Researchers have programmed an MRI scanner to simultaneously monitor magnetized particles while propelling them through blood vessels as a means to locally deliver drugs. Existing approaches combine the magnetic force from an MRI scanner with the force produced by particle collisions. But traditionally, it’s challenging to image using the MRI scanner and propel the particles […]
Researchers at the Massachusetts Institute of Technology and Boston Children’s Hospital said today they developed a system that can take convert an MRI scan of a heart into a 3-D printed model. The printed hearts can be used to give surgeons a hands-on, tangible model of the heart they will be operating on before they touch a […]
By Erin Horan Hypoplastic left heart syndrome (HLHS) is a rare but serious form of congenital heart disease that leaves the left pumping chamber (ventricle) of the heart severely underdeveloped. Children born with HLHS can’t pump enough oxygenated blood from their heart to the rest of their body and need surgery as soon as possible to […]
By David Altman Hospitals are among the most hazardous workplaces in the U.S. In 2011, according to the Occupational Safety and Health Administration, 253,700 accidents were reported, an average of 6.8 work-related injuries for every 100 full-time employees. Rates of injuries reported to OSHA are decreasing in all industries except for hospitals, whose rates are […]
By Nancy Fliesler MRI is a staple of surgical imaging, but it has the potential to do much more than take pictures. In 2011, bioengineer Pierre Dupont, PhD, and colleagues demonstrated that an MRI machine’s magnetic field could power a motor strong enough to control a robotic instrument, in this case driving a needle into an organ […]
By Nancy Fliesler More than 70 different genes are known to cause deafness when mutated. Jeffrey Holt, PhD, envisions a day when patients with hearing loss have their genome sequenced and their hearing restored by gene therapy. A proof-of-principle study published today by the journal Science Translational Medicine takes a clear step in that direction, restoring hearing in […]
(Reuters) — Gene therapy for deafness is moving closer to reality, with new research yesterday showing the technique for fixing faulty DNA can improve responses in mice with genetic hearing loss. Separately, a clinical trial backed by Novartis (NYSE:NVS) is under way to help a different group of people who have lost their hearing through […]
By Nancy Fliesler If you have children present, you might want to click out of this post. But if you want to understand motivation, you’ll want to know about the sexual behavior of fruit flies. In the brain, motivational states are nature’s way of matching our behaviors to our needs and priorities. But motivation can […]

One of the immune system’s basic jobs is to tell “self” from “non-self.” Our cells carry markers that the immune system uses to recognize them as being part of us. Cells that don’t carry those markers – like bacteria and other pathogens – therefore don’t belong.
