Life from Earth could temporarily survive on Mars
German Aerospace Center scientists. The researchers launched these small lifeforms into Earth's stratosphere, which replicates key characteristics of the Martian environment, and found that some microorganisms, in particular spores of black mold, survived the trip. This new way of testing endurance to space travel will be invaluable for understanding the threats and opportunities of microbes in future missions to Mars. (2021-02-22)

Research highlights ways to protect astronaut cardiovascular health from space radiation
In the inky blackness of space an invisible threat is ever present - radiation. It can have a huge array of negative effects on astronaut health, including cardiovascular disease. However, if we are ever to journey to the red planet, we will need to understand and reduce this risk. A new review charts a course through what we know about the cardiovascular risks of space radiation, and the best ways to protect space travelers. (2021-02-12)

Air-guiding in solid-core optical waveguides: A solution for on-chip trace gas spectroscopy
We demonstrate an air-suspended waveguide that exhibits exceptional field delocalization and an external field confinement of 107 %, providing a stronger interaction with the surrounding air than a free-space beam. Operating at mid-infrared wavelengths, the waveguide is an ideal building block of next-generation on-chip sensors for sensitive and specific trace gas detection by tunable diode laser absorption spectroscopy (TDLAS).

How do electrons close to Earth reach almost the speed of light?
In the Van Allen radiation belts, electrons can reach almost speed of light. Hayley Allison and Yuri Shprits, German Research Centre for Geosciences, have revealed conditions for such strong accelerations. They had demonstrated in 2020: during solar storm plasma waves play a crucial role. However, it remained unclear why ultra-relativistic electron energies are not achieved in all solar storms. In Science Advances they now show: extreme depletions of the background plasma density are crucial. (2021-02-02)

Hidden-symmetry-enforced nexus points of nodal lines in layer-stacked dielectric photonic crystals
The paper reveals that Maxwell's equations can have hidden symmetries induced by the fractional periodicity of the material tensor components and paves the way to finding novel topological degeneracies unique in photonics. The idea is exemplified by an AB-layer-stacked dielectric photonic crystal, where the unique photonic band connectivity leads to a new kind of symmetry-enforced triply degenerate points with exotic spin-1 conical diffractions at the nexuses of two nodal rings and a Kramers-like nodal line (2020-10-20)
