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.

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.

Architecture firm Skidmore, Owings & Merrill (SOM) has presented ‘Urban Sequoia’ – a concept for transforming the built environment into a network for absorbing carbon.

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.

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.

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.

“It is like using your thumb to control the water spray from a hose,” said Ming Liu, associate professor in UC Riverside’s Marlan. “You know how to get the desired spraying pattern by changing the thumb position, and likewise, in the experiment, we read the light pattern to retrieve the details of the object blocking the five nm-sized light nozzles.”

The light is then focused into a spectrometer, where it forms a tiny ring shape. The researchers can formulate the absorption and scattering images with colors by scanning the probe over an area and recording two spectra for each pixel.

The team expects the new nano-imaging technology can be an important tool to help the semiconductor industry make uniform nanomaterials with consistent properties for use in electronic devices. The new full-color nano-imaging technique could also be used to improve understanding of catalysis, quantum optics, and nanoelectronics.
