Autonomous Racing Drones Are Starting To Beat Human Pilots

Posted by in categories: drones, mapping, robotics/AI

Even with all the technological advancements in recent years, autonomous systems have never been able to keep up with top-level human racing drone pilots. However, it looks like that gap has been closed with Swift – an autonomous system developed by the University of Zurich’s Robotics and Perception Group.

Previous research projects have come close, but they relied on optical motion capture settings in a tightly controlled environment. In contrast, Swift is completely independent of remote inputs and utilizes only an onboard computer, IMU, and camera for real-time for navigation and control. It does however require a pretrained machine learning model for the specific track, which maps the drone’s estimated position/velocity/orientation directly to control inputs. The details of how the system works is well explained in the video after the break.

The paper linked above contains a few more interesting details. Swift was able to win 60% of the time, and it’s lap times were significantly more consistent than those of the human pilots. While human pilots were often faster on certain sections of the course, Swift was faster overall. It picked more efficient trajectories over multiple gates, where the human pilots seemed to plan one gate in advance at most. On the other hand human pilots could recover quickly from a minor crash, where Swift did not include crash recovery.

One hour of training is all you need to control a third robotic arm

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

A new study by researchers at Queen Mary University of London, Imperial College London and The University of Melbourne has found that people can learn to use supernumerary robotic arms as effectively as working with a partner in just one hour of training.

The study, published in the IEEE Open Journal of Engineering in Medicine and Biology, investigated the potential of supernumerary robotic arms to help people perform tasks that require more than two hands. The idea of human augmentation with additional artificial limbs has long been featured in science fiction, like in Doctor Octopus in The Amazing Spider-Man (1963).

“Many tasks in , such as opening a door while carrying a big package, require more than two hands,” said Dr. Ekaterina Ivanova, lead author of the study from Queen Mary University of London. “Supernumerary robotic arms have been proposed as a way to allow people to do these tasks more easily, but until now, it was not clear how easy they would be to use.”

Medical Venture’s iPSC-Based Heart Failure Treatment Breaks New Ground

Posted by in categories: biotech/medical, innovation

In a groundbreaking clinical trial, two patients suffering from severe heart failure experienced improvements in their symptoms through an innovative procedure. The clinical trial was conducted by Heartseed, a medical venture associated with Keio University in Tokyo’s Shinjuku Ward.

The procedure involves the transplantation of “cardiomyocyte spheroids” (CM spheroids), spherical clusters of heart muscle cells derived from induced pluripotent stem cells (iPSCs). This development represents a significant step forward in the treatment of heart failure using iPSCs, with plans for practical implementation set for around 2025.

Japanese venture Heartseed has found that treating heart failure with iPSC-derived cardiomyocyte spheroids could achieve sustained tissue regeneration.

Optimizing CAR T cell therapy with bridging radiation therapy

Posted by in category: biotech/medical

For many patients diagnosed with certain types of B-cell lymphoma, leukemia and multiple myeloma, chimeric antigen receptor (CAR) T cell therapy offers an effective treatment option. This cellular therapy is created by extracting a patient’s T cells, modifying them in a lab to identify and attack cancer cells, and returning them to the patient.

The process of creating the CAR T cells can take three to four weeks. Radiation therapy can be a tool to help get a patient through this manufacturing period. This is called bridging therapy.

“Bridging therapy can help control the disease so that a patient can get to the CAR T cell infusion,” says radiation oncologist Penny Fang, M.D. Research from Fang and her colleagues examines the role of bridging therapy for B-cell lymphoma patients receiving CAR T cell therapy. Their latest findings will be presented at the 2023 American Society for Radiation Oncology Annual Meeting.

Artificial Intelligence Improves Brain Tumor Diagnosis

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

Neurosurgeons can leave the operating room more confident today than ever before about their patient’s brain tumor diagnosis, thanks to the integration of a new system that employs optical imaging and artificial intelligence that are making brain tumor diagnosis quicker and more accurate. This technology is allowing them to quickly see diagnostic tissue and tumor margins in near-real time.

A new highly precise measurement of the hypertriton lifetime

Posted by in category: particle physics

A hypertriton is a tritium nucleus in which a neutron is replaced by a so-called Lambda hyperon. This type of hypernucleus was first discovered in the 1950s has since been the key focus of numerous studies.

The ALICE collaboration, a large research group that studies the collisions of nuclei inside CERN’s large hadron collider (LHC) in Switzerland, recently measured the lifetime of a hypertriton with remarkable precision. Their paper, published in Physical Review Letters, is a further step forward toward understanding the unique properties of these fascinating nuclear complexes.

“As the first and lightest hypernucleus (i.e., a nucleus that includes a baryon with at least one strange quark) ever identified, the hypertriton holds a special place in ,” Maximiliano Puccio, part of the ALICE collaboration, told
