Zebra Stripes as Bug Repellant

David A Gabel, ENN — Thu, 09 Feb 2012 09:46:00 EST

On the plains of Africa, the zebra are not the only creature roaming in herds. There are a great number of other species, not least of all, the dreaded horsefly. Zebras, like all horse species, have large bodies which they cannot always reach with their mouths, hooves, or tails, making them an inviting prey for blood-sucking, flying insects. More than the lion, the horsefly is the bane of zebra's existence. This, according to a recent study published in the Journal of Experimental Biology, is why zebras evolved to having stripes. The black and white stripes effectively deter the horseflies by making the zebras less attractive.

Cambridge University reveals breakthrough for super-efficient solar cells

New solar cells could increase the maximum efficiency of solar panels by over 25%, according to scientists from the University of Cambridge. Scientists from the Cavendish Laboratory, the University's Department of Physics, have developed a novel type of solar cell which could harvest energy from the sun much more efficiently than traditional designs. The research, published today, could dramatically improve the amount of useful energy created by solar panels.

German-Saudi Partnership to Build Polysilicon Plant in Red Sea City

Germany's Centrotherm Photovoltaics, the world's second-largest manufacturer of solar photovoltaic (PV) equipment, has signed an agreement with IDEA Polysilicon to construct a polysilicon solar PV manufacturing facility in the Saudi Arabian Red Coast city of Yanbu, according to a Reuters News report. The agreement aims to provide IDEA the technology and know-how it needs to become a market force in the Middle East-North Africa (MENA) region, a market that's attracting more and more interest from industry players globally.

Hertz First To Trial Wireless EV Recharging

Editor — Thu, 09 Feb 2012 06:17:00 EST

The Hertz Corporation and Hertz Global EV are implementing the first wireless charging system for electric vehicles (EVs) in the car rental industry. Hertz has the most diverse fleet of EVs for both rental and carshare. "Hertz is committed to its Global EV program, introducing electric vehicles into our rental fleet on three continents – North America, Asia and Europe," commented Mark P. Frissora, Hertz Chairman and Chief Executive Officer. "We're excited to participate in Plugless Power’s pilot program so that we can be on the ground floor of this new technology; learning key findings about EV wireless charging. As we move forward our goal is to have a variety of charging options for EV customer use, aligned with the charging equipment installed by EV manufacturers."

Scotland releases blueprint for offshore renewable energy roll-out

A blueprint to streamline the scoping, planning and consenting of offshore renewables developments has been published by the Scottish Government today. The report, prepared by a task force comprising Marine Scotland, environmental regulators, renewable developers and The Crown Estate, was welcomed by Alex Salmond as he co-chaired the first 2012 meeting of the Scottish Energy Advisory Board (SEAB).

Tree Rings and Volcanic Eruptions

Counting the number of tree rings and observing the relative growth for each ting can give an age for when something happened. However, it may not be that simple. Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change, because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers who compared tree-ring temperature reconstructions with model simulations of past temperature changes.

Housecats Susceptible to Wild Feline Disease

There are really two types of cats out there: the cute and cuddly house cat and the vicious predator wildcats. However, for bacteria and viruses, there is no difference. The domestic cats are equally vulnerable to the same diseases that afflict wild bobcats, cougars, and others. A new study led by Colorado State University found that all cats living in the same area share the same diseases. In fact, domestic cats can act as a bridge to spread feline diseases to human households.
