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 ...

Cardiology

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 ...

Surgery

AI generated content helps in 3D brain reconstruction

Minimally invasive surgery and automated robot-guided surgery are likely to be performed under extreme conditions, which require new demands on intraoperative information acquisition capabilities. Three-dimensional (3D) brain ...

Capsule captures first look inside digestion in healthy people

Using a specially designed capsule, researchers can now voyage through the digestive system, collecting new data about digestion and microorganisms. The work by a team including researchers at the University of California, ...

Neuroscience

Deployable electrodes for minimally invasive craniosurgery

Stephanie Lacour's specialty is the development of flexible electrodes that adapt to a moving body, providing more reliable connections with the nervous system. Her work is inherently interdisciplinary.

Genetics

Scientists release a new human 'pangenome' reference

Researchers have released a new high-quality collection of reference human genome sequences that captures substantially more diversity from different human populations than what was previously available. The work was led ...
