Robot performs laparoscopic surgery without guiding hand of a human

February 2, 2022 by Editor Leave a Comment

By Catherine Graham, Johns Hopkins University

In four experiments on pig tissues, the robot excelled at suturing two ends of intestine – one of the most intricate and delicate tasks in abdominal surgery

A robot has performed laparoscopic surgery on the soft tissue of a pig without the guiding hand of a human – a significant step toward fully automated surgery on humans.

Designed by a team of Johns Hopkins University researchers, the Smart Tissue Autonomous Robot, or STAR, is described today in Science Robotics.

Senior author Axel Krieger, an assistant professor of mechanical engineering at Johns Hopkins’ Whiting School of Engineering, says: “Our findings show that we can automate one of the most intricate and delicate tasks in surgery: the reconnection of two ends of an intestine.

Sydney scientists achieve ‘99 per cent accuracy’ for quantum computing in silicon

January 27, 2022 by Editor Leave a Comment

UNSW Sydney-led researchers their findings “pave the way for large silicon-based quantum processors for real-world manufacturing and application”.

Australian researchers say they have proven that near error-free quantum computing is possible, paving the way to build silicon-based quantum devices compatible with current semiconductor manufacturing technology. (See video below.)

“Today’s publication shows our operations were 99 per cent error-free,” says Professor Andrea Morello of UNSW, who led the work with partners in the US, Japan, Egypt, and at UTS and the University of Melbourne.

“When the errors are so rare, it becomes possible to detect them and correct them when they occur. This shows that it is possible to build quantum computers that have enough scale, and enough power, to handle meaningful computation.” [Read more…] about Sydney scientists achieve ‘99 per cent accuracy’ for quantum computing in silicon

Perseverance’s first year on Mars: Purdue professor, mission team member looks at what is ahead

January 24, 2022 by Editor Leave a Comment

Almost one year into the Mars rover mission, accomplishing its goal is on the horizon for Purdue University’s Briony Horgan and the Perseverance team.

February 18 will mark one year since the rover landed on the red planet following a seven-month, 300-million-mile flight across space.

Horgan, associate professor of planetary science in the Purdue College of Science’s Department of Earth, Atmospheric, and Planetary Sciences, says anticipation is building as the team focuses on the mission goal: researching a now-dry large river delta.

Fastest DNA sequencing technique helps undiagnosed patients find answers in mere hours

January 17, 2022 by Editor Leave a Comment

A research effort led by Stanford scientists set the first Guinness World Record for the fastest DNA sequencing technique, which was used to sequence a human genome in just 5 hours and 2 minutes.

A new ultra-rapid genome sequencing approach developed by Stanford Medicine scientists and their collaborators was used to diagnose rare genetic diseases in an average of eight hours – a feat that’s nearly unheard of in standard clinical care.

“A few weeks is what most clinicians call ‘rapid’ when it comes to sequencing a patient’s genome and returning results,” said Euan Ashley, MB ChB, DPhil, professor of medicine, of genetics and of biomedical data science at Stanford.

Zero CO2 emissions ‘spaceplane’ parts to be manufactured in Sydney

January 13, 2022 by Editor Leave a Comment

Aerospace engineering startup Hypersonix Launch Systems has signed a Master Research Collaboration Agreement (MRCA) with the University of Sydney to research and manufacture the components of a zero emissions, hypersonic spaceplane – a launch vehicle capable of deploying small satellites into low earth orbit (LEO).

Named Delta Velos, the vehicle will be powered by four green hydrogen-fuelled scramjet engines, enabling carbon neutral propulsion.

It will also include the world’s first 3-D printed fixed geometry (no moving parts) scramjet engine in Australia, completed under the Australian Commercialisation grant awarded to Hypersonix in August 2020. [Read more…] about Zero CO2 emissions ‘spaceplane’ parts to be manufactured in Sydney

Ancient DNA reveals the world’s oldest family tree

January 6, 2022 by Editor Leave a Comment

Analysis of ancient DNA from one of the best-preserved Neolithic tombs in Britain has revealed that most of the people buried there were from five continuous generations of a single extended family.

By analysing DNA extracted from the bones and teeth of 35 individuals entombed at Hazleton North long cairn in the Cotswolds-Severn region, the research team was able to detect that 27 of them were close biological relatives.

The group lived approximately 5700 years ago – around 3700-3600 BC – around 100 years after farming had been introduced to Britain. [Read more…] about Ancient DNA reveals the world’s oldest family tree

Russian researchers present ultra-precise brain imaging tool

August 19, 2021 by Editor

A joint team from the Russian Quantum Center, Skoltech, and the Higher School of Economics has presented a novel supersensitive solid-state magnetometer operating at room temperature. The researchers for the first time used it to detect and record brain electrical activity with a technique called magnetoencephalography, which could become dozens of times cheaper with the new device. The paper was published in Human Brain Mapping.

High accuracy is a key advantage of magnetoencephalography (MEG) over other similar techniques used for studying the electrical activity of the brain. Biological tissues are transparent for magnetic fields. However, only a very limited number of laboratories around the world have MEG equipment, which uses either extremely cold liquid helium or high-temperature gas and is very expensive and difficult to manufacture.

A team from the Russian Quantum Center (RQC) developed a new sensor using yttrium-iron garnet films. This is the first solid-state supersensitive room-temperature magnetometer in the world. It is based on a quantum sensor and is capable of registering very weak or deep electrical sources in the brain. Owing to its wide dynamic range, the device requires less magnetic shielding, which means a lower cost of both the hardware and the entire research infrastructure.

Study takes unprecedented peek into life of 17,000-year-old mammoth

August 18, 2021 by Editor

An international research team has retraced the astonishing lifetime journey of an Arctic woolly mammoth, which covered enough of the Alaska landscape during its 28 years to almost circle the Earth twice.

Scientists gathered unprecedented details of its life through analysis of a 17,000-year-old fossil from the University of Alaska Museum of the North. By generating and studying isotopic data in the mammoth’s tusk, they were able to match its movements and diet with isotopic maps of the region.

Few details have been known about the lives and movements of woolly mammoths, and the study offers the first evidence that they traveled vast distances. An outline of the mammoth’s life is detailed in the new issue of the journal Science. [Read more…] about Study takes unprecedented peek into life of 17,000-year-old mammoth
