West Nile Virus Transmission - New Insights

in medicine, biology

West Nile virus can infect a wide range of animals, but only a few key species of bird "hosts" and mosquito "vectors" are important in transmission of the virus, according to an article published in Science.  West Nile virus spread across the United States in just a few years after its initial appearance in New York in 1999.  The virus is now well established throu

Malaria Vaccine Becoming Reality

in medicine

A new malaria vaccine provided significant protection against malaria in African children, according to a clinical trial report published in the New England Journal of Medicine. This could be the first effective vaccine against malaria.

Ultra-Strong, Flexible Carbon Nanotube Artificial Muscle Invented

in technology, medicine

A team of scientists have invented new artificial muscles strong enough to rotate objects a thousand times their own weight, but with the same flexibility of an elephant’s trunk or octopus limbs.  The new twisting artificial muscle could be used for propelling nano robots.

Neuronal Output Of Emotions - Neural Basis Of Face Recognition

in medicine, biology

Neuroscientists have discovered a novel response to human faces by looking at recordings from brain cells in neurosurgical patients. The finding provides the first description of neurons that respond strongly when the patient sees an entire face, but respond much less to a face in which only a very small region has been erased.

Alzheimer’s Disease Without Amyloid Plaques

in medicine, biology

Amyloid plaques have long been thought to be the cause of neuron loss in Alzheimer’s disease.  Now researchers report that excess of mutated amyloid precursor protein (APP) inside the neurons is sufficient to induce neuron death.  The report challenges the notion that amyloid deposits outside of the cells are necessary for neuron death in Alzheimer’s disease.

New Light-Sensitive Polymer For Use In Non-Invasive Surgical Procedures Developed

in technology, medicine

Scientists at the University of California, San Diego have developed what they believe to be the first polymeric material that is sensitive to biologically benign levels of near infrared (NRI) irradiation, enabling the material to disassemble in a highly controlled fashion.

Singing After Stroke? Don’t Ignore Rhythm

in medicine, biology

When a stroke damages speech areas in the brain’s left hemisphere, sufferers often have severe difficulties speaking – a condition known as non-fluent aphasia. A new study published in the journal Brain may lead the way to new rehabilitative therapies for the speech disorders.
