Researchers at the Institute for Bioengineering of Catalonia (IBEC) have recorded human embryo implantation in real time for the first time, using an innovative system developed in the laboratory that simulates the outer layers of the uterus in 3D. Implantation failure is one of the main causes of infertility, accounting for 60% of miscarriages. The work, published in the journal Science Advances, may help to better understand the mechanisms underlying the implantation process, improving fertility rates and optimising assisted reproduction processes.

One of the biggest challenges in cancer treatment is that certain cancers reappear after chemotherapy—and an aggressive type of blood cancer called acute myeloid leukemia (AML) is notorious for this. Now, new research from The Jackson Laboratory (JAX) points to a previously unknown molecular mechanism behind that chemoresistance, and a way to potentially disarm it.

Kyoto, Japan -- As space programs evolve and we continue to mistreat our own planet, human dreams of space tourism and planetary colonization seem increasingly common. However, features of spaceflight such as gravitational changes and circadian rhythm disruption -- not to mention radiation -- take a toll on the body, including muscle wasting and decreased bone density. These may even affect our ability to produce healthy offspring.

Studying the impact of spaceflight on germ cells -- egg and sperm precursor cells -- is particularly important because they directly influence the next generation, and any irreversible damage done to these will likely be transmitted to offspring. Previous examinations of embryonic stem cells that have undergone spaceflight have revealed abnormalities, but the exact cause of the damage has remained unknown.

This inspired a team of researchers at Kyoto University to test the potential damage to spermatogonial stem cells during spaceflight and the resulting offspring. The team utilized stem cells from mice, which have a much shorter reproductive life span than humans.

Media Invitation – IJCAI 2025, Montréal, Canada
Artificial Intelligence for a Better World – Since 1969

The 34th International Joint Conference on Artificial Intelligence (IJCAI) takes place August 16–22, 2025 in Montréal, Canada, bringing together over 2,000 AI researchers, practitioners, and thought leaders. Guided by the theme “AI at the service of society”, IJCAI 2025 features world-class keynote speakers, award-winning researchers, thematic tracks on AI for Social Good, Human-Centred AI, and AI, Arts & Creativity, as well as admission free public events like the AI Lounge: Between Wonder and Caution.

Highlights include talks by Yoshua Bengio, Heng Ji, Luc De Raedt, Bernhard Schölkopf, and IJCAI 2025 awardees Aditya Grover, Rina Dechter, and Cynthia Rudin. The program also showcases AI-driven competitions, an AI Art Gallery, and discussions on ethics, creativity, and global impact.
