Prusa Research illustration for version 1.1 of the Open Community License

Prusa opens its designs, but not the market

OCL v1.1 lets non-commercial users modify and share, but blocks commercial replication by default. Its new plugins only add more conditions. Under OSHWA’s definition, this is not open-source hardware.

James Tour and members of his Rice University team behind the ultrafast MXene synthesis method

Making a MXene in 30 Seconds Does Not Take 30 Seconds

Rice etched nine MAX families into MXenes in under 30 seconds. The raw data tell the more useful story: the reaction becomes almost instantaneous, while the full process keeps a second clock.

Tungsten carbide cutting inserts

3D printing tungsten carbide: soften it, don't melt it

Hiroshima researchers deposited tungsten carbide-cobalt with a laser and hot wire, without fully melting it: over 1400 HV with no defects, and expensive material placed only where it matters.

Narwhal tusks emerging from the water

How the narwhal builds the only straight tusk in nature

The narwhal's tusk grows in a spiral yet stays straight for over two meters. A new study reveals the mechanism: a molecular double helix with opposite chiralities that compensates for uneven deposition.
