Digital Journal: Air pollution linked to cognitive decline

A new study has drawn a connection between levels of air pollution and cognitive decline. This is of a major societal concern, given that the majority of the world’s population live in areas that exceed WHO pollution recommendations.According to the World Health Organization, 91 percent of the world’s population lived in areas where pollution is […]

Futurity: These neurons could be key to fighting addiction

Researchers have discovered a correlation between the number of neurons that produce orexin—a chemical messenger important for sleep and appetite—and addiction, according to a new study with cocaine-addicted rats.Restoring the number of orexin neurons to normal, or blocking orexin signaling in the brain, made the rats no longer addicted, suggesting the increased orexin neurons is […]

Healthline: Smokers have a higher risk of developing dementia

Does smoking raise your risk of memory problems later in life? A new study conducted by researchers at Seoul National University Hospital in South Korea suggests that it does. The researchers followed more than 46,000 men, ages 60 and older, from 2006 to 2013. They found that men who had never smoked and those who […]

TIME: Scientists are developing new ways to treat disease with cells, not drugs

When Nichelle Obar learned she was pregnant with her second child last year, she never expected that her pregnancy, or her baby, would make history. But when the 40-year-old food-and-beverage coordinator from Hawaii and her fiancé Christopher Constantino went to their 18-week ultrasound, they learned something was wrong. The heart was larger than it should […]

UPI: Study: ALS affects brain’s cognition skills

The minds of patients suffering from amyotrophic lateral sclerosis (ALS) are damaged by the disease, despite the longstanding belief that this was not the case, a new study reveals. In fact, in the later stages of ALS, also called Lou Gehrig’s disease, patients experience a decline in their thinking and language skills, researchers report. (September […]

Medical Xpress: Malicious brain cell identified—surprising finding fills gap in understanding astrocytes’ role in brain disease

Astrocytes—the star-shaped cells of our brain—are very busy. Their job description includes maintaining the blood-brain barrier, removing excess neurotransmitters, repairing brain tissue and more. Their important role in brain function suggests astrocytes are also involved in disease. Scientists are particularly interested in uncovering how they may drive inflammation in the brain. Brain inflammation is linked […]

Phys.org: Enhanced 3-D imaging poised to advance treatments for brain diseases

Researchers have developed a combination of commercially available hardware and open-source software, named PySight, which improves rapid 2-D and 3-D imaging of the brain and other tissues. By seamlessly enabling integration of the fastest 3-D imaging solution available today, the advance in microscopy could help scientists to better understand brain dynamics and discover new treatments […]

Scientific American: Brain’s dumped DNA may lead to stress, depression

Humans and other mammals react to stressful situations through a series of well-orchestrated evolutionary adaptations. When faced with a predator looking for its next meal, or with worry of losing a job, our bodies release a cascade of stress hormones. Our heart rate spikes, breath quickens, muscles tense up and beads of sweat appear. (September […]

Science Daily: Blood and brain fluid change first in Huntington’s disease

A simple blood test can detect the earliest changes caused by Huntington’s disease, even before scans can pick up any signs in the brain, a new UCL-led study has found.The study, published today in Science Translational Medicine, builds on recent evidence by the same research team, which found that a novel blood test can predict […]

UPI: Whole grain foods could help prevent type 2 diabetes

It may seem counterintuitive, but eating bread, pasta and cereal may actually help prevent type 2 diabetes, as long as those foods are made from whole grains, new research suggests.The study found that each serving of whole-grain foods per day was linked to as much as an 11 percent drop in the risk of type […]
