How head injuries lead to serious brain diseases

Biologists reveal the hidden molecular basis of brain disorders and provide the first cell atlas of the hippocampus -- the part of the brain that helps regulate learning and memory -- as it is affected by traumatic brain injury. The[…]

Gut hormone and brown fat interact to tell the brain it's time to stop eating

Researchers have shown that so-called 'brown fat' interacts with the gut hormone secretin in mice to relay nutritional signals about fullness to the brain during a meal. The study bolsters our understanding of a long-suspected role of brown adipose tissue[…]

Brain, muscle cells found lurking in kidney organoids grown in lab

New research has identified rogue cells -- namely brain and muscle cells -- lurking within kidney organoids. Such cells make up only 10 to 20 percent of an organoid's cells, but their presence indicates that the 'recipes' used to coax[…]

Scorpion venom to shuttle drugs into the brain

Biologists have described the capacity of a small protein (a peptide) derived from chlorotoxin, found in scorpion venom (Giant Yellow Israeli scorpion), to carry drugs across the blood-brain barrier (BBB).

How exercise could help fight drug addiction

The siren call of addictive drugs can be hard to resist, and returning to the environment where drugs were previously taken can make resistance that much harder. However, addicts who exercise appear to be less vulnerable to the impact of[…]

Pain can be a self-fulfilling prophecy

A new brain imaging study of 34 people found that when people expect to feel intense pain, they do, even if they aren't subjected to painful stimuli. Surprisingly, these false expectations can persist even when reality demonstrates otherwise, the study[…]

New methods to identify Alzheimer's drug candidates with anti-aging properties

Old age is the greatest risk factor for many diseases, including Alzheimer's disease (AD) and cancer. Geroprotectors are a recently identified class of anti-aging compounds. New research has now identified a unique subclass of these compounds, dubbed geroneuroprotectors (GNPs), which[…]

Autism behaviors show unique brain network fingerprints in infants

A new study has identified unique functional brain networks associated with characteristic behaviors of autism spectrum disorder (ASD) in 12- and 24-month old children at risk for developing ASD.

The illusion of multitasking boosts performance

Our ability to do things well suffers when we try to complete several tasks at once, but a series of experiments suggests that merely believing that we're multitasking may boost our performance by making us more engaged in the tasks[…]

Cognitive decline -- radiation -- brain tumor prevented by temporarily shutting down immune response

Scientists report the first animal model of glioma -- the most aggressive and most common form of brain cancer in the US -- that can also be used to study the long-term effects of radiation therapy in tumor-bearing brains. Using[…]

Dynamic audiovisuals increase spectator attention, but inhibits conscious processing

According to a new study, scene changes diminish a spectator's blink rate, producing an increase in attention. The results of the study demonstrate that a dynamic and chaotic audiovisual editing causes more activity in the visual processing areas, while continuous[…]

New insights into the aging brain

A group of scientists investigated why the choroid plexus contains so much more klotho than other brain regions.They showed that klotho functions as a gatekeeper that shields the brain from the peripheral immune system.

New clues to the origin and progression of multiple sclerosis

Mapping of a certain group of cells, known as oligodendrocytes, in the central nervous system of a mouse model of multiple sclerosis (MS), shows that they might have a significant role in the development of the disease. The discovery can[…]

Decrease in specific gene 'silencing' molecules linked with pediatric brain tumors

Experimenting with lab-grown brain cancer cells, researchers have added to evidence that a shortage of specific tiny molecules that silence certain genes is linked to the development and growth of pediatric brain tumors known as low-grade gliomas.
