Bleaching events caused by rising water temperatures could increase mortality among a coral species already threatened by disease, says new research by Mote Marine Laboratory and Penn State, US, published in eLife.
The study on the species Acropora cervicornis, known as the staghorn coral, emphasizes the need for maintaining genetic diversity while at the same time increasing resilience within the species, as part of restoration efforts to help prevent further loss in the Florida region.
Giving up a kidney to a stranger requires a certain sense of selflessness, what's come to be known in social science as extraordinary altruism. University of Pennsylvania psychologist Kristin Brethel-Haurwitz wanted to understand the connection between this trait and empathy, specifically empathy for distress emotions.
Shame on you. These three simple words can have devastating effect on an individual's psyche.
But why is that? How is the feeling of shame generated, and what is its purpose? Some theorists argue that feeling shame is a pathology, a condition to be cured. Others dismiss it as a useless, ugly emotion.
Doctors and nurses often prescribe antibiotics for children with cough and respiratory infection to avoid return visits, symptoms getting worse or hospitalisation. In a study published in the British Journal of General Practice today [Tuesday 11 September], researchers from the Universities of Bristol, Southampton, Oxford and Kings College London found little evidence that antibiotics reduce the risk of children with cough ending up in hospital, suggesting that this is an area in which unnecessary antibiotic prescribing could be reduced.
PITTSBURGH-- Researchers at Carnegie Mellon University have devised a way to automatically transform the content of one video into the style of another, making it possible to transfer the facial expressions of comedian John Oliver to those of a cartoon character, or to make a daffodil bloom in much the same way a hibiscus would.
On Sept. 9, 2018, NASA's Solar Dynamics Observatory, SDO, saw two lunar transits as the Moon passed in front of the Sun. A transit happens when a celestial body passes between a larger body and an observer. This first lunar transit lasted one hour, from 4:30 pm to 5:30 p.m. EDT and obscured 92 percent of the Sun at the peak of its journey. The second transit happened several hours later at 9:52 p.m. and lasted a total of 49 minutes, ending at 10:41 p.m. EDT. This transit only obscured 34 percent of the Sun at its peak.
Shifting to a healthy diet is not only good for us, but it also saves a lot of precious fresh water, according to a new study by the JRC published in Nature Sustainability.
Compared to existing diets, the water required to produce our food could be reduced by between 11% and 35% for healthy diets containing meat, 33% and 55% for healthy pescetarian diets and 35% and 55% for healthy vegetarian diets.
Obesity leads to cognitive impairment by activating microglial cells, which consume otherwise functional synapses in the hippocampus, according to a study of male mice published in JNeurosci. The research suggests that microglia may be a potential therapeutic target for one of the lesser known effects of this global health epidemic on the brain.
Acute critical illness in people without previous renal disease puts them at risk of kidney complications as well as death, according to a study in published in CMAJ (Canadian Medical Association Journal).
Half of over-65s suffer from dizziness and problems with balance. But some tests to identify the causes of such problems are painful and can risk hearing damage. Now, researchers from Chalmers University of Technology, Sweden, have developed a new testing device using bone conduction technology, that offers significant advantages over the current tests.
CHICAGO, Sept 8, 2018 -- Men and women with high blood pressure reduced the need for antihypertensive medications within 16 weeks after making lifestyle changes, according to a study presented at the American Heart Association's Joint Hypertension 2018 Scientific Sessions, an annual conference focused on recent advances in hypertension research.
Lifestyle changes are the first step in reducing blood pressure according to the 2017 American College of Cardiology/American Heart Association Hypertension Guideline.
SALT LAKE CITY -- Few treatments exist for neurodegenerative diseases that progressively rob a person's ability to move and think, yet the results of a new study could potentially open additional approaches for exploration.
Jet-air hand dryers in hospital toilets spread more germs than disposable paper towels and should not be used, say researchers.
Writing in the Journal of Hospital Infection, they argue that the official guidance about how to prevent bacterial contamination in hospital buildings needs to be strengthened.
At the moment, the official Department of Health guidance says air dryers can be placed in toilets in the public areas of a hospital but not in clinical areas: not because of the risks they pose for cross contamination but because they are noisy.
ARLINGTON HEIGHTS, IL (September 7, 2018) - If you and your doctor chat for a few minutes about treatment options for your allergy symptoms, is that considered shared decision-making (SDM)? It is not, according to a new article published in Annals of Allergy, Asthma and Immunology, the scientific publication of the American College of Allergy, Asthma and Immunology (ACAAI).
