Tilted Terminator – Cassini Spacecraft Views Enceladus

Tilted Terminator Cassini Views Enceladus

This new image from NASA’s Cassini spacecraft shows wrinkled plains that are remarkably youthful in appearance on Saturn’s moon Enceladus. When viewed with north pointing up, as in this image, the day-night boundary line (or terminator) cuts diagonally across Enceladus, with Saturn approaching its northern summer solstice. The lit portion on all of Saturn’s large, […]

Three Datasets Produce a Unique New View of MACS J0717

Hubble Image of The Week MACS-J0717

Using the Hubble Space Telescope, the NASA Chandra X-ray Observatory and the NRAO Jansky Very Large Array, astronomers have created a unique view of MACS J0717.5+3745. In October of 2013 Hubble kicked off the Frontier Fields program, a three-year series of observations aiming to produce the deepest ever views of the Universe. The project’s targets […]

Astronomers Combine Telescope Data to Further Research on Galaxy Clusters

New Research Pushes Frontier on Galaxy Clusters

Astronomers are using data from NASA’s Chandra X-ray Observatory, the Hubble Space Telescope, and the NSF’s Jansky Very Large Array to learn more about galaxy clusters, including how they grow via collisions. Galaxy clusters are enormous collections of hundreds or even thousands of galaxies and vast reservoirs of hot gas embedded in massive clouds of […]

Methane Surface on Pluto May be Sublimating Away Into the Atmosphere

New Horizons Shows Sublimation Eating Away at Pluto’s Surface

New Horizons provides scientists with a closer look at eh surface of Pluto. Far in the western hemisphere, scientists on NASA’s New Horizons mission have discovered what looks like a giant “bite mark” on Pluto’s surface. They suspect it may be caused by a process known as sublimation — the transition of a substance from […]

Yale Researchers Track How the Brain Routes Visual Signals

Yale Scientists Track How Brain Routes Visual Signals

Newly published research from Yale’s Department of Neuroscience provides some clues to how cells in the visual cortex direct sensory information to different targets throughout the brain. Understanding how the brain manages to process the deluge of information about the outside world has been a daunting challenge. By imaging activity in the mouse brain, the […]

New Bioprinting Technique Shows Potential for Tissue Repair and Regenerative Medicine

Creating 3-D Tissue

New research details how scientists are moving closer to embedding vascular networks into thick human tissues, which could result in tissue repair and regeneration — and ultimately even replacement of whole organs. A team at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard John A. Paulson School for Engineering and […]

Scientists Reveal Amino Acids Supply Most Building Blocks for Tumor Cells

Amino Acids Supply Most Building Blocks for Tumor Cells

New research shows that amino acids, not glucose, account for the majority of cell mass in proliferating mammalian cells. Cancer cells are notorious for their ability to divide uncontrollably and generate hordes of new tumor cells. Most of the fuel consumed by these rapidly proliferating cells is glucose, a type of sugar. Scientists had believed […]

Yale Study Shows Gut Bacteria Aggressively Protect Their Territory

Study Shows Friendly Bacteria Aggressively Protect Their Territory

A newly published study from Yale University details how human gut bacteria take on many tasks crucial to health. Bacterially speaking, it gets very crowded in the human gut, with trillions of cells jostling for a position to carry out a host of specialized and often crucial tasks. A new Yale study, published the week […]

Dying Star Kohoutek 4-55 Offers a Glimpse of Our Sun’s Future

Kohoutek 4-55 Offers a Glimpse of Our Sun’s Future

This Hubble image reveals the final act of celestial beauty before the long fade into cosmic history. Invisibly buried in the center of this colorful swirl of gas is a dying star, roughly the same mass as the Sun. As a star ages, the nuclear reactions that keep it shining begin to falter. This uncertain […]

The Saturnian Sisters – Cassini Views Tethys and Rhea

Cassini Views Tethys and Rhea

This newly released image from the Cassini Spacecraft shows Saturn’s moons Tethys and Rhea. Similar in many ways, Saturn’s moons Tethys and Rhea (left and right, respectively) even share a discoverer: Giovanni Cassini, namesake of the NASA spacecraft that captured this view. The moons are named for sisters — two Titans of Greek mythology. Although […]

Neuroscientists Discover a Behavioral State Gene That May be Linked to Autism

Gene for Behavioral State May be Linked to Autism

In a newly published study, neuroscientists from MIT reeval a gene that plays a critical role in controlling the switch between alternative behavioral states – which for humans include hunger and fullness, or sleep and wakefulness. This gene, which the researchers dubbed vps-50, helps to regulate neuropeptides — tiny proteins that carry messages between neurons […]
