6,500 year old hunting trophy found in eastern Croatia
Archaeologists in Bapska, eastern Croatia have stumbled across 6,500 year old deer antlers. The hunting trophy was found hanging on the wall of prehistoric house along with valuable items of jewellery, writes website dalje.com.
"We have the oldest deer hunting trophy in Croatia," said Marcel Buric, the head researcher at the Department of Prehistoric Archaeology of the Faculty of Philosophy in Zagreb. |  |
Big horned rhinoceros beetles are healthiest
The size of a male rhinoceros beetle's horn is a genuine indicator of its health, according to researchers.
The horns vary in size from small bumps to two-thirds of the insect's body length and are used in fights. Investigating the variation, US scientists found cells in the horn are more sensitive to "nutrition signals" than cells in other parts of the body. They suggest their findings could explain the evolution of super-sized body parts in the natural world. |  |
Largest ever Cherenkov telescope sees first light
On 26 July 2012, the H.E.S.S. II telescope started operation in Namibia. Dedicated to observing the most violent and extreme phenomena of the Universe in very high energy gamma-rays, H.E.S.S. II is the largest Cherenkov telescope ever built, with its 28-meter-sized mirror. Together with the four smaller (12 meter) telescopes already in operation since 2004, the H.E.S.S. (“High Energy Stereoscopic System”) observatory will continue to define the forefront of ground-based gamma ray astronomy and will allow deeper understanding of known high-energy cosmic sources such as supermassive black holes, pulsars and supernovae, and the search for new classes of high-energy cosmic sources.

Researchers link Martian surface "oddities" with subsurface water and impact craters
Investigating extremely detailed images of Mars produced by the High Resolution Imaging Science Experiment (HiRISE) camera – the largest ever carried on a deep space mission – researchers from Western University have discovered further evidence linking subsurface volatiles, such as water or ice, to previously recognized (but thought to be rare) pits, which commonly arise on the floors of Martian impact craters.
Livio Tornabene, an adjunct research professor in Western's Department of Earth Sciences and an investigator at the Centre for Planetary Science and Exploration, says deciphering the origin of these pits assists planetary geologists like he and CPSX Acting Director Gordon Osinski in understanding how impact craters affect the hydrological and climatic history of Mars. |  |
Enceladus: home of alien lifeforms?
Enceladus is little bigger than a lump of rock and has appeared, until recently, as a mere pinprick of light in astronomers' telescopes. Yet Saturn's tiny moon has suddenly become a major attraction for scientists. Many now believe it offers the best hope we have of discovering life on another world inside our solar system.
The idea that a moon a mere 310 miles in diameter, orbiting in deep, cold space, 1bn miles from the sun, could provide a home for alien lifeforms may seem extraordinary. Nevertheless, a growing number of researchers consider this is a real prospect and argue that Enceladus should be rated a top priority for future space missions. |  |
Could there be life on five newly discovered planets?
Is life on other planets possible? Well a team of American astronomers certainly seem to think so.
Five new planets were discovered by NASA's Kepler Space Telescope earlier this year and even though they're 10,000 light-years away from us, we have a lot in common. They rotate round their star in a similar way to Earth as it goes round the Sun. So scientists at the Arecibo Observatory in America studied the planets to see if they have the right geography, temperature and amount of gravity for livings things to exist there. |  |
