The aorta is an important blood vessel, to say the least. It’s the body’s main artery, carrying blood from the heart up to the head and down to the other major organs. That’s why aortic aneurysms, or weak spots in the aorta, are so concerning: if they break, the extreme blood loss is often fatal.

Seattle-area biotech startup Aortica is working on a personalized approach to treating aortic aneurysms, specifically complex abdominal aortic aneurysms, which are more tricky to treat. The company has closed just over $1 million out of a $4 million round of insider funding to further develop the treatment, and Aortica CEO and founder Thomas Douthitt told GeekWire the company has commitments to finish the full $4 million round.

If you are not sure why you should support rejuvenation research, or know people who aren’t, this article explains why rejuvenation would be good for you as an individual.

The reasons why rejuvenation would be good for any given individual should be bleeding obvious. However, you’d be surprised how often people think it all boils down to ‘You’d live forever!’—which by the way is not granted and can be a bit of a controversial concept. The real reasons why rejuvenation would be good for you as an individual are the following.

The elderly of today aren’t exactly famous for their good health, nor for their ability to go about their lives easily and without help in even the simplest tasks. Old people have weaker bodies, weaker immune systems, are prey to a number of horrible diseases and chronic pain, and cannot take care of themselves with the same ease as they did when they were young. Pay attention next time you go downtown. You’ll see elderly people walking slowly and with difficulty, perhaps with the aid of a walker or a cane. They can’t hear well and they can’t see well. Climbing the stairs for them feels like more climbing a mountain. A young person can shake off the flu after a few days of discomfort; an old person may well die of the complications of it, because their weak immune system did not do a very good job. This is, in a nutshell, why young people can take care of themselves and old people end up in hospices or have to be watched over by their families.

You don’t have to be a gambler to appreciate the complexities of the card game Texas Hold ‘Em. It involves a strategy that needs to evolve based on the players around the table, it takes a certain amount of intuition, and it doesn’t require the player to win every hand. Just a few days ago, an artificial intelligence (AI) algorithm named Libratus beat four professional poker players at a no-limit Texas Hold ‘Em tournament played out over 20 days.

If you have even the slightest understanding of how to write code, you would realize that it is impossible to actually code a software program to do that with such “imperfect information”. The AI algorithm did exceptionally well and was utilizing strategies that humans had never used before. Professional poker players are in no danger of losing their jobs, but the incredible capabilities of what AI is mastering these days should make everyone wonder just how safe their jobs actually are.

Let’s take the $3 billion medical imaging market. It’s no secret that AI is now performing certain medical imaging tasks better than human doctors. Pundits say “well, people will always trust a human doctor over an AI” and the answer we’d have to that is “not if the AI is going to give a more accurate answer “. It’s only a matter of time before every X-ray machine is connected to the cloud and one human doctor per hospital puts his hand on your shoulder when he reads you the output from the AI algorithm. Kind of like this:

Overpopulation is the most common objection people make to developing rejuvenation biotechnology and potentially increasing healthy human lifespan. We take a look at why that is and if the figures support this concern.

Any discussion of rejuvenation biotechnology almost certainly includes the subject of overpopulation and that objection medical advances that directly address the various processes of aging will lead to an overpopulated world. Such dire predictions are a common theme when advances in medicine that could increase human lifespans are concerned.

Overpopulation is a word that gives the simple fact of population growth a negative connotation. It implies that an increase in the number of people will harm our lives in different ways: it might be famine, scarcity of resources, excessive population density, increased risks of infectious diseases, or harm to the environment.

The first footage of DNA replication in real time has a shocking surprise.

Can we live to 1,000? It was outrageous when he said it at ideacity in 2008… and again in 2015. Now he’s back to update us on the incredible progress that has been made toward life extension.

Michael Kramer of Zoomer Radio talks with Aubrey de Grey at ideacity 2017. Aubrey de Grey is an English author and biomedical gerontologist, currently the Chief Science Officer of the SENS Research Foundation. Find out more about ideacity at http://www.ideacity.ca/ideacity-2017/

(Phys.org)—In the late 1800s when scientists were still trying to figure out what exactly atoms are, one of the leading theories, proposed by Lord Kelvin, was that atoms are knots of swirling vortices in the aether. Although this idea turned out to be completely wrong, it ushered in modern knot theory, which today is used in various areas of science such as fluid dynamics, the structure of DNA, and the concept of chirality.

Now in a new paper published in Physical Review Letters, mathematical physicist Paul Sutcliffe at Durham University in the UK has theoretically shown that nanoparticles called magnetic skyrmions can be tied into various types of knots with different magnetic properties. He explains that, in a sense, these nanoknots represent a “nanoscale resurrection of Kelvin’s dream of knotted fields.”

Skyrmions are the name of a general class of particles that are made by twisting a field. When this field is a magnetic field, the skyrmions are called magnetic skyrmions. Magnetic skyrmions have attracted a lot of attention recently due to their potential applications in spintronics, where electron spins (which are related to the electron’s magnetic properties) are exploited in the design of transistors, storage media, and related devices.
