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)

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, Sanghyuk Moon)

“As NASA continues to push the boundaries of human imagination and innovation, we have seen the value in utilizing a citizen-based professional crowd to complement our internal efforts and solve complex real-world challenges,” Jason Crusan, director of NASA’s Tournament Lab.

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)

This artist’s concept illustrates a supermassive black hole with millions to billions times the mass of our sun. Supermassive black holes are enormously dense objects buried at the hearts of galaxies. (Credit: NASA/JPL-Caltech)

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)

Chu says worker feedback from the trial has been mostly positive. Testers were pleased that the exoskeleton let them lift heavy objects repeatedly without strain, but everyone also wanted it to move faster and be able to cope with heavier loads. (Credit: Daewoo)

This is a schematic of the process to localize NV centers in 3-D. The researchers blasted carbon ions through holes to create vacancies and heated the diamond to make the vacancies mobile within the crystal. NV centers could form in the nitrogen-doped layer below where the holes were placed. (Credit: F.J. Heremans and D. Awschalom/U. Chicago and K. Ohno/UCSB)

Map showing Ceres and Vesta as they approach each other closely this coming week. Both asteroids are near the easy-to-find star Zeta in Virgo not far from bright Mars. Although the asteroids appear very close together in the sky, they’re really about 51 million miles apart with Vesta in the foreground. (Credit: Chris Marriott’s SkyMap)
By filtering light from the sun, CQT researchers have made a strong detection of a quantum effect known as ‘photon bunching’ in its light. This is a hallmark of the sun radiating like a black body. (Credit: NASA/SDO)

Mechanical oscillators translate an applied force into measurable mechanical motion. The Standard Quantum Limit is imposed by the Heisenberg uncertainty principle, in which the measurement itself perturbs the motion of the oscillator, a phenomenon known as “quantum back-action.” (Credit: Kevin Gutowski)
