L.E.D. Pioneer Akasaki’s “Perseverance — Sheer Doggedness — Paid Off”

(p. B10) Isamu Akasaki, a Japanese physicist who helped develop blue light-emitting diodes, a breakthrough in the development of LEDs that earned him a Nobel Prize and transformed the way the world is illuminated, died on Thursday [April 1, 2021] in a hospital in Nagoya, Japan. He was 92.

. . .

Bob Johnstone, a technology journalist and the author of “L.E.D.: A History of the Future of Lighting” (2017), said in an email, “The prevailing opinion in the late 1980s was that, because of the number of flaws in the crystal structure of gallium nitride, it would never be possible to make light-emitting diodes from it, so why would you even try?”

Dr. Akasaki, he continued, “was willing to stick at what was almost universally recognized to be a lost cause, working away long after researchers at RCA and other U.S. pioneers of gallium nitride LED technology had given up.”

“Eventually,” Mr. Johnstone said, “his perseverance — sheer doggedness — paid off.”

. . .

Dr. Akasaki was awarded hundreds of patents for his research over the years, and the royalties from his groundbreaking work with Dr. Amano eventually funded the building of a new research institute, the Nagoya University Akasaki Institute, completed in 2006.

. . .

When asked in a 2016 interview with the Electrochemical Society to summarize the philosophy guiding his many years of single-minded research, Dr. Akasaki replied, “No pain, no gain.”

“I say this to younger people: Experience is the best teacher,” he continued. “That is, sometimes there is no royal road to learning.”

A Cheap Nonrefrigerated Drug that Could Have Saved Tens of Thousands of Women’s Lives Languished for Half a Century Waiting for a Clinical Trial

They already knew tranexamic saved lives of bleeding soldiers and bleeding car crash victims. Why did regulators make the world wait 50 years, and finally do an expensive randomized double-blind clinical trial, to know that it also would save the lives of bleeding new mothers? You can’t blame drug companies. The drug’s patent had expired long ago, so no drug company would make profits from the sale of the drug sufficient to pay the expense of the clinical trial.

(p. D3) An inexpensive generic drug that saves the lives of wounded soldiers and civilian car crash victims has now been shown to rescue women suffering hemorrhages in childbirth.

. . .

In a major six-year trial involving over 20,000 women in 21 countries, researchers showed that tranexamic acid, a little-known blood-clotter invented in the 1950s, reduced maternal bleeding deaths by a third if it was given within three hours. It costs less than $2 a dose and does not require refrigeration.

The trial — known as Woman, short for World Maternal Antifibrinolytic — was led by doctors at the London School of Hygiene and Tropical Medicine and paid for by the Wellcome Trust, Pfizer, Britain’s health department and the Bill and Melinda Gates Foundation. Results were published in The Lancet on Wednesday [April 26, 2017].

. . .

The World Health Organization currently recommends treating birth hemorrhages by massaging the uterus and injecting uterus-shrinking drugs like oxytocin.

Tranexamic acid acts in a different way — it allows blood to clot more quickly — and so it should be given in addition to the usual measures and at the same time, said Dr. Ian Roberts, one of the study’s lead authors.

. . .

The drug was invented in Japan by a husband-wife research team, Shosuke and Utako Okamoto. They hoped it would be used to prevent birth hemorrhages, but local obstetricians declined to organize a clinical trial.

Ultimately, they turned the patent over to a Japanese pharmaceutical company, which sold it as treatment for heavy menstrual periods and as an ingredient in skin-whitening creams. Some oral surgeons used it when doing dental work on hemophiliacs, Dr. Roberts said.

Tranexamic Acid (TXA) History

Scientists Invest Much Money and Time to Develop Machines Able to Sniff as Well as a Dog

Seven years have passed since the article quoted below predicted that sniffing devices would be available to clinicians in three to five years. I believe the prediction was premature. In the meantime, we should be making more and better use of dog noses to sniff out disease.

(p. D5) But not every physician’s nose is a precision instrument, and dogs, while adept at sniffing out cancer, get distracted. So researchers have been trying for decades to figure out how to build an inexpensive odor sensor for quick, reliable and noninvasive diagnoses.

. . .

“You’re seeing a convergence of technology now, so we can actually run large-scale clinical studies to get the data to prove odor analysis has real utility,” said Billy Boyle, co-founder and president of operations at Owlstone, a manufacturer of chemical sensors in Cambridge, England.

Mr. Boyle, an electronics engineer, formed the company with two friends in 2004 to develop sensors to detect chemical weapons and explosives for customers, including the United States government. But when Mr. Boyle’s girlfriend and eventual wife, Kate Gross, was diagnosed with colon cancer in 2012, his focus shifted to medical sensors, with an emphasis on cancer detection.

Ms. Gross died at the end of 2014. That she might still be alive if her cancer had been detected earlier, Mr. Boyle said, continues to be a “big motivator.”

. . .

A similar diagnostic technology is being developed by an Israeli chemical engineer, Hossam Haick, who was also touched by cancer.

“My college roommate had leukemia, and it made me want to see whether a sensor could be used for treatment,” said Mr. Haick, a professor at Technion-Israel Institute of Technology in Haifa. “But then I realized early diagnosis could be as important as treatment itself.”

. . .

In the United States, a team of researchers from the Monell Chemical Senses Center and the University of Pennsylvania received an $815,000 grant in February [2017] from the Kleberg Foundation to advance work on a prototype odor sensor that detects ovarian cancer in samples of blood plasma.

. . .

“We are trying to make the device work the way we understand mammalian olfaction works,” said Charlie Johnson, director of the Nano/Bio Interface Center at the University of Pennsylvania, who is leading the fabrication effort. “DNA gives unique characteristics for this process.”

In addition to these groups, teams in Austria, Switzerland and Japan also are developing odor sensors to diagnose disease.

“I think the fact that you’re seeing so much activity both in commercial and academic settings shows that we’re getting a lot closer,” said Cristina Davis, a biomedical engineer and professor at the University of California, Davis, who also is helping to develop an odor sensor to diagnose disease.

“My estimate is it’s a three- to five-year time frame” before such tools are available to clinicians, she added.

“Everyone Just Exchanges Platitudes and Inanities Because They Are Afraid to Say Anything”

(p. B3) The younger generation has frequently called out Japan’s entrenched elders for their casual sexism, excessive work expectations and unwillingness to give up power.

But a surprise television hit has people talking about whether the oldsters might have gotten a few things right, especially as some in Japan — like their counterparts in the United States and Europe — question the heightened sensitivities associated with “wokeness.”

The show, “Extremely Inappropriate!,” features a foul-talking, crotchety physical education teacher and widowed father who boards a public bus in 1986 Japan and finds himself whisked to 2024.

. . .

The show was one of the country’s most popular when its 10 episodes aired at the beginning of the year on TBS, one of Japan’s main television networks. It is also streaming on Netflix, where it spent four weeks as the platform’s No. 1 show in Japan.

. . .

Not so subtly, the show . . . comments on the evolution toward more inclusive and accommodating offices, caricaturing them as places where work is left undone because of strict overtime rules and employees apologize repeatedly for running afoul of “compliance rules.”

Such portrayals strike a chord in Japan, where there have been complaints, often expressed on social media, about “political correctness” being used as a “club” to restrict expression or to water down television programs or films. Part of what fans have found refreshing about “Extremely Inappropriate!” is how unrestrained the portions set in the Showa era are.

While critics have called the series retrograde, some younger viewers say the show has made them question social norms they once took for granted — and wonder about what has been lost.

Writing for an entertainment-oriented Web publication, Rio Otozuki, 25, said that the series “must have left many viewers thinking inwardly that the Showa era was more fun.”

. . .

Kaori Shoji, an arts critic who was a teenager in the 1980s, said she loved “Extremely Inappropriate!” She particularly appreciated how the series illuminated the chilling effects of today’s tighter policing of workplaces.

“Everyone is just playing a game to see who can be the least offensive person that ever walked the earth,” Ms. Shoji said. “Everyone just exchanges platitudes and inanities because they are afraid to say anything. Surely that cannot be good for a workplace.”

In Australia and Japan “Coral Appear to Be Migrating Poleward”

(p. A9) Scientists are still learning about corals’ ability to adapt to climate change. Efforts are underway to breed coral that tolerate higher temperatures. In a few places, including Australia and Japan, coral appear to be migrating poleward, beginning to occupy new places.

Mandated Fukushima Evacuations Killed 1,600; Radiation Killed 0

Berkeley scientist Noah Whiteman’s Most Delicious Poison argues that often chemicals that are therapeutic at low doses are poisons at high doses. The commentary quoted below provides evidence that what Whiteman argues is true of many chemicals, is also true of radiation.

(p. D3) This spring [2015], four years after the nuclear accident at Fukushima, a small group of scientists met in Tokyo to evaluate the deadly aftermath.

No one has been killed or sickened by the radiation — a point confirmed last month by the International Atomic Energy Agency. Even among Fukushima workers, the number of additional cancer cases in coming years is expected to be so low as to be undetectable, a blip impossible to discern against the statistical background noise.

But about 1,600 people died from the stress of the evacuation — one that some scientists believe was not justified by the relatively moderate radiation levels at the Japanese nuclear plant.

. . .

“The government basically panicked,” said Dr. Mohan Doss, a medical physicist who spoke at the Tokyo meeting, when I called him at his office at Fox Chase Cancer Center in Philadelphia. “When you evacuate a hospital intensive care unit, you cannot take patients to a high school and expect them to survive.”

Among other victims were residents of nursing homes. And there were the suicides. “It was the fear of radiation that ended up killing people,” he said.

Most of the fallout was swept out to sea by easterly winds, and the rest was dispersed and diluted over the land. Had the evacuees stayed home, their cumulative exposure over four years, in the most intensely radioactive locations, would have been about 70 millisieverts — roughly comparable to receiving a high-resolution whole-body diagnostic scan each year. But those hot spots were anomalies.

By Dr. Doss’s calculations, most residents would have received much less, about 4 millisieverts a year. The average annual exposure from the natural background radiation of the earth is 2.4 millisieverts.

How the added effect of the fallout would have compared with that of the evacuation depends on the validity of the “linear no-threshold model,” which assumes that any amount of radiation, no matter how small, causes some harm.

Dr. Doss is among scientists who question that supposition, one built into the world’s radiation standards. Below a certain threshold, they argue, low doses are harmless and possibly even beneficial — a long-debated phenomenon called radiation hormesis.

. . .

Life evolved in a mildly radioactive environment, and some laboratory experiments and animal studies indicate that low exposures unleash protective antioxidants and stimulate the immune system, conceivably protecting against cancers of all kinds.

. . .

. . ., a study of radon by a Johns Hopkins scientist suggested that people living with higher concentrations of the radioactive gas had correspondingly lower rates of lung cancer. If so, then homeowners investing in radon mitigation to meet federal safety standards may be slightly increasing their cancer risk. These and similar findings have also been disputed.

. . .

There is more here at stake than agonizing over irreversible acts, like the evacuation of Fukushima. Fear of radiation, even when diluted to homeopathic portions, compels people to forgo lifesaving diagnostic tests and radiotherapies.

We’re bad at balancing risks, we humans, and we live in a world of continual uncertainty. Trying to avoid the horrors we imagine, we risk creating ones that are real.

Firms Develop Technology to Capture, Liquify, Transport, and Sequester CO2 into “Depleted Offshore Oil-and-Gas Wells”

(p. B4) ATHENS—Ship operators have a radical idea for industrial companies that are searching for ways to dispose of carbon emissions: Take the captured CO2 out to sea and bury it deep under the ocean floor.

But first, supercool the carbon emissions to temperatures so low that they become a liquid.

HD Hyundai Heavy Industries, the world’s largest shipyard, and Greece-based shipowner Capital Product Partners have designed a specialized vessel to carry liquefied CO2. They envision such ships transporting their cargo to depleted offshore oil-and-gas wells, where it would be pumped in and entombed for permanent storage. Capital Product Partners signed a deal for four such ships, to be delivered in 2025 and 2026, that together cost more than $300 million.

“Ships move everything from oil to our furniture, clothes and toothpaste. Now they’ll move our emissions, which is in effect waste management,” said Jerry Kalogiratos, chief executive of U.S.-listed Capital Product Partners, which operates more than 100 cargo vessels.

. . .

“The wells are sealed with a fast drying mix of concrete and sand. If there is a leak inland the gas could end up back in the atmosphere, but there is no conclusive research about what will happen if it escapes in the water,” said Fotis Pagoulatos, a naval engineer in Athens. “The consensus for now is that pollution risk at sea from leaked CO2 is low.”

. . .

While no contracts have been signed, Kalogiratos said Capital Product Partners is in talks with a number of European emitters as well as big energy companies in Japan and South Korea.

For Quick Spread of EVs, U.S. Regulators Need to Quickly Approve More Domestic Mines for Critical Minerals

(p. A6) For decades, a group of the world’s biggest oil producers has held huge sway over the American economy and the popularity of U.S. presidents through its control of the global oil supply, with decisions by the Organization of the Petroleum Exporting Countries determining what U.S. consumers pay at the pump.

As the world shifts to cleaner sources of energy, control over the materials needed to power that transition is still up for grabs.

China currently dominates global processing of the critical minerals that are now in high demand to make batteries for electric vehicles and renewable energy storage. In an attempt to gain more power over that supply chain, U.S. officials have begun negotiating a series of agreements with other countries to expand America’s access to important minerals like lithium, cobalt, nickel and graphite.

But it remains unclear which of these partnerships will succeed, or if they will be able to generate anything close to the supply of minerals the United States is projected to need for a wide array of products, including electric cars and batteries for storing solar power.

Leaders of Japan, Europe and other advanced nations, who are meeting in Hiroshima, agree that the world’s reliance on China for more than 80 percent of processing of minerals leaves their nations vulnerable to political pressure from Beijing, which has a history of weaponizing supply chains in times of conflict.

. . .

. . ., some U.S. officials argue that the supply of critical minerals in wealthy countries with high labor and environmental standards will be insufficient to meet demand, . . .

. . .

Jennifer Harris, a former Biden White House official who worked on critical mineral strategy, argued that the country should move more quickly to develop and permit domestic mines, . . .

. . .

“There’s so much that needs doing that this is very much a ‘both/and’ world,” she said. “The challenge is that we need to responsibly pull up a whole lot more rocks out of the ground yesterday.”

“In Tokyo Good Things Have Been Created Through Private Initiative”

(p. A22) Yuta Yamasaki and his wife moved from southern Japan to Tokyo a decade ago because job prospects were better in the big city. They now have three sons — ages 10, 8 and 6 — and they are looking for a larger place to live. But Mr. Yamasaki, who runs a gelato shop, and his wife, a child-care worker, aren’t planning to move far. They are confident they can find an affordable three-bedroom apartment in their own neighborhood.

As housing prices have soared in major cities across the United States and throughout much of the developed world, it has become normal for people to move away from the places with the strongest economies and best jobs because those places are unaffordable. Prosperous cities increasingly operate like private clubs, auctioning off a limited number of homes to the highest bidders.

Tokyo is different.

. . .

Small apartment buildings can be built almost anywhere, and larger structures are allowed on a vast majority of urban land. Even in areas designated for offices, homes are permitted. After Tokyo’s office market crashed in the 1990s, developers started building apartments on land they had purchased for office buildings.

“In progressive cities we are maybe too critical of private initiative,” said Christian Dimmer, an urban studies professor at Waseda University and a longtime Tokyo resident. “I don’t want to advocate a neoliberal perspective, but in Tokyo good things have been created through private initiative.”

Tokyo makes little effort to preserve old homes. Historic districts subject to preservation laws exist in other Japanese cities, but the nation’s largest city has none. New construction is prized. People treat homes like cars: They want the latest models.

Okinawans Think Ikigai (a Reason for Living) Is Important for Long Life

(p. A11) Ask most people if they want to live to be 100 and the response is likely to be “Sure!” followed by “Wait a sec . . .” Questions suddenly abound: Am I going to be healthy? Am I going to be lonely? Will I be financially stable? Will I have outlived everyone I knew and loved? What author-researcher Dan Buettner set out to demonstrate in “Live to 100: Secrets of the Blue Zones” is that the solutions to those concerns are also the keys to longevity itself.

. . .

What is clear early on is that what Mr. Buettner “discovers” during his visits to Sardinia; Singapore; Okinawa, Japan; Ikaria, Greece; and even Loma Linda, Calif., is largely what we would expect: that much of what helps people live longer isn’t necessarily the purple Japanese sweet potatoes, or going to church every day, or having the limited stress load of a Greek shepherd. It is an Okinawan diet rich in nutrients and fiber, the walking uphill to the Sardinian church, and the community to which one belongs in Loma Linda when one is, for instance, a Seventh Day Adventist who plays pickleball.

. . .

There are many correlating clues to a longer life across the locations in “Live to 100.” Okinawans emphasize the importance of having an ikigai, or reason for living; in Costa Rica the same thing is called one’s plan de vida.

Feds Impose Tariffs on Imports of Paper-Thin Steel Needed to Make EV Engines

(p. A3) Large U.S. steelmakers are ramping up production of a hard-to-make, paper-thin steel to capture a fast-growing market for a material critical to powering electric vehicles.

. . .

Such electrical steel, which accounts for about 1% of all the steel produced annually in the world, already is in short supply for electric vehicles, executives said. Companies expect demand to accelerate faster than production as EV volumes expand in the coming years.

“It’s in limited supply and with very long lead times. Sometimes 50 or 52 weeks,” said Hale Foote, owner of Scandic Springs Inc., a San Leandro, Calif., company that uses high-grade electrical steel to make parts for scientific measurement devices.

. . .

More than 80% of the electrical steel produced comes from China, Japan and South Korea, all countries that are subject to U.S. tariffs or quotas on steel imports, industry analysts said.

. . .

(p. B2) “It takes intense focus. You have to have absolute consistency or you scrap the material,” said David Stickler, who led the investment group that built Big River Steel in Osceola, Ark., and then sold the mill to U.S. Steel in 2021. Mr. Stickler said he envisioned electrical steel being a core product at Big River when he started planning the mill nearly a decade ago.

. . .

Steel-industry executives said that creating more domestic capacity to make electrical steel for vehicles will likely take years, as steel companies acquire equipment and become proficient at the exacting production process.

“You can’t just buy the equipment and start making electrical steel. Those who’ve made the investment will have an advantage for the next five to 10 years,” Mr. Stickler said.
