The Atlanta Falcons tested the retractable* roof on their new stadium which is due to host its fi rst exhibition game at the end of the month.

The Mercedes Benz Stadium, which cost an estimated US$1.6 billion, closed its roof for the fi rst time in advance of the new season. The revolutionary mechanism opens like the aperture* on a camera lens.

Once fully operation, the roof should be able to open or retract in just 15 minutes, protecting the 70,000 fans the elements.

However, despite the imminent* start of the

season, the roof will not be fully operational on day one. The project was hit by a number of delays which will impede* the operation of the

roof. While the roof might seem to rotate during its operation, this is an optical illusion. The eight petals are moved by giant mechanized

bogies which cantilever the structure into place. Once the roof is closed, air infl ated pillows are deployed to form a waterproof seal. The light-weight fabric is translucent* and allows light to pass through.

Contractors have begun the process of permanently attaching the mechanism to the roof structure, although it could be a number of months before the system is fully operational.

Work on attaching the mechanism will take longer than planned due to the stadium’s busy schedule. (SD-Agencies)

Shampoo strips hair of the natural oils and grease that help smells cling to strands. That means the pleasant odors of shampoo and con-ditioner tends to disappear within a few hours.

But researchers have developed technology that binds fragrances from sham-poo to the surface of hair so that the smell is gradually released.

Andreas Herrmann, a chemist at fragrance fi rm Firmenich, worked with the Swiss Federal Institute of Technology on the break-through.

The researchers pack-aged the fragrance inside capsules* that were many times smaller than the width of a human hair. Then, to get them to stick to hair, they studded the capsules with short fragments of protein.

The fragrance is released over 24 hours as the capsules burst gradually. Herrmann said the capsules do not change the way hair feels but further testing would be needed to ensure they do not affect combing or drying. (SD-Agencies)

German researchers have made sunglasses with col-ored, semitransparent* solar cells on the lenses that can recharge a phone.

The solar cells supply a microprocessor* and two displays with electric power, displaying the solar illumina-tion* intensity and ambient temperature and the glasses can even use some of the energy to power devices such as a phone.

The researchers say the technology could pave the way for other future applica-tions, such as the integration of organic solar cells into win-dows or overhead glazing.

Organic solar cells — which use energy from the sun to generate electricity — are unique in that they’re trans-parent and light-weight, and can be manufactured in dif-ferent shapes and colors.

They can be used for a wide range of applications that can’t be done with conventional* silicon* solar cells, which are heavier and more rigid.

The glasses, made by researchers at the Karlsruhe Institute of Technology, were designed as a case study demonstrating how organic solar cells can be used.

“We bring solar power to places where other solar technologies fail,” says Alex-ander Colsmann, head of Organic Photovoltaics Group at KIT’s Light Technology.

The smart Solar Glasses are self-powered to measure and display the degree of solar illumination and the temperature, and they also work in indoor environ-ments. (SD-Agencies)

Japanese scientists have come up with a cool solu-tion to stop ice cream from melting before you’ve had time to fi nish it.

The ice cream retains its original shape in 28°C weather and remains cool.

A strawberry extract stops the oil and water from separating so quickly which means the sweet treat stays frozen even if you blow a hair dryer at them.

Scientists at Japan’s Biotherapy Develop-ment Research Center in Kanazawa used a polyphe-

nol* strawberry extract to develop melt-resistant ice cream.

“Polyphenol liquid has properties to make it diffi -cult for water and oil to sep-arate,” said Tomihisa Ota, a professor at Kanazawa University.

“So an ice cream contain-ing it will be able to retain its original shape for a longer time than usual, and be harder to melt.”

The company created the non-melting ice cream by accident.

A pastry chef wanted to

create a new kind of con-fectionery* in order to use strawberries that were not the right shape to be sold. The initiative was part of efforts by the company to help strawberry farmers affected by the 2011 earth-quake and tsunami.

The chef realized that cream would solidify when put in contact with the straw-berry extract. Although this made the extract redundant in confectioneries, scientists realized it could be used to stop ice cream from melt-ing. (SD-Agencies)
