New Self-Cloning Lizard Found in Vietnam Restaurant {*style:<b>You could call it the surprise du jour: A popular food on Vietnamese menus has turned out to be a lizard previously unknown to science, scientists say. </b>*} What's more, the newfound is no run-of-the-mill reptile —the all-female species reproduces via cloning, without the need for male lizards. Single-gender lizards aren't that much of an oddity: About one percent of lizards can reproduce by parthenogenesis, meaning the females spontaneously ovulate and clone themselves to produce offspring with the same genetic blueprint.

Empress Royal Paulownia Tree Step 1: Dig the hole Pick the perfect spot with full or partial sunlight and with moist or well drained soil. Dig the hole so it is shallower than the root ball and at least twice the width. Loosen the soil in the planting hole so the roots can easily break through. Drag the point of a shovel along the sides and bottom of the hole. What is a Salt Glacier? A moving river of crystalline salt. What Are Salt Glaciers? In the Zagros Mountains of Iran, salt domes break through the surface to produce flowing glaciers of salt. The arid climate does not produce enough rain to dissolve the salt and carry it away. Most people are familiar with ice glaciers.

Spinning-disk microscope offers window into the center of cell A new method of imaging cells is allowing scientists to see tiny structures inside the 'control centre' of the cell for the first time. The microscopic technique, developed by researchers at Queen Mary University of London, represents a major advance for cell biologists as it will allow them to investigate structures deep inside the cell, such as viruses, bacteria and parts of the nucleus in depth. Recent advances in optical physics have made it possible to use fluorescent microscopy to study complex structures smaller than 200 nanometres (nm) -- around 500 times smaller than the width of a human hair. These methodologies are called super-resolution microscopy. The drawback of such techniques is that they can only produce very clear images of structures that are at the bottom of the cell.

That is two million people enjoying humankind's ability to look at an animal and think we know how it is feeling. We love sledding. Birds love sledding. We love birds that love sledding.

You Can Look It Up - Geologic Words When you get into geology, as opposed to rockhounding, the first thing you need is a dictionary. There are so many different things to keep track of—landforms, minerals, fossils and the parts of fossils—and so many of the words aren't English. Great language though it is, English just isn't up to the task. First, Go Native Lots of non-English words stand for geologic things that English speakers never knew about. Bats Use Rolled-Up Leaves as “Trumpets” By Ker Than- A species of tiny bat seems to be using rolled-up leaves like trumpets to amplify calls, a new study says. A few years ago, biologists Gloriana Chaverri and Erin Gillam were in Costa Rica studying Spix’s disk-winged bat, a species that is known to escape predators and harsh weather by roosting inside the folded leaves of plants such as the lobster-claws plant and calatheas. Disk-winged bats inside leaves on Barro Colorado Island, Panama. Photograph by Christian Ziegler, National Geographic The creatures are so small—each one weighs only about four grams—that multiple bats can fit inside a single leaf.

All Non-Africans Part Neanderthal, Genetics Confirm If your heritage is non-African, you are part Neanderthal, according to a new study in the July issue of Molecular Biology and Evolution. Discovery News has been reporting on human/Neanderthal interbreeding for some time now, so this latest research confirms earlier findings. Damian Labuda of the University of Montreal's Department of Pediatrics and the CHU Sainte-Justine Research Center conducted the study with his colleagues. They determined some of the human X chromosome originates from Neanderthals, but only in people of non-African heritage.

Red Rain in India May Have Alien Origin By Arshdeep SaraoEpoch Times Staff Created: August 6, 2012 Last Updated: August 11, 2012 This red rain sample from 2001 contains a thick suspension of cells that lack DNA and may originate from cometary fragments. (Godfrey Louis/CUSAT) A rare shower of red rain fell for about 15 minutes in the city of Kannur, Kerala, India, early on June 28. Local residents were perturbed, but this is not the first time the state has experienced colored rain.
