Once upon a time, dugongs swam without disturbance throughout the seas of southern China. However, a report published this week in the journal Royal Society Open Science claims that hunting, habitat loss, collisions with ships, and other human interventions have rendered these once-abundant marine animals “functionally extinct” in China. Dugongs (Dugong dugon) are huge mammals that spend most of their time feeding on underwater seagrass, where they can weigh up

A group of US chemists converted scientific charts and graphics into tactile materials. This could aid low-vision students and scientists. The team lead by Baylor University biochemist Bryan Shaw used 3D printing to turn scientific images into thin 3D constructs called lithophanes. Shaw’s endeavour began as a personal outreach effort. My baby was born with eye tumours, so I became a doctor. Despite losing an eye and having tumours in

In the early morning hours of Thursday, an asteroid that is larger than two football fields will fly by the planet Earth (Aug. 4). At precisely 12:23 in the morning, the asteroid will go by (ET). Only a few days ago, on July 26, astronomers from NASA identified the asteroid that is now known as 2022 OE2. The meaty space rock is predicted to measure between 170 and 380 metres

Since the first successful preparation of graphene by mechanical exfoliation from graphite crystals in 2004, 2D materials have attracted dramatic attention due to their extraordinary physical properties (ultralow weight, high Young’s modulus, and high strength) and electrical properties compared with conventional bulk materials. Graphene, with a Young’s modulus of 1 TPa, is the most researched 2D material. Studies suggest that graphene in polymer matrices can boost composites’ mechanical characteristics. Graphene’s
