| Six natural wonders declared World Heritage Sites Posted: 02 Jul 2012 11:52 PM PDT Sangha Trinational -- shared between Cameroon, the Central African Republic and the Republic of Congo; Lakes of Ounianga in Chad and Chengjiang fossil site in China have been inscribed on the World Heritage List, following the recommendations of IUCN (International Union for Conservation of Nature). Lena Pillars Nature Park in Russia and Western Ghats in India were also added to the prestigious list by the World Heritage Committee. |
| Scientists create 'rubber-band electronics' Posted: 02 Jul 2012 06:02 PM PDT Scientists have developed a new way to make highly stretchable electronics. The technology could pave the way for bendable laptops and medical devices that can be integrated into the human body. |
| DNA sequenced for parrot's ability to parrot Posted: 02 Jul 2012 06:02 PM PDT Scientists say they have assembled more completely the string of genetic letters that could control how well parrots learn to imitate their owners and other sounds. |
| Posted: 02 Jul 2012 06:02 PM PDT A new species of feathered dinosaur discovered in southern Germany is further changing the perception of how predatory dinosaurs looked. The fossil of Sciurumimus albersdoerferi, which lived about 150 million years ago, provides the first evidence of feathered theropod dinosaurs that are not closely related to birds. |
| Posted: 02 Jul 2012 04:25 PM PDT "Getting under your skin" takes on new meaning thanks to research that could transform gene therapy. A team from the fields of dermatology and nanotechnology is the first to demonstrate the use of commercial moisturizers to deliver gene therapy with great potential for life-saving therapies for skin cancers. The drug -- consisting of novel spherical arrangements of nucleic acids -- penetrates the skin's layers and can selectively target disease-causing genes while sparing normal genes. |
| Day dreaming good for you? Reflection is critical for development and well-being Posted: 02 Jul 2012 03:40 PM PDT As each day passes, the pace of life seems to accelerate -- demands on productivity continue ever upward and there is hardly ever a moment when we aren't, in some way, in touch with our family, friends, or coworkers. While moments for reflection may be hard to come by, a new article suggests that the long-lost art of introspection --even daydreaming -- may be an increasingly valuable part of life. |
| Naked mole rat may hold the secret to long life Posted: 02 Jul 2012 01:23 PM PDT The naked mole rat's brain contains unusually high levels of NRG-1, a neuroprotecting protein, which preserves high activity, bone health, and cognitive ability throughout its lifespan, new research shows. And because the rodent has an 85 percent genetic similarity to humans, continuing investigation could lead to a longer and healthier life for us. |
| Natural intestinal flora strengthen immune system Posted: 02 Jul 2012 12:29 PM PDT Signals from natural intestinal bacteria are necessary for an effective immune response to various viral or bacterial germs, new research suggests. |
| Got kids? Then you're less likely to catch a cold Posted: 02 Jul 2012 12:26 PM PDT Being a parent reduces your risk of catching a cold—possibly because of unknown "psychological or behavioral differences between parents and nonparents," according to a new study. |
| Tevatron scientists announce their final results on the Higgs particle Posted: 02 Jul 2012 11:17 AM PDT After more than 10 years of gathering and analyzing data produced by the U.S. Department of Energy's Tevatron collider, scientists from the CDF and DZero collaborations have found their strongest indication to date for the long-sought Higgs particle. Squeezing the last bit of information out of 500 trillion collisions produced by the Tevatron for each experiment since March 2001, the final analysis of the data does not settle the question of whether the Higgs particle exists, but gets closer to an answer. |
| Mass extinctions reset the long-term pace of evolution Posted: 02 Jul 2012 10:48 AM PDT A new study indicates that mass extinctions affect the pace of evolution, not just in the immediate aftermath of catastrophe, but for millions of years to follow. |
| Acid-wielding worms drill through bones at the bottom of the sea Posted: 02 Jul 2012 10:48 AM PDT Tiny "bone-devouring worms," known to both eat and inhabit dead whale skeletons and other bones on the sea floor, have a unique ability to release bone-melting acid, scientists at have recently discovered. |
| New light shed on explosive solar activity Posted: 02 Jul 2012 10:47 AM PDT The first images of an upward surge of the sun's gases into quiescent coronal loops have been identified by an international team of scientists. The discovery is one more step towards understanding the origins of extreme space storms, which can destroy satellite communications and damage power grids on Earth. |
| 'Trophy molecule' breakthrough may result in cleaner, cooler nuclear energy Posted: 02 Jul 2012 10:35 AM PDT Experts have created a stable version of a 'trophy molecule' that has eluded scientists for decades. They have prepared a terminal uranium nitride compound which is stable at room temperature and can be stored in jars in crystallized or powder form. The breakthrough could have future implications for the nuclear energy industry — uranium nitride materials may potentially offer a viable alternative to the current mixed oxide nuclear fuels used in reactors since nitrides exhibit superior high densities, melting points, and thermal conductivities and the process the scientists used to make the compound could offer a cleaner, low temperature route than methods currently used. |
