DOLE, France (Reuters) — Growing global demand for food is putting a squeeze on available land and one French startup says it has the answer: indoor insect farming.
Ynsect raised $224 million from investors including Hollywood star Robert Downey Jr.’s Footprint Coalition this month to build a second insect farm in Amiens in northern France.
The company breeds mealworms that produce proteins for livestock, pet food and fertilisers, and will use the funds to build what it says will be the world’s largest insect farm.
“In a breakthrough study published on February 19th in Nature Biomedical Engineering, researchers connected neural dust implants reduced to 1.7 cubic millimeters to rat sciatic nerves. The implanted device, called the StimDust system, consisted of very few components, which will be scaled down for future applications. A piezoceramic ultrasonic transducer generated power allowing for wireless communication and stimulation. A capacitor stored any excess energy generated from ultrasonic beams. Bipolar stimulating electrodes directly interfaced with the nerve while a cuff attached to a small circuit-board allowed the device to adhere physically to the nerve. These components were sufficient to generate or record nerve-impulses. In anesthetized rodents, they elicited muscular contractions with the StimDust system.”
While Neuralink, Elon Musk’s startup-venture focused on creating a brain-computer interface, garners lots of coverage in the biotechnology space, other bioelectronics ventures continue innovating in this space.
iota Biosciences, a spin-off company from UC Berkley formed in 2017, made news two years ago by securing $15 million in Series A funding and again last year announcing a partnership with Astellas Pharma Inc. Bolstered by studies in rodents, iota Biosciences advances towards their vision. In a press release on their partnership, founders Jose Carmena and Michel Maharbiz commented:

Following the first-ever triple Raptor Static Fire test, Starship SN8 is pushing through the pre-launch milestones. The nosecone has since been installed – resulting in the first full Starship stack since MK1 – allowing for a second Static Fire test this coming week. The second Static Fire test will involve propellant being fed from the Header Tank system.
SN8 passed through the first major objective in impressive fashion, progressing in a staggered manner with a preburner attempt aborted, followed by a preburner test involving at least two of the Raptors.

A 20-year project to reintroduce the species across the peninsula has seen their numbers rise to 855.
SpaceX launched its first crewed mission to ISS in May this year. The company demonstrated its spacecraft is safe and reliable to carry humans to space and back. Axiom’s space tourist mission with SpaceX is scheduled to be a 10-day journey that will launch civilians aboard Crew Dragon to the space station atop a Falcon 9 rocket. The space tourists will stay at ISS for 8 days, where they will experience microgravity and amazing views of our planet.
SpaceX’s first private civilian flight will carry three Axiom customers who will fly alongside former NASA Astronaut Michael Lopez-Alegria, he will be commander during the mission. Earlier this year, NASA and SpaceX announced Hollywood actor Tom Cruise will film a movie at the space station and fly aboard Crew Dragon. Then, reports surfaced about Cruise and his film production agency working with Axiom is responsible for providing ‘training, mission planning, hardware development, life support, medical support, crew provisions, hardware and safety certifications, on-orbit operations and overall mission management.’ However, Axiom has not officially disclosed who their private passengers will be on their first mission in collaboration with SpaceX.
Microsoft, in collaboration with MITRE research organization and a dozen other organizations, including IBM, Nvidia, Airbus, and Bosch, has released the Adversarial ML Threat Matrix, a framework that aims to help cybersecurity experts prepare attacks against artificial intelligence models.
With AI models being deployed in several fields, there is a rise in critical online threats jeopardizing their safety and integrity. The Adversarial Machine Learning (ML) Threat Matrix attempts to assemble various techniques employed by malicious adversaries in destabilizing AI systems.
AI models perform several tasks, including identifying objects in images by analyzing the information they ingest for specific common patterns. The researchers have developed malicious patterns that hackers could introduce into the AI systems to trick these models into making mistakes. An Auburn University team had even managed to fool a Google LLC image recognition model into misclassifying objects in photos by slightly adjusting the objects’ position in each input image.
If humans want to travel about the solar system, they’ll need to be able to communicate. As we look forward to crewed missions to the Moon and Mars, communication technology will pose a challenge we haven’t faced since the 1970s.
We communicate with robotic missions through radio signals. It requires a network of large radio antennas to do this. Spacecraft have relatively weak receivers, so you need to beam a strong radio signal to them. They also transmit relatively weak signals back. You need a large sensitive radio dish to capture the reply. For spacecraft beyond the orbit of Earth, this is done through the Deep Space Network (DSN), which is a collection of radio telescopes custom designed for the job.
The only major crewed mission we currently have is the International Space Station (ISS). Since the ISS orbits only about 400 kilometers above the Earth, it’s relatively easy to send radio signals back and forth. But as humans travel deeper into space, we’ll require a Deep Space Network far more powerful than the current one. The DSN is already being pushed to its data limits, given the large number of active missions. Human missions would require orders of magnitude more bandwidth.
