When a crystal structure of bismuth (right) is decompressed from 32,000 atmospheres (3.2 GPa) to 12,000 atmospheres (1.2 GPa) it melts into a liquid at about 23,000 atmospheres (2.3 GPa) (middle). It then recrystallizes at 12,000 atmospheres (left). The so-called metastable liquid produced by this decompression occurs in a pressure-temperature range similar to where the supercooled bismuth is produced. Supercooled liquids are cooled below the freezing point without turning into a solid or a crystal. Credit: Chuanlong Lin and Guoyin Shen, Carnegie Institution

Phase transitions surround us – for instance, liquid water changes to ice when frozen and to steam when boiled...

Tissue implants customized to a patient could soon be printed using a new type of 3D-printer under development by Nanyang Technological University, Singapore (NTU Singapore) and a Singapore-based 3D printing start-up focused on healthcare. This new printer can print the supporting structure layer by layer and insert living cells to form a live tissue that could aid in regeneration of particular tissues or organs. The industry research tie-up is one of the many partnerships made possible by the National Additive Manufacturing Innovation Cluster, also known as NAMIC.

Since the formation of NAMIC by the National Research Foundation (NRF) Singapore and SPRING Singap...

“Say hello to your personal courier. I’m here to deliver anything you need. Just tell me what, when and where and I’ll do the rest.” “Your tireless delivery bot will always be on hand to lighten your load.” Wait, when did life become so comfortable? Wasn’t there luxury convenience in something called UPS? And what about wonderful Amazon? Well, some people are excited about a robot revolution in the wings, in a new era of instant, unscheduled delivery (think small orders and think local).

A new high-tech medical device to make brain surgery safer has been developed by researchers at the University of Adelaide. The tiny imaging probe, encased within a brain biopsy needle, lets surgeons ‘see’ at-risk blood vessels as they insert the needle, allowing them to avoid causing bleeds that can potentially be fatal. The project is a collaboration with the University of Western Australia and Sir Charles Gairdner Hospital. “We call it a smart needle...
