Like to charge and reblog to cast Chinese scientists destroying the Insulin industry

Here’s a link with more details! They got an insulin dependent patient medication free in just 11 weeks using a cell transplant! It’s still very early and needs a lot more testing to see if they can replicate the results, but having success in a human is very promising!

Someday in a Trek novel I'll be writing the line about a situation like this. McCoy will shrug and say, "Well, we can handle this a couple of ways. We'll either turn their pancreas back on, or print them a new one." And it won't be SF at all. :)

...He should then add, "So what'll we do after lunch?"

Love that he does not interpret or explain. Sure, we all have Google, but it is funny to have a teachable moment opportunity and to instead go, “nah.”

“A young scientist who worked in the jungles of Thailand has been awarded a national prize for his invention of a $2 paper microscope that can be taken on field expeditions.

If a scientist wants to study something at the microscopic level, they need a microscope, which if they are deep in the Amazon Rainforest presents a serious problem.

Stanford University bioengineer Manu Prakash saw in his team’s $50,000 microscope a serious contradiction. As well as being bulky and ridiculously challenging to transport to remote locations, it needed training from skilled technicians to know how to use it. It also had to stay well out of the weather and other environmental impacts.

So he invented a portable one. Costing $1.75, the Foldscope has a 140x zoom, which is a small enough field to see a malaria parasite inside a cell…

“I want to bring science into everyone’s hands, make it more personal,” Prakash told CNN. “We have decoupled everyday life from the process of science.”

The ultimate in schoolhouse science, Prakash’s invention has sold 1.6 million units, mostly to schools in America, but serious scientists are also using it—like Dr. Kirti Nitnaware in India who works on the isolation and characterization of bioactive metabolites in cyanobacteria.

She used the Foldscope last year to isolate a new species of cyanobacteria. For this and other reasons, Prakash received the 2022 Golden Goose Award from the American Association for the Advancement of Science (AAAS), parent company of the scientific journal, Science.

“The Golden Goose Award reminds us that potential discoveries could be hidden in every corner and illustrates the benefits of investing in basic research to propel innovation,” said Sudip S. Parikh, chief executive officer at AAAS.” -via Good News Network, 9/20/22

“Costing $1.75, the Foldscope has a 140x zoom, which is a small enough field to see a malaria parasite inside a cell.” The implications of this sentence alone are huge.

This news is a bit older, but it’s still super relevant for the ways that it will massively expand science and research capabilities around the world - especially for citizen science and in developing countries.

And this guy has also gone on to design another revolutionary kind of microscope that could change how we detect disease:

“Rapid diagnostic tests can quickly check whether someone has malaria, but they don’t count the number of parasites. That figure is important: It reveals the severity of an infection and informs treatment choices. To count parasites, you need trained technicians and good microscopes. “There’s incredible talent, but it’s limited by their tools,” Prakash says. “I would meet health-care workers who would save their salary for a year to buy a fancier microscope.”

So Prakash and his colleague Hongquan Li built a fancier microscope—a high-speed, malaria-detecting device that they’ve called Octopi. It can automatically scan entire blood-smeared slides for malaria parasites, using a neural network trained on more than 20,000 existing images. Octopi works off a phone charger. It analyzes slides at speeds that are 120 times faster than traditional microscopy. Weighing fewer than seven pounds, it’s portable. And at a do-it-yourself cost of $250 to $500, it’s cheaper than many basic microscopes or other automated slide-analyzing devices.

Prakash has spent his career building extremely cheap medical devices that can be used in some of the poorest parts of the world. Besides the Foldscope, he developed a $10 skin patch that can detect parasitic worms. And he developed a 20-cent, hand-powered centrifuge that can spin medical samples at up to 125,000 revolutions per minute, achieving what costly, bulky, and expensive machines can do using little more than paper, string, and tape.”

Volcanoes on Jupiter's moon Io keep erupting. To investigate, NASA's robotic Juno spacecraft has begun a series of visits to this very strange moon. Io is about the size of Earth's moon, but because of gravitational flexing by Jupiter and other moons, Io's interior gets heated and its surface has become covered with volcanoes. The featured image is from last week's flyby, passing within 12,000 kilometers above the dangerously active world. The surface of Io is covered with sulfur and frozen sulfur dioxide, making it appear yellow, orange and brown. As hoped, Juno flew by just as a volcano was erupting -- with its faint plume visible near the top of the featured image.

"Two and a half years ago, when I was asked to help write the most authoritative report on climate change in the United States, I hesitated...

In the end, I said yes, but reluctantly. Frankly, I was sick of admonishing people about how bad things could get. Scientists have raised the alarm over and over again, and still the temperature rises. Extreme events like heat waves, floods and droughts are becoming more severe and frequent, exactly as we predicted they would. We were proved right. It didn’t seem to matter.

Our report, which was released on Tuesday, contains more dire warnings. There are plenty of new reasons for despair. Thanks to recent scientific advances, we can now link climate change to specific extreme weather disasters, and we have a better understanding of how the feedback loops in the climate system can make warming even worse. We can also now more confidently forecast catastrophic outcomes if global emissions continue on their current trajectory.

But to me, the most surprising new finding in the Fifth National Climate Assessment is this: There has been genuine progress, too.

I’m used to mind-boggling numbers, and there are many of them in this report. Human beings have put about 1.6 trillion tons of carbon in the atmosphere since the Industrial Revolution — more than the weight of every living thing on Earth combined. But as we wrote the report, I learned other, even more mind-boggling numbers. In the last decade, the cost of wind energy has declined by 70 percent and solar has declined 90 percent. Renewables now make up 80 percent of new electricity generation capacity. Our country’s greenhouse gas emissions are falling, even as our G.D.P. and population grow.

In the report, we were tasked with projecting future climate change. We showed what the United States would look like if the world warms by 2 degrees Celsius. It wasn’t a pretty picture: more heat waves, more uncomfortably hot nights, more downpours, more droughts. If greenhouse emissions continue to rise, we could reach that point in the next couple of decades. If they fall a little, maybe we can stave it off until the middle of the century. But our findings also offered a glimmer of hope: If emissions fall dramatically, as the report suggested they could, we may never reach 2 degrees Celsius at all.

For the first time in my career, I felt something strange: optimism.

And that simple realization was enough to convince me that releasing yet another climate report was worthwhile.

Something has changed in the United States, and not just the climate. State, local and tribal governments all around the country have begun to take action. Some politicians now actually campaign on climate change, instead of ignoring or lying about it. Congress passed federal climate legislation — something I’d long regarded as impossible — in 2022 as we turned in the first draft.

[Note: She's talking about the Inflation Reduction Act and the Infrastructure Act, which despite the names were the two biggest climate packages passed in US history. And their passage in mid 2022 was a big turning point: that's when, for the first time in decades, a lot of scientists started looking at the numbers - esp the ones that would come from the IRA's funding - and said "Wait, holy shit, we have an actual chance."]

And while the report stresses the urgency of limiting warming to prevent terrible risks, it has a new message, too: We can do this. We now know how to make the dramatic emissions cuts we’d need to limit warming, and it’s very possible to do this in a way that’s sustainable, healthy and fair.

The conversation has moved on, and the role of scientists has changed. We’re not just warning of danger anymore. We’re showing the way to safety.

I was wrong about those previous reports: They did matter, after all. While climate scientists were warning the world of disaster, a small army of scientists, engineers, policymakers and others were getting to work. These first responders have helped move us toward our climate goals. Our warnings did their job.

To limit global warming, we need many more people to get on board... We need to reach those who haven’t yet been moved by our warnings. I’m not talking about the fossil fuel industry here; nor do I particularly care about winning over the small but noisy group of committed climate deniers. But I believe we can reach the many people whose eyes glaze over when they hear yet another dire warning or see another report like the one we just published.

The reason is that now, we have a better story to tell. The evidence is clear: Responding to climate change will not only create a better world for our children and grandchildren, but it will also make the world better for us right now.

Eliminating the sources of greenhouse gas emissions will make our air and water cleaner, our economy stronger and our quality of life better. It could save hundreds of thousands or even millions of lives across the country through air quality benefits alone. Using land more wisely can both limit climate change and protect biodiversity. Climate change most strongly affects communities that get a raw deal in our society: people with low incomes, people of color, children and the elderly. And climate action can be an opportunity to redress legacies of racism, neglect and injustice.

I could still tell you scary stories about a future ravaged by climate change, and they’d be true, at least on the trajectory we’re currently on. But it’s also true that we have a once-in-human-history chance not only to prevent the worst effects but also to make the world better right now. It would be a shame to squander this opportunity. So I don’t just want to talk about the problems anymore. I want to talk about the solutions. Consider this your last warning from me."

-via New York Times. Opinion essay by leading climate scientist Kate Marvel. November 18, 2023.

Culture is so obsessed with the idea of lone geniuses that it doesn’t really appreciate that most of the progress of science (and likely every other discipline) occurs collaboratively, in babysteps, and usually through a lot very tedious, utterly unsexy, work.

This is what’s so faulty with our short sighted coverage of scientific discoveries. You hear politicians question why we spend money on science studying insect wings and then decades later that research gets used by NASA for the most efficient way to fold/unfold solar panels on spacecraft. All of science is connected and useful because it enhances our understanding of the universe

When lasers were discovered they were called “a solution without a problem”, noone had any idea what to use them for. Since then they’re revolutionised communications and SO many parts of technology. CDs, DVDs, printing, fast internet, laser etching for making computer chips, laser eye surgery, spectroscopy, LIDAR measurements of weather patterns, barcode scanners, cooling atomic clocks, nuclear fusion, microscopy, LED technology and materials research. I’m probably not even scratching the surface here. Fund theory and fundamental science research.

It’s actually kind of heartening, lasers; because before they were invented, their only real antecedents in science fiction were things like rayguns and heatrays and what not. But it actually turns out that their usefulness as a weapon is extremely limited, whereas their usefulness for just about everything else is incredible. It’s one of the occasions where we flipped the “Dual Use” coin and it landed very solidly on the good side.

Theoretical research in the sciences is the unfallen version of Fuck Around and Find Out. 😀

BlackGEM telescopes begin hunt for gravitational-wave sources at ESO's La Silla Observatory

The BlackGEM array, consisting of three new telescopes located at ESO’s La Silla Observatory, has begun operations. The telescopes will scan the southern sky to hunt down the cosmic events that produce gravitational waves, such as the mergers of neutron stars and black holes.

Some cataclysmic events in the Universe, such as the collision of black holes or neutron stars, create gravitational waves, ripples in the structure of time and space. Observatories like the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo Interferometer are designed to detect these ripples. But they cannot pinpoint their origin very accurately nor see the fleeting light that results from the collisions between neutron stars and black holes. BlackGEM is dedicated to quickly scanning large areas of the sky to precisely hunt down gravitational-wave sources using visible light.
