There’s a limited supply of donor human corneas, meaning that not everyone who needs an eyesight-saving transplant can get one. As a result, biosynthetic corneas have recently been developed. These could become quicker and easier to produce, as scientists have now successfully 3D-printed the things. read more

Weapon Wednesday – Special Operations Rapidly Deployable Field Workshops

DEPARTMENT OF DEFENSE

U.S. Special Operations Forces operate a fleet of portable, rapidly deployable field workshops that can repair, manufacture, or even improve equipment in the field. The workshops, known as Mobile Technology Repair Complexes, are powered by renewable energy and stuffed with tools including lathes, welders, and 3D printers. MTRCs have proven their worth in the war against the Islamic State in Syria, quickly building ad hoc medical facilities from available materials. read more

We Could Soon Have Unlimited Transplant Organs

Futuristic ‘smart’ tissues could grow into any organ and automatically connect to the bodies of transplant patients, study reveals

Scientists have created synthetic tissues that can rebuild themselves into any part of the body, a new study reveals.

The researchers developed a new compound that mimics DNA’s instructions for cells to turn into various tissues.

Using this method, the University of California, San Francisco team could effectively automate these cells to take on various structures and colors, a process akin to what happens in the early stages of natural embryonic development.

Exerting this level of control to create complex biological forms indicates that scientists may soon be able to stop 3D-printing organs and grow them the way nature does instead. read more

New Route to Early America Found?

How early humans first got to the Americas has long been debated by scientists.

The conventional story goes that the earliest settlers came via Siberia, crossing the now-defunct Bering land bridge on foot and trekking through Canada.

However, some scientists believe the first Americans may have taken a coastal route along Alaska’s Pacific border to enter the continent.

Now, a new study has come up with some of the first evidence to support this theory by looking at boulders and bedrock in the region. read more

Glioblastoma is one of the most deadly forms of cancer. Affecting the brain, those unlucky enough to receive a diagnosis don’t have many treatment options – and usually a median life expectancy of just over a year. Now, researchers at MIT have developed nanoparticles that could provide hope, crossing the blood-brain barrier and delivering two types of drugs to fight tumors. read more

Cassette Decks Making a Comeback

Though digital music accounts for much of what we now listen to, old school formats like vinyl and audio cassettes steadfastly refuse to disappear. The former is enjoying something of a healthy revival at the moment, but trying to find an album released on audio cassette is a little more challenging. read more

At the cellular level, aging and cancer are two sides of the same coin. The mechanism that limits a cell’s lifespan can be slowed down, but that can turn them cancerous, as they divide unchecked.

Now, scientists at EPFL have found a way to manipulate that mechanism to effectively turn off cancer’s immortality, letting it die slowly and naturally. read more

Much mystery surrounds the physiological processes by which humans age, but scientists are learning more all the time. With this knowledge come new possibilities around how we can not only slow them down, but possibly even reverse them. A new breakthrough at the University of Colorado is the latest advance in the area, demonstrating how a chemically altered nutritional supplement may well reverse aging of the blood vessels, in turn giving cardiovascular health a vital boost. read more

Australian company Titomic has unveiled what it claims is the world’s largest metal 3D printer at its fully automated Melbourne facility. Utilizing a patented process co-developed with Australian federal scientific research agency the CSIRO, the 3D metal printer boasts a build area 9 m long, 3 m wide and 1.5 m high (29.5 x 9.8 x 4.9 ft), however the printing process isn’t constrained to this booth size, meaning it could be used to print even larger objects. read more

Weapon Wednesday – PEARL Systems Locates Gunfire

Metravib

A new portable system small enough to mount on a personal firearm provides its user with the ability to quickly locate the source of hostile gunfire. The PEARL system, created by French defense contractor Metravib, uses acoustic sensors to determine the source of gunfire during the confusion of combat. read more
