A novel computer algorithm, or set of rules, that accurately predicts the orbits of planets in the solar system could be adapted to better predict and control the behavior of the plasma that fuels fusion facilities designed to harvest on Earth the fusion energy that powers the sun and stars.
A novel computer algorithm, or set of rules, that accurately predicts the orbits of planets in the solar system could be adapted to better predict and control the behavior of the plasma that fuels fusion facilities designed to harvest on Earth the fusion energy that powers the sun and stars.
The algorithm, devised by a scientist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL), applies machine learning, the form of artificial intelligence (AI) that learns from experience, to develop the predictions. “Usually in physics, you make observations, create a theory based on those observations, and then use that theory to predict new observations,” said PPPL physicist Hong Qin, author of a paper detailing the concept in Scientific Reports. “What I’m doing is replacing this process with a type of black box that can produce accurate predictions without using a traditional theory or law.”
Qin (pronounced Chin) created a computer program into which he fed data from past observations of the orbits of Mercury, Venus, Earth, Mars, Jupiter, and the dwarf planet Ceres. This program, along with an additional program known as a “serving algorithm,” then made accurate predictions of the orbits of other planets in the solar system without using Newton’s laws of motion and gravitation. “Essentially, I bypassed all the fundamental ingredients of physics. I go directly from data to data,” Qin said. “There is no law of physics in the middle.”
In the past few years, researchers have turned increasingly to data science techniques to aid problem-solving in organic synthesis.
The SARS-CoV-2 virus mutates fast. That’s a concern because these more transmissible variants of SARS-CoV-2 are now present in the U.S., U.K. and South Africa and other countries, and many people are wondering whether the current vaccines will protect the recipients from the virus. Furthermore, many question whether we will we be able to keep ahead of future variants of SARS-CoV-2, which will certainly arise.
In my laboratory I study the molecular structure of RNA viruses – like the one that causes COVID-19 – and how they replicate and multiply in the host. As the virus infects more people and the pandemic spreads, SARS-CoV-2 continues to evolve. This process of evolution is constant and it allows the virus to sample its environment and select changes that make it grow more efficiently. Thus, it is important to monitor viruses for such new mutations that could make them more deadly, more transmissible or both.
Did you know, getting a bit cold from time to time can help you get fitter, live longer, reduce pain and discomfort and help you concentrate and feel great?
Whether it is cold showers, ice baths, swimming in open water or trying out cryotherapy, enduring the cold is becoming increasingly popular as a way to hack your body as an aid to longevity and a good health span.
And for a good reason.
It effects metabolism, heart rate, blood pressure and many biomarkers.
It improves pain tolerance and levels, your mood and energy levels.
It effects mitochondrial biogenesis and brown fat stores, even beiging previously white adipose tissue.
In fact, there are hardly any systems left untouched.
But it does have side effects as well, especially for those who have health issues, but they also have the most to gain.
If you want to get more detail then check out this video where I go into more depth looking at the subject and discuss the studies that have been done to assess the effects.
Have a great day.
In Cold Showers Pros And Cons — And Other Cold Therapies, I will be looking at the good, and the bad, when it comes to embracing cold therapies from cold water swimming and ice baths, through to cold showers and cryotherapy.

Forever we have held a view that AGING, DISEASE & DEATH is an un-alterable eventuality, those who dared question were ostracised for playing God.
If you choose to look deeper you will surely be amazed. Bowhead whales live for over 200 yrs “Turriptosis Dohnri” is a Jellyfish that lives forever. Can these #genetics traits be replicated in humans? Could the removal of #senescence #cells that accelerates aging be the answer Is it even possible to control or reverse aging? Can we grow old healthily? 150000 die every day & over 100000 of them are caused by aging.
It is true. From its effect on biomarkers such as heat shock proteins and Fox 03, through to real world impacts on cardiovascular health, to improving mood, helping you live longer healthier and reducing your chance of dying before your time. I think we all know saunas are really great for you, but this will give you all the scientific reasons why… Taking it easy and relaxing for half an hour… Is not just wasting your time… Changes today will make tomorrow better. #saunas
I am going to give you the best reasons in the world to sit back and take it easy in a nice warm environment, and to just forget the troubles of the world.
Maybe play some music, or a podcast, or listen to a book, or just meditate, just relax and take it easy.
It is for your own health after all!!

Although no list like this can be definitive, we polled dozens of researchers over the past year to develop a diverse line-up of ten software tools that have had a big impact on the world of science. You can weigh in on our choices at the end of the story.
From Fortran to arXiv.org, these advances in programming and platforms sent biology, climate science and physics into warp speed.
Almost a year ago, we were told by our governments and healthcare professionals that a two-week shutdown of the economy would “flatten the curve.”
The Chinese Coronavirus (COVID-19) hit American shores — officially, anyway, there is significant evidence that it arrived earlier — in late January 2020. The American public was then told that a two-week shutdown of the economy would “flatten the curve,” relieving the pressure on hospital intensive care units and saving lives in the long run.
The average American, including conservatives, being people of good faith, complied, thinking that this was a common-sense measure that would save lives in the wake of a new and mysterious pandemic.

From cryonics to time travel, here are some of the (highly speculative) methods that might someday be used to bring people back to life.
