NANO TECH Molecules pass through nanotubes at size-dependent speeds

Like a pea going through a straw, tiny molecules can pass through microscopic cylinders known as nanotubes. This could potentially be used to select molecules according to size - for example, to purify water by allowing water molecules to pass through while bl... more

TIME SPACE Super-bright stellar explosion is likely a dying star giving birth to a black hole or neutron star

Now an MIT-led team has found strong evidence for the signal's source. In addition to a bright optical flash, the scientists detected a strobe-like pulse of high-energy X-rays. They traced hundreds of millions of such X-ray pulses back to the Cow, and found th... more

CHIP TECH Rough surface could keep small electronic parts from sticking together

When a piece of gift-wrapping tape sticks to itself, it's frustrating, but when small parts in a microgear or micromotor stick together, an electronic device may not work well, if at all. Scientists now report in the journal ACS Applied Materials and Interface... more

CHIP TECH Enabling 'internet of photonic things' with miniature sensors

The photonic sensors recorded data during the spring of 2017 under two scenarios: one was a real-time measurement of air temperature over 12 hours, and the other was an aerial mapping of temperature distribution with a sensor mounted on a drone in a St. Louis ... more

TECH SPACE The first laser radio transmitter

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences transmitted a recording of Martin's classic "Volare" wirelessly via a semiconductor laser - the first time a laser has been used as a radio frequency transmitter. In a pape... more

ENERGY TECH New technology could wean the battery world off cobalt

But now, a research team led by scientists at the University of California, Berkeley, has opened the door to using other metals in lithium-based batteries, and have built cathodes with 50 percent more lithium-storage capacity than conventional materials. "We'v... more

TIME SPACE Measuring quantum systems with compressive sensing

In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be simultaneously measured precisely. Recently, researchers have been d... more

CHIP TECH Rice-sized laser, powered one electron at a time, bodes well for quantum computing

Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or "maser," is a demonstration of the fundamental interactions between light an... more
