Dendrites, the branch-like projections of neurons, were once thought to be passive wiring in the brain. But now, researchers have shown that these dendrites do more than relay information from one neuron to the next.
The largest international Alzheimer's disease genetics collaboration to date has found 11 new genetic areas of interest that contribute to late onset Alzheimer's Disease (LOAD).
Hunting for compounds that target the cancer stem cells of the blood cancer acute myeloid leukemia (AML) is now easier thanks to work by a team of scientists who built a new cell culture model that mimics AML in its niche in the bone marrow and makes the search for promising new drugs more effective.
Mice models of Alzheimer's treated with one abdominal injection of an antibody fragment designed by researchers showed, after only five days, improved memory and ability to learn as the result of less aggregated toxins and an increase in the number of neurons.
The considerable diversity of HIV worldwide represents a critical challenge for designing an effective HIV vaccine. Now, a scientific team has shown that bioinformatically optimized HIV vaccine antigens might be useful in the design of a global HIV vaccine.
According to a new study, a novel mammography procedure could generate substantial added-value for the diagnosis of breast cancer in medical practice.
An analysis of the genomes of 12,000 addicts and non-addicts revealed some unexpected risk factors for dependence on opiates, a new study shows.
A novel combination of two oral targeted drugs dramatically slowed the growth of glioblastoma brain tumors in mice and significantly extended the animals’ survival, scientists report.
Stroke is caused by a blood clot blocking a blood vessel in the brain, which leads to interruption of blood flow and shortage of oxygen. Now, a research group has taken an important step towards a treatment for stroke using stem cells.
In the fight to cure human immunodeficiency virus (HIV), researchers have been dealt a blow. A new study shows that the pool of inactive HIV viruses that lingers silently in a patient’s body is larger than expected.
The ankle is often considered an anatomical jumble, and its role in maintaining stability and motion has not been well characterized. Now, researchers have measured the stiffness of the ankle in various directions using a robot called the “Anklebot.”
Researchers have published the most comprehensive review of the benefits and risks of a daily dose of prophylactic aspirin and warn that greater understanding of side effects is needed.
Researchers have, for the first time, taken chimpanzee and bonobo skin cells and turned them into induced pluripotent stem cells (iPSCs), a type of cell that has the ability to form any other cell or tissue in the body.
A new breast cancer risk gene has been discovered which explains the early-onset breast cancer in some multiple-case breast cancer families.
Cancer researchers have deciphered the operating principles of a genetic switch that cancer cells use to decide when to metastasize and invade other parts of the body.
Doctors now have convincing evidence that they put HIV into remission, hopefully for good, in a Mississippi baby born with the AIDS virus— a medical first that is prompting a new look at how hard and fast such cases should be treated.
In a small preliminary study, researchers say a blood test based on detection of epigenetic alterations may reveal the earliest signs of pancreatic cancer, a disease that is nearly always fatal because of its late diagnosis.
Veterinary researchers have helped identify the origin and possible evolution of an emerging swine virus with high mortality rates that has already spread to at least 17 states. They have traced the recent U.S. outbreaks to a strain from the Anhui province in China.
A promising technique for treating human eye disease has proven effective in preclinical studies and may lead to new treatments to prevent blindness, according to new experiments.
Studying spinal fluid from people at risk for Alzheimer’s disease, researchers have found that a gene variation that had not been considered risky actually can increase the chances of developing Alzheimer’s disease when it occurs in tandem with another gene variant known to elevate risk.
New research shows that one of the brain’s fundamental self-protection mechanisms depends on coordinated, finely calibrated teamwork among neurons and non-neural cells knows as glial cells, which until recently were thought to be mere support cells.
Large areas of vinyl flooring in daycares and schools appear to expose children to a group of compounds called phthalates, which have been linked to reproductive and developmental problems, scientists are reporting.
As researchers develop new therapies based on making specific cells to do specific things, getting the right message to the right group of cells at the right time remains a major challenge. Now, researchers have developed a way to deliver a light signal to specific tissues deep within the body.
New study results show that patients with a body mass index (BMI) in the obese range live on average two to three months less after a pancreatic cancer diagnosis when compared with healthy weight patients.
A study of the full genetic code of a common human virus offers a dramatic confirmation of the "out-of-Africa" pattern of human migration, which had previously been documented by anthropologists and studies of the human genome.
