Examples of poisonings due to people mistakenly picking and consuming poisonous botanicals in the wild made it clear that, contrary to claims by an alarming number of nutritionists and supplement sales compnies, natural does not mean safe.

Nature has always been just as toxic as any synthetic chemical and people being sold botanicals need public awareness, and they won't get it from the people making money off of their lack of knowledge.

When health problems occur, medical professionals also need better awareness of negative health consequences related to consuming certain botanicals – both acute effects and adverse effects due to prolonged use – to ensure such effects can be reported and factored into risk assessments.

For some Medicare patients, the prognosis was better when cardiologists were away from the hospital attending national cardiology meetings.

Anupam B. Jena, M.D., Ph.D., of Harvard Medical School, Boston, and coauthors analyzed differences in 30-day mortality and treatment such as angioplasty (also known as percutaneous coronary intervention, PCI) among Medicare patients hospitalized for heart attack (acute myocardial infarction, AMI), heart failure or cardiac arrest from 2002 to 2011 during the dates of two national cardiology meetings compared with identical non-meeting dates in the three weeks before and after conferences.  

Scam artists often prey on older people and that has fed the perception that when it comes to important financial decisions, getting old means having less competence.

Not so, according to new work using credit scores and cognitive ability tests, which instead found evidence that "crystallized intelligence" - gained through experience and accumulated knowledge - is more important that "fluid intelligence," the ability to think logically and process new information.

Past research has found that fluid intelligence decreases with old age and so being a senior citizen means being resigned to "cognitive decline."

Being obese brings with it a greater risk of heart disease, but patients who are obese before developing heart failure live longer than normal weight patients with the same condition, an 'obesity paradox' that is still unexplained.

Using data from the Atherosclerosis Risk in Communities Study, researchers looked at body mass index before the initial diagnosis of heart failure in 1,487 patients and followed them for 10 years, comparing the survival rates of obese, overweight and normal weight patients after the development of heart failure. The majority of patients included in the study were overweight (35 percent) or obese (47 percent) prior to their initial diagnosis of heart failure.

Use of a light-emitting electronic device like an iPad in the hours before bedtime can adversely impact overall health, alertness, and the circadian clock which synchronizes the daily rhythm of sleep to external environmental time cues, according to a new study which compared the biological effects of reading an light-emitting electronic device (LE-eBook) to a printed book. 

An oil palm system model based on the Agricultural Production Systems Simulator (APSIM) framework and called APSIM Oil Palm is aimed at helping growers of the crop maximize the yields of their plantations, while minimizing detrimental environmental impacts.  

"Oil palm has become a major crop in the tropics, cultivated on more than 39 million acres of land," co-author Dr Paul Nelson of James Cook University said. "Demand for the product continues to grow, and the industry is expected to keep expanding in the foreseeable future. At the same time, there is significant concern about the industry's environmental impacts, with many purchasers wanting only certified sustainable palm oil.
