8:59 PM | Network Theory Seminar (Part 2)
  This time I explain more about how ‘cospans’ represent gadgets with two ends, an input end and an output end: I describe how to glue such gadgets together by composing cospans. We compose cospans using a category-theoretic construction called a ‘pushout’, so I also explain pushouts. At the end, I explain how this gives […]

7:38 PM | Engineers find a way to win in laser performance by losing
To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now engineers have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they've invented a way to win by losing.

4:14 PM | Dispelling a misconception about Mg-ion batteries
Researchers used supercomputer simulations to dispel a popular misconception about magnesium-ion batteries that should help advance the development of multivalent ion battery technology.

4:09 PM | Light bending material facilitates the search for new particles
Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers have designed a material that makes it much easier to distinguish the particles. The material manipulates the Cherenkov radiation from particles with high momentum so that they get a distinct light cone angle.

3:57 PM | Magnetic mirrors enable new technologies by reflecting light in uncanny ways
Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial.

3:27 PM | Entangled States at TED-Ed
The fourth video I wrote for TED-Ed is now live: Einstein’s Brilliant Mistake: Entangled States. The title is not just an Elvis Costello reference, but gets at the fact that while the Einstein, Podolsky, and Rosen paper was wrong in that the local hidden variable theories they favored are impossible, it turned out to be…

3:00 PM | A Close Encounter of the Martian Kind
A comet on express delivery from the Oort cloud of rock and ice that surrounds our Solar System makes a close approach of Mars this weekend. Martian satellites are already hunkering down against the potential onslaught of debris.Comet C/2013 A1, aka Siding Spring, shown as the reddish central object in four snapshots by NASA's NEOWISE mission in July 2014. Credit: NASA/JPLOn Sunday October 19th, comet C/2013 A1, familiarly known as comet Siding Spring, will fly within 87,000 […]

1:24 PM | HD 97658b, una super-Terra identificata con la tecnica della spettroscopia
Gli studi effettuati sul nostro Sistema Solare non ci permettono di arrivare a conclusioni certe in merito alle caratteristiche che esso può avere in comune, o meno, con gli altri sistemi planetari. Tuttavia, da quando la NASA nel 2009 ha messo in orbita il satellite Kepler, le cose stanno cambiando e oggi abbiamo una lista di […]

1:11 PM | What happened in the first instants after the Big Bang?
One of the biggest science stories of 2014 came out of the BICEP2 cosmic microwave background polarization experiment. Last spring, the BICEP2 researchers announced they had measured something known as B-mode or tensor-mode polarization, a particular twisting of light that is the hallmark of primordial gravitational waves. Those waves in turn would be a strong […]

12:52 PM | The Copernicus Complex by Caleb Scharf
I enjoyed Caleb Scharf’s previous book, Gravity’s Engines a good deal, so I was happy to get email from a publicist offering me his latest. I’m a little afraid that my extreme distraction of late hasn’t really treated it fairly, but then again, the fact that I finished it at all in my current state…

12:32 PM | Your Life On Earth
Have you ever wondered how far you’ve traveled through space in your lifetime? Or how many times your heart has beaten compared to that of a blue whale, or a hummingbird? Or maybe you’d like to know how many cups of coffee, or pints on beer, were available per person when you were born as […]

12:07 PM | New project looks at aircraft materials defects micro- and nanoscale levels
UT Arlington engineering professors have received a $451,781 Air Force Office of Scientific Research grant to examine the material surface at the micro- and nano-scale level that will provide clues for predicting fatigue in aircraft parts.

9:54 AM | What does swimming the Channel have to do with physics? Read on…
As the IOP’s own research has shown only too clearly, girls in schools are not progressing to A level physics in large numbers. How many do take the subject varies by school in quite significant ways and it looks as if the school ethos must be playing a substantial part. But for some girls, physics […] The post What does swimming the Channel have to do with physics? Read on… appeared first on physicsfocus.org.

9:10 AM | Controlling the size and shape of graphene-based multilayer structures
Researchers have developed a novel yet simple technique, called 'diffusion driven layer-by-layer assembly', to construct graphene into porous three-dimensional (3D) structures for applications in devices such as batteries and supercapacitors.

8:59 AM | Cleansing the ionic impurities in LCDs with nanoparticles
Impurities during the production process of liquid crystal devices result in mobile ions that influence the LCs' field-induced switching phenomena, resulting in a phenomenon called image sticking, or ghosting. Researchers now have developed a method to reduce the presence of excess ions by doping LCDs with ferroelectric nanoparticles. They demonstrate that this reduction of free ions has coherent impacts on the LC's conductivity, rotational viscosity, and electric field-induced nematic […]
