Amputee Grasps Objects With LifeHand
Grasping with suitable pressure, without damaging or dropping
objects - people do this all the time. Researchers have now mastered
artificially reproducing this sequence with the LifeHand 2.

Face Mask Can
Diagnose COVID-19
The wFDCF face mask can
detect the presence of the
SARS-CoV-2 virus in a patient's
breath. The button-activated
mask gives results within 90
minutes.

Robot-Assisted
Dressing
Robot-assisted dressing can aid
those with disabilities or limited
mobility, but it must be done
safely. Researchers from MIT have
introduced an algorithm to do
just that.

Mapping Neural
Networks
Rice University engineers are
analyzing hydra to learn how
they sense touch, a step toward
understanding neural networks
in all living creatures.

A steerable catheter allows surgeons to deliver therapies, in this case
platinum coils that block blood flow to an aneurysm, in the deepest recess
of the brain. (Credit: UCSD)
should include; where these should be placed; and the
amount of hydraulic pressure needed to actuate it. To guide
the catheter, the surgeon compresses a handheld controller
to pass saline fluid into the tip to steer it. Saline is used to protect
the patient; if the device should fail, then saline harmlessly
enters the bloodstream. The catheter's steerable tip is
visible on x-rays.
" This technology is ideal for situations when I need to make a
180 degree turn from the catheter position in the parent artery,
and maintaining position and reducing kick-out is critical, " says
Dr. David Santiago-Dieppa, neurosurgeon at UC San Diego
Health. " This advance may ultimately allow us to treat
aneurysms, other brain pathologies, and even strokes that we
haven't been able to in the past. "
The work is poised to make a significant difference in the way
aneurysm surgery is conducted, physicians say.
" This type of precision can be realized with steerable tools,
and the successful deployment of these tools should move us
forward in permitting improved access, decreased procedural
time, better capacity utilization, decreased radiation exposure,
and other related and expected benefits, " says Dr.
Alexander Norbash, chair of the department of radiology at
UC San Diego Health.
The next steps include a statistically significant number of animal
trials and first-in-human trials.
The work was funded by the American Heart Association, the
American-Australian Association Sir Keith Murdoch Scholarship,
UC San Diego's Galvanizing Engineering in Medicine program,
the Chancellor's Research Excellence Scholarship, and the
National Institutes of Health.
