Every parking spot at the International Space Station is currently occupied

Here’s an awesome photo to start your day: The International Space Station currently has five spacecraft docked to it — the most that can be currently attached. If any of the world’s space agencies, or private companies like SpaceX were to send up another spacecraft today, they’d need to circle until another parking space becomes available. (Credit: NASA)

Planck’s early universe exploration ‘great landmark’ in human history

“This piece of information, that has always been a dream, and never was thought of as being within human grasp. But here in the year 2014 on finds that perhaps this mission is going to be telling us how the universe started,” said Harwit, who is an expert in infrared astronomy and works as a member of the ESA’s Submillimeter Wave Astronomical Satellite, as well as on the Herschel Telescope.

Are processors pushing up against Moore’s Law and the limits of physics?

Plot of CPU transistor counts against dates of introduction. Note the logarithmic vertical scale; the line corresponds to exponential growth with transistor count doubling every two years. Transistor counts for integrated circuits plotted against their dates of introduction. The curve shows Moore's law - the doubling of transistor counts every two years. The y-axis is logarithmic, so the line corresponds to exponential growth. (Credit: Wgsimon)

The smallest possible scale in the universe

Every once in a while I think that there maybe is no fundamentally smallest unit of length; that all these arguments for its existence are wrong. I like to think that we can look infinitely close into structures and will never find a final theory, turtles upon turtles, or that structures are ultimately self-similar and repeat.(Credit: Sabine Hossenfelder)

Beyond six nines: Ultra-enriched silicon paves the road to quantum computing

NIST researcher Kevin Dwyer with the silicon enrichment apparatus. The process begins at the left, where natural-abundance silicon in the form of silane gas (SiH4) is ionized. The ions pass through a magnetic field (top left), which causes their paths to curve to different degrees based on their mass. The silicon-28 ions, now separated from the other silicon isotopes, are decelerated through an ultra-high vacuum chamber (top center) and into the deposition chamber (top right) (Credit: Pomeroy, NIST, Dwyer)

 From eons to seconds, proteins exploit the same forces

A protein folding funnel, the product of algorithms created by Rice’s Center for Theoretical Biological Physics, is a graphic representation of the energy landscape a protein navigates as it goes from its initial floppy state to a folded, functional unit. The funnel shows smooth slopes as well as outcroppings where parts of a protein may pause while others catch up, and also traps that could cause a protein to misfold. New Rice research shows how the interplay between evolution and physics developed the skills necessary to conserve useful proteins. (Credit: Center for Theoretical Biological Physics/Rice University)

3-D codes yield unprecedented physics, engineering insights

Sandia National Laboratories researchers Steve Plimpton, left, and Michael Gallis look at a projection of a model of the Russian MIR space station, which fell out of orbit several years ago and disintegrated, with the remains ending up at the bottom of the Indian Ocean. Using Sandia’s 3-D code SPARTA, the calculation is simulating an instance of the process of de-orbiting. (Credit: Randy Montoya)

The summer’s second Supermoon to return Sunday afternoon

A perigee moon rises in Washington, DC, on March 19, 2011. A perigee moon is visible when the moon's orbit position is at its closest point to Earth during a full moon phase. The full moon coincided with its closest approach to the Earth, 221,565 miles (356,575 km), making the so-called "super moon" look slightly larger than average.
