4:19 PM | New method to attack cancer at its genetic source
MicroRNAs may be tiny — as few as 20 genetic letters, compared to 3 billion in the DNA of a human — but they play a major role in biology, […]

4:16 PM | New model clarifies photoexcited thin-film lattice dynamics
No comprehensive study has yet been carried out to characterize the photoexcited lattice dynamics of an opaque thin film on a semi-infinite transparent substrate. As a result, ultrafast X-ray diffraction data for such samples can be challenging to interpret. Now a new study builds a model to help interpret such data.

4:15 PM | Reaching New Heights For Women & X-ray Astronomy
PART 2: #sts93 (PART 1) Preparation for Launch The size and weight distribution of the Chandra X-ray Observatory and its booster (called the Inertial Upper Stage, or IUS) posed extra risks for the crew of STS-93. Space Shuttle Columbia was the heaviest shuttle and the bulk of the weight from the two components in the payload bay – the heaviest ever to fly -- was located in the aft of the Shuttle. This meant it could be extremely dangerous – or fatal -- if for some reason, they […]

2:50 PM | Return of the Revenge of the Project for Non-Academic Science
I’ve been doing a lot of darkness-cursing lately (mostly off-line), so we could stand to have a little candle-lighting. It’s been a few years since I last did a round of profiles of scientists outside academia, so let’s see if that will fly again… So, if you 1) Have a degree in a STEM field…

10:24 AM | Novel nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging
MIT chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging in living animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor?s environment, or determine whether drugs have successfully reached their targets.

9:56 AM | Nanotechnology in the 'green' economy - opportunities and risks
A new review article examines opportunities and practical challenges that nanotechnology applications pose in addressing the guiding principles for a green economy. There is a general perception that nanotechnologies will have a significant impact on developing 'green' and 'clean' technologies with considerable environmental benefits. The associated concept of green nanotechnology aims to exploit nanotech-enabled innovations in materials science and engineering to generate products and […]

4:51 AM | Vignette (The Best Foreseeble Ending)
Given his character, their “love story for the ages” would honestly have ended a few chapters in, and very badly. But what would have happened after that? “The officer outside said it looks like an accident.” “Yes, well, any time a person dies not under a doctor’s care, my department gets involved. Usually it just […]

4:00 AM | Una nuova teoria sugli universi paralleli ‘interagenti’
Un gruppo di ricercatori della University of Griffith stanno sfidando le regole fondamentali della teoria dei quanti proponendo una nuova e più radicale teoria basata su universi paralleli “interagenti”. In un articolo pubblicato su Physical Review X, Howard Wiseman e Michael Hall del Centre for Quantum Dynamics, assieme a Dirk-Andre Deckert della University of California a […]

2:46 AM | The Elementals, by Michael McDowell
Michael McDowell’s reprinted 1981 novel The Elementals conclusively answers a question that I’ve been wondering for years: why are there so few classic haunted house stories?  I’ve always been a fan of such stories, or more generally “old dark house” … Continue reading →

11:03 PM | The internet makes me impatient
I really, really needed to get ahold of a book.  I looked at all three libraries I have access to.  One has a hard copy, but it’s a couple hours away so getting it would be tough (to say the least).  The second library said it was available online, but apparently the institutional subscription doesn’t […]

9:57 PM | Art More Beautiful Than Fiction
"Poof!" goes a star, leaving its new dust to interact as it will.  Ever wonder what solar systems may look like before those clouds of dust coalesce to form the clumps we call planets? Sometimes those who know the science + data can visualize things in a special way. [Enter astronomers.] Here's NASA's new artistic visualization of the actual planetary system austerely named "HD 95086."Image Illustration Credit: Spitzer Space Telescope, JPL, NASASource page: NASA's APOD-----Share this […]

9:36 PM | Billions of nanoreactors inform materials design
Imagine building a chemical reactor small enough to study nanoparticles a billionth of a meter across. A billion times smaller than a raindrop is the volume of an E. coli cell. And another million times smaller would be a reactor small enough to study isolated nanoparticles. Add to that the challenge of making not just one of these tiny reactors, but billions of them, all identical in size and shape. Researchers at Cornell have done just that.

9:27 PM | Ancient Meteorite Reveals New Evidence On The Solar System's Beginnings
Originally published: Nov 13 2014 - 2:00pm, Inside Science News ServiceBy: Charles Q. Choi, Contributor(Inside Science) -- An ancient meteorite has now yielded the first physical evidence that intense magnetic fields played a major role in the birth of our solar system.Shortly after the sun formed about 4.6 billion years ago, a rotating disk of gas and dust that surrounded the newborn star coalesced into the planets that children now memorize. Astronomers peering at young distant stars find […]

5:20 PM | Researchers synthesize new form of silicon for solar applications
Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices - carbon is to biology as silicon is to technology. A team of scientists has synthesized an entirely new form of silicon, one that promises even greater future applications.
