Fatty Foods Vs. The Blues

A great number of people instinctually reach for the ice cream or chocolate during times of stress, and this phenomenon has been widely attributed to the sweet tooth. However, a recent study has shown that there is more to it.

Fatty foods do grant the consumer a degree of comfort, but not only because they are pleasurable to eat. The digestive system actually sends signals to the brain while digesting these foods, according to research conducted by scientists at the University of Leuven in Belgium.

Published in the Journal of Clinical Investigation, the study used MRI scans to map the effects of fatty acids on emotions when they are injected directly into the stomach.

12 volunteers were exposed to sad music and images before receiving fluid through a feeding tube. Some received a dose of fatty acids, and others; a saline solution.

The participants then rated their moods, without discovering which substance they had digested.

Those given fatty acids proved to be 50% less sad than those who received the saline solution, despite the sad atmosphere.

Lukas van Oudenhove, the scientist who led the research, said “Eating fat seems to make us less vulnerable to sad emotions, even if we don’t know we’re eating fat. We bypassed sensory stimulation by infusing fatty acids directly into the stomach, without the subjects knowing whether they were getting fat or saline.”

The study may have an impact on the studies of obesity, eating disorders and depression.

Tool to Track Photo-Taking

In America, spies are currently working on the development of a tool that will enable computers to identify where a photo was taken.  The project is being run by the Intelligence Advanced Research Projects Agency (IAPRA).  According to an article in The Daily Mail, the reason for this tool is mainly for the military to have the capacity to “track down terrorists who are in hiding in remote regions.”

The way it will work is by scanning photos of the targets into a computer that will be able to speedily return “an exact match for the terrorist hideout.”  Thereafter troops will be sent to that area to capture the target.

Changing Terrorist Targeting

If this works and goes ahead, it could actually “revolutionize” terrorist targeting by various intelligence agencies.  The photos and tapes will be gleaned from Al Qaeda, Taliban and other such terrorist organizations.  The filming often originates in “remote caves or barren hillsides in the depths of the Middle East.”

Bin Laden Capture

One example given of how effective and helpful the tool will be, is the Bin Laden case.  According to the scientists behind this development, had this tool been available years ago, his capture may have happened much earlier.  Without the tool, the situation is as follows:  intelligence analysts are forced to find the place where a photo was taken through a grueling analysis of its every detail.

Potential Problems

Currently, it is not known how this tool will actually work.  What might be problematic is the fact that currently the computer may have too many images in its database which will lengthen the process of finding the match.  However, if this tool advances further, then it will be able to “deduce the air pressure from the photograph and link it to a region with similar conditions at the time the photograph was taken.”  But we shouldn’t jump the gun as even the IARPA is realistic in its knowledge that something like this is unlikely to be available until 2016.
