Our Brains Keep Us 15 Seconds ‘in The Past’ to Help Us See a Stable World, Says Study
Posted by Genevieve Klien in category: neuroscience
Our eyes are continuously bombarded by an enormous amount of visual information – millions of shapes, colors, and ever-changing motion all around us.
For the brain, this is no easy feat.

The Future Of Medicine: Fighting Deadly Diseases With Smart Devices And Digital Biomarkers
Posted by Gemechu Taye in categories: biotech/medical, genetics, health, mobile phones, neuroscience
What are biomarkers? They are medical signals that can measure health in an accurate and reproducible way. Common examples include blood pressure readings, heart rate, and even genetic test results.
Modern digital devices measure several health parameters. Fitbit trackers use sensors such as accelerometers to tell how many steps we’ve taken in a day or how fast we’ve been walking. When can such novel health measures function as medical biomarkers?

Neuroscience research suggests a shared mechanism underlies both sleep disturbance and mental disorders
Posted by Genevieve Klien in categories: biotech/medical, neuroscience, nuclear energy
New research published in Human Brain Mapping provides evidence of a shared neural mechanism that underlies sleep disturbance and mental disorders in preadolescents. The findings indicate that sleep disturbance and mental health problems are both related to the connectivity between and within two important brain networks.
“I noticed the importance of sleep years ago when I read several papers about the immediate amyloid protein deposition in the brain after short-term sleep deprivation. Amyloid is neurotoxic waste in the brain and needs to be transported out by cerebrospinal fluid,” said study author Ze Wang, an associate professor of diagnostic radiology and nuclear medicine at the University of Maryland School of Medicine.
“But cerebrospinal fluid is basically static most of the time. The best time to have more cerebrospinal fluid and increased flow rate is at night when you lay down and fall asleep. It is this time that our cerebral blood flow reduces. Because our brain has a fixed size, the reduction of cerebral blood flow creates space for cerebrospinal fluid and the inhomogeneous change of blood flow creates power for cerebrospinal fluid to flow and then transport the neural waste out. This is why our brain generates two times as much cerebrospinal fluid at night than daytime.”

Factory Defect IC Revived With Sandpaper And Microsoldering
Posted by Shubham Ghosh Roy in categories: biotech/medical, computing, engineering, neuroscience
We might be amidst a chip shortage, but if you enjoy reverse-engineering, there’s never a shortage of intriguing old chips to dig into – and the 2513N 5×7 character ROM is one such chip. Amidst a long thread probing a few of these (Twitter, ThreadReader link), [TubeTime] has realized that two address lines were shorted inside of the package. A Twitter dopamine-fueled quest for truth has led them to try their hand at making the chip work anyway. Trying to clear the short with an external PSU led to a bond wire popping instead, as evidenced by the ESD diode connection disappearing.
A dozen minutes of sandpaper work resulted in the bare die exposed, making quick work of the bond wires as a side effect. Apparently, having the bond pads a bit too close has resulted in a factory defect where two of the pads merged together. No wonder the PSU wouldn’t take that on! Some X-acto work later, the short was cleared. But without the bond wires, how would [TubeTime] connect to it? This is where the work pictured comes in. Soldering to the remains of the bond wires has proven to be fruitful, reviving the chip enough to continue investigating, even if, it appears, it was never functional to begin with. The thread continued on with comparing ROMs from a few different chips [TubeTime] had on hand and inferences on what could’ve happened that led to this IC going out in the wild.
Such soldering experiments are always fun to try and pull off! We rarely see soldering on such a small scale, as thankfully, it’s not always needed, but it’s a joy to witness when someone does IC or PCB microsurgery to fix factory defects that render our devices inoperable before they were even shipped. Each time that a fellow hacker dares to grind the IC epoxy layers down and save a game console or an unidentified complex board, the world gets a little brighter. And if you aren’t forced to do it for repair reasons, you can always try it in an attempt to build the smallest NES in existence!
