Scientists are eager to make use of stem cells’ extraordinary power to transform into nearly any kind of cell, but that ability also is cause for concern in cancer treatment. Malignant tumors contain stem cells, prompting worries among medical experts that the cells’ transformative powers help cancers escape treatment.
A multidisciplinary research team discovers how cells know to rush to a wound and heal it – opening the door to new treatments for diabetes, heart disease and cancer. Researchers at the University of Arizona have discovered what causes and regulates collective cell migration, one of the most universal but least understood biological processes in all living organisms.
Dr. Nancy Snyderman said Thursday that she's leaving her job as chief medical editor for NBC News, six months after unleashing public anger for failing to observe a quarantine after covering the Ebola epidemic last fall.
Two groups have recently made strides with amyloid beta (aβ), the supposed main villain in Alzheimer’s disease. But while one group is tackling Alzheimer’s by reducing aβ, the other is tackling multiple sclerosis (MS) by using aβ.
An American healthcare worker who contracted Ebola while volunteering in a Sierra Leone treatment unit arrived safely at the National Institutes of Health's hospital in Maryland, officials announced early Friday.
Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles — a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
UCLA researchers have provided the first evidence that a simple blood test could be developed to confirm the presence of beta amyloid proteins in the brain, which is a hallmark of Alzheimer’s disease.
MIT study finds evidence that a new strain of H1N1 may carry dangerous mutations.
Can a tetanus shot help treat brain cancer? A small study hints that it might.
Queensland scientists have found that non-invasive ultrasound technology can be used to treat Alzheimer’s disease and restore memory.
Basal cell carcinomas develop mutations in a protein on the Hedgehog pathway to evade a common drug therapy. Targeting another portion of the pathway may be an effective alternative treatment.
A new study reveals an important connection between dozens of genes that may contribute to autism, a major step toward understanding how brain development goes awry in some individuals with the disorder.
Findings could help shed light on Alzheimer's, Parkinson's, ALS and other diseases.
Salk scientists re-engineered the bacterial defense system CRISPR to recognize HIV inside human cells and destroy the virus, offering a potential new therapy.
Discovery has implications for understanding epilepsy.
Apple teamed up with a handful of universities to create these medical research applications.
In the ongoing Ebola outbreak in West Africa, whose death toll is approaching 10,000, little information has been available about how the human immune response unfolds after infection. Researchers have now obtained a first look at the immune responses in four Ebola virus disease survivors who received care at Emory University Hospital in 2014, by closely examining their T cells and B cells during the acute phase of the disease.
A new study led by UNC researchers identifies both where in the brain and how a protein in the brain, called Neuropeptide Y or NPY, can act to suppress binge alcohol drinking. These findings suggest that restoring NPY may be useful for treating alcohol use disorders and may also protect some individuals from becoming alcohol dependent.
One of every eight patients might benefit from highly successful lymphoma drugs.
Getting a new drug to market is difficult, but the U.S. Food and Drug Administration (FDA) offers a number of ways to help the process along for promising drugs that have potential against serious diseases. One of these options is designation as a breakthrough therapy. This year a number of these therapies are targeted at fighting cancer.
People with anorexia nervosa and with body dysmorphic disorder have similar abnormalities in their brains that affect their ability to process visual information, a new UCLA study reveals.
In an advance that could lead to better identification of malignant pediatric adrenocortical tumors, and ultimately to better treatment, researchers have mapped the “genomic landscape” of these rare childhood tumors. Their genomic mapping has revealed unprecedented details, not only of the aberrant genetic and chromosomal changes that drive the cancer, but the sequence of those changes that trigger it.
Marking the progress in controlling its Ebola outbreak, the Liberian government dismantled a crematorium and removed drums containing the ashes of more than 3,000 Ebola victims cremated during the height of the epidemic, whose last patient was discharged last week.
Thyroid hormones have important and diverse roles in human health and regulate metabolic rate. Thyroid disease is common (affecting 5-10 per cent of the population) and synthetic thyroid hormones are one of the commonest drug therapies prescribed worldwide.
