Sprinting for 60 minutes a week burns as much fat as jogging for 7 hours a week! 

Switching up your speed while exercising can help burn more fat--perhaps more drastically than we ever realized. According to a study of 40 overweight males who did speed training over 12 weeks, this training can cause a significant drop in body fat and an increase in muscle mass.

The scientists were trying to find the minimum amount of exercise you could do with the largest health factors. They had the men exercise three times a week, and these exercises included periods of sprinting. They lost an average of 2 kilograms of body fat. Other studies have shown that men would need to jog for five to seven hours a week for about 3 months to lose the same amount of fat.

The men worked out for three 20 minute sessions each week, and during each session were sprinting for about 8 minutes. The lost mostly visceral fat, which is linked to cardiovascular disease risk.

The washing machine looks normal: you load clothes, let the machine do the work, and then take them out to dry. However, instead of using water, tiny nylon beads suck up stains. It takes loads up to 44 pounds per cycle (that is a lot of laundry...) and gets rid of stains from mud to red wine to ballpoint pens. 

Xeros explains how the beads work:

"The nylon polymer has an inherent polarity that attracts stains. Think of how your white nylon garments can get dingy over time as dirt builds up on the surface despite constant washing. However, under humid conditions, the polymer changes and becomes absorbent. Dirt is not just attracted to the surface, it is absorbed into the centre. This is exactly what happens when Xeros nylon beads are gently tumbled with dampened garments."

Google has been secretly creating and testing a car that can drive itself automatically through artificial-intelligence software, as well as computer hardware resting in the trunk.

This car even has a personality of its own, such as "cautious" or "aggressive," to fit driving conditions.

Says Google, "Our automated cars use video cameras, radar sensors and a laser range finder to “see” other traffic, as well as detailed maps (which we collect using manually driven vehicles) to navigate the road ahead. This is all made possible by Google’s data centers, which can process the enormous amounts of information gathered by our cars when mapping their terrain."
