These humped heroes sure know how to beat the heat. As a heat dome scorches much of the U.S. this week, it’s a good time to learn about an animal who wouldn’t mind these temperatures at all. Camels are Earth’s largest desert-dwelling animals. While most desert animals evolved to be small so that they could escape the scorching heat by burrowing or seeking out slivers of shade, camels took a different approach. They evolved large, portable energy-conservation tanks in the form of humps.
Contrary to childhood legends, camels’ humps don’t actually contain water. Rather, they’re full of fat, from which their bodies draw energy throughout long treks in the heat. This allows them to eat and drink very little while on the move. In fact, camels can survive around a week without water and several months without food, even while walking up to 20 miles a day in scorching temperatures.
Camels are part of a group of animals called ungulates, most of which are hooved. Camels, however, have soft foot pads with two large, hard toenails. Though there are seven species in the family Camelidae, only three are commonly called camels: the dromedary camel, Bactrian camel, and wild Bactrian camel. Dromedaries have just one hump while bactrains have two, but that’s not the most important difference between them. Dromedaries are a completely domesticated species, while some bactrian camels still remain in the wild, living mostly in northwestern China and the Gobi Desert in southwest Mongolia. While bactrains are critically endangered, dromedaries are fairly common, making up about 94 percent of Earth’s camel population.
So, why domesticate camels? For people living near deserts, it makes perfect sense. Dromedary camels can comfortably carry up to 330 pounds over long distances, and even more during short trips. Humans can comfortably ride them, which makes them invaluable for crossing areas where roads are scarce. Camels can also be used for milk and even meat, making them one of the most versatile domesticated animals around. That’s not to say that all dromedaries live a sheltered life. Central Australia is home to a sizable population of feral dromedaries, whose ancestors were brought to Australia by 19th century European settlers. As an invasive species, they’ve caused some harm to local wildlife by eating native plants and drinking valuable water that native animals need to survive. A hunting program allows for a certain number of these feral camels to be killed each year, but their population remains fairly large. Some dromedaries are just determined to walk on the wild side.

You just can’t beat this heat. This year’s summer is getting off to a brutal start for much of the U.S. as a heat dome stretches over multiple states. Heat domes are defined by suffocating heat and humidity which have a synergistic effect and make it feel even hotter than it actually is. While heat domes can cause heat waves, the two meteorological phenomena are not the same. The source of a heat dome’s elevated temperatures and humidity is a lingering high-pressure system in the atmosphere that prevents heat on Earth’s surface from rising. The high pressure comes from the jet stream after it weakens and deviates beyond its normal course. Until the jet stream corrects itself, the heat dome will continue to persist, and the longer it lasts, the worse it gets. Because the high pressure also prevents cloud formation, the sun’s rays beat down on the ground, making the heat dome hotter over time. Temperatures can easily exceed 100 degrees Fahrenheit, and it can feel tens of degrees hotter. Sometimes, a heat dome will dissipate after just a few days, but they can last for weeks.
In 1995, a particularly devastating heat dome claimed over 700 lives in the Chicago area in less than a week. Even worse, a heat dome over the southern Plains back in 1980 claimed around 10,000 lives. Part of what makes a heat dome so dangerous isn’t just the heat itself, but the humidity, which makes it impossible for sweat to effectively wick excess heat away from our bodies. When a heat dome forms over a given area, it’s best to avoid venturing outside. The best policy is to stay in a climate-controlled area and drink plenty of water until the heat dome dissipates. Some problems are better avoided than faced head on.

FREEMusic Appreciation Song CurioFree2 CQ
Why is the biggest summer hit of 2025 from 1962? The power of social media. TikTok has recently fallen in love with Connie Francis’s Pretty Little Baby, a song that was never even released as a single. In fact, until recently it was a fairly obscure, B-side song, recorded by Francis as part of a marathon four-day studio session in 1961. But TikTokers saw the song’s potential as a backing track to aesthetic content—especially fashion-focused videos showing off romantic clothing, jewelry, and makeup. The bouncy tune’s lyrics are all about beauty, youth, and young love, and the instrumentals even feature a fairly modern-sounding synthesizer, putting it firmly in line with the needs of young TikTokers. Lyrics about meeting at the “car hop” and “pop shop” are just chic vintage icing on the cake. As for Francis herself, she’s charmed by the song’s belated success. In a post on Facebook, the singer thanked TikTok for its appreciation, and admitted that she didn’t know what the term “viral hit” meant until now. Hey, you don’t need to know all the ins and outs of social media when your content is this good.

Chromosomes are fundamental to creating life, but you can have too much of a good thing. Just one extra copy of chromosome 21 is responsible for causing Down syndrome, which itself causes many different health problems. Now, scientists at Mie University in Japan have developed a way to remove the extra chromosome using CRISPR technology. The chromosome responsible for down syndrome is called trisomy 21. When someone is born with this chromosome, they end up with 47 total chromosomes, rather than the usual 46. This results in a range of health effects, including congenital heart problems and cognitive issues.
Until recently, genetic disorders like Down syndrome were considered untreatable, but medical advancements have been changing things. Back in 2023, the FDA approved Casgevy and Lyfgenia, both of which are cell-based gene therapies to treat sickle cell disease (SCD) in patients over age 12. The treatments were developed using CRISPR-Cas9, which utilizes enzymes to accurately target parts of the DNA strand responsible for the disease. It’s the same technology used by the scientists at Mie University, who targeted trisomy 21 in a process called allele-specific editing, or, as one of the researchers described, “Trisomic rescue via allele-specific multiple chromosome cleavage using CRISPR-Cas9 in trisomy 21 cells.” The process was performed on lab-grown cells which quickly recovered and began functioning like any other cells. It’s unlikely that this new development will signal an immediate reversal of Down syndrome, as it will be a while before the treatment can undergo human trials. One particular hurdle is that the treatment can sometimes target healthy chromosomes. Still, it shows that CRISPR-Cas9 can be used to remove entire chromosomes and that cells affected by trisomy 21 can make a full recovery with treatment. That’s a lot of medical advancement in one crisp swoop.

Are you fluent in fans? Ornate fans have been used for centuries by wealthy ladies to look and keep cool. It has even been claimed that some women used them as a clandestine way to communicate. The picture above shows a silk and ivory folding fan in its open state. The fan is gold-colored and features intricate floral embroidery. Serving as a fashion statement, a show of wealth, and simply a means to stay cool, fans were an indispensable part of an 18th-century lady’s wardrobe. They were important conversation pieces at high society parties and social gatherings, often featuring luxe fabrics or even gemstones. However, some myths began to develop around the mystique of the versatile accessory, claiming that there was a secret “language” of fans used to send messages to lovers on the sly. For example, presenting a closed fan supposedly meant “Do you love me?” while drawing it across the cheek meant “I love you.” The “language” was really invented by a fan maker to boost sales, and there’s no evidence that anyone ever used the codes, but it allowed the fan to maintain an allure that persists to this day. Today, the main thing a fan conveys is, “Someone needs to turn on the air conditioner.”

They may be small, but they’re no saplings! The Brooklyn Bonsai Museum is celebrating its 100th birthday by inviting the public to learn more about the ancient art of bonsai, which has roots that go beyond just Japan. Bonsai involves growing trees in containers, carefully pruning and maintaining them to let them thrive in a confined space. When done properly, a tree kept in such a manner will resemble a full-sized tree in miniaturized form and not just look like a stunted specimen. Experienced practitioners can also guide the growth of the trunk and branches to form artful, often dramatic shapes.
Bonsai has been gaining popularity in the U.S. in the past century, and its history goes all the way back to 8th-century China, when dwarf trees were grown in containers and cultivated as luxury gifts. Then, in the Kamakura period, which lasted from the late 12th century to the early 14th century, Japan adopted many of China’s cultural and artistic practices and sensibilities, including what they would come to call bonsai.
For a tree to be a bonsai tree, it has to be grown in a shallow container which limits its overall growth while still allowing it to mature. While most bonsai trees are small enough to be placed on a desk or table, it’s not really the size that dictates what is or isn’t a bonsai. As long as it’s grown in a shallow container, a tree can be considered bonsai. In fact, there are some downright large specimens that dwarf their human caretakers. A category of bonsai called “Imperial bonsai” typically ranges between five to seven feet, but the largest bonsai in existence is a sixteen-foot red pine in Akao Herb & Rose Garden in Shizuoka, Japan. Bonsai trees can also live just as long as their container-free counterparts. The oldest currently in existence is a Ficus Retusa Linn at the Crespi Bonsai Museum in Italy, which is over 1000 years old and was originally grown in China, presumably before the practice even spread to Japan. If this tree ever falls—in a forest or not—you can bet that someone’s going to make a lot of noise.

What does the fall of Napoleon have to do with dentures? More than you might think. Napoleon Bonaparte was defeated at the Battle of Waterloo this month in 1812 by a military alliance consisting of Great Britain, the Netherlands, Prussia, and Belgium, ending with a whopping 50,000 casualties. The historic battle was a terrible time to be a soldier, but it was a red letter day for looters in search of teeth. Before the invention of synthetic materials, most dentures and other dental prostheses were made from actual human teeth and other natural materials.
As incredible as it might seem, the history of dentures and dental prosthesis dates back all the way to the ancient Egyptians. Archaeological finds supporting their advanced dental techniques include gold filled teeth and false teeth found buried with the deceased. Much of what is known about Egyptian dentistry was actually preserved by the ancient Greeks, who learned from them. Greeks, too, used gold to fill cavities as well as gold wire and wooden teeth to create bridges. Even the Etruscans, an ancient civilization that flourished in northern Italy that predates the Romans, were capable of creating dental prostheses. These include some of the earlier examples of dental bridges made of animal teeth held together with gold. The Romans were no slouches either in the dentistry department. There is written evidence that ancient Roman dentists were able to replace missing teeth with artificial ones made of bone or ivory, using methods similar to the Etruscans. Archaeological evidence also shows that they were capable of creating a complete set of dentures in this manner.
Unfortunately for those suffering from missing teeth throughout history, there were few significant advancements in the field of dental prosthesis for centuries after the fall of the Roman Empire. Teeth continued to be made from animal teeth, bones, or ivory with precious metals as the base to hold them together. Dentistry as a whole wasn’t particularly respected as a profession, and so its associated duties often fell to barbers and blacksmiths as supplementary work. Things began to slowly improve starting in the 1700s. In 1737, the “father of modern dentistry” Pierre Fauchard, created a set of complete dentures held together with springs. Fauchard was also the first to suggest making false teeth out of porcelain, though he never got around to it himself. Of course, there’s a popular myth that George Washington, who lived around the same time as Fauchard, had wooden dentures, but that’s entirely false. Washington wore dentures made from both human and animal teeth, which used ivory and lead for the base. Some believe that the origin of the wooden teeth myth comes from Washington’s affinity for Madeira wine, which stained hairline fractures in the false teeth, giving them the appearance of wood grains.
Until the mid-1800s, human teeth continued to be the standard for dentures, often bought and extracted from those desperate for money or looted from graves or battlefields. When Napoleon’s army was defeated after a bloody battle at Waterloo, survivors, locals, and professional scavengers descended on the piles of corpses and pulled as many teeth as they could to be sold to denture makers (though they often skipped the molars since they were hard to pull and would likely need reshaping).
Luckily, the practice of using human teeth eventually fell out of fashion, partly from legislation regulating the commercial use of human bodies, and partly from the advent of porcelain and celluloid teeth. Also in the 1800s, the newly developed rubber compound called vulcanite replaced the metals and ivory that formed the base of most dentures. Today, dentures are made from advanced materials like acrylic resin that closely mimic the look and function of real teeth. Modern dentures make even those from a few decades ago seem primitive by comparison. One thing’s for sure: high-tech teeth are a lot better than looted ones.

Spaun just won the U.S. Open by sinking a 64-foot birdie putt, and the only thing more shocking than that distance is the fact that it didn’t break any records. In fact, despite his superhuman feat, Spaun doesn’t even break the top 20 when it comes to longest putters. Spaun’s 64’ 5” putt is bested by Nick Dunlap’s 64’ 11”, which rests at 22nd place. The top ten doesn’t even start until Cameron Young’s 71’ 2” putt, which also took place at the U.S. Open (though it didn’t secure him a dramatic victory at the 18th hole, as Spaun’s putt did). The top five starts with Taylor Moore’s 80’ 5”, and continues with Roberto Díaz (80’ 11”), Jose Luis Ballester (86’ 8”), Ryan Fox (91’ 7”), and finally, with Patrick Fishburn’s longest-ever putt at 105’ 8”. On the other end of the spectrum, one might think that Jon Rahm’s infamous one foot miss at the 2022 Arnold Palmer Invitational is the shortest missed putt ever put on television, but that unfortunate distinction goes to Tom Whitney, who whiffed a three or four inch putt in 2023 during the Korn Ferry Tour. Even pros sometimes look green on the green.

This isn’t your grandma’s ice cream…unless she happens to be a native Alaskan. Akutaq, also known as Alaskan ice cream, is one of the most unique frozen foods in the world. Although it resembles ice cream, as its nickname suggests, it is savory and involves no dairy. It includes plenty of animal fat, though.
Akutaq is a traditional Alaskan dish enjoyed for centuries by different groups of peoples native to the region. It is made by mixing ice, often from freshly-fallen snow, with berries, meat, animal oil, and whipped animal tallow. Tallow is made by melting fat and then cooling it into a solid, waxy substance. Whipping the tallow gives it a lighter, fluffier texture. Different Alaskan animals can be used to make akutaq, including caribou, seals, moose, or fish. The dish is traditionally mixed in an ovular, wooden bowl called a tumnaq.
No one knows which group of native Alaskans first invented akutaq. It is most often attributed to the Yupik people, who are indigenous to both Alaska and Eastern Russia, since the name “akutaq” means “mix them together” in the Yup'ik language. However, other Alaskan peoples, including Inuits, also make akutaq, and since recipes were traditionally passed down orally, it’s unlikely that we’ll ever know exactly how it came to be.
What we do know is what it was used for: quick energy for long journeys. Unlike actual ice cream, which is considered a sweet treat and nothing more, akutaq is serious business, providing protein and fat that is much-needed before long expeditions through the snow. Since many native Alaskan peoples were nomadic, moving from place to place throughout the year in order to follow herds of prey animals, long treks in cold weather were inevitable. Akutaq helped ensure that everyone had enough energy and strength to make the trip. The ingredients could also vary widely based on where people were at any given time. Before particularly long journeys, akutaq might include dried meat for added protein, while akutaq made near coasts included more fish and seal meat. It might not come on a cone, but there’s no doubt that this frozen dish is more useful than ice cream.

It seems they’re turning red meat into read meat. According to a paper published in Scientific Reports, scientists at São Paulo State University (UNESP) have identified genetic markers that are associated with higher quality meat in cows. Current, conventional practices can only do so much when it comes to producing quality beef. At the end of the day, and all else being equal, livestock producers rely on the breed of cattle to do the heavy lifting. Even then, quality can be inconsistent between individuals thanks to phenotypic variability. But the researchers at UNESP appear to have cracked the code while working with Nelore cattle, a breed of zebu which make up around 80 percent of the cattle raised for meat in Brazil. By collecting samples from 6,910 Nelore carcasses after slaughter and grading, they managed to identify specific markers that are responsible for marbling (the amount of intramuscular fat), subcutaneous fat thickness, and muscle development. One particularly interesting discovery involved a gene responsible for heat shock proteins, which can influence meat tenderness by affecting fiber degradation after slaughter. The tenderness of meat can vary greatly between individuals depending on how much the gene is expressed. While similar efforts have been made before, including by the researchers at UNESP, this study was uniquely able to produce results by taking a more comprehensive look at the biology of individual animals. As the first author of the study, Gabriela Frezarim, explained, "The group had already made significant progress using different 'omics' [genomics, transcriptomics, and proteomics] approaches, but it became increasingly clear that no single technique is sufficient to understand the complexity of the biological systems that control variation in meat and carcass quality.” It’s like herding scientific disciplines together.

FREEBiology Daily Curio #3102Free1 CQ
Telling people apart is as easy as breathing. Researchers recently found that the pattern of a person’s breathing may be unique to the individual, much like their fingerprints. Currently, there are only a few surefire ways to identify someone: fingerprints, eye scans, and DNA tests. Soon, another option might be available in the form of breathing. Researchers at the Weizmann Institute of Science in Israel hypothesized that a person’s breathing pattern might be unique to them, and tested the idea with the help of 100 participants. The participants were equipped with special devices that tracked their breathing throughout the day, measuring the frequency and duration of each breath, along with the amount of air passing through their nasal cavities. Over the course of two years, the researchers entered the data they collected into a machine learning program, which learned to positively identify a person through their breathing alone with an accuracy of 96.8 percent.
There may be another use for this type of analysis besides identification. Researchers found that a person’s breathing revealed not only their identity, but information about their physical and mental health. People of similar body mass indexes share similarities in the way they breath, and so do those who suffer from depression or anxiety. Those with depression tend to exhale quickly, while those with anxiety have shorter inhales and pause their breathing more frequently during sleep. According to the researchers, their next step is to find out if and how breathing can be used as a diagnostics tool. In the future, they hope that it may even be possible to change peoples’ breathing patterns for the better. As Noam Sobel, a co-author of the study said in a statement, “We intuitively assume that how depressed or anxious you are changes the way you breathe. But it might be the other way around. Perhaps the way you breathe makes you anxious or depressed. If that’s true, we might be able to change the way you breathe to change those conditions.” We’ll be able to breathe easy, then.
