While most parents of preschool and elementary aged children strive to give their children a balanced, nutritional diet, some of their strategies to promote healthy eating may backfire, a national poll suggests.

A specific protein, TP53INP2, might prevent muscle loss associated with aging. A new study indicates that high levels of this protein are linked to greater muscle strength and healthier aging. This discovery paves the way for new treatments that could enhance the quality of life for the elderly.

Middle-aged and older adults believe that old age begins later in life than their peers did decades ago, according to a new study.

Clarifying the cause of a skin disease led to the discovery of a new disease-causing gene, a new category of diseases, and new perspectives for both counseling and therapy. The discovery is the first time that epigenetic silencing, the 'switching off' of an otherwise intact gene, has been recognized as the cause for a skin disease.

Researchers have developed a new shoe insole technology that helps reduce the risk of diabetic foot ulcers, a dangerous open sore that can lead to hospitalization and leg, foot or toe amputations.

When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes' role in epileptic seizures, finding that that astrocyte activity starts approximately 20 seconds before the onset of epileptic neuronal hyperactivity.

Toxic chemicals used to flame-proof plastic materials can be absorbed into the body through skin, via contact with microplastics, new research shows.

Dietary treatment is more effective than medications in irritable bowel syndrome (IBS). With dietary adjustments, more than seven out of ten patients had significantly reduced symptoms.

In a discovery that could hasten treatment for patients with multiple sclerosis (MS), scientists have discovered a harbinger in the blood of some people who later went on to develop the disease.

Although there are still some aspects pending confirmation for its use in the clinical setting, and its resolution needs to be improved slightly, a study has shown that a method routinely used to carry out ophthalmological tests can also be used to monitor the neurodegeneration that occurs in Parkinson's patients. In the course of the research it was found that the neurodegeneration of the retina probably precedes cognitive impairment.

The first health impact study of coal train pollution centers on the San Francisco Bay Area, with scientists finding communities near passing coal trains suffer worse health outcomes.

The annual influenza vaccine has become less effective on average over time. One reason may be reduced vaccine efficacy in people with obesity than those with a healthier body mass index (BMI), while the number of people with high BMI grows. Findings showed switching mice to a healthy diet four weeks before influenza vaccination protected 100% from a later flu exposure, despite still having a high BMI.

A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain's neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. Researchers now report how neuronal networks in the mouse brain are fine-tuned.

In posttraumatic stress disorder (PTSD), intrusive thoughts, changes in mood, and other symptoms after exposure to trauma can greatly impact a person's quality of life. About 6 percent of people who experience trauma develop the disorder, but scientists don't yet understand the neurobiology underlying PTSD. Now, a new genetic study of more than 1.2 million people has pinpointed 95 loci, or locations in the genome, that are associated with risk of developing PTSD, including 80 that had not been previously identified.

Monitoring and treating a case of multiple sclerosis requires reliable and long-term data on how the disease is progressing in the person in question. Fitness trackers and smartphones can supply this data, as a research team has now shown.

Two siblings who have the only known mutations in a key gene anywhere in the world have helped scientists gain new insights that could help progress the search for new treatments in type 1 diabetes.

Thought emerges and is controlled in the brain via the rhythmically and spatially coordinated activity of millions of neurons, scientists argue in a new article. Understanding cognition and its disorders requires studying it at that level.

Scientists created four cannabis-derived CBN analogs (chemical look-a-likes) with enhanced neuroprotective properties and potential for therapeutic application in neurological disorders like Alzheimer's, Parkinson's, and traumatic brain injury. Their findings reveal novel aspects of CBN's neuroprotective activity and demonstrate the clinical potential of CBN and value of studying its analogs.

In the long history of recommendations for nutritional intake, current research is trending toward the concept of 'food as medicine' -- a philosophy in which food and nutrition are positioned within interventions to support health and wellness.
