Anthrobots: Scientists build tiny biological robots from human tracheal cells

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

Researchers at Tufts University and Harvard University’s Wyss Institute have created tiny biological robots that they call Anthrobots from human tracheal cells that can move across a surface and have been found to encourage the growth of neurons across a region of damage in a lab dish.

The multicellular robots, ranging in size from the width of a human hair to the point of a sharpened pencil, were made to self-assemble and shown to have a remarkable healing effect on other . The discovery is a starting point for the researchers’ vision to use patient-derived biobots as new therapeutic tools for regeneration, healing, and treatment of disease.

Gravitational waves from mega black-hole collision reveal long-sought ‘ringing’

Posted by in category: physics

In a groundbreaking discovery, researchers have identified evidence of long-sought vibrations resulting from the largest black-hole merger ever detected.

Researchers find massive merger’s signature aftershocks hidden in 2019 data from LIGO and Virgo detectors.

Dark, mysterious and consuming everything around them, black holes will rip apart anything that passes their event horizons. But could there be more? What would happen if you fell into one of those monstrosities? How could you possibly travel through the black hole itself? And if you emerged on the other side, where would you end up?

These Tiny, Wound-Healing Robots Start Life As Just 1 Human Cell

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

Regenerative medicine might just have had a new tool added to its arsenal: Scientists have created tiny biological robots out of living human cells. Though they may be small, the self-assembling bots are mighty, with a study demonstrating their potential for healing and treating disease.

The team had already proven their biological robotics chops back in 2020 with the creation of Xenobots, made from frog embryonic cells. They even managed to design Xenobots so that they could reproduce in a way that no living animal or plant does, something that had never been seen before.

Advancing Power Resilience: UC Santa Cruz’s AI Innovation in Microgrid Technology

Posted by in categories: information science, policy, robotics/AI, sustainability

A recent study published in IEEE Transactions on Control of Network Systems discusses how artificial intelligence (AI) can be used to control microgrids in the event of a long-term power outage caused by natural disasters or human error. This study was conducted by a team of researchers at UC Santa Cruz and holds the potential to improve power restoration techniques, which are traditionally controlled by local utility companies. One benefit of microgrids is they can function to power a small area, such as a town, until the primary utility source comes back online.

“Nowadays, microgrids are really the thing that both people in industry and in academia are focusing on for the future power distribution systems,” said Dr. Yu Zhang, who is an assistant professor of electrical and computer engineering at UC Santa Cruz and co-author on the study.

For the study, the researchers used an AI-based approach to develop a novel method where microgrids could draw power from renewable energy sources while being disconnected from the primary utility source, known as “islanding mode”, but can also function while being connected to the source, as well. This new method, which they refer to as constrained policy optimization (CPO), uses a machine learning algorithm that learns from outside input, such as real-time changes in environmental or power conditions, and makes the best-informed decisions on what to do next.

Ocean Conservation Unveiled: The Scuba Diver’s Perspective on MPAs in California

Posted by in category: sustainability

“People come from around the state and around the world to dive the Channel Islands, drawn by playful sea lions, underwater cathedrals of emerald kelp forests and giant sea bass weighing four times more than the divers themselves,” said Molly Morse.

Can marine protected areas (MPAs) have a positive effect on the scuba diving industry? This is something a recent study published in Marine Policy hopes to find out as a team of researchers led by the University of California, Santa Barbara (UCSB) highlighted the potential benefits that MPAs could have on ecotourism in California’s Channel Islands, specifically for scuba divers.

For the study, the researchers used data collected between 2016 and 2022 from an onboard vessel location system known as Automatic Identification System (AIS)—which boat captains use during scuba diving tours—and interviewed for-hire vessel captains with the goal of ascertaining the location of these ecotours with respect to MPAs and their corresponding borders of protection. In the end, the team found that the ecotours vessels favored MPAs for their activities, specifically for lobster fishing and scuba diving, and that 38 percent of the most popular ecotourism diving locations were within MPAs, with 45 percent of diving activities occurring within MPAs, as well.
