Carl Sagan on 'Cosmos'

Over the past few years, there has been a growing number of people who believe the Earth is flat. A 2019 YouGov survey of more than 8,000 Americans found that as many as one in six are "not entirely certain the world is round."

Flat Earth Theory has, surprisingly, gained a lot of traction. A 2021 study published in the National Library of Medicine posited that the theory is buoyed by "the cognitive tendency to interpret, favor, and recall information in order to strengthen one's personal beliefs" or, in other words, confirmation bias. Though the "how" and "why" of Flat Earth Theory and its popularity is fascinating (and troubling, to be honest), the scientifically proven truth is that the Earth is round. It is a globe. It is spherical.

Of course, the knowledge that the Earth is round is not new. Ancient Greek philosophers across centuries studied and found evidence that the Earth is indeed round thousands of years ago. Way back in the 6th century BC, Pythagoras first proposed the Earth was round from observing the shape of the Moon. In the 5th century, Empedocles and Anaxagoras noticed evidence of the Earth's true shape by observing its curved shadow during lunar eclipses. In the 4th century, Aristotle argued the Earth was round after noting how ships disappear "hull-first" over the horizon line. In the 3rd century, Eratosthenes actually calculated the Earth's circumference using geometry and shadows with shocking accuracy.

Naysayers remain skeptical, and there's probably no changing their minds, but to this day, experts insist the Earth is round and back it up with cold, hard science. NASA posted this video just days ago. Watch:

Here's where Carl Sagan comes in.

Sagan hosted the original version of TV's Cosmos: A Personal Journey in 1980-81. According to PBS, Cosmos would become "one of the highest-rated programs in the history of public television" largely due to Sagan's ability for "reinterpreting intricate scientific jargon into elegant and memorable statements that the common person can easily conceptualize and appreciate." The show would be revived in 2014 with astrophysicist Neil deGrasse Tyson at the helm.

In the first episode of Cosmos, Sagan easily proved the Earth was a sphere using a piece of cardboard, some sticks, and the work of none other than the ancient Libyan-Greek scholar, Eratosthenes. Watch:

"How could it be, that at the same moment, a stick in Syene would cast no shadow and a stick in Alexandria, 800 km to the north, would cast a very definite shadow?" Sagan asked. "The only answer was that the surface of the Earth is curved," he concluded. "Not only that, but the greater the curvature, the bigger the difference in the length of the shadows."

Considering the distance between the two cities and the lengths of the shadows they produced, Eratosthenes was able to determine that the Earth had a seven-degree curve. He used that calculation to speculate the Earth was 25,000 miles in circumference.

These days, we know that the earth is 24,901 miles in circumference, which means Eratosthenes was less than 100 miles off. Didn't we say his accuracy was shocking? Not bad for over 2,000 years ago.

7 mindblowing medical breakthroughs that could occur in our lifetime

One day soon, you might be able to grow new teeth. Seriously.

My family has a history of Parkinson's Disease, so I always see the headlines that promise some major scientific breakthrough in regards to the disease based on small, lab-based experiments or trials run on animals. They give us a glimmer of hope but, far too often, these treatments never see the light of day. The road from promising idea to having a real treatment available for patients is extremely long and arduous. Most potential new medications and therapies don't survive.

But... things do sometimes happen! There are massive medical breakthroughs being achieved all the time. Sometimes it's a new discovery, sometimes it's a successful clinical trial, and sometimes it's the fruit of all that labor finally becoming publicly available to people who need it the most. For example, an RSV vaccine just became available in 2023 for the first time. A powerful non-opioid pain killer was approved in 2024. A new drug came out to treat schizophrenia that was completely different than anything that had come before. Progress is being made every single year.

In our lifetime, say the next five to 20 years, we could see unbelievable advancements in treating certain medical conditions. Here are a few pretty amazing potential developments that are on the horizon.

1. Growing new teeth

Unlike sharks, humans are known to grow only two sets of teeth, our baby teeth and permanent adult teeth. If one gets knocked out or lost due to decay or infection, you're out of luck!

But researchers say growth buds exist in our gums for a third set, and scientists in Japan have had success in activating them to grow naturally. It could be a major gamechanger that could one day replace dentures and prosthetics. The team has moved onto human trials and has a target date of having a drug ready by 2030.

2. Cancer vaccines

Medical scientists have made amazing strides in cancer research, especially in the field of vaccines.

Did you know that lung cancer is considered to be the most deadly of the bunch? A lung cancer vaccine could be available very soon. If a cancer vaccine sounds odd, think of it this way: Cancer can be treated by chemotherapy and radiation, but there's always a chance of it coming back. People who have survived cancer could theoretically take the vaccine and massively improve their chances of reoccurrence.

A similar vaccine is showing promising results in clinical trials for pancreatic cancer.

3. Better treatment for Alzheimers

Alzheimer's Disease is one of the most destructive and heartbreaking conditions imaginable. It's also extremely difficult to treat, with most currently available therapies and medications focusing on slowing or temporarily relieving certain symptoms.

One new avenue scientists are exploring is a vaccine that could target a protein called tau, which clumps together and tangles up crucial neurofibers that deliver information in the brain. One such medication aims to activate a patient's immune system and produce "a strong antibody response against both pTau and its harmful aggregated form." The drug was recently fast-tracked by the FDA and has shown promising results in human clinical trials.

Another relatively new development is the availability of monoclonal antibody treatment, which helps slow the progression of the disease. Currently, the treatments are not particularly cost-effective but may become moreso in the near future.

4. Breakthrough treatment for Huntington's Disease

Huntington's is a fatal central nervous system disorder that shuts down key brain functions in patients like speech, walking, and cognitive function. Some of the symptoms can be treated but, so far, little can be done to slow or stop the progression of the disease.

However, a new drug known as PTC518 was recently fast-tracked by the FDA due to promising results in clinical trials. It attacks mutant Huntington protein in blood cells and in cerebrospinal fluid and has been shown to improve symptoms of the disease in a 12-month trial run. What's especially exciting is that this drug attacks the disease itself rather than just treating symptoms at the surface level.

5. Targeted viruses that kill antibiotic-resistant bacteria

Bacteria is getting smarter and evolving. Antimicrobial resistance is a grave threat to the global population as well-known antibiotics become less effective against infection and new antibiotics are expensive and difficult to develop.

(If you've ever dealt with a staph infection, you know how scary it is when drugs just... don't work.)

This is where special viruses, called bacteriophages or just phages, come into play. These viruses selectively target and kill bacteria, and were actually first used about 100 years ago. Scientist are coming around to using them again. In select settings, they've proven to be incredibly effective against resistant infections, but will need more testing before they become widely available. However, it's definitely possible that this become a viable alternative to antibiotics in some cases in the next few decades!

6. Synthetic and bioprinted organs

There are simply not enough donor organs going around for all the people who need a healthy liver, heart, or kidney.

Luckily, incredible strides have been made in creating artificial organs that can function like the real thing. A man in Australia just lived for 100 days with a titanium heart while he awaited a transplant! And bioprinting technology – quite literally 3D printing using real tissue and living cells — has the potential to create new working organs from scratch in the near future. Genetically modifying animal organs to function in humans temporarily or maybe even permanently has also come an extremely long way and is a process that will drastically improve in the coming years.

7. A one-pill cure for Hepatitis B

Hepatitis B is a potentially fatal infection of the liver that affects hundreds of millions of people worldwide. There is a safe and effective vaccine available to some people, but it's only preventative and won't treat active infections.

A research team in Israel recently discovered that a low dose of well-known chemotherapy drug, Curaxin-137, completely destroyed a crucial and mysterious protein that the Hepatitis virus depends on. The testing was done in a lab setting, so the next step is clinical trials. The team hopes that one day in the not-so-distant future, patients could take a single dose and completely eradicate the virus in their system. That's about as close to a miracle-cure as you can get!

Not all of these potential breakthroughs will come to fruition, but it's pretty amazing to dig into the advancements and discoveries that are being made every day. This list is just scratching the surface, to say nothing of robotic surgeons that will make major surgeries less invasive, new treatments for baldness, nanotechnologies that can deliver medicine to specific parts of the body, and more. Ultimately, good news is coming relatively soon for people who need it.

The 2023 Comedy Wildlife Photography Awards.

The Comedy Wildlife Photography Awards, known for being one of the most entertaining photography contests, has just wrapped up, and this year’s top prize goes to Jason Moore for his hilarious and brilliantly captured photo of a kangaroo, cheekily named “Air Guitar Roo.” Not only did this fantastic shot win the overall competition, but it also rocked the Creatures of the Land category, too.

Jason's photo stood out among a whopping 5,300 entries submitted by 1,842 photographers from 85 countries. Moore’s photo of the female western grey kangaroo was taken in the outer suburbs of Perth, Australia when Jason visited a field of wildflowers to snap some pics of the many adult kangaroos and joeys playing there.

“The shoot turned out to be a great session, and I am quite fond of several images that I captured,” Moore said in a statement. “Not many people know that kangaroos are normally fairly docile and even a bit boring most of the time if I’m honest. However, when I saw this roo striking the air guitar pose, it immediately brought a smile to my face, and I knew that I had captured something really special."

The Comedy Wildlife Photography Awards was started in 2015 by Paul Joynson-Hicks MBE and Tom Sullam to create a competition focused on the lighter, humorous side of wildlife photography while assuming an essential role in promoting wildlife conservation.

Here are 14 of the big winners.

"On this day, I had been out with my camera photographing some waterfowl at a nearby lake. I had been up at sunrise to take advantage of the 'golden hour' light, but it turned out to be a disappointing morning on the water. After leaving the lake, somewhat dejected, I decided to swing past an area of open bushland, because there are often a 'mob' of Kangaroos feeding and sunning themselves in a field close to the road. ... The morning light was still favorable so I grabbed my camera and headed off to a spot where I could get down to eye level with my subjects. I ended up shooting about 40 or 50 frames of the kangaroos with various content including mum’s, joeys and also some action shots of them bouncing along through the yellow field. The shoot turned out to be a great session, and I am quite fond of several images that I captured. However, when I saw this animal strike this pose it immediately brought a smile to my face and I knew that I had captured something special." — Jason Moore

"At RSPB Bempton Cliffs, each year between March and October, around half a million seabirds use the chalk cliffs towering above the North Sea to nest and raise a family. Gannets mate for life and they return to the same nest year after year to raise their young. Lying safely at the top of the cliff face, I was able to observe the affection shown between the gannets each time one returned to the nest. They have a greeting ritual, they rub beaks and entwine their necks; it’s how they strengthen their bond. But it’s also a brilliant opportunity to catch them in various poses. I didn’t realize I’d taken this image until I got home, but as soon as I saw it I laughed out loud! They look like proud parents, posing with their baby." — Zoe Ashdown

"While I was working deep in the Virginian woods, a family of grey foxes took up residence under the deck of the abandoned cottage next to my work housing. One day, while practicing their hunting skills on bits of moss and branches, one of the kits lunged at a small chunk of wood and started rolling around with his prize. Tired after his hunt, the kit lounged on his belly still holding the wood in his mouth which gave the strong resemblance of a cigar." — Dakota Vaccaro

A mouse attempts to revive an unconscious friend.

We do the animal kingdom an enormous disservice when we believe that specific characteristics are limited to our species. Throughout history, it’s been assumed that humans were the only creatures on Earth to exhibit empathy, rational thinking, consciousness, and the ability to use tools. But the more we learn about other species, the more those assumptions have fallen by the wayside.

A new study from the University of Southern California shows that when a mouse encounters another unconscious mouse, it will aid the mouse in a way that resembles human CPR. The researchers accidentally observed this behavior while studying why a mouse’s tongue protrudes under anesthesia.

“They start with sniffing, and then grooming, and then with a very intensive or physical interaction,” Li Zhang, a physiologist at USC and one of the study’s authors, told New Scientist. “They really open the mouth of this animal and pull out its tongue.” The mice were also found to lick the anesthetized mouse’s eyeballs and bite its mouth as part of the care behavior. In more than half of the interactions, the mouse pulled the tongue out of the unresponsive partner to clear the airway. “If we extended the observation window, maybe the success rate could be even higher,” team member Huizhong Tao told New Scientist.

Do mice give CPR?

The behavior looks a lot like CPR, but researchers are careful not to anthropomorphize or assume that the animal is behaving as a human would. Zhang says the behavior is more of an attempt to wake the unresponsive mouse up as if he were using smelling salts or a slap to bring them to consciousness. However, they believe that tongue repositioning is done to ensure the mouse’s airway is clear.

The study also found that mice familiar with the unresponsive mouse are more responsive to the animal. This could show that mice care more for those they are familiar with than those they have never met. “These findings add to the evidence that an impulse to help others in states of extreme distress is shared by many species,” neuroscientists William Sheeran and Zoe Donaldson wrote in a commentary accompanying the study.

The behaviors were driven by the release of oxytocin in the amygdala and hypothalamus regions of the brain. The hormone is associated with caring behaviors in various vertebrate species. James Burkett, a neuroscientist outside of the study research group, says that the release of oxytocin in the mouse’s brain is evidence of an “altruistic impulse” that appears to be born into mice.

The caring behavior exhibited by the mice has also been found in other species. Dolphins have been known to bring an ailing member of its pod to the surface for air when sick or injured. Elephants are known to support wounded or ailing relatives.

This study is another reminder that the line between human and animal intelligence and emotions is far blurrier than we think. The evidence continues to show that even species as small as mice—a species we call pests—have a natural impulse to help one another. The more we learn about the animal kingdom, the more we need to reconsider the uniqueness of many characteristics we call “human.”
