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 ...

Surgery

How close are we to developing pig-to-human organ transplants?

In a new article published Oct. 13 in the journal Science, Megan Sykes, the Michael J. Friedlander Professor of Medicine and professor of microbiology and immunology and surgical sciences (in surgery) and director of Columbia's ...

Can smartphones predict mortality risk?

Passive smartphone monitoring of people's walking activity can be used to construct population-level models of health and mortality risk, according to a new study publishing October 20 in the open access journal PLOS Digital ...

Neuroscience

Engineers record neurons to pinpoint synaptic links

It's a mystery how human thoughts and dreams emerge from electrical pulses in the brain's estimated 100 trillion synapses, and Rice University neuroengineer Chong Xie dreams of changing that by creating a system that can ...
