Synthetic muscle ready for launch

more »

NASA plans to send advanced material into space on Monday, April 13. The Synthetic Muscle™ has been developed to adhere to metal, and could be used in robotics in deep space travel such as travel to Mars because of its radiation resistance, scientists say. "Based on the good results we had on planet Earth, the next step is to see how it behaves in a space environment," said an engineer who worked on the project.

An exoplanet with an infernal atmosphere: 1000 kph winds; 3000 degree temps

more »

Astronomers have come to measure the temperature of the atmosphere of an exoplanet with unequaled precision, by crossing two approaches. The first approach is based on the HARPS spectrometer and the second consists of a new way of interpreting sodium lines. From these two additional analyses, researchers have been able to conclude that the HD189733b exoplanet is showing infernal atmospheric conditions: wind speeds of more than 1000 kilometers per hour, and the temperature being 3000 degrees. These results open up perspectives to approach the study of exoplanet atmospheres.

When you land, can you stand? One-Year Mission video miniseries: Functional performance

more »

You always want to be the last man standing, especially at NASA. Optimal functional performance, such as standing, is taken even more seriously when preparing for future missions to Mars and beyond. Learn why functional performance is important for astronauts and patients recuperating from long-term bed rest.

Inorganic nanowire follows the crystal structure of its graphene template

more »

(Phys.org)—Graphene, a two-dimensional form of carbon, has many properties making it uniquely suited for nanodevices. For one, even though it is comprised of a network of carbon atoms, it displays extraordinary conductivity through its π-electron network. Additionally, graphene is an inexpensive, flexible substrate, making it a practical option for device construction. Many groups are interested in ways to align nanomaterials on graphene surfaces rather than functionalizing graphene, which changes some of graphene's desirable properties.

Graphene looking promising for future spintronic devices

more »

Researchers have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim to manufacturing faster and more energy-efficient memory and processors in computers.

Cosmic debris: Study looks inside the universe’s most powerful explosions

more »

A new study provides an inside look at the most powerful explosions in the universe: gamma-ray bursts. These rare explosions happen when extremely massive stars go supernova. The stars' strong magnetic fields channel most of the explosion's energy into two powerful plasma jets, one at each magnetic pole. The jets spray energetic particles for light-years in both directions, at close to light speed.

Spontaneous formation of biomimetic, nanoporous membrane channels

more »

For the first time, spontaneous insertion of carbon nanotubes (CNTs) into natural as well as synthetic cell membranes to form pores that mimic biological channels has been demonstrated. Despite their extremely simple structure, these CNT-membrane pores replicate the major functional behaviors of porins (protein-based biological channels), such as selective transport of protons, water, ions, and small molecules.

Small solar eruptions can have profound effects on unprotected planets

more »

While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable -- a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions.
