Recent mass killings in Norway, America and in numerous countries have happened at locations as different as schools, movie theaters, and marathons. Though the actual number of mass killings has not changed in 30 years, they get a lot more attention now.

One trait they all share in common is psychiatric medication but unsurprisingly the biggest focus in a roundtable discussion among film studies scholars, psychiatrists and psychologists in a publication named Violence and Gender
is that they were all young males. The participants speculate about the possible reasons for high incidence of these crimes and the motives of the young male perpetrators.

There is a great deal of interest how cocoa flavanols (a type of antioxidant ) like monomers and procyanidins might prevent obesity and type-2 diabetes, though little is actually known how they might work. 

A new study compared the impacts of long-term dietary exposure to cocoa flavanol monomers, oligomers and polymers on the effects of high-fat feeding. Mice were fed a high-fat diet supplemented with either a cocoa flavanol extract or a flavanol fraction enriched with monomeric, oligomeric, or polymeric procyanidins for 12 weeks. 

The International Peanut Genome Initiative, a multinational group crop geneticists who have been working in tandem for the last several years, have successfully sequenced the genome of 
Arachis hypogaea
 - the peanut. 

Arachis hypogaea and also called groundnut and, of course, peanut, is important both commercially and nutritionally. While the oil- and protein-rich legume is seen as a cash crop in the developed world, it remains a valuable sustenance crop in developing nations. The new peanut genome sequence is available to researchers and plant breeders across the globe to aid in the breeding of more productive and more resilient peanut varieties. 

The inscription on a 3,500-year-old stone may be one of the world's oldest weather reports - and it could cause us to revise our chronology of the ancient Middle East.

Occasionally I’ll come across a web page that shows you how to make an infrared (IR) filter for your iPhone (in my case the iPod Touch) out of an old floppy disk. I had an old floppy disk so I decided to see if it would actually work. The process is actually fairly simple: take apart a floppy disk, cut out enough of the disk (the Mylar and iron oxide recording medium) to cover camera lens, tape the piece of floppy disk over the lens, point your camera, and shoot your picture.

I actually did have an old floppy disk that I could use for this experiment:

Alzheimer’s disease is a debilitating neurodegenerative disease and the most common form of dementia. Symptoms include irritability, confusion, mood swings, language difficulties and memory loss. Cognitive dysfunction becomes more pronounced as the disease progresses, leading to the loss of bodily functions and eventually death.

California State Sen. Noreen Evans wants any food that contains a genetically modified ingredient to have a special label declaring it - unless the product is alcohol.

The British government is putting pressure on commissioners, and in turn general practitioners, to make more diagnoses of dementia and that is leading to concern in a BMJ editorial.

As long as mandates and subsidies continue, wind turbines will continue to be part of the alternative energy mix. 

That means going beyond hype and potential and focusing on physical design, such as spacing and orienting individual turbines to maximize their efficiency and minimize any "wake effects," where the swooping blades of one reduces the energy in the wind available for the following turbine. 

Five environmental groups are alleging that NASA could be about to break the commitments it made in a 2010 agreement to clean up all the detectable contamination at its former Santa Susana Field Lab (SSFL) rocket testing site in the Simi Hills of California.

They claim that NASA may be laying the groundwork for a breach by falsely claiming that commenters on its draft Environmental Impact Study (EIS) on the cleanup were evenly divided on whether NASA should live up to its obligations in the cleanup agreements. When pressed by environmental groups to provide actual data to backup such a claim, they say NASA refused, and one of the groups, Consumer Watchdog, submitted a Freedom of Information Act request, obtaining all submitted comments.
