Scientists Identify Immune System Trigger For Fighting Lyme Disease
Researchers at the La Jolla Institute for Allergy &Immunology (LIAI) has announced an important finding on Lyme disease that could eventually lead to the development of a new vaccine to prevent this tick-borne disorder. Lyme disease is transmitted to humans by the bite of infected ticks. Typical symptoms include fever, headache, fatigue and sometimes skin rashes. If left untreated, it can spread to the joints, the heart and the nervous system and can lead to serious health problems. How Genetic Mutation Causes Epilepsy In Infants
The mutation in a single gene can cause epilepsy in infants. Infants are more susceptible to seizures because their brains are developing at a rapid rate, making their brain cells 'excitable'. Their neurons are growing and making new connections with other nerve cells, which can disrupt normal brain activity and results in epilepsy. Infants have protective mechanisms in their brains to control this excitability, but now the Florey scientists have uncovered that a single gene mutation prevents a specific ion channel from functioning correctly, thus causing excitability which results in epilepsy. Brain Compensatory Mechanisms Enhance The Recovery From Spinal Cord In
Brain compensatory mechanisms contribute to recovery from spinal cord injury. The basis of neurorehabilitation relies on the concept that training recruits remaining intact neuronal systems to compensate for partial injury to the spinal cord or brain. Taking A Bite Out Of The Problem: Researchers Devise Dinosaur Classifi
Josh Smith, PhD, assistant professor of earth and planetary sciences at Washington University in St. Louis, has concocted a mathematical scheme for identifying dinosaurs based upon measurements of their copious Mesozoic dental droppings. His method could help paleobiologists identify and reconstruct the lives of the creatures that roamed our terra firma many millions of years ago. Breast Cancer Recurrence Risk Test Cleared For Marketing
The U.S. Food and Drug Administration (FDA) has cleared for marketing a test that determines the likelihood of breast cancer returning within five to 10 years after a woman's initial cancer. It is the first cleared molecular test that profiles genetic activity. 'Killer petunias' should join the ranks of carnivorous plants, scienti
Scientists believe that carnivorous behavior in plants is far more widespread than previously thought, with many commonly grown plants -- such as petunias -- at least part way to being "meat eaters." Assessment Of Recent Rapid Land-cover Change Yields Portraits Of Globa
The February 2005 issue of BioScience, the monthly journal of the American Institute of Biological Sciences (AIBS), includes a new assessment of rapid land-cover change around the world over the period from 1981 to 2000. Changes in the use to which land is put have important implications for climate change and loss of biodiversity, and affect local populations' access to food and clean drinking water. Eating Seafood That Contains Toxic Substances Can Affect The Nervous S
Eating seafood containing toxic substances can have serious neurological as well as gastrointestinal effects, reveals a review in the April issue of THE LANCET NEUROLOGY. Quantum mechanics demonstrated in motion of objects large enough to se
Researchers have provided the first clear demonstration that the theory of quantum mechanics applies to the mechanical motion of an object large enough to be seen by the naked eye. Their work satisfies a longstanding goal among physicists. Penn Researchers Study The Use Of Ultrasound For Treatment Of Cancer
For the first time, ultrasound is being used in animal models -- to treat cancer by disrupting tumor blood vessels. Researchers at the University of Pennsylvania School of Medicine completed a study in mice in which they used ultrasound both to see a tumor's blood perfusion and then to treat it with a continuous wave of low-level ultrasound.
