(Press-News.org) Tropical Storm Arthur appears to be ramping up, and NASA's Tropical Rainfall Measuring Mission or TRMM satellite spotted heavy rainfall occurring around the storm's center on July 1 when it was centered over the Bahamas.
Those heavy rains are expected to affect the southern U.S. coastline over the next several days as the National Hurricane Center expects Arthur to strengthen into a hurricane. On July 2, the NHC issued a Hurricane Watch for Bogue Inlet to Oregon Inlet, North Carolina and Pamlico Sound. In addition, a Tropical Storm Watch is in effect for the east coast of Florida from Sebastian Inlet to Flagler Beach, South Santee River South Carolina to south of Bogue Inlet, North Carolina, north of Oregon Inlet, North Carolina to the North Carolina/Virginia Border, and the Eastern Albemarle Sound.
The TRMM satellite had a good daylight look at tropical storm Arthur on July 1, 2014 at 1620 UTC (12:20 p.m. EDT) less than two hours after it was upgraded from a tropical depression. At NASA's Goddard Space Flight Center in Greenbelt, Maryland rainfall from TRMM's Microwave Imager (TMI) and Precipitation Radar (PR) data were overlaid on a GOES-East satellite infrared/visible image taken at 1626 UTC (12:26 p.m. EDT). The TMI instrument showed very heavy rainfall around Arthur's center. The heaviest rainfall was occurring at a rate of about 2 inches per hour. Powerful thunderstorms in that area reached heights above 15.5 km (about 9.6 miles).
Shortly after TRMM flew over Arthur and gathered rainfall and cloud height data, NASA's Terra satellite captured a visible image of the storm over the Bahamas. The image, created by the NASA Goddard MODIS Rapid Response Team, used visible data from the Moderate Resolution Imaging Spectroradiometer instrument that flies aboard Terra. The image showed a concentration of powerful storms around the center and northwestern quadrant of the storm. Arthur's western quadrant continued to affect the east coast of Florida.
On July 2 at 8 a.m. EDT (12:00 UTC) the center of Tropical Storm Arthur was near latitude 28.8 north and longitude 79.0 west. That's about 100 miles (160 km east-northeast of Cape Canaveral, Florida and NASA's Kennedy Space Center. Arthur's center is also 275 miles (445 km) south of Charleston, South Carolina.
The National Hurricane Center (NHC) noted that Arthur is moving toward the north near 6 mph (9 kph) and this motion is expected to continue today. A turn toward the north-northeast is expected tonight, July 2, followed by a turn toward the northeast. Maximum sustained winds remain near 60 mph (95 kph). Some strengthening is forecast during the next two days and Arthur is expected to become a hurricane by Thursday, July 3.
NHC noted that Arthur is expected to move east of the east-central coast of Florida today, July 2, pass east of Northeastern Florida tonight, move parallel to the coast of South Carolina on Thursday July 3, and approach the hurricane watch area Thursday night.

NASA sees a weaker Tropical Storm Douglas
2014-07-02
NASA's Aqua satellite captured a picture of Tropical Storm Douglas as it began moving into cooler waters in the Eastern Pacific Ocean. Those cooler waters, coupled with drier air are expected to bring about the storm's demise, according to the National Hurricane Center.
A visible image of Tropical Storm Douglas was taken by the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite on July 1 at 21:20 UTC (5:20 p.m. EDT). The thickest band of thunderstorms appeared over the southern semi-circle of the weakening storm while bands ...
Squid sucker ring teeth material could aid reconstructive surgery, serve as eco-packaging
2014-07-02
Squid tentacles are loaded with hundreds of suction cups, or suckers, and each sucker has a ring of razor-sharp "teeth" that help these mighty predators latch onto and take down prey. In a study published in the journal ACS Nano, researchers report that the proteins in these teeth could form the basis for a new generation of strong, but malleable, materials that could someday be used for reconstructive surgery, eco-friendly packaging and many other applications.
Ali Miserez and colleagues explain that in previous research, they discovered that sharp, tough squid sucker ...
'Green buildings' have potential to improve health of low-income housing residents
2014-07-02
The "green building" trend is often associated with helping the environment by using eco-friendly materials and energy-saving techniques, but these practices are designed to improve people's health, too. Now scientists are reporting evidence that they can indeed help people feel better, including those living in low-income housing. Published in ACS' journal Environmental Science & Technology, the study found that certain health problems of public housing residents who moved into green buildings noticeably improved.
Gary Adamkiewicz, Meryl Colton and colleagues note that ...
Toward a new way to keep electronics from overheating
2014-07-02
Computer technology has transformed the way we live, but as consumers expect ever more from their devices at faster speeds, personal computers as well as larger electronic systems can overheat. This can cause them to slow down, or worse, completely shut down. Now researchers are reporting in the ACS journal Industrial & Engineering Chemistry Research that liquids containing nanoparticles could help devices stay cool and keep them running.
Rahman Saidur and colleagues point out that consumers demand a lot out of their gadgets. But that puts a huge strain on the tiny parts ...

Becoming an expert takes more than practice
2014-07-02
Deliberate practice may not have nearly as much influence in building expertise as we thought, according to research published in Psychological Science, a journal of the Association for Psychological Science.
Scientists have been studying and debating whether experts are "born" or "made" since the mid-1800s. In recent years, deliberate practice has received considerable attention in these debates, while innate ability has been pushed to the side, due in part to the famous "10,000-hour rule" coined by Malcolm Gladwell in his 2008 book Outliers.
The new study, from psychological ...
Joslin scientists identify process that affects fat distribution and metabolic syndrome
2014-07-02
BOSTON – July 1, 2014 – Building upon their earlier research on the biology of fat metabolism, Joslin scientists discovered that microRNAs –small RNA molecules that play important roles in regulation in many types of tissue – play a major role in the distribution and determination of fat cells and whole body metabolism. Also, the study is the first to reveal that microRNAs (miRNAs) influence the development of lipodystrophy (abnormal fat accumulation) which affects many people with HIV receiving anti-retroviral therapy. The findings appear in the August issue of the Journal ...
UH researchers identify one of world's thinnest piezoelectric materials
2014-07-02
HOUSTON, July 1, 2014 – There are a handful of naturally occurring materials, known as piezoelectric materials, that generate electricity if you bend, stretch or apply another mechanical force to them, and vice versa – if you apply a voltage across them, they'll deform accordingly. These materials are currently the subject of intense research for their potential applications in energy harvesting, artificial muscles and sensors, among others. These materials are also used in everyday devices, such as loudspeakers, which rely on piezoelectrics to convert electrical signals ...

2014-07-02
This news release is available in Spanish.
This research studies the presence and visibility of the gay world in Spanish cinema between 1940 and 1975. The report, published in the journal Zer by Alejandro Melero, professor in the UC3M Department of Journalism and Audiovisual Communication, shows that there were genres that homosexuality appeared in more frequently. One such genre is comedy, in which it was very usual to portray gays as funny characters.
Beyond our borders—and in sharp contrast to Spanish cinema—directors like Alfred Hitchcock were forerunners in ...
