🌍🛰️ How do NRENs & RRENs support Earth Observation research?
At our April infoshare with the Group on Earth Observations (GEO), RedCLARA & ASREN, we explored how R&E networks enable Earth Observation research, supporting data access, policy, training, and cross-border collaboration.
Daniela Brauner also shared these insights at GEO Global Forum 2025 last week.

A composition-informed search for large-scale anisotropy with the Pierre Auger Observatory
The large-scale dipolar structure in the arrival directions of ultra-high-energy cosmic rays with energies above $8\,$EeV observed by the Pierre Auger Collaboration is a well-established anisotropy measurement. This anisotropy is understood to be of extragalactic origin, as the maximum of the dipolar component is located ${\sim}115^\circ$ away from the Galactic Center. Cosmic rays interact with background radiation and magnetized regions on their path from their sources to Earth. These interact…

I think the last time I bought a manga was in 2018ish. It was time to break the curse.

China has suspended almost all exports since April 4 of seven kinds of #rare #earth metals,
as well as very powerful magnets made from three of them.
The halt has caused increasingly severe shortages that threaten to close many factories in the United States and Europe.

What to Know About China’s Halt of Rare Earth Exports
Since early April, China has stopped almost all shipments of critical minerals that are needed for cars, robots, wind turbines, jet fighters and other technologies.

Physical properties of $R$Co$_{2}$Al$_{8}$ ($R=$ La, Ce, Pr, Nd and Sm) single crystals: an emerging structure-type for anisotropic Kondo lattice studies
Systematic investigations of rare-earth ($R$) based intermetallic materials is a leading strategy to reveal the underlying mechanisms governing a range of physical phenomena, such as the formation of a Kondo lattice and competing electronic and magnetic anisotropies. In this work, the magnetic, thermal and transport properties of $R$Co$_{2}$Al$_{8}$ ($R=$ La, Ce, Pr, Nd and Sm) single crystals are presented. LaCo$_{2}$Al$_{8}$ is characterized as a Pauli paramagnet and transport measurements, w…

Weekend #Plankton Factoid 🦠🦐
The new Surface Water and Ocean Topography (SWOT) satellite is crazy accurate. It can measure ocean altimetry to a mm, imaging internal waves and small sub eddies (rotating mixing zones). Tiny changes in height happen when water swirls (try it in a sink) with greater height at the edges due to centripetal force. These may be even more important for temperature &a…

The Highest-Energy Neutrino Event Constrains Dark Matter-Neutrino Interactions
Dark Matter-neutrino interactions affect the propagation of astrophysical neutrinos, attenuating the flux of neutrinos arriving at Earth. Using the highest-energy neutrino event detected to date by the KM3NeT collaboration as an example, and assuming an extragalactic origin, we derive limits on these interactions at $E_ν= 220^{+570}_{-110}\, \mathrm{PeV}$. Considering only the propagation on the Milky Way Dark Matter halo, we constrain the interaction cross section over the mass of the Dark Ma…

Classification of high energy muon bundles and single muons from the southern sky in IceCube
The IceCube Neutrino Observatory, located at the geographic South Pole, uses the glacial ice volume to detect astrophysical neutrinos. Detection of the neutrinos from the northern sky provides the opportunity to use a large effective volume. However, as the cross-section increases with energy, most high-energy neutrinos are absorbed by the Earth. On the other hand, probing down-going PeV neutrinos from the southern sky becomes challenging because of the large cosmic ray induced muon backgrounds…
