Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other classic features in the exoplanet population, such as the high abundance of small planets over large planets and a tendency for giant planets to only form around stars enriched in heavy elements such as oxygen, carbon and iron. The finding points toward two distinct pathways for forming small and large planets. 

Binary neutron star mergers emit gravitational waves followed by light. To fully exploit these observations and avoid missing key signals, speed is crucial. In a study to be published in Nature on March 5, 2025, an interdisciplinary team of researchers presents a novel machine learning method that can analyze gravitational waves emitted by neutron star collisions almost instantaneously – even before the merger is fully observed. A neural network processes the data and enables a fast search for visible light and other electromagnetic signals emitted during the collisions. This new method could be instrumental in preparing the field for the next generation of observatories.

Artificial Intelligence (AI) is poised to transform healthcare, but its successful integration into healthcare requires careful consideration of regulatory frameworks, governance structures, data equity, and privacy protections. To help their academic community coalesce around this challenge, a team comprised of researchers from Lehigh University, Massachusetts General Hospital/Harvard Medical School, and Northwestern University's Feinberg School of Medicine are gathering researchers, clinicians, and industry experts in this space as part of the 2025 Spring Symposium Series sponsored by the Association for the Advancement of Artificial Intelligence (AAAI.) The team's "Leveraging AI to Revolutionize Healthcare" symposium will be a key portion of the 2025 AAAI Spring Symposium Series, set for Monday, March 31 through Wednesday, April 2, 2025, at the San Francisco Airport Marriott Waterfront in Burlingame, California.

Chiba University proudly presents the International Workshop on Space Agriculture and Horticulture 2025, a groundbreaking event set to take place from March 9–11, 2025, at Matsudo Campus, Japan.

Bringing together leading researchers, industry pioneers, and space agencies—including NASA, the European Space Agency (ESA), and the German Aerospace Center (DLR)—this landmark workshop will explore the frontiers of space agriculture and horticulture.

The workshop aims to foster a deeper understanding of research initiatives across institutions worldwide, focusing on space horticulture, bioregenerative life support systems, and plant cultivation beyond Earth.

Through dynamic discussions and interdisciplinary collaboration, we seek to forge new pathways for future collaborative research, driving the next era of sustainable life in space.

We warmly welcome researchers, postgraduate students, industry professionals, and academic communities worldwide to join us in shaping the future of food production beyond our planet.
