8:38 AM | $1M grant to develop an ultra-compact X-ray free electron laser
Such a device could be used for ultra-high-speed and high-resolution imaging in chemistry, biology, materials science and condensed matter physics. For example, in the life sciences, one could view images with resolutions clear enough to see individual carbon atoms, or to discern events such as a chemical reactions that last one quadrillionth of a second or shorter.

8:00 AM | Information Aversion
  Why do ostriches stick their heads under the sand when they’re scared? They don’t. So why do people say they do? A Roman named Pliny the Elder might be partially to blame. He wrote that ostriches “imagine, when they have thrust their head and neck into a bush, that the whole of their body […]

7:00 AM | L’influenza della rotazione planetaria sull’abitabilità
Esistono quasi 2000 esopianeti confermati anche se la maggior parte di essi sono giganti gioviani che presentano ambienti decisamente inospitali. Nonostante ciò, la missione del satellite Kepler ha permesso di identificare una manciata di pianeti rocciosi, più piccoli, che sono presenti nella cosiddetta zona abitabile e, forse, potrebbero ospitare ambienti più adatti allo sviluppo di […]

6:46 AM | Throwback Thursday
OK, the photo above is a recent picture of me– yesterday, in fact. But the spiral-carved rock I’m standing next to was carved that way a bit more than five thousand years ago, so that ought to count as a throwback… We’ve been in Dublin the last few days, and on Thursday we took a…

8:08 PM | Shaping the future of nanocrystals (w/video)
Researchers have recorded the first direct observations of how facets form and develop on platinum nanocubes in solution, pointing the way towards more sophisticated and effective nanocrystal design and revealing that a nearly 150 year-old scientific law describing crystal growth breaks down at the nanoscale.

6:49 PM | Astroboy: Black Looks
Se vi fosse al mondo un unico e solo luogo ove riposare e trovare pace, quel luogo sarebbe, per ciascuno di noi, sulle ginocchia della propria madre.Bellissima: mistero, azione, gag, suspance. Il tema del razzismo. Il tema della perdita. La ricerca delle proprie radici. La ricerca delle risposte alle proprie domande, ai dubbi della vita. La risposta al dolore con altrettanto dolore e violenza, con l'intolleranza verso chi si percepisce diverso.Black Looks, infatti, consente a Tezuka di […]

3:20 PM | Physicists have chilled the world's coolest molecules
Yale physicists have chilled the world's coolest molecules. The tiny titans in question are bits of strontium monofluoride, dropped to 2.5 thousandths of a degree above absolute zero through a laser cooling and isolating process called magneto-optical trapping.

2:00 PM | Subatomic Physics in Your Medicine Cabinet
Aspirin’s Form I has a structure that is more robust all-around, whereas Form II is strongest along one axis and weaker on others, making the second version less stable.Scientists in Berlin have just cracked the case on a recently-raised question about one of the world’s most popular medicines: aspirin. By taking into account previously-overlooked forces, which only have significant effects at distances not much greater than the size of an atom, the team was able to explain why […]

1:55 PM | Magnet Water Flow Good and Channels Linear: Lab Book 2014_08_20
Summary:  Longer spectrum runs were performed on each of the available low energy sources.  The channel vs. energy graph was re-plotted based on the new data.  The behavior is still linear.  The only issue at the moment, is that the signal levels are close to the noise count levels, causing the peaks from each of the sources to be fairly broad.  This should be OK.  since we're just looking for evidence of a signal at all, resolution won't be critical in this […]

1:48 PM | Guidelines for enhancing solar cells using surface plasmon polaritons
Researchers from NIST have established guidelines for using surface plasmon polaritons (SPPs) to improve absorption in both photovoltaic or photoelectrochemical cells used for energy conversion. In both types of photocells, SPPs have the potential to increase the amount of light absorbed in the active material layer, improving the overall efficiency of light collection in solar energy devices.
