How Stem Cells Choose their Careers

“What do you want to be when you grow up?” is a question it seems like every child gets asked. A few precocious ones might answer “a doctor” or “an astronaut,” but most will probably smile and shrug their shoulders. But well before a child could comprehend the question or the concept of choosing one’s […]

PRESERVING BRAIN TISSUE WITH STEM CELLS

Individuals with traumatic brain injuries, or TBIs, frequently experience the shrinking or atrophying of brain tissue near where the injury occurred, causing additional damage beyond the original harm. If this can be prevented, many could function in the future who cannot now. Few therapies currently exist to treat TBIs, but studies suggest that cell-based, or […]

Stem cells can repair Parkinson’s-damaged circuits in mouse brains

The mature brain is infamously bad at repairing itself following damage like that caused by trauma or strokes, or from degenerative diseases like Parkinson’s. Stem cells, which are endlessly adaptable, have offered the promise of better neural repair. But the brain’s precisely tuned complexity has stymied the development of clinical treatments. In a new study […]

Hydroacoustic 3D snapshots of fish habitats could help stem overfishing

Researchers are hoping fishing nets scanned by high resolution sonar, underwater cameras and unmanned aquatic vehicles can help paint one of the most accurate assessments of current fish stocks to date – a key challenge in preventing exploitation of our marine ecosystems. ‘Fishers typically operate huge structures, like enormous nets, which are underwater where they […]

Faster, more efficient energy storage could stem from holistic study of layered materials

A team led by the Department of Energy’s Oak Ridge National Laboratory developed a novel, integrated approach to track energy-transporting ions within an ultra-thin material, which could unlock its energy storage potential leading toward faster charging, longer-lasting devices. Charged ions, shown in green, move into ultra-thin layers of energy storage materials, shown as blue and […]

Heart attack damage reduced by shielded stem cells

Bioengineers and surgeons from Rice University and Baylor College of Medicine (BCM) have shown that shielding stem cells with a novel biomaterial improve the cells’ ability to heal heart injuries caused by heart attacks. In a study using rodents, a team led by Rice’s Omid Veiseh and Baylor’s Ravi Ghanta showed it could make capsules of wound-healing mesenchymal […]
