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...
Mimicking natural evolution in a test tube, scientists have devised an enzyme with a...
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.
Should every newborn baby girl be genetically screened for breast-cancer risk? That isn’t cost-effective— yet. But if it were, would it be worthwhile? A previous study said no. But, new research suggests otherwise.
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.
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.
A new study has allowed researchers to peer into unexplored regions of the genome and understand for the first time the role played by more than 250 genes key to cell growth and development.
When tissues are deprived of blood, as happens during a stroke or heart attack, the lack of oxygen can cause serious damage. A new study shows that surprisingly, a DNA-repair enzyme called Aag actually makes this damage worse.
A multi-institutional, international team of researchers studied cells found in breast and other types of connective tissue and discovered new information about cell transitions that take place during wound healing and cancer.
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.
Two recent papers may have upturned two common beliefs about adult stem cells: One reported that there appears to be stem cells in the esophagus, while the other reported that a fetal stem cell that can become either a liver cell or an endothelial cell.
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.
Starting Monday, millions of people who have avoided colon cancer screening can get a new home test that's noninvasive and doesn't require the icky preparation most other methods do. The test is the first to look for cancer-related DNA in stool.
A nurse who protested being kept in a tent in New Jersey over the weekend despite lacking symptoms after caring for Ebola patients in West Africa was to be released Monday as scientists and federal officials clashed with state officials over quarantine policies.
Researchers have now discovered that FLRT proteins on the surface of progenitor cells can induce repellent and attractant signals depending on its binding partner.
