Vanderbilt University’s Warren Center for Neuroscience Drug Discovery has entered into an exclusive worldwide licensing and collaboration agreement with San Diego-based ACADIA Pharmaceuticals Inc., which will seek to develop and commercialize treatments for central nervous system disorders, such as Alzheimer’s disease and schizophrenia. This collaboration will focus on positive allosteric modulators (PAMs) of […]

A neuroscientist’s neon pink arm cast led him and fellow researchers at Washington University School of Medicine in St. Louis to discover previously undetected neuronal pulses in the human brain that activate after an immobilizing illness or injury. The pulses appeared on MRI scans used to measure the brain activity […]

A new study by researchers at UCSF Benioff Children’s Hospitals and St. Jude Children’s Research Hospital have identified what they believe to be a key reason behind patients’ treatment-resistance in the rare inflammatory disorder HLH. The finding could offer additional insights into other immune conditions, including a type of childhood […]

Research from the Department of Kinesiology at McMaster University has found that the practical advantages of high-intensity interval training (HIIT), or short bursts of all-out exercise, could be especially beneficial for people who have experienced spinal cord injuries (SCI). While many studies have proven the benefits of HIIT for the […]

A Rice University lab’s project to make better fluorescent tags has turned into a method to kill tumors. Switching one atom in the tag does the trick. Rice chemist Han Xiao and his colleagues found that replacing a single oxygen atom with a sulfur atom in a common fluorophore turns it into a photosensitizing molecule. When […]

Like finding that needle in the haystack every time, your T cells manage what seems like an improbable task: quickly finding a few invaders among the many imposters in your body to trigger its immune response. T cells have to react fast and do so nearly perfectly to protect people from diseases. […]

The brain and its surrounding blood vessels exist in a close relationship. The vessels supply the energy-hungry neuronal cells with nutrients. Researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now discovered how cells of the blood vessels sense the metabolic condition of the brain and […]

A world-first study of the epigenetics of posttraumatic growth and resilience points the way for further research into how people can overcome the negative impacts of trauma after events such as bushfires, serious motor vehicle accidents, domestic violence, childhood and work-related trauma. QUT trauma researcher Professor Jane Shakespeare-Finch from the […]

MIT researchers pinpoint mechanism and demonstrate that drugs could help. By developing a lab-engineered model of the human blood-brain barrier (BBB), neuroscientists at MIT’s Picower Institute for Learning and Memory have discovered how the most common Alzheimer’s disease risk gene causes amyloid protein plaques to disrupt the brain’s vasculature and […]

Scientists have discovered an important cell signaling pathway in the kidney which if stopped, could hold the key to treating chronic kidney disease as well as other deadly conditions, including heart attack and stroke. The pathway was already known to exist in the brain, where it helps to maintain the […]

Our brains use various reference frames—also known as coordinate systems—to represent the motion of objects in a scene. Some coordinate systems are more useful than others for representing information. To represent a location on Earth, for example, we might use an Earth-centered coordinate system such as latitude and longitude. In […]

We owe a great deal to the hair cells in our inner ear—without them we couldn’t detect sounds or take five steps without tripping. Moreover, these cells happen to be a useful model for biologists who want to understand how tissues self-organize into complex shapes during embryonic development. The cells’ […]

Researchers found that efforts should be focused on optimizing embryo culture to ensure healthy outcomes for mothers and offspring. An experimental study from researchers in the Perelman School of Medicine at the University of Pennsylvania links a specific procedure – embryo culture – that is part of the assisted reproduction […]

The U.S. Food and Drug Administration has approved the first video game therapeutic as a treatment for attention deficit hyperactivity disorder (ADHD) in children, based on research by UC San Francisco’s Adam Gazzaley, MD, PhD.

In 2005, the University of California, Berkeley, researchers made the surprising discovery that making conjoined twins out of young and old mice — such that they share blood and organs — can rejuvenate tissues and reverse the signs of aging in the old mice. The finding sparked a flurry of research […]

Senescent cells accumulate throughout the body with age. They are constantly created and destroyed throughout life, but the balance between creation and destruction is upset with age, leading to an accumulated burden of cellular senescence. These cells secrete a potent mix of signals that produce chronic inflammation, disrupt tissue structure and cell function, and encourage […]

The formation of stress granules in cells is an interesting topic. As the name might suggest, this behavior emerges in cells undergoing stress, such as lack of nutrients, heat, cold, and so forth. Stress granules are transient structures that form within cells, made up of a wide variety of biomolecules that are packed […]

Many aspects of aging correlate with one another, even those with quite different underlying mechanisms and proximate causes. The various forms of root cause damage that result in the aging process, as well as their downstream consequences, all interact with one another. So whether or not any specific correlation teaches us anything […]
