WASHINGTON --When older adults in severely debilitated states show up for treatment in the emergency department, emergency physicians and staff must be able to identify and document their symptoms and decide whether to report their concerns to adult protective services. This is a difficult decision as the patient's symptoms may stem from willful neglect, unintentional neglect or sub-acute symptoms caused by an underlying illness than manifest as neglect. Two papers published online last Friday in Annals of Emergency Medicine highlight a problem that promises to grow rapidly with the aging of the Baby Boom generation.

The signatory countries of the Kyoto Protocol and the newer Paris Agreement have committed to reduce global warming, but they can only use estimates and projections to verify whether they are actually achieving the necessary reduction in greenhouse gases.

The uncertainties are considerable and mistakes do happen.

Researchers funded by the Swiss National Science Foundation (SNSF) have developed a method to independently monitor these statistics by making direct measurements of the gases in the atmosphere.

Commonly used antidepressants, known as 'selective serotonin reuptake inhibitors', are not associated with an increased risk of cardiovascular conditions, such as heart attacks and strokes, according to new research at The University of Nottingham.

Depression is known to increase the risk of cardiovascular problems, but whether antidepressants, particularly SSRIs, increase or reduce this risk remains controversial.

The results are significant because antidepressants are one of the most commonly prescribed drugs and cardiovascular diseases are a leading cause of death and disability worldwide.

Today, at the Microbiology Society's Annual Conference in Liverpool, scientists will show that the foam made by Trinidadian frogs represents a new, non-toxic antibiotic delivery system that may help to prevent infections.

While mating, Tungara frogs (Engystomops pustulosus) release a protein cocktail that they beat into a foam with their back legs. The frogs - less than 5 centimetres long - lay their eggs in these foam nests to protect them from disease, predators and environmental stresses.

Current climate models are too simplistic to really account for all of the factors in climate in the present, much less predict the future, but they are being used by policy makers to anticipate the effects of greenhouse gases as far out as a hundred years so it is important they gradually converge on accuracy before too much money is spent.

Today, at the Microbiology Society's Annual Conference, scientists discussed one missing piece of the puzzle in computer simulations - Arctic microbes that are increasing the rate at which glaciers melt.

High-intensity 'sprint training' may be gaining popularity at gyms, but if you're new to this form of exercise, the workout could do more harm than good.

A study by Canadian and European researchers found signs of stress in the muscle tissues of their non-athlete, untrained subjects after ultra-intense leg and arm cycling exercises. Perhaps more concerning, researchers reported the untrained subjects had a weakened ability to fight off free radicals, molecules that can alter DNA and harm healthy cells.
