Boosting Memory Performance by Finding Amplitude of Brain Waves and Speeding Oscillations
Posted by Dan Breeden in category: neuroscience
Summary: Entrainment can safely manipulate brain waves to induce improvements in memory, a new study reveals.
Source: Florida Institute of Technology.
The brain is made of millions of cells called neurons, that send electrical messages to talk to each other in patterns of vertical electric activity called oscillations. By inducing them first, then finding the amplitude of the specific brain waves is improved during memory, ultimately memory performance itself is boosted. Once introduced, what if a person can boost the speed of these oscillations to improve memory? A university study in a journal for adolescents may show we can.

3D-printed ‘living ink’ is full of microbes and can release drugs
Posted by Genevieve Klien in categories: biotech/medical, materials
An ink made using engineered bacterial cells can be 3D-printed into structures that release anti-cancer drugs or capture toxins from the environment.
The microbial ink is the first printable gel to be made entirely from proteins produced by E.coli cells, without the addition of other polymers.
“This is the first of its kind… a living ink that can respond to the environment. We have repurposed the matrix that these bacteria normally utilise as a shielding material to form a bio-ink,” says Avinash Manjula-Basavanna at the Massachusetts Institute of Technology in Boston.

Explainable AI is about to become mainstream: The AI audits are here — Impact of AI recruitment bias audit in New York city
Posted by Genevieve Klien in category: robotics/AI
Candidates can ask for an explanation or a human review.
‘AI’ includes all technologies – from decision trees to neural networks.
The regulation is needed and already, there is discussion about adding ageism and disabilities to this audit.
Prepare to be Baffled.
The misconception is that electrons carry potential energy around a complete conducting loop, transferring their energy to the load. This video was sponsored by Caséta by Lutron.

World’s first wingless, compact eVTOL aircraft moves a step closer to reality
Posted by Shailesh Prasad in categories: biotech/medical, innovation
Urban Aeronautics, the Israel-based aerospace company behind the world’s first compact, wingless electric vertical takeoff, and landing (eVTOL) vehicle, is getting closer to turning its groundbreaking concept into reality. The company said it has raised the first $10 million of a $100 million funding round this week towards CityHawk from private investors in the US, Brazil, and Israel.
According to the company, the car-sized, six-seater CityHawk has more in common with birds than with nearly every other eVTOL prototype in existence. With a distinct, wingless exterior and patented fully-enclosed Fancraft rotor system, the CityHawk is mainly designed for commercial air charters and emergency medical services (EMS). It will be fueled by hydrogen, the most sustainable technology in development today. This means it must be able to conduct multiple trips within a city per day with zero emissions and minimal noise.

Corny Lithium-Ion Batteries Could Hold Quadruple the Charge
Posted by Shailesh Prasad in categories: chemistry, energy, nanotechnology, sustainability, transportation
The extra juice comes from a secret ingredient…corn starch.
Could a simple materials change make electric car batteries able to four times more energy? Scientists in South Korea think so. In a new paper in the American Chemical Society’s Nano Letters, a research team details using silicon and repurposed corn starch to make better anodes for lithium ion batteries.
This team is based primarily in the Korea Institute of Science and Technology (KIST), where they’ve experimented with microemulsifying silicon, carbon, and corn starch into a new microstructured composite material for use as a battery anode. This is done by mixing silicon nanoparticles and corn starch with propylene gas and heating it all to combine.

Scientists got an animal to breathe without oxygen
Posted by Shailesh Prasad in category: neuroscience
A team of scientists has discovered a technique to keep tadpoles alive despite removing their capacity to breathe — by injecting algae into the little froglets’ brains, turning their heads a bright, almost neon, green.
What the frog? Plants, such as algae, produce oxygen through photosynthesis. Animals, on the other hand, cannot — we typically use lungs or gills to filter it from the environment.
