Hacking Reality [Official Film]

Posted by in categories: cosmology, mathematics, media & arts, particle physics

Is there an 8-dimensional “engine” behind our universe? Join Marion Kerr on a fun, visually exciting journey as she explores a mysterious, highly complex structure known simply as ‘E8’–a weird, 8-dimensional mathematical object that for some, strange reason, appears to encode all of the particles and forces of our 3-dimensional universe.

Meet surfer and renowned theoretical physicist Garrett Lisi as he rides the waves and paraglides over the beautiful Hawaiian island of Maui and talks about his groundbreaking discovery about E8 relates deeply to our reality; and learn why Los Angeles based Klee Irwin and his group of research scientists believe that the universe is essentially a 3-dimensional “shadow” of this enigmatic… thing… that may exist behind the curtain of our reality.

Scientists develop 3D-printed epifluidic electronic skin

Posted by in categories: biotech/medical, chemistry, health, robotics/AI, wearables

In a recent study published in Science Advances, researchers from the California Institute of Technology, led by Dr. Wei Gao, have developed a machine learning (ML)–powered 3D-printed epifluidic electronic skin for multimodal health surveillance. This wearable platform enables real-time physical and chemical monitoring of health status.

Wearable health devices have the potential to revolutionize the medical world, offering tracking, personalized treatments, and early diagnosis of diseases.

However, one of the main challenges with these devices is that they don’t track data at the molecular level, and their fabrication is challenging. Dr. Gao explained why this served as a motivation for their team.

Dopamine Might Have An Unexpected Function That Could Reshape Our Understanding Of Brain Conditions

Posted by in categories: cybercrime/malcode, food, neuroscience, sex

Dopamine seems to be having a moment in the zeitgeist. You may have read about it in the news, seen viral social media posts about “dopamine hacking,” or listened to podcasts about how to harness what this molecule is doing in your brain to improve your mood and productivity. However, recent neuroscience research suggests that popular strategies to control dopamine are based on an overly narrow view of how it functions.

Dopamine is one of the brain’s neurotransmitters — tiny molecules that act as messengers between neurons. It is known for its role in tracking your reaction to rewards such as food, sex, money, or answering a question correctly. There are many kinds of dopamine neurons located in the uppermost region of the brainstem that manufacture and release dopamine throughout the brain. Whether neuron type affects the function of the dopamine it produces has been an open question.

Recently published research reports a relationship between neuron type and dopamine function, and one type of dopamine neuron has an unexpected function that will likely reshape how scientists, clinicians, and the public understand this neurotransmitter.

Training Your Heart And Muscles Could Be The Key to Brain Health in Old Age

Posted by in categories: health, neuroscience

People in the oldest stage of life who regularly engage in aerobic activities and strength training exercises perform better on cognitive tests than those who are either sedentary or participate only in aerobic exercise. That is the key finding of our new study, published in the journal GeroScience.

We assessed 184 cognitively healthy people ranging in age from 85 to 99. Each participant reported their exercise habits and underwent a comprehensive battery of neuropsychological tests that were designed to evaluate various dimensions of cognitive function.

We found that those who incorporated both aerobic exercises, such as swimming and cycling, and strength exercises like weightlifting into their routines – regardless of intensity and duration – had better mental agility, quicker thinking and greater ability to shift or adapt their thinking.

Farm robots inspired by ant brains

Posted by in categories: food, robotics/AI, sustainability

With the rapid-paced rise of AI in everyday life, nothing, not even the traditional farmer, is untouched by the technology.

A survey of the latest generation of farm tools provides a taste of just how far modern farming has come.

The Ecorobotix, a seven-foot-wide GPS-assisted “table on wheels” as some have described it, is a solar battery-powered unit that roams crop fields and destroys weeds with pinpoint precision. It boasts a 95% efficiency rate, with virtually no waste.

Solar cell material can assist self-driving cars in the dark

Posted by in categories: robotics/AI, solar power, sustainability, transportation

Material used in organic solar cells can also be used as light sensors in electronics. This has been shown by researchers at Linköping University, Sweden, who have developed a type of sensor able to detect circularly polarized red light. Their study, published in Nature Photonics, paves the way for more reliable self-driving vehicles and other uses where night vision is important.

Some beetles with shiny wings, firefly larvae and colorful mantis shrimps reflect a particular kind of light known as circularly polarized light. This is due to in their shell that reflect the electromagnetic light waves in a particular way.

Circularly polarized light also has many technical uses, such as satellite communication, bioimaging and other sensing technologies. This is because circularly polarizing light carries a vast amount of information, due to the fact that the around the light beam spirals either to the right or to the left.
