Mines, drones, supplies: Australia lets adversaries know what Ghost Shark can do
Australia’s disclosure last week of capabilities of the Ghost Shark uncrewed submarine sent a warning to potential adversaries about the country’s wartime options. The announcement also exhibited technological progress to AUKUS partners and let allies know of purchase and partnership opportunities.
Storytelling in Intelligence: Theoretical Foundations
Abstract Intelligence analysts frequently generate and assess “stories” to describe and explain what is going on in some situation. This activity has had little theoretical attention. The term narrative abduction is used for the processes by which reasoners estimate the plausibility of explanatory stories. This article provides a theoretical framework with analyses of key concepts, including narratives, narrative truth, narrative plausibility, and explanation.

Programmable materials: Hydrogels capable of complex movement created
Living organisms expand and contract soft tissues to achieve complex, 3-D movements and functions, but replicating those movements with human-made materials has proven challenging. A University of Texas at Arlington researcher recently published groundbreaking research in Nature Communications that shows promise in finding a solution.
First 3D-printed human corneas
The first human corneas have been 3D printed by scientists at Newcastle University, UK. It means the technique could be used in the future to ensure an unlimited supply of corneas. As the outermost layer of the human eye, the cornea has an important role in focusing vision. Yet there is a significant shortage of corneas available to transplant, with 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder.
From Newton to Hawking and beyond: a short history of the Lucasian Chair
On July 1 physicist Michael Cates will be the 19th person to sit in what is perhaps the most prestigious “chair” in science when he assumes the post of the Lucasian Professor of Mathematics at Cambridge University. Although sometimes called “Newton’s chair” after its most famous holder, Sir Isaac was not the only brilliant mind, nor the most colourful individual, to occupy the post.
Want to build a Moon base? Easy, just print it
Multi-dome lunar base being constructed, based on the 3D printing concept. Once assembled, the inflated domes are covered with a layer of 3D-printed lunar regolith by robots to help protect the occupants against space radiation and micrometeoroids.

The plug and play city: how shipping containers are changing infrastructure
We often take for granted our access to vast quantities of inexpensive goods manufactured overseas. And we often overlook the unassuming innovation that has made this global industrial revolution possible: the shipping container. While the shipping container was conceived in the 1950s by American businessman Malcom McLean, it was only widely adopted after the US military used containers to supply its war effort in Vietnam in the 1960s.
Want to build a moon base? Easy. Just print it
Planetary Resources, a company hoping to make asteroid mining into a trillion dollar industry, earlier this year unveiled the world’s first 3D printed object made from bits of an asteroid. 3D printing, and additive manufacturing processes more generally, have made many advances in recent years. Just a few years ago, most 3D printing was only used for building prototypes, which would then go on to be manufactured via conventional processes.

All of Humanity Should Share in the Space Mining Boom
One solitary asteroid might be worth trillions of dollars in platinum and other metals. Exploiting these resources could lead to a global boom in wealth, which could raise living standards worldwide and potentially benefit all of humanity. There are already companies, such as Planetary Resources, hoping to make mining in space a reality.

why we're going back to Europa
Last month NASA gave the “all systems go” for a new mission to Europa. But why go back? After all, we’re still sifting through the data from the Galileo probes fly-bys from more than a decade ago. The short answer: it’s all about life. The Jovian moons – named after Jupiter’s lovers by Simon Marius – have been a source of scientific speculation since Galileo trained his telescope on Jupiter in 1610, announcing his discovery in the Sidereal Messenger.
Out of Your Noggin? Festive Spices and Their Intoxicating History
Traditional Christmas and winter food and drinks such as mulled wine, eggnog, ginger bread and fruitcakes often call for more than a dash of what Jamie Oliver calls “festive spices” – cloves, cinnamon and nutmeg. These spices may give us more than just a taste of Christmas: they may be helping to bring on the Christmas cheer with subtle intoxicating effects. Could it be that these aromatic spices – especially nutmeg – are actually getting us high?
Move Over Big Power - the Micropower Revolution Is Here
There is no shortage of shouting and dire warnings about the state of the climate and our need to phase out fossil fuels. But there is a more silent revolution happening too — in micropower. Small-scale electricity generation is slowly replacing big fossil-fuel driven power plants, which are currently the world’s single largest contributor to greenhouse gas emissions.
