A new paper from the International Osteoporosis Foundation (IOF) says that one-third of all hip fractures worldwide occur in men, with mortality rates as high as 37% in the first year following fracture.

This makes men twice as likely as women to die after a hip fracture. Osteoporosis experts warn that as men often remain undiagnosed and untreated, millions are left vulnerable to early death and disability, irrespective of fracture type. 

When a sturdy material becomes soft and spongy, it's been damaged in some way. But when it comes to complex fluids and biological cells, things may be different.

By looking at the microscopic building blocks – known as "filaments" – of biopolymer networks, researchers from Forschungszentrum Jülich, Germany and the FOM Institute AMOLF in the Netherlands, revealed (Nature Communications DOI: 10.1038/ncomms5060)  that such materials soften by undergoing a transition from an entangled spaghetti of filaments to aligned layers of bow-shaped filaments that slide past each other. 

A little known secret in data mining is that simply feeding raw data into a data analysis algorithm is unlikely to produce meaningful results.

From recognizing speech to identifying unusual stars, new discoveries often begin with comparison of data streams to find connections and spot outliers. But most data comparison algorithms today have one major weakness – somewhere, they rely on a human expert to specify what aspects of the data are relevant for comparison, and what aspects aren't. But experts aren't keeping pace with the growing amounts and complexities of big data.

Decaffeinated coffee drinking may benefit liver health, according to a paper in Hepatology by  Researchers from the National Cancer Institute whichsayss that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes.

This suggests that chemical compounds in coffee other than caffeine may help protect the liver. 

Researchers are working to select autochthonous bacteria with biofertilizing potential as a result of the stimulating effect they have on the take-up of nutrients by plants, phytohormone production and phytopathogen control.

Both organic and synthetic fertilizers are expensive and not very sustainable from an environmental power of view so researchers from Neiker-Tecnalia, the Basque Institute for Agricultural Research and Development, in Spain, believe farmers would embrace bacteria-based biofertilizers.

Psychologists recently carried out hundreds of mock police lineups to determine the most successful procedure for identification of criminals. Inaccurate identification can obviously lead to the prosecution of innocent people while guilty ones go free.
