Laboratory Equipment has more on the Helmholz coil (a bit of antique lab machinery) and how one of its strange qualities might help Sandia’s “Z machine” fusion experiment create the pollution-free power of tomorrow:

A Helmholz coil produces a magnetic field when electrified. In recent experiments, two Helmholz coils, installed to provide a secondary […]

This is where European scientists work on experiments for the Compact Muon Spectrometer and Atlas, the project that found the Higgs boson.

Which is to say, smart people do cool things with very, very small pieces here.

I can’t even begin with this one. But yes, researchers at the Czech University of Agriculture have determined that dogs orient themselves to magnetic north when excreting:

We measured the direction of the body axis in 70 dogs of 37 breeds during defecation (1,893 observations) and urination (5,582 observations) over a two-year period. After […]

One of a series of videos in which white-gloved technicians from the Florence Fondazione Scienza e Tecnica (Science and Technics Foundation) operate antique scientific equipment, demonstrating how the devices reveal the secrets of nature.

Quietly. Reverently. Meditatively. Efficiently.

BBC looks ahead to a brighter future… at least as far as our energy supply is concerned. Fusion reactors have gotten one small step closer, using lasers that zap hydrogen into heavier elements:

Now, a breakthrough by scientists at the National Ignition Facility (NIF) could boost hopes of scaling up fusion.

NIF, based at Livermore […]

FT.com introduces us to the genteel, cultured Fabiola Gianotti – accomplished pianist, paleontologist’s daughter, coffee enthusiast, trained classicist… and the kind of person who hunts the Higgs boson:

Nature is her ultimate inspiration, Gianotti says, and she explains how she inherited her love of it from her father, an Italian micropaleontologist. His work meant […]

PhysOrg gets non-linear with their look at “time reversal” and how we might soon use it:

Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable electronics, even […]

The Atlantic reveals the fluid dynamics of deadly mob disasters that shows how crowds can be so blindly powerful:

“It happens like magic,” says Dirk Helbing, a professor in Zurich, Switzerland, who studies sociology and crowd modeling. “People don’t have to think about it, you don’t need to have legal regulations or policemen to […]
