An endangered giant African bat has been spotted again in swelled numbers by conservationists who think it may have emerged from near extinction.

Under the constant watch of environmental conservation groups for more than two decades, the fruit bat with a wing span of almost 6 feet wide has faced numerous odds to recover its numbers which now stand at a remarkable 22,000, according to a newly released research finding.

Archaeologists in China have discovered the fossilized remains of a feathered dinosaur the size of a pigeon believed to have lived millions of years before birds evolved but which may be an early avian ancestor.

The discovery of a 90% intact fossil preserved in a slab of rock at a site in Laioning Province in Inner Mongolia, heightens the notion that tiny-bodied, carnivorous bipedal dinosaurs are closely related to and most certainly evolved into birds.

Peruvian and Brazilian authorities are trading accusations that uncontrolled logging on the Peruvian side of the Amazon Forest is uprooting isolated Indian tribesmen forcing them to flee across the border into Brazil in search of untampered land and food.

Indigenous rights groups and Indian tribes researchers in Brazil now believe the uprooting may be a recipe for renewed inter-tribal conflicts over the resource that may suck governments of both nations into a row over the other’s responsibility in the affair, Reuters reports.

Scientists have discovered a hybrid plastic-metal material that generates electrons in a way that can easily be captured on a spectrum and at the same time efficiently absorb all the energy from a ray of sunlight.

The material is a computerized lab creation that combines electrically conductive plastic with several metals including molybdenum and titanium. It overcomes the two major roadblocks involved in capturing solar energy: taking in all energy from sunlight and producing easily-capturable electons. Thus, the new material may have the potential to revolutionize how manufactured solar cells obtain energy from the sun.

Researchers in Germany are trying to understand the connection between weather conditions and human emotion.
Stress is part of day-to-day life and we can attribute it to lots of things, including the weather. If you feel irritable or stressed for missing your daily walk on a rainy afternoon when it’s just supposed to be cool, you are probably very right in blaming the weather. However, a new study suggests that as a rule of thumb the weather really might give us more to grumble about than to be happy about.

A research team at Humboldt University in Berlin, Germany claim in a study published in the October issue of the Emotions journal that temperature, wind, and sunlight all have an effect on negative moods, with sunlight seemingly playing a significant role on how tired people said they were.

On the other hand, temperature, wind, sunlight, precipitation, air pressure, and how long the days were had no significant effect on positive moods, contrary to conventional wisdom.

An intelligent LED street lighting system that stays dim when humans are not around but increases its luminosity when it senses people walking nearby has been unveiled.

Philips, promotes the innovative street lighting concept as an ecological street light pole. The pole adapts its shape to capture the maximum source energy from sun and wind during daytime, using this energy during the night for illumination.

Depending on weather conditions, it can alternate between solar and wind modes.

Employing ‘flower mechanics’, the Light Blossom opens its petals to collect solar energy on sunny days and reorients them upwards to harness wind energy on cloudy days which, in turn, powers the lighting pole at night.

In drought-stricken Kenya, male goats are forced to fire blanks by wearing a condom that will prevent them from breeding to save on scant resources.

Made from cowhide or anything from braided grass to discarded wood pieces or old sandals, the condom is not a sheath but a home made contraption that is designed to get in between the buck’s belly and the doe’s genitalia thus preventing mating.

In the absence of modern breeding methods in remote districts of Kenya mainly inhabited by Maasai herdsmen, the traditional condom, or olor in the local language, is secured under the belly with a rope or elastic strap.

“Sometimes it falls upon a generation to be great. You can be that generation” - Nelson Mandela, Make Poverty History rally, Trafalgar Square, London, UK, February 2005

What makes a political leader to be great? What makes a generation to be great? To think of it, one word defines it - sustainability. Would this, then, be a moral issue or an economic issue?

Does the world’s population today — both older and younger segments — understand the social dilemma that the next generation of leaders just on the threshold of global influence find themselves in?

Yes, next generation of leaders. Because we can no longer hedge our hopes and beliefs and inspirations on leaders who are stuck in the time warp of old politics.

‘Intelligent’ elephants in Africa are getting tech-savvy and are using cellphone text messages to report their own encroachment on farms in a novel experiment local conservationists believe will help avoid human-wildlife conflict.
Rangers at a wildlife conservancy in Kenya are getting accustomed to blips on their phones each time an elephant attempts to cross a virtual ‘fence’ that triggers an automatic text signal using Google Earth software.

AP reports that SIM cards on elephants’ global positioning system (GPS) collars beam messages to rangers on duty whenever they approach the “geo-fence” that mirrors the 90,000 acre Ol Pejeta Conservatory’s boundaries. The rangers then use spotlights to frighten the elephants back inside the protected area.

Scientists have uncovered life in a South African gold mine, 2.8 kilometers (1.7 miles) beneath the surface of the earth. In this dark but hot ecosystem, a single biological species derives power not from the sun but from elements produced by uranium’s radioactive decay.
Remarkably, it is the first ecosystem ever found having only one biological species. In utter darkness, total isolation, with no oxygen, and in 60-degree-Celsius heat (140 degrees Fahrenheit), the cave-dwelling, rod-shaped bacterium, Desulforudis audaxviator survives.

Trajectories of evolution have fitted the bacterium with the genes necessary to exist under a variety of different conditions. One such adaptation is the ability to survive by fixing nitrogen and carbon directly from the environment.
