‘Machine Scientists’ Distill the Laws of Physics From Raw Data

Posted by in categories: biotech/medical, food, genetics, information science, robotics/AI

The latest “machine scientist” algorithms can take in data on dark matter, dividing cells, turbulence, and other situations too complicated for humans to understand and provide an equation capturing the essence of what’s going on.


Despite rediscovering Kepler’s third law and other textbook classics, BACON remained something of a curiosity in an era of limited computing power. Researchers still had to analyze most data sets by hand, or eventually with Excel-like software that found the best fit for a simple data set when given a specific class of equation. The notion that an algorithm could find the correct model for describing any data set lay dormant until 2009, when Lipson and Michael Schmidt, roboticists then at Cornell University, developed an algorithm called Eureqa.

Their main goal had been to build a machine that could boil down expansive data sets with column after column of variables to an equation involving the few variables that actually matter. “The equation might end up having four variables, but you don’t know in advance which ones,” Lipson said. “You throw at it everything and the kitchen sink. Maybe the weather is important. Maybe the number of dentists per square mile is important.”

Longevity Research is an Economic Necessity

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

It is vital to recognize the immediate economic importance of i nvesting in longevity and healthy-aging sciences.

Aging itself is a complex series of at least 300 biological processes involving more than 10% of our genetic makeup. It follows that methods to combat these effects must be a combination of sciences, from biotech to biophysics and pharmaceuticals. There is no single “silver bullet” solution.

Aging, along with the physical and mental decay that accompanies it, is still widely regarded as a natural and inevitable thing. It is not, it is a degenerative disease in which the physical integrity and structure of our cells decay each time they divide to replace old ones or as part of any healing process.

Scientists engineer a bacteria to produce a drug used to treat Parkinson’s disease

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

The results of the study could lead to new treatment options. In a groundbreaking new study published in the journal Nature on Thursday, researchers have compared the brain cells of patients who had died from either Parkinson’s disease or dementia to people unaffected by the disorders and found which brain cells are responsible for both conditions.


A team of researchers has created a bacteria that can produce a steady and consistent source of medicine inside a patient’s gut, suggesting the possibility for genetically edited bacteria to be an efficient Parkinson’s disease treatment.

Lab-Grown Brain Experiment Reverses The Effects of Autism-Linked Gene

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

Scientists have uncovered changes in neurological structure that could underlie the autism spectrum disorder known as Pitt Hopkins syndrome, thanks to the help of lab-grown brains developed from human cells.

Furthermore, the researchers were able to recover lost genetic functions through the use of two different gene therapy strategies – hinting at the possibility of treatments that could one day give those with the condition new options in improving their quality of life.

Pitt Hopkins syndrome is a neurodevelopmental condition stemming from a mutation in a DNA-management gene called transcription factor 4 (TCF4). Classed on the autism spectrum on account of its severe impact on motor skills and sensory integration, it’s a complex condition that presents with a range of severities.

Could the blueprint for life have been generated in asteroids?

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

Using new analyses, scientists have just found the last two of the five informational units of DNA and RNA that had yet to be discovered in samples from meteorites. While it is unlikely that DNA could be formed in a meteorite, this discovery demonstrates that these genetic parts are available for delivery and could have contributed to the development of the instructional molecules on early Earth. The discovery, by an international team with NASA researchers, gives more evidence that chemical reactions in asteroids can make some of life’s ingredients, which could have been delivered to ancient Earth by meteorite impacts or perhaps the infall of dust.

All DNA and RNA, which contains the instructions to build and operate every living being on Earth, contains five informational components, called nucleobases. Until now, scientists scouring had only found three of the five. However, a recent analysis by a team of scientists led by Associate Professor Yasuhiro Oba of Hokkaido University, Hokkaido, Japan, identified the final two nucleobases that have eluded scientists.

Nucleobases belong to classes of organic molecules called purines and pyrimidines, which have a wide variety. However, it remains a mystery why more types haven’t been discovered in meteorites so far.

Dr Katcher’s E5 Experiment May 2022 Update | Review

Posted by in categories: biotech/medical, genetics, life extension

Not an amazing update. All female rats are not getting the results the previous group of males got. To my knowledge human trials are still actively being set up for late this year.


In this video we report on the May 2022 update from Dr. Katcher’s experiment with E5, where he is testing to see how long the rats will stay alive if they are given an E5 injection every 90 days.

Identifying the wide diversity of extraterrestrial purine and pyrimidine nucleobases in carbonaceous meteorites

Posted by in categories: biotech/medical, genetics

All DNA/RNA nucleobases were identified in carbonaceous meteorites. Having been provided to the early Earth as a component in carbonaceous meteorites, these molecules might have played a role for the emergence of genetic functions in early life.

Researchers find a genetic cause for lupus

Posted by in categories: biotech/medical, genetics

😀



A team of international researchers have identified a genetic cause of lupus. Researchers of the study pinpointed that DNA mutations in a gene that senses viral RNA represents one cause of the chronic condition, affecting approximately 1 in 1,000 people living in the UK. It is important to note that this genetic cause is not the sole trigger for everyone affected by lupus.

Researchers of the study sequenced the whole DNA genome of a juvenile systemic lupus erythematosus (JSLE) patient called Gabriela, who was diagnosed with severe lupus at the age of seven. A severe case such as this, with early onset of symptoms, is a rarity and is commonly associated with a single genetic cause, unlike adult-onset lupus.

YouthBio CEO: The time is right to develop epigenetic reprogramming therapies

Posted by in categories: biotech/medical, genetics, life extension

Earlier this month, we brought you the news that epigenetic reprogramming startup YouthBio Therapeutics had emerged from stealth. The company shed some light on its plans to develop epigenetic reprogramming therapies for age-related diseases by rejuvenating certain cells in our bodies. YouthBio aims to achieve this rejuvenation by developing gene therapies that enable partial cellular reprogramming – an area of longevity science that is now attracting significant commercial interest.

Longevity. Technology: Cellular reprogramming refers to the process of returning adult cells to a “pluripotent” state: blank, embryonic-like cells that can become any cell in the body. This reprogramming can be achieved using techniques based on the discovery of Yamanaka factors.
