Reductio ad absurdum

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

Oh, the logic of objections against rejuvenation! bigsmile


If you’ve ever tried to advocate for rejuvenation, you know it is hard. Usually, people deem the idea as crazy/impossible/dangerous well before you get to finish your first sentence. Living too long would be boring, it would cause overpopulation, ‘immortal’ dictators, and what you have. However, you’ve probably never heard anyone use the same arguments to say that we should not cure individual age-related diseases. This is largely because people have little to no idea about what ageing really is, and how it cannot be untangled from the so-called age-related pathologies. These are nothing more, nothing less, than the result of the life-long accumulation of several types of damage caused by the body’s normal operations. Unlike infectious diseases, the diseases of old age are not the result of a pathogen attack, but essentially of your own body falling apart. As I was saying, people are largely unaware of this fact, and therefore expect that the diseases of ageing could be cured one by one without having to interfere with the ageing process itself, as if the two weren’t related at all. The result of this false expectation would be that you could cure Alzheimer’s, Parkinson’s, etc., but somehow old people would still drop dead around the age of 80 just because they’re old. That’s like saying they died of being healthy.

Back to reality, this can’t be done. To cure the diseases of old age, you need to cure ageing itself. If, for whatever reason, you think that curing ageing as a whole would be a bad idea and it should not be done, the only option is to not cure at least some of the root causes of ageing. Consequently, some age-related pathologies would remain as untreatable as they are today.

Now, the typical objections raised against rejuvenation tend to sound reasonable at first. To some, the statement ‘We should not cure ageing because it would lead to overpopulation’ sounds self-evident. However, if we consider the implications of this statement, things start getting crazy. As said, not curing ageing implies not curing some of its root causes, which in turn implies not curing some age-related diseases. Therefore, the sentence ‘We should not cure ageing’ implies ‘We should not cure [insert age-related disease here] . What happens when we reformulate typical objections to rejuvenation in this fashion?

Salk scientists reverse signs of aging in mice

Posted by in categories: biotech/medical, life extension

Scientists at the Salk Institute have found that intermittent expression of genes normally associated with an embryonic state can reverse the hallmarks of old age. This approach, which not only prompted human skin cells in a dish to look and behave young again, also resulted in the rejuvenation of mice with a premature aging disease, countering signs of aging and increasing the animals’ lifespan by 30 percent. The early-stage work provides insight both into the cellular drivers of aging and possible therapeutic approaches for improving human health and longevity.

Revolutionary approach for treating glioblastoma works with human cells

Posted by in categories: biotech/medical, neuroscience

Finally, maybe hope for GBM patients.


In a rapid-fire series of breakthroughs in just under a year, researchers at the University of North Carolina at Chapel Hill have made another stunning advance in the development of an effective treatment for glioblastoma, a common and aggressive brain cancer. The work, published in the Feb. 1 issue of Science Translational Medicine, describes how human stem cells, made from human skin cells, can hunt down and kill human brain cancer, a critical and monumental step toward clinical trials — and real treatment.

Last year, the UNC-Chapel Hill team, led by Shawn Hingtgen, an assistant professor in the Eshelman School of Pharmacy and member of the Lineberger Comprehensive Care Center, used the technology to convert mouse skin cells to stem cells that could home in on and kill human brain cancer, increasing time of survival 160 to 220 percent, depending on the tumor type. Now, they not only show that the technique works with human cells but also works quickly enough to help patients, whose median survival is less than 18 months and chance of surviving beyond two years is 30 percent.

Scientists show deep brain stimulation blocks heroin relapse in rats

Posted by in categories: biotech/medical, neuroscience

Scientists at The Scripps Research Institute (TSRI) have found that deep brain stimulation (DBS) can greatly reduce the compulsion to use heroin in standard rat models of addiction.

Rats that were used to taking , and normally would have self-administered more and more of the drug, did not escalate their intake when treated with DBS.

The treatment involves the weak electrical stimulation, via implanted electrodes, of a brain region called the subthalamic .

Mapping the Brain Before Surgery for Epilepsy

Great method btw.


Epilepsy is the fourth most common neurological disorder in the United States. Patients who have it are of all ages and it can seriously limit one’s ability to enjoy life. It’s a spectrum disorder which means the kinds of seizures people suffer and how they are managed will vary depending on the patient. Currently about 3 million people in the US are living with epilepsy and experts predict that at least 1 in 26 people will develop epilepsy at some point in their lifetime. While epilepsy is most often treated with anti-seizure medication, there are some patients who have not benefitted from medication. This form of the disorder is called drug-resistant epilepsy and can be very difficult to treat.
