UMD received $1.16 million for an endowed professorship through a state program created to spur basic and applied research in scientific and technical fields at Maryland colleges and universities. The grant will partially match a $2 million private donation for its Clark Leadership Chair in Neuroscience.
Since its launch in 2013, the BRAIN Initiative has doled out about $1.3 billion in grants to develop tools that map and manipulate the brain. Until now, it has operated with no formal director. But last week, the NIH, which manages the initiative and is a key funder, announced that neurobiologist John Ngai (UC Berkeley), whose lab focuses on the neural underpinnings of the sense of smell, would take the helm starting in March. In this Q&A, Ngai discusses how the initiative is evolving and how he hopes to influence it.
Freezing of gait is a leading cause of falls for patients with Parkinson's disease. Now, a new device provides visual and auditory cues to help patients overcome freezing. Using the device allows people with Parkinson’s to retain their independence and mobility through being able to walk confidently and reduce the fear of freezing, which can enable a person with Parkinson’s to maintain independence and continue exercising. That exercise can also help slow the progression of the disease and improve day-to-day life.
New research has revealed specific types of neurons that control eating behavior. A team used genetic methods to classify and distinguish various types of neurons that are bundled together in the vagus nerve, the conduit connecting the brain with the stomach and intestines that plays a central role in how the body regulates feeding behaviors. The research has important implications for obesity and metabolic disorders, and possibly also for eating disorders such as bulimia and anorexia nervosa.
In a landmark study that analyzed the DNA of more than 35,000 people from around the world, the international Autism Sequencing Consortium (ASC) identified variants in 102 genes associated with increased risk of developing ASD, up from 65 identified previously. Of the 102 genes, 60 had not been previously linked to ASD and 53 appeared to be primarily connected to ASD as opposed to other types of intellectual disability or developmental delay. The hope is that this growing list of genes will point the way to new and more precise ways of treating ASD in all its complexity.
While the early signs of Parkinson's and MSA are similar—disturbances in movement, tremors, impaired speech, etc.—each disease progresses differently and can require distinct a treatment plan. Moreover, both diseases are characterized by deposits of a protein known as alpha-synuclein (aSyn) in the nervous system, which can become corrupted and start to change shape in a process called misfolding. However, new technology can now detect misfolded aSyn aggregates as a way of developing a sensitive biochemical diagnosis specifically for Parkinson's.
In a swift rise to prominence, Jonathan Pruitt drew attention to the small field of behavioral ecology with eye-catching findings about contrasting personalities—meek and aggressive—in social spiders. But in just 2 weeks, the field has turned on its young star. What began with questions about data in one paper has flared into a scandal, with dozens of papers based on his data on spiders and other animals being scrutinized by scores of co-authors. The furor has even earned a Twitter hashtag—#PruittData—where former collaborators and others are discussing how to analyze his results and debating the implications for their field.
The movie of fruit flies seen here may help explain the ancient origins of the “startle response” and other biomechanical aspects of motion. The video shows a footrace between two flies: one zips along at about 25 millimeters per second, while the second clocks in at a mere 15 millimeters per second. What is causing the delay of the second fly is the rapid release of serotonin into its nervous system, which models a startle response. Scientists suspect the release of serotonin activates motor neurons much like an emergency brake, stiffening and locking up the fly’s leg joints.
You might mistake jewel wings for their colorful cousins, dragonflies. However, new research shows that these two predators share something more profound than their appearance. A team of researchers revealed that the neural systems behind jewel wings’ vision are shared with dragonflies, with whom they have a common ancestor that lived before the dinosaurs. But over the eons, this brain wiring has adapted itself in different ways in each creature, enabling radically different hunting strategies.
Insufficient myelination, likely caused by a lack of mature oligodendrocytes (OL), is linked to autism spectrum disorder, according to a study in mice and postmortem human brains. Myelin, the fatty substance that sheaths and insulates the axons of neurons, is responsible for aiding the quick delivery of signals throughout the brain. Too little myelin leaves the cells vulnerable to damage (as with multiple sclerosis), while too much can muddle the message. OL are the cells that control myelination.
Already half of US adults use intelligent virtual assistants. Moreover, many of the makers of intelligent virtual assistants are poised to roll out health care advice, including personalized wellness strategies. But do intelligent virtual assistants provide actionable health support now? Among 70 different help-seeking queries, the assistants returned actionable responses only four times, with the most common response being confusion. The research team notes there is evidence of capacity among the makers of intelligent virtual assistants to build in resources quickly.
This Washington Post feature follows the Dumsch family as they struggle to find a livable situation for a family member diagnosed with schizophrenia. Scientists don’t know exactly what causes schizophrenia. While some of the risk has to do with genetics, most people with schizophrenia don’t have a first-degree relative with the illness. Environmental factors—such as stress, trauma, and maternal malnutrition—can play a role. Evidence also shows that heavy marijuana use is a factor, especially among young people with a history of family psychosis, though this connection is controversial.
The scientific peer review process benefits greatly when the study section reviewers bring not only strong scientific qualifications and expertise, but also a broad range of backgrounds and varying scientific perspectives. Bringing new viewpoints into the process replenishes and refreshes the study section, enhancing the quality of its output. In this story, Noni Byrnes, the Director of NIH Center for Scientific Review (CSR), provides data about scientific review committees and outlines the CSR's efforts to broaden its diversity of expert perspectives.
