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...
Researchers have developed a new genetic strain of mice that will significantly improve...
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.
In the Guinean village where the current West African Ebola outbreak began, 14 graves mark the spot where the lethal virus began to spiral out of control.
In 2010, a study reported the rapid detection of Ebola virus using new biosensor technology. There was little interest in developing the technology at the time, but now, in the wake of an Ebola outbreak, the researcher plans to resume his work on virus detection.
A new study points to a convenient, free way to manage acute asthmatic episodes— catching some rays outside. The research showed that asthmatics with vitamin D deficiency were 25 percent more likely to experience acute attacks.
Scientists have discovered an algae virus never before seen in the throats of healthy people that may subtly alter a range of cognitive functions including visual processing and spatial orientation in those who harbor it.
Amber Vinson, a nurse who fueled Ebola fears by flying to Cleveland after being infected by her dying patient in Dallas, is now virus-free, and was celebrated Tuesday by her caregivers as courageous and passionate before getting out of the hospital.
Radiotherapy is a primary, adjuvant or neoadjuvant treatment for a number of different cancers, such as glioblastoma, breast, lung and prostate. Image-guided radiation therapy (IGRT) is used to reduce the amount of radiation delivered to the normal tissue surrounding the targeted tumor. However, in the preclinical setting, the use of IGRT is less common.
Digoxin, a medication used in the treatment of heart failure, may be adaptable for the treatment of amyotrophic lateral sclerosis (ALS), a progressive, paralyzing disease, suggests new research.
Dietary cocoa flavanols—naturally occurring bioactives found in cocoa—reversed age-related memory decline in healthy older adults, according to a new study.
Researchers studying lipoproteins in Drosophila melanogaster found that that the blood-brain barrier is a main sensor to report the nutritional status, especially the lipid composition of consumed food, to special neurons that regulate insulin release.
New investigation methods using functional magnetic resonance tomography (fMRT) offer insights into fetal brain development. These in vivo observations will uncover different stages of the brain's development.
