Scientists have determined the most detailed picture yet of a crucial part of the hepatitis C virus, which the virus uses to infect liver cells. The new data reveal unexpected structural features of this protein and should greatly speed efforts to make an effective hepatitis C vaccine.
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
Computer engineers and hearing scientists at The Ohio State University have made a potential breakthrough in solving a 50-year-old problem in hearing technology: how to help the hearing-impaired understand speech in the midst of background noise.
A multi-institutional research team, led by Johns Hopkins engineers, says it has solved the puzzle of why animals push in directions that don’t point toward their goal, like the side-to-side sashaying of a running lizard or cockroach.
Imagine significantly reducing a persistent migraine or fibromyalgia by a visit to a doctor who delivers low doses of electricity to the brain. Scientists are optimizing the next generation for such a technique, called high-definition transcranial direct current stimulation, or HD-tDCS.
In a pair of landmark studies that exploit the genetic sequencing of the “missing link” cold virus, rhinovirus C, scientists have constructed a 3-D model of the pathogen that shows why there is no cure yet for the common cold.
In the fight to cure human immunodeficiency virus (HIV), researchers have been dealt a blow. A new study shows that the pool of inactive HIV viruses that lingers silently in a patient’s body is larger than expected.
Researchers have devised a hair restoration method that can generate new human hair growth, rather than simply redistribute hair from one part of the scalp to another.
A colorful wheel developed bioengineers to visualize protein interactions has won an international competition for novel strategies to study the roots of breast cancer.
A recent study by a University of Missouri researcher shows that resveratrol, a compound found in grape skins and red wine, can make certain tumor cells more susceptible to radiation treatment. This research, which studied melanoma cells, follows a previous MU study that found similar results in the treatment of prostate cancer.
A new study finds that some people are genetically predisposed to see the world darkly. The study finds that a previously known gene variant can cause individuals to perceive emotional events more vividly than others.
A dollop of peanut butter and a ruler to test for smell sensitivity can be used to confirm a diagnosis of early stage Alzheimer’s disease, researchers have found.
With high-tech optical tools and sophisticated mathematics, researchers have found a way to pinpoint the location of specific sequences along single strands of DNA, a technique that could someday help diagnose genetic diseases.
A new laser, the Supra Scan Multi-spot Laser, is helping experts provide better treatment for eye diseases. This advanced laser can prevent blindness for some patients with serious conditions. The first patient received treatment from the laser for proliferative diabetic retinopathy on July 22.
Scientists have moved closer to developing a universal flu vaccine by using the 2009 swine flu pandemic to study why some people seem to resist severe illness. Researchers asked volunteers to donate blood samples just as the pandemic was getting underway and also asked the volunteers to report any symptoms they experienced over the next two flu seasons.
