NASA sees Nathan weakening near Darwin, Australia
2015-03-24
(Press-News.org) Tropical Cyclone Nathan has been weakening as it continued to move over land in Australia's Northern Territory on March 24. NASA's Aqua satellite captured a visible picture of the storm over land. Just one day before the Tropical Rainfall Measuring Mission satellite saw some heavy rainfall in Nathan.
The Tropical Rainfall Measuring Mission (TRMM) satellite captured rainfall rate and cloud height data when it passed above Nathan on March 23, 2015 at 0631 UTC (2:31 a.m. EDT) before Nathan moved inland. Nathan had intensified and had hurricane force winds of about 65 knots (75 mph). TRMM's Precipitation Radar (PR) data showed that Nathan had a few areas of very heavy precipitation along Australia's Arafura Sea coast. TRMM's Precipitation Radar (PR) found that the tops of a few thunderstorms in intense rain bands rotating around Nathan's northwestern side reached heights above 15.5 km (9.6 miles).
On March 24 at 05:20 UTC (1:20 a.m. EDT), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Nathan over the Top End of the Northern Territory, Australia. The storm appeared elongated with a concentration of strongest storms near the center, and a band of thunderstorms around the northwestern periphery.
The Joint Typhoon Warning Center (JTWC) issued the final warning on Tropical Cyclone Nathan today, March 24 at 0900 UTC (5 a.m. EDT). The Australian Bureau of Meteorology (ABM) noted Ex-Tropical Cyclone Nathan was moving across the northwest Arnhem district. The remnant tropical low is expected to track toward the west toward the Southern Indian Ocean.
ABM noted that Nathan's remnants will generate thunderstorms with gusty winds and heavy rainfall which may lead to flash flooding in the southern Arnhem forecast district and extending to parts of the Daly forecast district on Wednesday, March 25. ABM stated that locations that may be affected include Douglas River, Nauiyu, Peppimenarti, Barunga, Beswick, Bulman, Central Arnhem Plateau, Ngukurr, Numbulwar and Litchfield National Park.

Nathan's maximum sustained winds dropped to 30 knots (34.5 mph/55.5 kph) as it continued to move across land in the Top End of Australia's Northern Territory. Nathan was centered near 12.5 south latitude and 132.4 east longitude, just 88 nautical miles (101.3 miles/163 km) east of Darwin, Australia. It was moving to the west-southwest at 7 knots (8 mph/12.9 kph).
Today, March 24, Nathan continues weakening inland and adverse conditions will prevent re-strengthening over the next few days as the remnant low moves. There is some potential for regeneration by the end of the week once it moves into the Southern Indian Ocean.

COLUMBIA, Mo. - The Ultimate Fighting Championship (UFC), a mixed martial arts league, has experienced large growth in popularity and economic success in recent years. UFC has achieved this success by marketing to fans who attend live fighting events and who purchase Pay Per View (PPV) options to watch UFC events on television.
Now, a researcher at the University of Missouri has found that fans' interest in the sport and, thus, their desire to spend money differs based on the venue. Nicholas Watanabe, an assistant professor of sport management in the MU Department of ...

Children as young as 5 years old are less likely to help a person in need when other children are present and available to help, according to new research published in Psychological Science, a journal of the Association for Psychological Science.
"The children in our study helped at very high levels only when responsibility was clearly attributable to them," explains psychological scientist and lead researcher Maria Plötner of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. "These findings suggest that children at this age take responsibility ...

The recent Ebola outbreak highlighted the challenges to governments and local public health authorities in determining when individuals or populations should be subjected to quarantine. While one state or country can legally enact such laws, others may not. In many instances unintended negative consequences have resulted, and the ensuing chaos has led to major frustration both for patients and medical staff, as well as for local authorities.

WASHINGTON, D.C., March 24, 2015 -- Move over, vapor compression cooling technology. Emerging "elastocaloric" refrigeration is potentially much more efficient and, unlike vapor compression, relies on environmentally-friendly refrigerants.
In elastocaloric materials a change in mechanical stress can create a change in temperature.
In the Journal of Applied Physics, from AIP Publishing, a team of researchers from Technical University of Denmark report that the elastocaloric effect opens the door to alternative forms of solid-state refrigeration that are direct replacements ...

WASHINGTON D.C., March 24, 2015 - Attempting to develop a novel type of permanent magnet, a team of researchers at Trinity College in Dublin, Ireland has discovered a new class of magnetic materials based on Mn-Ga alloys.
Described as a zero-moment half metal this week in the journal Applied Physics Letters, from AIP Publishing, the new Mn2RuxGa magnetic alloy has some unique properties that give it the potential to revolutionize data storage and significantly increase wireless data transmission speeds.
The discovery realizes a goal researchers have sought for several ...

Among patients with symptomatic intracranial arterial stenosis (narrowing of an artery inside the brain), the use of a balloon-expandable stent compared with medical therapy (clopidogrel and aspirin) resulted in an increased of stroke or transient ischemic attack (TIA), according to a study in the March 24/31 issue of JAMA.
Intracranial arterial stenosis is a common cause of stroke worldwide. The recurrent stroke risk with severe symptomatic intracranial stenosis may be as high as 23 percent at 1 year, despite medical therapy, according to background information in the ...

An analysis of the trends in salaries of registered nurses (RNs) in the United States from 1988 through 2013 finds that male RNs outearned female RNs across settings, specialties, and positions, with no narrowing of the pay gap over time, according to a study in the March 24/31 issue of JAMA.
Fifty years after the Equal Pay Act, the male-female salary gap has narrowed in many occupations. Yet pay inequality persists for certain occupations, including medicine and nursing. Studies have documented higher salaries for male registered nurses, although analyses have not considered ...

WASHINGTON, D.C., March 24, 2015 - Silicon solar cells dominate 90 percent of the global photovoltaic market today, yet the record power conversion efficiency of silicon photovoltaics has progressed merely from 25 percent to 25.6 percent during the past 15 years -- meaning the industry is keen to explore alternatives.
A collaboration between the Massachusetts Institute of Technology (MIT) and Stanford University may be poised to shake things up in the solar energy world. By exploring ways to create solar cells using low-cost manufacturing methods, the team has developed ...

A multivalent candidate vaccine elicits broad antibody responses to a range of norovirus strains, including strains not included in the vaccine or previously encountered by participants, according to a new study published this week in PLOS Medicine. The results of the study, led by Lisa Lindesmith and Ralph Baric of the University of North Carolina at Chapel Hill, indicate that a vaccine to norovirus may be available in the future.
Worldwide, noroviruses cause one in five cases of viral gastroenteritis. An estimated annual 300 million cases of norovirus infection contribute ...

CAMBRIDGE, Mass--Researchers at MIT and Stanford University have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun's energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations, the researchers say.
The new cell uses a layer of silicon -- which forms the basis for most of today's solar panels -- but adds a semi-transparent layer of a material called perovskite, which can absorb higher-energy particles ...
