Microrobot Developed for Delivery of Stem Cells to the Brain

Researchers from Daegu Gyeongbuk Institute of Science and Technology (DGIST) in South Korea have developed a new microrobot that can precisely deliver therapeutic cells to very specific parts of the brain. Their work, recently published in Science Robotics, demonstrates that neural stem cells can be cultured and differentiated on their robot and th (Read more...)

Researchers Trip People to Improve Prosthetic Legs

People using prosthetic legs have to be constantly vigilant about potential obstacles in their way. That is because if they stumble, there’s a pretty good chance that they’ll suffer a fall. Prosthetic legs, even powered ones, don’t have the capacity to recover from a stumble, as this is a very challenging task for a mechanical [&h (Read more...)

Electric Brain Stimulation Shown to Improve Memory Function

Our memories often seem ephemeral, coming and going without any obvious reasons. Researchers at UCLA seem to have come up with a way to bring some memories back that would probably otherwise have gone missing forever. The team relied on transcranial direct current stimulation (tDCS), a technology that can direct low energy electricity into specific (Read more...)

New Microfluidic Chip to Accurately Model Blood-Brain Barrier

Researchers from the Wyss Institute at Harvard University have developed a new microfluidic lab-on-a-chip device that aims to more accurately model the complex biological properties of the blood-brain barrier (BBB). Their work, recently published in Nature Communications, demonstrates the device is able to mimic the highly selective drug and antibo (Read more...)

New AI Tool, HeadXNet, to Help Detect Brain Aneurysms

Researchers from Stanford University have developed a new AI tool, dubbed HeadXNet that detects brain aneurysms from computed tomographic angiography (CTA) scans. Their work, recently published in JAMA Network Open, demonstrates that their AI tool helped radiologists identify 6 more scans with aneurysm for every 100 scans already diagnosed with ane (Read more...)

Scientists Develop Accurate Model of Blood-Brain Barrier

The blood-brain barrier (BBB) is the primary reason that so few medicines exist to treat brain conditions. Drugs that can attack tumors elsewhere usually can’t penetrate the defenses of the BBB, so figuring out how to get through it is important for the development of future drugs and other therapies. There have been attempts to […]

Transcranial Magnetic Stimulation Improves Working Memory

Researchers from Duke University School of Medicine have found that magnetic brain stimulation can help improve working memory. They studied repetitive transcranial magnetic stimulation (rTMS), showing that it improved memory task performance in all ages of adults. Given that individuals with Alzheimer’s will more than double by 2050, rTMS ma (Read more...)

Microscopic Graphene Flakes to Stop Epileptic Seizures

During epileptic seizures, the brain’s excitatory neurons go haywire, generating extreme amounts of electric activity. There are already electronic devices available that help to prevent and mitigate seizures, but so far they’re only effective in some patients while having all the downsides of a serious implantation. A team of European (Read more...)
