Face detection algorithm about to revolutionize image search


Computer scientists Paul Viola and Michael Jones triggered a revolution in the field of computer face detection in 2001.  Their breakthrough was an algorithm that could spot faces in an image in real time, the so-called Viola-Jones algorithm was so fast and simple that it was soon built into standard point and shoot cameras.

New flexible 3D graphene supercapacitors

An electron microscope image shows the cross section of laser-induced graphene burned into both sides of a polyimide substrate.

By producing and testing stacked, three-dimensional supercapacitors — energy-storage devices that are important for portable, flexible electronics, Rice University scientists have advanced their recent development of laser-induced graphene (LIG). Continue reading… “New flexible 3D graphene supercapacitors”


Drilling May Be Behind Texas Earthquakes


Everything is bigger in Texas maybe even the earthquakes

The earth moved here on June 2. It was the first recorded earthquake in this Texas town’s 140-year history – but not the last.

There have been four small earthquakes since, none with a magnitude greater than 2.8. The most recent ones came Tuesday night, just as the City Council was meeting in an emergency session to discuss what to do about the ground moving.

The council’s solution was to hire a geology consultant to try to answer the question on everyone’s mind: Is natural gas drilling – which began in earnest here in 2001 and has brought great prosperity to Cleburne and other towns across North Texas – causing the quakes?

Fingerprint Grip Disproved By Science


Fingerprint theory rejected

Scientists say they have disproved the theory that fingerprints improve grip by increasing friction between people’s hands and the surface they are holding.

Nobody is sure of the exact function of fingerprints, but improved grip has long been a favoured theory.

However, in a series of tests to measure friction between a finger and a piece of acrylic glass, it was debunked by a University of Manchester team. Continue reading… “Fingerprint Grip Disproved By Science”


Brain Bots


Terminator like robots really could be on the horizon

Can we build a brain from the ground up, one neuron (or so) at a time? That’s the goal of neurobotics, a science that sits at the convergence of robotics, artificial intelligence, computer science, neuroscience, cognitive psychology, physiology, mathematics and several different engineering disciplines. Computationally demanding and requiring a long view and a macroscopic perspective (qualities not often found in our world of impatient specialization), the field is so Here Come the Neurobotsfundamentally challenging that there are only around five labs pursuing it worldwide. Continue reading… “Brain Bots”


Fire Up Your Hunger Hormone


If eating fatty foods was bad enough heres some more reasons to skip those fries

New research led by the University of Cincinnati (UC) suggests that the hunger hormone ghrelin is activated by fats from the foods we eat-not those made in the body-in order to optimize nutrient metabolism and promote the storage of body fat.

The findings, the study’s author says, turn the current model about ghrelin on its head and point to a novel stomach enzyme (GOAT) responsible for the ghrelin activation process that could be targeted in future treatments for metabolic diseases. Continue reading… “Fire Up Your Hunger Hormone”


Hunt n’ Peck Keyboard


Keyboarding for dummies

There are those who have never learned how to type. These people use a method called hunt n peck. Understandably, these people have a hard time trying to hunt and peck on a normal keyboard. With this keyboard, just hit the ABC key and it will switch to alphabetical order, making it easier to find the key you need. Continue reading… “Hunt n’ Peck Keyboard”


Time Lapse Videos Of Changes To The Earth


Earth changes seen threw the lens of a time lapse camera

Over the past decade, the number of people on Earth shot up by more than 13 percent, to nearly 6.8 billion people. To make room for all the hungry, breeding, CO2-emitting bodies on our small planet, we’ve ravaged Earth’s surface with staggering feats of deforestation, irrigation and urbanization – and NASA satellites have captured it all.
