Even though Sony's offering a few free PlayStation 4 games at launch to PlayStation Plus members, the company apparently wants to extend its philanthropy to the entire PS4 consumer base. Every PlayStation 4 comes pre-loaded with a copy of The Playroom, which you may remember from E3 2013 as "that crazy demo thing that uses basically every piece of the DualShock 4 and PS4 Eye to amazing effect."
If you did miss the video and you're not able to watch at the moment, know this: The Playroom is a super neat addition to the PS4 console. It essentially acts as the Wii Sports for the PlayStation 4, showing off everything from the DualShock 4's lightbar to the PS4 Eye's depth-sensing functionality. It's also full of adorable little robots, should all that other stuff not suffice. We've dropped our full video walking through its features just below; the PlayStation 4 is planned for launch in "holiday 2013" at $400.
Update: Please excuse us if we've misled anyone -- the PlayStation 4 Eye does not come packed in with the console and DualShock 4. It's a separate $60 purchase, though The Playroom still ships with PS4 consoles.

Once an underdog in the Android world, Sony Mobile put out a strong showing earlier in the year with smartphones like the Xperia Z and Xperia ZL. With these devices the Japanese manufacturer seeks to differentiate itself with high-quality materials and outstanding designs. So it’s interesting to see that in its new mid-ranger, the Xperia SP, Sony is looking back to its smartphone design heritage, resurrecting ideas like the transparent element from last year’s NXT series.
On paper it’s packing reasonable specs, too — a dual-core Snapdragon S4 Pro, 1GB of RAM, a 4.6-inch 720p display and an 8-megapixel camera, not to mention LTE support. Not too long ago that would've been considered flagship territory. So, with a good-looking chassis and powerful internals, does Sony have a mid-range hit on its hands? Check past the break to find out.

Electron transfer is a process by which an atom donates an electron to another atom. It is the foundation of all chemical reactions, and is of intense research because of the implications it has for chemistry and biology. When two molecules interact, electron transfer takes place in a few quadrillionths (10-15) of a second, or femtoseconds (fsec), meaning that studying this event requires very time-sensitive techniques like ultrafast spectroscopy. However, the transfer itself is often influenced by the solution in which the molecules are studied (e.g. water), and this must be taken into account when such experiments are designed. In a recent Nature Communications paper, EPFL scientists have visualized for the first time how electron transfer takes place in one of the most common solvents, water.
For over twenty years, scientists have been trying to understand how an electron departs from an atom or molecule, travels through space in a solvent, and finally connects to an acceptor atom or molecule. Until now, experimental efforts have not borne much fruit, mostly because of the extremely short time periods involved in electron transfer. The problem is further complicated when we consider that the molecules of the commonest reaction solvent, water, are polar, which means that they respond to electron movement by influencing it. Understanding the real-time impact of the solvent is crucial, because it directly affects the outcome and efficiency of electron-transfer chemical reactions.
Majed Chergui's group at EPFL's Laboratory of Ultrafast Spectroscopy (LSU) employed a world-unique setup in their lab to observe the evolution of electron movement with unprecedented time-resolution. The scientists excited iodide in water with ultraviolet light, causing the ejection of an electron from the iodine atom. Using a technique called ultrafast fluorescence spectroscopy they observed the departure of the electron over different times between 60 fsec and 450 fsec. Previous research has always been limited between 200 fsec 300 fsec because once the electron exits, other processes take place that shade the longer periods of time and shorter timepoints have been inaccessible.
The experiment showed that the departure of the electron depends very much on the configuration of the solvent cage around the iodide. In chemistry, a 'solvent cage' refers to the way a solvent's molecules configure around an atom or molecule and 'try to hold it in place'. What the EPFL researchers found was that the polarized water molecules held the excited electron in place for a time, causing some structural re-arrangement of the solvent (water) in the process, while the driving force for electron ejection into the solvent is being reduced. Ultimately, the solvent cage does not prevent electrons from departing, but it slows down their departure stretching their residence time around iodine up to 450 fsec.
The breakthrough study shows how strongly the configuration and re-arrangement of the solvent affects electron departure. "It's not enough to consider only the donor and acceptor of the electron now you have to consider the solvent in between", says Majed Chergui. "If you are thinking about driving molecules by light into electron transfer processes, this is in a way telling the community 'watch out, don't neglect the solvent it is a key partner in the game, and the re-arrangement of the solvent is going to determine how efficient your reaction will be.'"
