Computer Vision, Deep Learning Aid Prosthetic Hands

A built-in camera and artificial intelligence can improve the speed and grasping ability of a prosthetic hand, as shown in tests with people missing a hand. Test results and a description of the technology developed by engineers at Newcastle University in the U.K. appear in yesterday's issue of the Journal of Neural Engineering.

Nanoparticles Boost T-Cells to Fight Leukemia

A cancer research lab designed a process to treat leukemia by reprogramming cells in the immune system with genes on nanoscale biodegradable particles. The team from Fred Hutchinson Cancer Research Center in Seattle describes its discovery and tests with lab mice in yesterday’s issue of the journal Nature Nanotechnology.

Crispr-Based Diagnostics System Designed

A bioengineering team from Harvard University and Massachusetts Institute of Technology designed simple, inexpensive diagnostics tools to detect infectious diseases, based on Crispr, an emerging genome-editing technology. A report of the technology appears in this week’s issue of the journal Science.

Computer Model Devised to Predict Drug Side Effects | Science and Enterprise

A systems biology lab at UC-San Diego developed a prototype computer model combining genomics and red blood cell metabolism that can test for potential side effects of drugs from an individual’s blood sample.

Delivery Technique Devised to Cross Blood-Brain Barrier | Science and Enterprise

Medical researchers developed a technique that allows drugs for treating neurological disorders to penetrate the blood-brain barrier, a difficult obstacle up to now. The technique adapts an ear, nose and throat surgical procedure to help drugs overcome this obstacle.

Virus Particles Rebuilt to Boost Immunotherapies | Science and Enterprise

Engineers at Stanford University redesigned a hepatitis virus from the inside out to make it a better vehicle to stimulate the immune system for treating disease. The team had to rewrite the DNA in the genetic material carried in the core of the virus to produce the desired solution. By editing the genetic code sequence in the virus’s core, they were able to assemble a virus particle that would be invisible to the immune system, yet stronger, and still behave like a virus.

3-D Printed Guide Devised to Regrow Nerve Fibers | Science and Enterprise

Researchers from medical and engineering faculties at five universities in the U.S. developed a technique combining three-dimensional printing with tissue regeneration to grow new peripheral nerves in lab rats. The researchers say the proof-of-concept study advances nerve regeneration technology by customizing the design of a replacement part with computational modeling, as well as integrating biochemical functions into the production of that new part.

Alliance Mounts Comprehensive ALS Research Program | Science and Enterprise

A coalition of three medical centers in the U.S. is leading a comprehensive research initiative to find treatments and eventually cures for amyotrophic lateral sclerosis, or ALS. The collaboration, known as Answer ALS, plans to amass a coordinated knowledge base about ALS across a range of disciplines, and make their findings freely available to colleagues worldwide to speed development of therapies.
