Boston - Data has historically shown that the majority of patients insured through Medicaid, as well as the uninsured, seek inpatient hospital care and services at safety-net hospitals. The Affordable Care Act expanded Medicaid to increase access to public insurance options for low-income individuals and families, as well as improve access to specialty medical care services. Results of a new study led by researchers at Boston Medical Center (BMC) show, however, that this expansion did not lead patients receiving care at safety-net hospitals to transfer their care to non-safety-net hospitals. Published in JAMA Network Open, the national data review showed that discharges from safety-net ...

Maunakea and Haleakala, Hawai'i - Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is heavy, "packing a mass greater than that of our Sun into a body about the size of our Moon," says Ilaria Caiazzo, the Sherman Fairchild Postdoctoral Scholar Research Associate in Theoretical Astrophysics at Caltech and lead author of the new study appearing in the July 1 issue of the journal Nature. "It may seem counterintuitive, but smaller white dwarfs happen to be more massive. This is due to the fact that white dwarfs lack the nuclear burning that keep up normal stars against their own self gravity, and their size is ...

Tokyo, Japan - Believe it or not, steel has something in common with bacterial appendages: they can both undergo a special type of physical transformation that remains puzzling. Now, researchers from Japan and China have used direct microscopic observations to provide more clarity to how this transformation occurs. In a study recently published in Nature Communications, researchers from The University of Tokyo Institute of Industrial Science and Fudan University Department of Physics have revealed previously unknown physical details that underpin crystalline solid-to-solid phase transitions in soft materials, ...

Japanese and Zambian scientists have shown that environmental lead poisoning in children affects not only their own health and wellbeing, but the vitality and mental health of their mothers, as well. Lead poisoning is a common pediatric problem caused by the environment, and is easily preventable. Due to their smaller size and mass, infants and children are at a higher risk of negative effects compared to adults. Chronic lead poisoning leads to fatigue, sleeping problems, headaches, stupor, and anemia. The population of Kabwe, Zambia, is exposed ...

One of the many challenges for grape growers posed by climate change is the accelerated rate at which grapes ripen in warmer climates, which can result in poor colour and aroma development. In a new study published in the Journal of Agricultural and Food Chemistry, researchers from the University of Adelaide found it is possible to increase the flavour potential of Cabernet Sauvignon grapes by slowing down the ripening process with strategies including crop load manipulation and irrigation management. Lead author, Pietro Previtali from the University of Adelaide's School of Agriculture, Food and Wine, said: "Advanced maturation due to warmer temperatures is a key issue for grape growers in most wine regions worldwide and especially in warm ...

Politicians use emotional resources in their speeches in parliament depending on the type of debate and use emotive rhetoric strategically and selectively, mainly to attract voters. This is one of the main conclusions of a study published in the journal American Political Science Review (APSR) involving Toni Rodon, a professor with the UPF Department of Political and Social Sciences and member of the Research Group on Institutions and Political Actors, together with Moritz Osnabrügge (Durham University, as first author) and Sara B. Hobolt (London School of Economics and Political Science). "Our research provides evidence that incentives to attract voters differ systematically depending on the type of debate" In recent years, much research has been done ...

Domestic burning of wood and dung fuels in Neolithic homes would have exceeded modern internationally-agreed standards for indoor air quality, exposing inhabitants to unsafe levels of particulates. Working with environmental engineers, archaeologists at Newcastle University, UK, used modern air quality monitoring methods to assess the impact of domestic fuel burning inside buildings at Çatalhöyük, in Turkey, one of the world's earliest settlements. A typical house at Çatalhöyük, a UNESCO World Heritage site, had a domed oven set against the south wall, located beneath an opening in the roof. In the 1990s, a replica of one of these houses ...

Reactive oxygen species (ROS) are highly reactive chemicals which contain oxygen radicals. Hypochlorous acid, peroxides, superoxide, singlet oxygen, alpha-oxygen and hydroxyl radicals are the major examples of ROS, which are familiar to persons from many walks of life as they are used in many domestic and industrial processes. ROS are naturally produced during a variety of biochemical reactions within the cell organelles such as the endoplasmic reticulum, mitochondria and peroxisomes. ROS are also formed as a byproduct of the normal metabolism of oxygen. The production of ROS can be induced by various factors such as heavy metals, tobacco, smoke, drugs, xenobiotics, pollutants and radiation. From various experimental studies, it is reported that ROS acts as either tumor suppressing or tumor ...
