Versius receives ‘indication’ extended into thoracic surgery

January 25, 2022 by Editor Leave a Comment

CMR Surgical says its Versius Surgical Robotic System has been “indicated” for thoracics to support surgeons providing minimally invasive surgery to patients undergoing operations in the lungs, thymus and oesophagus.

In medicine, an “indication” is a valid reason to use a certain test, medication, procedure, or surgery.

Following a gradual introduction with specific case and procedure selection, Versius has now been used in both major and minor cases including oesophagomyotomies, lobectomies and thymectomies. [Read more…] about Versius receives ‘indication’ extended into thoracic surgery

Small ship takes part in UK’s first hydrogen transport trials

January 21, 2022 by Editor Leave a Comment

A consortium of partners has unveiled the UK’s first demonstration of zero-emission marine technology in the Tees Valley, in north England.

In a bid to show the path available for the maritime sector to decarbonise, the demonstration will convert a Lochin 33 “workboat” into a dual-fuelled vessel acting as a testbed to prove the concept of a retro-fit green hydrogen solution.

For the purposes of the demonstration, the modified marine vessel will operate at sea, though the technologies are suitable for use by inland waterway vessels. The project is expected to take seven months, with trials running in Spring 2022. [Read more…] about Small ship takes part in UK’s first hydrogen transport trials

Is it cheaper to be bigger? Lessons from the extreme weapons of giraffe weevil warriors

August 18, 2021 by Editor

Nepalese craftsman, Chandra Bahadur Dangi, holds the record as the world’s shortest adult, at 54.6 cm (1 ft 9 ½ inches). The tallest human is Sultan Kösen, a Turkish farmer, almost five times taller at 2.52 meters (8 feet 3 ¼ inches).

In nature, size differences among males of a single species are not uncommon, but in a new paper, a team from the Smithsonian Tropical Research Institute (STRI), The University of Auckland and the University of Arizona, discovered a case of male beetles that are not only extremely different in size, but also provide an answer to long-standing puzzle in evolutionary biology: how can larger animals afford the energetic cost of making and maintaining disproportionately large weapons?

Almost one in every four species in the world is a beetle: about 350,000 beetle species have been identified so far. Male New Zealand giraffe weevils, Lasiorhynchus barbicornis, were known to be the longest beetles in the world, but when researchers measured the differences in the weight of the smallest and largest beetles, they were in for a surprise.

Calling all couch potatoes: This finger wrap can let you power electronics while you sleep

July 26, 2021 by Editor

A new wearable device turns the touch of a finger into a source of power for small electronics and sensors. Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it.

What’s special about this sweat-fueled device is that it generates power even while the wearer is asleep or sitting still. This is potentially a big deal for the field of wearables because researchers have now figured out how to harness the energy that can be extracted from human sweat even when a person is not moving.

This type of device is the first of its kind, said co-first author Lu Yin, a nanoengineering Ph.D. student at the UC San Diego Jacobs School of Engineering. “Unlike other sweat-powered wearables, this one requires no exercise, no physical input from the wearer in order to be useful. This work is a step forward to making wearables more practical, convenient and accessible for the everyday person.” [Read more…] about Calling all couch potatoes: This finger wrap can let you power electronics while you sleep

Columbia Engineering team builds first hacker-resistant cloud software system

May 26, 2021 by Editor

Whenever you buy something on Amazon, your customer data is automatically updated and stored on thousands of virtual machines in the cloud.

For businesses like Amazon, ensuring the safety and security of the data of its millions of customers is essential. This is true for large and small organizations alike. But up to now, there has been no way to guarantee that a software system is secure from bugs, hackers, and vulnerabilities.

Columbia Engineering researchers may have solved this security issue. They have developed SeKVM, the first system that guarantees – through a mathematical proof – the security of virtual machines in the cloud. In a new paper to be presented on May 26, 2021, at the 42nd IEEE Symposium on Security & Privacy, the researchers hope to lay the foundation for future innovations in system software verification, leading to a new generation of cyber-resilient system software.

Small galaxies likely played important role in evolution of the Universe

May 3, 2021 by Editor

A new study led by University of Minnesota astrophysicists shows that high-energy light from small galaxies may have played a key role in the early evolution of the Universe.

The research gives insight into how the Universe became reionized, a problem that astronomers have been trying to solve for years.

The research is published in The Astrophysical Journal, a peer-reviewed scientific journal of astrophysics and astronomy. [Read more…] about Small galaxies likely played important role in evolution of the Universe

NIST study suggests how to build a better ‘nanopore’ biosensor

May 1, 2021 by Editor

Researchers have spent more than three decades developing and studying miniature biosensors that can identify single molecules.

In five to 10 years, when such devices may become a staple in doctors’ offices, they could detect molecular markers for cancer and other diseases and assess the effectiveness of drug treatment to fight those illnesses.

To help make that happen and to boost the accuracy and speed of these measurements, scientists must find ways to better understand how molecules interact with these sensors. [Read more…] about NIST study suggests how to build a better ‘nanopore’ biosensor

Raindrops also keep fallin’ on exoplanets

April 9, 2021 by Editor

One day, humankind may step foot on another habitable planet. That planet may look very different from Earth, but one thing will feel familiar – the rain.

In a recent paper, Harvard researchers found that raindrops are remarkably similar across different planetary environments, even planets as drastically different as Earth and Jupiter.

Understanding the behavior of raindrops on other planets is key to not only revealing the ancient climate on planets like Mars but identifying potentially habitable planets outside our solar system. [Read more…] about Raindrops also keep fallin’ on exoplanets

Small cell lung cancer: Scientists identify two new approaches for therapy

April 8, 2021 by Editor

Using samples of small cell lung tumours, a research team led by biologist Dr Silvia von Karstedt has discovered two new ways to induce tumour cell death.

One of two subsets of tumour cells can be targeted by activating ferroptosis: iron-dependent cell death caused by oxidative stress.

In the second subtype, oxidative stress – and hence cell death – can also be induced in a different way.

Both types of cell death must be triggered simultaneously by drugs to kill the majority of the tumour mass. The results of the study have been published in Nature Communications.  [Read more…] about Small cell lung cancer: Scientists identify two new approaches for therapy
