Intensifying Hurricane Lane examined by GPM satellite

Jue, 08/16/2018 - 22:00
Heavy rainfall and towering cloud heights were the findings when Hurricane Lane was scanned by the Global Precipitation Measurement mission or GPM core observatory satellite on Aug. 17. Lane strengthened to a Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale.

URI chemistry professor develops contaminant detection technique for heparin

Jue, 08/16/2018 - 22:00
In 2008, a contaminant eluded the quality safeguards in the pharmaceutical industry and infiltrated a large portion of the supply of the popular blood thinner heparin, sickening hundreds and killing about 100 in the US.

UVA multidisciplinary engineering team designs technology for smart materials

Jue, 08/16/2018 - 22:00
With inspiration from squid ring teeth, a multidisciplinary team led by UVA engineers has invented a novel way to manufacture smart materials, including fabrics, that can regulate their own thermal properties.

Researchers find pathways that uncover insight into development of lung cancer

Jue, 08/16/2018 - 22:00
Lung cancer results from effects of smoking along with multiple genetic components. A new study conducted at Dartmouth identifies two main pathways for the role of chromosome 15q25.1--a leader in increasing susceptibility to lung cancer--in modifying disease risk. One pathway is implicated in nicotine dependence. The other plays a part in biological processes such as nutrient transfer and immune system function. The findings increase our understanding of lung cancer cause and development.

Automated detection of focal epileptic seizures in a sentinel area of the human brain

Jue, 08/16/2018 - 22:00
In a first-in-humans pilot study, researchers have identified a sentinel area of the brain that may give an early warning before clinical seizure manifestations from focal epilepsy appear. They have also validated an algorithm that can automatically detect that early warning. These two findings offer the possibility of squelching a focal epilepsy seizure -- before the patient feels any symptoms -- through neurostimulation of the sentinel area of the brain.

NASA's GPM analyzes Atlantic Tropical Storm Ernesto's rainfall

Jue, 08/16/2018 - 22:00
NASA found light to moderate rainfall occurring in Tropical Storm Ernesto as it continued on an eastern trek toward Ireland and the United Kingdom. Ireland has already issued a warning for Ernesto.

Texas A&M team develops new way to grow blood vessels

Jue, 08/16/2018 - 22:00
Formation of new blood vessels, a process also known as angiogenesis, is one of the major clinical challenges in wound healing and tissue implants. To address this issue, researchers from Texas A&M University have developed a clay-based platform to deliver therapeutic proteins to the body to assist with the formation of blood vessels.

Water-worlds are common: Exoplanets may contain vast amounts of water

Jue, 08/16/2018 - 22:00
Scientists have shown that water is likely to be a major component of those exoplanets (planets orbiting other stars) which are between two to four times the size of Earth. It will have implications for the search of life in our Galaxy. The work is presented at the Goldschmidt conference in Boston.

NASA analyzes Typhoon Soulik's water vapor

Jue, 08/16/2018 - 22:00
NASA's Terra satellite looked at water vapor and cloud top temperatures when it passed over the recently strengthened Typhoon Soulik in the Northwestern Pacific Ocean.

Exploring the relationship between fever and cancer incidence

Jue, 08/16/2018 - 22:00
In "Toward Antitumor Immunity and Febrile Infections: Gamma/Delta (γδ) T Cells Hypothesis" published in The Quarterly Review of Biology, Wieslaw Kozak, Tomasz Jedrzejewski, Malgorzata Pawlikowska, Jakub Piotrowski, and Sylwia Wrotek propose a mechanistic hypothesis that focuses on the potential impact infectious fever has on a particular subset of T cells, known as gamma/delta (gd) T cells.

HIV and a tale of a few cities

Jue, 08/16/2018 - 22:00
In a pair of new modeling studies, researchers at University of California San Diego School of Medicine, with international colleagues, examined how policy reform in terms of drug decriminalization (in Mexico) and access to drug treatment (in Russia) might affect two regions hard hit by the HIV pandemic: Tijuana, Mexico and the Russian cities of Omsk and Ekaterinburg.

NASA finds Tropical Storm Bebinca moving over Laos, Thailand

Jue, 08/16/2018 - 22:00
NASA's Aqua satellite found strong storms circling the center of Tropical Storm Bebinca as it moved over northern Laos and into Thailand on Aug. 17.

Scientists deploy damage assessment tool in Laos relief efforts

Jue, 08/16/2018 - 22:00
The July 23 failure of the Xepian-Xe Nam Noy hydropower dam unleashed more than 130 billion gallons of water on rural villages in southern Laos, in Southeast Asia, devastating thousands of houses and businesses and displacing more than 6,000 people. As authorities scrambled to gather information in the wake of the disaster, scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., activated a new tool to help them assess the damage and get help to people in need.

Stroke patients treated at a teaching hospital are less likely to be readmitted

Jue, 08/16/2018 - 22:00
Stroke patients appear to receive better care at teaching hospitals with less of a chance of landing back in a hospital during the early stages of recovery, according to new research from The University of Texas Health Science Center at Houston (UTHealth).

Like shark attack and the lottery, unconscious bias influences cancer screening

Jue, 08/16/2018 - 22:00
Study shows that doctors with personal experience of cancer are more likely to act against established guidelines to recommend that low-risk women receive ovarian cancer screening.

First science with ALMA's highest-frequency capabilities

Jue, 08/16/2018 - 22:00
A team of scientists using the highest-frequency capabilities of the Atacama Large Millimeter/submillimeter Array(ALMA) has uncovered jets of warm water vapor streaming away from a newly forming star. The researchers also detected the 'fingerprints' of an astonishing assortment of molecules near this stellar nursery.

Unexpected future boost of methane possible from arctic permafrost

Jue, 08/16/2018 - 22:00
New NASA-funded research has discovered that Arctic permafrost's expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing. Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms as permafrost thaws.

Three factors could explain physician burnout

Jue, 08/16/2018 - 22:00
In just three years, physician burnout increased from 45.5 percent to 54.4 percent, according to a paper authored by doctors at the University of California, Riverside School of Medicine. They offer three factors that they say contribute to this burnout.

Acid coastal seas off US putting common fish species at risk

Jue, 08/16/2018 - 22:00
Scientists have shown that coastal waters and river estuaries can exhibit unique vulnerabilities to acidification than offshore waters. This acidification, detected in waters off the United States West Coast and the Gulf of Mexico, can lead to disorientation and cognitive problems in some marine fish species, such as salmon, sharks, and cod. This work is presented at the Goldschmidt Conference in Boston
