Jennifer Toes SESAME was officially inaugurated on 16 May 2017 (Image: CERN) The most recent issue of the Accelerating News newsletter has just been released, and is now available to view online. Issue 21 contains the following highlights: From...Show More Summary

Uncovering the connection between negative stiffness and magnetic domain walls

Nature doesn't like having interfaces—this is why bubbles like to be round, and the surface of a pond settles to flat as long as it's not disturbed. These trends minimize the total amount of interface (or surface) that is present. As...Show More Summary

Scientists create first laboratory generation of astrophysical shock waves

Throughout the universe, supersonic shock waves propel cosmic rays and supernova particles to velocities near the speed of light. The most high-energy of these astrophysical shocks occur too far outside the solar system to be studied in detail and have long puzzled astrophysicists. Show More Summary

New scales for the new kilogram

The Planck scale works according to the principle of electromagnetic force compensation: A weight force on one side of the scale is balanced by an electromagnetic force on the other side. This means that weights (so-called mass standards) will no longer be needed. Show More Summary

Super p-Brane Theory Emerging from Super Homotopy Theory

  A notorious open problem: What is the non-perturbative theory formerly known as Strings? We still have no fundamental formulation of “M-theory” – the hypothetical theory of which 11-dimensional supergravity and the five string theories are all special limiting cases. Show More Summary

Conference: 4 Oct 2017 - 6 Oct 2017, Bilbao, Spain.

Computer chip technology repurposed for making reflective nanostructures

A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.

Ultra-sensitive measurement of nanoscale deformation

Nanoscale deformations could impact the high-precision experiments, such as the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO)

Researchers offer new explanation for why protein fibers form

Alzheimer's disease results from a dysfunctional stacking of protein molecules that form long fibers inside brain cells. Similar stacking occurs in sickle-cell anemia and mad cow disease.

Heat-loving quantum oscillations

The rapidly developing science and technology of graphene and atomically-thin materials has taken another step forward with new research from The University of Manchester.

Controlling heat and particle currents in nanodevices by quantum observation

Researchers from the Theory Department of the MPSD have realized the control of thermal and electrical currents in nanoscale devices by means of quantum local observations.

Ultrafast motions and fleeting geometries in proton hydration

Basic processes in chemistry and biology involve protons in a water environment. Water structures accommodating protons and their motions have so far remained elusive. Applying ultrafast vibrational spectroscopy, researchers have mapped...Show More Summary

It Can be Done

For those interested in giving more people access to science, and especially those who act as gate-keepers, please pause to note that a primetime drama featuring tons of real science in nearly every episode can get 10 Emmy nominations. Show More Summary

Mark Zuckerberg goes live from Sanford Lab

More than 2 million people have viewed Zuckerberg’s Facebook Live video, which discusses DUNE, neutrinos and the search for dark matter.

Synopsis: Bacteria Never Swim Alone

Simulations and theory indicate that the “synchronized swimming” of bacteria occurs in much sparser suspensions of the microorganisms than expected. [Physics] Published Thu Jul 13, 2017

SLAC accelerator plans appear in Smithsonian art exhibit

The late artist June Schwarcz found inspiration in some unusual wrapping paper her husband brought home from the lab.   Leroy Schwarcz, one of the first engineers hired to build SLAC National Accelerator Laboratory’s original 2-mile-long linear accelerator, thought his wife might like to use old mechanical drawings of the project as wrapping paper.

Researchers develop technique to control and measure electron spin voltage

Information technologies of the future will likely use electron spin—rather than electron charge—to carry information. But first, scientists need to better understand how to control spin and learn to build the spin equivalent of electronic components, from spin transistors, to spin gates and circuits.

Type-II Dirac fermions spotted in two different materials

Experiments suggest the existence of a topological superconductor
