5:21 PM | Voyager has hit interstellar space…. maybe?
Poor Voyager, he just can’t catch a break. We’ve said it’s hit interstellar space more times than we want to admit and in 2012, the Voyager mission team announced that […]

10:54 AM | Physics Law Helps Explain Evolution of Passenger Airplanes
A new study, published in the Journal of Applied Physics, uses a now-famous law of physics called the Constructal law to witness the evolution of airplane designs over time and predict the future of aerospace design. One of the traditional arguments against Darwinian evolution has been that no one can confirm the process exists because [...]

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 [...]

2:45 AM | What happens when the largest objects meet their twins? (Synopsis)
“Art has a double face, of expression and illusion, just like science has a double face: the reality of error and the phantom of truth.” -Publilius Syrus Out in the depths of space, objects range from the incredibly small and low mass to the huge and super-heavy, shrinking down again for the most ultra-massive objects…

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…

4:30 PM | Casimir Effect And Boosting The Force Of Empty Space
A vacuum - empty space - is not as empty as one might think. In fact, empty space is a bubbling soup of various virtual particles popping in and out of existence – a phenomenon called "vacuum fluctuations". Usually, such extremely short-lived particles remain completely unnoticed, but in certain cases vacuum forces can have a measurable effect. A team of researchers have proposed a method of amplifying these forces by several orders of magnitude using a transmission line, channeling […]

2:25 PM | True And False Discoveries: How To Tell Them Apart
Many new particles and other new physics signals claimed in the last twenty years were later proven to be spurious effects, due to background fluctuations or unknown sources of systematic error. The list is long, unfortunately - and longer than the list of particles and effects that were confirmed to be true by subsequent more detailed or more statistically-rich analysis. read more

The beaches at Cornwall in England are beautiful, majestic ... and the repository for some seriously weird plastic garbage. For years, Lego pieces with nautical themes have been washing up on these shores. But why?Read more...

5:30 PM | New 'Quantum Bounce' Theory Explains How Black Holes Become White
Some cosmologists speculate that black holes end their lives by transforming into their exact opposite — so-called 'white holes ' that pour all the material they gobbled up back into space. A new theory based on quantum gravity could explain how this is possible.Read more...

5:27 PM | Watching Electrons Jump Between The Fragments Of Exploding Molecules
Ultra-short X-ray flashes have enabled scientists to watch electrons jumping between the fragments of exploding molecules. The study reveals up to what distance a charge transfer between the two molecular fragments can occur, marking the limit of the molecular regime. The technique used can show the dynamics of charge transfer in a wide range of molecular systems. Such mechanisms play a role in numerous chemical processes, including photosynthesis.read more

10:39 AM | The meaning of exponential | Jon Butterworth | Life & Physics
Why populations explode, and why traces of radioactive elements can hang around for a very long timeExponential increases, and decreases, pop up quite often in various contexts. The word is generally used as an impressive adjective to imply something happening really fast and getting faster. This isnt always sensible. In fact exponential decreases start fast and get slower, hence the problem with radioactive waste hanging around for ages. Continue reading...

11:00 AM | A Universal Solution For A Quantum Three-Body Problem
Have physicists conquered the scaling behavior of exotic giant molecules?When a two-body relation becomes a three-body relation, the behavior of the system changes. The basic physics of two interacting particles is well understood but the mathematical description of a three- or many-body system becomes so difficult that calculating the dynamics can blast the capacities of even modern super computers. Under certain conditions, the quantum mechanical three-body problem may have a universal […]

9:00 AM | Flying an Airplane isn’t Rocket Science. Wait…
FromTheLabBench note: My little sister Angie (a to-be undergraduate student at the University of Vermont) recently flew an airplane ALL BY HERSELF. If some of my readers don't know this about me, I am terrified of airplanes. So as soon as I heard she had landed safely, I did the first thing you'd expect me to do. I asked her to write a guest blog post here! “Are you good to go? No questions?” My flight instructor, Ron, asks me... Read more
