How to build a digital ‘twin’ of the human brain – what existing models overlook

How to build a digital ‘twin’ of the human brain – what existing models overlook

Published by skeptic

The potential to create personalised digital “twins” of your brain and body is a hot topic in neuroscience and medicine today. These computer models are designed to simulate how parts of your brain interact, and how the brain may respond to stimulation, disease or medication. The extraordinary complexity of the brain’s billions of neurons makes this a very difficult task, of course, even in the era of AI and big data. Until now, whole-brain models have struggled to capture what makes each brain unique. People’s brains are all wired slightly differently, so everyone has a unique network of neural connections that represents a kind of “brain fingerprint”. However, most so-called brain twins are currently more like distant cousins. Their performance is barely any closer to the real thing than if the model were using the wiring diagram of a random stranger. This matters because digital twins are increasingly proposed as tools for testing treatments by computer simulation, before applying them to real people. If these models fail to capture fundamental principles of each patient’s unique …

How a twin study untangled the surprising roots of authoritarian political beliefs

How a twin study untangled the surprising roots of authoritarian political beliefs

Published by José Betancourt

People who complete more years of formal education tend to score lower on measures of right-wing authoritarianism, a trait characterized by strict obedience to leaders and adherence to traditional norms. A recent study of twins reveals that while part of this connection may be a direct result of schooling, most of the link is explained by the childhood environments and genetics that siblings share. These results were recently published in the journal Personality and Social Psychology Bulletin. Following the horrors of the Second World War, psychologists initiated a massive effort to understand why certain populations enthusiastically support dictators and oppressive regimes. Understanding which factors lead people to support authoritarian regimes remains a matter of the greatest practical importance, just as it was when the academic field originated. Early researchers identified a personality profile they called right-wing authoritarianism. Individuals with high levels of this trait show a strong willingness to defer to established authorities, while demanding that others do the same. These individuals also desire to see others punished if they deviate from established social traditions, …

A New Digital Twin for Brain Activity Aims to Speed Research

A New Digital Twin for Brain Activity Aims to Speed Research

Can artificial intelligence help decode the human brain? A new study by finds that a new AI model is capable of acting as a “digital twin” of the human brain, capable of predicting human brain activity from visual, auditory, and language stimuli. The new model promise to vastly accelerate neuroscience research and promote understanding of the human brain. It is an understatement to say that the human brain is complex. It is challenging to conduct experiments in vivo on the brains of living human beings. Thus AI offers an in silico alternative that may greatly accelerate neuroscience research on how our brains work. AI is rapidly being applied in neurological imaging, diagnostics, early disease detection, neurotech devices, wearable brain monitors, surgical support, precision medicine, drug discovery, and neuroscience research. The worldwide market for AI in neurology is expected to reach $2.5 billionUSD by 2030, according to forecasts. Existing AI models are largely narrow point-solutions that were trained on smaller datasets. Traditional AI models are often designed for a targeted purpose that is narrow in scope, …

Hyundai is testing a new compact electric SUV that looks nearly identical to the Kia EV2. The new EV was spotted charging in public ahead of its upcoming debut. Hyundai tests new Kia EV2-like electric SUV After Kia opened EV2 orders in Europe last week, starting at just €26,600 ($30,500), Hyundai is preparing to launch its own compact electric SUV. The mysterious new EV has been spotted testing in public a few times now. We got our first look at it earlier this year after a prototype was caught driving near Hyundai’s Sriperumbudur plant in Chennai, India, or the “Detroit of Asia,” as it’s often called. While Hyundai has yet to reveal any details, the vehicle was labelled with an “HE1” tag, believed to be the IONIQ 1’s codename. Advertisement – scroll for more content Hyundai’s previous electric vehicles, like the IONIQ 5 and IONIQ 9, were labelled “ME” and “NE” with the “E” indicating they are based on the dedicated E-GMP platform. More recently, a camouflaged prototype was spotted at a charging station in …

The Lone Twin | Psychology Today

Published by Jenni Sidey

Twins of differing ages, from infants and children to adults, experience the loss of their twin in different ways. But always, no matter what, this is a devastating, highly sensitive and traumatic event for the twin who survives. It is sad and frightening even for the surviving twin’s family and close friends, and takes a long time to process. Perhaps young twins suffer more and in a different way and for a longer time because communicating their sense of emptiness and loneliness is extremely difficult. In some situations, non-verbal children will have behavioral problems that serve as clues to the terrible pain of losing their twin. For example, fighting with their parents (the bearers of the bad news), crying, and general unhappiness can be observed when a twin realizes his or her co-twin is not by their side and can’t be found in any of the usual places. There are different pathways that can help grieving twins. Often, later in life, memories of the lost twin will be recovered in bits and pieces. Many twins …

The 34-year-old singer, who welcomed the twins prematurely last May with Zion Foster, shared the diagnosis in an emotional Instagram video last year. She detailed the “gruelling three/four months” leading to the discovery, after an “endless” series of appointments confirmed her daughters had “a severe muscle disease called SMA Type 1.” Nelson has since begun campaigning for SMA1 screenings from birth, and started a petition to add the condition to the newborn blood spot screening test, also known as the heel prick test. In an emotional conversation with Health Secretary Wes Streeting on ITV’s This Morning, Nelson said: “It’s just madness to me …

Earlier this year, the 34-year-old announced that her twin girls, Ocean Jade and Story Monroe Nelson, had been diagnosed with spinal muscular atrophy (SMA), a genetic condition leading to progressive muscle wastage. Since then, Nelson has actively campaigned for universal newborn screening, highlighting how early treatment can prevent some of the most devastating impacts of the illness. In a post on her Instagram story on Monday, Nelson said: “Today my heart feels super heavy. It’s a very bittersweet moment knowing that Scotland had become the first UK nation to screen babies for SMA. “We’re so close yet so far. “I will never be able to understand why we still do not …

Engineer Says It’s Time to Rebuild the Twin Towers as Giant Data Centers With Anti-Aircraft Lasers on the Roof

Engineer Says It’s Time to Rebuild the Twin Towers as Giant Data Centers With Anti-Aircraft Lasers on the Roof

Published by José Betancourt

Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech After their grisly destruction in a terror attack in 2001 — and the chaotic and deadly wars that followed — it can be hard to remember that the World Trade Center’s Twin Towers, originally completed in 1973, were architecturally controversial for their impact on the Manhattan skyline. Now, a long-shot effort seeks to rebuild them in an unlikely locale: Chicago, where they’d be reborn as massive data centers. Behind the campaign is Raphael Chryslar, who might seem like an unlikely candidate for the project. Currently residing in Hatfield, England, he was just a toddler when the original Twin Towers fell. Trained in aerospace engineering — and a self-described author, photographer, entrepreneur, and aspiring architect and astronaut — Chryslar is clearly a superfan of the originals: he’s even gone so far as to get a tribute to the original World Trade Center tattooed on his arm. Called the World Tech Center, Chryslar’s project envisions nine buildings across a 35-acre …
