Proof confirmed of 400-year-old fruit-stacking problem

Now, a mathematician has announced the completion of an epic quest to formally prove the so-called Kepler conjecture. “An enormous burden has been lifted from my shoulders,” says Thomas Hales of the University of Pittsburgh, Pennsylvania, who led the work. “I suddenly feel ten years younger!” (Credit: Ray Tang/Rex)

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)

High-energy particle collisions reveal the unexpected

High-energy collisions between nuclei (white arrows) produce a cloud of elementary particles including quarks (red) and gluons (yellow). When gluons form an expansion front, they can produce a wall of matter called a color glass condensate, which eventually dissipates as the expansion continues.

Lonely supernovae may have been kicked out of their galaxies

Whovian physicists claim TARDIS time travel is possible

While time travel may be theoretically possible, there are unfortunately several drawbacks to the researchers’ TARDIS concept. In order to function, it requires the use of exotic matter, which has yet to be shown to exist in our universe. Time travel would also have to violate classical mechanics, and in order to move in anything other than a circular direction in both time and space, more than one TARDIS curve would need to be constructed, raising the possibility of exiting the time vortex into a universe of anti-matter.

Nature’s magnifying glass: Gravitational lensing

A typical magnifying glass works by bending light (i.e. refraction) to a focus point, in this case your eye. In a similar way, gravitational lensing also works by bending light, but in this case it is mass from another galaxy bending the light. This galaxy that extends far into space causes light rays passing near and through its gravitational field to bend and again refocus onto a particular location. The more massive and dense the matter, the more bending and refracting. (Credit: Flickr, Hubble Heritage)

Baby universe picture brought closer to theory

 The anisotropies of the Cosmic microwave background (CMB) as observed by Planck. The CMB is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380 000 years old. It shows tiny temperature fluctuations that correspond to regions of slightly different densities, representing the seeds of all future structure: the stars and galaxies of today.
