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.

It is difficult for pharmaceutical companies to have good public relations in an immediate news and social media world - no matter how many trials are done, people can still have adverse effects or even suffer real harm - and social media detractors can just claim they are corrupt and convince a large segment of their followers. 

To make sure the public has as much confidence as possible in new products, all drugs have to undergo exhaustive, time-consuming and expensive testing. When high-profile media events like ebola, which killed 1/13,000th as many Americans this week as heart disease did, happen, there are calls to throw ethics and testing protocols out the window.
