In this landmark talk, Peter Diamandis shares how we are rapidly heading towards a human-scale transformation, the next evolutionary step into what he calls a “Meta-Intelligence,” a future in which we are all highly connected — brain to brain via the cloud — sharing thoughts, knowledge and actions.
He highlights the 4 driving forces as well as the 4 steps that is transforming humanity.

In 2014 Fortune Magazine named Peter Diamandis as one of the World’s 50 Greatest Leaders.

There has been a spike in severe psychological distress in young Australian adults under 35, according to new analysis from The Australian National University (ANU).

The study—which tracked 3,155 Australians—is the first-of-its-kind to compare mental health data before and during the COVID-19 pandemic.

“Young Australians aged 18 to 24 and those aged 25 to 34 are significantly worse off in terms of mental health than those who are older,” Associate Professor Ben Edwards, from the ANU Centre for Social Research and Methods, said.

When the novel coronavirus roared into the U.S., mental health took a back seat to physical health. The number one priority was making sure hospitals wouldn’t be overwhelmed and that as many lives as possible could be saved.

Schools closed, remote work became the norm, restaurants shuttered and getting together with friends was no longer possible. The news cycle spun with story after story highlighting the ever-increasing number of cases and deaths, while unemployment soared to levels not seen since the Great Depression.

Any one of these shifts could be expected to cause an increase in mental health issues. Put together, they created a a perfect storm for a crisis.

Many Australians have welcomed the gradual easing of coronavirus restrictions. We can now catch up with friends and family in small numbers, and get out and about a little more than we’ve been able to for a couple of months.

All being well, restrictions will continue to be lifted in the weeks and months to come, allowing us slowly to return to some kind of “normal”.

This is good news for the economy and employment, and will hopefully help ease the high levels of distress and mental health problems our community has been experiencing during the pandemic.

For centuries, people have been using mindfulness meditation to try to relieve their pain, but neuroscientists have only recently been able to test if and how this actually works. In the latest of these efforts, researchers at University of California San Diego School of Medicine measured the effects of mindfulness on pain perception and brain activity.

The study, published July 7, 2022 in Pain, showed that mindfulness meditation interrupted the communication between brain areas involved in pain sensation and those that produce the sense of self. In the proposed mechanism, pain signals still move from the body to the brain, but the individual does not feel as much ownership over those pain sensations, so their pain and suffering are reduced.

“One of the central tenets of mindfulness is the principle that you are not your experiences,” said senior author Fadel Zeidan, Ph.D., associate professor of anesthesiology at UC San Diego School of Medicine. “You train yourself to experience thoughts and sensations without attaching your ego or sense of self to them, and we’re now finally seeing how this plays out in the brain during the experience of acute pain.”

Older people with underactive thyroid, which is formally called hypothyroidism, may be at increased risk of developing dementia, according to a new research study published in the July 6, 2022, online issue of Neurology, the medical journal of the American Academy of Neurology. According to the find.

How the brain functions is still a black box: scientists aren’t even sure how many kinds of nerve cells exist in the brain. To know how the brain works, they need to know not only what types of nerve cells exist, but also how they work together. Researchers at the Salk Institute have gotten one step closer to unlocking this black box.

Using cutting-edge visualization and genetic techniques, the team uncovered a new subtype of nerve cell, or neuron, in the visual cortex. The group also detailed how the new cell and two similar neurons process images and connect to other parts of the brain. Learning how the brain analyzes visual information at such a detailed level may one day help doctors understand elements of disorders like schizophrenia and autism.

“Understanding these cell types contributes another piece to the puzzle uncovering neural circuits in the brain, circuits that will ultimately have implications for neurological disorders,” says Edward Callaway, Salk professor and senior author of the paper published December 6 in the journal Neuron.

Clinical studies have demonstrated a strong association between Alzheimer’s disease (AD) and delirium. A change to the Tau protein, which can lead to the formation of tangles in brain, is one of the hallmarks of AD pathology, and Tau phosphorylation at threonine 217 (Tau-PT217) and threonine 181 (Tau-PT181) are new plasma biomarkers that can detect early-stage AD. A clinical study led by investigators at Massachusetts General Hospital (MGH) has shown that plasma Tau-PT217 and Tau-PT181 are associated with incidence and severity of postoperative delirium. The findings are published in Annals of Surgery.

Early studies from the same research group at MGH have shown that the ratio of beta amyloid (which causes AD’s signature plaques) to Tau in cerebrospinal fluid is associated with postoperative delirium. Recent studies in other labs have reported that plasma Tau-PT181 concentration distinguishes AD dementia from other neurological disorders. Plasma levels of Tau-PT217 are associated with the changes in cerebrospinal fluid levels of Tau-PT217 and AD development.

In this current study, the team at MGH developed a novel method to measure Tau-PT217 and Tau-PT181 concentrations in plasma of patients, called nanoneedle technology, in collaboration with NanoMosaic (Woburn, MA). “The nanoneedle technology is ultrasensitive, requires a small volume, and can measure low concentrations of molecules, including Tau-PT217 and Tau-PT181,” says lead author Feng Liang, MD, Ph.D., in the Department of Anesthesia, Critical Care and Pain Medicine at MGH. “More than 20,000 nanoneedles are integrated on a silicon substrate assigned to detect one analyte. Each nanoneedle is a single molecule biosensor functionalized with antibodies,” says Liang.

The human brain may be the most complex piece of organized matter in the known universe, but Allen Institute researchers have begun to unravel the genetic code underlying its function. Research published this month in Nature Neuroscience identified a surprisingly small set of molecular patterns that dominate gene expression in the human brain and appear to be common to all individuals, providing key insights into the core of the genetic code that makes our brains distinctly human.

“So much research focuses on the variations between individuals, but we turned that question on its head to ask, what makes us similar?” says Ed Lein, Ph.D., Investigator at the Allen Institute for Brain Science. “What is the conserved element among all of us that must give rise to our unique cognitive abilities and human traits?”

Researchers used data from the publicly available Allen Human Brain Atlas to investigate how gene expression varies across hundreds of functionally distinct brain regions in six human brains. They began by ranking genes by the consistency of their expression patterns across individuals, and then analyzed the relationship of these genes to one another and to brain function and association with disease.
