Autonomous robot surgeon prototype stitches pigs’ colons better than human and human-assisted robot surgeons:

In his proof-of-concept study, the STAR system stitched together two parts of a pig’s colon. The researchers likened this task to reconnecting a cut garden hose—and just like the hose, if the stitching is done imperfectly, the colon can be prone to leaks that can be life-threatening. Using the vision system and a pressure sensor at the end of the robotic arm, the STAR tool automatically placed sutures in the tissue to reconnect it, both in tissue in the lab and inside living pigs. The researchers then compared the STAR’s performance to that of a surgeon performing the same task with a laparoscopic tool as well as a robot-assisted surgery in which the surgeon controls the robot.

Comparing the uniformity of the sutures, number of mistakes and the highest pressure that the tissue could withstand without leaking, the STAR system performed better than the human and the human-directed robot. None of the living pigs had any complications from the operations.


Welcome to the age of autonomous surgery.

The more da Vinci’s the better, if you ask me!


An international team of scholars has just unveiled plans to science the shit out of Leonardo da Vinci, the man who gave us the Mona Lisa and envisioned futuristic technologies like helicopters and tanks 500 years ago. Goals of the fledgling “Leonardo Project” include recovering the famous Renaissance figure’s remains and reconstructing his genetic code.

The Leonardo Project brings together geneticists, genealogists, archaeologists, and art historians from Italy, Spain, France, the United States and elsewhere. “This is a fabulous, interdisciplinary project,” said Rhonda Roby, a geneticist at the Craig Venter Institute in California, who will be contributing its expertise in genomic reconstruction to the effort.

By examining everything from paintings and notebooks to the DNA of living relatives, the team hopes to glean new insights into Leonardo’s life, diet, physical appearance, and genetic predispositions. If they’re very lucky, the researchers may be able to reconstruct most or all of Leonardo’s genome.

Here is the real challenge to ask the average parent or grandparent on the street: are you willing to allow your 5 year old child or grandchild to have a brain tumor removed by an autonomous robot without any trained & experienced surgeon or nurse supervision?


An unmanned robot has been used to stitch together a pig’s bowel, moving science a step closer to automated surgery, say experts.

Unlike existing machines, the Star robot is self-controlled — it doesn’t need to be guided by a surgeon’s hands.

In tests on pigs, it at least matched trained doctors at mending cut bowel, Science Translational Medicine reports.

How could global economic inequality survive the onslaught of synthetic organisms, micromanufacturing devices, additive manufacturing machines, nano-factories?

Neurosurgeons using lasers to treat brain cancer have discovered that the technique breaks down the blood-brain barrier, a finding that could lead to new treatment options for patients with the deadly disease.

The blood-brain barrier is sort of a natural “security system” that shields the brain from toxins in the blood but also blocks potentially helpful drugs such as those used in chemotherapy.

“We were able to show that this blood-brain barrier is broken down for about four weeks after you do this laser therapy,” said Dr. Eric Leuthardt, a professor of neurosurgery at Washington University in St. Louis. “So not only are you killing the tumor, you are actually opening up a window of opportunity to deliver various drugs and chemicals and therapies that could otherwise not get there.”

Today, we’re announcing a new series of workshops and an interagency working group to learn more about the benefits and risks of artificial intelligence.

There is a lot of excitement about artificial intelligence (AI) and how to create computers capable of intelligent behavior. After years of steady but slow progress on making computers “smarter” at everyday tasks, a series of breakthroughs in the research community and industry have recently spurred momentum and investment in the development of this field.

Today’s AI is confined to narrow, specific tasks, and isn’t anything like the general, adaptable intelligence that humans exhibit. Despite this, AI’s influence on the world is growing. The rate of progress we have seen will have broad implications for fields ranging from healthcare to image- and voice-recognition. In healthcare, the President’s Precision Medicine Initiative and the Cancer Moonshot will rely on AI to find patterns in medical data and, ultimately, to help doctors diagnose diseases and suggest treatments to improve patient care and health outcomes.

A novel way of synthesising a promising new antibiotic has been identified by scientists at the University of Bristol. By expressing the genes involved in the production of pleuromutilin in a different type of fungus, the researchers were able to increase production by more than 2,000 per cent.

With resistance growing to existing antibiotics, there is a vital and urgent need for the discovery and development of new antibiotics that are cost effective. Promising developments are derivatives of the antibiotic pleuromutilin, which are isolated from the mushroom Clitopilus passeckerianus.

These new compounds are some of the only new class of antibiotics to join the market recently as human therapeutics. Furthermore, with their novel mode of action and lack of cross-resistance, pleuromutilins and their derivatives represent a class with further great potential, particularly for treating resistant strains such as methicillin-resistant Staphylococcus aureus (MRSA) and extensively drug resistant tuberculosis (XTB).
