There are precious metals in the electronic objects we use every day but recovering them from old or broken machines can involve harsh chemicals like cyanide. A new sponge made of graphene and chitosan (a shrimp shell sugar) can filter gold from e-waste. Developed at the National University of Singapore, it can recover up to 99.5% of gold.
New analysis by National Astronomical Observatory of Japan (NAOJ) suggests the 2022 image of Sagittarius A*, the Milky Way's supermassive black hole, may not fully capture its true structure. While this picture has been validated, errors during the processing may have slipped by and researchers are now proposing a more elongated shape than the one currently in the photo.
Stingless bee honey is packed with trehalulose—a rare sugar that is not found in many foods. Researchers from the University of Queensland and University Putra Malaysia found that it has a wide variety of health benefits including managing diabetes, weight loss, and even preventing cavities.
Scientists at the University of Tokyo have created hybrid cells that combine hamster cells with algae chloroplasts. By putting the chloroplasts into the cells, the team were able to create cells that can get energy from photosynthesis. This breakthrough could help faster tissue growth for transplants or lab-grown meat.
In a string of words that sound like a fantasy story, an ancient spider relative has been found encased in fool’s gold. The University of Oxford and Yunnan University have unveiled this well-preserved fossil which had long hairs to help it sense the environment. This discovery could help scientists find out when things like antennae first appeared.
