This Isn’t Your Grandparents’ Machine Lubricant

by Michael Keller

Gears, actuators and whirring machine parts are all around us. The modern automobile alone can have upwards of 50 electric motors—from electric windshield wipers to alternators—whose guts include pieces of metal rubbing against other parts.

The only thing that keeps these components from grinding away into powder is a liquid lubricant, a substance typically made of a petroleum-derived base oil mixed with additives that reduce friction between moving parts. 

Now researchers in Germany say they have made a breakthrough in developing the next generation of lubricants. Their new liquid formulation, they say, lets small gears run with virtually no friction. The source of this wear-reducing elixir? The liquid crystals inside your computer and TV screen.

MIT’s New Robot Glove can Give You Extra Fingers
Have you ever wondered if five fingers is really enough? The folks at MIT have. Researchers in the institute’s department of mechanical engineering have created a robotic glove that adds two additional digits to the standard human claw, positioning two long fingers on either side of the hand. It’s ridiculously easy to use, too. “You do not need to command the robot, but simply move your fingers naturally.” Ford Professor of Engineering Harry Asada says. “Then the robotic fingers react and assist your fingers.” The glove’s movements are based on biomechanical synergy, the idea that each finger reacts to the movements of its peers - if you try to grasp a bottle, the glove’s extra fingers will try to help.

Scientists Create a New Type of Ultra-High-Res Flexible Display
-
We are surrounded by imperfect screens. Our smartphones, laptops, televisions, watches, billboards, thermostats and even glasses all have screens with drawbacks: Some don’t work in sunlight, others mercilessly drain your battery; some can’t do rich color, and some can’t display a true black; most can’t be rolled up and tucked in your pocket. But something better may be on the way. In research published today in Nature, scientists describe what may be the first steps toward creating a new type of ultrathin, superfast, low-power, high-resolution, flexible color screen. If the inevitable engineering difficulties in bringing a product from the lab to the living room can be overcome, these displays could combine some of the best features of current display technologies. The new displays work with familiar materials, including the metal alloy already used to store data on some CDs and DVDs. The key property of these materials is that they can exist in two states. Zap them with heat, light, or electricity and they switch from one state to the other. Scientists call them phase-change materials (PCMs). “It is really fascinating that phase-change materials, now widely used in optical and nonvolatile electronic memory devices, found a potentially new application in display technology,” said Alex Kolobov, a researcher at Japan’s Nanoelectronics Research Institute who was not involved in the new work.

Mars One Wants to Send Your Experiments to the Red Planet

The nonprofit organization that has raised eyebrows with its plans to send people on a one-way mission to Mars is now accepting proposals for scientific payloads that could fly aboard an unmanned mission to the Red Planet in 2018.

The Netherlands-based Mars One foundation aims to send a total of seven payloads: four demonstration payloads, one payload selected in a worldwide university competition and two payloads for sale to the highest bidder.

The unmanned 2018 mission will serve as preparation for a planned human mission to Mars in 2024, Mars One organizers said. As of May, the nonprofit had whittled down its pool of potential astronauts to 705 candidates. Mars One aims to send four people on a one-way trip to the Red Planet every two years, starting in 2024.

Mars One is asking for input from the scientific community in order to source the best ideas from around the world, Arno Wielders, co-founder and chief technical officer of Mars One, said in a statement.

"The ideas that are adopted will not only be used on the lander in 2018, but will quite possibly provide the foundation for the first human colony on Mars," Wielders said.

Mars One is expected to send these payloads aboard the lander that is scheduled to launch in August 2018 and will be built on the same platform used for NASA’s 2007 Phoenix mission. Mars One and Lockheed Martin are partnering to develop a mission concept for the lander.

The four demonstration payloads will test technologies needed for the permanent human settlement of Mars. These will include an experiment to collect Martian soil for water production, an experiment to extract water from the soil, a thin-film solar panel for energy generation and a camera system that will interface with a Mars-synchronous communications satellite that will relay live video to Earth, according to Mars One.

Private Team Prepares to Fire 36-Year-Old NASA Probe’s Engine


  A 36-year-old spacecraft controlled by a private team nearly performed an engine firing Wednesday (June 25) to increase its spin, but the maneuver was called off due to concerns that the probe did not receive all commands.
  
  NASA’s International Sun-Earth Explorer 3 probe, controlled by a group that calls itself the “ISEE-3 Reboot Project,” is expected to be redirected to a more advantageous orbit for Earth communications next week. But first, the team needs to increase the spacecraft’s roll very slightly.
  
  An earlier attempt to increase the roll rate was called off last Friday (June 20) after the team could not confirm the spacecraft received some test commands from Earth. This time around, the group inched closer to making the roll, but decided to stop when the very last command did not get confirmed.

Milky Way Meets Desert Sky by Babak Tafreshi

As seen on the National Geographic News our Milky Way galaxy gleams in all its splendor, as seen from La Silla observatory in the southern outskirts of the Atacama Desert, Chile.

The clear, high altitude dry desert air provides a perfect home for the La Silla, operated by the European Southern Observatory (ESO), where the 3.6-meter New Technology Telescope (NTT) makes its nightly rounds of the sky’s far reaches.

The telescope rests between the open doors in the photo. The Milky Way spans more than 100,000 light-years across, putting Earth in the cosmic suburbs, some 27,000 light-years away from the brightly glowing center of the galaxy, seen at the center of this image.

Visible to the left of the Milky Way is the bright orange star Antares at the heart of Scorpius (The Scorpion). Saturn can be seen as the brightest point to the upper left of Antares and Alpha and Beta Centauri glow in the upper right of the image. The Southern Cross (Crux) and the Coalsack dark nebula are also visible at the upper right corner.

A hovercraft that rides like a motorcycle


With what looks like a Speeder Bike from Star Wars, UCLA alum and aerospace engineer Mark DeRoche has developed a new type of hovercraft known as The Aero-X.  When onboard the rider feels like they’re driving a motorcycle.

The idea was to build a vehicle that could quickly glide over rough terrain. Your cruising speed could top out at 45mph at 10 feet off the ground on this thing.  DeRoche says it could be used by farmers, security personnel or search and rescue missions, but admits that it could also be for those who want to joyride out in the desert.

An unmanned version is also in the works for agricultural uses such as crop dusting large areas of land.

These Students Want to Send a Time Capsule to Mars

A student-led project aims to send a time capsule to Mars for future explorers to discover, its organizers announced today (June 23).

Time Capsule to Mars (TC2M), a project of the nonprofit organization Explore Mars, plans to land three small satellites, known as CubeSats, on the surface of the Red Planet within the next five years. The satellites will contain images, videos and other forms of expression from people around the globe, according to the project’s organizers.

If successful, the $25-million mission would be the first privately funded mission to Mars, the first student-led mission to another planet, the first trial of a new propulsion system and the first interplanetary CubeSat, the team said here today in a press briefing.

"We’ve got a lot of firsts, and it’s very exciting," said Emily Briere, a senior at Duke University in Durham, North Carolina, and the mission’s founder and director.

Briere told reporters that "millions of people from around the world [will be able to] send in their photo, their picture of their dog, their handwritten poem, and feel that they themselves are going to Mars and making an impact."

High voltage art by Phillip Stearns

Stearns on his project:

I’m unable to find the source of the sentiment that the camera is an extension of the eye, but it’s that very idea which I’ve intentionally taken literally, to an extreme. When looking through the datasheets on various instant color film, I was struck by the similarities between the layering of materials in the film and the layering of cells in the retinal. Though I’m not well versed in the history of film development as parallels the development in the understanding of the physiology of the retinal, the similarities were striking…

Without a camera, images were produced through a combination of processes which parallel techniques utilized in previous experiments with low-resolution digital cameras. Various household chemicals are applied to the surface of the film both before and after exposure. Through symbolic act of cleansing, the fidelity of the film is compromised. The film is also subjected to 15,000 volts of alternating current. In a flash, arcs spread out across the surface, sometimes burning holes, even igniting the film. As in our eyes, images are conveyed in a stream of such electric impulses, only here amplified some 300,000 times. I find it curious and exhilarating that the impressions left behind after developing these extreme exposures so perfectly resemble networks of blood vessels in the retina.
