Psychedelics Unlock Learning Windows in the Brain

Posted by in categories: biotech/medical, neuroscience

Summary: Researchers discovered a unique property of psychedelic drugs: their ability to reopen “critical periods” in the brain, times when the brain is highly susceptible to environmental learning signals. These periods, usually associated with skills development like language learning, are reopened by psychedelics for different lengths of time.

This breakthrough in understanding psychedelic drug function may have therapeutic implications for conditions like stroke and deafness. Further, it uncovers novel molecular mechanisms influenced by psychedelics.

Video Game Algorithm Unlocks Molecular Mysteries of Brain Cells

Posted by in categories: biotech/medical, information science, life extension, neuroscience

Summary: Researchers leveraged a tracking algorithm from video games to study molecules’ behavior within live brain cells.

They adapted the fast and accurate algorithm used to track bullets in combat games for use in super-resolution microscopy. The innovative approach enables scientists to observe how molecules cluster together to perform specific functions in space and time within the brain cells.

The data obtained could shed light on molecular functions’ disruption during aging and disease.

Amyotrophic lateral sclerosis (ALS): Virus-like protein may be key

Posted by in category: biotech/medical

A recent study suggests that an ancient, virus-like protein may play a key role in amyotrophic lateral sclerosis (ALS), a fatal and incurable condition. The finding may lead to new research avenues for ALS treatments.

A brilliant cosmic burst 100 times as bright as our galaxy came from 2 black holes circling each other, study finds

Posted by in category: cosmology

The smaller black hole, with a mass of about 150 million suns, orbits its larger companion, with a mass of 18 billion suns, at near the speed of light.

It’s this rapid dance that sparked the bright flare from this system, according to a new study published in Monthly Notices of the Royal Astronomical Society in March.

The recorded burst, which astronomers observed in February 2022, occurred when the smaller black hole crashed into a disk of gas surrounding the larger black hole, the study’s scientists said.

Scientists Predict Never-Before-Seen Crystal Structures With Unexpected Chemistry

Posted by in categories: chemistry, information science, particle physics

Ultra-high pressure can have strange effects in physics and chemistry, and in a new study, high-pressure modeling has led to the prediction of four new compounds: compounds that don’t form in normal ways, have crystal structures we’ve never seen before, and can even act as superconductors in certain temperatures.

Those compounds are Li14 Cs, Li8Cs, Li7Cs, and Li6Cs, and they’re all formed from lithium (Li) and cesium (Cs) – though not in a conventional way. All four are superconductors, which means electricity can flow through them without resistance or energy loss.

The scientists behind the study used a special crystal structure prediction algorithm called USPEX (Universal Structure Predictor: Evolutionary Xtallography) to find these new compounds. It’s known as an evolutionary algorithm, using a range of methods to figure out the probability of how atoms will link together.

Healthcare Robot with ‘Sense of Touch’ Could Reduce Infection Spread

Posted by in categories: biotech/medical, robotics/AI

A first-of-its-kind robot which gives clinicians the ability to ‘feel’ patients remotely has been launched as part of a Finnish hospital pilot by deep tech robotics company Touchlab, a new tenant of the world-leading centre for robotics and artificial intelligence the National Robotarium.

Controlled by operators wearing an electronic haptic glove, the Välkky telerobot is equipped with the most advanced electronic skin (e-skin) technology ever developed to transfer a sense of touch from its robotic hand to users. E-skin is a material which is made up of single or multiple ultra-thin force sensors to transmit tactile sensations like pressure, vibration or motion from one source to another in real-time.

The 3-month pilot at Laakso Hospital in Helsinki, Finland will see a team of purpose-trained nurses explore how robotics systems can help deliver care, reduce workload and prevent the spread of infections or diseases. The pilot at Laakso Hospital is coordinated by Forum Virium Helsinki, an innovation company for the City of Helsinki. The research is part of a wider €7 billion project aimed at developing the most advanced hospital in Europe, due to be completed in 2028.

Researchers design a fabric that actively regulates temperature with the flip of a switch

Posted by in categories: chemistry, mobile phones, wearables

A study, published in PNAS Nexus, describes a fabric that can be modulated between two different states to stabilize radiative heat loss and keep the wearer comfortable across a range of temperatures.

Po-Chun Hsu, Jie Yin, and colleagues designed a made of a layered semi-solid electrochemical cell deployed on nylon cut in a kirigami pattern to allow it to stretch and move with the wearer’s body. Modern clothes are made with a variety of insulating or breathable fabrics, but each fabric offers only one thermal mode, determined by the fabric’s emissivity: the rate at which it emits .

The in the fabric can be electrically switched between two states—a transmissive dielectric state and a lossy metallic state—each with different emissivity. The fabric can thus keep the wearer comfortable by adjusting how much body heat is retained and how much is radiated away. A user would feel the same skin temperature whether the external temperature was 22.0°C (71.6°F) or 17.1°C (62.8°F). The authors call this fabric a “wearable variable-emittance device,” or WeaVE, and have configured it to be controlled with a .
