Sculpted from a granite rock face in Sri Lanka’s North Central Province, the Avukana Buddha is an early example of colossal Buddha imagery in Sri Lanka. Its form and detailing suggest connections with sculptural traditions from Amaravati and the Gupta period, while its execution reflects regional adaptation. Discover how the sculpture and its associated finds have been linked to the doctrine of Lokottara or transcendence, later adopted by Mahayana Buddhism.

Photocatalytic systems use sunlight to split water into hydrogen and oxygen. Such an environmentally friendly approach to hydrogen production has long been touted by scientists. However, these systems often require multiple cocatalysts to drive the reactions necessary to split water, thereby throttling efficiency. However, a research group has recently unveiled a new all-in-one photocatalytic cocatalyst.

Magnesium hydride stores lots of hydrogen but the problem comes with the high temperatures needed to release it. Now, researchers have found a new catalyst that helps solve this common bottleneck, focusing on a phenomenon called the burst effect.

Biodegradable plastics are great. They provide the ductility of plastics whilst reducing the materials environmental downsides. However, in the quest for greater degradability, improving durability has received scant attention. A research group recently rectified this with the development of a new bamboo composite that emphasised both biodegradability and strength. The group also developed a means to predict how the material breaks down in water.

For 70 years, we have assumed that “attempt time” in nanomagnets is one nanosecond. For the first time ever, this value was measured experimentally by researchers at Tohoku University. Spoiler alert: it’s more than one nanosecond!
