The Effects of Social Media Monopolies
by Mark Fonseca Rendeiro in United Academics
Though some new statistical reports show signs of slowing down, we are still very much in the era of social media euphoria, where more and more people join up, sign in, and check their feeds as often as possible. ”Like” it or not- grievances are aired, ideas are sometimes exchanged, and a never ending stream of baby photos are shared at every minute of the day. On the surface, both regular users and professional researchers have observed and chronicled the list of achievements and p........ Read more »

Programming playground: Cells as (quantum) computers?
by Artem Kaznatcheev in Evolutionary Games Group
Nearly a year ago, the previous post in this series introduced a way for programmers to play around with biology: a model that simulated the dynamics of a whole cell at unprecedented levels of details. But what if you want to play with the real thing? Can you program a living cell? Can you compute [...]... Read more »

The Misguided Search for Validation via Social Media
by Jason Carr in Wired Cosmos
We human beings are social creatures. It’s natural for us to orient ourselves in terms of the world outside and what the people around us are thinking and doing. This socialization instinct is strongest in us when we’re young and still developing our own sense of identity. Historically speaking, this dynamic has typically played itself … Read More →...

Film preparations for oral drug delivery
by Maren Preis in Pharmaceutical Solid State Research Cluster (PSSRC)
Oral films have gained interest in the last couple of years. Films for oral application offer an interesting new approach for drug administration. Active pharmaceutical ingredients (API) can be implemented in thin-sheeted polymer film matrices. These dosage forms are intended to be placed in mouth to dissolve in the saliva without the need of additional liquid and without swallowing of a solid dosage form.... Read more »

Scientists Detect Magnetic Fingerprints of Defects in Solar Cells
by dailyfusion in The Daily Fusion
A new highly sensitive method of measurement allowed physicists form Helmholtz-Zentrum Berlin for Materials and Energy to directly detect defects in solar cells with atomic resolution. This findings can be used to optimize solar cells’ efficiency and decrease production costs.
HZB physicists have managed to localize defects in amorphous/crystalline silicon heterojunction solar cells. Now, for the first time ever, using computer simulations at Paderborn University, the scientists were ........ Read more »

Texas Unleashes Stampede for Science
by Perikis Livas in Tracing Knowledge
Stampede, the newest supercomputer at the Texas Advanced Computing Center (TACC) and one of the most advanced scientific research instruments in the world, fills aisle after aisle of a new 11,000-square-foot data center on the J.J. Pickle Research Campus. Through the glass machine room doors, you can see 182 racks holding more than 500,000 interconnected computer processors. Inside, wind whips from in-row coolers, wires snake over the racks and chilled water courses below the floor as Stampede p........ Read more »

Modern Privacy: More Access to Cells than Toilets
by Katja Keuchenius in United Academics
Most people in the world now live in a city, feeling pretty anonymous. An even bigger number of people don’t have to defocate out in the open anymore, but have access to a toilet. And then there’s this growing amount of people that can talk in private on their cells. But beware, these are false senses of privacy.... Read more »

Breakthrough Research Shows Chemical Reaction in Real Time
by Perikis Livas in Tracing Knowledge
The ultrafast, ultrabright X-ray pulses of the Linac Coherent Light Source (LCLS) have enabled unprecedented views of a catalyst in action, an important step in the effort to develop cleaner and more efficient energy sources.
Scientists at the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory used LCLS, together with computerized simulations, to reveal surprising details of a short-lived early state in a chemical reaction occurring at the surface of a catalyst sampl........ Read more »

X-ray Laser Explores How to Write Data with Light
by Perikis Livas in Tracing Knowledge
Using laser light to read and write magnetic data by quickly flipping tiny magnetic domains could help keep pace with the demand for faster computing devices.
Now experiments with SLAC’s Linac Coherent Light Source (LCLS) X-ray laser have given scientists their first detailed look at how light controls the first trillionth of a second of this process, known as all-optical magnetic switching.... Read more »

A great role model for collaborative science: meet the OpenWorm
by Eugenio Maria Battaglia in Science to Grok
Sometimes even big project could start from a tweet.
Matteo Cantarelli - member of the OpenWorm team - says: "It was 2007 when Giovanni Idili and I started - naively - talking about simulating the worm. We were approaching the problem after having hit common limits of artificial intelligence. We never got to write any code for the worm at that time, we just had lengthy conversations and paper reading sessions together."

Interestingly, some regions specialize in spam, while others focus on phishing for your bank account. ... Read more »

Surprising Control over Photoelectrons from a Topological Insulator
by Perikis Livas in Tracing Knowledge
Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface.
Researchers find TIs exciting partly because the electrons that flow swiftly across their surfaces are “spin polarized”: the electron’s spin is locked to its momentum, perpendicular to the direction of travel. These inter........ Read more »

Predicting Technological Progress: Putting Moore’s Law to the Test
by gunnardw in The Beast, the Bard and the Bot
Being able to predict the pace of technological development could be quite useful for a lot of people. No surprise then, that several models (or ‘laws’) have been posited that aim to describe how technological progress will unfurl (the most famous one probably being Moore’s law, for those interested: original article here). However, these laws [...]... Read more »

Let’s Explore Quantum Computing
by Jason Carr in Wired Cosmos
It’s fairly easy to surmise how quantum computing will evolve in the future if/when it becomes a reality. Devices that are currently based around a system of electronic circuits would eventually die off. Quantum devices would ultimately become the new standard in computing. While Peter Shor’s research showed how quantum algorithms would speed up advanced [...]... Read more »

Games, culture, and the Turing test (Part I)
by Artem Kaznatcheev in Evolutionary Games Group
Intelligence is one of the most loaded terms that I encounter. A common association is the popular psychometric definition — IQ. For many psychologists, this definition is too restrictive and the g factor is preferred for getting at the ‘core’ of intelligence tests. Even geneticists have latched on to g for looking at heritability of [...]... Read more »

Dead Sparrow Turned into Robot to Study Bird Behavior
by Jason Carr in Wired Cosmos
Researchers at Duke University recently took a major step toward better understanding how swamp sparrows use a combination of song and visual displays to communicate with one another. How they came about making this discovery, though, is what makes this story particularly newsworthy — they stuffed a deceased swamp sparrow with a miniature computer and some [...]... Read more »
