16+ hour, 54+ min ago A team of scientists has engineered bacteria that converts chemicals made from plastic bottles into a common drugstore painkiller called paracetamol, which is the active ingredient in Tylenol. Inside small flasks in a Scottish lab, the microbes converted plastic-based starting…...

5+ day, 11+ hour ago Water looks familiar in a glass, yet it behaves very differently when pushed to extremes. When researchers in Manchester squeezed water into ultra-thin channels inside crystals, it carried electric current up to 100,000 times better than ordinary water. This discovery is…...

6+ day, 9+ hour ago Indoor rooms often contain far more chemicals than most people realize. Air moves slowly inside enclosed spaces, so chemicals released from everyday products linger instead of drifting away. Dust settles on furniture, sticky films form on toys, and fumes rise…...

1+ week, 15+ hour ago A new thermoelectric device boosts the electricity generation capability of a little-known solar technology by 15 times. Instead of relying on conventional solar cells, it pulls electricity straight from heat created by concentrated sunlight. The prototype belongs to a class of…...

1+ week, 17+ hour ago Engineers in Australia have built a sodium battery that keeps working for more than 5,000 hours in lab tests.It uses a solid, plastic-like core instead of flammable liquid, which makes the whole system much harder to overheat. The prototype, developed…...

1+ week, 1+ day ago Researchers in Finland have shown that simple molecules related to everyday oils, plus visible light, can dissolve silver without relying on harsh chemicals." The same chemistry can pull silver from waste and then return it as solid metal ready for…...

1+ week, 1+ day ago Oxygen began entering Earth's oceans around 2.32 billion years ago, and shallow seas followed within a few million years. Scientists at the Woods Hole Oceanographic Institution (WHOI) traced that change in ancient rocks from South Africa. Chemical signatures in the rocks…...

1+ week, 4+ day ago At a steaming creek in California's Lassen Volcanic National Park, a tiny amoeba just raised the heat ceiling for complex cells." A Syracuse University team reports that the single-celled eukaryote divided at about 145 degrees Fahrenheit. For decades, the accepted upper…...

1+ week, 4+ day ago Per-and polyfluoroalkyl substances (PFAS), long lasting human-made chemicals built from carbon and fluorine, are now used in thousands of everyday products." Scientists worry because many of these compounds stay in water, soil, and human blood for years. A group of…...

1+ week, 5+ day ago For the first time, scientists have directly seen atomic oxygen, which are single oxygen atoms not bound into molecules, moving through liquid water. These atoms stick around for tens of microseconds, a few millionths of a second, which is far…...
