Mayo Clinic study finds focused ultrasound treatment of uterine fibroids long term symptom relief
A noninvasive, outpatient treatment for noncancerous uterine tumors provides sustained relief from symptoms, according to a new Mayo Clinic led collaborative study. view more (2007-07-31)
Pain in fibromyalgia is linked to changes in brain molecule
Researchers at the University of Michigan Health System have found a key linkage between pain and a specific brain molecule, a discovery that lends new insight into fibromyalgia, an often-baffling chronic pain condition. view more (2008-03-11)
Implant bacteria, beware: Researchers create nano-sized assassins
Staphylococcus epidermidis is quite an opportunist. Commonly found on human skin, the bacteria pose little danger. But S. epidermidis is a leading cause of infections in hospitals. view more (2009-06-26)
Cultural stimulation changes the organization of the human brain
The development of a neurosciences project on the influence of culture on the organization of the functions of the brain, by Alexandre Castro-Caldas, brings us a perspective of life-long evolution and adaptation, demonstrating the importance of knowledge acquired at school age. The analysis of the acquisition and performance in the areas of... view more... (2002-11-18)
New magnets with 99% air content
Researchers from the Physics Department at the Universitat Autònoma de Barcelona (UAB), the Institut de Cie'nca de Materials de Barcelona (ICMAB-CSIC), and the Universidad de Zaragoza have created a new ultra-light transparent magnetic material. Thanks to its properties, the new material could have interesting technological applications,... view more... (2003-11-25)
New rotors could help develop nanoscale generators
In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level. view more (2009-05-28)
Neutron researchers discover widely sought property in magnetic semiconductor
Researchers working at the National Institute of Standards and Technology (NIST) have demonstrated for the first time the existence of a key magnetic-as opposed to electronic-property of specially built semiconductor devices. view more (2008-11-26)
Oxygen + MRI might help determine cancer therapy success
A simple magnetic resonance imaging (MRI) test involving breathing oxygen might help oncologists determine the best treatment for some cancer patients, report researchers at UT Southwestern Medical Center. view more (2009-06-03)
Improved Spin Transistor from Oxford University
Researchers at Oxford University’s Physics Department have developed an improved version of the “spin transistor,” a device which has the principle operating characteristics of a conventional transistor but with the added benefit of a current output dependent on the strength of the external magnetic field. This exciting new... view more... (2002-08-15)
External Magnetic Field Causes The Puzzling Heating Of The Solar Corona
The Russian astrophysicists have theoretically modelled coronal loop oscillations and have shown that the plasma present in coronal loops is quite "normal". So, the puzzle of the Sun`s atmosphere heating remains unresolved. Coronal loops, immense magnetic arches more hot and dense than the coronal... view more... (2002-06-21)
Transition Metal Selenites (Mn, Co, Ni, Fe, Cu, Zn and Cd)
The work involved a multidisciplinary task, undertaking the study of phases of mineralogical and physico-chemical interest. Selenites were synthesised, given that they are a new field and likely to present original physical properties. view more (2005-09-30)
Toxic substances when cooking fats and oils?
Consumers' food health and safety may be affected by the presence of micro-organisms and toxic substances in foodstuffs. The cause of the presence of toxic substances in food is sometimes due to the fact that these have been subject to processes of degradation. The oxidation or thermal degradation of food lipids causes deterioration in foodstuffs... view more... (2005-05-25)
Researchers map links between size of hippocampus and progression to Alzheimer's dementia
UCLA researchers sought to test the theory that the hippocampus - the area of the brain that processes memory - is smaller in patients with mild cognitive impairment who develop into Alzheimer's dementia, and that it is larger in patients with mild cognitive impairment who experience cognitive stability or improvement. view more (2006-05-09)
Appropriateness criteria issued for cardiac computed tomography, cardiac magnetic resonance imaging
he American College of Cardiology Foundation (ACCF) along with key specialty and subspecialty societies have released Appropriateness Criteria for two relatively new clinical cardiac imaging modalities, cardiac computed tomography (CCT) and cardiac magnetic resonance imaging (CMR). view more (2006-08-08)
Use of breast MRI can be cost-effective for some women at high-risk of breast cancer
A computer model simulation suggests that adding breast MRI screening may be cost-effective for women of certain ages who carry BRCA1 and BRCA2 gene mutations. view more (2006-05-24)
Changing the rings: a key finding for magnetics design
Researchers at the National Institute of Standards and Technology's Center for Nanoscale Science and Technology (CNST) have done the first theoretical determination of the dominant damping mechanism that settles down excited magnetic states-"ringing" in physics parlance-in some key metals. view more (2007-08-06)
Thermal treatment for magneto-resistant materials design
Reader heads of compact discs and computer hard discs or position and magnetic field sensors are some of the applications of magneto-resistant materials, which are normally obtained by costly methods. Precisely in order to solve this problem, university teacher Mar'a Luisa Fern'ˇndez-Gubieda Ruiz, of the University of the Basque Country, is... view more... (2003-07-09)
New magnetic separation technique might detect multiple pathogens at once
A magnetic separation technique developed by researchers at Duke University's Pratt School of Engineering and Purdue University makes it relatively simple to sort through beads hundreds of times smaller than the period at the end of this sentence. view more (2007-10-30)
Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals
Magnetic orientation is critical to the migratory success of many bird species. By studying the influence of light on the ability of migratory birds to orient to magnetic signals, researchers have found clues to suggest that birds' orientation abilities may be more complex than previously thought. view more (2005-08-23)
