Developing synthetic materials that are as dynamic as those found in nature, with reversibly changing properties and which could be used in manufacturing, recycling and other applications, is a strong focus for scientists.
In a world-first, researchers from Queensland University of Technology (QUT), Ghent University (UGent) and Karlsruhe Institute of Technology (KIT) have pioneered a novel, dynamic, reprogrammable materialâby using green LED light and, remarkably, darkness as the switches to change the materialâs polymer structure, and using only two inexpensive chemical compounds. One of these compounds, naphthalene, is well known as an ingredient in moth repellents.
The new dynamic material could potentially be used as a 3D printing ink to print temporary, easy-to-remove support scaffolds. This would overcome one of the current limitations of the 3D process to print free-hanging structures.
Teslaâs new Roadster is going to come with an optional âSpaceX packageâ that will include cold air thrusters to improve performance.
Now CEO Elon Musk says that the thruster will be hidden behind the license plate.
When first unveiling the vehicle, Musk claimed a list of insanely impressive specs for the new Roadster, including 0â60 mph in 1.9 sec, 620-mile of range, and more.
Thereâs no doubting that graphene, a single layer of graphite with the atoms arranged in a honeycomb hexagonal pattern, is one of scienceâs most versatile new materials. Capable of doing everything from filtering the color out of whisky to creating body armor thatâs stronger than diamonds, graphene exhibits some truly unique qualities. However, while some mainstream uses of graphene have emerged, its use remains limited due to the challenge of producing it at scale. The most common way to make graphene still involves using sticky tape to strip a layer of atoms off ordinary graphite.
Thatâs something that researchers from the University of Rochester and the Netherlandsâ Delft University of Technology have been working to change. Theyâve figured out a way to mass produce graphene by mixing oxidized graphite with bacteria. Their method is cost-efficient, time-efficient, and sustainable â and may just make graphene a whole lot more available in the process.
âIn our research, we have used bacteria to produce graphene materials on a bulk scale, and we showed that our material is conductive, and both thinner and able to be stored longer than chemically produced graphene materials,â Anne Meyer, professor of biology at the University of Rochester, told Digital Trends. âThese properties demonstrate that our bacterial graphene would be well suited for a variety of applications, such as electrical ink or lightweight biosensors. Our approach is also incredibly simple and environmentally friendly compared to chemical approaches. All we have to do is mix our bacteria with the graphene precursor material, and leave them sitting on the benchtop overnight.â
They are found in many freshwater lakes.
A potentially deadly brain-eating amoeba has been detected in a Louisiana neighborhoodâs drinking water â the third time the terrifying discovery has been made in the same parish since 2015, reports said.
Naegleria fowleri, which causes fatal brain swelling and tissue destruction, was found over the weekend in Terrebonne Parish, deep in the Louisiana bayou about an hour south of New Orleans, WWL-TV reported.

If humanity is to ever settle new planets, we will need radically new technologies; this much is obvious. But we may already have the perfect material to step up and fill the role: graphene. It is easily transported, easily manipulated, and an abundance of carbon in the galaxy could bode well for graphene, which is a carbon-based material. Its strength and versatility could well become a crucial component in colonization. For instance, spacecraft filled with advanced, massive 3D printers could ferry intrepid settlers to new corners of the galaxy, supplying a near-endless supply of material and equipment, perhaps even being used to construct homes that can withstand the conditions of other worlds.
Grapheneâs discovery in 2004 sparked the flame of endless possibility within the science and technology communities due to its astounding properties. Only a single atomic layer thick and constructed in a lattice, honeycomb-like formation, graphene is nearly 200 times stronger than steel and better at conducting electricity and heat than any other conductor. Itâs flexible, allows 97 percent of white light to pass through it (making it perfect for solar energy), and the list of properties continues.
