Intelligent brains take longer to solve difficult problems, shows simulation study

Posted by in category: neuroscience

Do intelligent people think faster? Researchers at the BIH and Charité—Universitätsmedizin Berlin, together with a colleague from Barcelona, made the surprising finding that participants with higher intelligence scores were only quicker when tackling simple tasks, while they took longer to solve difficult problems than subjects with lower IQ scores.

In personalized brain simulations of the 650 participants, the researchers could determine that brains with reduced synchrony between literally “jump to conclusions” when making decisions, rather than waiting until upstream brain regions could complete the processing steps needed to solve the problem.

In fact, the brain models for higher score participants also needed more time to solve challenging tasks but made fewer errors. The scientists have now published their findings in the journal Nature Communications.

‘You can 3D print one material through another, as if it were invisible’: New 3D printing technique

Posted by in categories: 3D printing, materials

Scientists have developed an advanced technique for 3D printing that is set to revolutionize the manufacturing industry.

The group, led by Dr. Jose Marques-Hueso from the Institute of Sensors, Signals & Systems at Heriot-Watt University in Edinburgh, has created a new method of 3D printing that uses near-infrared (NIR) light to create complex structures containing multiple materials and colors.

They achieved this by modifying a well-established 3D known as stereolithography to push the boundaries of multi-material integration. A conventional 3D printer would normally apply a blue or UV laser to a that is then selectively solidified, layer by layer, to build a desired object. But a major drawback of this approach has been the limitations in intermixing materials.

The alien-hunting team at SETI has a new test for humanity to decipher messages sent from an alien race

Posted by in category: alien life

Someone in here can figure this out.


SETI hasn’t detected a real message from aliens so it decided to simulate one and see how people reacted and how long it would take to decode.

How AI could change the ways we live and work, reducing the digital divide

Posted by in categories: business, economics, education, employment, robotics/AI

AI is everywhere. Its use is being debated in headlines, on social media and around dinner tables. To some, the rate of AI acceleration is concerning, with many technology leaders calling for a six-month pause in the training of new systems to better understand the impact such tools are having. To others, AI is seen as the cornerstone of the fourth industrial revolution, the latest disruptive technology opening up possibilities for new ways of learning, working and living that we have never experienced before.

Yet, disruptive technologies are nothing new. They have been changing the way we live and work for decades. And these changes have not been without consequences, particularly in the form of economic dislocation and social upheaval. Automation in manufacturing has streamlined mass production and driven down costs; Ecommerce platforms have reshaped the way we shop and do business; even online education has found new ways to provide flexible and affordable ways of learning, delivering opportunities to millions across the globe that simply were not available before.

Presently, much of the discussion around the impact of AI is based on conjecture. However, it is widely agreed that it will have a major impact on jobs and even has the potential to call into question the very fundamentals of what work is. What is not understood is how AI will play out across society in the longer term. Will it, like previous technological revolutions, deliver short-term disruptions followed by long-term benefits, or will it be the catalyst for new ways of learning and upskilling and help reduce the widening digital divide?

Brainwashing: Signs That You Are Being Brainwashed (Without Even Realizing It)

Posted by in category: futurism

You might even go so far as to think of the term brainwashing in relation to propaganda spread during the First and Second World Wars, in order to influence vast amounts of people.

But what exactly is brainwashing and should we confine it to the past?

The term brainwashing was first coined in the 1950’s during the Korean War. It was used to explain how totalitarian regimes were able to completely indoctrinate American soldiers through a process of torture and propaganda.

Mitigating Operational Risk In Healthcare With High-Performance Pharmacies

Posted by in categories: finance, health

Guy, a recognized industry thought leader, is the president of SmartSense, IoT solutions for the enterprise.

It’s no secret that healthcare systems exist at the intersection of financial risk and operational risk. Amid the market volatility of our current socioeconomic environment, the pressure is on hospitals, clinics and blood banks to maintain healthy profit margins that enable them to keep pace with rising demand for clinical care and prescription medications. The rate of U.S. spending on prescriptions is increasing at a rapid clip, and considering physician-administered drugs provide hospitals with high gross profits, investing in pharmaceutical services is a logical pathway to profitability.

However, severe pharmaceutical compliance regulations related to safety and efficacy—CDC, VFC, FDA, AABB and BOP—create a myriad of risk management issues for healthcare organizations to juggle. In the U.S., adverse drug effects are one of the most common medical errors. All it takes is one mismanaged medication to put a patient’s health at significant risk. And on a global scale, widespread vaccine hesitancy rooted in public skepticism has served as a critical roadblock to mitigating the spread of severe infectious diseases like Covid-19.

Quantum Physics Could Explain Nearly All the Mysteries of How Life Works

Posted by in categories: biological, particle physics, quantum physics

Quantum effects are phenomena that occur between atoms and molecules that can’t be explained by classical physics. It has been known for more than a century that the rules of classical mechanics, like Newton’s laws of motion, break down at atomic scales. Instead, tiny objects behave according to a different set of laws known as quantum mechanics.

For humans, who can only perceive the macroscopic world, or what’s visible to the naked eye, quantum mechanics can seem counterintuitive and somewhat magical. Things you might not expect happen in the quantum world, like electrons “tunneling” through tiny energy barriers and appearing on the other side unscathed or being in two different places at the same time in a phenomenon called superposition.

I am trained as a quantum engineer. Research in quantum mechanics is usually geared toward technology. However, and somewhat surprisingly, there is increasing evidence that nature – an engineer with billions of years of practice — has learned how to use quantum mechanics to function optimally. If this is indeed true, it means that our understanding of biology is radically incomplete. It also means that we could possibly control physiological processes by using the quantum properties of biological matter.

Scientists ‘stunned’

Posted by in categories: cosmology, physics

An international team of astrophysicists has discovered hundreds of mysterious structures in the centre of the Milky Way.

The one-dimensional cosmic threads are made up of hundreds of horizontal or radial filaments, slender, elongated bodies of luminous gas that potentially originated a few million years ago — and seem to be pointing the direction of the black hole.

“I was actually stunned when I saw these. We had to do a lot of work to establish that we weren’t fooling ourselves,” added Yusef-Zadeh, who’s also a member of the Center for Interdisciplinary Exploration and Research in Astrophysics.
