Turning brain cells on using the power of light: Researchers refine noninvasive method of bioluminescent optogenetics

University of Rochester researchers have demonstrated a noninvasive method using BL-OG, or bioluminescent optogenetics, that harnesses light to activate neurons in the brain. The ability to regulate brain activation could ...

Stem cell transplants repair macular holes in primate study

Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report October 3 in the journal Stem Cell Reports. After transplantation, the macular holes were closed by continuous filling ...

Neuroscience

Study hints at ways to generate new neurons in old brains

Most neurons in the human brain last a lifetime, and for good reason. Intricate, long-term information is preserved in the complex structural relationships between their synapses. To lose the neurons would be to lose that ...

Diabetes

A new injectable shows promise to prevent and treat hypoglycemia

People with diabetes take insulin to lower high blood sugar. However, if glucose levels plunge too low—from taking too much insulin or not eating enough sugar—people can experience hypoglycemia, which can lead to dizziness, ...

Exploring how melanin influences clinical oxygen measurements

Obtaining accurate clinical measurements is essential for diagnosing and treating a wide range of health conditions. Regrettably, the impact of skin type and pigmentation is not equally considered in the design and calibration ...

Engineering human heart tissue for scientific study

Northwestern Medicine scientists have developed a new way to measure heart contraction and electrical activity in engineered human heart tissues, according to findings published in Science Advances.

Microfluidic chip brings hope for sepsis prognosis and evaluation

A research team led by Associate Professor Yang Ke from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with the First Affiliated Hospital of Anhui Medical University, developed ...

Biomedical technology

Wearable patch can painlessly deliver drugs through the skin

The skin is an appealing route for drug delivery because it allows drugs to go directly to the site where they're needed, which could be useful for wound healing, pain relief, or other medical and cosmetic applications. However, ...

How electricity can heal wounds three times faster

Chronic wounds are a major health problem for diabetic patients and the elderly—in extreme cases they can even lead to amputation. Using electric stimulation, researchers in a project at Chalmers University of Technology, ...

Smartwatches may be key to development of new Parkinson's treatments

New research shows that commercially available smartphones and watches, like the Apple Watch, are able to capture key features of early, untreated Parkinson's disease. These technologies could provide researchers with more ...

Distinguishing real from fake in the age of synthetic images

Amid headlines about artificial intelligence's implications for everything from education to the future of work itself, Abhinav Jha, an assistant professor of biomedical engineering at the McKelvey School of Engineering and ...

Neuroscience

Brain images just got 64 million times sharper

Magnetic resonance imaging (MRI) is how we visualize soft, watery tissue that is hard to image with X-rays. But while an MRI provides good enough resolution to spot a brain tumor, it needs to be a lot sharper to visualize ...

Cardiology

Graphene 'tattoo' treats cardiac arrhythmia with light

Researchers led by Northwestern University and the University of Texas at Austin (UT) have developed the first cardiac implant made from graphene, a two-dimensional super material with ultra-strong, lightweight and conductive ...

AI diagnoses lung disease based on X-rays

Skoltech researchers have trained a neural network to search for lung pathologies on X-ray images and come up with brief verbal descriptions to accompany them. This task is currently performed by physicians, and it takes ...

Neuroscience

Lipid molecules may help get stroke therapies into the brain

To get therapies into the brain after a stroke, researchers are increasingly making use of the blood–brain barrier, which allows only certain molecules to pass from the blood into the brain. In a study published earlier ...
