Russian Nobel physics winner Alferov dies at 88

Russian scientist Zhores Alferov, who won the Nobel physics prize for his work in semi-conductor and laser technologies, has died, agencies said on Saturday. He was 88.

New X-ray measurement approach could improve CT scanners

A new measurement approach proposed by scientists at the National Institute of Standards and Technology (NIST) could lead to a better way to calibrate computed tomography (CT) scanners, potentially streamlining patient treatment by improving communication among doctors.

A high-precision test bench for LISA technology

For the first time, it has been possible to test laser measurement technology for LISA in laboratories almost under mission conditions. A team of researchers led by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute; AEI) and the Institute for Gravitational Physics at Leibniz Universität in Hannover, Germany, achieved the breakthrough with a novel experiment. The work ties up with the LISA Pathfinder mission, which tested LISA technologies in space from 2015 to 2017.

Promising far-infrared detectors better protected against cosmic rays

Astronomers need ever more sensitive detectors to broaden their understanding of the universe. Microwave kinetic inductance detectors (MKID) could make far-infrared telescopes 1 million times more sensitive. Scientists from SRON Netherlands Institute for Space Research and TU Delft have now taken a step toward the development of these detectors by protecting them against harmful cosmic rays. Publication in Applied Physics Letters.

Scientists learn how to manage the properties of amorphous microwires

Amorphous ferromagnetic microwires are thin, glass-coated wires used to manufacture magnetic safety tags and in medicine. A team of physicists from Immanuel Kant Baltic Federal University and MISIS controlled their properties by adjusting internal mechanical stress. Their article was published in the Journal of Magnetism and Magnetic Materials.

Large Hadron Collider pushing computing to the limits

At the end of 2018, the Large Hadron Collider (LHC) completed its second multi-year run ("Run 2") that saw the machine reach a proton–proton collision energy of 13 TeV, the highest ever reached by a particle accelerator. During this run, from 2015 to 2018, LHC experiments produced unprecedented volumes of data with the machine's performance exceeding all expectations.

A polka-dot pattern appears in superfluid helium-3 in a thin cell when exposed to a magnetic field

A team of researchers from Royal Holloway University of London and Cornell University has found that a polka-dot pattern emerges in superfluid helium-3 when it is placed in a thin cavity and subjected to a magnetic field. They have published their findings in the journal Physical Review Letters.

A trap for positrons

For the first time, scientists from the Technical University of Munich (TUM) and the Max Planck Institute for Plasma Physics (IPP) have succeeded in losslessly guiding positrons, the antiparticles of electrons, into a magnetic field trap. This is an important step toward creating a matter-antimatter plasma of electrons and positrons like the plasmas believed to occur near neutron stars and black holes. In an interview, Dr. Eve Stenson presents her research work.

Solid state thermochemiluminescence achieved with crystals

Researchers have developed macroscopic organic crystals that emit light when heated, a process referred to as thermochemiluminescence that was previously reported only in solution.

The hipster effect: Why anti-conformists always end up looking the same

You've probably seen this effect—perhaps you are a victim of it. You feel alienated from mainstream culture and want to make a statement that you are not part of it. You think about wearing different clothes, experimenting with a new hairstyle, or even trying unconventional makeup and grooming products.
