30 Aug--Snowball Antarctica early Drake passage opening led to global change New results shed light on how Antarctica became the icy, barren continent that we know today. British Antarctic Survey (BAS) scientists have discovered that 30-50 million years ago, South America and Antarctica split apart very rapidly. This formed the Drake Passage and resulted in a major global cooling. The findings are published in the latest issue of Earth and Planetary Science Letters. EurekAlert

30 Aug--Gold bowties may shed light on molecules and other nano-sized objects One of the great challenges in nanotechnology is designing a microscope that produces high-resolution images of nano-sized objects. Now Stanford researchers have greatly improved the optical mismatch between nano-objects and light by creating the "bowtie nanoantenna," a tiny device that compresses ordinary light waves into an intense spotlight only 20 nanometers wide.  EurekAlert

30 Aug--New Look At DNA Hints At Origin Of Ultraviolet Damage Chemists at Ohio State University have gained new insight into how sunlight affects DNA. And what they found overturns ideas about genetic mutation that originated decades ago. In the current issue of the journal Nature, Bern Kohler and his colleagues report that DNA dissipates the energy from ultraviolet (UV) radiation in a kind of energy wave that travels up the edge of the DNA molecule, as if the energy were climbing one side of the helical DNA "ladder."

30  Aug--New Method For Trapping Light May Improve Communications Technologies A discovery by Princeton researchers may lead to an efficient method for controlling the transmission of light and improve new generations of communications technologies powered by light rather than electricity. The discovery could be used to develop new structures that would work in the same fashion as an elbow joint in plumbing by enabling light to make sharp turns as it travels through photonic circuits. Fiber-optic cables currently used in computers, televisions and other devices can transport light rapidly and efficiently, but cannot bend at sharp angles. ScienceDaily

The Image of dilutionLancet says the time for more studies is over and doctors should be bold and honest with patients about homeopathy's "lack of benefit". A Swiss-UK review of 110 trials found no convincing evidence the treatment worked any better than a placebo.

However, until now it has not been possible to train birds to move in a certain direction in the laboratory, even if they are motivated by a food reward. Researchers now report that they have been able to successfully accomplish this training task, providing new insight into the evolution of magnetic sensing and opening new opportunities for further study of magnetoreception.

UnderSmall boat on dyke - image courtesy Jassim Al-Asadi, Centre for the Restoration of Iraqi Marshlands, & Unep Saddam Hussein, the area of marsh was reduced to a tenth of its former size, as the government punished people living there for acts of rebellion.

24 Aug--Now You See It, Now You Don't: 'Change Blindness' Isn't Magic A team of scientists at UCL (University College London) has discovered why we often miss major changes in our surroundings - such as a traffic light turning green when we're listening to the radio. Our inability to notice large changes in a visual scene is a phenomenon often exploited by magicians - but only now can scientists put their finger on the exact part of the brain that is so often deceived.

Erik Trinkaus, professor of anthropology at Washington University in St. Louis, derived those dates by analyzing anatomical evidence of early modern humans, which suggests a reduction in the strength of the smaller toes in Upper Paleolithic humans while there was little change in leg strength.

This atmosphere is very similar to that of Jupiter's moons Europa and Ganymede. ScienceDaily

22 Aug--Carnegie Mellon University research reveals how cells process large genes Important messages require accurate transmission. Big genes are especially challenging. During processing, introns (non-coding elements) are snipped out and exons (coding segments) pasted together to form a template for proteins. How a cell's molecular machinery eliminates introns without making errors has puzzled scientists for years. Now, investigators at Carnegie Mellon have discovered that a novel mechanism removes long introns by steadily paring them down in a predictable fashion and joining the remaining exons. EurekAlert

19 Aug--Monkey Wrench In Solar System Evolution A University of Toronto scientist has found unexpectedly 'young' material in meteorites -- a discovery that breaks open current theory on the earliest events of the solar system. A paper published today in the August issue of Nature reports that the youngest known chondrules the small grains of mineral that make up certain meteorites have been identified in the meteorites known as Gujba and Hammadah al Hamra. Researchers who have studied chondrules generally agree that most were formed as a sudden, repetitive heat, likely from a shock wave, condensed the nebula of dust floating around the early Sun. Thinking that an analysis of the chondrules in Gujba and Hammadah al Hamra would be appropriate for accurately dating this process, U of T geologist Yuri Amelin, together with lead author Alexander Krot of the University of Hawaii, studied the chondrules mineralogical structure and determined their isotopic age. It soon became clear that these particular chondrules were not of a nebular origin, says Amelin. And the ages were quite different from what was expected. It was exciting.ScienceDaily

19 Aug--Nitrogen In The Air Feeds The Oceans A new study provides the first direct evidence that atmospheric nitrogen is an important nutrient for marine life.

18 Aug--How Butterflies Fly Thousands Of Miles Without Getting Lost Revealed By Researchers While "navigation" systems in automobiles are a fairly new (and still costly) innovation, monarch butterflies have managed for millennia to navigate their way for a distance of some 3000 miles (4800 kilometers) each fall from Canada to Mexico (and vice-versa in the spring) without losing their way. The phenomenon of long-range bird migration is a well-known one, but not in the insect world. Also, among birds their migration route is a round-trip one, which they make more than once in their lifetimes, while for the monarch it is strictly a one-way trip for each butterfly. How do these creatures do it? ScienceDaily
