  • A Ghost Fleet of Tankers Is Keeping Russia’s War Machine Afloat. The West Can’t Stop It. "How Putin outsmarted the oil sanctions."
  • Still Haunted by the Edmund Fitzgerald. "50th Anniversary Tribute". Seems appropriate that we are getting our first winter storm on Sunday. 
  •  Google Docs Gets Smarter. "Audio narration, AI help, and 40 new templates." Many of the new features require an AI-enabled plan, but there are some, like document tabs, that could be quite useful for longer documents.
  • The Florentine Diamond Resurfaces After 100 Years in Hiding. "A legendary jewel of the Hapsburg dynasty — not seen since 1919 and thought lost, stolen or recut — has actually been safe in a Canadian bank for decades." This is quite a story. 
  • ‘Frankenstein’: How Close Is Guillermo del Toro’s Film to the Original Novel? A Mary Shelley Expert Answers Our Burning Questions. "So, just how well does del Toro’s version stack up against Mary Shelley’s original novel? We asked Julie Carlson, an English professor at the University of California, Santa Barbara and an expert on the British Romantic period and the Wollstonecraft-Godwin-Shelley family, for her thoughts." I enjoyed the movie, though I did find it hard to watch in places (many very dark scenes). 
  • Find cancer clinical trials in Canada. "Helping people living with cancer and healthcare professionals navigate cancer trial options." It's good that Canadians have an alternative to looking in the US for information. 
  • New laser treatment could stop blindness before it starts. "A new laser treatment may halt dry macular degeneration by using controlled warmth to trigger the eye’s self-repair mechanisms." Of course, it will be years before this becomes widespread, assuming it works. 
  • I’m never going back to Microsoft Word after mastering this open-source self-hosted tool. "Enter HedgeDoc, the open-source web-based collaborative markdown editor that has changed my writing setup. By running it on my server, I achieved true data independence that Word could never offer." Ten or fifteen years ago, I would have jumped on this, but at this point in my life, I just can't be bothered.

    Smart Glasses for Macular Degneration

    If you've read this blog for a while, you'll know that I am very nearsighted. One of the risks of high myopia is macular degeneration, which can result in losing your central field of vision. Since this has the highest resolution of any part of the eye, it results in losing the ability to read, watch television, or recognize faces.

    At CES this year, BoingBoing reports that a small company called Solidddd demonstrated a new technology that might help to restore some vision to people suffering from macular degeneration. They are building smart glasses that project an array of 64 images onto the retina; your brain then combines them into a single, full field image. Initial trials seem to be promising and they hope to have a product release later this year.

    I've embedded the video from the BoingBoing article below. It does seem promising, though still very preliminary.


    It's possible that this might help with any kind of central vision loss. Given that the eye's peripheral vision is lower resolution than the macular area, it probably won't be as sharp as what you would see through an undamaged macula and  it will be limited by the resolution of the cameras they are using. 

    I also don't know how computational requirements of their software. Will it run on glasses alone or will it require an attached unit for the computing and battery like Apple's VisionPro? (Which leads me to wonder if Apple could adapt the VisionPro to work like the Soliddd technology). 

    Still, if it works, it will be a game change for people with central vision loss and I will be following this story closely.

    • A New Kind of Urban Firestorm (gift link). "The blazes that have consumed Altadena and the Los Angeles neighborhood of Pacific Palisades hark back to historic urban firestorms — a kind of disaster that was supposed to have been extinguished by the development of modern fire departments and strong building codes. But decades of development in fire-prone landscapes and rapid planetary warming have sparked another era of urban conflagration, experts say."

    • MAME Devs Spent 628 Years Cracking Protection on 712 Retro Games. "A new study published by data scientists Kristofer Erickson and Felix Rodriguez Perez, in collaboration with the CREATe Centre at the University of Glasgow, considers the effect of Technological Protection Measures (TPM) on video game preservation. The researchers focused on MAME, which to date has successfully emulated over 14,377 legacy devices, including 3,783 arcade machines dating back to 1979."
    • Reading the news. "A new report detailing allegations against Neil Gaiman is a good opportunity to better understand how news works and spreads."

    • 4 Signs Your Google Account Is Hacked – And What To Do. "Gmail is — and has been for years — one of the most popular free email services, with around two billion active users around the world. Access comes via a Google account, which also includes Google Ads, YouTube and Google Play. And because of this, a compromised Google account can give the hackers access to a wide range of data, including emails, documents, photos and even financial details. Using this information, they can scam your contacts with spam, phishing emails or malicious attachments or even extort you. But don't despair: if your Google account is hacked, it's possible to regain it and keep it secure in future."

    The World's Myopia Epidemic

    I've been nearsighted all my life so I tend to take it for granted. But I will agree that it's not a normal condition, in the sense that it's a departure from baseline health. And it is becoming more common, but until I read this article, I hadn't realized just how common. 

    The article focuses (sorry, couldn't resist) on Taiwan, where more than half of children were myopic, and the efforts of one doctor to determine the cause and find a way to prevent it. It turns out that it's possible to reduce the incidence of myopia in children by having them spend more time outdoors and this has been determined to work. 

    Myopia, or what we commonly call nearsightedness, happens when the eyeball gets too long—it deforms from soccer ball to American football—and then the eye focuses light not on the retina but slightly in front of it, making distant objects appear blurry. The longer the eyeball becomes, the worse vision gets. Ophthalmologists measure this distortion in diopters, which refer to the strength of the lens required to bring someone’s vision back to normal. Anything worse than minus 5 diopters is considered “high myopia”—somewhere between 20 and 25 percent of myopia diagnoses around the world are in this category. In China, up to 90 percent of teenagers and young adults are myopic. In the 1950s the figure was as low as 10 percent. A 2012 study in Seoul found that an astonishing 96.5 percent of 19-year-old men were nearsighted. Among high schoolers in Taiwan, it’s around 90 percent. In the US and Europe, myopia rates across all ages are well below 50 percent, but they’ve risen sharply in recent decades. It’s estimated that by 2050, half the world’s population will need glasses, contacts, or surgery to see across a room. High myopia is now the leading cause of blindness in Japan, China, and Taiwan.

    If those trends continue, it’s likely that millions more people around the world will go blind much earlier in life than they—or the societies they live in—are prepared for. It’s a “ticking time bomb,” says Nicola Logan, an optometry professor at the UK’s Aston University. She wasn’t the only expert I talked to who used that phrase. Because so much of Taiwan’s population is already living life with myopia, the island nation has already glimpsed what could be coming for the rest of us. And in a rare confluence, the country may also be the best place to look for solutions.

    Some Science Fictional Medical Advances

    Reading medical news these days is becoming more and more like reading a science fiction novel. Here are some stories that definitely triggered my sensawunda*. 

    • Hibernation for long space journeys has long been a trope of science fiction. Now, researchers have induced hibernation in rats, animals that do not normally hibernate. The technique uses non-invasive targeted ultrasound. 
    • Man with paralysis walks naturally after brain, spine implants. "Dr. Grégoire Courtine and colleagues from the Swiss Federal Institute of Technology in Lausanne developed and implanted a “brain-spine interface” that creates a direct neurological link between the brain and spinal cord. Implants in the brain track intentions for movement, which are wirelessly transferred to a processing unit that a person wears externally, like a backpack. The intentions are translated into commands that the processing unit sends back through the second implant to stimulate muscles. The research findings, published Wednesday in the journal Nature, outline successful outcomes for one study participant from the Netherlands."
    • Scientists use AI to identify new antibiotic that could fight drug-resistant infections. "Using an artificial intelligence algorithm, researchers at MIT and McMaster University have identified a new antibiotic that can kill a type of bacteria that is responsible for many drug-resistant infections. If developed for use in patients, the drug could help to combat Acinetobacter baumannii, a species of bacteria that is often found in hospitals and can lead to pneumonia, meningitis, and other serious infections. The microbe is also a leading cause of infections in wounded soldiers in Iraq and Afghanistan."
    • Gene Therapy Gives Primates Young Eyes Again. "Last month, a team of scientists from Harvard Medical School and biotech company Life Biosciences announced preclinical data showing that a new approach was able to reprogram genetic markers to restore visual function in primates that had their eyes damaged with lasers. In essence, the team injected their eyes with special chemicals that can partially reprogram cells to have them return to a more youthful state."

    *SFnal term meaning sense of wonder.

    Data Tools for Visually Impaired Scientists

    Being visually impaired, I have a keen interest in tools that help people use computers in their work and daily life. I've been fortunate that so far I've been able to cope with just a magnifier and using a large monitor and the tools built into Windows. But what about people doing data analysis and having to cope with screens of data, often in graphic or tabular form?

    Nature has published an article about tools to help visually impaired or blind scientists do data analysis that I found quite interesting. While I don't need anything more complex than bar graphs for my household accounts, I'm glad to see that people are thinking about this problem.

    An online tool called SciA11y, developed by the Allen Institute for Artificial Intelligence (AI2) in Seattle, Washington, uses machine learning to extract the content and structure of a PDF (and other file formats, such as LaTeX) and re-render it in HTML, creating a table of contents containing links to tagged section headings that can be navigated with screen readers. AI2 has also built in functionality such as bidirectional navigation between in-line citations and their corresponding references in the bibliography, says Jonathan Bragg, who co-leads the project.

    In a detailed survey3, six scientists with vision loss described how they frequently found themselves unable to access or read PDFs. One respondent mentioned that they encountered problems two-thirds of the time, and that they use at least six different approaches to read papers. “It was eye-opening to see the range of tools that people use when reading — and the struggles they have when those papers have not been formulated appropriately,” Bragg says.
