A review of records from Children's Emergency Department revealed an average of five ornament-related injuries per year; more than half of these injuries involve a child eating fragments of these ornaments, including batteries and pieces of glass. http://www.physorg.com/news180039801.html Medicine & Health Mon, 14 Dec 2009 19:40:01 EST news180039801 (PhysOrg.com) -- Nature and its bottom-up processes for creating robust and responsive materials are inspiring new generations of synthetic materials and creative design. http://www.physorg.com/news179137286.html Biology Fri, 04 Dec 2009 08:22:22 EST news179137286 (PhysOrg.com) -- Like most animals, snails have either left- or right-handed asymmetry (chirality), both internally and externally, and the handedness is hereditary. A new study has for the first time found that handedness, as seen in the direction of a snail shell spiral, can be reversed by manual manipulation of eight cell stage embryos, which is much earlier than previously thought. http://www.physorg.com/news178786914.html Biology Mon, 30 Nov 2009 07:03:02 EST news178786914 Deep under the sea, there's a battle of life and death going on, with no holds barred. Sponges and other marine animals which cannot move around might seem to be defenceless against predators. Yet nothing is further from the truth. These animals produce biologically active chemical substances which provide them with an effective defence against their enemies. http://www.physorg.com/news177947175.html Biology Fri, 20 Nov 2009 14:10:02 EST news177947175 Like other users of microfluidic systems, National Institute of Standards and Technology researcher Javier Atencia was faced with an annoying engineering problem: how to simply, reliably and most of all, tightly, connect his tiny devices to the external pumps and reservoirs delivering liquids into the system. While pondering this one day, he randomly picked up two magnets and began playing with them. As the magnets pulled apart and then snapped back together, Atencia realized that he had his solution. http://www.physorg.com/news177761689.html Physics Wed, 18 Nov 2009 11:00:02 EST news177761689 A team of physicists has, for the first time, seen convincing experimental evidence for directed percolation, a phenomenon that turns up in computer models of the ways diseases spread through a population or how water soaks through loose soil. Their observation strengthens the case for directed percolation's relevance to real systems, and lends new vigor to long-standing theories about how it works. Their experiment is reported in Physical Review E and highlighted with a Viewpoint in the November 16 issue of Physics. http://www.physorg.com/news177685136.html Physics Tue, 17 Nov 2009 13:10:02 EST news177685136 Scientists in Washington, DC, are reporting development and successful tests of a new way for exploring the insides of living cells, the microscopic building blocks of all known plants and animals.

This new technology is available in the Logitech Performance Mouse MX and the Logitech Anywhere Mouse MX, giving you the option of a full-size mouse or a more compact, notebook mouse. http://www.physorg.com/news169932194.html Electronics Wed, 19 Aug 2009 23:10:01 EST news169932194 Light is intangible and, in addition, it travels at great velocity. Nevertheless, it can be confined to a very small space by controllably inserting light into a microscopic container surrounded by reflective walls. The light will then be stored by continuous reflections and cannot escape. In the scientific domain, such a small reflective microcavity is termed a microresonator. These microresonators find applications in all areas where the interaction between light and matter shall be enhanced and studied in a controlled manner. An important area of usage is, for example, the laser diode, which has revolutionized telecommunications and optical data storage in the past few decades. http://www.physorg.com/news168074155.html Physics Wed, 29 Jul 2009 08:30:01 EST news168074155 Dye-sensitized solar cells (DSSCs) are expected to power Air Force unmanned aerial vehicles (UAVs) in the future because they are an optimum energy harvesting source that may lead to longer flight times without refueling. http://www.physorg.com/news166795115.html Technology Tue, 14 Jul 2009 12:58:58 EST news166795115 It may have once been part of a beer bottle.
