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.
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.
As more states legalize medical marijuana, there's one stage in the process nobody wants to talk about: the part where people still have to break the law.
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.
A hormone seen as a popular target to develop weight loss drugs works by directly targeting the brain and triggering previously unknown activity in the nervous system, obesity researchers have found.
Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to an international team of scientists.
A new comprehensive analysis of thyroid cancer from The Cancer Genome Atlas Research Network has identified markers of aggressive tumors, which could allow for better targeting of appropriate treatments to individual patients.
Like a slumbering dragon, HIV can lay dormant in a person’s cells for years, evading medical treatments only to wake up and strike at a later time, quickly replicating itself and destroying the immune system. Scientists have now uncovered a new protein that participates in active HIV replication.
Researchers have uncovered the genes that are normally activated during recovery from bacterial infection. The finding could lead to ways to jumpstart this recovery process and possibly fend off autoimmune diseases and chronic inflammatory disorders.
The World Health Organization says millions of doses of two experimental Ebola vaccines could be ready for use in 2015 and five more experimental vaccines will start being tested in March.
Officials tried to tamp down New Yorkers' fears Friday after a doctor was diagnosed with Ebola in a city where millions of people squeeze into crowded subways, buses and elevators every day.
Physicians will tell you: They are not winning the war on ovarian cancer. But researchers have combined medicine and advanced nanotechnological engineering to create a smarter, more targeted therapy that could overcome the most lethal gynecologic cancer.
Using an innovative exome sequencing strategy, a team of international scientists has shown that TUBA4A, the gene encoding the Tubulin Alpha 4A protein, is associated with familial amyotrophic lateral sclerosis (ALS).
Stem cell therapies are being hailed as a potential cure for many major health conditions, but there is much still to learn about the highly complex environments needed to optimize these therapies, according to new research.
Researchers have identified an unusual process by which the body can sense the presence of pathogenic bacteria and destroy them. Rather than detect the microbes directly, individual cells monitor how the bacteria interfere with the functioning of energy-producing cellular structures called mitochondria.
