Psychology surveys have found that when people go to bed and thus how long they sleep at a time might actually make it difficult for people to stop worrying.

The surveys showed that people who sleep for shorter periods of time and go to bed very late at night often have more negative thoughts than those who keep regular sleeping hours.  

Alzheimer's disease progresses inside the brain as deposits of the toxic protein amyloid-beta (Aβ),overwhelm neurons. A side effect of accumulating Aβ in neurons is the fragmentation of the Golgi apparatus, the part of the cell involved in packaging and sorting protein cargo including the precursor of Aβ. Or it may be the other way around and loss of Golgi function is a driving force behind Alzheimer's.

Yanzhuang Wang, Gunjan Joshi, and colleagues at the University of Michigan, Ann Arbor, set out to uncover the mechanism damaging the Golgi using a transgenic mouse and tissue culture models of 
Alzheimer's disease
to look at what was going on. 

Epidemiologists have examined the relationship between body weight and life expectancy and say that overweight and obese individuals have the potential to decrease life expectancy by up to 8 years.

If diabetes or cardiovascular disease develop, that could shorten life expectancy ever more, according to their analysis of data from the National Health and Nutrition Examination Survey (years 2003 to 2010) which was used to estimate the annual risk of diabetes and cardiovascular disease in adults with different body weights.

The data from almost 4,000 individuals was also used to analyze the contribution of excess body weight to years of life lost and healthy years of life lost. 

A new technique involves wrapping chemotherapy drugs in a liposome - a fatty cover - and it reduces heart damage that would otherwise occur, according to a presentation by Professor Jutta Bergler-Klein and Professor Mariann Gyöngyösi from the Medical University of Vienna, at
EuroEcho-Imaging 2014.

The Obamacare website is not the only thing that debuted incomplete, buggy, difficult to use and nonetheless mandated. The Open Payments Program database, also known as the Physician Payments Sunshine Act, was 12 years in the making and designed to report drug and device industry payments to physicians, but it came onto the scene with a resounding thud, burdensome to most and helping almost no one. But it is too important to dismiss before its shortcomings are addressed, say the authors of a Viewpoint in JAMA.

In the last 20,000 years, Europeans and Asians became numerous and their descendants now comprise the bulk of our 7 billion population. Prior to that, for 130,000 years, the Khoisan (they call themselves Bushmen), of Namibia reigned supreme.

Their lifestyles remain relatively primitive. And genetically, they have not changed all that much either. They number only about 100,000 and a study in Nature Communications compared nearly all the genes of these individuals -- their genomes -- with the genomes of people from around the world, and discovered that the inflow of new genes into the Bushmen has been quite restricted the past 150,000 years.
