Scientists have discovered infections that alter the behavior in plants, humans and other mammals. In the past, findings from the tomato plant concluded the majority of microbe behavior research. In the example of a tomato plant, a virus relies on a certain insect called a thrip, which jumps from plant to plant, sticking it’s oral probe into the plant’s cells to spread the virus.
Math problems are enough to sweat about for teachers and students, but new research has shown that early anxiety is often times associated with math. To be clear, math anxiety is more than just disliking math; someone with math anxiety feels negatively when engaging in activities involving numbers or math skills.
Gregory Berns and Sara Moore from the Center for Neuropolicy at Emory University have made a breakthrough in a phenomenon that has had us all scratching our heads: Why do certain songs get stuck in our heads? They have concluded that the strength of brain activity in teens could predict which songs would sell over 20,000 copies and which songs would not as calculated by Nielsen Standards.
Many people can close their eyes and imagine what life would be like if they were unable to see, but actually having a visual impairment is not that simple. Those with a visual impairment usually have some kind of residual visual, even if it is not very useful. Perceptions of light, peripheral vision, or blurry vision are just a few things that may be different for a person with a visual impairment.
Headaches are extremely common and have been experienced by most people at one time or another. The majority of headaches are tension headaches, which are irritating, but harmless. It is rare that people experience headaches that can be associated with severe, potentially life-threatening, neurological diseases such as meningitis, aneurysms and brain tumors.
Multiple Sclerosis (MS) is a chronic, inflammatory disease that attacks the central nervous system. The fatty myelin sheaths around the axons of the brain and spinal cord are damaged, leading to scarring. The beginning of the disease usually occurs in young adults, most commonly in women. In the United States today, there are 400,000 cases of MS, with 200 additional people diagnosed each week.
Spinal cord injuries are caused by a number of traumas to the spine. Anything from a car accident, fall, sporting injury, or assault can cause this type of injury. Minor trauma can also cause an injury to the spinal cord if the spine is already weakened. Direct injury can occur to the spinal cord, especially if the bones or the disks surrounding the cord have been damaged.
It used to be that if a soldier was wounded, he laid in the field where he had fallen without hope of being rescued. In 1862, Dr. Jonathan Letterman changed this by revamping the Army Medical Corps. He staffed and trained men to operate horse and wagon teams to pick up wounded soldiers and bring them back to field dressing stations for treatment. Considered the father of Modern Battlefield Medicine, Dr.
