Complex shapes of photons to boost future quantum technologies

Posted by in categories: computing, neuroscience, quantum physics

As the digital revolution has now become mainstream, quantum computing and quantum communication are rising in the consciousness of the field. The enhanced measurement technologies enabled by quantum phenomena, and the possibility of scientific progress using new methods, are of particular interest to researchers around the world.

Recently two researchers at Tampere University, Assistant Professor Robert Fickler and Doctoral Researcher Markus Hiekkamäki, demonstrated that two– interference can be controlled in a near-perfect way using the spatial shape of the photon. Their findings were recently published in the prestigious journal Physical Review Letters.

“Our report shows how a complex light-shaping method can be used to make two quanta of light interfere with each other in a novel and easily tuneable way,” explains Markus Hiekkamäki.

Reversing a Genetic Cause of Poor Stress Tolerance

Posted by in categories: biotech/medical, genetics, neuroscience

Stress management.


Everyone faces stress occasionally, whether in school, at work, or during a global pandemic. However, some cannot cope as well as others. In a few cases, the cause is genetic. In humans, mutations in the OPHN1 gene cause a rare X-linked disease that includes poor stress tolerance. Cold Spring Harbor Laboratory (CSHL) Professor Linda Van Aelst seeks to understand factors that cause specific individuals to respond poorly to stress. She and her lab studied the mouse gene Ophn1, an analog of the human gene, which plays a critical role in developing brain cell connections, memories, and stress tolerance. When Ophn1 was removed in a specific part of the brain, mice expressed depression-like helpless behaviors. The researchers found three ways to reverse this effect.

To test for stress, the researchers put mice into a two-room cage with a door in between. Normal mice escape from the room that gives them a light shock on their feet. But animals lacking Ophn1 sit helplessly in that room without trying to leave. Van Aelst wanted to figure out why.

Autism-related conditions linked to altered visual perception

Posted by in categories: genetics, neuroscience

Autistic people tend to switch between images more slowly than non-autistic people do, a previous study shows. And they spend more time seeing a combination of the two images.


Children with genetic conditions linked to autism perform atypically on a test of binocular rivalry, according to a new unpublished study.

Researchers presented the work virtually today at the 2021 International Society for Autism Research annual meetin g. (Links to abstracts may work only for registered conference attendees.)

Largest autism genetics analysis to date uncovers more high-confidence candidates

Posted by in categories: biotech/medical, computing, genetics, neuroscience

After doubling its sample size, the largest study of genetic data from autistic people has identified 255 genes associated with the condition, an increase of more than 40 genes since the researchers’ 2019 update; 71 of the genes rise above a stringent statistical bar the team had not previously used. The new analysis also adds data from people with developmental delay or schizophrenia and considers multiple types of mutations.

“It’s a really significant step forward in what we do,” said Kyle Satterstrom, a computational biologist in Mark Daly’s lab at the Broad Institute in Cambridge, Massachusetts. Satterstrom presented the findings virtually on Tuesday at the 2021 International Society for Autism Research annual meeting. (Links to abstracts may work only for registered conference attendees.)

The team’s previous analyses used data from the Autism Sequencing Consortium, which enrolls families through their doctors. The researchers mainly scoured the genetic data to find rare, non-inherited mutations linked to autism.

From Fringe to Mainstream: Experiential Realism of the Evolving Conscious Mind

Posted by in categories: computing, neuroscience, particle physics, quantum physics

Our physical space-time reality isn’t really “physical” at all, its apparent solidity of objects, as well as any other associated property such as time, is an illusion. As a renowned physicist Niels Bohr once said: “Everything we call real is made of things that cannot be regarded as real.” But what’s not an illusion is your subjective experience, i.e., your consciousness; that’s the only “real” thing, according to proponents of Experiential Realism. It refers to interacting entangled conscious agents at various ontological levels, giving rise to conscious experience all the way down, and I’d argue all the way up, seemingly ad infinitum. It’s a “matryoshka” of embedded realities: conscious minds within larger minds.

#ExperientialRealism


So, why Experiential Realism? From the bigger picture perspective, we are here for experience necessary for evolution of our conscious minds. Our limitations, such as our ego, belief traps, political correctness, our very human condition define who we are, but the realization that we largely impose those limitations on ourselves gives us more evolvability and impetus to overcome these self-imposed limits to move towards higher goals and state of being.

The Schizophrenic World Of Quantum Interpretations

Posted by in categories: military, neuroscience, quantum physics

I believe that schizophrenia although an illness could be a quantum sense in the quantum realm essentially feeling different dimensions which still remain unknown. The minds developed by the military in different projects like the stranger things series is an example of such a wild reality we live in and how interesting dimensions beyond ours touch our reality.


To the average person, most quantum theories sound strange, while others seem downright bizarre. There are many diverse theories that try to explain the intricacies of quantum systems and how our interactions affect them. And, not surprisingly, each approach is supported by its group of well-qualified and well-respected scientists. Here, we’ll take a look at the two most popular quantum interpretations.

Does it seem reasonable that you can alter a quantum system just by looking at it? What about creating multiple universes by merely making a decision? Or what if your mind split because you measured a quantum system?

Partners of People With Schizophrenia and Bipolar Disorder Have Often a Mental Disorder

Posted by in category: neuroscience

Summary: Almost fifty percent of people who have children with partners suffering from schizophrenia or bipolar disorder also have mental health challenges, a new study reports.

Source: Aarhus University.

Almost half of the parents who have children together with a parent with schizophrenia or bipolar disorder, are themselves burdened by psychological issues. This can affect family life and the children. This is shown in the research result from the major Danish psychiatry project iPSYCH.

Something Is Frizzling Up the Brains of Old White Guys

Posted by in categories: life extension, neuroscience, sustainability

“This work confirms that there is a link between air pollution and how well the aging brain works,” senior study author and Columbia University researcher Andrea Baccarelli told The Guardian. “These shorter-term effects are reversible: when air pollution clears, our brain reboots and starts working back to its original level. However, multiple occurrences of these higher exposures cause permanent damage.”


Thankfully, it’s reversible.
