments suggesting that the portion of your brain dedicated to processing sound from your ears could also handle sight for your eyes. This is possible only while your brain is in the earliest stages of development, but it implies that the brain is — at its core — a general-purpose machine that can be tuned… read more

European regulators have approved the first therapy in the western world that can correct errors in a person’s genetic code, according to Amsterdam-based uniQure (formerly Amsterdam Molecular Therapeutics),

Europe has approved Glybera for treatment of Lipoprotein Lipase Deficiency (LPLD), a very rare, inherited disease. Patients with LPLD are unable to metabolize the fat particles carried in their blood, which leads to inflammation of the pancreas (pancreatitis).… read more

EPFL’s Institute of Microengineering has reached a remarkable 10.7% efficiency for a single-junction microcrystalline silicon solar cell, surpassing the previous world record of 10.1% held by the Japanese company Kaneka Corporation since 1998.

The efficiency increase was also achieved with with only 1.8 microns of photovoltaic active material — 100 times less material than with standard wafer-based crystalline silicon PV technology.

The new thin-film… read more

New research from the University of Copenhagen combines formal philosophy, social psychology, and decision theory to understand and tackle these phenomena.

“Group behavior that encourages us to make decisions based on false beliefs has always existed.

However, with the advent of the Internet and social media, this kind of behavior is more likely to occur than ever, and on a much larger scale, with… read more

John Moravec of Education Futures interviewed mathematician and science-fiction writer Vernor Vinge, noted for his foundational 1993 essay, “The Coming Technological Singularity.

“I’m still where I was in my 1993 essay that I gave at a NASA meeting, and that is that I define the Technological Singularity as being our developing, through technology, superhuman intelligence — or becoming, ourselves, superhuman intelligent through technology,” said Vinge.

“And,… read more

Northwestern Medicine researchers have developed a biodegradable nanoparticle  that stealthily delivers an antigen that tricks the immune system into stopping its attack on myelin and haltd a model of relapsing remitting multiple sclerosis (MS) in mice, according to new research.

The nanoparticles can also be applied to other immune-mediated diseases, including Type 1 diabetes, food allergies, and asthma.

Kim Suozzi, diagnosed at age 21 with brain cancer while studying neuroscience at college, passed away Thursday, January 17, 2013 at age 23.

The Society for Venturism, a cryonics advocacy and support group, started a charity fund for her cryonic suspension in August of 2012 and through an overwhelming amount of support from the extreme life extension community, enough funds were raised for her to be cryopreserved with Alcor.… read more

Pupil dilation reveals sexual orientation in new Cornell study

August 7, 2012

Blue Eye Macro

There is a popular belief that sexual orientation can be revealed by one’s pupil dilation when viewing attractive people, but there has been no scientific evidence.

Now Cornell University researchers have confirmed it in an experiment, using a specialized infrared lens to measure pupillary changes in participants watching erotic videos.

Pupils widened most to videos of people who participants found attractive, thereby revealing where they were on… read more

Moore’s Law is losing steam due to delayed introduction of next-generation extreme ultraviolet lithography (EUV), said experts at the 2012 International Symposium on Extreme Ultraviolet Lithography, EE Times reports.

EUV systems need light sources that are nearly 20 times more powerful than the ones used today to lay down patterns on next-generation chips that target sizes as small as 14 nm. Lithography experts said that… read more
