It’s amazing how quickly additive manufacturing technology has been progressing. Laser sintering of metals within the manufacturing industry was a process used by only a few companies, mostly in a research capacity, just a few years ago. Now numerous companies are using laser sintering additive manufacturing machines to print extremely important metal components for a variety of products, from airliners to race cars.

New spongelike material converts solar energy into steam

July 24, 2014

The DLS that consists of a carbon foam supporting an exfoliated graphite layer.

MIT has developed a new material structure that generates steam by soaking up the sun. The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.

Researchers develop new process that raises prospects of 3D printed bone grafts

July 23, 2014

3D printing could help mend broken bones.

One of the 3D printing health applications of 3D printing discussed the most is the manufacturing of bespoke scaffolds that could be used to mend broken bones. It’s promising, but it has been held back by the difficulties in printing materials that are strong, flexible and can encourage the regrowth of healthy bone in the same way as current methods, such as bone grafts.

Generating electricity from jumping water droplets

July 21, 2014

This process can generate small amounts of electricity.

Last year, MIT researchers discovered that when water droplets spontaneously jump away from superhydrophobic (water-repelling) surfaces during condensation, the droplets can gain electric charge in the process.

You can learn a foreign language in your sleep: Study

July 18, 2014

Swiss study finds memory for new words reinforced by listening again during sleep.

Most tricks for enhancing learning that seem too good to be true usually are. Learning a new language while you sleep has exactly this kind of ring to it. How can anything you listen to while you are asleep possibly have much effect on learning?

New material discovered that makes objects invisible to touch

June 30, 2014

You can see how it “absorbs” a metal cylinder.

A new nano-material recently invented does the seemingly impossible: It hides things from touch. Just a thin layer of this amazing polymer will hide anything under it from being perceived by your sense of touch.

Why kids (and adults) should play outside

June 21, 2014

Kids who play outdoors have a stronger spiritual connection to the Earth.

A new study, published in the Journal of the Study of Religion, Nature and Culture found that children who play outdoors have a stronger sense of purpose and self-fulfilment than those who don’t.

Researchers discover 3D material that behaves like graphene

June 9, 2014

This illustration depicts fast-moving, massless electrons inside cadmium arsenide.

Researchers from Oxford, SLAC, and Berkeley Lab have found that cadmium arsenide could yield practical devices with the same extraordinary electronic properties as 2D graphene. The researchers also found that the new “semimetal” material exists in a sturdy 3D form that should be much easier to shape into electronic devices such as very fast transistors, sensors and transparent electrodes.
