How Our Reality May Be a Sum of All Possible Realities

Posted by in category: physics

Richard Feynman’s path integral is both a powerful prediction machine and a philosophy about how the world is. But physicists are still struggling to figure out how to use it, and what it means.

Scientists develop first fabric to automatically cool or insulate depending on conditions

Posted by in categories: innovation, materials

Despite decades of innovation in fabrics with high-tech thermal properties that keep marathon runners cool or alpine hikers warm, there has never been a material that changes its insulating properties in response to the environment. Until now.

University of Maryland researchers have created a that can automatically regulate the amount of heat that passes through it. When conditions are warm and moist, such as those near a sweating body, the fabric allows (heat) to pass through. When conditions become cooler and drier, the fabric reduces the heat that escapes. The development was reported in the February 8, 2019 issue of the journal Science.

The researchers created the fabric from specially engineered yarn coated with a conductive metal. Under hot, , the strands of yarn compact and activate the coating, which changes the way the fabric interacts with infrared . They refer to the action as “gating” of infrared radiation, which acts as a tunable blind to transmit or block heat.

Quebec Hospital Using Virtual Reality to Address Increasing Mental Health Issues from the Pandemic

Posted by in categories: biotech/medical, health, neuroscience, virtual reality

A Quebec hospital adopts a novel use of VR to help patients with anxiety, phobias and pain.

In a newswire release today, the Fondation de l’Hôtel-Dieu d’Alma (the Alma Hospital Foundation) announced the launch of a virtual reality (VR) project aimed at improving the mental health of those experiencing increasing anxiety. The Alma Hospital is a regional health centre for the area of Lac St. Jean and the Saguenay River valley to the north of Quebec City.

Jean Lamoureux, the hospital’s Executive Director states, “The number of requests for mental-health consultations is estimated to have increased by 30 to 40 percent during the pandemic. These needs are urgent…and, thanks to the innovation of Paperplane Therapeutics and TELUS, we will transform the way health services are delivered, while having a significant positive impact on patient well-being through technology.”

The Power Source of The Universe — Can Nuclear Fusion Help us Reach Type 1 Civilization?

Posted by in categories: biotech/medical, nuclear energy

Human civilization has achieved some incredible things during its short reign on this planet. Technological development over the past 5,000 years of human civilization has led our species to dominance of life on Earth and placed us on a pathway to achieving a Type I civilization.

To reach even the basic level of a “Kardashev Type 1 civilization” we must do two things:
Develop more advanced technology and share it with all responsible nations.
Make renewable energy accessible to all parts of the world.

Oldest brain in a backboned animal found in fish fossil

Posted by in categories: biotech/medical, neuroscience

Very old brain, some ancient philosophy maybe…

A fossilised fish originally dug up more than a century ago in an English coal mine has been shown to hold the world’s oldest brain in a vertebrate animal.

CT scans revealed the new internal features including a brain and cranial nerves about 2 centimetres long.

Clap if you believe in robot fairies

“I’ll teach you how to jump on the wind’s back, and then away we go,” Peter Pan says to Wendy.

In J.M. Barrie’s book, fairies can be brought back to life if enough people believe in them.

Echolocation could give small robots the ability to find lost people

Posted by in categories: drones, information science, robotics/AI

Scientists and roboticists have long looked at nature for inspiration to develop new features for machines. In this case, researchers from Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland were inspired by bats and other animals that rely on echolocation to design a method that would give small robots that ability to navigate themselves — one that doesn’t need expensive hardware or components too large or too heavy for tiny machines. In fact, according to PopSci, the team only used the integrated audio hardware of an interactive puck robot and built an audio extension deck using cheap mic and speakers for a tiny flying drone that can fit in the palm of your hand.

The system works just like bat echolocation. It was designed to emit sounds across frequencies, which a robot’s microphone then picks up as they bounce off walls. An algorithm the team created then goes to work to analyze sound waves and create a map with the room’s dimensions.

In a paper published in IEEE Robotics and Automation Letters, the researchers said existing “algorithms for active echolocation are less developed and often rely on hardware requirements that are out of reach for small robots.” They also said their “method is model-based, runs in real time and requires no prior calibration or training.” Their solution could give small machines the capability to be sent on search-and-rescue missions or to previously uncharted locations that bigger robots wouldn’t be able to reach. And since the system only needs onboard audio equipment or cheap additional hardware, it has a wide range of potential applications.
