'Helix-to-tube' a simple strategy to synthesize covalent organic nanotubes
more »
Organic nanotubes (ONTs) are tubular nanostructures composed of organic molecules that have unique properties and have found various applications, such as electro-conductive materials and organic photovoltaics. A group of scientists have now developed a simple and effective method for the formation of robust covalent ONTs from simple molecules. This method is expected to be useful in generating a range of nanotube-based materials with desirable properties.

The rise and fall of galaxy formation
more »
Astronomers have charted the rise and fall of galaxies over 90 percent of cosmic history. The FourStar Galaxy Evolution Survey has built a multicolored photo album of galaxies as they grow from their faint beginnings into mature and majestic giants. They did so by measuring distances and brightnesses for more than 70,000 galaxies spanning more than 12 billion years of cosmic time, revealing the breadth of galactic diversity.

Anomalous grooves on Martian moon Phobos explained by impacts
more »
Some of the mysterious grooves on the surface of Mars' moon Phobos are the result of debris ejected by impacts eventually falling back onto the surface to form linear chains of craters, according to a new study. One set of grooves on Phobos are thought to be stress fractures resulting from the tidal pull of Mars. The new study addresses another set of grooves that do not fit that explanation.

NASA team probes peculiar age-defying star
more »
For years, astronomers have puzzled over a massive star lodged deep in the Milky Way that shows conflicting signs of being extremely old and extremely young. Researchers initially classified the star as elderly, perhaps a red supergiant. But a new study by a NASA-led team of researchers suggests that the object, labeled IRAS 19312+1950, might be something quite different -- a protostar, a star still in the making.

Proxima b is in host star's habitable zone, but could it really be habitable?
more »
The world's attention is now on Proxima Centauri b, a possibly Earth-like planet orbiting the closest star, 4.22 light-years away. The planet's orbit is just right to allow liquid water on its surface, needed for life. But could it in fact be habitable? If so, the planet evolved very differently than Earth, say researchers say astronomers, geophysicists, climatologists, evolutionary biologists and others who study how distant planets might host life.
