South African scientists will share the country's latest fossil discovery with the world using live virtual technology.

Scientists from the Wits Institute for Human Evolution based at the University of the Witwatersrand in Johannesburg will announce the discovery of a large rock containing significant parts of a skeleton of an early human ancestor on Friday, 13 July 2012. The skeleton is believed to be the remains of 'Karabo', the type skeleton of Australopithecus sediba, discovered at the Malapa Site in the Cradle of Humankind in 2009.

Professor Lee Berger, a Reader in Palaeoanthropology and the Public Understanding of Science at the Wits Institute for Human Evolution, will make the announcement at the Shanghai Science and Technology Museum in Shanghai, China on Friday, 13 July 2012 at 09:00 South African standard time. Prof Berger is visiting China as part of a South African delegation promoting trade, business and tourism relations between the two competitive city regions, Gauteng and Shanghai.

New discovery

"We have discovered parts of a jaw and critical aspects of the body including what appear to be a complete femur (thigh bone), ribs, vertebrae and other important limb elements, some never before seen in such completeness in the human fossil record," says Berger. "This discovery will almost certainly make Karabo the most complete early human ancestor skeleton ever discovered. We are obviously quite excited as it appears that we now have some of the most critical and complete remains of the skeleton, albeit encased in solid rock. It's a big day for us as a team and for our field as a whole."

The remains are invisible to the casual observer and are entrenched in a large rock about one metre in diameter. It was discovered almost three years ago, but lay unnoticed in the Wits laboratories until early last month. Prof. Berger and his wife Jackie Smilg, a radiologist at the Charlotte Maxeke Hospital, who is conducting her PhD on the CT scanning of fossil material embedded in rock, scanned the large rock in a state of the art CT scanner.

A world first – Live Science!

In an unprecedented gesture of open access to science and public participation, the University of the Witwatersrand, the Gauteng Provincial Government and the South African national government announced that for the first time in history, the process of exploring and uncovering these fossil remains would be conducted live, captured on video, and conveyed to the world in real time. This will allow members of the public and the scientific community to share in the unfolding discovery in an unprecedented way.

A laboratory studio, designed in collaboration with the National Geographic Society, will be built at the Maropeng Visitor Centre in the heart of the Cradle of Humankind World Heritage Site. It will allow the public to view the preparation of this skeleton live if they visit Maropeng, or live on the internet. "The public will be able to participate fully in Live Science and future discoveries as they occur in real time – an unprecedented moment in palaeoanthropology," explains Berger. "The laboratory studio will be also linked to laboratories at Wits University and the Malapa site."

National Geographic

"We are excited to have helped make this cutting-edge facility possible for the University of the Witwatersrand," says National Geographic Executive Vice President Terry Garcia. "We can't wait to watch palaeontology happening in real time."

Virtual outposts

Access to the laboratory studio will not be limited only to visitors to the Cradle of Humankind and the internet. "We intend to create virtual 'outposts' in major partner museums around the world," says Berger. "These outposts will allow visitors to these partner museums the chance to interact with scientists in real time in a way we simply could not conceive of a few years ago. It is anticipated that the laboratory and virtual infrastructure will be built within a year, expanding our ambitious tourism and smart province infrastructure programme."

Berger adds that negotiations have begun with the Shanghai Science and Technology Museum, the Natural History Museum in the United Kingdom and the Smithsonian in Washington. "We have already donated casts of Australopithecus sediba to these three institutions, amongst others," says Berger. "It has also just been confirmed that one of the virtual outposts will be hosted in the new Shanghai Natural History Museum due to open later this year."

University of Utah physicists invent 'spintronic' LED

2012-07-13
SALT LAKE CITY, July 12, 2012 – University of Utah physicists invented a new "spintronic" organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television and computer displays, lighting, traffic lights and numerous electronic devices. "It's a completely different technology," says Z. Valy Vardeny, University of Utah distinguished professor of physics and senior author of a study of the new OLEDs in the July 13, 2012 issue of the journal Science. "These new organic LEDs can be brighter ...

Paisley Caves yield 13,000-year old Western Stemmed points, more human DNA

2012-07-13
EUGENE, Ore. -- (July 12, 2012) -- Archaeological work in Oregon's Paisley Caves has found evidence that Western Stemmed projectile points -- darts or thrusting spearheads -- were present at least 13,200 calendar years ago during or before the Clovis culture in western North America. In a paper in the July 13 issue of Science, researchers from 13 institutions lay out their findings, which also include substantial new documentation, including "blind-test analysis" by independent labs, that confirms the human DNA pulled earlier from human coprolites (dried feces) and reported ...

Male sex ornaments are fishing lures, literally

2012-07-13
Talk about a bait-and-switch. Male representatives of the tropical fish known as swordtail characins have flag-like sex ornaments that catch mates just like the bait on a fishing rod would. What's more, a study reported online on July 12 in Current Biology, a Cell Press publication, shows just what any good fly-fisherman would know: Lures work best if they mimic the foods that fish most often eat. For some characins in the study, that means males are waving pretend ants around in hopes of getting a bite. "This is a natural example of a fishing lure designed to maximize ...

Sake, soy sauce, and the taming of the microbes

2012-07-13
We all know that humans have domesticated plants and animals for our sustenance and enjoyment, but we've tamed various microbes as well. Now researchers reporting online on July 12 in Current Biology, a Cell Press publication, show that the mark of that domestication on microbes, and specifically on the mold used for thousands of years to brew sake and soy sauce from rice and soybeans, looks rather unique. While changes brought by domestication to plants and animals have rested largely on exaggerating physical traits, changes to microbes have occurred instead via extensive ...

In adult humans, brown fat is actually beige

2012-07-13
The calorie-burning and heat-generating brown fat found in full-grown humans is actually not quite brown; it's beige. So says a new study reported on July 12th in the journal Cell, a Cell Press publication, in which researchers fully characterize this promising obesity-fighting tissue in both mice and humans for the first time. The findings could lead to more specific ways to address the epidemic of obesity and diabetes by giving those beige fat cells a boost, the researchers say. "We've identified a third type of fat cell," said Bruce Spiegelman of Harvard Medical ...

The challenges facing the vulnerable Antarctic

2012-07-13
A century ago, the South Pole was one of Earth's last frontiers, but now the Antarctic is under threat from human activity. Led by Monash University's Professor Steven Chown, a multidisciplinary team of experts from around the globe has set out the current and future conservation challenges facing the Antarctic in a Policy Forum article published today in Science. The team analysed the effectiveness of the existing Antarctic Treaty System for protecting the region, one of the world's largest commons, from the threats of climate change and, as technology improves, increasing ...

Solar system ice: Source of Earth's water

2012-07-13
Washington, DC —Scientists have long believed that comets and, or a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth's volatile elements—which include hydrogen, nitrogen, and carbon—and possibly organic material, too. Understanding where these volatiles came from is crucial for determining the origins of both water and life on the planet. New research led by Carnegie's Conel Alexander focuses on frozen water that was distributed throughout much of the early Solar System, but probably not in the materials that aggregated to ...

Oregon's Paisley Caves as old as Clovis sites -- but not Clovis

2012-07-13
CORVALLIS, Ore. – A new study of Oregon's Paisley Caves confirms that humans used the site as early as 12,450 radiocarbon years ago, and the projectile points they left behind were of the "Western Stemmed" tradition and not Clovis – which suggests parallel technological development of early inhabitants to the Americas. The study, published this week in the journal Science, could have a major impact on theories of how the Western Hemisphere was populated. The research was funded by multiple organizations, including the National Science Foundation. Lead author Dennis ...

Dana-Farber study shows newly isolated 'beige fat' cells could help fight obesity

2012-07-13
BOSTON—Scientists at Dana-Farber Cancer Institute have isolated a new type of energy-burning fat cell in adult humans which they say may have therapeutic potential for treating obesity. Called "beige fat," the cells are found in scattered pea-sized deposits beneath the skin near the collarbone and along the spine in adult humans. Because this type of fat can burn off calories – rather than store them, as "white fat" cells do – beige fat cells might spawn new therapies for obesity and diabetes, according to researchers led by Bruce Spiegelman, PhD, of Dana-Farber. Spiegelman ...

Discovery opens door to attacking biofilms that cause chronic infections

2012-07-13
A clever new imaging technique discovered at the University of California, Berkeley, reveals a possible plan of attack for many bacterial diseases, such as cholera, lung infections in cystic fibrosis patients and even chronic sinusitis, that form biofilms that make them resistant to antibiotics. By devising a new fluorescent labeling strategy and employing super-resolution light microscopy, the researchers were able to examine the structure of sticky plaques called bacterial biofilms that make these infections so tenacious. They also identified genetic targets for potential ...
