Starpath is a cement and tarmac coating agent that uses light from the sun during the day to glow along pathways at night!


It is costly to keep pathways in parks well lit to ensure the safety of cyclists and pedestrians, but Pro-Teq (a British based company) has developed a product that can drastically cut back on those costs. 'Starpath' is a spray-on coating of light-absorbing particles that harvests ultra-violet rays from the sun during the day and dramatically lights up at night.

It is anti-slip and waterproof and can be applied to various surfaced like cement, wood and tarmac. 'Starpath' comes with added benefits. Its non-reflective surface doesn't contribute to light pollution, which not only limits views of the night sky, but has negative consequences for local nocturnal wildlife due to the constant illumination.

"Our surface works best over tarmac or concrete, predominantly tarmac, which is the main bulk of the U.K. Path network," says Pro-Teq's Neil Blackmore. "When it's coming to the end of its useful life, we can rejuvenate it with our system, creating not only a practical, but a decorative finish."

It is, however, not yet determined whether 'Starpath' will be illuminating enough to also deter crime to the extent that overhead streetlights do. Neil Blackmore suggests that for larger urban parks where the possibility of crime is higher, his technology could be used in conjunction with overhead lighting, if not replacing street lights completely.

The top nine Apple executives made as much in 2011 as 95,000 Chinese workers making Apple products.


The executive leadership team of Apple (nine members in all) was compensated a total of $441 million in 2011. In contrast, it took a total of 95,000 Chinese factory workers at Apple's supplier, Foxconn, to earn an equivalent amount in wages. Those numbers vary slightly from year to year but are expected to be similar.

To accentuate the different worlds in which the workers and executives seem to live, the Fair Labor Association decided to do some investigation. 64% of the factory workers did not consider their salaries sufficient, despite working for an average of 56 hours per week and in questionable conditions. At the end of the year, the average Chinese factory worker earned $4,622.

All nine members of Apple's executive team made over $1 million each in 2011, but two of them made substantially more. Timothy Cook alone made $378 million, making him the highest paid of any CEO. In a distant second was Eduardo Cue, who made $53 million as senior vice president of the company. The vast majority of their earnings came in the form of restricted stock awards.

Note: The figures given are for the fiscal year of 2011, which doesn't correspond exactly to the calendar year.

This type of power plant releases more uranium into the air in one week than a nuclear plant does in 50 years!


Everybody is aware of the possible dangers, health risks to humans, and harm to the environment that nuclear power stations hold, but what are the risks of coal-fired power plants? Bernard L. Cohen, Professor-Emeritus of Physics and Astronomy and of Environmental and Occupational Health at the University of Pittsburgh, gives us an idea. Spoiler: It's not good.

Coal-fired power plants generate over half of the US' electrical power needs. The coal burnt in those plants generates approximately 274,000 tons of waste every day, which contains nearly every element known, including sulphur, chromium, mercury, lead, arsenic, and uranium!

Coal-burning power plants generate about 3.3 tons of uranium waste every single day in the US, and that gets released into the environment. On average, the amount of uranium coal plants discharge into the environment every week is much higher than the total amount of uranium released into the environment by the nuclear power industry over its entire 50-year history. That includes the disastrous accidental release at Three Mile Island and Chernobyl!

Professor Cohen feels that we have the technology to eliminate air, soil, and water pollution now, and he believes we need to put that technology to work now. He says that nuclear power can provide the electricity needed to end coal power pollution.

Some awesome lists!

Only talented coders can find Flickr's job posting for software engineers. Where is it hidden?


As you know, Flickr is one of the best-known brands on the internet with about 90 million users per month. They serve billions of pageviews and more than 7 billion API requests monthly for over 75 million registered photographers.

Many companies spend a lot of money on placing hundreds of ads for job vacancies in order to get the right candidate for a particular job.

Flickr, however, has found a way to cut down on ad costs and still ensure they get the right person for the job, saving their HR department from the daunting task of sifting through thousands of 'potentials.'

They advertise job openings for software engineers where only somebody worthy of the job will ever find it—inside the source code of the website!

If you find it, you will see it reads: "You're reading. We're hiring." That should cut down on a lot of paperwork and interviews.

Flickr is a part of Yahoo! And offers employees great benefits like multiple medical plans, breakfast, lunch and dinner, a smartphone, baby showers for new parents, and Yahoo! Gear for the kids. New parents also get a $500 daily habits allowance! When you start, you have 15 paid vacation days, plus 13 company holidays and—this may be the best of them all—unlimited sick days!

A laser is being developed in Europe that will have the power to rip apart the vacuum of space! So what are they going to do with it?


Plans are currently being drawn up for the Extreme Light Infrastructure (ELI). The goal for the ELI is to build the most powerful lasers ever to exist—over 10 times as powerful as any existing laser.

With current plans for lasers in Hungary, Romania, and the Czech Republic, the first stages of the project look to be completed in 2017. The group behind the ELI want to make these lasers available to the international scientific community to perform advanced physics experiments.

Their end goal involves developing a 200 petawatt laser that will have the power to pull apart the vacuum of space! This laser will be created by combining the beams of 10 smaller lasers—each more powerful that any currently in existence.

At energy levels as high as 200 petawatts, the usual laws of physics will start to break down, giving scientists a glimpse into the origins of our universe.
