Robotic engineers from Harvard’s Wyss Institute and John A. Paulson School for Engineering and Applied Science (SEAS) have developed a laser-steering microrobot that can be integrated with existing endoscopic tools, which are used in minimally invasive surgeries.
The ends of endoscopic tools must be highly flexible to enable visualization and manipulation of the surgical site in the target tissue.
In the case of energy-delivering endoscopic tools, which allow surgeons to cut or dry tissues and stop internal bleeds, a heat-generating energy source is added to the end of the device. ....

Autonomous robot swarm swims like a school of fish

Autonomous robot swarm swims like a school of fish
These underwater robots operate as a collective artificial intelligence.
Researchers have devised a swarm of small fish-inspired robots that can synchronize their movements by themselves, without any human input. The autonomous robots essentially mimic the behavior of a school of fish in nature, exhibiting a realistic, complex three-dimensional collective behavior.
Each robo-fish (called a ‘Bluebot’) is equipped with cameras and sensors that enable it to track its neighbors and get a sense of direction. This is a step beyond the typical multi-robot communication system, in which individual bots have to communicate with each other via radio and constantly transmit their GPS data. ....

Schools of fish exhibit complex, synchronized behaviors that help them find food, migrate and evade predators. No one fish or team of fish coordinates these movements nor do fish communicate with each other about what to do next. Rather, these collective behaviors emerge from so-called implicit coordination individual fish making decisions based on what they see their neighbors doing. ....

Inducing immunity to cancer | Harvard Magazine

A miniature device the size and shape of an aspirin tablet could provide new options for people with cancer. Developed in the lab of Pinkas Family professor of bioengineering David Mooney, the implantable vaccine, inserted under a patient’s skin, operates like a tiny factory where immune cells of one kind are transformed to train other immune cells to eradicate tumors.
The tablet-like device emits a signal that attracts dendritic cells, the messengers of the immune system, which carry information about the pathogens and toxins they encounter to other immune cells. The dendritic cells “literally crawl inside the plastic device” to be activated by freeze-dried fragments of the patient’s own tumor, Mooney explains. Once the dendritic cells have become activated, they “home to the nearest lymph node,” where they encounter T cells that they train to recognize and destroy cancer cells. The T cells then multiply and circulate through the body, dissolving the patient’s ....
