Canada and Australia curb predatory stem cell market: Researchers hope to replicate success in US

Over the last decade, a number of U.S. clinics have marketed stem cell products directly to consumers as purported treatments for a host of diseases and injuries. The problem is that many of these interventions have scant ...

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 ...

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 ...

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 ...

Blood-based 'liquid biopsy' might spot early-stage cancers

An experimental blood test may be able to catch a dozen different types of cancer with a high degree of accuracy—including some that are particularly tricky to detect, a preliminary study suggests.

Healing the unhealable: New approach helps bones mend themselves

Young babies and newborn mice can naturally heal damage to the bones that form the top of the skull, but this ability is lost in adults. In a new study published in Proceedings of the National Academy of Sciences, University ...

New tool to study hepatitis B could open the door to a cure

Hepatitis C and hepatitis B viruses both attack the liver, eventually causing deadly cirrhosis or cancer. But while antivirals can cure 95% of HCV infections, its cousin HBV has long eluded effective therapeutics. As a result, ...

Immunology

Less painful, more convenient antibody treatments

Antibody treatments exist for many diseases, but require injections or IV infusions, which are painful, inconvenient and carry risks. Now, a team of researchers at the University of Connecticut has created a way to deliver ...

The promise—and pitfalls—of medical AI headed our way

A patient is lying on the operating table as the surgical team reaches an impasse. They can't find the intestinal rupture. A surgeon asks aloud, "Check whether we missed a view of any intestinal section in the visual feed ...
