NASA scientists have created a new recipe that captures key flavors of the brownish-orange atmosphere around Saturn's largest moon, Titan.
The recipe is used for lab experiments designed to simulate Titan's chemistry. With this approach, the team was able to classify a previously unidentified material discovered by NASA's Cassini spacecraft in the moon's smoggy haze.
Friday the thirteenth proved unlucky for Nanauk as environmental conditions worsened and tore the storm apart. By 09:00 UTC (5 a.m. EDT), the Joint Typhoon Warning Center (JTWC) issued their final warning on the tropical cyclone. At that time, maximum sustained winds were near 35 knots (40 mph/65 kph) and weakening quickly. The storm's last official position was at 21.3 north latitude and 64.3 east longitude, about 285 nautical miles (328 miles/528 km) southwest of Karachi, Pakistan. At that time the dissipating storm was moving to the north at 9 knots (10 mph/~17 kph).
Hurricane Cristina intensified rapidly on June 12 and infrared satellite data showed cloud top temperatures became extremely cold as thunderstorms towered to the top of the troposphere. One day later, Cristina was weakening quickly and infrared data showed cloud top temperatures were warming as the cloud tops dropped.
Referees may soon have a new way of determining whether a football team has scored a touchdown or gotten a first down. Researchers from North Carolina State University and Carnegie Mellon University, in collaboration with Disney Research, have developed a system that can track a football in three-dimensional space using low-frequency magnetic fields.
Tropical Cyclone Nanauk is holding its own for now as it moves through the Arabian Sea. NASA's Aqua satellite took its cloud top temperatures to determine its health.
When the TRMM satellite flew over Cristina on June 11, 2014 at 1142 UTC (4:42 a.m. PDT) it was a hurricane. A rainfall analysis that used data from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) instruments was overlaid on an enhanced infrared image received by NOAA's GOES-East satellite at 1145 UTC (7:45 a.m. EDT) to provide a complete picture of the hurricane's cloud extent and rainfall rates. The TRMM TMI data clearly revealed that an eye had developed indicating that Cristina was definitely a hurricane.
Research findings presented today at the European League Against Rheumatism Annual Congress (EULAR 2014) suggest that exercise transiently suppresses local and systemic inflammation, reinforcing the beneficial effects of exercise and the need for this to be regular in order to achieve clinical efficacy in rheumatic disease.
Children of parents who use subsidies to purchase center-based care in the toddler years are more likely to be enrolled in Head Start or public prekindergarten in their preschool years, according to a new study. The research, conducted at Georgetown University and Columbia University, appears in the journal Child Development.
The first ecological study of an entire glacier has found that microbes drastically reduce surface reflectivity and have a non-negligible impact on the amount of sunlight that is reflected into space.
The research, led by the University of Leeds and published today [12 June] in the journal FEMS Microbiology Ecology, will help improve climate change models that have previously neglected the role of microbes in darkening the Earth's surface.
The world of astronomy has changed. An astronomer used to have to travel to a remote location and endure long, cold nights, patiently guiding a telescope to collect precious photons of light. Now, a proliferation of online archives allows astronomers to make discoveries from the comfort of their own offices.
Using the Atacama Large Millimeter/submillimeter Array (ALMA), a team of researchers reports the first-ever detection of molecular gas -- the fuel for star formation -- in two galaxies that were previously rocked by gamma ray bursts (GRBs), the brightest explosions in the Universe. These new observations revealed that the molecular gas was concentrated toward the centers of the galaxies, while the GRBs occurred in unusual environments that were surprisingly bereft of gas yet rich in dust.
Tropical Cyclone 02A has consolidated and strengthened over a 24 hour period between June 10 and 11 and an image from NASA's Aqua satellite showed a more rounded tropical storm, despite wind shear.
Observations from the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time directly mapped out the molecular gas and dust in the host galaxies of gamma-ray bursts (GRBs) — the biggest explosions in the Universe. In a complete surprise, less gas was observed than expected, and correspondingly much more dust, making some GRBs appear as "dark GRBs". This work will appear in the journal Nature on 12 June 2014 and is the first ALMA science result on GRBs to appear. It shows ALMA's potential to help us to better understand these objects.
Before Tropical Storm Cristina intensified into a hurricane, NASA's TRMM satellite passed overhead and gathered data that showed areas of heavy rainfall were occurring within.
Larvae of the marine bristle worm Platynereis dumerilii orient themselves using light. Early in their development, these larvae swim towards the light to use surface currents for their dispersal. Older larvae turn away from the light and swim to the sea floor where they develop into adult worms. Scientists of the Max Planck Institute for Developmental Biology in Tübingen have discovered that this change in the behavioural response to light is coupled to different neuronal systems underlying the eyes.
