4:00 AM | POLARBEAR misura i modi-B del ‘lensing’ gravitazionale
Un gruppo internazionale di fisici hanno misurato un ‘segnale caratteristico’ nella polarizzazione della radiazione cosmica di fondo (Cosmic Microwave Background, CMB) che potrà permettere di mappare la struttura su grande scala dell’Universo, determinare la massa del neutrino e magari di svelare alcuni misteri legati alle enigmatiche materia scura ed energia scura. In un articolo pubblicato sulla […]

9:30 PM | Unlocking The Other Senses of Space
These days it’s no surprise to come across a gallery of amazing astronomy images. The Hubble Space Telescope, the other NASA great observatories and space probes, the European Space Agency and European Southern Observatory, and many, many dedicated amateurs (among other sources) provide a steady flow of visual riches. Mind-boggling beauty shows up every day; […]The post Unlocking The Other Senses of Space appeared first on Out There.

2:34 PM | On Not Talking, for the Right Reasons
Over at Backreaction, Bee has a nice piece on our current age of virality. Toward the end, she discusses some of the ways this applies to science, specifically a quote from this Nature article about collaborative efforts to measure “big G”, and a story about a Chinese initiative to encourage collaboration. She writes of the…

2:05 PM | Researchers break nano barrier to engineer the first protein microfiber
Researchers have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale - a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.

1:36 PM | Pickup Coils, Faraday's Law and Back in the Lab! Lab Book 2014_10_23
 As always, look to the bottom of the post for background on what's going on.Finally, enough of theory and presentations!  I got back to the lab today!  Here’s the apparatus I built/used.NOTE:   As always, look to the bottom of the post for background on what's going on.No, the oscilloscope is not sticking its tongue out, that’s a floppy disc.  Remember those?  The small solenoid is what’s deemed a pickup coil. It’s the first […]

1:34 PM | Podcast: The Infinite Universe
Is the universe infinite? Or is it confined to a finite amount of space? Is it shaped like a donut, or does it stretch on forever as an infinite plane? A lot of people wonder about these questions, and a few people are actually trying to answer them. Like astrophysicist and cosmologist David Spergel of Princeton University. He and his colleagues are looking for clues about the shape of the universe, because they think it could help them determine if the universe is finite or...something […]

1:18 PM | How Fidel Castro Helped Bring Us the Hubble Space Telescope
Fifty two years ago this week, the world was gripped by the unfolding drama of the Cuban Missile Crisis. Most of the world remembers it as a showdown between President John F. Kennedy and Soviet Premier Nikita Khrushchev to remove newly installed nuclear missiles from Cuba, a crisis that was probably the closest the world got to World War III.President Kennedy and other members of his cabinet ponder their next move during the Cuban Missile Crisis.Image: JFK Presidental Library and MuseumIn the […]

12:30 PM | RF heating of magnetic nanoparticles improves the thawing of cryopreserved biomaterials
Successful techniques for cryopreserving bulk biomaterials and organ systems would transform current approaches to transplantation and regenerative medicine. However, while vitrified cryopreservation holds great promise, practical application has been limited to smaller systems (cells and thin tissues) due to diffusive heat and mass transfer limitations, which are typically manifested as devitrification and cracking failures during thaw. Now researchers leverage a clinically proven technology […]

12:00 PM | New Physics Drawings File: Springs
I added a new file to the Physics Drawings page. The file has my interpretation of stretched springs for use in physics homework, assessments, or presentations. All the files open in LibreOffice and compatible applications. They are CC licensed, so go nuts with using them.

11:00 AM | Apps and Ebola...
Technology ReviewPerhaps the sanest proposal I've heard so far, using technology to get people to the necessary treatment, track patients accurately; contain and control a pathogen before its R0 of 2 out of apathy based on xenophobia and tribalism grows exponentially to Bubonic proportions. With this country's current disastrous love affair with austerity, I'm not talking about the ubiquitous "there"..."We live in a society exquisitely dependent on science and technology, in which hardly anyone […]

10:32 AM | NASA to test emerging super-black nanotechnology on the International Space Station
An emerging super-black nanotechnology that is to be tested for the first time this fall on the International Space Station will be applied to a complex, 3-D component critical for suppressing stray light in a new, smaller, less-expensive solar coronagraph designed to ultimately fly on the orbiting outpost or as a hosted payload on a commercial satellite.

9:03 AM | Graphene-based biomimetic soft robotics platform
Among the various robotic actuation mechanisms driven by different stimuli, light-driven systems have garnered more and more attention due to their advantages in wireless/remote control, localized rather than whole-field driven capabilities, and electrical/mechanical decoupling. Inspired by the photothermal effect of graphene in biomedical applications, researchers have now demonstrated an easily fabricated and remote/wireless control light-driven approach to actuation mechanism based on […]

12:17 AM | When genius fails us
Of all the articles I’ve written over the last four years, none elicited stronger responses than “The Problem of Richard Feynman”. While many people responded positively, I was also lambasted by a conservative blogger, accused of trying to boost sales of my nonexistent book or otherwise make money on an unpaid blog, and generally told […]
