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 ...

Vascular grafts: Technology success or technology failure?

Blood vessel replacements (vascular grafts) are used today for hemodialysis blood access, trauma repair and cardiovascular reconstruction. The first synthetic vascular grafts (blood vessel replacements) were developed just ...

Neuroscience

New ultrafast fMRI technique may help inform brain stimulation

Brain stimulation, such as deep brain stimulation (DBS), is a powerful way to treat neurological and psychiatric disorders. While it has provided therapeutic benefit for sufferers of Parkinson's, Alzheimer's and addiction ...

New spray fights infections and antibiotic resistance

The World Health Organization (WHO) ranks antibiotic resistance as one of the top ten threats to global health. There is therefore a great need for new solutions to tackle resistant bacteria and reduce the use of antibiotics. ...

Research team closer to 3D printing life-like organs

A team of University of Colorado researchers has developed a new strategy for transforming medical images, such as CT or MRI scans, into incredibly detailed 3D models on the computer. The advance marks an important step toward ...

Rapid tests help make hepatitis C diagnosis easier, study finds

A new study has shown the benefit of using a quick clinic-based diagnostic test for hepatitis C virus (HCV) infection over a standard laboratory-based test. The findings from the study has led to World Health Organization ...

New 3D ultrasound may improve accuracy of liver cancer treatment

A simulated study by researchers at Western University and Lawson Health Research Institute has found a new system that uses ultrasound to construct 3D-images could make treatment of liver cancer, using thermal ablation, ...

Neuroscience

Portable cap can measure cognition with pulsed laser light

Measuring activity in the human brain remains one of the greatest challenges in science and medicine. Despite recent technological advances in areas such as imaging and nanoscience, researchers still struggle to accurately ...

Parkinson's & Movement disorders

Using AI analysis of voice data to detect Parkinson's disease earlier

More than 10 million people worldwide are living with Parkinson's disease. There is no cure, but if symptoms are noticed early, the disease can be controlled. As Parkinson's disease progresses, along with other symptoms speech ...

New tool uses ultrasound 'tornado' to break down blood clots

Researchers have developed a new tool and technique that uses "vortex ultrasound"—a sort of ultrasonic tornado—to break down blood clots in the brain. The new approach worked more quickly than existing techniques to eliminate ...
