Incheon’s World Aviation Conference watched by 27,000 viewers on YouTube

May 2, 2021

Aviation leaders from across the globe and an impressive 27,000 viewers virtually watched the recent World Aviation Conference (WAC) in South Korea, hosted by Incheon International Airport Corporation (IIAC).

This year’s event was staged a few weeks ahead of the upcoming 20th anniversary of Incheon International Airport, which within five years of its opening was firmly established as one of the world’s leading hubs and a customer service champion.

Thomas Frey, founder and executive director of the Davinci Institute, joined in a special session titled ‘Recalibrating the aviation industry for the coming era of dramatic change’, where he noted that “COVID-19 had accelerated the adaptation of technologies into our daily lives which would have taken long time otherwise.”

He described the introduction of new transportation technologies such as drones, digital twins and autonomous vehicles as a new “sunrise period”.

This flying electric ferry could revolutionize coastal travel

May 2, 2021

By Trevor Mogg

Imagine living in a coastal community and heading to the harbor for an ultra-low-altitude flight aboard an electric aircraft to a neighboring town just along the water.

Boston-based startup Regent is already working toward such a reality with its 10-passenger “seaglider” that it says could be carrying paying passengers as early as 2025.

Co-founders CEO Billy Thalheimer and CTO Michael Klinker, both of whom previously worked for a Boeing-linked company, told CNBC this week that the zero-emissions plane would begin a journey by leaving a harbor on a hydrofoil before lifting off the water to reach speeds of up to 180 mph — way faster than a lumbering ferry plying the same waters.

ZURICH (Reuters) – Barney is a bit different from your usual Swiss bartender. He is fully automated, mixes dozens of cocktails and even makes terrible jokes.

Developer F & P Robotics says it is seeing rising interest in “The Barney Bar” and hopes it will be a hit among hotels, bars and shopping centres looking to reduce human contact during and after the coronavirus pandemic.

Barney can mix 16 different spirits and eight different sodas for customers who place their orders via their mobile phones, as well as offering beer and prosecco. The robot, who can disinfect his own robotic arm, tells them their drink is ready via a large video display above the bar.

A barista version making different coffees has also been developed. Both versions can be loaded up with conversations, so Barney can make “jokes” about being offered a role in the latest Terminator film, for example.

“We are getting quite a bit of interest,” Chief Sales Officer Gery Colombo told Reuters. “We think Barney can be a fun attraction, that can bring people to a bar because he’s constantly moving and is so different.”

The idea of implantable sensors that continuously transmit information on vital values and concentrations of substances or drugs in the body has fascinated physicians and scientists for a long time. Such sensors enable the constant monitoring of disease progression and therapeutic success. However, until now, implantable sensors have not been suitable to remain in the body permanently and require replacement after a few days or weeks.

There is also the problem of implant rejection as the immune system recognizes the sensor as a foreign object. With many technologies, the sensor’s color, which indicates concentration changes, is unstable and fades over time. Scientists at Johannes Gutenberg University Mainz (JGU) have developed a novel type of implantable sensor that can be implanted in the body for several months. The sensor is based on color-stable gold nanoparticles that are modified with receptors for specific molecules. Embedded into an artificial polymeric tissue, the nanogold is implanted under the skin, where it reports changes in drug concentrations by changing its color.

Professor Carsten Soennichsen’s research group at JGU has been using gold nanoparticles as sensors to detect tiny amounts of proteins in microscopic flow cells for many years. Gold nanoparticles act as small antennas for light: They strongly absorb and scatter it, and appear colorful. They react to alterations in their surrounding by changing color. Soennichsen’s team has exploited this concept for implanted medical sensing.

Researchers Develop A Technique To Produce Transplantable Livers In The Laboratory

May 1, 2021

Researchers at the Human Genome and Stem Cell Research Center (HUG-CELL), hosted by the University of São Paulo’s Institute of Biosciences (IB-USP) in Brazil, have developed a technique to reconstruct and produce livers in the laboratory.

The proof-of-concept study was conducted with rat livers. In the next stage of their research, the scientists will adapt the technique for the production of human livers in order in future to increase the supply of these organs for transplantation.

The study was supported by FAPESP and is reported in an article published in Materials Science and Engineering: C. “The plan is to produce human livers in the laboratory to scale. This will avoid having to wait a long time for a compatible donor and reduce the risk of rejection of the transplanted organ,” Luiz Carlos de Caires-Júnior, first author of the article, told Agência FAPESP. He is a postdoctoral fellow of HUG-CELL, one of the Research, Innovation and Dissemination Centers (RIDCs) funded by FAPESP.

The methodology is based on decellularization and recellularization, tissue bioengineering techniques developed in recent years to produce organs for transplantation. An organ from a deceased donor, in this case the liver, is treated with various solutions containing detergents or enzymes to remove all the cells from the tissue, leaving only the extracellular matrix with the organ’s original structure and shape. The extracellular matrix is then seeded with cells taken from the patient. The technique avoids immune system reactions and the risk of rejection in the long term.

Use of hydrogels in novel stereolithography process eyed for fabricating viable tissues for transplants and other biomedical applications.

By Elizabeth Montalbano

The Holy Grail of 3D bioprinting is to one day be able to fabricate full-sized human organs and tissues to replace the real thing in cases of transplant surgeries and other biomedical applications.

Researchers at the University at Buffalo have made a significant step not only to achieve this endeavor but to do it quickly. A team of researchers there has developed 3D-printing technology that has demonstrated rapid printing of life-sized organs and limbs such as a human hand in less than 20 minutes.

The team—co-led by Ruogang Zhao, associate professor of biomedical engineering, and Chi Zhou, associate professor of industrial and systems engineering—created a 3D-printing method based on stereolithography that uses hydrogels to produce organs quickly. Hydrogels are materials comprised mainly of water that are already used to produce contact lenses and diapers as well as in other applications.

“Our method allows for the rapid printing of centimeter-sized hydrogel models” that “signiﬁcantly reduces part deformation and cellular injuries caused by the prolonged exposure to the environmental stresses you commonly see in conventional 3D printing methods,” Zhou said in a press statement.

The Bank of England and the UK’s Treasury have launched a task force to explore the use of a national digital currency, the British government announced in several press releases early Monday as part of April 2021 Fintech Week.

The task force, formally known as the Central Bank Digital Currency (CBDC) Taskforce, will examine the pros and cons of issuing a new digital form of money that could be used by British consumers alongside cash. But the government is quick to note it hasn’t yet reached a final decision about issuing a digital currency that would potentially compete with cryptocurrencies like bitcoin and ether.

The British government and Bank of England laid out four primary points of interest and goals for the task force, including:

Coordinate exploration of the objectives, use cases, opportunities and risks of a potential UK CBDC.
Guide evaluation of the design features a CBDC must display to achieve our goals.
Support a rigorous, coherent and comprehensive assessment of the overall case for a UK CBDC.
Monitor international CBDC developments to ensure the UK remains at the forefront of global innovation.

The new task force will be led by the Deputy Governor for Financial Stability at the Bank of England, Jon Cunliffe, and HM Treasury’s Director General of Financial Services, Katharine Braddick, according to a press release.

First Prescription Video Game Receives FDA Approval–A Post-COVID Treatment for Persons with ADHD

April 30, 2021

PRESCRIPTION VIDEO GAME AS ADHD TREATMENT?

By Joen Coronel

You won’t believe that health experts have been exploring the capabilities of a video game to contribute to the patients’ well-being during post-COVID-19 treatment. Recovering from the disease might seem to be a long way especially since other people are found to have difficulty in doing their usual tasks.

Even so, symptoms can still linger for some time, and they have not coped up with them for a while.

The first video game to have been approved by the Food and Drug Administration (FDA) as a treatment for children with ADHD is now out for playing. Particularly, it targets those whose ages range from eight to twelve years old.

The video game called “EndeavorRX” was developed by Akili Interactive last summer when it passed as an official prescription. New York-based neuropsychologist, Faith Gunning thought of this recreation to work similarly to the usual treatment for the symptoms.

However, Gunning not only considered the certain bracket to benefit from playing it, but he also noted that it could also help other people who are not in the same group. It began when she has seen that those COVID-19 patients need something to cope up with their symptoms.

Russia is building its own space station to launch in 2025 amid concerns the ISS is becoming too unreliable and ‘endangers the life of the crew’

April 29, 2021

By Ryan Morrison and Will Stewart

The Russian space agency Roscosmos declared the ISS unsafe and a risk to life
They are launching a new station within the next four years in low Earth orbit
This includes a ‘tourist’ module with room for up to four visitors from the Earth
It comes amid increasing tensions between Russia and the West

Russia could withdraw from the International Space Station in 2025 and launch its own facility over concerns the ISS is becoming too unreliable, Roscosmos says.
Dmitry Rogozin, chief of the Russian space agency said work has already begun on the first module of a new station, expected to go into orbit early in 2025.

A top Kremlin official warned that ‘disaster’ was looming for the ISS, putting the lives of crew members at risk due to its age – by 2025 is will be 27 years old and was originally designed to last between 15 and 30 years, according to NASA.

Cerebras launches new AI supercomputing processor with 2.6 trillion transistors

April 29, 2021

By Dean Takahashi

Cerebras Systems has unveiled its new Wafer Scale Engine 2 processor with a record-setting 2.6 trillion transistors and 850,000 AI-optimized cores. It’s built for supercomputing tasks, and it’s the second time since 2019 that Los Altos, California-based Cerebras has unveiled a chip that is basically an entire wafer.

Chipmakers normally slice a wafer from a 12-inch-diameter ingot of silicon to process in a chip factory. Once processed, the wafer is sliced into hundreds of separate chips that can be used in electronic hardware.

But Cerebras, started by SeaMicro founder Andrew Feldman, takes that wafer and makes a single, massive chip out of it. Each piece of the chip, dubbed a core, is interconnected in a sophisticated way to other cores. The interconnections are designed to keep all the cores functioning at high speeds so the transistors can work together as one.

A newly discovered 3D-printing method could be revolutionary for bone cancer treatment.

By Douglas Broom

How can patients recover from surgery that removes parts of their bones?
Up to now the answer has been to build a ceramic replica in a laboratory.
But now scientists have invented a way to 3D-print bone tissue inside the body.
Ceramic material that mimics bone structure is mixed with living cells.
Its inventors say it will reduce suffering and speed up recovery.

A new 3D printing process which can be used inside the human body is offering hope to trauma and cancer patients who need bone replacements, reducing pain and speeding up recovery time.

The treatment of bone cancers can lead to sections of bone being removed and accident victims may require extensive bone repairs. Up to now, 3D bone printing has involved producing material outside the patient’s body.

But now a new technique developed at the University of New South Wales in Sydney, Australia, offers the prospect of doctors being able to create new bone tissue exactly where it is needed during a surgical operation.
