On the nano assembly line, tiny biological tubes called microtubules serve as transporters for the assembly of several molecular objects.

A new research platform uses a laser to measure the "nanomechanical" properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries. Clockwise from upper left, graphics of the instrument setup, and at bottom right a scanning electron microscope image of the tiny silicon cantilever used in the research.

Cortex regions that showed increased connectivity with a part of the brain’s memory hub (left), or hippocampus (red arrow), following magnetic stimulation at sites over the left parietal cortex (blue arrow). Researchers linked improved performance on an associative memory task to the boost in connectivity.

Astronomers have uncovered for the first time the earliest stages of a massive galaxy forming in the young Universe. The discovery was made possible through combining observations from the NASA/ESA Hubble Space Telescope, NASA's Spitzer Space Telescope, ESA's Herschel Space Observatory, and the W.M. Keck Observatory in Hawaii. The growing galaxy core is blazing with the light of millions of newborn stars that are forming at a ferocious rate.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), and many other telescopes on the ground and in space, an international team of astronomers has obtained the best view yet of a collision that took place between two galaxies when the Universe was only half its current age. They enlisted the help of a galaxy-sized magnifying glass to reveal otherwise invisible detail. These new studies of the galaxy H-ATLAS J142935.3-002836 have shown that this complex and distant object looks like the well-known local galaxy collision, the Antennae Galaxies.
