Chip implants make humans more efficient

My new Op-Ed for The San Francisco Chronicle: http://www.sfchronicle.com/opinion/openforum/article/Chip-im…003194.php #transhumanism

Wisconsin company Three Square Market recently announced it will become the first U.S. company to offer its employees chip implants that can be scanned at security entrances, carry medical information and even purchase candy in some vending machines. A company in Europe already did this last year.

For many people, it sounds crazy to electively have a piece of technology embedded in their body simply for convenience’s sake. But a growing number of Americans are doing it, including me.

I got my RFID implant two years ago, and now I use it to send text messages, bypass security codes on my computer, and open my front door. Soon I’ll get the software to start my car, and then my life will be totally keyless.

The type of chip implants in humans varies depending on the manufacturer or purpose of the device. A few hundred thousand people around the world have cochlear implants, which allow deaf people to hear. Others have implants to help with Alzheimer’s, Parkinson’s or even depression. A growing number of transhumanists — people who want to use radical technology in their bodies — have the $60 implant I have. It’s tiny, about the size of a grain of rice, and is injected into the body by a syringe. The injection process — usually in the hand near the thumb — is often bloodless and takes seconds to complete.

Who are you? How the story of human origins is being rewritten

Think again, because over the past 15 years, almost every part of our story, every assumption about who our ancestors were and where we came from, has been called into question. The new insights have some unsettling implications for how long we have walked the earth, and even who we really are.

The past 15 years have called into question every assumption about who we are and where we came from. Turns out our evolution is more baffling than we thought.

WHO do you think you are? A modern human, descended from a long line of Homo sapiens? A distant relative of those great adventure-seekers who marched out of the cradle of humanity, in Africa, 60,000 years ago? Do you believe that human brains have been getting steadily bigger for millions of years, culminating in the extraordinary machine between your ears?

Study: Eye Test Could Predict Alzheimer’s Disease Years In Advance

An eye test could predict whether someone could have Alzheimer’s disease years in advance, according to a recent study.

Researchers from Cedars-Sinai and company NeuroVision Imaging found the disease affects the retina, which is the back of the eye, in a similar way to how it impacts the brain. Through this discovery, researchers conducted a noninvasive eye scan in an effort to detect key signs of Alzheimer’s before patients began experiencing symptoms of the disease.

The study, which was published Tuesday in JCI Insight, said a high definition eye scan was able to see the plaque in the retina, which correlated with the amount in the brain. The plaque is a buildup of toxic proteins called amyloid-beta deposits, which are key signs of Alzheimer’s. Build up in the brain may occur as early as two decades before people begin to experience signs of the disease.

Will Gene Editing Allow Us to Rid the World of Diseases?

Scientists recently used a gene-editing tool to fix a mutation in a human embryo. Around the world, researchers are chasing cures for other genetic diseases.

Now that the gene-editing genie is out of the bottle, what would you wish for first?

Babies with “perfect” eyes, over-the-top intelligence, and a touch of movie star charisma?

Elephants Never Forget!

It’s a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth. Alex Gendler takes us into the incredible, unforgettable mind of an elephant.

It’s a common saying that elephants never forget, but these magnificent animals are more than giant walking hard drives. The more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative and benevolent creatures on Earth.

Stress and Brain: Jaime Tartar

Jaime Tartar tells us about how the brain interprets what is stressful, how it determines our behavioral and physiological response to stressors, and how it can be damaged by stress. She will discuss how the body’s reaction to acute stress has protective and adaptive effects in the short run while chronic stress can lead to poor health consequences such as decreased memory performance and depression.

Brain & Consciousness

John Searle one of the world’s great philosophers of mind and language, has spent fifty years stimulating thinking around the world. What he says about consciousness as a biological phenomenon will challenge you! Cogitation, Consciousness & The Brain.

I’m going to talk about consciousness. Why consciousness? Well, it’s a curiously neglected subject, both in our scientific and our philosophical culture. Now why is that curious? Well, it is the most important aspect of our lives for a very simple, logical reason, namely, it’s a necessary condition on anything being important in our lives that we’re conscious.

In this talk during the first International Longevity and Cryopreservation Summit in Madrid in 2017 (http://longevitycryopreservationsummi…), prepared in collaboration with Keith Comito, LEAF/Lifespan.io President, longevity advocate Elena Milova reviews sociological studies of public attitudes towards the concept of life extension and corresponding technologies

She goes on to detail which expressions and messages can increase public acceptance and which have proven to be counterproductive. Related cognitive biases are also briefly discussed.

Elena is a LEAF/Lifespan.io Director of the Board and the head of its Outreach/Fundraising committee, and has been a longevity activist and advocate since 2013. Since then she has organized educational events to make new evidence-based methods of healthy life extension more popular, and is member of the Russian transhumanist movement.
