A new study gives insight into the relationship between depression and dementia. The current study, which involved 1,764 people from the Religious Orders Study and the Rush Memory and Aging Project, indicates that the association of depression with dementia is independent of dementia-related brain changes.
Exposure of pregnant mice to the pesticide DDT is linked to an increased risk of obesity, diabetes, high cholesterol, and related conditions in female offspring later in life, according to a study led by the University of California, Davis.
Researchers have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their technique allows zooming in and out on views of brain activity within mice, and it enabled the team to watch brain cells light up as mice “called” to each other.
In what is believed to be the largest genetic analysis of what triggers and propels progression of tumor growth in a common childhood blood cancer, researchers report that they have identified a possible new drug target for treating the disease.
The brains of children with autism are relatively inflexible at switching from rest to task performance, according to a new study. Instead of changing to accommodate a job, connectivity in key brain networks of autistic children looks similar to connectivity in the resting brain. And the greater this inflexibility, the more severe the child’s manifestations of repetitive and restrictive behaviors that characterize autism, the study found.
University of Washington bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV. Their method spins the drug into silk-like fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials such as gels or creams.
Young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases, according to research from the Brown School at Washington University in St. Louis.
Researchers have found that children with sensory processing disorders have decreased structural brain connections in specific sensory regions different than those in autism, further establishing SPD as a clinically important neurodevelopmental disorder.
Just as no two people possess the same genetic makeup, a recent study has shown that no two single tumor cells in breast cancer patients have an identical genome.
The best way to cure most cases of cancer is to surgically remove the tumor. The Achilles heel of this approach, however, is that the surgeon may fail to extract the entire tumor, leading to a local recurrence. With a new technique, researchers at the University of Pennsylvania have established a new strategy to help surgeons see the entire tumor in the patient, increasing the likelihood of a positive outcome.
A new study indicates that middle-aged adults with a history of problem drinking are more than twice as likely to suffer from severe memory impairment in later life.
Stop sunbathing and using indoor tanning beds, the acting U.S. surgeon general warned in a report released Tuesday that cites an alarming 200 percent jump in deadly melanoma cases since 1973.
When cancers spread into the bloodstream, they often take on different characteristics, requiring different therapies. But it is hard to find these rare blood-borne cells. So, relapsed patients often do not get personalized care. Now, researchers have come up with a solution that zeros in on elusive circulating tumor cells (CTCs).
Researchers have found a missing link that helps to explain how ALS, one of the world’s most feared diseases, paralyses and ultimately kills its victims. The breakthrough is helping them trace a path to a treatment or even a cure.
Individuals with major depressive disorder or bipolar disorder who receive low-field magnetic stimulation (LFMS) show immediate and substantial mood improvement, researchers report.
When you're expecting something— like the meal you've ordered at a restaurant— or when or when something captures your interest, unique electrical rhythms called gamma oscillations sweep through your brain. New research shows that little known supportive cells in the brain known as astrocytes may in fact be major players that control these waves.
Researchers have identified a mechanism that overrides the cells’ warning signals, enabling cancers to continue to divide even without a robust blood supply.
Bioengineers have designed a peptide structure that can stop the harmful changes of the body’s normal proteins into a state that’s linked to widespread diseases such as Alzheimer’s, Parkinson’s, heart disease, Type 2 diabetes and Lou Gehrig’s disease.
U.S. health officials are monitoring the Ebola outbreak in Africa but say the risk of the deadly germ spreading to the United States is remote. The Centers for Disease Control on Monday sent a health alert to U.S. doctors about the outbreak.
A new research project shows that many adolescents suffer from knee pain for several years. The pain impacts both sporting activities and quality of life.
Using data from over 18,000 patients, scientists have identified more than two dozen genetic risk factors involved in Parkinson’s disease, including six that had not been previously reported.
In a massive effort to catalog the molecular causes of stomach cancer, scientists have identified four subtypes of tumors based on shared mutations and other molecular abnormalities.
Microorganisms can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal drugs. Now, a new study has shown that microorganisms can use a temporary silencing of drug targets to gain the benefits of drug resistance without the commitment.
A new study has found that turning the thermostat down a few notches at night may expand brown fat tissue mass and activity, which could lead to metabolic benefits such as more effective disposal of glucose.
Nigerian health authorities raced to stop the spread of Ebola on Saturday after a man sick with one of the world's deadliest diseases brought it by plane to Lagos, Africa's largest city with 21 million people.
