Mike West on human cellular reprograming and rejuvenation (con S/T en Español)

Posted by in categories: biotech/medical, life extension

Excerpt from an interview made by James Ruhle, founder at Simple Biotech, to Michael (Mike) West, founder and CEO of AgeX Therapeutics.

During this 4 minute excerpt, Mike explains in a nutshell the work he and his team at AgeX are doing “to reverse the aging of cells and tissues in the body in the truest and fullest sense of the work”, and clarifies the reasons why it doesn’t mean to convert and adult into a child.

Raspberry Pi system can detect viruses on other devices without use of software

Posted by in categories: biotech/medical, computing, mobile phones, security

A team of researchers at the Institute of Computer Science and Random Systems has built a non-software-based virus detection system using a Raspberry Pi, an H-field probe and an oscilloscope to detect electromagnetic wave signatures of multiple types of viruses. The team presented its system and test results at last month’s ACM Machinery’s Annual Computer Security Applications Conference and published a paper describing their system on ACM’s Research Article page.

The idea behind the new system is that running software generates electromagnetic waves. And each piece of software generates its own unique wave patterns due to the way the software executes its code. The researchers took advantage of this knowledge and began using an H-field probe to capture wave patterns of known computer viruses running on various devices and viewed the results on an oscilloscope. They saw oscilloscope patterns that were unique to individual viruses as they were running. The researchers used that information to program a Raspberry Pi to identify data from the other two devices to recognize known virus wave patterns, using the system as a virus detector. To determine if a virus is running on a computer, IoT device or smartphone, a user places the H-field probe close enough to the device to read the electromagnetic waves that are generated. The Raspberry Pi then reports on whether it found any viruses, and if so, which ones.

Scientists uncover new information about cellular death process, previously thought to be irreversible

Posted by in categories: biotech/medical, chemistry, engineering, genetics

A study published by researchers at the University of Illinois Chicago describes a new method for analyzing pyroptosis–the process of cell death that is usually caused by infections and results in excess inflammation in the body–and shows that process, long thought to be irreversible once initiated, can in fact be halted and controlled.

The discovery, which is reported in Nature Communications, means that scientists have a new way to study diseases that are related to malfunctioning cell death processes, like some cancers, and infections that can be complicated by out-of-control inflammation caused by the process. These infections include sepsis, for example, and acute respiratory distress syndrome, which is among the major complications of COVID-19 illness.

Pyroptosis is a series of biochemical reactions that uses gasdermin, a protein, to open large pores in the cell membrane and destabilize the cell. To understand more about this process, the UIC researchers designed an “optogenetic” gasdermin by genetically engineering the protein to respond to light.

Powerful New Superpower Molecule Could Revolutionize Science

When scientists discovered DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Remember IBM’s Amazing Watson AI? Now It’s Desperately Trying to Sell It Off

Posted by in categories: biotech/medical, government, health, robotics/AI

In fact, it’s not even the first time that IBM has tried — unsuccessfully — to unload the project, in yet another sign that corporate expectations for AI are continuing to crash into reality.

“Health care always is going to turn out to be more subtle, as well as more regulated for the right reasons, than it is in other areas,” IBM CEO Arvind Krishna said in an Axios and HBO interview last year. “And to me, that’s natural. It is a decision that may impact somebody’s life or death. You got to be more careful. So in health care, it turns out maybe we were too optimistic.”

The sale, if it actually goes through this time, would affect millions of patients and entire government healthcare strategies.

First Reversal of Type 1 Diabetes Using Precision Medicine

Posted by in categories: biotech/medical, genetics, health

Houston, TX — Oct 8, 2020 - In a letter published today in the New England Journal of Medicine, a team of physicians from Baylor College of Medicine, Texas Children’s Hospital, and the University of California, San Francisco, describe a remarkable case of a Type 1 diabetes (T1D) patient, who no longer needs insulin to maintain optimal blood sugar levels. The physicians employed a precision/personalized medicine approach to specifically target the underlying genetic mutation, which was the primary driver of this patient’s diabetes.

“To the best of our knowledge, this is the first example of a T1D patient who has experienced a complete reversal of insulin-dependence and we are excited by the prospect that that could be a viable therapeutic strategy for a subset of T1D patients” said corresponding author Dr. Lisa R. Forbes, deputy director for clinical services and community outreach for the Texas Children’s William T. Shearer Center for Human Immunobiology and assistant professor of Pediatrics, Immunology, Allergy and Retrovirology at Baylor.

T1D is a chronic condition in which the pancreas produces little to no insulin, a hormone that maintains sugar levels in the blood. Currently, the treatment options available to T1D patients consist of managing blood sugar levels with insulin, diet and exercise to prevent further complications.

University of Maryland School of Medicine Faculty Scientists and Clinicians Perform Historic First Successful Transplant of Porcine Heart into Adult Human with End-Stage Heart Disease

Posted by in categories: biotech/medical, robotics/AI

Researchers at the Indian Institute of Technology Bhubaneswar, in collaboration with TCS Research and Wageningen University, recently devised a new strategy that could improve coordination among different robots tackling complex missions as a team. This strategy, introduced in a paper pre-published on arXiv, is based on a split-architecture that addresses communication and computations separately, while periodically coordinating the two to achieve optimal results.
