Paint it black(er): A new way to make cars darker than ever

18 June 2026 at 16:00
Scientists have developed a practical way to make ultra-black coatings to meet demand for trendy, luxury vehicles in China. The coating, described in a paper published in Matter & Light, is made up of a composite of carbon black pigment and carbon nanotubes. The resulting color is a deep jet black that also meets automotive standards, opening the door for car manufacturers to develop distinguished, high-end models in darker-than-ever hues.

Electric 'nose' can smell when your food's gone bad

17 June 2026 at 21:20
Most of us have used the sniff test to decide whether a slightly expired bottle of milk or a week-old box of takeout is still good to eat. But while the human nose can be quite astute, it doesn't always catch everything. Each year, millions of people in the U.S. are sickened by food-borne pathogens that thrive in undercooked or spoiled food.

Engineered van der Waals crystal mimics neuronal cells with light-driven learning

16 June 2026 at 15:00
A research team led by Professor Taesung Kim of the School of Mechanical Engineering at Sungkyunkwan University (SKKU) has developed an optoelectronic synaptic device that mimics the functions of human neurons and synapses at the device scale. The researchers designed a van der Waals (vdW) crystal through a single-step sulfurization process using mixed plasma. The device operates under optical stimuli, offering a structural solution for configuring semiconductor materials for brain-inspired computing.
