Northwestern University engineers have created 3D-printed artificial neurons that can directly communicate with living brain cells, representing a significant advance toward brain-machine interfaces and more energy-efficient computing hardware inspired by the brain.^[1]

Northwestern University researchers have developed a fuel cell that uses microbes naturally present in soil to generate electricity. The device can power underground sensors for agriculture without needing batteries or solar panels.^[2]

Researchers have found that melamine cleaning sponges, often called "magic erasers," shed tiny plastic fibers as they break down during use. Scientists estimate these sponges could release over a trillion microplastic fibers per month globally.^[3]

James Webb Space Telescope observations have revealed the most compelling evidence yet for the universe's first stars—ancient "Population III" stars found clustered around a companion object that formed just 400 million years after the Big Bang.^[4]

The Hubble Space Telescope has captured a new image of IC 486, a barred spiral galaxy swirling through deep space. The image reveals the structure common to about two-thirds of all observed spiral galaxies.^[5]

A sungrazer comet designated C/2026 A1 (MAPS), discovered in early 2026, passed extremely close to the sun this month and may become visible from the Northern Hemisphere in the evening sky if it survived its close solar passage.^[6]

The 2026 Spring K-Royal Culture Festival, South Korea's largest national heritage celebration, will open on April 24 at Gyeongbokgung Palace in Seoul. The 10-day event marks its 12th year showcasing the country's royal palaces and cultural heritage.^[7]
