Don’t put all your eggs in one basket.
Which, on the surface may seem like an unreasonable and deeply flawed idiom.
Yes, there’s the whole there goes the basket, so goes all the eggs…
But, if when collecting eggs from hens you attempted to carry multiple baskets
The risk of dropping a basket would obviously increase…
And how many of us actually collect eggs now days?
The modern equivalent might be, don’t put all your eggs in one shopping cart.
So, you’ve got a dozen eggs, you put six in this cart, and six in that one…
Still looks like the egg to cart ratio is off…
You now need a third cart…
4 eggs per cart, that seems a little less risky!
Unless you happen to be walking down an isle where someone else is attempting to push three carts
Because now the risk of being cut down at the Achilles by a shopping cart has gone up dramatically
When it comes to being a life form on planet earth, we are all in the same basket.
And until that changes we need to act like it.
Because where goes the earth, so goes all of us.
And nowhere is that made more obvious than

Uterine Influence
Considering last week’s story about uterus transplantation, this story on the effect of hysterectomy on rats is worth consideration.

Deep Life
The Deep Carbon Observatory, which has been assessing the carbon inside our planet, recently reported that there’s a lot of life down there.

Dark through the ages…
a dark matter tale of stability.

Spider milk: not just for babies…?
Spiders can give milk… And what’s more, mom continues to make it long after young can fend for themselves! Does that sound like anyone you may know??

Darwin’s finches are getting spoiled rotten
Junk food is changing the course of evolution, in one of the poster-children of Darwin himself.

Chicken Years
We are affecting the evolution of chickens in unexpected ways.

This Week in What Has Science Done for me Lately?!?
“Hello Dr Kiki,
I’m Elie (pronounced like Ellie but it’s a guy’s name). I’m from Lebanon and currently doing my PhD in Molecular medicine in Cyprus. my work is on the role of natural killer cells in Multiple sclerosis specifically when it comes to EBV infections. Being in a specialized virology lab, we rarely get to see or hear of science news outside our fields, that’s why I find TWIS such an essential part of my week, so much so that I’ve gotten in the habit of writing one of the topics I hear on the week’s TWIS. It’s found some fans who now enjoy my weekly TWIS update. Let me tell you what has science done for me: it has sparked my curiosity in the workings of everyday, it’s let me pursue my studies in a field that’s so vast and unknown, and most of all it’s allowed me to tinker in the working of biology, and dabble in other sciences outside of biology. So thanks for your hard work and enthusiasm. Much love to you, Blair and Justin!

Too many eggs in the Midwest basket
Climate change will have increasingly negative impacts on agriculture.

Your Brain On Imagination
Is just reality.

Information Mindset
Your attitude carries more weight than some genes.

Lipid membranes more organized than we imagined
Hexagons make them structured.

Supernova Death
Did a supernova kill off the Meg by giving it cancer?

Toothless whale does more than look silly
They tell us about the evolution of baleen!

they’re pretty much everywhere.
The following program is geared towards humans
Humans make up most of the listening audience.
The stories are mostly retold by humans,
Based on scientific work done by other humans.
There are humans helping record, edit, and rebroadcast the show.
There are humans who support the financial needs of the show.
There are even humans who visit the show from time to time.
But oddly, the actual content of the show is rarely directly about humans.
It’s one of the wonderful things about science;
Unlike most anything else we humans talk about…
Science allows us to focus our minds on things not human.
And as it turns out,
there’s a lot more going on in the universe than us!
And we’re going to talk all about it here on
This week in science,
Coming up Next…

CRISPR Babies Update
Apparently, the researcher who reported the first births of two gene-edited babies is now missing. Also, are we discussing the edited CCR5 gene, which according to research in individuals given CCR5 blockers ass part of HIV treatment is involved in learning and memory. So, tell us who was only interested in disease and NOT enhancement?

You, Me, Uterus!
The Lancet reports the first instance of a live birth from a transplanted uterus from a deceased donor.

Placenta In A Dish
Researchers in the UK have successfully created healthy placental organoids from donated placental tissue, which could lead to a platform for studying placenta-based disease in the lab.

Ancient mystery hominins somewhat discovered
Whose tools have we found?

If it walks like a dolphin…
it still isn’t a dolphin. It might be an Ichthyosaur!

This Week in What Has Science Done for me Lately?!?
“Hi Everyone,
Long time listener (Eric-in-AK in the chatroom)
What has science done for me lately?

Well, on November 30, 2018 my home, Anchorage Alaska was hit by a magnitude 7.0 earthquake. The epicenter was 7 miles from town. In other places an earthquake that big and that close has been devastating and deadly.

However, Alaska is earthquake country. We have a large percentage of the world’s earthquakes. So we have some history.

On March 27, 1964, Anchorage and South-Central Alaska suffered a mind-boggling magnitude 9.2 quake. This quake, known as the Good Friday Earthquake for the day it happened, caused significant damage and a large loss of life.

In 1964, after the arrival of relief workers and disaster supplies came scientists. They studied the ground that had been moved by the quake. They looked at buildings. They talked with eyewitnesses and in the end, they came away with a better understanding of earthquakes.

The ground movement offered confirmation of the then new theory of plate tectonics. The damage assessments lead to new tough building codes used throughout earthquake prone regions. And the rescue and relief operations lead to new and updated procedures to react to such a quake.

So, what has science done for me lately? Because of the scientific work done in the aftermath of the 1964 Good Friday Earthquake, my home of Anchorage just rode through a potentially devastating 7.0 earthquake with some, but not a lot of damage, no fatalities and only a few injuries.

Thank you, science.
(personal note, the quake was a wild ride)
–Eric Knapp”

Seven spiders spinning, four wiggly eels, three sneaky sharks, two water bears, a seahorse, and a liverwort plant…
New species for the holidays!

A Neuromorphic Synapse?
Are we on the path to artificial brains? A new study suggests nanowires with memristor abilities might finally be up to the task.

Galileo GPS system confirms Einstein’s Relativity!
Galileo satellites were poorly launched in 2014, their elliptical orbit allowed them to measure time dilation due to their change in distance from earth’s mass.

Greenland is going, going…
Melting due to climate change is happening at a much accelerated rate.

No Heart Stem Cells
To address the controversy surrounding the existence of stem cells in the heart, a recent study traced the paths of dividing mouse heart cells after induced myocardial infarction to see if any of them became new heart muscle. The result? While cells propagated new blood vessels, immune cells, and scar tissue, no new heart muscle was found.

OSIRIS-REx At Bennu!
NASA’s OSIRIS-REx mission arrived at the asteroid called Bennu this week, and is preparing to (technical term here) “boop” the chunk of space gravel to grab a piece and bring it back to Earth.

LIGO Virgo Catalog
The gravitational wave detector teams have released a full catalog of observations, which contain four additional black hole mergers based on deeper analysis of the data. The next observation season begins in Spring 2019.

Depending on how you arrived at this moment
you may have been told
that your existence was preceded by one or more of the following events…
A lump of clay fashioned just so
An extra rib put to better use
A delivery stork (that’s the one my grandmother told me)
A bolt of lightning into a pool of muck
A sperm an egg and an ancient ape
That you are simply made up of star stuff
As Carl Sagan once put it…
“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars.”
And while the answers to what we are made of and where we come from
are both mysterious to many and mostly known to science…
There are still gigantic questions left un answered
Often at the most minuscule of scales…
And tonight, we will find out once and for all, what some of those questions are
Here on
This week in science,
Coming Up Next…

Interview w/ Dr. Alex Himmel:
Dr. Himmel is an Associate Scientist at FermiLab on the NOvA and DUNE projects, and a Wilson Fellow, having received a 2017 DOE Early Career Research Award to optimize neutrino oscillation deciphering software. And, he’s been at this particle physics thing for a while now – he worked as a summer intern at FermiLab at the age of 16.

I asked on Twitter, and this is what you said:
“Let’s me listen to podcasts, follow creators on a tablet, and watch Stan Against Evil on my dvr.” –Grandfather Paradox (@papadiabolous)
“I’m alive due to brain surgery in the 60s” — Randy LaMonda (@randylamonda)
“Science helped me complete a Maillard reaxn to have a crispy golden brown turkey. Thank you science you’re the best.” –Mike Lowery (@MikeLowery5)
“Heat in the oven raised the temperature of the sugar & butter mixture I poured over the top of this Apple pie and caused it to carmelize into a nice crunchy coating! Science!!!” –Dean Segovis (@HackAWeek)
“Without science I would not live anymore. I had a hole between the upper chambers of my heart. After a 12 hour medical intervention, i could really breath for the first time in my life. Thats 47 years ago in the early 70’s.” –Burkhard Dunkel (@BurkhardDunkel)
“Lately? It has been helping me since my first vaccine for polio. My father’s bypass surgery and handling of diabetes, and delivery of my first baby and how painless it was for my wife, ability to contact anyone on the planet with simple hand gestures. What more could one ask?” –Sai Krishna Vajjala (@Krish_NCC1701)
“Science kept my food cold until it helped cook it. Stored food safely until needed. Lights my house. Takes me to the store. Keeps me alive. Before it was science it was magic and still did all those things.” –Jeff Coffey (jcoffey1138)
“Most recently science is allowing this conversation to happen.” –Roger Williams (@halfacat)

A Chinese researcher has been using CRISPR to edit embryos for HIV resistance. Apparently, twin girls have been born from this process. Independent analysis of the results is still pending, although the international community is in an uproar.

Climate Bugs
New species of bacteria have been discovered on the ocean floor that use hydrocarbons like methane as fuel, and might devour petroleum, too!

We really are all descended from star people
Or, at least people who looked at the stars.

Ah, let me sing ye a tale of whale ear wax
It’s a good thing whales don’t use q-tips, because that ear wax tells us a lot about life as a whale!

Zombie spiders, enslaved and eaten by wasps!
No, it’s not the latest horror film, it’s nature. Isn’t it beautiful???

Climate Assessment
The US government’s fourth climate assessment was released last week on Black Friday, and concludes that the US will sufffer major economic impacts if we stay the course on climate.

Mars Insights Coming
After its months long journey to Mars, the Insight lander successfully landed in Elysium Planitia on the surface of Mars, sent back some images, and is getting to work on science preparations. We should begin to see results within the next month as it will be drilling into the surface of the red planet taking temperature and seismic readings.

ION Drive
Because EVERYONE sent this to me this week… MIT researchers have succeeded in engineering the first aircraft (small though it is) to use no moving parts, and be powered by ionic wind.

Thanks to science, we now know how long it takes to pass a lego.
The answer: about two days.

Giving thanks.
That thing we do once a year
and then go about taking everything and everyone for granted all over again.
And at times, depending on where you are standing in the world,
when you look about it may be difficult to find things to be thankful for.
So here are a few starters…
Be thankful for friends and/or family!
Unless you haven’t got such folks in which case…
Be thankful for your good health!
Unless yours happens to be failing you in which case…
Be thankful for sunny days!
Unless you are in a drought in which case…
Be thankful for rainy days!
Unless you live in a flood plain in which case…
Be thankful that we are all at least safe from immediate danger
Unless we aren’t in which case, can I hide with you?
But the point is,
humans have been surviving for as long as there have been humans on the planet.
And if there is one thing we should all be thankful for this year…
It is that we humans are a resilient bunch of hairless apes.
That no matter what feast or famine of good times or bad are thrown our way.
We eventually make it to the other side.
And nowhere is the metal of our resolve or the determination of will and fierce glint of persistence in the eyes of humanity more blindingly apparent than right here on…

This week we here at This Week in Science are grateful for the science that allows us to podcast and stream, so that we can talk about science with you. We are grateful for scientists who endeavor around-the-clock to discover more about the world around us, so that we can calk about that science with you. We are grateful for those who shine a light on the failings of the scientific institutions, so that science may one day better represent the world around it, and so that we can discuss the improvements to science with you. We are also grateful to science for helping us all to live healthier, longer, more fruitful lives, so that we can share our lives with you. We are grateful that you share your time with us.

Artificial Pseudocells
UCSD researchers have created artificial cell mimics with several lifelike traits, like cell-to-cell communication and quorum sensing.

Active Mini-Brains
Scientists turned stem cells into brain cells, and then into mini-brains, which spontaneously began connecting and communicating thru electrical signals that were eventually comparable to the brain activity of preterm babies.

Living longer/better lives through mice
Young proteins rejuvenate old muscles.

When it rains…
it really does pour.

Did you know that wombats poop cubes? We thought we knew why, but now we might know how…
It turns out, it all comes down the the end of their intestines. But there’s still some mystery there.

Vitamin D – it does a baby good!
Vitamin D may be an essential part of all reproduction across the animal kingdom. Pregnant? Past due? Go get some sun!

Spider Silk Strong
The strength of spider silk can now be attributed to nanofibrils that make up the strands.

It’s all in your teeth.
How many babies you’ve had, or when you were pregnant, may be written in the rings in your teeth!

New Old Life
First identified in the 19th century, Hemimastigotes have been given their own branch in the tree of life thanks to molecular phylogenetic analysis.

Perspective is everything.
That said, and with some authority,
I will now state with an equally authoritative voice that…
Perspective is not everything…
It is true that there is a proper perspective for most situations that allows those things being perceived to be more manageable, more positive, more insightful, more inspiring or simply more informative…
And of course the opposite is true as well.
But a glass half empty or half full, contains the same amount of water regardless of your perspective.
A petri dish left out over a weekend could be perceived as sloppy lab work…
Following this perspective could lead to countless meetings on the best way to prevent such things from happening in the future, maybe followed by some dirty looks from fellow folks in lab coats for making them attend such meetings through no fault of their own…
Or, it could be seen as an experiment all unto itself.
What happens when you leave a plate of bacteria out overnight in the lab?
What were the results of this mistake-speriment?
This is of course the perspective that Alexander Flemming assumed when he discovered that something had attacked a bacterial sample mistakenly left out in his lab…
Regardless of the perspective that Flemming had happened to don that day…
The occurrence of a soil fungus finding its way to that sample would have been the same.
But because the proper perspective was assumed for the situation, the hundreds of millions of human lives were saved by the anti-bacterial properties of penicillin.
And while the following program promises to make you smarter, wiser, faster, taller, more tuned in, yet with an air of being a comfortably tuned out human,
all the while secretly developing within your inner fish brain a telekinetic ability to astral project your mind to a quantum dimension of synergistically organic yet digitally disruptive string of nonsense words…

Raining in the desert – it’s a bad thing.
Shifting climates cause odd flows of water, causing crazy things like heavy rain in the desert. That might sound like a good thing, but in fact desert microbes have much to fear from getting wet!

Your sperm hate climate change
Maybe climate change is finally hitting humans where it hurts? Right in the sperm!

It’s time to slow your carbon output.
The stock market may depend on it.

Primates of the Caribbean


Pollution creating a real 1-2 punch for insects
The molecules in air pollution are giving some plants a boost in their insecticidal tendencies, devastating insect populations. And that’s a bad thing…

Plastic poop
Plastic fibers found in fur seal poop, as a first in the wild. Can’t say it’s surprising, but it’s a good thing we’re working on it!

“Hi TWIS! I’ve written in before but wanted to share recently not only what science has done for me lately, but what TWIS has done for me lately! As an ecology student science does a lot for me every day. It’s the core of all of my course work and therefore I am constantly immersed in all of it’s awesomeness. Recently, I was given an assignment to give an oral presentation on any scientific topic of my choice. I was elated (as any nerdy scientists should be), as I ran home to play one of the more recent TWIS episodes for inspiration! As a wildlife ecologist, Blair’s animal corner is my favorite part of the show and I was especially intrigued by her stories about Sea Star Wasting Disease. I was even more intrigued when I heard that the most recent study discussed was conducted by UVM marine biologist Melissa Pespeni, because UVM is where I hope to do my graduate work! So, I found the perfect topic for my oral presentation. I dove deep into the world of Sea Star Wasting disease and learned all kinds of new and important information that I might never have stumbled upon had it not been for TWIS. So thanks TWIS, for inspiring my most recent assignment topic; and thanks science, for teaching me new things about the world every day!
Best wishes and good science,
Minion Carlee ?”

Not every moment that passes by us on the carousel of life seems important.
They all are,
they all could be championed to some degree or another,
each tic and every tock could be better engaged to accomplish great things.
But, for the most part they just seem to zip by unnoticed.
every once in a while,
we take on a moment together.
And when we do,
when we all take on a single moment with our collective focus
When we take action together.
We are more effective than any one of us can ever be alone.
I am of course speaking of science.
Though it may apply to other things as well.
Because the moment in which you can do is always now.
And that moment is here on…
This Week in Science,
Coming Up Next…

No More Denial
Well, at least for two years in the House… Democrats gained back the House of Representatives, and in doing so have taken back the House Committee of Science Space and Technology. Ranking member Eddie Bernice Johnson made a statement laying out priorities.

Bionic Mushrooms!
Scientists have engineered a symbiotic system out of photosynthetic cyanobacteria and mushrooms using 3D-printing.

Watching Whales from SPACE!
Our best chance at tracking and monitoring whales might actually be to use satellites. Yes, whales are THAT BIG.

Wanna find some piranha?
Take a listen! New technology will be able to find, track, and estimate population size of piranha just by listening. And I thought fish couldn’t talk!!

This Week in What Has Science Done for me Lately?!?
“Hey there, writing again over a year after my first entry about Hurricane Harvey.
Today I was sitting in my car, having just picked it up from being repaired after a parking lot fender bender, and was thinking how nice it was to have it back when the “What Has Science Done For Me Lately?” segment came on TWIS. I realized many of the reasons I liked having my own car back was due to science, because it’s a hybrid. Usually gasoline is a rare thought, I stop more at gas stations to grab something from the convenience store then I do to get gas. Even though the rental car was smaller then my hybrid, I was surprised how much I ended up paying attention to the amount of fuel in the tank. Also I found myself a little annoyed of what to me were the odd sounds in made in the parking garage at my apartment, as I’ve grown so accustomed to the near silence of my car running entirely off of battery power at low speeds. Additionally, my place of employment offers preferred parking for hybrid and electric cars, which means normally I get a space that is very close to the building. This week without my hybrid I had to search the far reaches of the parking lot for a spot, and more then once got drenched in the rain going to or from the further away parking.
So thank you Science, to all the chemists, material scientists, engineers, and many more, who make it possible for me to have a hybrid car that is I enjoy.
PS In the next year I plan I buying my own home, so unlike at my current apartment, I’ll have easy access to an electric outlet from where I park my car, which will allow me to get a plug-in hybrid or fully electric car when my current hybrid needs replacement.
–Jay Schneiderman”

Frogs Legs Forever
Using a pregnancy hormone, researchers have enabled the regrowth of frog’s limbs, and think they can make it work in humans, too.

This week in sea star wasting disease
The plot thickens, and it is all about the microbiome!!

Milky Way’s Black Hole
It exists!

Speaking of Holes
Astronomers reported discovering black hole mergers in multiple galaxies.

Elephant bird was blind as a bat
And by blind as a bat, I mean they had poor eyesight. Because they weren’t blind, just nocturnal. And also bats aren’t either…. oh nevermind……

Llama Bodies
Llama’s might help us fight the flu. Who knew?

Sliver Of Truth
It might be aliens, but that doesn’t mean it is.

This Week in What Has Science Done for me Lately?!?
“Dr. Sanford,
First I want to say how much I enjoy TWIS. I listen to several science podcasts — Naked Scientists and Guardian Science from the UK, Quirks and Quarks from the CBC, Science Friday (of course) & Undiscovered, Science from the AAAS, Science Talk from Scientific American, plus a couple of 60-120 second science sound bites. TWIS is my favorite. I hope you will have more interviews, and I would like to suggest that you create a separate collection of the interviews on the site to make it easier for listeners to find them and listen to them over again.

Over the years of listening (I remember when you were a doctoral candidate and podcasting from UC Davis), I have learned a great deal about multiple scientific subjects. One that particularly concerns me is my health. I am 72 years old and am fortunate in that I have no serious health problems so far. I am doing everything I can to keep my health for as long as possible.

I am particularly concerned about Alzheimer’s Disease. My mother was dying from it when she was my age now, and she died at 75. Last January on TWIS I heard about a study that showed that Tumeric taken in food (not as a pill) may be effective in preventing Alzheimer’s and curing early stages of the disease. Since then I have been doing myself daily by the simple method of adding it to my food at meals, including putting it on my morning toast. I also do calisthenics, inspired by studies that show that this can help with brain health, and I take long walks (5 miles plus) several times a week on the steep hillside I live on, during which I listen to TWIS and other podcasts.

The only problem I have with the tumeric is it gets on my clothes and stains them yellow. Now if science could develop a savfe, eco-friendly stain remover that would get those stains out I would be happy.

All the best to you, Jason, & Blair, and keep up the great work you are doing educating the rest of us about the latest progress in science.
Bert Latamore”

Brainy Birds
New Caledonian crows have done it again. Showed off their impressive avian intelligence by creating compound tools made of smaller components to solve a food-acquisition task. This ability arose late in human evolution, and is expressed in children around 5-years of age.

New clues about what killed the dinosaurs
Liquid land might have played a part after the meteor impact.

Extra-super-fast-ultra-broadband internet on the way…
Researchers have figured out how to untwist twisted light with a smaller device, making faster internet a near-term possibility.

Two parents are better than one
But mom often gets the short end of the stick…

Momma knows best
Mother chimps know which males they can trust, and which they should steer clear of. That’s a mother’s intuition!

Moss Medicine
Maybe moss will be better than weed for medical uses. A species of liverwort contains a compound similar to THC that binds to cannabinoid receptors, acts to reduce inflammation, and has less of a psychoactive effect.

Stressful Stink
People apparently release a compound called isoprene into the air when stressed, and it could be used as a metric to determine group stress level… and maybe movie ratings.

Do lizards dream?
Yes, but not quite the same as we do.

What’s brown, sticky, and terrifying? If you’re a bird, sticks are scarier than snakes, because their movement is just spooky…

Regardless of how many people have stated it in the past…
Ignorance is not bliss.
Yes there are things you cannot un-hear
Things you cannot un-see
And yes the world is full of totally regrettable and completely forgettable information…
It may even be safe to say that on any given day
There are more events worth forgetting than remembering.
By having a mind nimble enough to sift through the noisy informational wreckage of a sentient society
Separating the factual from the fictional,
the cement-able concepts from the dreadfully disposable…
Seeking out sources that are soundly scientific
And deep-sixing suspiciously un-skeptical concepts
Are not acts of ignorance…
But acts of reason and rational thought.
These are the actions of an advanced mind.
An advancing intellect.
And there is no more certain sign that you’ve got such a mindful intellect than the act of listening to
This Week In Science…
Coming up next!

My Two Dads
An effort to create embryos from stem cells taken from two male mice was unsuccessful, but teaches us much.

Life Questions
New physical evidence suggests claims of early life from rocks in Greenland might be faulty.

What makes stem cells so nervous?
The nervous system!!!

Goo For Growth
Salivary excretions from carrion beetles restructure the microbial community in decaying corpses, and support growth of beetle young.

Blind As A Bat?
Surprise! Bats have generally good vision, but cave-roosting and echo-location definitely led to tradeoffs in detecting UV light.

This Week in What Has Science Done for me Lately?!?
“This will be my second “”What has science done for me, lately? contribution.”

I was inspired by your trio of unanimous dishwasher machine adoration in a podcast earlier this year.

I am on the opposite end of the curve from you in that I grew up in a house with a dishwashing machine that I abhorred to such extent that I have not sought to use one as an adult. I wash my dishes by hand and, I feel, I’m extremely water and energy efficient.

I have recently moved to the dry continent of Australia from the verdant Willamette Valley where one had but to lean out one’s door to collect water. Here, where water is scarce, I am abundantly grateful for my science dabblings. I use two buckets for dish washing: one full of water and soaking dishes, the other is rinse water. Easy, water efficient, and, here’s the sciencey part, perfect for watering the garden.

Why? Because I am a kitchen witch and my lotions and potions are all made from mostly food. I make my own cleaning materials, balms, and toothpastes from kitchen cupboard items, so everything in my world is biodegradable, plant and animal friendly, and safe to consume in case one has wee kidlings or pets. I take my two big buckets of food debris and soap water from the sink and use them to feed my herbs and vegetables with zero concern about chemicals that kill. I just made two batches of lye soap, and some jars of beeswax salve to gift for holidays. I even make my own enzyme counter cleaner from citrus peels. I’m so happy that science allows me to take happy, healthy, mostly edible components and, through judicious application of heat and chemical reactions, create safe products that sprang from and are happily returned to our precious Earth.

Thank you, Science!

Tornado troubles
They are moving East!

Hurricane humblers
Maybe off-shore wind turbines can lessen hurricane effects on land.

Nicotine Nursery
Nicotine leads to behavioral and genetic effects generations down the line.

If You Can’t Quit
There is a solution on the horizon – Enzymes nix nicotine addiction.

Dead Rats
Researchers looked at dead rat remains to understand the differences between country and city rats of long ago.

Preserve Life Now
It will take millions of years for mammals to recover diversity losses that are currently occuring thanks to human actions.

Snow Song
The snowy layer covering the Ross Ice shelf in Antarctica influences the internal vibrations of the shelf, which sound ominous when sped up for us to hear.
