Scientists report that newly formed brain cells in the mouse olfactory system— the area that processes smells— play a critical role in maintaining proper connections.
For many patients diagnosed with diabetes, treating the disease can mean a burdensome and uncomfortable lifelong routine of monitoring blood sugar levels and injecting the insulin that their bodies don't naturally produce. Now, tiny biosensors are being developed that could one day eliminate the need for these manual blood sugar tests.
The World Health Organization called the Ebola outbreak "the most severe, acute health emergency seen in modern times" on Monday but also said that economic disruptions can be curbed if people are adequately informed to prevent irrational moves to dodge infection.
A breach of infection control resulting in a Dallas health worker getting Ebola raises fresh questions about whether hospitals truly can safely take care of people with the deadly virus, as health officials insist is possible.
People with autism spectrum disorder often experience a period of accelerated brain growth after birth. No one knows why, or whether the change is linked to any specific behavioral changes. A new mouse study demonstrates how inflammation can trigger an excessive division of neural stem cells that can cause “overgrowth” in offspring’s brain.
Researchers have established how two degenerative diseases that present in similar ways are in fact quite different. Progressive Supranuclear palsy (PSP) and Parkinson’s disease (PD) have overlapping symptoms but remain difficult to distinguish.
A previously unknown mechanism through which the brain produces new nerve cells after a stroke has been discovered. The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain.
In rare cases, patients with allergies to metals develop persistent skin rashes after metal devices are implanted near the skin. New research suggests these patients may be at increased risk of an unusual and aggressive form of skin cancer.
Scientists have discovered a new class of molecules– produced in human and mouse fat– that protects against diabetes. The researchers found that giving this new fat to mice with the equivalent of type 2 diabetes lowered their elevated blood sugar.
The first study of a possible Ebola vaccine is underway in Africa: University of Maryland researchers say three health care workers in Mali received the experimental shots.
Fad diets come and go, but might there be something to the ones that involve consuming grapefruit and grapefruit juice? New research suggests that a closer look at grapefruit juice is warranted.
Researchers have identified a set of RNA molecules that are detectable in tissue samples and urine of prostate cancer patients, but not in normal healthy individuals.
Ebola, as with many emerging infections, is likely to have arisen due to man’s interaction with wild animals and eating wild meat known as bushmeat. A new survey of people across southern Ghana aims to find out what drives consumption of bat bushmeat, and how people perceive the risks associated with the practice.
Even before he lost his right hand to an industrial accident four years ago, Igor Spetic had family open his medicine bottles. Cotton balls give him goose bumps. Now, blindfolded during an experiment, he feels his arm hairs raise when a researcher brushes the back of his prosthetic hand with a cotton ball.
Autism is characterized by many different symptoms: difficulty interacting with others, repetitive behaviors, and hypersensitivity to sound and other stimuli. Neuroscientists have put forth a new hypothesis that accounts for these behaviors and may provide a neurological foundation for many of the disparate features of the disorder.
A new form of gene therapy for boys with X-linked severe combined immunodeficiency syndrome (SCID-X1), a life-threatening condition also known as “bubble boy” disease, appears to be both effective and safe, according to new research.
An experimental drug saved the lives of 16 of 16 monkeys with the Marburg virus, a killer near-indistinguishable from Ebola, which caused the death of a Ugandan health worker Oct. 6.
The death of the first Ebola patient diagnosed in the United States renewed questions about his medical care and whether Thomas Eric Duncan's life could have been extended or saved if the Texas hospital where he first sought help had taken him in sooner.
A Ugandan health worker recently died of Marburg, a highly infectious disease that manifests as a viral hemorrhagic fever, Uganda's Ministry of Health confirmed Monday as health workers moved to quarantine a total of 80 people who had been in contact with the victim.
The first Ebola patient diagnosed in the United States died in a Dallas hospital Wednesday, a little more than a week after his diagnosis exposed gaps in the nation's defenses against the disease and set off a scramble to track down anyone exposed to him.
Studying rats as model subjects, scientists found that adolescents were at an increased risk of suffering negative health effects from sugar-sweetened beverage consumption.
When kids say “the darnedest things,” it’s often in response to something they heard or saw. Now researchers found that children as young as 15 months can detect anger when watching other people’s social interactions and then use that emotional information to guide their own behavior.
A magnetic resonance imaging (MRI) technique can detect signs of cognitive decline in the brain even before symptoms appear, according to a new study. The technique has the potential to serve as a biomarker in very early diagnosis of preclinical dementia.
A team of engineers has successfully developed a three-dimensional-printed device, which mimics the operation of the liver to remove dangerous toxins from the blood.
Two Americans and a German scientist won the Nobel Prize in chemistry Wednesday for finding ways to make microscopes more powerful than previously thought possible, allowing scientists to see how diseases develop inside the tiniest cells.
