Blockchains work like DNA, says a new study. Its instructions are replicated across thousands of “nodes,” much as DNA is replicated in cells.
Northwestern Medicine investigators have discovered that a subset of proteins in mitochondria of brain and heart cells are long-lived, supporting the long-term stability of mitochondrial complex architecture.
The study, published in the Journal of Cell Biology, was led by Jeffrey Savas, PhD, assistant professor in the Ken & Ruth Davee Department of Neurology’s Division of Behavioral Neurology, of Medicine the in Division of Nephrology and Hypertension, and of Pharmacology.
Previous work led by Savas discovered that nuclear pore complex proteins in post-mitotic neurons are exceptionally long-lived and persist for months in mouse and rat brains. These proteins, termed long-lived proteins, or LLPs, provide long-term stability and structure to the nuclear pore and subsequently to the nuclear envelope of neurons; however, this concept had never been considered for other intracellular organelles, until now.

Sharp wave-ripples from the hippocampus are shown to modulate peripheral glucose homeostasis in rats, offering insights into the mechanism that links sleep disruption and blood glucose regulation in type 2 diabetes.
Deploying two unrelated CRISPR nucleases in tandem, with multiplexed CRISPR RNAs and a chemically stabilized activator, creates a simple, one-step assay that can rapidly detect attomolar concentrations of RNA without needing target amplification.
Val Kilmer lost his voice due to throat cancer. Now, through AI technology, he has it back.
He can now use technology to replicate his voice. Video in the article below.
Economists have learned that new technological breakthroughs usually don’t cause a jump in productivity right away. The technology needs time to marinate so companies can test how best to deploy it in their industry. Brynjolfsson argues artificial intelligence and machine learning have now simmered long enough to make a dramatic difference. Others are not as convinced.
Rapid adoption of robots and artificial intelligence during the pandemic combined with a rebound in government investment is making some economists optimistic about a return of a 1990s economy with widespread benefits.
Summary: Researchers discuss different current neural network models and consider the steps that need to be taken to make them more realistic, and thus more useful, as possible.

Neuroscience is a field most obviously associated with medicine and/or psychology. However, my background in physics and computer science enables me to explore, and further understand, how the brain computes and stores information, identifying the underlying physical mechanisms and the interplay between them.
As the disease swept the globe and scientists deployed tools such as polymerase chain reaction tests to detect the novel coronavirus in people, a team of researchers at the University of Pennsylvania’s School of Veterinary Medicine worked to determine if dogs could also be trained to find infections.
The proof-of-concept study, published in April in the journal PLOS ONE, showed that the virus has an odor that trained dogs can identify in urine and saliva. Now, the researchers—with the help of Tuuka, Griz, Toby, Rico, and Roxie—are examining whether canines can sniff out coronavirus’ scent in sweaty T-shirts.
If the dogs can accurately detect it on clothing, they could patrol places such as airports and stadiums to sniff out the virus in public settings.
After examining past disease eradications, a new scientific paper argues that the global eradication of COVID-19 is still a genuine possibility.
