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.

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!
Posted in computing, neuroscience
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
Posted in health, neuroscience
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.

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.

Anxiety is one of most prevalent mental health disorders, with 1 out of 14 people around the world being likely affected. Leading up to conditions such as depression, increased risk for suicide, disability and requirement of high health services, very few people who often need treatment actually receive it…
In her talk “How to cope with anxiety”, Olivia Remes of the University of Cambridge will share her vision on anxiety and will unravel ways to treat and manage this health disorder. Arguing that treatments such as psychotherapy and medication exist and often result in poor outcome and high rates of relapses, she will emphasise the importance of harnessing strength in ourselves as we modify our problem-coping mechanisms.
Olivia will stress that by allowing ourselves to believe that what happens in life is comprehensive, meaningful, and manageable, one can significantly improve their risk of developing anxiety disorders. At TEDxUHasselt 2017, Olivia will stress that by allowing ourselves to believe that what happens in life is comprehensive, meaningful, and manageable, one can significantly improve their risk of developing anxiety disorders.

Researchers at UCLA (University of California, Los Angeles) conducted a study in 2012 on rats and found that a diet high in fructose hinders learning skills and memory and also slow down the brain. The researchers found that rats who over-consumed fructose had damaged synaptic activity in the brain, meaning that communication among brain cells was impaired.
Study’s lead author Dr. Fernando Gomez-Pinilla said in a statement that “Insulin is important in the body for controlling blood sugar, but it may play a different role in the brain. Our study shows that a high-fructose diet harms the brain as well as the body.”
In addition to the damaging effects on cognition and mood, sugar also has drug-like effects in the reward system of the brain. Neuroscientist Nicole Avena presented the effect of sugar on our brains and bodies in TED-Ed’s animated installment.
