A collaborative team of scientists from the US and Australia has named a new plant species from the remote Outback. Bucknell University biology postdoctoral fellow Angela McDonnell and professor Chris Martine led the description of the plant that had confounded field biologists for decades because of the unusual fluidity of its flower form.
Repeat coral bleaching caused by rising sea temperatures has resulted in lasting changes to fish communities, according to a new long-term study in the Seychelles.
Large predator fish such as snappers and very small fish such as damselfish dramatically reduced in number and were largely replaced by seaweed-loving fish like rabbitfish.
PHILADELPHIA - It's no secret that Americans are politically divided, but a new report offers hope that Democrats and Republicans find common ground on at least one issue: the role of "evidence" in developing and shaping health laws. Strong bipartisan support exists for a greater use of "evidence" - defined as information based on reliable data and produced by statistical methods - in development of health policy in the United States. The study is published today in Translational Behavioral Medicine from a researcher at Drexel University's Dornsife School of Public Health.
NEW YORK (June 18, 2019) -- Large numbers of healthcare workers risk transmitting respiratory viruses to patients and co-workers by attending work even when they have symptoms, according to a study published today in Infection Control & Hospital Epidemiology, the journal for the Society for Healthcare Epidemiology of America. The study found that 95 percent of people working in healthcare settings have worked while sick, most often because the symptoms were mild or started during their workday.
A new study in the Faculty of Public Health's Journal of Public Health finds that tobacco and alcohol usage are extremely common in British reality television shows.
Terminally ill patients who request that physicians make decisions on their behalf are more likely to receive aggressive treatments in the weeks before they die, according to a Rutgers study.
The study, published in the Journal of Pain and Symptom Management, is the first to examine if personal beliefs and attitudes of both patients and physicians affect end-of-life treatments that can be painful and risky.
Government policy and infrastructure have a substantial impact on hospitalization of older adults, according to a University of Waterloo study.
The study examined the experiences of 254,664 patients in home-care programs and 162,045 residents in long-term care in Alberta, British Columbia and Ontario.
As Charles Darwin wrote in at the end of his seminal 1859 book On the Origin of the Species, "whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved." Scientists have since long believed that the diversity and range of forms of life on Earth, provide evidence that biological evolution spontaneously innovates in an open-ended way, constantly inventing new things.

Geospatial scientists have developed a new program to monitor street signs needing replacement or repair by tapping into Google Street View images.
The fully-automated system is trained using AI-powered object detection to identify street signs in the freely available images.
Municipal authorities currently spend large amounts of time and money monitoring and recording the geolocation of traffic infrastructure manually, a task which also exposes workers to unnecessary traffic risks.
Singapore, 18 June 2019 - How dormant neural stem cells in fruit flies are activated and generate new neurons is described in a new research study by Duke-NUS Medical School. The findings could potentially help people with brain injury or neuronal loss, if similar mechanisms apply in humans.
Bad news, Jurassic Park fans--the odds of scientists cloning a dinosaur from ancient DNA are pretty much zero. That's because DNA breaks down over time and isn't stable enough to stay intact for millions of years. And while proteins, the molecules in all living things that give our bodies structure and help them operate, are more stable, even they might not be able to survive over tens or hundreds of millions of years. In a new paper published in eLife, scientists went looking for preserved collagen, the protein in bone and skin, in dinosaur fossils.
Adequate intake of protein is associated with a reduced risk of frailty and prefrailty in older women, according to a new study from the University of Eastern Finland and Kuopio University Hospital. Adequate protein intake was defined as at least 1.1 g per kg of body weight. The findings were published in European Journal of Nutrition.
Scientists in the FinnBrain research project of the University of Turku, Finland, discovered that the gut microbes of a 2.5-month-old infant are associated with the temperament traits manifested at six months of age. Temperament describes individual differences in expressing and regulating emotions in infants, and the study provides new information on the association between behaviour and microbes. A corresponding study has never been conducted on infants so young or in the same scale.
Researchers have developed a new class of drugs to tackle a common hereditary kidney disease
The disease affects 12 million people worldwide
The compound tested successfully in cell lines cultured from kidney patients
Scientists from the University of Sheffield are part of an international collaboration to develop a new class of drugs to treat a common genetic kidney disease which is a major cause of kidney failure.
