Science.
It’s the reason for the modern world
Why medicine is a thing
How technology comes to exist
A great collection of facts that have given humanity access to reliable knowledge
Reliable because it is derived rationally, based on evidence and experimentation.

Take the evidence of facts collected by thousands of scientists using the scientific method on the subject of global warming.
Increases in atmospheric carbon
Global temperature rise
Warming oceans
Melting ice sheets
Retreating glaciers
Decreased snow cover
Rising sea levels
Increases in extreme weather events
Ocean acidification

Now contrast that with a politician who says
“It’ll just start getting cooler, you just watch,
I don’t think science knows, actually,”
And while not thinking science knows is nothing new amongst politicians, cigarette manufacturers, the fossil fuel industry, religion, racists, lawyers fighting dna evidence, who ever’s job it is to convince people to wear magnets, go on a pre-packaged diet or avoid vaccinating their kids…
None of these are reliable sources of information.

Science works because it comes from the most reliable source of information humans have ever discovered… a combination of reality, rational unbiased methodology, and of course
This Week in Science,
Coming Up Next…

Let’s start with some quick science news stories…

Wobbly Ring
Remember that picture of a black hole that we were gifted with last year? Well, a review of data from several previous observations of the black hole at the center of galaxy M87, and a little mathematical computer aided zhoozhing has now resulted in a movie that shows changes in the matter in the accretion disc around the event horizon. It looks like it has a wobbly hoola-hoop.

Covid Cats
They get it.

Oldest sperm
It’s really old.

Pi Planet
With an orbital period of just 3.14 days, K2-315b is the Earth-sized exoplanet that Pi fans will love.

Close Call
School bus-size asteroid to safely zoom past Earth

Early Arsenic Life
Adding to evidence suggesting that earth’s early micro-organisms likely photosynethsized in the absence of oxygen, researchers have found oxygen-free modern microbial mats in the high-altitude Atacama desert that appear to use arsenic instead.

Humans have had a good run on planet earth.
Yes there are a multitude of life forms that have persisted much longer than the human blip upon the scene of life…
But there have likely been few life forms that have as dramatically effected the lives of so many others, as humans have done.
And while humans are having their moment now,
at the height of science,
at the height of technology,
at the height of agriculture,
at the height economy,
at the height of communication,
collaboration and inter-connectivity…
And also at the very height of hubris…
In thinking that the world belongs to them and will so remain,
undeterred by their activities
Humans are but one form of life on this earth…
the after effect of a recent adaptation among apes.
An adaptation that has led to a radical break with nature.
And the actions of these unnatural apes upon the planet
is leading to consequences for all of its inhabitants.
It is only a matter of time before these consequences become too great to bear.
A time when…
All of humans history will be but evidenced in ocean trash and atmospheric carbon
A time when…
All of humanities accomplishments will lay as artifacts under the sea
A time when…
All of science will be as all lost species, extinct and forgotten
A time when…
All of art and culture is discarded to the decay of time
A time when…
All of the roads laid will lead from cities devoured by nature
To bridges that do not span the far shores
A time when everything they held as human,
and everything they knew about the universe
Is simply plowed under
A billion years gone from the surface of the earth
When all of human history is but a dream
The only thing worth remembering about them will be
This Week in Science

Let’s start with some quick science news stories…

LIFE ON VENUS
But, we don’t really know.

Life On Mars?
Even if there was life on Mars, the surface conditions might have degraded it to a point beyond recognition.

Latest magnetic field hypothesis: animal navigation through bacteria
Bacteria sensitive to magnetic fields could be responsible for turtle, penguin, and other animal navigation, and could be used to aid human navigation. Question is, can I infect myself and get an amazing sense of direction??

Cave fish Brains
Brain mapping of Mexican tetra species confirms that unique evolutionary adaptations underlie behavioral differences between surface-dwelling and blind cave fish species.

ORCAs defend waters from boats off the coast of Spain
Or, maybe it’s something else?

Whale Pollution
Whales in Ecuador and Mozambique have persistent organic pollutants in their blubber. However, the contaminants are at very low levels suggesting that there is little impact of whale health at this point.

Now for the weekly COVID-19 Update!

COVID Update
The US is averaging 35,752 new cases and 772 deaths per day. However, with school back in session cases are increasing again even as reported testing is decreasing – test positivity is up from 4.8% to 6.1%, and test volume is down below 600,000 tests. A majority of COVID-19 outbreak hotspots are currently college towns, which may or may not be correlation.

Tiny Antibody
A tiny bit of protein developed by University of Pittsburg researchers might be therapeutic and preventative against SARS-CoV2. Called Ab8, the immunoglobulin-based antibody neutralizes the virus at low concentrations and could be administered via nasal inhalation.

Mask Perceptions
A study in Germany found that mandatory mask policies might be better for everyone than voluntary.

We were wrong about masks – they DO protect me (not just you)!
This is still largely correlative, but there is data that suggests masks may help build immunity to COVID – meaning masks are much more than protection from you for those around you!

This Week in Science Questions!

“What is TWIS’s stance on the issue of transgender people existing? That’s probably not the best wording for my question, but I’m struggling to word this in a way that keeps it strictly a matter of science.

On the July 29 episode, there was a discussion of barriers to entry prescience were members of marginalized communities. In it, Blair talked about the impact on careers of raising a family, in which she described pregnancy and childbirth as “”What it means, biologically, to be a woman.””

I emailed her to point out that this ignores transgender men and nonbinary people who are capable of these things, in addition to cisgender women who cannot have children or don’t want any. I am open to the possibility that I misspelled Blair’s email, I have not received a response to my email or heard any acknowledgement or retraction on the show.

Then on the September 5 episode, after Blair’s store about the limb regenerative capabilities of anemones, there was discussion of the wish for humans to have that capability. Justin pointed out that alcohol and caffeine could have deleterious effects just like people experiencing pregnancy. That statement was perfect, but then he amended himself to less inclusive language by changing it to “”women experiencing pregnancy.

So you can understand my concern, and I wanted to know if you followed the lead of organizations such as the American Medical Association, American Psychological Association, American Academy of Pediatrics, Society for Adolescent Mental Health & Medicine, American Nurses Assocation, American Medical Students Association, American Osteopathic Association, and American Heart Association, or believe in the regressive idea that women are simply walking uteruses.

I’ve been a fan of TWIS for a long time, but could not in good consciousness continue to listen to the show if you deny the experiences of my friends, my wife, and myself.

Wherever in the world you may be.

Keep an eye out for something interesting.
Listen to a sound you might not otherwise pay attention to.

Look and listen.
Observe the world of nature.
Life in all its many forms evolved over billions of years
Overcame every possible earthly obstacle to exist.

Look and listen.
Observe the world of technology
accelerating our evolution first with stone tools
giving us the cutting ability of sharp claws that nature had overlooked.
And lastly with the ability to adjust the genome itself…
Influence if not control over our evolutionary future.

Look and listen to the subtle creatures and objects around you
And know that it‘s connected, all connected to observations made long ago,
And observations yet to be made by generation yet to come,
And all these observations, when backed up by a little knowledge

Let’s start with some quick science news stories…

Sleep & Stress
Researchers at Cold Spring Harbor Laboratory stressed out mice and kept them from sleeping just by triggering a few neurons.

Pain varies from state to state?
At least, opioid prescriptions do.

Plants know where the bodies are buried.
Plants could help point out to coordinates of deceased and missing persons, if we can just figure out how to talk their language, and differentiate dead humans from dead deer.

Arctic Jeans
Your blue jeans are everywhere. A study looking at the eprevalence of microfiberrs in sediments in the canadian Arctic, Laurentian Great Lakes, and shallow suburban lakes in southern Ontario found that not only are microfibers widespread, but blue jean fibers make up a large percentage. The results indicate that blue jeans are an indicator of pollution.

They just aren’t out there
10 million stars searched, no aliens found.

Mega Pixels
The biggest picture ever was just taken by researchers at the Stanford SLAC facility testing the camera for the Vera Ruben Observatory that is being built as part of the LSST in Chile. The equivalent of combining 189 16-Megapixel smartphones, this camera’s image was 3.2 billion megapixels of data. And, they used it to take pictures of romanesco broccoli.

Earth
It’s at most a medium sized planet with a lot of humans
Billions of them even
More humans than you are likely to run into on any other planet
And despite sharing the same star
Each one sees the world in a different light
For the most part we humans walk past each other
Seldom knowing how or what the other thinks about this or that
But every once in a while we cross paths with one of these humans
And we strike up a conversation…
And every once in a long while we find
That there is a another human who sees the world very much like we do
Has a similar ethic or aesthetic appreciation
Chases similar sparks of curiosity into the weeds of contemplation
Lighting up the conversations path like a lightning storm on a dry summer night
Ed Dyer, long time listener, contributor and conversation starter here on TWIS
Was one of those humans for me and for a lot of our TWIS family
His spark will be missed but not forgotten
As he has inspired many of us
To keep setting small fires to share our thoughts around
Add enlighten our paths as we walk this world together
Thank you Ed for being a big part of why we do
This week in science,

Black Hole Merger
LIGO/Virgo have confirmed the merger of two stellar mass black holes into a larger black hole of intermediate mass.

Bacteria merger
Evidence of bacteria not just swapping genes, but organelles has emerged.

Female scientists provide something special
It’s not their wiles.

Water Source
A new paper in Science argues against the idea that most of the water on Earth came from Cometary delivery. Instead, using a novel analysis of water concentration in meteorites originating in the inner part of the solar system, they find there was plenty of water in the stuff that made Earth, and that we don’t need to make up difficult scenarios involving Jupiter to give us a wet planet.

Insects are the future

“Hi Dr. Kiki,
I am a long-time listener and Patreon member to TWIS. When you started your your new segment with listener questions, it made me think about what I may have a question about. I started to think about the small things first: viruses, bacteria, amoeba, fungus, parasites, then I came across enzymes. I went on YouTube and watched a quick video that was way over my head. I realized I know 0% about enzymes. Do you mind giving some basics on enzymes and why they exist in our world?
Thank you,

As it contains factual information derived from science.
The topics, may include politically controversial topics such as:
Global warming

Panspermia and
Cuttlefish

If you have not previously been exposed to scientific knowledge
You might have a pre-existing belief in how the world ought to be
When confronted with facts that refute these beliefs most people change their minds.
Many continue to believe the thing not supported by science,
And a few die immediately.

“Hi Kirsten, Justin and Blair,

I’ve got a question for you and it’s something light and not even closely associated with COVID-19. Let’s take a bit of a break from this dark topic for a moment.

Here is the subject of my question.

As you can see, he / she (kind of hard to tell -:) ) is happy chomping liver sausages. I do follow Blair’s advice not to touch wild animals (yes, I imagine how terrifying it should be when somebody is several times bigger than you is touching you ?) but just can’t resist to feed these folks.

My question is for Blair – is it ok to feed them with liver sausages? It seems like they enjoy it a lot but I’d love to hear a suggestion of an ex zookeeper.

Thank you Blair and thank you Kirsten and Justin for what you’ve been doing and especially now, with so much of cra…I wanted to say disinformation in this world.

Researchers adept at revealing the secrets of the universe
The stories of planet earth
The mysteries of Life
And the systems by which life manages to survive on a planet
Spinning round a star
Spinning in a galaxy
Just one such galaxy out of billions hurtling through space.

While the significance of human achievements may be somewhat limited

The expanse of our knowledge need know no limits on
This week in science,
Coming up next…

Let’s start with some quick science news stories…

Take A Breath
When you breath, you probably think of breaths happening in your lungs. But, breathing really happens at the level of the oxygen-carrying heme-molecule. When heme holds oxygen it changes shape. New research has discovered that change in shape happens thanks to a cascade of electrons through the molecule.

Politicians use less words than they used to …
Fewer, more simple words in speeches

Holy sling-shotting spiders, Batman!
Nobody needs that…

Drunk Sensors
Researchers used accelerometers in smartphones to tell when people were drunk… had anofficial blood alcohol content of 0.08. They found side-to-side swaying was most highly correlated with alcohol intake, and hope to be able to design systems that could potentially work when a phone is in a pocket or purse.

Herpes cured!!!
Almost nearly anyway.

Eye Spots
A scientist painted eyes on cows’ rumps, and discovered that they were predated less often.

Now for the weekly COVID-19 Update!

COVID Update
Cases in the US are on the decline overall, although several individual states are experiencing continued or increasing spread. Generally, the trend suggests there should be a reduction in deaths appearing in the data in the next few weeks, which would be welcome considering we’ve been averaging over 1000 death a day for a while now.

People Coping
Older people with depression and anxiety were found to be more resilient than expected during this pandemic.

Face Shields
They shield people from COVD-19 infection.

Comparisons
A JAMA article compared the 1918 flu pandemic to the current COVID-19 pandemic, and found that aside from modern medicine and health parctices that are probably saving lives today, the two events are comparable. In fact, the current pandemic might actually be worse in some respects. But, we’re not going to discuss this too deeply tonight, since we will be talking with one of the study’s authors, Dr. Jeremy Faust, next Wednesday.

Convalescent Plasma
One new pre-print suggests it works, but without a control group it’s hard to make a truly convincing argument. The FDA has postponed giving convalescent plasma emergency use authorization until the results of this study can be fully reviewed.

Yeah, that’s the world’s second largest telescope, located in Puerto Rico and currently tracking that dangerous near earth asteroid five times the size of a football field, or 80 tennis courts if you prefer…
…what do you mean Arecibo got ripped in half by a busted tension cable?
Seems like there’s a good reason
To worry, worry worry…
But one thing about which you need not worry or fret…
Is this week in science,
Coming up next…

Let’s start with some quick science news stories…

Water Worlds
Where there is water there might be life. And, a series of papers in Nature this week support the idea that a salty ocean exists beneath the icy surface of Ceres. Data from the Dawn mission, which visited the dwarf planet in the asteroid belt, showed variations in the Texas-diameter planetisimal’s gravitational field indicative of pockets of saltwater. Additionally, high-resolution images tell a story of ancient impacts cracking the ice shell, allowing water to seep onto the surface where it is visible today. Dawn first imaged these white spots on Ceres surface in 2015. The finding implies that the conditions for life could be closer to Earth than previously thought.

Ancient alligators of North America
HAD GIANT TEETH!

Teeny tiny cleaners
Artificial polyps modeled after corals can take contaminates out of the water particle by particle. And soon, they could grab a single cell to help with medecine! And most people don’t even know corals are animals!!

Damaged Dish
In the middle of the night on August 10th, a steel support cable snapped at the Arecebo Radio Observatory. The tension release resulted in a 30-meter slice out of the telescope’s 307-meter dish and damage to a newer antenna addition, the Gregorian Dome. The telescope will be offline until repairs can be made.

Look-Alike Galaxy
12 billion years ago, a galaxy like the Milky Way existed. This is weird because we have never found anything quite as ordered that far back before.

Dolphin Age
Could we slow aging down if we knew what to look for? Scientists addressed this question by studying dolphins. After 25-years and 144 dolphins housed by the US Navy, we have four markers found in the blood that can be used to measure aging differences… in dolphins. Hemoglobin, lymphocytes, platelets, and alkaline phosphatase levels indicated faster or slower aging individuals. If these same markers apply to human aging, they could inform the development of treatments for things like age-related anemia.

Clean Your Mouth!
Just like sanitizing surfaces, perhaps sanitizing your mouth works to reduce SARS-CoV2 transmission.

COVID Air
A hospital study found viable virus in the air of hospital rooms up to about 12 feet from admitted patients. Samples from the patients and air matched genetically, indicating that infectious aerosols can get into the air even without intubation procedures.

This Week in Science Questions!

From Eric Combs:
“What has science done for me lately?
Well, I went on a trip to Munising, Upper Peninsula Michigan. Thanks to the hard research work of geologists, I was able to learn about geological strata back in college. Thanks to chemists and other scientists, we were able to learn about the elements, especially those we see in geology: iron, manganese, calcium, copper. What am I driving at? Well, for me, science can enrich and enhance the beauty of nature. Science does more than propel us forward technologically. It can also help us find new ways to activate our PNS to reduce stress and bring enjoyment to our existence. Everything from tiny arthropods to giant celestial bodies beyond our atmosphere. Yoga and body mechanics. Progressive relaxation and mindfulness. Science helps me appreciate the beauty everywhere around me, even in these tumultuous times of civil unrest and COVID-19. Knowledge is never a prerequisite for appreciating beauty, but it can help enrich the wonderment of everything around us. Science needs us to continue to explore the world each day with awakened curiosity.

Science question: If science wasn’t cool, then why is it possible to spell NErDy (nerdy) with the periodic table of elements? Nitrogen, Erbium, Dysprosium. Maybe the listeners would get a good chuckle?”

Disclaimer, Disclaimer, Disclaimer!!!

The following program might be considered politically biased because it is almost entirely science based…
We have not taken time to include the “other side” of the arguments.

We will often refer to the world as round knowing full well that there is still a robust argument
amongst a few individuals somewhere around the world,
who have a different view of how the universe works.

We will talk as if global warming is real and man made and getting worse,
despite the politicians with ties to the fossil fuel industry not being convinced.

We will talk about extinct life forms, ancient DNA, and evolution
without explaining that most of the world still entertains cartoonish children’s stories as its origin.

And we will talk about the very real threat from a pandemic virus…
We will not allow anyone here to call it a hoax.

Not when there is now 1 American death every 80 seconds from covid-19.
Wear a mask…
Wash your hands…
Stay home…
or better yet
Head for the hills, and don’t ever plan on coming back…

What ever you decide
Remember that if we all took the drastic step of doing nothing together
For just three weeks,
We would be done with it.
Instead, we are just beginning another episode of
This Week in Science,
Coming Up Next…

Let’s start with some quick science news stories…

Martian Ice Sheets
Using an algorithm taking into account erosion processes, researchers at the University of British Columbia and collaborators analyzed over 10,000 Martian valleys and compared them to subglacial channels in the Canadian Arctic Archipelago. They found similarities that led them to a new hypothesis that there were never free-lowing rivers on Mars, but instead river-like channels on the Martian surface were formed by meltwaters beneath ice sheets like those the used to cover much of Earth. The idea would be even more supportive of life on Mars, as thick sheets of ice would protect any microbial life from solar radiation and provide a more constant environment for growth.

3D Body scan can tell your athletic potential?
Maybe? Or, it might be good for helping you buy clothes that fit.

Happier cows
Cows perform social grooming, and studying that could help us make happier cows, healthier cows, and better milk and meat.

Sperm Spins
Apparently, sperm don’t swim. They spin. A new investigation of sperm motion determined that what we saw as a side-to-side beating motion under the microscope was actually an optical illusion based on 2D viewing. Sperm use 3-dimensional movement to drill, spinning their way to the egg like a top with the sperm body doing the spinning as the tail wiggles asymmetrically to one side.

Juno sparks new questions about Jupiter
How does that lightning spark?

Toxic Spider Webs
Orb weaver spider webs might contain neurotoxins! Christie Wilcox reports on a paper this week that reports neurtoxin-like compounds in the silk glands of banana spiders, which might allow them to weave webs of doom for their prey.

Now for the weekly COVID-19 Update!

COVID Update
According to the Johns Hopkins COVID Trackers, the US remains #7 in terms of per capita daily incidence and #1 in terms of total daily incidence. India is poised to surpass the US should we begin to decline. Also, the WHO data suggests a global plateau for daily incidence is emerging.

Kids Got Virus
Although they don’t present with symptoms as often as adults, a study looking at the viral load in various age groups with mild to moderate symptoms found that young kids often have as much if not more virus than adults. This doesn’t say anything about their ability to actually transmit the virus. Additionally, a separate study found that 10-20 year olds transmit virus as readily as adults. So, the picture of kids as viral petri dishes still holds.

Modelling School
Two studies modeled different scenarios for returning kids to school – one in the Lancet found that in the UK a substantial proportion of the symptomatic population would have to be tested regularly, and contact tracing and isolation implemented and strictly followed if schools are to reopen and not trigger a second wave. The second study in JAMA looked at college age students, and concluded that all students would have to be rigorously tested every two days to ensure safe campus re-openings at a cost of $470 per student per semester.

Complement Gone Awry
Lurking in our immune systems is an ancient power that today is understood as a a functional bridge between innate and adaptive immune responses that allows an integrated host defense to pathogenic challenges. While the proteins that comprise the Complement cascade are nominally part of the innate immune system, they can be recruited into action by antibodies. And, according to a recent study, this is potentially how the SARS-CoV2 virus is taking advantage of our immune systems – a survey of viruses discovered that coronaviruses tend to be mimics of complement and coagulation proteins. Another study published this week in Nature Medicine reports that people with age-related macular degeneration, who have an over-active complement system, are at increased risk of developing severe COVID-19. The finding suggests that drugs that work to inhibit complement proteins could have use in treating the disease.

Reversing Alzheimer’s
New drug targets in a mouse model lead to reversal of cognitive deficits. Will it work in humans?

Dr. Kiki’s got some science for you!

Natural Protection
In MS, the myelin sheath that protects nerves deteriorates and reduces nerve function. Scientists at the University of Edinburgh discovered a natural mechanism they are calling ARMD that protects myelin from damage when MS isn’t involved. That discovery led them to find a readily available diabetes drug that protects nerves from the damage of MS by enhancing ARMD.

Brain Limits
Could our brains ever be ramped up like in the movie Limitless? According to a study in the Journal of Neuroscience, the answer is no… unless we can figure out how to boost cellular metabolism.

This Week in Science Questions!

Kurt Larsen writes:
“Hope you folks are staying safe over there, both physically and mentally. We haven’t had a case in our state for a couple of weeks now, so fingers crossed!

My question for TWIS is that for the last six months there’s been a large increase in personal hygiene. From social distancing, to hand washing, to the use of sanitizer, or just staying home we’ve been exposed to less pathogens, and the drop in “”common”” diseases like influenza have been quite marked and measurable. And people are still having babies. Maaaybe more than usual later in the year. Hey, lockdown was boring right!

As you know the Hygiene Hypothesis is the idea that a decrease in exposure to microorganisms, particularly in children, leads to greater problems with allergies and immune diseases. I know time will tell, but do you think will we see more problems in the upcoming months and years, or will this be a worldwide experiment to disprove the theory?”
