Earlier this year, the National Science Foundation's Very Long Baseline Array telescope turned its gaze to NASA's famed Voyager 1 and captured an image of this iconic spacecraft's faint radio signal. The Green Bank Telescope also detected Voyager's signal, picking it out from the background radio noise in less than one second.

NASA's Hubble Space Telescope has uncovered the largest known population of globular star clusters, an estimated 160,000, swarming like bees inside the crowded core of the giant grouping of galaxies Abell 1689. By comparison, our Milky Way galaxy hosts about 150 such clusters.

University of Utah bioengineers discovered our understanding of language may depend more heavily on vision than previously thought: under the right conditions, what you see can override what you hear.
Once every 30 years or so, or roughly one Saturnian year, a monster storm rips across the northern hemisphere of the ringed planet. In 2010, the most recent and only the sixth giant storm on Saturn observed by humans began stirring. It quickly grew to superstorm proportions, reaching 15,000 kilometers (more than 9,300 miles) in width and visible to amateur astronomers on Earth as a great white spot dancing across the surface of the planet.
Scientists at Brookhaven National Laboratory used an indirect method to detect fluctuating "stripes" of charge density in a material closely related to a superconductor. The research identifies a key signature to look for in superconductors as scientists seek ways to better understand and engineer these materials for future energy-saving applications.
Ground-breaking new research from a team of evolutionary biologists at Indiana University shows for the first time how asexual lineages of a species are doomed not necessarily from a long, slow accumulation of new mutations, but rather from fast-paced gene conversion processes that simply unmask pre-existing deleterious recessive mutations.
By studying rare families in which a daughter shares the same Y chromosome as her father, Michael Weiss, MD, PhD, and his colleagues at the CWRU School of Medicine have determined that the pathway for male sexual development is not as consistent and robust as scientists have always assumed.
University of Iowa researchers say that the common fruit fly, Drosophila melanogaster, is an ideal model to study hearing loss in humans caused by loud noise. The reason: The molecular underpinnings to its hearing are roughly the same as with people.

The light-year-long knot of interstellar gas and dust, seen in this Hubble photo, resembles a caterpillar on its way to a feast. Harsh winds from extremely bright stars are blasting ultraviolet radiation at this 'wanna-be' star and sculpting the gas and dust into its long shape.
Physicists have reproduced a pattern resembling the cosmic microwave background radiation in a laboratory simulation of the Big Bang, using ultracold cesium atoms in a vacuum chamber at the University of Chicago.

University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.
Like volunteers handing out cups of energy drinks to marathon runners, specially engineered “helper cells” transplanted along with stem cells can dole out growth factors to increase the stem cells’ endurance, at least briefly, Johns Hopkins researchers report. Their study, published in the September issue of Experimental Neurology, is believed to be the first to test the helper-cell tactic, which they hope will someday help to overcome a major barrier to successful stem cell transplants.
Scientists have detected magmatic water — water that originates from deep within the Moon's interior — on the surface of the Moon. These findings, published in the August 25 issue of Nature Geoscience, represent the first such remote detection of this type of lunar water, and were arrived at using data from NASA’s Moon Mineralogy Mapper (M3).

New research from the Monell Center reveals that bubbles are not necessary to experience the unique ‘bite’ of carbonated beverages, which actually comes from carbonic acid. Bubbles do, however, enhance carbonation’s bite through the light physical feel of the bubbles picked up by our sense of touch.

While observing a newborn star, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope discovered twin jets of matter blasting out into space at record-breaking speed. These surprisingly forceful molecular "winds" could help refine our understanding of how stars impact their cloudy nurseries and shape their emerging solar systems.
On August 20, JoVE, the Journal of Visualized Experiments will publish a technique accommodating two challenges inherent in brain-implantation technology: gauging the property changes that occur during implantation and measuring them on a micro-scale.
When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by NCAR shows that three atmospheric patterns drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably.
Virginia Tech researchers integrated a specific type of sensor into a typical construction helmet to allow continuous and noninvasive monitoring of construction workers’ blood gas saturation levels. The results of their study showed that a user of this helmet would be warned of impending carbon monoxide poisoning with a probability of greater than 99 percent, and won them a Best Paper award.
