These findings indicate that liver cell repair and tissue regeneration are occurring.
The liver is known for its ability to regenerate. It can completely regrow itself even after two-thirds of its mass has been surgically removed. But damage from medications, alcohol abuse or obesity can eventually cause the liver to fail. Currently, the only effective treatment for end-stage liver disease is transplantation.
However, there is a dearth of organs available for transplantation.

But what if, instead of liver transplantation, there were a drug that could help the liver regenerate itself?
SpaceX’s 25th cargo resupply mission to the International Space Station (ISS) launched from Pad 39A on July 15, 2022. The Cargo Dragon carried up to 13,000 lbs of scientific payload and tech, including 8 Cubesats. The capsule docked with the ISS on July 16, 2022.
The Dragon Capsule carried out a variety of experiments that are designed to help scientists understand more about the world around us. The scientific research performed in the microgravity aboard the ISS can’t be replicated anywhere else. Consider the ISS like an orbital laboratory, performing science for the Earth — off the Earth.
These experiments include studies of the immune system, including how it responds to stress and medications.
In 1906, Alois Alzheimer, a psychiatrist and neuroanatomist, reported “a peculiar severe disease process of the cerebral cortex” to a gathering of psychiatrists in Tübingen, Germany. The case was a 50-year-old woman who suffered from memory loss, delusions, hallucinations, aggression and confusion – all of which worsened until her untimely death five years later.
O.o!!!.
Johns Hopkins researchers say that an experimental anticancer compound appears to have reversed behaviors associated with schizophrenia and restored some lost brain cell function in adolescent mice with a rodent version of the devastating mental illness.
The drug is one of a class of compounds known as PAK inhibitors, which have been shown in animal experiments to confer some protection from brain damage due to Fragile X syndrome, an inherited disease in humans marked by mental retardation. There also is some evidence, experts say, suggesting PAK inhibitors could be used to treat Alzheimer’s disease. And because the PAK protein itself can initiate cancer and cell growth, PAK inhibitors have also been tested for cancer.
In the new Johns Hopkins-led study, reported online March 31 in the Proceedings of the National Academy of Sciences, the researchers found that the compound, called FRAX486, appears to halt an out-of-control biological “pruning” process in the schizophrenic brain during which important neural connections are unnecessarily destroyed.

To demonstrate this, researchers stored historic audio recordings on these molecules for the first time and then retrieved them with 100 percent accuracy. The experiment showed that DNA not only offers a place to save a dense package of information in a tiny space, but because it can last for hundreds of years, it reduces the risk that it will go out of date or degrade in the way that cassette tapes, compact discs, and even computer hard drives can.
“DNA is intrinsically and exquisitely a stable molecule,” Emily Leproust, CEO of the biotech firm Twist Bioscience, which works on DNA synthesis, told Seeker. Her company collaborated with Microsoft, the University of Washington, and the Montreux Jazz Digital Project on the DNA data feat.
The two performances they stored and retrieved, “Smoke on the Water” by Deep Purple and “Tutu” by Miles Davis, are the first DNA-saved files to be added to UNESCO’s Memory of the World Archive, a collection of audio and visual pieces of cultural significance. Both were performed at the Montreux Jazz Festival, an annual event in Switzerland.

Since the time of Hippocrates and Herophilus, scientists have placed the location of the mind, emotions and intelligence in the brain. For centuries, this theory was explored through anatomical dissection, as the early neuroscientists named and proposed functions for the various sections of this unusual organ. It wasn’t until the late 19th century that Camillo Golgi and Santiago Ramón y Cajal developed the methods to look deeper into the brain, using a silver stain to detect the long, stringy cells now known as neurons and their connections, called synapses.
Today, neuroanatomy involves the most powerful microscopes and computers on the planet. Viewing synapses, which are only nanometers in length, requires an electron microscope imaging a slice of brain thousands of times thinner than a sheet of paper. To map an entire human brain would require 300,000 of these images, and even reconstructing a small three-dimensional brain region from these snapshots requires roughly the same supercomputing power it takes to run an astronomy simulation of the universe.
Fortunately, both of these resources exist at Argonne, where, in 2015, Kasthuri was the first neuroscientist ever hired by the U.S. Department of Energy laboratory. Peter Littlewood, the former director of Argonne who brought him in, recognized that connectome research was going to be one of the great big data challenges of the coming decades, one that UChicago and Argonne were perfectly poised to tackle.

A new device developed at The Ohio State University can start healing organs in a “fraction of a second,” researchers say.
The technology, known as Tissue Nanotransfection (TNT), has the potential to save the lives of car crash victims and even deployed soldiers injured on site. It’s a dime-sized silicone chip that “injects genetic code into skin cells, turning those skin cells into other types of cells required for treating diseased conditions,” according to a release.
In lab tests, one touch of TNT completely repaired injured legs of mice over three weeks by turning skin cells into vascular cells.
