New research suggests that replacing polyethylene (PE) packaging with paper, glass, aluminum or steel often does not reduce environmental impacts across a product's life cycle.

Autonomous triangular modules could build tomorrow's mega-observatories

Private companies are getting better at launching more mass into space with larger rockets. But there is still a major constraint on the size of objects we can get into orbit—fairing size. This places physical constraints on the overall shape of what we can launch and severely li

Researchers develop AI tool to map microRNA binding sites on circular RNAs

Circular RNAs (circRNAs) are loop-shaped molecules that can influence gene regulation through interactions with microRNAs (miRNAs). This matters because circRNAs can exist as different full-length isoforms, and their back-splice junction (BSJ) connects the two ends of the RNA. Tr

Acupuncture and mutual exchange in Chinese and Soviet science

Previous accounts of the scientific relationship between communist China and the Soviet Union have depicted it as one of subordination, with the Russians exporting knowledge to the Chinese or scavenging from their bodies of knowledge. A new article in Isis, however, posits that t
