(Press-News.org) NASA-NOAA's Suomi NPP satellite captured an image of the remnants of Tropical Cyclone Nathan over the southern Top End of Australia's Northern Territory on March 25.
On March 25, the Australian Bureau of Meteorology (ABM) issued a Severe Weather Warning for heavy rainfall for people in the Daly, Arnhem, Carpentaria and Gregory forecast districts of Top End. The Top End contains the region's capital city of Darwin, and is home to Kakadu National Park, the country's largest national park.

When Suomi NPP passed over Nathan on March 25 at 4:49 UTC (12:49 a.m. EDT) the Visible Infrared Imaging Radiometer Suite or VIIRS instrument aboard captured a visible image of the storm.
VIIRS is a scanning radiometer that collects visible and infrared imagery and "radiometric" measurements. Basically it means that VIIRS data is used to measure cloud and aerosol properties, ocean color, sea and land surface temperature, ice motion and temperature, fires, and Earth's albedo (reflected light). The Suomi NPP mission is a bridge between NOAA and NASA legacy Earth observing missions and NOAA's next-generation Joint Polar Satellite System, or JPSS.
The VIIRS image showed that the storm had basically unraveled and the bulk of clouds associated with the remnant low were southeast of the center. At 10:44 p.m. CST local time, the ABM noted that Ex-Tropical Cyclone Nathan was over the northern Daly District, just south-southwest of Darwin.
ABM noted two large rainfall totals that occurred in 24 hours as of 9 a.m. local time CST included 10.2 inches (261 mm) at Fanny Creek and 8.1 inches (208 mm) at Snowdrop Creek.
The remnant low is expected to move west into Timor Sea by early Thursday, March 26 (local time).

Getting a good education may not improve your life chances of happiness, according to new mental health research from the University of Warwick.
In a new study published in the British Journal of Psychiatry, researchers from Warwick Medical School examined socioeconomic factors related to high mental wellbeing, such as level of education and personal finances.
Low educational attainment is strongly associated with mental illness but the research team wanted to find out if higher educational attainment is linked with mental wellbeing.
The team found all levels of ...
Mobile devices have a large number of different adjustable system settings whose energy impact can be difficult to understand for the average user, and even for the expert.
Some system settings have a direct and significant correlation with energy consumption, for example screen brightness and network connectivity. The energy impact of system settings and their combinations, such as the combination of roaming, high operating temperature, and bad signal strength, are much more difficult to predict. The research article by the Finnish computer scientists demonstrates that ...
An analysis conducted by researchers at the Johns Hopkins Center for a Livable Future (CLF) found that the risks of drinking raw (unpasteurized) cow's milk are significant. Consumers are nearly 100 times more likely to get foodborne illness from drinking raw milk than they are from drinking pasteurized milk. In fact, the researchers determined that raw milk was associated with over half of all milk-related foodborne illness, even though only an estimated 3.5% of the U.S. population consumes raw milk.
Based on their findings, the researchers discourage the consumption ...
DETROIT - Co-existing psychiatric illness should be considered in assessing hospital readmissions for three common medical conditions used by Medicare and Medicaid to penalize hospitals with "excessive" readmission rates.
That was the conclusion of a newly published collaborative study by 11 major U.S. healthcare providers - including Henry Ford Health System - affiliated with the nationwide Mental Health Research Network (MHRN).
The study is published in Psychiatric Services.
The subject of readmission rates has been of increasing concern to U.S. hospitals since ...
Scientists at Columbia University's Mailman School of Public Health report that children with autism spectrum disorder (ASD) were two-and-a-half times more likely to have persistent gastrointestinal (GI) symptoms as infants and toddlers than children with typical development. Results are published in JAMA Psychiatry.
The study is based on a large longitudinal survey of Norwegian mothers who were asked about their child's GI disturbances during the first three years of life. Questionnaires were completed when the children were 18 and 36 months of age.
The authors ...
Gastrointestinal symptoms reported by mothers were more common and more often persistent in the first three years of life in children with autism spectrum disorder than in children with typical development and developmental delay, according to an article published online by JAMA Psychiatry.
Autism spectrum disorders (ASDs) are characterized by problems in social communication and interaction, as well as restricted/repetitive behaviors. Medical and psychiatric conditions are frequently associated with ASD and among the most common are gastrointestinal (GI) symptoms and ...
A new analysis of surgical outcomes nationwide concludes that more use of minimally invasive surgery for certain common procedures can dramatically reduce post-operative complications and shave hundreds of millions of dollars off the nation's health care bill.
Results of the research, conducted by Johns Hopkins investigators and published March 25 in JAMA-Surgery, indicate that American hospitals collectively could prevent thousands of post-surgical complications and save between $280 million and $340 million a year by using more minimally invasive procedures instead ...
A small imaging study suggests prenatal exposure to polycyclic aromatic hydrocarbons (PAHs), the toxic air pollution caused in part by vehicle emissions, coal burning and smoking, may be bad for children's brains and may contribute to slower processing speeds and behavioral problems, including attention-deficit-hyperactivity-disorder (ADHD) symptoms, according to an article published online by JAMA Psychiatry.
PAHs are caused by the incomplete combustion of organic materials. In addition to outdoor air pollution, sources of indoor air pollution caused by PAHs can be cooking, ...
A variety of dialectical behavior therapy (DBT) interventions helped to reduce suicide attempts and nonsuicidal self-injury acts in a randomized clinical trial of women with borderline personality disorder who were highly suicidal, according to an article published online by JAMA Psychiatry.
DBT is a multicomponent therapy for individuals at high risk for suicide and for those with multiple severe mental disorders, particularly those who have marked impulsivity and an inability to regulate emotions. The components of DBT include individual therapy, group skills training, ...
Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine. This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain. The research is important as currently 98% of therapeutic molecules are also unable to cross the blood-brain barrier. "The barrier is temporary opened at a desired location for approximately 2 hours by a small elevation of the temperature ...
