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.

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 ...

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 ...

Heart attack on a chip shows how heart changes after the event

Researchers at the University of Southern California Alfred E. Mann Department of Biomedical Engineering have developed a "heart attack on a chip," a device that could one day serve as a testbed to develop new heart drugs ...

Neuroscience

Using light to manipulate neuron excitability

Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific neurons and how they ...

Medications

Wearable sensor could guide precision drug dosing

For some of the powerful drugs used to fight infection and cancer, there's only a small difference between a healing dose and a dose that's large enough to cause dangerous side effects. But predicting that margin is a persistent ...

Runners gain no advantage from compression stockings: Study

Compression stockings are popular among runners, but there is no scientific evidence that they actually enhance exercise performance. On the contrary, muscle oxygenation in the stocking wearer's lower leg during running is ...

Machine learning diagnoses pneumonia by listening to coughs

Pneumonia is one of the world's leading causes of death and affects over a million people a year in the United States. The disease disproportionately impacts children, older adults, and hospitalized patients. To give them ...

The feces thesis: Using machine learning to detect diarrhea

Cholera, a bacterial disease that induces diarrhea, affects millions of people and results in about 150,000 deaths each year. Identifying potential communal disease spread for such an outbreak would alert health professionals ...
