Researchers at the University of Waterloo have found that sentiments in the nursing notes of health care providers are good indicators of whether intensive care unit (ICU) patients will survive.

Hospitals typically use severity of illness scores to predict the 30-day survival of ICU patients. These scores include lab results, vital signs, and physiological and demographic characteristics gathered within 24 hours of admission.

Prison employees experience PTSD on par with Iraq and Afghanistan war veterans, a new study from a Washington State University College of Nursing researcher found.

Working conditions in a prison can include regular exposure to violence and trauma, and threats of harm to the workers and their families. Previous studies have shown that prison workers have some of the highest rates of mental illness, sleep disorders and physical health issues of all U.S. workers. But the rate of PTSD among prison workers isn't well understood.

A garden can be a competitive environment. Plants and unseen microorganisms in the soil all need precious space to grow. And to gain that space, a microbe might produce and use chemicals that kill its plant competitors. But the microbe also needs immunity from its own poisons.

CHAMPAIGN, Ill. -- A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer's growth and spread, University of Illinois researchers report in a new study in mice. The molecules, called endocannabinoids, are made naturally by the body and have similar properties to cannabinoids found in marijuana - but without the psychotropic effects.

MIAMI--Scientists have confirmed for the first time that radical changes of one volcano in southern Japan was the direct result of an erupting volcano 22 kilometers (13.7 miles) away. The observations from the two volcanos--Aira caldera and Kirishima--show that the two were connected through a common subterranean magma source in the months leading up to the 2011 eruption of Kirishima.

UPTON, NY--Theoretical physicists at the U.S. Department of Energy's (DOE's) Brookhaven National Laboratory and their collaborators have just released the most precise prediction of how subatomic particles called muons--heavy cousins of electrons--"wobble" off their path in a powerful magnetic field. The calculations take into account how muons interact with all other known particles through three of nature's four fundamental forces (the strong nuclear force, the weak nuclear force, and electromagnetism) while reducing the greatest source of uncertainty in the prediction.

New research has revealed for the first time what impact cutting back on drinking and smoking as a population would have on Australia's cancer death rate.

Researchers from the Centre for Alcohol Policy Research (CAPR), La Trobe University, found reducing tobacco and alcohol consumption rates as a nation would significantly reduce future cancer deaths.

The researchers used health and consumer data dating back to the 1930s to establish the link between population-level smoking and drinking rates and cancer mortality.

American media is grappling with an image problem. Accusations of "fake news," foreign companies meddling in Facebook's data and a further polarization of how the Fourth Estate should operate in the digital age have turned journalistic ethics into a common talking point on the evening news.

Rats take a fundamentally different approach toward solving a simple visual discrimination task than tree shrews, monkeys, and humans, according to a comparative study of the four mammal species published in eNeuro. The work could have important implications for the translation of research in animal models to humans.

Army ant (Eciton) soldiers are bigger but do not have larger brains than other workers within the same colony that fulfill more complex tasks, according to a study published in the open access journal BMC Zoology. A collaborative team of researchers led by Drexel University in Philadelphia, US and German colleagues suggests that because the very specific and limited tasks soldiers fulfill place limited cognitive demands on them, investment in the development of brain tissue is also limited.
