Super broccoli can fight chronic diseases

Scientists have discovered that eating broccoli, packed with a health-boosting compound called ‘glucoraphanin’, helps maintain cellular processes that can cause deadly conditions like obesity and some cancers.

Researchers at the Institute of Food Research in Norwich created the super-strength variety called Beneforte in 2010.

However, after further research it was found that the vegetable works to fight major diseases by helping people’s metabolism work well, the Daily Express reported.
The study is published in the American Journal of Clinical Nutrition.

Woven silver strands pave way for flexible electronics

Scientists at the National Physical Laboratory (NPL), the UK’s National Measurement Institute, have developed a way to print silver directly onto fibres, which could pave way for flexible, wearable electronics.

This has many potential applications in sports, health, medicine, consumer electronics and fashion.

 Most current plans for wearable electronics require weaving conductive materials into fabrics, which offer limited flexibility and can only be achieved when integrated into the design of the clothing from the start.

NPL’s technique could allow lightweight circuits to be printed directly onto complete garments. Silver coated fibres created using this technique are flexible and stretchable, meaning circuits can be easily printed onto many different types of fabric, including wool which is knitted in tight loops.

The technique involves chemically bonding a nano-silver layer onto individual fibres to a thickness of 20 nm. The conductive silver layer fully encapsulates fibres and has good adhesion and excellent conductivity.

 “The technique has many potential applications. One particularly exciting area is wearable sensors and antennas which could be used for monitoring, for example checking on patients and vulnerable people; data capture and feedback for soldiers in the field; and performance monitoring in sports,” project leader Chris Hunt said.

US firm plans to slingshot objects into space

A company from Virginia is developing an alternative transportation system to send small payloads and bulk cargo, like water or fuel, into space.  Rather than chemical rockets, HyperV Technologies Corp., proposes to slingshot objects off the planet, Discovery News reported.

The company’s so-called “Slingatron” is using a spiral-shaped steel track that accelerates a payload with gyrating, hula hoop-like motions.

 HyperV president and chief scientist Doug Witherspoon said that at about 60 cycles per second and precision timing, a payload traveling along the inside of the spiral will synchronize with the hula hoop-motion and continue accelerating.  The firm last week launched a $250,000 fundraising initiative to build its third Slingaton prototype. The machine would have a five-meter diametre spiral track that theoretically could get a 1-pound payload moving along at 1 kilometre per second (0.62 miles per second.)
To get into low-earth orbit, such as where the International Space Station flies, an object needs to be moving at about 7.6 kilometres per second (4.7 miles per second.) For its demonstration run, HyperV intends to use a quarter-pound payload.
