Harnessing Chaos to Secure Devices

 Seems a quite clever idea.  A means of securing devices.

A new version of physically unclonable functions (PUFs) developed by a research team led by The Ohio State University (OSU) could prevent even the most sophisticated hackers from accessing electronic devices. The team's method leverages small manufacturing variations in computer chips—sometimes visible only at the atomic level—to create PUFs that could be used in secure ID cards, supply chain tracking, and authentication applications. Using these tiny variations, researchers can create unique sequences of 0s and 1s, dubbed "secrets." The researchers calculated one of their PUFs could create 1077 secrets. OSU's Daniel Gauthier said that if a hacker could guess one secret every microsecond, or 1 million secrets per second, it would take about 20 billion years to guess all the secrets in one microchip. Verilock's Jim Northup said, "This novel approach to a strong PUF could prove to be virtually un-hackable." .... ' 

Deep Learning Searches for Covid-19 Treatments

Treatments using deep learning, based on human gene interactions with drugs.

Computer Model Makes Strides in Search for Covid-19 Treatments

Ohio State News, Emily Caldwell, February 1, 2021

A deep learning computer model developed by Ohio State University (OSU) computer scientists to predict human genes' interaction with drugs has identified at least 10 compounds as potential Covid-19 treatments. The DeepCE model taps the L1000 repository of human cell-line data concerning how gene expression changes in response to medications, and the DrugBank dataset on chemical structures and other details of roughly 11,000 approved and investigational drugs. The investigators applied DeepCE's gene expression prediction matrix to the genetic data in early Covid-19 papers and additional government information. Said OSU's Ping Zhang, "We can predict gene expression values for new chemicals not from one cell to one cell, but automatically predict the role of a drug on different cell lines and different genes."

Bio-Ink for 3D Printing Inside the Body

Quite a remarkable possibility when linked to medical robotics.

Researchers at The Ohio State University (OSU) have developed a bio-ink that can be three-dimensionally (3D) printed at human body temperature, and solidified using visible light. Bio-inks are composed of living cells suspended in a gel and are safe for use inside people, potentially paving the way for 3D printing inside the body. Using a 3D printing nozzle affixed to robotic machinery to dispense bio-ink in a controlled manner, the researchers were able to bio-print onto soft materials, with interlocking knobs left beneath the surface anchoring the printed structure to the body like surgical staples. OSU's David Hoelzle said the goal is not to bio-print an entire organ, but to "augment a standard surgery by delivering a biomaterial with a tethered growth factor to jumpstart healing, or a tethered drug to prevent infection. ... We envision a biomaterial bio-ink printing tool as another tool in the surgeon's toolset."  ... ' 

Brain Pacemaker

Is something that can be described as a 'brain pacemaker' a viable idea?  Brains are very different from hearts.   From my connection to Ideaconnection.  With video.

Brain Pacemaker Could Treat Alzheimer's
An innovative brain pacemaker could offer treatment for the effects of Alzheimer’s disease.

Being investigated by a team from Ohio State University, the system relies on deep brain stimulation (DBS) to deliver mild electrical stimulation to the frontal regions of the brain. According to neurosurgeon Ali Rezai, who is conducting the clinical trials, the procedure “holds promise for improving connectivity, cognitive and functional performance, and should be further studied in Alzheimer's disease."   ...
