The Hubble and James Webb Space Telescopes have revealed thousands of young star clusters emerging from their birth clouds. The observations, published in Nature Astronomy, show that more massive clusters clear away their natal gas faster than lower-mass clusters. The result has important implications for our understanding of star formation and how the young stars affect their surroundings.

Concordia researchers developed a high-fidelity CPR simulator that replicates blood flow in reduced gravity, using a mannequin with a 3D-printed cardiovascular system. Tests in parabolic flights showed it reproduces realistic pressure patterns while revealing key differences in blood flow under hypogravity, helping improve CPR techniques for future space missions.

Using the James Webb Space Telescope, astronomers measured the composition of a mini-Neptune inside the orbit of a hot Jupiter. They say this highly unusual planetary system probably formed out beyond its star’s “frostline,” in the colder region of the system’s early disk of protoplanetary material.

Are we ready for solar storms, submarine cable cuts, satellite disruptions, and extreme weather to disrupt communication networks and potentially trigger a “digital pandemic"?

A new report – “When digital systems fail: The hidden risks of our digital world​" – outlines risk scenarios on Earth, at sea, and in space, analysing the fragility of interconnected digital systems and offering a roadmap for preparedness.

Experts brought together by the International Telecommunication Union (ITU), the United Nations Office for Disaster Risk Reduction (UNDRR), and Sciences Po, call for coordinated action between countries to improve digital resilience and protect essential services like healthcare, finance, and emergency response.
