Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 boosts the body’s natural defense against this ‘friendly fire.’
Sequencing the genomes of tumor cells has revealed thousands of genetic mutations linked with...
An experimental drug currently being trialled for influenza and Ebola viruses could have a new...
Veterinary research involving lambs at Iowa State University is helping to advance new treatments to a common virus in humans that sometimes poses a serious threat to newborns.
Almost a decade ago, scientists from Canada and the United States reported that they had created a vaccine that was 100 percent effective in protecting monkeys against the Ebola virus. The results were published in a respected journal, and health officials called them exciting.
Preexisting differences in the sensitivity of a key part of each individual’s immune system to stress confer a greater risk of developing stress-related depression or anxiety, according to a study conducted at the Icahn School of Medicine at Mount Sinai and published October 20 in the Proceedings of the National Academy of Sciences (PNAS).
Environmental Tectonics Corporation announced October 23 the recent award of a new contract totaling in excess of $1 million for the Sterilization Systems Group.
SmithGroupJJR, one of the nation’s largest architecture, engineering, and planning firms, has hired Scott Kreitlein, AIA, LEED AP, as leader of the Science & Technology Studio at its Phoenix office. He joins SmithGroupJJR from HDR, Houston, where he was science & technology principal.
A new animal study published in the Journal of Alzheimer’s Disease indicates that a diet including walnuts may have a beneficial effect in reducing the risk, delaying the onset, slowing the progression of, or preventing Alzheimer’s disease.
Blind cave fish may not be the first thing that comes to mind when it comes to understanding human sight, but recent research indicates they may have quite a bit to teach us about the causes of many human ailments, including those that result in loss of sight. A team of researchers is looking to the tiny eyeless fish for clues about the underpinnings of degenerative eye disease and more.
The Jackson Laboratory (JAX) has announced that technology investor David Roux and his wife Barbara have gifted $10 million to support research and find cures for genetically based diseases. The center will be based at the Laboratory’s locations in both Maine and Connecticut.
A new drug, known as OTS964, can eradicate aggressive human lung cancers transplanted into mice. The drug, given as a pill or by injection, inhibits the action of a protein that is overproduced by several tumor types, including lung and breast, but is rarely expressed in healthy adult tissues. Without this protein, cancer cells fail to complete the cell-division process and die.
Scientists have restored hearing in noise-deafened mice, pointing way to new therapies for humans. The research team shows the key role of protein called NT3 in ear-to-brain communication. These findings pave the way for research in humans that could improve treatment of hearing loss caused by noise exposure and normal aging.
Elvis did it, Michael Jackson did it, and so do the mitochondria in our cells. They shake. While Elvis and Michael shook for decades before loud and appreciative audiences, mitochondrial oscillations have quietly bewildered scientists for more than 40 years. Now, an NIH team has imaged mitochondria for the first time oscillating in a live animal - in this case, the salivary glands of laboratory rats.
A biopharmaceutical company has suspended its Huntington's disease clinical trial as it further evaluates an observation from a nonclinical study in rats. Non-human primates exposed to plasma concentrations equal to those in the rat demonstrated no findings similar to the observation reported from the rat study.
Salmonella-infected mice that were given antibiotics became sicker and began shedding far more bacteria in their feces than they had before. But some “superspreader” mice remained healthy, unaffected by either the disease or the antibiotic. The study poses ominous questions about the widespread, routine use of sub-therapeutic doses of antibiotics in livestock.
A new medical imaging method could help physicians detect cancer and other diseases earlier than before, speeding treatment and reducing the need for invasive, time-consuming biopsies. The potentially lifesaving technique uses nanotechnology to reveal small cancerous tumors and cardiovascular lesions deep inside the body. The researchers have demonstrated positive results in laboratory mice.
Researchers have used graphene, a two-dimensional form of carbon only one atom thick, to fabricate a new type of microelectrode that solves a major problem for investigators looking to understand the intricate circuitry of the brain. The team performed calcium imaging of hippocampal slices in a rat model with both confocal and two-photon microscopy, while also conducting electrophysiological recordings.
