New Natural Material Even Stronger Than Spider Silk

Many of us have been fascinated by the strength of Spider webs as it has thought as the strongest natural material on the Earth. Spider silk has a tensile strength same as that of a high-grade steel alloy and strongest than most of the metals and alloys with only the density of one-sixths of the steel.
While now scientist has discovered a new 'strongest natural materials' which is the teeth of Limpet, a type marine animal.
Asa Barber, from the School of Engineering at Portsmouth University in the UK, said " Until now, we thought that spider silk was the strongest biological material because of its super-strength and potential applications in everything from bullet-proof vests to computer electronics. But now we have discovered that limpet teeth exhibit a strength that is potentially higher'.
While examining teeth of the Limpet to the atomic structure, the team found a super-hard, iron-bearing hydroxide mineral called goethite in the tooth structures. Researchers are trying to copy the structure and synthetically manufacture it to be used in cars, planes etc. It will used in engineering applications like Formula One car etc.

Goodbye, Oppurtunity. Nasa mars rover 'Opportunity' no longer resposding.

Opportunity, the intrepid NASA rover that spent 15 years on Mars climbing in and out of craters to gather evidence of the planet's watery past, has been brought down by tiny particles of dust. After weeks of trying to revive the veteran Mars rover in the wake of a blinding dust storm, NASA has given up on ever hearing from it again. It's a humble ending for a machine that survived a 300-million-mile journey through space, executed a hole-in-one landing, and set a record by driving more than 28 extraterrestrial miles. Opportunity's last transmission to Earth occurred on June 10 amid an epic Martian dust storm. Still, NASA engineers remained hopeful that when the dust settled, the rover would recharge its solar-powered batteries and resume its superlative mission. Opportunity landed on Mars in January 2004 for a mission that was supposed to last 90 Martian days. Its twin rover, Spirit, had landed three weeks earlier on the other side of the planet. "Wit

Telescopic Contact Lens For Visually Impaired People

See far distance just by winking your eyes. A team of engineers have designed a telescopic contact lens that can switch between normal and magnefied vision. The Researchers at San Jose, California has built a prototype pf lens that could one day help people with visual impairment to see. The lenses might be particularly useful with age-related macular degeneration, a debilitating condition in which people gradually lose their central vision. It is the leading cause of visual impairment and affect millions worldwide. The contact lens developed by Ford’s team is one millimeter thick. Researchers used aluminum mirrors, fit tightly together, to create a ring-shaped telescope embedded in the contact lens. The center of the lens allows for normal, non-magnified vision. Its periphery, where the telescope is located, magnifies images 2.8 times. Switching between normal and magnefied vision Without the glasses, the contact lenses superimpose both normal and magnified images. With

A new future weightless Insulation material

A totally new insulation material has been developed that is totally weightless but can still withstand high temperature, that would not be tolerated by other materials and destroy it. The porous aerogel is at least 99 percent open space , with the rest made up of an atomically thin ceramic called hexagonal boron nitride. The design proves extremely durable under high temperatures and rapid temperature shifts of over 1,000 degrees Celsius. “It’s notoriously hard to make materials that are not just lightweight, but can also be heavily heat resistant,” says Deep Jariwala, an engineer at the University of Pennsylvania. The new ultralight insulator may be especially well suited to shielding components on spacecraft , which must endure extreme temperature swings when turning toward or away from the sun or re-entering Earth’s atmosphere, he says. The aerogel comprises a network of tiny air pockets, with each pocket separated by two atomically thin layers of hexagonal b
