Preparing for Pluto’s Undiscovered Satellites

Searching for the Undiscovered Satellites of Pluto

New computer simulations suggest that NASA’s New Horizons spacecraft will encounter many small satellites as it nears the binary planet Pluto-Charon in 2015. In 2015, NASA’s New Horizons spacecraft will encounter the binary planet Pluto-Charon and its coterie of small satellites. Discovered in June 2005, the satellites Nix and Hydra orbit Pluto-Charon at distances roughly […]

Lack of Sleep Leads to Eating and Weight Gain

Lack of Sleep Leads to Eating and Weight Gain

A new study from the University of Colorado Boulder suggests that a lack of sleep leads to eating and weight gain, finding that sleep-restricted people eat during their biological nighttime when internal physiology is not designed to be taking in food. Sleeping just five hours a night over a workweek and having unlimited access to […]

NASA’s Swift Discovers a Young Galactic Supernova Remnant

Swift Satellite Has Uncovered the Previously Unknown Remains of a Shattered Star

While using NASA’s Swift satellite to perform an X-ray survey of our galaxy’s central regions, a team of researchers discovered a young galactic supernova remnant, designated G306.3–0.9. NASA’s Swift satellite has uncovered the previously unknown remains of a shattered star. Designated G306.3–0.9 after the coordinates of its sky position, the new object ranks among the […]

Hubble Gazes on Ring Galaxy Zw II 28

Hubble Image of Ring Galaxy Zw II 28

Hubble takes a closer look at ring galaxy Zw II 28 in this newly released image. Galaxies can take many forms — elliptical blobs, swirling spiral arms, bulges, and disks are all known components of the wide range of galaxies we have observed using telescopes like the NASA/ESA Hubble Space Telescope. However, some of the […]

Researchers Grow Bioengineered Teeth

Researchers Grow Bioengineered Teeth

In a new study, scientists at King’s College were able to produce bioengineered teeth containing dentine, enamel and viable roots by using cells isolated from adult human gingival tissue combined with mouse embryonic tooth mesenchyme cells. New research published in the Journal of Dental Research describes an advance in efforts to develop a method to […]

14 Adult Patients in Long Term Functional Remission of HIV After Treatment

14 Adult Patients in Long Term Functional Remission of HIV

A newly published study reports on fourteen adult patients in long term functional remission of HIV seven years after being taken off early antiretroviral treatment. The work published today in PLoS Pathogens describes the control of HIV infection after early treatment of 14 patients who have been off therapy for 7.5 years (the cohort ANRS […]

C60 Detected in Planetary Nebula M1-11

Molecules of Carbon Detected in a Dying Star

Using data from several telescopes, researchers have detected C60 in the planetary nebula M1-11, bringing scientists closer to understanding the prevalence and formation of C60 in space. An international team of astronomers led by Masaaki Otsuka (Academia Sinica Institute of Astronomy and Astrophysics or ASIAA) has detected the C60 fullerene (molecules of carbon with 60 […]

Researchers Observed the Atmosphere of a Jupiter-Like Planet Beyond Our Solar System

A Detailed Examination of the Atmosphere of a Jupiter Like Planet Beyond Our Solar System

Using a high resolution imaging spectrograph, researchers have observed the atmosphere of a Jupiter like planet beyond our Solar System in unprecedented detail, uncovering the chemical fingerprints of specific molecules and revealing a cloudy atmosphere containing carbon monoxide and water vapor. A team of astronomers, including Quinn Konopacky of the Dunlap Institute for Astronomy & […]

Cassini Data Reveals Jupiter’s ‘Hot Spots’ Are Created by a Rossby Wave

Hot Spots in Jupiter Atmosphere Are Created by a Rossby Wave

Using images from NASA’s Cassini spacecraft, researchers closely tracked the shape of multiple “hot spots” over a period of time on Jupiter’s surface, finding evidence that these hot spots are created by a Rossby wave, a pattern also seen in Earth’s atmosphere and oceans. NASA postdoctoral fellow David Choi discusses his study of dark features […]

Controlling the Spin Polarization of Electrons in Three Dimensions

Scientists Discover How a Photon Beam Can Flip the Spin Polarization of Electrons

Scientists from the Berkeley Lab discovered that when topological insulators are hit with a laser beam, the spin polarization of the electrons they emit can be completely controlled in three dimensions. Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single […]

Antipurinergic Therapy Reverses the Symptoms of Autism in Mouse Model

Drug Treatment Corrects Autism Symptoms in Mouse Model

Using antipurinergic therapy, researchers were able to restore cell communications in a mouse model of autism, reversing the symptoms of the disorder. Autism results from abnormal cell communication. Testing a new theory, researchers at the University of California, San Diego School of Medicine have used a newly discovered function of an old drug to restore […]
