It's a scant 39 light years away, but even if we developed a propulsion system to get us there in a human lifetime, the inhospitable weather would make me select another destination. Good candidate for LONG distance study...

Scientists have discovered a new exoplanet that, in the language of “Star Wars,” would be the polar opposite of frigid Hoth, and even more inhospitable than the deserts of Tatooine. But instead of residing in a galaxy far, far away, this new world is, galactically speaking, practically next door.

The new planet, named GJ 1132b, is Earth-sized and rocky, orbiting a small star located a mere 39 light-years from Earth, making it the closest Earth-sized exoplanet yet discovered. Astrophysicists from MIT and elsewhere have published these findings today in the journal Nature.

Based on their measurements, the scientists have determined that the planet is a roasting 500 degrees Fahrenheit, and is likely tidally locked, meaning that it has a permanent day and night side, presenting the same face to its star, much like our moon is locked to the Earth.

Considering the obesity rate in the country and the FitBit craze, this could be a win-win for all of us.

Children have been harnessing energy from their steps ever since 1992, when L.A. Gear introduced sneakers that light up. For most adults, however, the ambient energy created by the simple act of walking is forever lost. Considering that the average person takes around 216 million steps in a lifetime, it’s a significant waste.

Inventor Laurence Kemball-Cook hopes to harness the lost energy at two points of contact: the shoe and the floor. In 2009, Kemball-Cook founded Pavegen, a company whose floor tiles can capture the power of footsteps. The technology uses compression to skim a tiny fraction of the energy created when a human steps on the tile. It’s been installed in more than 100 projects around the world, including a football stadium in Rio de Janeiro and a terminal in Heathrow Airport. The energy is stored in batteries inside the tiles, where it can then be used to power lighting, advertisements, and way-finding solutions, which guide people through an environment via directional arrows.

Now Kemball-Cook and his R&D team have turned their attention to the shoe itself, hoping to apply the same principles used in the tiles as a way to harness personal energy. “The idea is that the energy source would be readily available to the shoe wearer,” explains Kemball-Cook, who has been in discussions with major footwear manufacturers such as Nike and Reebok about ways the technology could be incorporated into consumer products. “You could walk from work and charge your phone en route instead of waiting to use a charger at home. Runners could charge their music players during a jog.”

Suicide Squad Trailer

Posted by Carles CJ Juzang on November 19, 2015 at 8:00am

We will see if DC has what it takes with characters outside of the Bat and Soops. Suicide Squad looks dark and procative but I am not sure the addition of Will Smith, Viola Davis Adewale Akinnuoye-Agbaje or Jared Leto's version of the Joker will make this a success. YOUR Thoughts and Feedback BSFS?

THE GODS OF EGYPT- A fantasy at best

Posted by Carles CJ Juzang on November 19, 2015 at 7:30am

Ok peeps just making you aware of THIS movie that hired a lot of special effects peeps of African decent. The FANTASY of this movie to me is why are the lead characters of this movie are not or at least look AFRICAN (hell I'll even go as far as to ask why don't they look Egyptian). GREAT to see Hollyhood exploring myths outside the European standard but again...sigh!  Asking for YOUR FEEDBACK BSFS PEOPLE! I am a fan of both Gerard Butler and Nikolaj Coster-Waldau but with the plethora of actors and actresses of African decent  as well as other parts of the known entertainment planet, all I can do is SMH.  I will probably wait until the digital version is available to purchase cause from the looks of the trailer it is mos def "Eye Candy". Your thoughts please?

I might do this at home, but I think this is already a neat demo done for many a high school or even college introductory physics class.

I disagree on one point in the video: we do use superconducting magnets specifically for levitation in the semiconductor industry in a few of our processes that require it. There are also several bullet trains that use this feature of super-cooled metal, thereby inducing superconductivity. You are welcome to invent other uses.

From Physics Database:

Dr. Amanda Barnard is an Office of the Chief Executive (OCE) Science leader, and head of the Virtual Nanoscience Laboratory at CSIRO. She received her PhD in 2003, followed by a Distinguished Postdoctoral Fellow in the Center for Nanoscale Materials at Argonne National Laboratory (USA), and the prestigious senior research position as Violette & Samuel Glasstone Fellow at the University of Oxford (UK) with an Extraordinary Research Fellowship at The Queen’s College.

In this talk Dr Amanda Barnard will take us through the latest advances in nanotechnology and answer the fantastic question: ‘Are nanoparticles alive?’ In the world of science fiction, nanotechnology is often shown as swarms of micro-machines that act without the need for human supervision. Much like their biological counterparts, these imagined devices even sometimes possess their own intelligence. The imagination of science fiction writers has taken this high tech fantasy beyond the reality. But scientists have imagination too, and increasingly they are taking nanomaterials to remarkable places with properties that sound stranger than fiction.

Okay, I have to admit: the bionic eye freaked me out. I'm trying to get used to it...


Researchers at the California NanoSystems Institute and the University of California, Los Angeles, have developed ultrathin, flexible, metal oxide semiconducting thin films for use in wearable or implantable biosensors. The devices, which are made using a straightforward printing technique, could be used as sensors in non-invasive health monitoring applications like smart contact lenses that monitor a person’s glucose levels, for example.

Power To Pluto...

This was a rather tongue-in-cheek article, I say that because all solutions point to the company web site and the products it produces or allegedly can produce. It does raise the issue of interplanetary and interstellar travel: charging your cell phone for selfies is kinda low on the scale of concerns once you fly beyond the "Goldilocks Zone" we currently inhabit. Like "The Martian," you're probably going to have to subsist on a lot of veggies even if you didn't like them as a kid since a burger and fries would be well...several billion miles away!

Imagine this. You have just parked your private space ship on Pluto, intrigued by all the recent NASA photos of the not-a-planet small wannabe-could-be-planet, and you realize your cell phone is on its last legs. Power-wise, that is. Not because you skipped the last two upgrades.

What to do? For sure, here on Pluto, a zillion miles away from the sun, rigging up some sort of solar screen recharger thing is out of the question. Not that you can't do that and not because it wouldn't work (eventually) but because you need power fast. There are Pluto selfies to take and tweets to be tweeted.

I will be featured in "Curse of the Tomb Seekers"!

Posted by Brandon Scott Pilcher on November 15, 2015 at 7:01am

On December 1st this year, Zimbell Publishing will release their new anthology Curse of the Tomb Seekers, which has an ancient Egyptian theme.

Disturbing the resting places of the Pharaoh’s was thought to bring down plagues and curses upon those that dared.  The Book of the Dead and other artifacts are coveted by historians and archeologists alike.  Untold treasures tempt the seekers to defy the ancient Gods.  Never in any other region of the world has there been such desire to disturb the Dead as in the once mighty Egypt.

And I am most pleased to inform you guys that yours truly is among their contributors! My story will be titled "The Gold Tusks of Ekhaptu", and it will be about a traveler to the ruins who discovers a shocking secret about the people who built it.

You can pre-order the anthology now on Zimbell's official page (see the link about) or Amazon.com.

Knowing Knowledge...

Science: 1 a : an area of knowledge that is an object of study b : something (as a sport or technique) that may be studied or learned like a science  c : any of the natural sciences (as biology, physics, or chemistry) Middle English science "the state of knowing, knowledge," from early French science (same meaning), from Latin scientia (same meaning)

Recently, there's been buzz on the Internet about a so-called mega structure (i.e. a Dyson Sphere) seen 1,500 light years away around its star. Related somewhat, astrophysicist Sara Seager thinks she can detect life on exoplanets by examining the spectrum of sodium (see BBC link below).

The quintessential question is - for any science discipline, from astronomy, biology, climate science and physics: how do scientists "know"?

They know first by sheer practice and enthusiasm. Everyone in STEM can recount the very instance that made such an impression on them that they decided to pursue a path to search the unknown - that labeled them "nerd"; weird and steeled their resolves against the tide of conformity. They studied all subjects with equal vigor, but particularly the science subjects. It formed a culture and a value system. Nerd went from epithet to web sites, social media forums; blerds, blogs and t-shirts.

They know by observation, forming hypothesis, doing experiments; rigorously defending and refuting positions...it sounds a lot like democracy, or at least how Thomas Jefferson envisioned it on the foundation of his "trinity of three greatest men." If knowing knowledge is thesis, then it's antithesis is prideful, unknowing ignorance.

Scientists and engineers will know knowledge, test it, debate it; refute it. They will confirm an ancient civilization that existed in our past...or, not. They have consensus on climate change, not conspiracy. I'm sure they would rather be wrong. They have a vested interest beyond an elaborate Ponzi scheme: their families. Some legacies have far more value than money.

Pseudoscience differs from erroneous science. Science thrives on errors, cutting away one by one. False conclusions are drawn all the time, but they are drawn tentatively. Hypotheses are framed so they are capable of being disproved. A succession of alternative hypotheses is confronted by experiment and observation. Science gropes and staggers toward improved understanding. Proprietary feelings are of course offended when a scientific hypothesis is disproved, but such disproofs are recognized as central to the scientific enterprise.

Pseudoscience is just the opposite. Hypotheses are often framed precisely so they are invulnerable to any experiment that offers a prospect of disproof, so even in principle they cannot be invalidated. Practitioners are defensive and wary. Skeptical scrutiny is opposed. When the pseudoscientific hypothesis fails to catch fire with scientists, conspiracies to suppress it are deduced.

Hacking Photosynthesis...

See previous post this year Mimicking Nature. I derived the title of the post from a supporting link to the article below suggesting that scientist had "hacked photosynthesis" and I thought it catchy. The fact that Argonne National Laboratory, Australian researchers (see link in the article) and now Florida State University have achieved this is exciting. What will be interesting are the moneyed interests that will ally against this advancement and sadly, throw lobbyists and dollars towards our elected officials to delay or squash it totally. Our economy is tied to commerce, but in essence this would be like [paraphrased] "living in the canopy, and burning down the forest." *

It’s one of the holy grails of scientific research: discovering a way of replicating the natural process of photosynthesis, such that light could be easily converted into energy for other purposes, just like a plant does. And now researchers in the US have discovered an artificial material that lets them mimic this system to create a clean, sustainable source of power.

Researchers at Florida State University have discovered a method of using manganese oxide – also known as birnessite – to capture sunlight and then use that solar energy to create an oxidation reaction, breaking down water (H2O) into hydrogen (H) and oxygen (O2). Oxidation occurs during photosynthesis, and by replicating this part of the natural process, we might be able to produce energy in new ways via a simple, practical mechanism.

Two icy volcanoes may lurk near Pluto’s south pole, images from NASA’s New Horizons spacecraft suggest.

The images show two mountains roughly circular in shape and with deep depressions in their centers. One, Wright Mons, is 3 to 5 kilometres high, while the other, Piccard Mons, is up to 6 kilometres high.

They resemble icy volcanoes, known as cryovolcanoes, on Neptune’s moon Triton and other frozen worlds. Flowing ice, rather than hot lava, fuels cryovolcanoes.

“We’re not yet ready to announce we have found volcanic constructs at Pluto, but these sure look suspicious and we’re looking at them very closely,” says Jeff Moore, a planetary scientist at NASA’s Ames Research Center in Moffett Field, California, who heads the New Horizons geology team. Moore spoke on November 9 at the American Astronomical Society’s Division for Planetary Sciences meeting in National Harbor, Maryland.

What’s the difference between matter and antimatter? Sometimes nothing, a new study finds.

Scientists at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) discovered that antimatter protons, called antiprotons, act just like their ordinary-matter cousins when they are close enough to interact via the so-called strong nuclear force, which binds protons and neutrons together into atomic nuclei.

Antimatter is essentially the opposite of matter, in which the subatomic particles (protons and electrons) of antimatter have charges opposite to those of ordinary matter. In an ordinary block of stuff, for instance, the protons are positively charged, and the electrons carry negative charges. In antimatter, the antiprotons are negatively charged, while the antielectrons (called positrons) are positively charged. When antimatter and matter touch, they annihilate each other and produce energy in the form of gamma radiation.

Beauty...

Physicists at JILA have made their "quantum crystal" of ultracold molecules more valuable than ever by packing about five times more molecules into it. The denser crystal will help scientists unlock the secrets of magnets and other, more exotic materials.

The crystal is actually a gas of particles trapped in 3-D formation by laser beams. The trap, called an optical lattice, has wells—local regions of low energy—like an egg carton made of light. The researchers maneuvered a single molecule into each well, successfully filling about 25 percent of the crystal. The structure has an advantage over a real crystal, as it is made of scientifically interesting molecules that normally would not crystallize.

Described in the Nov. 6, 2015, issue of Science,* the JILA crystal is useful for studying correlations among the molecules' "spins," or rotations, a quantum behavior related to magnetism. The denser crystal will enable scientists to study and model complex effects such as how spin correlations or entanglement—a quantum link between the properties of separated particles—spread through a large system. Scientists might use these effects, for example, to make novel materials for electronics or other applications.
