8:34 AM | Breakthrough method for studying catalyst dynamics under actual operating conditions
The process uses a technique called high-resolution electron microscopy to monitor changes in the catalyst structure during the catalytic process. Unlike conventional electron microscopy, which has considerable pressure and temperature limitations, this new technique allows scientists to view these reactions under real-life conditions.

8:20 AM | Centre for Green Nanotechnology launched in South Africa
The establishment of the University of the Western Cape's Centre for Green Nanotechnology was made a reality through a positive partnership between the University of Missouri (UM) ?and UWC that has spanned approximately 30 years.

8:00 AM | SHE Waddles in Beauty, Like the Night
I saw, via twitter, so links to a story that seems to be a repeat from a few months ago: about a bra (dubbed SHE) that delivers a jolt to would-be attackers. The problem with a majority of them: they claim the shock is 3,800 kV (kilovolts). That’s curious jargon, to use that number and [...]

7:30 AM | The electric slide dance of DNA knots
DNA has the nasty habit of getting tangled and forming knots. Scientists study these knots to understand their function and learn how to disentangle them. Researchers have now devised and tested a method based on the application of electric fields and optical tweezers.

6:25 AM | Researchers create nano-vaccine for dust-mite allergies
Researchers have created a vaccine for dust-mite allergies. In lab tests and animal trials, the nano-sized vaccine package was readily absorbed by immune cells and dramatically lowered allergic responses.

4:00 AM | Girocronologia delle stelle simili al Sole
Definire una stella di tipo solare è alquanto complicato analogamente al caso dei pianeti di tipo terrestre. Un gemello del Sole dovrebbe avere una temperatura, massa e spettro simile alla nostra stella. Inoltre, anche in termini di età ci aspettiamo che esso abbia almeno 4,5 miliardi di anni. Ad ogni modo, determinare l’età di una […]

12:45 AM | El Niño Project (Part 6)
guest post by Steven Wenner Hi, I’m Steve Wenner. I’m an industrial statistician with over 40 years of experience in a wide range applications (quality, reliability, product development, consumer research, biostatistics); but, somehow, time series only rarely crossed my path. Currently I’m working for a large consumer products company. My undergraduate degree is in physics, […]

11:28 PM | Uncertain Dots 19
In which our hangout turns nineteen; we may need to look into a special guest for the 20th, or something. Or maybe save guest stars for the one after that, when it can drink. Anyway, Rhett and I chat about grading, lab reports, why Excel sucks, and an online experiment that we really ought to…

9:21 PM | Long Delay Echos A Radio Propagation Mystery
Picture 1 is taken from Villard's report[5] on long delay echoes (LDEs)There's lots of science out there still to be done, even in age old hobby of ham radio.  In one of my recent posts, I talked about Operation Smoke Puff, and experiment that bounced radio signals off a man-made cloud of ions to a distant receiver.  The project was sponsored by the military with hopes of being able to provide longer distance radio communications by creating a made-to-order skip path. As it turns out, […]

9:20 PM | “I’m busy” is a euphemism
I’ve read a couple articles about how we all get caught up in being so busy.  A lot of them talk about how we need to escape the busyness spiral.  Xykademiqz expressed frustration with people who are always busy. I guess I’m coming at it from a different angle. I’ve come to realize that the phrase […]

8:53 PM | Watch the Falcon 9 make a soft landing in the ocean!
After heavy seas swamped out a previous attempt to record video of a Falcon 9 test-landing in the Atlantic Ocean, SpaceX today released video of this month's trial.  After launching a series of satellites for ORBCOMM, the first stage of the rocket turned its engines back on for a controlled descent back to the surface.  The video, seen below, picks up partway through this return.  Once reaching the surface, the Falcon 9 gently touches down before tipping over into the sea.

7:24 PM | Microscopy charges ahead
Polarization charges in ferroelectric materials are screened by equal amounts of surface charges with opposite polarity under ambient conditions. Researchers have shown that scraping, collecting, and quantifying surface screen charges reveals the underlying polarization domain structure at high speed, a technique dubbed charge gradient microscopy (CGM).

2:43 PM | Gods, phylosophy and computers
by @ulaulaman http://t.co/Q3AODpvKAs #Godel #ontologicalproof #god #computer The ontological arguments for the existence of God was introduced for the first time by St. Anselm in 1078: God, by definition, is that for which no greater can be conceived. God exists in the understanding. If God exists in the understanding, we could imagine Him to be greater by existing in reality. Therefore, God must exist.There are a lot of phylosophies, mathematics and logicians that proposed their ontological […]

…there was a spacecraft called Rosetta. Rosetta had been traveling in space for 10 years, towards a comet called 67P/Churyumov-Gerasimenko. In time, Rosetta was able to see the comet in the distance, there was only a little way to go now… Launched in March 2004, the European Space Agency’s Rosetta spacecraft is just two weeks […]
