Sony has shown off its new surgical robot doing some super-precise work sewing up a tiny slit in a corn kernel. It’s the first machine of its kind that auto-switches between its different tools, and has successfully been tested in animal surgery.

It’s designed to help in the field of super-microsurgery, a highly specialized field in which surgeons operate on extremely small blood vessels and nerves, with diameters well under 1 mm (0.04 in). As you might imagine, this kind of thing requires incredibly steady hands, and specialists in this field often do their work whole looking through a microscope.

Thus, it’s an ideal place for some robotic assistance, and there are a number of surgical robots already in clinical use from companies like Intuitive Surgical, Stryker and others. We’re not talking fully autonomous AI-powered robot surgeons here, we’re talking teleoperation tools that allow surgeons to magnify their vision while shrinking their hand motions.

A substantial proportion of people with a traumatic brain injury who had their life support withdrawn may have survived and at least partially recovered, a study suggests.

Traumatic brain injuries can occur due to a forceful blow, a jolt to the head or an object entering the brain, such as a bullet…


After comparing people with brain injuries whose life support was continued with those who had it turned off, scientists calculated that around 40 per cent in the latter group may have made some recovery.

All 14 trial participants, including 12 adults (ages 17 to 63) and two children (ages 10 and 14), were born with a form of Leber Congenital Amaurosis (LCA) caused by mutations in the centrosomal protein 290 (CEP290) gene. They underwent a single injection of a CRISPR/Cas9 genome editing medicine, EDIT-101 in one eye via a specialized surgical procedure. This trial, which included the first patient to ever receive a CRISPR-based investigational medicine directly inside the body, focused primarily on safety with a secondary analysis for efficacy.

No serious treatment or procedure-related adverse events were reported, nor were there any dose-limiting toxicities. For efficacy, the researchers looked at four measures: best-corrected visual acuity (BCVA); dark-adapted full-field stimulus testing (FST), visual function navigation (VNC, as measured by a maze participants completed), and vision-related quality of life.

Summary: Researchers use AI to reveal distinct cellular-level differences in the brains of men and women, focusing on white matter. These findings show AI can accurately identify sex-based brain patterns invisible to human eyes.

The study suggests that understanding these differences can enhance diagnostic tools and treatments for brain disorders. This research emphasizes the need for diversity in brain studies to ensure comprehensive insights into neurological diseases.

Immunotherapy can boost the survival of early-stage lung cancer patients eligible for surgery when it’s combined with chemotherapy, a new clinical trial reports.

Those who got immunotherapy before and after surgery — along with pre-surgical chemo — had a 42% lower risk of cancer progression, recurrence or death than those who only received chemo, according to findings published Wednesday in the New England Journal of Medicine.

Further, about 25% of those who got immunotherapy and chemo had no cancer at all remaining after their surgery, compared with about 5% of those who got chemo alone.

In episode 267 of the Stem Cell Podcast, we chat with Dr. Shankar Srinivas, a Professor of Developmental Biology in the Department of Physiology Anatomy and Genetics based in the Institute for Developmental and Regenerative Medicine at the University of Oxford. He is also a Zeitlyn Fellow and Tutor in Medicine at Jesus College. Using mouse and human embryos as model systems, his group looks at the control of patterning and morphogenesis during the establishment of the anterior-posterior axis, gastrulation, and early cardiogenesis. He discusses how tissues respond to forces during early development, characterizing cardiac progenitors, and training internationally.
