The tighter a knot is tied, the stronger the material becomes.

By suspending tiny metal nanoparticles in liquids, Duke University scientists can use conductive ink-jet-printed conductive “inks” to print inexpensive, customizable RFID and other electronic circuit patterns on just about any surface — even on paper and plastics.

Printed electronics, which are already being used widely in devices such as the anti-theft radio frequency identification (RFID) tags you might find on the back of new DVDs, currently have one major drawback: for the circuits to work, they first have to be heated to 200° C (392°F) to melt all the nanoparticles together into a single conductive wire.

Researchers have identified a drug that can regenerate teeth from the inside out, possibly reducing the need for artificial fillings.

The drug was previously used in Alzheimer’s clinical trials, and it now appears to improve the tooth’s natural ability to heal itself. It works by activating stem cells inside the tooth’s pulp centre, prompting the damaged area to regenerate the hard dentin material that makes up the majority of a tooth.

“The simplicity of our approach makes it ideal as a clinical dental product for the natural treatment of large cavities, by providing both pulp protection and restoring dentine,” said lead author Paul Sharpe from King’s College London.

“The human energy field exists as an array of oscillating energy points that have a layered structure and a definite symmetry and these properties fulfill the definition of a normal crystal in material form” – Marc Vogel.

Stronger Graphene; can you imagine have a car or SUV that is solid like a Sherman Tank and weighs the same or less than your car or SUV does today; or a commercial jet that it’s fuselage remains intact when it crashes while protecting others inside; or a building that does not get ripped apart in a tornado? With this form of graphene it may be possible.

Now a team of researchers at MIT have developed a computer model that simulates fusing flakes of graphene into three-dimensional configurations.

According to the researchers, Graphene is a strong material. As such, the porous graphene material can be used in the construction industry by creating strong and light materials.

It’s ten times stronger than steel but is only 5% as dense, and it could revolutionize architecture on Earth, too.

And it’s inspired by X-Men’s Wolverine.

In Brief

• Researchers have created a 3D bulk material from silk fibroin that can be programmed to activate specific tasks when exposed to conditions like temperature or infrared light.
• The material could be used to create everything from hormone-emitting orthopedics to surgical pins that change color when they near their mechanical limits.

Engineers from Tufts University have just created a new, versatile material that could be optimized for a number of purposes, particularly within the medical field. The material was constructed out of special proteins called silk fibroins, and it can be programmed for specific biological, chemical, or mechanical tasks. The study was published online in Proceedings of the National Academy of Sciences (PNAS).

The team used water-based fabrication methods inspired by protein self-assembly to produce 3D bulk materials from silk fibroin. Fibroin, the structural protein that gives silk its durability, was chosen because it allowed for the easiest manipulation of the resulting substance’s form, as well as smoother modification of function. It’s also completely biodegradable.
