Self-Healing Pipelines

Circa 2006

Fixing leaking pipelines can be tricky and expensive. But now engineers at a company in Aberdeen, Scotland, have developed a novel way to get the job done. It involves using artificial platelets inspired by the way our blood clots when we get cut.

The platelets, actually small pieces of polymeric or elastomeric material, are introduced into the pipeline upstream and use the flow of the fluid to carry them down the pipe toward the leak. There the pressure forcing the fluid out of the leak causes the platelets to amass at the point of rupture, clogging up the escaping fluid in the process, says Klaire Evans, sales and marketing engineer with Brinker Technology, which is developing the technology.

The method has been tested on a handful of pipelines owned by BP and Shell. According to Sandy Meldrum, an engineer with BP, in Aberdeen, the technology was used to fix a leak in an undersea water injection pipe at an oil field near the Scottish Shetland Isles. Normally this kind of leak would have to be fixed using remotely operated vehicles, whose operators would place a clamp over the leak. But by using Brinker’s technology, BP saved about $3 million, says Meldrum.

This very common issue could be an early sign of dementia

Advanced stages of dementia typically follow a series of muted symptoms patients might mistake for less serious conditions, like stress or sleep deprivation. In fact, according to a new study conducted by researchers from Duke University, many of us evidence one of the premiere red flags associated with the illness almost every day.

“There has been a misperception that financial difficulty may occur only in the late stages of dementia, but this can happen early, and the changes can be subtle,” explained senior author P. Murali Doraiswamy, MBBS, a professor of psychiatry and geriatrics at Duke University, in a media release.

The new paper, published in The Journal of Prevention of Alzheimer’s Disease, examines the cross-sectional relationship between dementia and financial management skills in the elderly. The strength of the report’s findings highlights how limited the diagnostic scope has been up until very recently.

Religious beliefs shape our thinking on cloning, stem cells and gene editing

Christian views tend to be more prohibitive compared with other religions.

It is difficult to examine society’s acceptance or rejection of key biotech developments without considering the role played by the world’s major religions and their belief structures.

Christianity, Judaism, Hinduism, Buddhism and Islam react to new technologies and concepts in their own way – though there is rarely universal consensus on every issue within those religions. Not surprisingly, the basis for modern day beliefs is often found in scripture and related lore.

To better understand, for example, how religions view the use of human embryonic tissue for research and treatment, consider the ancient Jewish tales of golemim — super beings created by humans for protection and tasks.

A single high dose of psilocybin alters brain function up to one month later

New research provides evidence that the active ingredient in so-called magic mushrooms can affect brain processes related to emotional functioning long after the substance has left one’s body. The findings, published in Scientific Reports, shed new light on the long-term effects of psilocybin.

Rather than examining the brain while it’s under the influence of psilocybin, the researchers from Johns Hopkins University School of Medicine were interested in the enduring impact of the substance.

“Nearly all psychedelic imaging studies have been conducted during acute effects of psychedelic drugs. While acute effects of psychedelics on the brain are of course incredibly interesting, the enduring effects of psychedelic drugs on brain function have great untapped value in helping us to understand more about the brain, affect, and the treatment of psychiatric disorders,” said Frederick S. Barrett (@FredBarrettPhD), an assistant professor and the corresponding author of the study.

Military gives COVID patients chloroquine and surges assets to New York City

The malaria medication unproven as a remedy for coronavirus sufferers is being given to sickened troops, Joint Staff Surgeon Air Force Brig. Gen. Paul Friedrichs said at the Pentagon Monday, adding that New York City still faces the biggest threat from the virus.

“The projections are proving not to be all that accurate,” he said, noting Defense Secretary Mark Esper had authorized use of the hospital ship USNS Comfort to take on COVID patients in its limited intensive care spaces.

Defense Department spokesman Jonathan Hoffman added: “DoD continues to surge assets to New York in preparation for the worst.”

Coronavirus: Israeli researchers design low-cost open-source ventilator

Is a low-cost Israeli #ventilator the key to saving #coronavirus patients in #Iran, Africa and more?

“We are not talking about a website for the general public, we are talking about engineers and other experts, and we know the groups who are working on it because they are in touch with us via WhatsApp and emails, to ask questions and understand how to proceed,” he said.

“AmboVent” is a device inspired by the bag-valve mask ventilators that paramedics use when they’re manually ventilating patients in an ambulance, which also offers controls for respiration rate, volume, and maximum peak pressure. Organizations involved in its development include the Magen David Adom, Israeli Air Force 108 Electronics Depot; physicians from Hadassah and Tel Aviv Sourasky medical centers; Microsoft; Rafael, an Israeli defense contractor; Israeli Aerospace Industries; and mentors and students from FIRST Israel, a student robotics organization.

A key feature of the project is that not only the technology is opensource, but its components can be easily built with limited tools and parts, for example 3D printers and car pieces, making the production much more accessible even in less developed country.

“We kept the design and every aspect of it very simple so it would be as easy as possible to be replicated from everywhere,” he said.

Robots replace Japanese students at graduation amid coronavirus

Welcome to the twilight zone.

TOKYO (Reuters) — Spring graduation ceremonies in Japan have been cancelled because of the coronavirus pandemic, but students at one school were able to attend remotely by controlling avatar robots while logged on at home.

The robots, dubbed “Newme” by developer ANA Holdings, were dressed in graduation caps and gowns for the ceremony at the Business Breakthrough University in Tokyo.

The robots’ “faces” were tablets that displayed the faces of the graduates, who logged on at home and controlled the robots via their laptops.
