Teens develop condom for safe sex!

A team of teenage inventors have revealed a condom capable of changing colour when it comes into contact with STIs (sexually transmitted infections). The prescient prophylactic has a built-in indicator that alters its colour depending on what infection it picks up. It was revealed at the TeenTech Awards in London where it won the health category .Called the S.T.EYE, the project was the creation of Daanyaal Ali, 14, Muaz Nawaz, 13 and Chirag Shah, 14. “We created the S.T.EYE as a new way for STI detection to help the future of the next generation,“ said Daanyaal Ali from Isaan Newton Academy in Illford.“We wanted to make something that make detecting harmful STIs safer than ever before, so that people can take immediate action in the privacy of their own homes without the invasive procedures at the doctors.“
The molecules in the condom respond to the bacteria present in an infection and change color to indicate the presence of a given STD --green for chlamydia, yellow for herpes and blue for syphilis.
The S.T.EYE was only one of the projects on display at the TeenTech awards, which showcases the inventions of students using science and technology to solve real problems in a range of different categories. “We encourage students to take their ideas out of the classroom by putting them face-toface with industry professionals, helping to open their eyes to the real potential of their ideas,“ said TeenTech's founder and CEO, Maggie Philbin.
Other inventions on show at the awards included shoes that use the energy of walking to charge devices while on the go and wi-fi hair accessories that match the colour of clothing.Another invention called the eWaterTap is a device to be used in rural Africa to help communities manage their water systems.

Meteor Shower for your family celebrations!

Fancy a meteor shower racing across the night sky to mark your birthday? One
Japanese start-up is hoping to deliver shooting stars on demand and choreograph the cosmos.
And, say scientists, it's not just about painting huge pictures on the night-sky that would be visible to millions of people; artificial meteors could help us to understand a lot more about Earth's atmosphere.
Lena Okajima, who holds a doctorate in astronomy, says her company -ALE -is intending to launch a micro satellite that can eject shooting stars at exactly the right time and place to put on a celestial show.
“I'm thinking of streams of meteors that are rare in nature,“ Okajima said.
“It is artificial but I want to make really beautiful ones that can impress viewers,“ she said.
In collaboration with scientists and engineers at Japanese universities, the ALE team is developing a satellite that will orbit the Earth and eject dozens of balls, a few centimetres in diameter, at a time.
These balls -whose chemical formula is a closely-guarded secret -will race through the atmosphere at around 7-8 kilometres a second, glowing brightly from the friction created by smashing into the air.
Although it sounds fast, that is considerably slower than naturally-occurring meteors, which can hurtle through the atmosphere at up to 80 kilometres a second.
Tinkering with the ingredients should mean that it is possible to change the colour of each bright streak, says Okajima, offering the possibility of a multi-coloured flotilla of shooting stars.

Flying with chickens!

As the world's consumption of meat increases, so does another problem - the excrement of factory farm creatures. Now, however, chicken giant Perdue has teamed up with two energy companies to build a $200 million plant in Maryland that will convert the excess chicken excrement into energy. The idea is that the poop will go through an anaerobic digestion process, devoured by microbes that will produce methane, which can be used to generate electricity. Now even your electricity can taste like chicken.
