For Better Science

Math educator Grant Sanderson, creator of 3Blue1Brown, argues that now is an exceptionally good time to go into mathematics, in a newly released video. His claim comes amid surging interest in the field driven by machine learning, data science and other quantitative careers. Online commenters are debating whether opportunities for mathematicians have genuinely never been better, with many pointing to AI research and industry demand.

Researchers report an engineered hydrogel that separates a material's mechanical strength from its bone-building biological activity, meaning stiffness and bone regeneration can now be tuned independently. The development could allow implants or scaffolds to be designed for load-bearing support without forcing compromises in biological performance, a long-standing trade-off in bone tissue engineering.
