Arecibo telescope receiver platform crashes onto dish
The telescope has been inoperable since mid-November, when multiple engineering companies reported that safety in and around it could not be guaranteed. Now their fears have come to pass. No one was injured.
Transportation of water into the deep Earth by Al-phase D
Researchers have recently measured the propagation speed of ultrasonic waves in an aluminum-rich hydrous mineral called Al-phase D at pressure conditions relevant to the Earth’s deep mantle. Their results suggest that seismic shear anomalies observed locally beneath subduction zones may reveal the presence of hydrous minerals in the uppermost lower mantle, which would have important implications for the Earth’s interior because hydrogen affects considerably the physical and chemical properties of mantle minerals.

Scientists warn of the social and environmental risks tied to the energy transition
(Universitat Autonoma de Barcelona) New international research by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) warns that green energy projects can be as socially and environmentally conflictive as fossil fuel projects. While renewable energies are often portrayed as being environmentally sustainable, this new study cautions about the risks associated with the green energy transition, arguing for an integrated approach that redesigns energy systems in favor of social equity and environmental sustainability.
