Strange quantum experiment shows “negative time” is more than an illusion
Photons passing through a cloud of atoms emerged early enough to suggest negative dwell time inside the cloud. Researchers confirmed this counterintuitive result using weak measurements of the atoms themselves, demonstrating the effect is physically real rather than an artifact of measurement technique.

A metal-free dye-fixing process makes natural plant dyes more durable on textiles without requiring metal additives. The method is described in the International Journal of Materials and Product Technology as a way to address durability challenges that have limited wider adoption of plant dyes in sustainable clothing production.
Social influence can help tackle climate change
Social influence from various groups including celebrities, athletes, healthcare workers, religious leaders, and everyday contacts like family and neighbors can accelerate climate action, according to a study by the Center for Climate Change and Social Transformations. The research identified multiple influence sources spanning from public figures to hairdressers and small business owners as capable of shifting climate-related attitudes and behaviors.
New biosynthetic pathway could expand production of high-value bio-based oils
A new biosynthetic pathway enables production of high-value bio-based oils with unusual fatty acids containing novel chain lengths or functional groups. These oils serve as feedstocks for biofuels and bioproducts because they provide energy-dense hydrocarbon molecules.
