For Black and Brown Kidney Patients, There Are Higher Hurdles to Care
Posted in Cool

The international actuarial and consulting firm Milliman estimates that the average billable cost for a kidney transplant in 2020 is $442,500. Both Black and Hispanic patients were less likely to receive this care compared to White patients. Indeed, according to an analysis of data from 1990 to 2009, Black patients waited an average of 2.5 months longer than White patients for a kidney transplant. Despite such changes in organ donation, Black patients on dialysis are still far less likely than White patients to receive a living donor kidney. Black patients, then, tend to reach out to fellow Black family and friends.

What Is Chronic Kidney Disease, and How Might It Affect You?
Posted in Cool

This is called Chronic Kidney Disease and it’s a growing global problem. Unless a donor kidney can be found for a transplant - patients with kidney failure require dialysis. Dialysis does not cure kidney disease and in the case of end stage kidney failure—a patient must remain on dialysis until a new kidney can be found. And yet, studies show that despite having higher rates of kidney disease, racial and ethnic minorities often struggle to afford dialysis. But for those with chronic kidney disease, there is really only one option: stay in the system, stay on dialysis, wait for a kidney—or die.

Did We Receive a Message from a Planet Orbiting the Nearest Star?
Posted in Cool

This infrared star hosts an Earth-size planet, Proxima b, in its habitable zone, where liquid water could allow the chemistry of life on the planet’s surface. But even without examining the event details, one might wonder whether it is plausible for a radio signal to originate from our nearest star system. Following this argument, the quantitative paper with Amir shows that the chance of a radio signal appearing now from our nearest star is miniscule. There is one caveat to this conclusion, namely if intelligent life on Earth and its nearest star are correlated. Interestingly, Proxima Centauri became our nearest star around the same time when Homo sapiens appeared on Earth.

The Misunderstood Legacy of Martin Luther King Jr.

\" \" A mule-drawn wagon carrying the casket of Dr. Martin Luther King Jr., is followed by dignitaries and thousands of people as it moves en route to Morehouse College, Atlanta for his memorial service on April 9, 1968. \"The same criticisms made against Colin Kaepernick and the Black Lives Matter movement today were trotted out against Martin Luther King and Rosa Parks 60 years ago. But Clayborne Carson, history professor at Stanford University and founding director of The Martin Luther King, Jr. Research and Education Institute, points out that King didn't retire after the passage of the Voting Rights Act. Of course, Americans have every reason to venerate Martin Luther King and to celebrate his accomplishments.

Twitter Bots Are a Major Source of Climate Disinformation
Posted in Cool

Twitter accounts run by machines are a major source of climate change disinformation that might drain support from policies to address rising temperatures. “Twitter bots have been this growing force of evil over a half a decade now,” said John Cook, a professor at George Mason University’s Center for Climate Change Communication who was not involved with the study. “Twitter bots have been a part of that.”Marlow’s team measured the influence of bots on Twitter’s climate conversation by analyzing 6.8 million tweets sent by 1.6 million users between May and June 2017. But those bots accounted for 25% of the total tweets about climate change on most days. The bots were also more prevalent in discussions on climate research and news.

New Technology Turns a Sunny Day into Safe Water

\" \" More than 2 billion people worldwide live without access to safe, clean water. As the problem is exacerbated by climate change, scientists have come up with a new solution using sunlight, a plentiful resource. That's enough drinking water for four people for one day. Ramping up production for large-scale purification is still in development, but this method is encouraging as an additional means of securing safe water for a growing population. It's time to see the future of clean water in a whole new light.

10 Widely Believed U.S. Government Conspiracy Theories

Muslim terrorist group al-Qaida claimed responsibility for the attacks. But almost immediately, conspiracy theories started flying around. Some theorists believed that the U.S. government had advance warning of the attacks, but let them happen anyway. Others claimed that the government actually engineered the attacks, and that al-Qaida wasn't even involved. There was also a lack of booming sounds and flashes of light characteristic of explosions [source: Thomas].

Earth Has Lost 28 Trillion Tons of Ice since the Mid-1990s
Posted in Cool

Altogether, the planet lost a whopping 28 trillion tons of ice between 1994 and 2017. It accounts for both the Greenland and Antarctic ice sheets, Arctic and Antarctic sea ice and mountain glaciers all over the world. Since the 1990s, Antarctica has lost more than 2.6 trillion tons and Greenland has lost nearly 4 trillion. These ice shelves help to stabilize the ice sheet’s marine-terminating glaciers and hold back the flow of ice behind them. In addition to the ice sheet’s losses, Antarctica’s ice shelves have lost more than 8.6 trillion tons of mass since the 1990s.

Where do Meteor Showers come from?

The Most Worrying Mutations in Five Emerging Coronavirus Variants
Posted in Cool

When they occur, most mutations either kill the virus or cause no change in its structure or behavior. Although improved surveillance and sequencing efforts might partly explain why these variants are appearing now, some repetition in their patterns suggest the mutations are not random. “What we’re seeing is similar mutations arising in multiple places,” says Adam Lauring, a virologist at the University of Michigan. It is unclear, however, whether the variant’s enhanced contagiousness comes from N501Y alone or also involves some combination of other spike protein mutations. Although they share mutations with other newly discovered versions, they appear to have arisen independently of those variants.

What's the Difference Between Global Warming and Climate Change?
Posted in Cool

UAF/Martin TrufferOn Aug. 18, 2019, Iceland held a funeral for the first glacier lost to climate change. With public concern on the rise, two relevant terms have entered the lexicon: \"Climate change\" and \"global warming.\" That hypothetical scenario would count as an example of regional climate change, no matter what happened elsewhere in the world. On the other hand, global warming is — well, global. The main takeaway here is that global warming is a form of climate change — but climate change doesn't always manifest itself as global warming.

Hemp Batteries are Eight Times More Powerful than Lithium, Scientists Discover
Posted in Cool

January 5, 2021 at 6:46 pmWaste fibers from hemp crops out-perform graphene for a thousandth of the cost, according to new researchIs there anything hemp can’t do? A year after hemp became legal to grow in the United States, we’ve seen its power to make better clothing, better buildings and better medicine. Now, there’s something else hemp appears to be better at – making batteries. Most auto batteries today are made from lithium-ion, an expensive, quickly disappearing material. Graphene is a synthetic carbon material lighter than foil yet bulletproof, but it is prohibitively expensive to make.

Are Hemp Batteries Better Than Lithium-Ion?
Posted in Cool

A reader asked me about this story – “Hemp Batteries are Eight Times More Powerful than Lithium, Scientists Discover.” I didn’t believe it for a second. Are they referring to energy density, power density, by mass or volume, and in any case what are the other critical features, like charge-discharge cycles? Here is the paper on which it is reporting – Interconnected Carbon Nanosheets Derived from Hemp for Ultrafast Supercapacitors with High Energy. The original study heated the bast from from hemp waste (hemp is an industrial form of marijuana) to create “graphitic carbon nanosheets”. An energy storage device with 22 times less energy density than current Li-Ion batteries is not viable for cars, period.

How Did Benjamin Gompertz Predict Our Deaths?
Posted in Cool

It didn't really seem to bother Benjamin Gompertz much. And what the Gompertz law of mortality tells us is just as chilling today as it was then. Though the family was wealthy enough, they were also Jewish, which excluded Benjamin from studying at a university at that time. And in case you were wondering, Benjamin Gompertz died at the ripe old age of 86. Now That's Interesting The Gompertz Mortality Law works for pretty much all mammals after they reach sexual maturity.
