When it comes to creating surfaces, it's a simple task to either make ones that are smooth or ones that are bumpy. But now researchers at MIT have created one that can be both. The 3D-printed surface they have created can be either smooth, bumpy, ridged, or channeled and can dynamically change texture through the application of pressure.

NASA astronaut Terry Virts, aboard the International Space Station (ISS), and ESA telerobotics specialist André Schiele, in the Netherlands, made space history this week with the first telerobotic "handshake" between space and Earth. Using special force feedback joysticks that acquire force data and create the sensation of pressure, Virts and Schiele brought the agencies closer to allowing astronauts in remote locations to naturally and safely control robotic devices and perform potentially dangerous or otherwise impossible tasks.

Currently, recipients of arm or leg transplants need to take immunosuppressive drugs for the rest of their lives, in order to keep the donated parts from being rejected. If we could grow our own replacement limbs, however, that wouldn't be necessary. And while we do already possess the progenitor cells needed to grow such parts, what's been lacking is a method of assembling them into the form of the desired limb. Now, however, scientists have created a shortcut of sorts – they've stripped the cells from one rat's forelimb and replaced them with live cells from another rat, creating a functioning limb that the second rat's immune system won't reject.

Wood pulp-derived nanocellulose is turning out to be pretty useful stuff. Previously, we'd heard how it could be used in things like high-strength lightweight composites, oil-absorbing sponges and biodegradable computer chips. Now, researchers from Sweden and the US have used the material to build soft-bodied batteries that are more shock- and stress-resistant than their traditional hard counterparts.

Much of our furniture is made from timber. The wood to make that furniture has to be harvested from a felled tree which is then milled, sawed, planed, sanded, put back together with glue and screws, and finished. Wouldn't it be easier to avoid most of these steps and simply coax a tree to grow into a piece of furniture? Gavin Munro wondered this too, and about a decade ago set about achieving this goal. He now creates furniture by cajoling trees to grow into one-piece items that are not only inherently practical, they are also eminently beautiful.

Researchers working at the Massachusetts Institute of Technology (MIT) claim to have created a method to better observe fermions – the sub-atomic building blocks of matter – by constructing a microscope capable of viewing them in groups of a thousand at a time. A laser technique is used to herd the fermions into a viewing area and then freeze them in place so all of the captured particles can be imaged simultaneously.

Despite always generating plenty of interest, getting a personal flight vehicle off the ground can be a huge undertaking. But a Hungarian team is looking onwards and upwards after having achieved the first manned flight of its Flike tricopter concept demonstrator.

It sounds like an old Goon Show joke, but soldiers may one day protect themselves from blasts by wallpapering temporary shelters. It may not be very decorative, but the new ballistic wallpaper under development by the US Army Corps of Engineers uses a special fiber inlay to help prevent walls from collapsing under blast effects.

Just weeks after producing its first batch of synthetic diesel fuel made from carbon dioxide and water, Audi has laid claim to another synthetic, clean-burning and petroleum-free fuel called "e-benzin." The fuel was created by Audi's project partner Global Bioenergies, in France.

All living organisms – human, animal, or otherwise – continuously move molecules around their cells. It's a crucial mechanism of life, vital for feeding cells the proteins they need to function. And now scientists at Northwestern University have created a machine that mimics this pumping mechanism. Their molecular pump is the world's first such machine developed entirely through chemical engineering in the laboratory, and it could one day power artificial muscles and other molecular machines.

Magnets are at the heart of much of our technology, and their properties are exploited in a myriad ways across a vast range of devices, from simple relays to enormously complex particle accelerators. A new class of magnets discovered by scientists at the University of Maryland (UMD) may lead to other types of magnets that expand in different ways, with multiple, cellular magnetic fields, and possibly give rise to a host of new devices. The team also believes that these new magnets could replace expensive, rare-earth magnets with ones made of abundant metal alloys.

Today there seems to be a craze for all sorts of objects jammed into bottles of spirit – scorpions, worms, and other creepy crawlies being particularly common. Actually distilling the essence of an insect to make an alcoholic beverage rather than just pickling it in a bottle, however, is a different prospect altogether. But now a company in the UK has done just that, by using an extract from ants to create a special type of gin.

Silicon photonics is an emerging technology that incorporates electronic circuits using photons of laser light rather than electrons to transmit, receive, and manipulate information. As such, a silicon photonic CPU could potentially process information at the speed of light – millions of times faster than computers available today. In a step towards this goal, engineers working at the University of Utah have developed an ultra-compact photonic beam-splitter so small that millions of these devices could fit on a single silicon chip.

A study of skin wound healing in 40 (human) volunteers has found that electrical stimulation significantly speeds up the healing process. The researchers hope to now develop and test dressings and devices that could be used in treatment of human or veterinary surgical wounds, sports injuries, and other serious skin trauma.

It's one thing to 3D-print something as advanced as a jet engine, but it's another to fuel it up and push the start button. That's the step that GE Aviation took when it recently fired up a simple jet engine made entirely of 3D-printed parts in a test stand normally reserved for commercial jet power plants.
