Here’s something which is out of the ordinary, even for me. The original idea goes back a couple hundred years, but the technology now looks like it has caught up to what the dreamers have imagined.

Please watch the video with an open mind. Consider the possibilities for paraplegics or soon to die cancer patients. The idea may seem weird or even repulsive to you today,, but it could offer hope for a few brave souls willing to risk everything.

Fungus Growing at Chernobyl Could Protect Astronauts From Cosmic Rays

Space Shields

One of the biggest challenges facing crewed missions to Mars is figuring out how to protect crewmembers from the onslaught of deadly cosmic rays.

Now, scientists at a number of universities say there’s growing evidence that an unusual solution could be effective: building shields out of a radiation-absorbing fungus that grows near the Chernobyl Nuclear Power Plant. New Scientist reports that the fungus was able to block some cosmic rays after a small test on the International Space Station, giving hope for safe space travel in the future.

New Paper Demonstrates Strong Efficacy of Hydroxychloroquine. Mortality rate cut in half!

Posted by Jeff Id – Re-Blogged From WUWT

Treatment with Hydroxychloroquine, Azithromycin, and Combination in Patients Hospitalized with COVID-19

A new study of over 2000 hospitalized patients reveals that Hydroxychloroquine works very well in treatment of COVID.  The reason I’m so excited about this one is because unlike the poor studies that I’ve written about already, this study controlled the dosages, use the correct levels of HCQ and Azythromycin per other studies, and matched patients to each other by their own health situations.  This matching of health condition is the proper method to control the confounding factors in a situation where testing cannot be double-blind.  The health of the patient is what the frustratingly fake studies didn’t correct for, but certain political pressures made them popular.

This is absolutely the most conclusive research produced to date by anyone, due mostly to the quality of the approach.  No one has published this quality level of work on HCQ on humans prior to this.

Solar Panel-Like Device Generates Power From Darkness

Dark Energy

A strange new device — think of it as a Bizarro World version of solar panels — is capable of generating electricity from darkness.

The gadget, dubbed a “shadow-effect energy generator,” is a solar cell-like material that generates an electrical current when part of it is in the light and the other part isn’t, Science News reports. While the electric current from the proof-of-concept generators is weak for now, it hints at a future in which clean energy generation becomes far more ubiquitous and commonplace.

Closed Spaces

When only part of the generator is illuminated, electrons flow across a gold coating from light to dark areas. Capturing that flow, according to research published in the journal Energy & Environmental Science, generates power twice as effectively as conventional solar cells blanketed by shade.

“We can harvest energy anywhere on Earth, not just open spaces,” National University of Singapore materials scientist Swee Ching Tan told Science News.

First Steps

While these generators can’t solve the energy crisis yet, Science News suggested that it could be used to power wearables like smart watches, which can’t depend on steady or full sunlight.

“A lot of people think that shadows are useless,” Tan told Science News. “Anything can be useful, even shadows.”

Scientists Say Nanobots Could Kill Individual Cancer Cells

By Dan Robitzski – Re-Blogged From Futurism
They could also be used to track, target, and deliver anticancer drugs to tumor cells.

A team of scientists from Saudi Arabia is planning to implant individual cells with iron nanobots that can track their location in the body — and perhaps even kill off tumors.

The tiny nanobots, little more than microscopic coils of metal wires, would show up during an MRI scan, allowing doctors to watch their movement through the body. They could also be used to track, target, and deliver anticancer drugs to tumor cells, according to the King Abdullah University of Science and Technology researchers behind the project.

“Cell labeling and tracking has become an invaluable tool for scientific and clinical applications,” Aldo Martinez-Banderas, a grad student who worked on the project, said in a press release. “One of the key aspects of cell tracking studies is the sensitivity to detect a small number of cells after implantation, so the strong magnetization and biocompatibility of our nanowires are advantageous characteristics for MRI tracking.”

So far, the nanobots haven’t been used to actually kill off cancer cells, though the team has ideas on how they might. Thus far, the nanobots were used to successfully identify breast cancer cells through MRI readings, according to research published in the Journal of Nanobiotechnology.

“These core-shell nanowires have various additional features, including the ability to control them magnetically to guide them to a particular location, to carry drugs, or be to heated with a laser,” lead researcher Jürgen Kosel said in the release. “Combining all of that with the capability of tracking creates a theranostic platform that can open the door for very promising new approaches in nanomedicine.”

MIT Invents $6 COVID-19 Test Using CRISPR

By Dan Robitzski – Re-Blogged From Futurism

[The test is only to see if you now have COVID. It does not test for antibodies. –Bob]

They hope it can help solve the testing crisis in the US.

A new coronavirus test uses gene-hacking tech to determine whether someone is sick with COVID-19 — and it only costs $6 to make.

Because there are still too few tests to go around, a pair of MIT researchers set out to build something to be as low-cost and self-contained as possible, The New York Times reports. The result is a two-step test that uses CRISPR to scan a patient’s saliva or nasal swab for signs of the coronavirus’ genetic code.

“We’re excited that this could be a solution that people won’t have to rely on a sophisticated and expensive laboratory to run,” said Feng Zhang, a researcher at MIT and the Broad Institute who developed the test, told the NYT.

The test’s website makes it very clear that it’s not approved for clinical use yet. As the NYT reports, the test performed well in early experiments, but their scope was limited — the researchers only administered it to 12 sick patients and a control group of five healthy people.

Here’s how it works: The patient’s nasal swab or saliva is deposited into a tube with chemicals that rip open viruses. The concoction is then dropped into a second tube full of CRISPR molecules that search for the coronavirus. In order to work, that second tube needs to stay at 140 degrees Fahrenheit for a full hour.

The test gives results similar to those of an at-home pregnancy test, the NYT reports. A strip of paper is dipped in, and if two lines appear, the test was positive.

The researchers behind the test told the NYT that they’re talking to manufacturers to mass-produce a one-vial version, which they hope can help solve the testing crisis in the U.S.

Scientists Create Jet Engine Powered by Only Electricity

Clean Air

A prototype jet engine can propel itself without using any fossil fuels, potentially paving the way for carbon-neutral air travel.

The device compresses air and ionizes it with microwaves, generating plasma that thrusts it forward, according to research published Tuesday in the journal AIP Advances. That means planes may someday fly using just electricity and the air around them as fuel.

Scaling Up

There’s a long way to go between a proof-of-concept prototype and installing an engine in a real plane. But the prototype was able to launch a one-kilogram steel ball 24 millimeters into the air. That’s the same thrust, proportional to scale, as a conventional jet engine.

“Our results demonstrated that such a jet engine based on microwave air plasma can be a potentially viable alternative to the conventional fossil fuel jet engine,” lead researcher and Wuhan University engineer Jau Tang said in a press release.

Air Jet

Air travel represents a small but not insignificant portion factor of climate change. The New York Times reported in September that commercial air is responsible for 2.5 percent of all greenhouse gas emissions — though that excludes military jets.

“The motivation of our work is to help solve the global warming problems owing to humans’ use of fossil fuel combustion engines to power machinery, such as cars and airplanes,” Tang said in the release. “There is no need for fossil fuel with our design, and therefore, there is no carbon emission to cause greenhouse effects and global warming.”

Scientists Say New Nanomaterial Could “Replace Human Tissue”

Altered Carbon

European researchers say they’ve invented a rubbery nanomaterial that seamlessly integrates with the human body — which could pave the way for everything from new reconstructive surgeries to extreme body modification.

“We were really surprised that the material turned out to be very soft, flexible and extremely elastic,” said Anand Rajasekharan, one of the researchers behind the new material, in a press release that claimed the material could “replace human tissue.”

Human Tissue

The nontoxic material, described in depth by scientists at Chalmers University in Sweden in a new paper in the journal ACS Nano, is made of the same stuff as plexiglass.

Salamander DNA Could Regenerate Human Body Parts

“It’s hard to find a body part they can’t regenerate: the limbs, the tail, the spinal cord, the eye, and in some species, the lens, even half of their brain has been shown to regenerate.”

For the first time, scientists have completely sequenced the genome of the axolotl, a bizarre salamander that’s capable of regenerating many of its body parts after an injury.

By unlocking the entirety of the axolotl’s genetic code, according to a press release, doctors from the University of Kentucky hope that they may be able to use it in human medicine. By developing new genetic treatments, they hope that someday humans may be able to regenerate missing limbs or reverse other damage, like salamanders do.

These insulin-secreting cells cured mice from severe diabetes “within two weeks.”

A team of researchers at the Washington University School of Medicine in St. Louis successfully converted human stem cells into cells capable of producing insulin. These insulin-producing cells were then able to control blood sugar levels in a demonstration involving diabetic mice.

“These mice had very severe diabetes with blood sugar readings of more than 500 milligrams per deciliter of blood — levels that could be fatal for a person — and when we gave the mice the insulin-secreting cells, within two weeks their blood glucose levels had returned to normal and stayed that way for many months,” lead researcher Jeffrey Millman, assistant professor at Washington University, said in a statement.

Human Trial Suggests CRISPR Could Be a Viable Cancer Treatment

By Kristin Houser – Re-Blogged From Futurism

This could be great news for experimental cancer treatments.

Scientists from the University of Pennsylvania just published the results of the first U.S. trial of CRISPR-edited cells in cancer patients — and they’re very encouraging.

In April 2019, UPenn confirmed that a team of its researchers had officially begun testing CRISPR-edited cells in humans.

For that trial, the scientists had removed immune cells from three patients with advanced, treatment-resistant cancers. They then used CRISPR-Cas9 to edit the cells in order to improve their ability to fight tumors before returning them to the patients’ bodies.

Researchers Transplant Lab-Grown Heart Muscle Cells Into Patient

By Kristin Houser – Re-Blogged From Futurism

This first-of-its-kind procedure could replace heart transplants.

On Monday, researchers from Japan’s Osaka University announced the successful completion of a first-of-its-kind heart transplant.

Rather than replacing their patient’s entire heart with a new organ, these researchers placed degradable sheets containing heart muscle cells onto the heart’s damaged areas — and if the procedure has the desired effect, it could eventually eliminate the need for some entire heart transplants.

To create the heart muscle cells, the team started with induced pluripotent stem (iPS) cells. These are stem cells that researchers create by taking an adult’s cells — often from their skin or blood — and reprogramming them back into their embryonic-like pluripotent state.

Scientists Discover Immune Cell That Kills Most Cancers

By Kristin Houser – Re-Blogged From Futurism

“Previously nobody believed this could be possible.”

A newly discovered immune cell could lead to the creation of a universal cancer treatment — a “Holy Grail” treatment that would work for all cancers, in all people.

The treatment leverages T-cells, a type of white blood cell that helps our bodies’ immune systems by scanning for and killing abnormal cells. For background, scientists have recently started harnessing that ability in the fight against cancer through a therapy called CAR-T, which involves removing T-cells from a patient’s blood and genetically engineering them to seek out and destroy cancer cells.

Lab-Grown Minibrains Show Activity Similar to Babies’ Brains

By Shelly Fan – Re-Blogged From Singularity Hub

Neurons are a collective bunch. Although each neuron receives, processes, and passes on information individually, the electrical spikes only make sense when melded together in waves of oscillating activity. Like an orchestra, the notes played from each neuron matter. But only when they synchronize in specific ways do single notes transform into the music of thought, memories, and actions.

By studying animals, scientists have long known that even extremely young brains—say, those still in the mother’s womb—gradually generate neural oscillations as they mature. Genetic mutations that disrupt this synchronicity causes the melody to falter, leading to neurodevelopmental problems including autism, epilepsy, or schizophrenia. Yet those ideas remain educated guesses, mostly because it’s impossible to monitor a developing human fetus’s brain.

NASA Testing Method to Grow Bigger Plants in Space

By Danielle Sempsrott of NASA – Re-Blogged From WUWT

In an effort to increase the ability to provide astronauts nutrients on long-duration missions as the agency plans to sustainably return to the Moon and move forward to Mars, the Veg-PONDS-02 experiment is currently underway aboard the International Space Station.

The present method of growing plants in space uses seed bags, referred to as pillows, that astronauts push water into with a syringe. Using this method makes it difficult to grow certain types of “pick and eat” crops beyond lettuce varieties. Crops like tomatoes use a large amount of water, and pillows don’t have enough holding capacity to support them.

Why Facts Don’t Change Our Minds

By Elizabeth Kolbert – Re-Blogged From The New Yorker

In 1975, researchers at Stanford invited a group of undergraduates to take part in a study about suicide. They were presented with pairs of suicide notes. In each pair, one note had been composed by a random individual, the other by a person who had subsequently taken his own life. The students were then asked to distinguish between the genuine notes and the fake ones.

Some students discovered that they had a genius for the task. Out of twenty-five pairs of notes, they correctly identified the real one twenty-four times. Others discovered that they were hopeless. They identified the real note in only ten instances.

As is often the case with psychological studies, the whole setup was a put-on. Though half the notes were indeed genuine—they’d been obtained from the Los Angeles County coroner’s office—the scores were fictitious. The students who’d been told they were almost always right were, on average, no more discerning than those who had been told they were mostly wrong.

Does Government R&D Policy Mainly Benefit Scientists and Engineers?

By Larry Kummar – Re-Blogged From WUWT

Does this apply to Climate Science?

Paper By Austan Goolsbee

NBER Working Paper No. 6532, Issued in April 1998

Conventional wisdom holds that the social rate of return to R&D significantly exceeds the private rate of return and, therefore, R&D should be subsidized. In the U.S., the government has directly funded a large fraction of total R&D spending.

This paper shows that there is a serious problem with such government efforts to increase inventive activity. The majority of R&D spending is actually just salary payments for R&D workers. Their labor supply, however, is quite inelastic so when the government funds R&D, a significant fraction of the increased spending goes directly into higher wages. Using CPS data on wages of scientific personnel, this paper shows that government R&D spending raises wages significantly, particularly for scientists related to defense such as physicists and aeronautical engineers. Because of the higher wages, conventional estimates of the effectiveness of R&D policy may be 30 to 50% too high.

The results also imply that by altering the wages of scientists and engineers even for firms not receiving federal support, government funding directly crowds out private inventive activity.

“The meeting this year is about ‘Science Transcending Boundaries’–the idea for the session is to highlight research that is transcending scientific and knowledge boundaries, with the ultimate goal to transcend geographic boundaries and reach smallholder farmers in Africa,” said Lisa Ainsworth, a scientist with the U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) and an adjunct professor of plant biology at the University of Illinois. Recently, Ainsworth was awarded the 2019 National Academy of Sciences Prize in Food and Agriculture Sciences.

Parkinson’s Brain Damage Reversed in Study

By Health Day – Re-Blogged From Newsmax Health

It may be possible to restore brain cells damaged by Parkinson’s disease and reverse a patient’s condition, something no current treatment can do, according to British researchers who conducted potentially groundbreaking clinical trials.

They cautioned the trial was small — just 41 patients — and the research is still in its early days. But the results of the approach, which delivers special “growth factor” proteins to restore failing brain cells, are very promising.

“The spatial and relative magnitude of the improvement in the brain scans is beyond anything seen previously in trials of surgically delivered growth-factor treatments for Parkinson’s,” principal investigator Dr. Alan Whone said in a news release from Parkinson’s UK, which helped fund the study.

Researchers Chart Path to Cheaper Flexible Solar Cells

By Georgia Institute of Technology – RE_Blogged From Eureka Alert

There’s a lot to like about perovskite-based solar cells. They are simple and cheap to produce, offer flexibility that could unlock a wide new range of installation methods and places, and in recent years have reached energy efficiencies approaching those of traditional silicon-based cells.

But figuring out how to produce perovskite-based energy devices that last longer than a couple of months has been a challenge.

Now researchers from Georgia Institute of Technology, University of California San Diego and Massachusetts Institute of Technology have reported new findings about perovskite solar cells that could lead the way to devices that perform better.

Alternative to Spine Surgery: A Single Shot of Human Cells

By Mary Martin – Re-Blogged From Newsmax Health

What if a single-dose injection could cure degenerative disk disease, without going under the knife and through the recovery process of spine surgery? Though it sounds too good to be true, pioneering medical company SpinalCyte says not only is it possible, but it’s already being done.

In a recently concluded clinical trial, the company reported that a single injection of fibroblast cells — modified human cells similar to stem cells — resulted in significant improvements in disk height and pain reduction 12 months after the initial shot.

Stem Cell Transplant Helps Some With MS

By Health Day – Re-Blogged From Newsmax Health

A stem cell transplant may help some people with multiple sclerosis when standard drugs fail, a new clinical trial finds.

The study focused on 110 patients with aggressive cases of MS: Their symptoms had flared up at least twice in the past year despite taking standard medication, and they’d already tried an average of three of those drugs.

Researchers randomly assigned the patients to either keep trying other medications or have a stem cell transplant — using cells taken from their own blood.

Over an average of three years, MS progressed in 34 of 55 patients on medication — meaning their disabilities worsened. That compared with only three of 55 patients given a stem cell transplant.

Tests May Help Diagnose Alzheimer’s Earlier

By Health Day – Tr-Blogged From Newsmax Health

Leaky blood vessels in the brain may be an early sign of Alzheimer’s disease, researchers say.

They followed 161 older adults for five years and found that those with the most severe memory declines had the greatest leakage in their brain’s blood vessels, regardless of whether the Alzheimer’s-related proteins amyloid and tau were present.

Chinese Researcher Claims First Gene-Edited Babies

By Christina Larsen – Re-Blogged From APNews

HONG KONG (AP) — A Chinese researcher claims that he helped make the world’s first genetically edited babies — twin girls born this month whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.

If true, it would be a profound leap of science and ethics.

A U.S. scientist said he took part in the work in China, but this kind of gene editing is banned in the United States because the DNA changes can pass to future generations and it risks harming other genes.

Just 6 Months of Walking May Boost Aging Brains

By Health Day – Re-Blogged From Newsmax Health

Walking and other types of moderate exercise might help turn back the clock for older adults who are losing their mental sharpness, a new clinical trial finds.

The study focused on older adults who had milder problems with memory and thinking skills. The researchers found that six months of moderate exercise – walking or pedaling a stationary bike – turned some of those issues around.

Specifically, exercisers saw improvements in their executive function – the brain’s ability to pay attention, regulate behavior, get organized and achieve goals. And those who also made some healthy diet changes, including eating more fruits and vegetables, showed somewhat bigger gains.

The effect was equivalent to shaving about nine years from their brain age, said lead researcher James Blumenthal, a professor at Duke University School of Medicine, in Durham, N.C.
