Neuroscience

DNA molecules with 'invisibility cloak' sequences can selectively target diseased cells in motor neuron disease

Researchers at the Francis Crick Institute and the UCL Queen Square Institute of Neurology have developed DNA molecules which contain "invisibility cloak" sequences, preventing healthy cells from reading the messages they ...

Immunology

Gut bacteria engineered to act as tumor GPS for immunotherapies

Immunotherapeutic approaches have substantially improved the treatment of patients with advanced malignancies. However, most advanced and metastatic malignancies remain incurable and therefore represent a major unmet need.

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 ...

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, ...

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 ...

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 ...

Neuroscience

New open-source app for precise brain mapping

The hippocampus is a small, complex, folded brain structure that holds clues to several brain disorders. It is also one of the most difficult-to-map regions of the brain. After developing a successful technique to digitally ...

Nasal injections could treat long-term COVID-19–related smell loss

Early in the pandemic, when people with COVID-19 began reporting that they lost their sense of smell, Zara Patel, MD, figured as much. A professor of otolaryngology at Stanford Medicine, Patel has, for years, studied loss ...

UAVs to deliver first aid drugs to emergency patients quickly

For patients suffering from sudden illnesses such as myocardial infarction and severe hypoglycemia, prompt administration of emergency medications is imperative, otherwise they may be at great risk of death. Actually, a large ...

Neuroscience

Brain-computer-leg interface restores motion after stroke

Skoltech researchers have devised a novel method for leg rehabilitation after injury or stroke that uses a brain-computer interface and electrical stimulation of the spine delivered through the skin. Created by scientists ...

New technique to detect extremely small numbers of virus cells

Annual vaccinations against seasonal flu have become a way to protect the elderly and vulnerable in society, but the development of new flu vaccines is both expensive and time-consuming. There is therefore a great need for ...
