Teslaphoresis-activated self-assembling carbon nanotubes look even cooler than they sound

Posted by in categories: materials, nanotechnology

Circa 2016


Not all important scientific research is cool looking, or has a cool name. But now and then you get something with both. These self-assembling carbon nanotubes are created with a process called Teslaphoresis. If you’ve read a more impressive-sounding sentence today, I’d like to hear it.

Even the lab of Rice University chemist Paul Cherukuri looks like a proper mad scientist’s lair. But don’t let the flashy trappings fool you: this is a very significant development.

This Camera Captures the Speed of Light

Posted by in categories: electronics, particle physics

Circa 2011


Scientists at M.I.T’s Media lab have created a camera that can capture the speed of light, taking a photo in less than two-trillionths of a second. Using multiple cameras, sensors, a pulse light source and mirrors, the researchers create slow motion movies of light moving through objects and liquids. They call the technique femto-photography. “We have built a virtual slow motion camera where we can see photons, or light particles through space,” said Associate Professor Ramesh Raskar in an video interview. “Photons travel about a million times photons travel a million times faster than bullets. So our camera can see photons, or bullets of light traveling through space.”

Jurrassic Park got it wrong: Research indicates raptors didn’t hunt in packs

Posted by in category: entertainment

A new University of Wisconsin Oshkosh analysis of raptor teeth published in the peer-reviewed journal Palaeogeography, Palaeoclimatology, Palaeoecology shows that Velociraptors and their kin likely did not hunt in big, coordinated packs like dogs.

The raptors (Deinonychus antirrhopus) with their sickle-shaped talons were made famous in the 1993 blockbuster movie Jurassic Park, which portrayed them as highly intelligent, apex predators that worked in groups to large prey.

“Raptorial dinosaurs often are shown as hunting in packs similar to wolves,” said Joseph Frederickson, a vertebrate paleontologist and director of the Weis Earth Science Museum on the UWO Fox Cities campus. “The evidence for this behavior, however, is not altogether convincing. Since we can’t watch these dinosaurs hunt in person, we must use indirect methods to determine their behavior in life.”

Flying Around the World in a Solar Powered Plane

Posted by in categories: solar power, sustainability, transportation

The journey took a very long time—505 days to fly 26,000 miles (42,000 km) at an average speed of about 45 mph (70 kph)—but pilots Bertrand Piccard and Andre Borschberg successfully landed the Solar Impulse 2 aircraft in Abu Dhabi on Tuesday, after flying around the world using only the power of the Sun. Solar Impulse 2 is a solar-powered aircraft equipped with more than 17,000 solar cells that weighs only 2.4 tons with a wingspan of 235 ft (72 m). Technical challenges, poor flying conditions, and a delicate aircraft all contributed to the slow pace. Gathered here are images from the record-setting circumnavigation, undertaken to help focus the world’s efforts to develop renewable energy sources.

Quantum clocks and the temporal localisability of events in the presence of gravitating quantum systems

Posted by in categories: quantum physics, space

The standard formulation of quantum theory relies on a fixed space-time metric determining the localisation and causal order of events. In general relativity, the metric is influenced by matter, and is expected to become indefinite when matter behaves quantum mechanically. Here, we develop a framework to operationally define events and their localisation with respect to a quantum clock reference frame, also in the presence of gravitating quantum systems. We find that, when clocks interact gravitationally, the time localisability of events becomes relative, depending on the reference frame. This relativity ia a signature of an indefinite metric, where events can occur in an indefinite causal order. Even if the metric is indefinite, for any event we can find a reference frame where local quantum operations take their standard unitary dilation form. This form is preserved when changing clock reference frames, yielding physics covariant with respect to quantum reference frame transformations.
