Most people associate osteoporosis with women. But the truth is, one in four men over the age of 50 will break a bone as a result of this condition. That's more men than will have prostate cancer, according to the National Osteoporosis Foundation.

A true story. To protect the innocent – and the writer – I’ll use no names.

The president of a large, multi-national engineering and construction firm decided to attract more contracts by reducing customers’ risks. A sound decision, yes? 

It was what he did (which was to offer fixed-price contracts instead of cost-plus contracts) and how he did it (by developing his people and by continuous process improvement) that got him fired - even though the move was showing every sign of success.

So why was he dismissed? The answer lies in that ol’ stereotype of the corporation as an externality-generating machine.

Acoustics would seem to be primarily science - make sure sound waves are not piling up on each other in strange places and that everyone can hear what they are supposed to hear -  but a new study says it is not so objective and the response of audiences and performers to acoustic characteristics is a function of their worldview, according to archaeo-acoustician Steven J. Waller at the 169th meeting of the Acoustical Society of America in Pittsburgh.

"It's a parallel to 'beauty is in the eye of the beholder': perfect performance spaces are really in the ear of the listener. Today we value qualities like clarity--how it makes a modern orchestra sound," Waller continued, "whereas prior to sound wave theory, echoes were considered mysterious and divine."

Yesterday I posed a question - Are the first collisions recorded by the LHC running at 13 TeV the highest-energy ever produced by mankind with subatomic particles ? It was a tricky one, as usual, meant to think about the matter.

I received several tentative answer in the comments thread, and thus answered there. I paste the text here as it is of some interest to some of you and I wish it does not go overlooked.

Dear all, 

Fashion is a huge industry and they use thin models because creating an ideal - the belief that women will look like that if they buy the clothes - is a time-honored strategy.

Yet as more American women become overweight and obese, and it becomes more difficult to create suspension of disbelief about body imaging psychology, that old strategy is less effective. A survey of diverse group of 239 women finds that marketing to the "thin ideal" -- the belief that thinner is better -- could be alienating up to 70 percent of their audience, said James Roberts, Ph.D., The Ben H. Williams Professor of Marketing in Baylor's Hankamer School of Business.  

Advertisers tend to default to this ideal without knowing for sure if other options are viable, James Roberts said.

Mapping archaeological digs used to take plenty of time and a lot of measuring, photographing, drawing and note taking, much of which can now be done with a technique called photogrammetry.

Photogrammetry is a method that uses two-dimensional images of an archaeological find to construct a 3-D model and it doesn't require special glasses or advanced equipment. Coupled with precise measurements of the excavation, photogrammetry can create a complete detailed map of an archaeological excavation site while being more precise than older, more time-consuming methods.

This method is already being put to use by archaeologists. When a possible Viking grave was found in Skaun in Sør-Trøndelag in 2014, the excavation site was mapped using photogrammetry.

A study has found that individual differences in brain structure could help to determine the risk for future drug addiction. The study found that occasional users who subsequently increased their drug use compared with those who did not, showed brain structural differences when they started using drugs.

A new study led by investigators at Brigham and Women's Hospital (BWH) reports the discovery of a genetic variant that is associated with a patient's likelihood of responding to interferon-beta, one of the medications used in treating multiple sclerosis (MS). Published in the Annals of Neurology on May 14, the study also presents evidence that the affected gene, SLC9A9, may have a broader role in regulating the development and activity of certain immune cells that play important roles in inflammatory diseases like MS.

A proportion of MS patients experience disease activity despite treatment. The early identification of the most effective drug for a given individual is critical to impact long-term outcome and to move toward a personalized treatment approach.

It is somehow ingrained in my body, I think. The appreciation of biodiversity. I know I love wetlands, growing up by a lake (mostly in it as a child) as I did. It turns out that parts of that lake are so-called Ramsar wetlands of international importance. Little did I know, growing up to be an astrophysicist that these sites existed and that it would once become part of my professional life. Here. On my home planet.

A recent eye infection suffered by 18-year-old Nottingham University student Jess Greaney is the kind of story that fills us with horror.

Greaney had keratitis, an inflammation of the cornea, caused by Acanthamoeba castellanii, a parasite that was living and feasting on her eye.
