Their goal - to finally find out what these "North Pole wolves" do in the long, dark days of winter in one of the harshest areas of the world. http://www.physorg.com/news178892666.html Biology Tue, 01 Dec 2009 13:10:04 EST news178892666 (PhysOrg.com) -- An extinct goat that lived on a barren Mediterranean island survived for millions of years by reducing in size and by becoming cold-blooded, which has never before been discovered in mammals. http://www.physorg.com/news177755291.html Biology Wed, 18 Nov 2009 08:28:58 EST news177755291 (PhysOrg.com) -- Bad news for the immune system: New research has boosted the number of likely common-cold viruses waiting to make you miserable from the long-accepted 100 to perhaps double that number. http://www.physorg.com/news175185168.html Medicine & Health Mon, 19 Oct 2009 15:33:44 EST news175185168 Many wheelchair-using children with neurological disorders have much colder hands and feet than other children, and most receive no special help even though they have had these problems for a long time, is revealed in at thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. http://www.physorg.com/news175177435.html Medicine & Health Mon, 19 Oct 2009 13:25:03 EST news175177435 (PhysOrg.com) -- UQ scientist Ian Mackay is always on the lookout for that lucky find - well, if you consider unknown strains of the common cold virus lucky. http://www.physorg.com/news173963366.html Medicine & Health Mon, 05 Oct 2009 14:10:02 EST news173963366 Physicists are continually reaching new lows as they reduce the temperatures of samples in their laboratories. But even nano-kelvins are not low enough to overcome the entropy (a measure of the disorder in a system) that stands between them and the discovery of exotic states of ultra-cold matter. http://www.physorg.com/news173353018.html Physics Mon, 28 Sep 2009 10:50:02 EST news173353018 Strawberries are America's fifth-favorite fruit, according to consumption rates. California and Florida grow more than 95% of the nation's strawberries; an additional 12,000 acres are planted in other states. Strawberries are increasingly grown on small-scale farms in direct-to-consumer markets, which are gaining popularity as part of the emerging "local food movement". But how do growing methods designed to ensure successful strawberry production in colder climates affect the environment? http://www.physorg.com/news171285093.html Space & Earth Sat, 05 Sep 2009 08:20:01 EST news171285093 Species living in restricted environments such as the tropics may lack adequate variation in their genes and be unable to adapt to climate change, according to a new study. http://www.physorg.com/news171207668.html Biology Thu, 03 Sep 2009 15:30:01 EST news171207668 Two days ago, Hilda was in prime shape to strengthen further as she tracked westward, far south of the Hawaiian Islands. Today, as a result of winds and cooler waters, she's weakened to a tropical depression, and NASA satellites helped confirm that looking at her waning winds and thunderstorms. http://www.physorg.com/news170594576.html Space & Earth Thu, 27 Aug 2009 12:40:01 EST news170594576 The adult lower digestive tract can be stimulated to add neurons to the intestinal system, according to new mouse research in the August 5 issue of The Journal of Neuroscience. The study shows that drugs similar to the neurotransmitter serotonin increase the production of new neurons in the gut. This is the first research to confirm that an adult intestine can generate neurons in the enteric nervous system, the network of neurons in the gut's wall that controls the gastrointestinal system. http://www.physorg.com/news168627007.html Medicine & Health Tue, 04 Aug 2009 17:50:33 EST news168627007 (AP) -- Government experts are scheduled to vote on whether Nyquil and other combination cold medications should be pulled from the market to help curb deadly overdoses. http://www.physorg.com/news165555611.html Medicine & Health Tue, 30 Jun 2009 05:40:01 EST news165555611 Diviner, an instrument that will make the first maps of the temperature on the surface of the lunar polar regions, entered the moon's orbit this morning (June 23) aboard NASA's Lunar Reconnaissance Orbiter. http://www.physorg.com/news165080293.html Space & Earth Wed, 24 Jun 2009 19:40:02 EST news165080293 The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth's atmosphere, says new Cornell University research.

This is because the feedback normally produced by a cavity, which sets a propagation axis, is now provided by multiple scattering in all directions. Light is randomly scattered throughout the structure of the laser, exciting further light-emitting processes. Light in a random laser does not come out in a precise direction; it comes out in all directions.` http://www.physorg.com/news161863563.html Physics Mon, 18 May 2009 11:06:44 EST news161863563 (PhysOrg.com) -- When studying cold atoms, scientists often use magnetic or optical traps to keep the atoms in place. However, in some cases experimentalists want to study free atoms, avoiding the effects of a trap. "One way to study free atoms," Cass Sackett tells PhysOrg.com, "is by bouncing them off a surface... most of the time, the atoms are free." He says that scientists have been interested in bouncing atoms for a long time, but that before now only about five bounces have been achieved. "Using magnets and certain lasers, it is possible to bounce atoms. However, they are lost relatively quickly." http://www.physorg.com/news160053848.html Physics Mon, 27 Apr 2009 12:24:47 EST news160053848 (AP) -- Doctors are warning parents to avoid using imported camphor products after poisonings in several New York City children. http://www.physorg.com/news160030516.html Medicine & Health Mon, 27 Apr 2009 05:55:52 EST news160030516 An expansion of wetlands and not a large-scale melting of frozen methane deposits is the likely cause of a spike in atmospheric methane gas that took place some 11,600 years ago, according to an international research team led by Scripps Institution of Oceanography at UC San Diego. http://www.physorg.com/news159715281.html Space & Earth Thu, 23 Apr 2009 14:21:49 EST news159715281 (PhysOrg.com) -- The most accurate timekeepers in the world are atomic clocks, which tell time based on the absorption of a very specific and unchanging microwave frequency, which induces electrons in an atom to `jump` from one particular energy level to another. But to improve atomic clocks further, a new basis is needed. http://www.physorg.com/news159624756.html Physics Wed, 22 Apr 2009 13:13:10 EST news159624756 A clock that is so precise that it loses only a second every 300 million years - this is the result of new research in ultra cold atoms. The international collaboration is comprised of researchers from the University of Colorado, USA and the Niels Bohr Institute at the University of Copenhagen and the results have just been published in the prestigious scientific journal, Science. http://www.physorg.com/news159111429.html Physics Thu, 16 Apr 2009 14:37:36 EST news159111429 (PhysOrg.com) -- Forget dancing angels, a research team from the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) has shown how to detect and monitor the tiny amount of light reflected directly off the needle point of an atomic force microscope probe, and in so doing has demonstrated a 100-fold improvement in the stability of the instrument`s measurements under ambient conditions. Their recently reported work* potentially affects a broad range of research from nanomanufacturing to biology, where sensitive, atomic-scale measurements must be made at room temperature in liquids. http://www.physorg.com/news157206337.html Nanotechnology Wed, 25 Mar 2009 13:26:26 EST news157206337 Researchers are reporting compelling new scientific evidence for the existence of low-energy nuclear reactions (LENR), the process once called "cold fusion" that may promise a new source of energy. One group of scientists, for instance, describes what it terms the first clear visual evidence that LENR devices can produce neutrons, subatomic particles that scientists view as tell-tale signs that nuclear reactions are occurring. http://www.physorg.com/news157046734.html Physics Mon, 23 Mar 2009 17:06:19 EST news157046734 A new study by Brigham Young University researchers on the virus behind nearly half of all cold infections explains how and where evolution occurs in the rhinovirus genome and what this means for possible vaccines. http://www.physorg.com/news156436585.html Biology Mon, 16 Mar 2009 15:37:19 EST news156436585 Rutgers AIDS researchers Gail Ferstandig Arnold and Eddy Arnold may have turned a corner in their search for a HIV vaccine.

These viruses usually cause symptoms similar to the common cold, or vomiting and diarrhoea. However, the team has now provided clear evidence that they are also found frequently in the pancreas of people who develop diabetes. http://www.physorg.com/news155486297.html Medicine & Health Thu, 05 Mar 2009 14:38:54 EST news155486297 A key item in the developmental agenda of a plant leaf is the establishment of an axis that makes a leaf's top half distinct from its bottom half. This asymmetry is crucial for the leaf's function: it ensures that the leaf develops a flattened blade that is optimized for photosynthesis, with a top surface specialized for light harvesting and a bottom surface containing tiny pores that serve as locales for gas exchange. http://www.physorg.com/news155132111.html Biology Sun, 01 Mar 2009 12:15:57 EST news155132111 Newborns whose first few months of life coincide with high pollen and mold seasons are at increased risk of developing early symptoms of asthma, suggests a new study led by researchers at the University of California, Berkeley. http://www.physorg.com/news154684858.html Medicine & Health Tue, 24 Feb 2009 08:01:30 EST news154684858
