New research sheds light on the question of which cells support viral replication and persistence, and the answers have implications for future efforts to eliminate HIV from the body in human patients.
An antibody abundant in mice and previously thought to offer poor assistance in fighting against infection may actually play a key role in keeping immune responses in check and preventing more serious self-inflicted forms of kidney disease, researchers say.
New research dramatically alters the prevailing theory of how Alzheimer’s disease develops. The research also helps explains why some people with plaque buildup in their brains don’t develop dementia, and shows the potential of a cancer drug to combat the disease.
People who are shorter than average height have an increased risk of dying with dementia, a study has found. Researchers examined several health studies of the general population, which recorded health information such as blood pressure, height, weight and risk factors for ill health.
Philanthropist Bill Gates says he wants to end malaria in his lifetime and will give more money toward that goal, part of his broader fight against tropical diseases that are getting unusual public attention because of the Ebola epidemic.
Top medical experts studying the spread of Ebola say the public should expect more cases to emerge in the United States by year's end as infected people arrive here from West Africa, including American doctors and nurses returning from the hot zone and people fleeing from the deadly disease.
A new study has identified a potential target for therapies to treat cocaine addiction. Investigators found evidence that changing one amino acid in a subunit of an important receptor protein alters whether cocaine-experienced animals will resume drug seeking after a period of cocaine abstinence.
A study has identified for the first time changes in the metabolic activity of a key brain region in patients successfully treated for depression with psychodynamic psychotherapy.
Researchers have developed a new genetic strain of mice that will significantly improve opportunities to test the initial efficacy of potential vaccines and treatments for Ebola and other emerging pathogens.
Forty million people worldwide are living with Alzheimer’s and this is only set to increase. But tiny brains grown in culture could help scientists learn more about this mysterious disease– and test new drugs.
Turns out your mom was right: Scratching an itch only makes it worse. New research from scientists indicates that scratching causes the brain to release serotonin, which intensifies the itch sensation.
New York City's disease detectives were off and running the moment the call came in from a doctor who suspected he had Ebola, highlighting the behind-the-scenes work of the city's team of sleuths, who track an outbreak at the source and seek to stop it from spreading.
Sleep apnea may affect your ability to form new spatial memories, such as remembering where you parked your car, new research suggests. The study demonstrates through the playing of a specific video game that disruption of rapid eye movement (REM) sleep as a consequence of sleep apnea impairs spatial memory.
Engineers have determined for the first time the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart. In order to make the study possible, researchers have developed a novel ultrasound technology that makes screening cheaper and much easier.
Scientists used pluripotent stem cells to generate functional, three-dimensional human stomach tissue in a laboratory– creating a new tool for researching the development and diseases of an organ central to several public health crises.
Two major genetic studies of autism have newly implicated dozens of genes in the disorder. The research shows that rare mutations in these genes affect communication networks in the brain and compromise fundamental biological mechanisms.
Who survives Ebola and why? Health workers treating patients in Sierra Leone, including some who died doing that work, have published the most detailed report yet on medical aspects of the epidemic. The research suggests young people are less likely to perish.
Mike Knutson taught himself to play the harmonica as a child, and the 96-year-old sang with his family for most of his life. Even now, as he suffers from dementia, music is an important part of his life— thanks to a study looking at the impact of a nationwide music program aimed at helping dementia patients.
The first embryonic stem (ES) cell trial for severe heart failure is launching now in Paris. The long-awaited trial comes after much preclinical cell work on more than 350 rats, 50 immunodeficient mice and 32 non-human primates.
A new breakthrough could help kidney stone sufferers get an exact diagnosis and specific treatment after genetic links to the condition were identified.
If melanoma, the deadliest form of skin cancer, is caught early enough it is almost always curable. Now, a camera capable of taking snapshots of the entire human body and rendering high-resolution images of a patient’s skin may help doctors spot cancer early and save lives.
In 2012, scientists captured national attention by identifying for the first time a group of people over 80 with remarkable, age-defying memory power. Now, the same scientists will continue studying these “SuperAgers” to find out how they resist cognitive decline.
Researchers have sequenced the genome of enterovirus D68 sampled from patients treated at St. Louis Children’s Hospital. Nationwide, the virus has spread rapidly in recent months.
A non-invasive blood test that could diagnose early-onset Alzheimer’s disease (AD) with increased accuracy has been developed by researchers. The new early-detection blood test could predict these changes and a person’s risk of developing AD much earlier than is currently possible.
Google is working on a cancer-detecting pill in its latest effort to push the boundaries of technology. Still in the experimental stage, the pill is packed with tiny magnetic particles, which can travel through a patient's bloodstream, search for malignant cells and report their findings to a sensor on a wearable device.
