04/30/05 - Spray-On Skin To make the spray, the researchers mixed ethanol and a biodegradable polymer-such as polylactic acid-in a small semiconducting container, and then gave it an electric charge by putting an electric field across the container. Because the wound is at a far lower electrical potential than the polymer, the solution is attracted to the skin surface and flies out through tiny nozzles, producing fine, light fibres, each of them 5 micrometres in diameter. The fibres have the same charge so they repel each other, making them regularly spaced. "What you get is like a spider's web," says Electrosols researcher Ron Coffee, who is currently developing a hand-held version of the spray. It looks like a fat pen about 2.5 centimetres across and about 15 centimetres long, and could be used by paramedics or kept in first-aid kits, he says. 04/30/05 - Radical new antenna improvements Vincent's Plano Spiral Top Hat antenna at 7 megahertz is half the size of a normal quarter-wave antenna operating at that frequency. The URI antenna gain matched the performance of the ideal quarter-wave antenna, and its bandwidth was nearly twice as wide. This type of antenna has multiple uses, including military, marine, amateur radio communications and AM broadcasting. In addition, the gain of Vincent's capacity Top Hat DLM antenna, which incorporates a helix, a load coil, a capacitive top hat utilizing radial spokes at the top of the antenna and a horizontal plane was nearly identical to the ideal quarter wave antenna. Its bandwidth was greater than 5 percent of the operating frequency and the antenna is more than 70 percent shorter than an ideal quarter wave antenna. 04/27/05 - Bubble power - fusion energy producing device For several years, Taleyarkhan and Lahey have been working to improve their sonofusion method. They apply sound waves to a deuterium-rich liquid inside which tiny bubbles filled with deuterium vapor grow and then implode. The bubbles' violent collapse can cause some of the deuterium nuclei they contain to undergo fusion. 04/27/05 - Using kids play to pump water! South African company Roundabout Outdoors has designed a playground roundabout that powers a borehole pump. Children spinning the roundabout at up to 16 revolutions a minute can raise 1400 litres of water an hour from a depth of 40 metres, says company spokesman Trevor Field. The positive displacement water pump is effective down to 100 metres, and costs around $900. 04/24/05 - Dimensional Communicator The following describes, in simple terms, what the present invention actually does. The present invention takes a transmission of energy, and instead of sending it through normal time and space, it pokes a small hole into another dimension, thus, sending the energy through a place which allows transmission of energy to exceed the speed of light. 04/23/05 - Living metals - micro fluctuations in crystalline materials For a fixed temperature, however, the x-ray diffraction pattern has hitherto always been found to be static according to standard textbook wisdom. The novel observation is now that this x-ray diffraction pattern shows fluctuations in time when the beam is focused to a very small size of a few micrometers. This gives clearcut evidence that temporal structural fluctuations on an atomic scale are present in the crystal. By using a very small beam, the number of the temporal fluctuations "seen" by the x-ray beam is so small that these fluctuations now become visible as x-ray intensity fluctuations. 04/23/05 - Induced human hibernation using hydrogen sulphide The trick with the mice didn't require freezing. Instead, the rodents breathed air laced with hydrogen sulfide, a chemical produced naturally in the bodies of humans and other animals. Within minutes, they stopped moving and soon their cell functions approached total inactivity. Humans use hydrogen sulfide to "buffer our metabolic flexibility," Roth explained. "It's what allows our core temperature to stay at 98.6 degrees, regardless of whether we're in Alaska or Tahiti." In extreme doses, the hydrogen sulfide is thought to bind to cells in place of oxygen. The organism's metabolism shuts down. Upon breathing normal air again, the mice "quickly regained normal function and metabolic activity with no long-term negative effects," the researchers report. 04/23/05 - Spectral Nose sniffs out diseases "Where diseases are associated with characteristic odours, this could be used for rapid screening and mass screening. "Smallpox, liver failure, diabetes - there are a lot of things you can pick up just from the smell of a patient's breath," he said. "Even measles has a characteristic smell. 04/22/05 - HyperSonic Sound - new sound transducer technology It works by sending a focused beam of sound above the range of human hearing. When it lands on you, it seems like sound is coming from inside your head. 04/22/05 - Air conditioning from exhaust sounds What's involved is a sealed steel and aluminium tube, about 50 millimetres in diameter and one metre long. Inside the tube are two components. First there is a thermoacoustic heat engine that converts heat from the car exhaust, with temperatures up to 10000C, into soundwaves. The sound waves bounce off the end of the tube and are amplified to around 180 decibels. 04/18/05 - Phototherapy works as well as drugs "But when you throw out all the studies that are methodologically flawed and then conduct a meta-analysis of those that are well-designed, you find that light therapy is an effective treatment not only for SAD but also for depression." The use of bright artificial light for people with SAD, a recurring depression that develops in the fall or winter and spontaneously disappears during spring or summer, was first described in the Archives of General Psychiatry in 1984. 04/17/05 - Creativity Machine - incredible learning, predictive AI software!!! Thaler's technology was born from near-death experiences of dying computer programs. Its foundation is the discovery that great ideas are the result of noisy neurons and faulty memories. Thaler built another neural network and trained it to recognize the structure of diamonds and some other super-hard materials. He also built a second network to monitor the first one's activities. Then he tickled a few of the network's connections, and something began to happen. The tickling, akin to a shot of adrenaline or an electrical jolt in the brain, produced noise. In this sense, noise is not sound, but random activity. And the noise triggered changes in the network. The result was new ideas. The computer dreamed up new ultra-hard materials. Some of the materials are known to humans, but Thaler didn't tell the network they existed. Other materials are entirely new, unknown to humans or computers before. 04/15/05 - Storing water in brass for 'healthy' water Reed, with his colleagues Puja Tandon and Sanjay Chhibber, carried out two series of experiments. In Britain, the researchers filled brass and earthenware vessels with a diluted culture of escherichia coli bacteria, which can cause illnesses such as dysentery. They then counted the surviving bacteria after 6, 24 and 48 hours. A similar test was carried out in India using naturally contaminated water. "The amount of live e-coli in the brass vessels dropped dramatically over time, and after 48 hours they fell to undetectable levels,'' Reed told the Society for General Microbiology's meeting. 04/14/05 - New thermal equilibrium phenomena Here's how you can generate heat or electricity in contrary phenomena. In the Peltier effect, a voltage imbalance will pull electrons and holes out of one of the junctions, thus cooling that junction and warming the other junction. In the Seebeck effect, things work in reverse: a temperature imbalance between the junctions will set electrons and holes in motion, thus constituting an electric current. 04/14/05 - Ozone - superbug killer and sterilizer 99.9% effective It says the method, using an electronically produced gas-like vapour, which bathes surfaces, including fabrics, is effective in destroying 99.99 per cent of bacteria such as listeria and E.coli, and is ideal for the food industry, making the industrial preparation of food safer and more hygienic. 04/14/05 - Hydrogen 'cat-flap' allows storage at low pressures Hydrogen is injected at high pressure into the tiny pores in specially designed materials that act as a 'sponge' for the gas. Pressure within the material is then reduced, allowing the hydrogen to remain safely in place without the risk of an explosion. Heat can be applied to release the hydrogen from the porous material when it is needed. 04/14/05 - Heating system creates its own electricity supply The unit, called WhisperGen, is powered by a mains gas supply to provide heating and hot water like a conventional boiler. But is also produces its own electricity to power lights and other electrical equipment in homes, by converting excess heat that normally escapes through the exhaust flue of a conventional boiler, into electricity. Powergen also says that surplus electricity generated can be sold back to them - a two-way system allows electricity to be imported and exported from a house, with a special meter keeping a record of this, and the company buying back any surplus generated. 04/11/05 - black holes do not exist - gravity controls time In general relativity, there is no such thing as a `universal time' that makes clocks tick at the same rate everywhere. Instead, gravity makes clocks run at different rates in different places. 04/08/05 - New way to increase water conductivity Professor Ric Pashley of the Australian National University in Canberra has found that removing tiny amounts of nitrogen and oxygen from water dramatically increases its ability to conduct electricity. 04/04/05 - Nautilus and seashells don't follow the golden ratio In 1999, when Falbo measured nautilus shells in a collection at the California Academy of Sciences in San Francisco, he found that the spirals of these shells could be inscribed within rectangles with sides in the ratio of about 1.33151; not 1.618 . . . , as they would be if a spiral based on the golden ratio matched the shell shape. Roughly speaking, the spiral of the chambered nautilus triples in radius with each full turn whereas a golden-ratio spiral grows by a factor of about 6.85 per full turn. 04/01/05 - Battery Recharges in only One Minute The company's new battery can recharge 80% of a battery's energy capacity in only one minute, approximately 60 times faster than the typical lithium-ion batteries in wide use today, and combines this fast recharge time with performance-boosting improvements in energy density.
