11:33 AM | Uncertain Dots 25: The Lightning Round
I got the time for the regular hangout wrong, and then we had some weird computer difficulties, so we only had ten minutes for Uncertain Dots this week. Which was enough time for me to say disparaging things about comic book movies, so, you know, if that interests you… Here’s the making of Interstellar story…

8:31 PM | Quantum Mechanics from a Classical Multiverse
Quantum mechanics can be hard to grasp, even for the physicists who use it every day. As a result, people have argued from the very birth of the field about what's really going on in quantum mechanical systems. To some extent, it doesn't really matter how you interpret things, provided everyone gets the same answers when they solve a physics problemThe plot of the movie Hot Tub Time Machine relied on the Many Worlds physics view of time travel. A new quantum mechanical approach may let us check […]

6:48 PM | How the Comet with the Funny Name Became a Globe-Trotting Internet Meme
I consider the Rosetta spacecraft one of the most exciting space voyagers in years. It is the first probe to orbit a comet, returning images of unprecedented richness. On November 12 it will place a lander on the comet’s surface, another exploratory breakthrough. Rosetta’s target, Comet 67P (its mouthy full name is Comet 67P/Churyumov-Gerasimenko) is […]The post How the Comet with the Funny Name Became a Globe-Trotting Internet Meme appeared first on Out There.

3:44 PM | Day o' Videos: Presentation and Flying Superconductors
The lab book today was a bit sparse and a bit dry.  This is a bit odd considering I got to play lab yesterday...  You'll see.First, here's an archival video of the presentation I did last Sunday for the TX APS section meeting here in College Station.  I fumble a few times, but the content is all there.  If you have any questions, they are very, very welcome! The second video has some kind of cool stuff in it.  Not stuff that went the way I had hoped mind you, but cool […]

11:21 AM | Hubble spots Comet Siding Spring flying past Mars
Comet Siding Spring makes near miss of Mars in this image form the Hubble Space Telescope. Click to enlarge! Image Credit: NASA, ESA, PSI, JHU/APL, STScI/AURA Last Sunday the comet C/2013 A1  Siding Spring flew past Mars at a distance of just 140 thousand kilometers, or one third of the distance between the Earth and the Moon. It's the closest we've ever seen a comet get to a rocky planet- so close, in fact, that initial observations suggested it might even hit.Data and observations […]

10:01 AM | L'Italia che vince!
E' un periodo che, per vari motivi, mi perdo informazioni. Per fortuna ci sono e-mail e newsletter che informano, e così accade anche per i risultati della spedizione italiana alle Olimpiadi Internazionali dell'Astronomia che dal Kirghizistan, sede della competizione, tornano con tre medaglie, un oro e due bronzi, festeggiati persino da Samantha Cristoforetti su twitter. Veniamo, però, al comunicato stampa inviatomi da Stefano Sandrelli:Sono tre, i premi vinti quest'anno dalla […]

8:18 AM | A nanoparticle-based alternative to Viagra
The majority of men who undergo radical prostatectomy for the treatment of prostate cancer will suffer from erectile dysfunction due to disruption of the cavernous nerve. This nerve has been identified as responsible for penile erection. The oral erectogenic PDE5 inhibitors like Viagra rely on the functioning of this nerve to provide the initial burst of nitric oxide necessary to initiate an erection. In this condition nanotechnology - in the form of a nanoparticle delivery system - may come to […]

Scientists will receive about $1.25 million from the Center for the Advancement of Science in Space to develop an implantable device that delivers therapeutic drugs at a rate guided by remote control. The device's effectiveness will be tested aboard the International Space Station and on Earth's surface.
