Centuries of study have yielded many theories about how the brain gives rise to human intelligence. Some think it arises from a single region or neural network. Others argue that metabolism is key. A new paper makes the case that the brain's dynamic properties -- how it is wired but also how that wiring shifts in response to changing intellectual demands -- are the best predictors of intelligence in the human brain.
In the fight against brain damage caused by stroke, researchers have turned to an unlikely source of inspiration: hibernating ground squirrels. While the animals' brains experience dramatically reduced blood flow during hibernation, just like human patients after a certain type of stroke, the squirrels emerge from their extended naps suffering no ill effects. Now, a team of NIH-funded scientists has identified a potential drug that could grant the same resilience to stroke patients.
Slight changes to the system for allocating deceased-donor kidneys could result in higher rates of organ procurement and lead to more kidney transplants across the country, according to new research co-authored by an Indiana University Kelley School of Business professor.
Using a simple 'mirror trick' and not-so-simple computational analysis, scientists affiliated with the Marine Biological Laboratory (MBL) have considerably improved the speed, efficiency, and resolution of a light-sheet microscope, with broad applications for enhanced imaging of live cells and embryos.
A new University of Washington study points to yet another human factor that is hampering the ability of fish to reproduce: the timing of our fishing seasons. The study considers how the timing of fishing efforts might disproportionately target certain fish and change the life history patterns of entire populations.
Stink-flirting among ring-tailed lemurs come at a cost, but may also influence females in choosing a mate.
In a new longitudinal observational study, scientists at Beth Israel Deaconess Medical Center (BIDMC) looked at the relationships among maternal snoring, childhood snoring and children's metabolic characteristics -- including body mass index (BMI) and insulin resistance, which reflects future risk for developing diabetes and cardiovascular disease -- in approximately 1,100 children followed from gestation through early adolescence.
A University of Toronto student and professor have teamed up to discover that Britain's increasing cloudiness during the summer could be an important reason for the mysterious increase in rickets among British children over the past few decades.
Alzheimer's disease (AD) is known to cause memory loss and cognitive decline, but other functions of the brain can remain intact. The reasons cells in some brain regions degenerate while others are protected is largely unknown. In a paper to be published in Stem Cell Reports, researchers from Brigham and Women's Hospital have found that factors encoded in the DNA of brain cells contribute to the patterns of degeneration, or vulnerability, in AD.
Gut bacteria at a young age can contribute to multiple sclerosis disease onset and progression.
