Appendix Cancer Has Rise Among Millennials and Gen X

by Ayelen Flores, age 15

Doctors and researchers have identified differences in the rates of appendix cancer depending on age group. Older age groups have significantly lower rates of developing appendix cancer: people born in the 1940s have rates of appendix cancer two to four times lower than people born in the 1960s to 1980s.

The appendix is a finger-shaped pouch attached to the large intestine. Appendicitis is a very common infection that causes inflammation of the appendix. To treat appendicitis, most go through surgery.

Appendix cancer has been a prevalent topic in recent medical conversations. There is also a gap in knowledge on appendix cancer that causes it to be misinterpreted as colon or ovarian cancer. Doctors can identify appendix cancer with symptoms such as stomach pain or bloating; these symptoms are different from appendicitis because they are unbearable and last longer. [Read More]

City of Monona Adopts New Rules for Vape Shops

by Will DeFour, age 15

A new ban on vape and tobacco retailers in Monona recently took effect.

Monona’s new ordinance states that vape shops may not be within 750 feet of schools, other vape shops, or city parks. This ban comes after several tobacco retailers opened in the city over the last few years. About 3% of middle schoolers report they have used vapes, and nearly 8% of high schoolers have used e-cigarettes. These are dangerous drugs for anyone to consume, but especially young people.

Vapes and e-cigarettes typically contain a chemical called nicotine, an addictive drug that can lead to the use of regular cigarettes, affect learning, and harm brain development. For this reason, nicotine can only be sold to adults 21 or older. Yet, young people still find ways to get their hands on vapes. [Read More]

Lessons From the 1918 Spanish Influenza Pandemic

by Ruben Becerril, age 13

In the 20th century, there was a pandemic that infected a third of the world’s population: the Spanish influenza.

Spanish influenza was a pandemic caused by influenza A (H1N1). While the name may lead you to believe it originated in Spain, the exact origin is still debated, with cases first identified in the United States in early 1918. It was only called Spanish influenza because Spain, which was neutral during World War One and not subject to wartime press censorship, was one of the first countries to report openly about the pandemic. In contrast, other nations at war limited public discussion of the illness. This influenza A strain caused common flu-like symptoms, but also hemorrhaging, skin discoloration, and severe lung damage. The illness infected an estimated 500 million people worldwide and killed at least 50 million people, with deaths occurring on every continent.

Influenza spreads through the air from person to person, and the virus can last in a room for several hours. An infected person can “shed” the flu virus for up to a week. The pandemic quickly spread throughout the world, and with no antiviral medication, no influenza vaccine, and a shortage of doctors due to the war, the virus spread rapidly and killed easily. Unusually, most of the people who died were young adults. Some theories suggest that because young adults had not been exposed to a similar influenza strain, their immune systems were unable to defeat it. Another theory suggests that their immune systems overreacted to the virus, causing it to damage healthy tissue. [Read More]

Africa’s Donkeys are Being Slaughtered for Medicine in China

by Owen Ayite Atayi, age 16

China’s demand for a traditional medicine known as e-jiao is fueling the slaughter of millions of donkeys every year, say animal welfare groups and veterinary experts. E-jiao, which is made using collagen extracted from donkey hides, is the vital ingredient in food and beauty products believed by many Chinese consumers to enrich the blood, improve the immune system, and prevent diseases. Reuters spoke to more than a dozen experts, including veterinarians and academics, to examine how demand for e-jiao is rippling across communities in Africa, which rely heavily on the donkey, and how the trade in hide continues to boom despite efforts by some African nations to restrict it.

Traditionally, e-jiao was a luxury product. It gained favor among elites during the Qing dynasty that ruled China from 1644 until 1912. Its popularity has surged in recent years due partly to its use in the Chinese television series ‘Empress in the Palace’, which started airing in 2011. The rise in demand has also been fueled by China’s growing middle class and rising elderly population. Its price has leapt 30-fold in the past decade from 100 yuan per 500 grams to 2,986 yuan ($420), according to Chinese state media. The e-jiao industry requires an estimated 5.9 million donkey skins annually, which has put unprecedented pressure on global populations, according to a report released in February by The Donkey Sanctuary, a British charity devoted to the animal’s welfare. China’s donkey population has fallen more than 80% to just under 2 million from 11 million in 1992, prompting its e-jiao industry to source donkey skins from overseas.

The consumption boom for e-jiao has led to international commodification of donkeys, says Lauren Johnston, an expert on China-Africa relations who published a study in January last year called “China, Africa and the Market for Donkeys”. As Africa has the world’s largest donkey population, it has emerged as the key source of donkey skins. [Read More]

How the Brain Stores and Retrieves Memories

by Dellany Onyango, age 9

A memory is a record of information that your brain considers important and saves. Memories can last five seconds or five years. Three parts of the brain help with memory: the amygdala, the cerebral cortex, and the hippocampus.

The hippocampus, located in the cerebral cortex, is the part of the brain that stores memories. An undamaged memory gathers information like the current day or time and retains it for later use. When the brain receives data, it decides which pieces are important. This process involves three steps: encoding, storage, and retrieval.

Encoding is when your brain takes in information from your environment and converts it into a form that can be stored. Then, your brain stores that encoded information for future use, which is called storage. The final part of memory is retrieval, which brings stored information back out of storage in three ways: recall, recognition, and relearning. Recall involves actively remembering something without environmental cues. Recognition occurs when your surroundings trigger your memory. Relearning happens when you remember information faster and more easily the second time you learn it. [Read More]

Why Fish Owners Should Watch for Fin Rot

by Lucas Abiy, age 8

Pet fish owners may want to dive in and learn about fin rot. It is one of the most common diseases in fish.

Fin rot is a disease that both saltwater and freshwater fish can catch. It is caused by different types of bacteria, most commonly Aeromonas, Pseudomonas, and Vibrio. Fish can develop fin rot when bacteria enter through a tear or injury in their fins or tail. A fish is more likely to catch fin rot when it experiences stress. Stress weakens the fish's immune system and allows bacteria to more easily take over. Fish can become stressed when their tank is overcrowded, when water quality is poor, or when they are bitten by an aggressive fish.

The symptoms of fin rot include frayed or ragged fins, often with black, white, or even red edges. In more advanced cases, the rot can spread toward the body. Other symptoms can include changes in behavior, such as lethargy or lack of movement. [Read More]

New Street Drugs Make Opioid Crisis Worse

by Moore Vang, age 15

Dane County and Milwaukee County health officials are concerned about a synthetic drug that can worsen the opioid crisis. This drug is known as medetomidine, an animal tranquilizer that is being mixed with fentanyl along with other street drugs. Although medetomidine has not been linked with overdose deaths in Wisconsin, it has been in other places nearby such as Chicago and is an example of the dangers of these new incoming drugs.

Medetomidine has multiple health side effects including sedation, decreased heart rate, and difficulty breathing which can worsen with opioid and non-opioid sedatives. These effects are similar to another animal tranquilizer that has entered Wisconsin: xylazine, also known as Tranq. Effects of these drugs can not be treated by opioid-reversing drugs such as Narcan, thus overdose is a serious risk when these drugs are present and abused.

Dr. Ben Weston, the director of medical services for the Milwaukee County Office of Emergency Management, said, “It makes opioids even more dangerous and harder to reverse.” Within two years, xylazine went from not being a concern to being the cause of 5% of all overdose deaths in Wisconsin. “The trends that we are seeing nationally probably mean that it’s only a matter of time until we see medetomidine here in Milwaukee County and in Wisconsin,” Weston said. A Milwaukee County medical examiner is continuing to look for the presence of the drug in overdose deaths. [Read More]

Cone Snails Deadly Venom Holds Promise for Medicine

by Siwoo Park, age 12

New research on cone snails and their venom has opened doors for possibilities in medicine.

Cone snails are ocean-living mollusks that have a hollow, spear-like, harpoon tooth to hunt prey. These harpoon teeth are laced with a venom that is made of molecules called peptides.

Cone snails have hundreds of subspecies. They inhabit almost all oceans and feed on fish, worms, and other snails. The snails’ harpoons pierce through their prey and paralyze them, allowing the snail to devour their catch. Even though most of these subspecies eat smaller prey, there are a few whose venom is strong enough to kill a human. [Read More]

The Science of Lucid Dreaming, Exploring the Sleeping Mind

by Dayanara Flores, age 16

The experience of knowing you're in a dream while you're still asleep is called “lucid dreaming.” Most people don't have lucid dreams, but some have tried techniques to become more self-aware in their sleep while dreaming.

Some lucid dreamers can control particular parts of their dreams like the setting.

Martin Dresler, a neuroscientist in the Netherlands who works at the Donders Institute says, “The special thing about lucid dreaming is that you can get even closer to dream content and in a much more controlled and systematic fashion.” Tests from small groups have found that lucid dreamers can also send signals to researchers while they’re asleep.

Event Highlights the Dangers of Vaping

by Elim Eyobed, age 13 and Ayelen Flores, age 13

Public Health Madison Dane County recently hosted an open-house event at Warner Park Community Recreation Center. The goal of the event was to raise awareness about vaping and its risks for young people. The event focused on the medical research and useful facts about vaping.

The creativity of local high schoolers was featured, in the form of three vaping awareness posters. The posters are a product of a two-year project that was a joint effort between Public Health Madison Dane County (PHMDC), UW-Madison Extension, and Madison teens.

At the event, the posters took center-stage, but were accompanied by various educational “stations” that highlighted what the students learned during the project. The first stop was a timeline of tobacco use, advertising, and legislation, dating back to 6000 B.C. and its use in ancient Native American communities for healing and tradition. The timeline included the creation of the first widely recognized vape, the Juul, and the recent spike in vape and e-cigarette use among youth. [Read More]

Marie Curie Was a Trailblazer in Science and Radioactivity

by Siwoo Park, age 12

Marie Curie, one of the world’s beloved scientists, was a pioneer in the study of radioactivity and her discoveries revolutionized cancer treatment. Through her discovery of radium, she became the first woman to win a Nobel Prize in two different fields, and eight years later won a subsequent prize.

Marie was born Marya Sklodowska on November 7, 1867, in Warsaw, Poland. She earned good grades and was even awarded a gold medal in her high school. Despite being a great student and her family valued education, she could not attend university because Russia had invaded Poland and women were not able to go to college after the invasion. Marya made money by giving private tutoring lessons and became involved with a group of young people who taught themselves their topics, called the “Floating University.” She became a governess to a wealthy family, but she craved knowledge and became more determined than ever to attend university.

In 1891, Marya went to live with her sister Bronya in France. She changed her name to a French variation of her name, “Marie,” and studied mathematics, chemistry, and physics at the Sorbonne, where she became the first woman to teach. In 1894, she needed a laboratory to work on her chosen study of measuring the magnetic properties of steel alloys. Her colleagues suggested she meet Pierre Curie at the Schools of Physics and Chemistry. Marie was astonished by Pierre from their very first meeting. [Read More]

The Greek Demigod who Became the God of Medicine

by John Agbo, age 13

In Greek mythology, the most powerful gods, known as the 12 Olympians, could not bring back the dead. Only Asclepius, the god of medicine, could. However, Asclepius wasn't always a god; he was born a demigod.

Asclepius was the son of Apollo and Koronis, the god of the sun and a mortal, respectively. In some myths, his mother abandoned him as a child and left him to be raised by a dog and a goat. His father, Apollo, raised him and taught the young demigod the secrets of medicine. Asclepius was tutored by Cheiron, a wise centaur and the teacher of many legendary heroes who lived on Mt. Pelion.

In some myths, Asclepius married Hygeia, another god of health, but in others, she was his daughter, and he married Epione instead. Asclepius had two sons and four daughters. His descendants, known as the Asclepiads, also carried on his legacy of medicine. [Read More]

LED-Embedded Bandages: A Bright Future for Wound Care

by Amelia Pearson, age 13

There is a big difference between normal bandages and future LED-embedded bandages. Modern bandages are currently being developed at the University Of Southampton in England. These bandages can stop microbes from reproducing and can also kill the microbes.

These bandages are ingrained with scaled-down LED bulbs emitting UVC wavelengths, usually used for cleaning medical equipment. The UV light replaces the antibiotics often used to kill germs.

The bandage needs a battery to power the lights being emitted, so the thought of wireless powering was seen as the most practical. With wireless, will minimize the harmful chemicals coming from thrown-away batteries. [Read More]

Dumb Phones on the Rise as Gen Z Looks to Limit Screen Time

by Allison Torres, age 15

Flip phones became popular in the 1990s and 2000s. At that time, they were a great invention in communicating with people wherever and whenever.

Over the years, phones have advanced technologically, which can be seen in both positive and negative ways. In 2007 smartphones came along, replacing flip phones with iPhones and Androids.

Smartphones have many advanced features like cameras, GPS, and many more applications, that can incorporate your data. This incorporation of personal information concerns people about their data being collected, shared, and used by companies. [Read More]

The Coming Invasion of Wild Pigs

by, Theodore Morrison, age 16

Pork, a delicacy enjoyed by many, is derived from the flesh of pigs. However, some wild pigs prove easier to capture than others. More specifically, a particular crossbreed between a wild Eurasian boar and a domestic swine possesses survival skills, a large body, and extreme fertility, rendering it nearly impossible to eradicate.

These pigs present a significant danger to humans and our food sources. Equipped with strong snouts, they excavate food from the ground. Unfortunately, they are not selective about their diet and are willing to destroy and consume crops, and wildlife, or even pose a threat to humans. Compounding the issue is an estimated population of 6 million of these pigs in the United States, causing concern among state and federal officials. In essence, these pigs pose a severe threat to our agricultural system and must be eradicated.

The United States has not turned a blind eye to these perilous creatures, prompting responses from Montana and Minnesota. Montana has prohibited the raising or transportation of wild pigs while endorsing preventative measures against these specific invasive animals, including surveillance. The U.S. Department of Agriculture has also implemented surveillance to assist in addressing the issue, while Minnesota plans to revise its management plan to better counteract the threat posed by these aggressive pigs. Moreover, many states have banned hunting these pigs due to a low success rate and the resulting increased wariness, causing the pigs to become more nocturnal and harder to track. [Read More]

The Profound Effects of Music on the Human Brain and Emotions

by Aissata Bah, age 13

Music serves as a form of art and tradition, expressing a wide spectrum of emotions, including anger, amusement, and sadness. It wields a remarkable emotional power that can transform one's mood, evoke physical sensations, and trigger the retrieval of long-lost memories.

The human brain responds to music in profound ways. When we listen to music, various parts of the brain come into play, including the temporal lobe, amygdala, frontal lobe, cerebellum, and hippocampus. These brain regions are involved in processes related to memory, emotions, communication, and muscle control. They help individuals analyze the components of music, such as instruments, lyrics, and musical chords. Moreover, the brain can recognize harmonies and notes, grasp lyrics, and synchronize with the rhythm, giving rise to new emotional experiences.

Music holds a special place in the hearts of many people, offering both enjoyment and therapeutic benefits. According to the Berklee Music and Health Institute, music can open pathways to healing. It has been used as a therapeutic tool for various conditions, ranging from alleviating subjective distress in chronic pain syndromes to influencing the reward circuitry in addiction disorders, the psychomotor pathways in Parkinson's disease, and even the functional connectivity changes in autism spectrum disorders. In simpler terms, music can serve as a form of medicine for trauma, chronic pain, addiction, and conditions that involve a disconnection between the brain and the body. Remarkably, music therapy can provide strength to patients undergoing surgeries, chemotherapy, and other medical treatments due to its emotional effects. [Read More]

Doctors Transplant Pig Heart in Human Recipient

by Dayanara Flores, age 16

In a groundbreaking medical achievement, surgeons performed the second-ever pig heart transplant into a human. This remarkable surgery took place on September 20, 2023, at the University of Maryland Medical Center and was carried out by the same team responsible for the initial pig-to-human heart transplant.

The recipient of this pioneering procedure was Lawrence Faucette, a 58-year-old man facing a life-threatening heart disease and internal bleeding, which disqualified him from a standard heart transplant. Following the surgery, doctors reported that Faucette was able to breathe independently without requiring any external support.

This type of transplant is known as a xenotransplant, a procedure involving the transfer, implantation, or infusion of organs or tissues from non-human or animal sources into a human recipient. It's typically considered a last-resort option when a patient's condition is severe or life-threatening, leaving relatively untested treatments as the only alternative. [Read More]

Brain Wave Technology Could Help Assess Concussion Severity

by Kevin Chen, age 15

Researchers in Texas have discovered a new technology that could use brain waves to detect the severity of a concussion and compare injuries in a standardized way. Known as magnetoencephalography (MEG), this technology may offer a way for doctors to evaluate and quantify the seriousness of concussions by measuring brain waves, potentially indicating the healing progress of a concussion.

Primarily employed in planning epilepsy surgeries, MEG scans the brain for various frequencies of waves, including delta waves with a frequency of one to four hertz. Typically, a person's brain frequency falls within the range of 13 to 30 hertz, known as beta waves. Researchers observed that individuals with concussions exhibited unusual delta waves, leading them to consider MEG as a new avenue for concussion detection.

Currently, doctors use brain scanners like electroencephalogram (EEG) to record neuron activity. However, EEG cannot detect weak electromagnetic signals deep within the brain, whereas MEG can receive signals from any part of the brain's folds and grooves. The resulting MEG images provide significantly more detailed data on brain activity compared to EEG, offering more accurate insights into a patient's condition [Read More]

Can Ultrasound Waves Remove Microplastics from Water?

by Ayelen Flores Ruiz, age 13

Pollution has become a big problem in today’s economy. Microplastics are a type of pollution that is really small and barely visible yet they are found in our bodies, causing a lot of damage. Microplastics can contain toxic chemicals, viruses, and bacteria.

These plastic bits are an issue for humans and wildlife. These plastics are incredibly hard to see, even smaller than a sesame seed, and no more than five millimeters wide. The bits can be found in water, air, and foods leading to their accumulation in human bodies as resources are utilized. The materials within these bits can contain toxic chemicals. Additionally, both bacteria and viruses can attach themselves to the microplastic. Wildlife can also ingest plastic bits through drinking water from rivers or the ocean. [Read More]

Wisconsin's Long History of Schools for the Blind and Deaf

by Dayanara Flores Gonzalez, age 16

Most students know how to read and write, but these tasks are difficult or even impossible for students who can’t see or hear. Parents in Wisconsin have sent their visually impaired children to special schools to be educated since the 1800s.

Before Wisconsin was a state, citizens had already noticed that educational facilities for visually and hearing impaired children needed to be provided. In 1843, Increase A. Lapham petitioned Congress to give funds to build schools for visually and hearing-impaired children, but nothing was done to make a change. The institution first began in Janesville when private citizens decided to create the first state school for impaired students. J.T. Axtell, a graduate of the Ohio Institution for the Blind, arranged a village meeting explaining several methods to teach children with defective vision.

Thirty residents gave $430 to start a school and purchase construction equipment. In October 1849, eight visually impaired students attended the first school for the impaired in the state, held in a private home. They asked the Legislature to help fund their school, and landmakers approved. The school tax-supported a budget of $2,500 to keep the school running in its building. [Read More]

Lone Star Ticks and the Allergic Reaction to Red Meat

by Valeria Moreno Lopez, age 17

Tick bites are a common nuisance in the U.S., but in the last 13 years, certain ticks have caused a severe and puzzling food allergy. Lone star ticks, commonly found in the Southeastern U.S., can transmit alpha-gal, a sugar that triggers an allergic reaction to red meat and mammal products like dairy and gelatin.

While alpha-gal syndrome is not typically fatal, it has affected an estimated 450,000 Americans, leading to intense reactions. Symptoms may not be immediately apparent, taking hours to manifest after consuming mammal products. Some common symptoms include hives, breathing difficulties, severe stomach pain, nausea, dizziness, and facial swelling. It's possible to experience any one of these symptoms, and if they occur, it's essential to seek testing. Certain factors, such as exercise, alcohol consumption, and the use of anti-inflammatory drugs like aspirin and ibuprofen, can make individuals more susceptible to the allergy after a tick bite. Those concerned about their sensitivity to red meat can undergo yearly blood tests to check antibody levels against the sugar.

Dr. Scott Commins, a researcher at the University of North Carolina, who has written about alpha-gal syndrome for the Centers for Disease Control and Prevention, has suggested that it could be the 10th most common food allergy in the U.S. While the allergy can subside in one-fifth of those affected, it's crucial to avoid tick bites, as reinfection can prolong the syndrome. Alongside tick avoidance, experts recommend dietary adjustments and carrying epinephrine, a hormone that treats severe allergic reactions. It's important to note that not everyone bitten by ticks will develop alpha-gal syndrome, but studies indicate a higher likelihood of development if the bite is scratched. [Read More]

The Scientific Explanation Behind the Enjoyment of Horror Movies

by Dayanara Flores Gonzalez, age 15

In 2002 the horror film The Ring came out. For some people, this film was too frightening to be fun. Many question why people find enjoyment in scary movies.

Margee Kerr, a sociologist at the University of Pittsburgh in Pennsylvania focuses on recreational fear; Kerr says that watching horror movies increases activity in the nervous system. Another researcher named Mathies Clasen surveyed more than 250 American horror fans to find out why they enjoyed watching horror films.

Once the responses came back, they revealed that there were three types of fans: the first group was called “Adrenaline Junkies” who said that, “being scared made them feel alive.” The next group was named “White Knucklers”. These people reported negative reactions to scary movies. The last group was the “Dark Copers”, who use horror as a coping mechanism for bad feelings and events that they experienced in real life.

Understanding the Health Impacts and Controversies Surrounding Daylight Saving Time

by Ayelen Flores Ruiz, age 13

Although daylight saving time is very popular with many people, it may have negative health effects for humans, according to some scientists.

Daylight saving time is when clocks move an hour forward in the spring and return to standard time in the fall. This makes people lose an hour of sleep, causing scientists to question if this is healthy. Kenneth Wright, an expert on sleep and body clocks, says that daylight saving time is the wrong name for this procedure. He says that humans are only changing the way they live concerning the sun, making their bodies out of sync. The action of changing the clocks creates a problem with the human body’s circadian rhythm as it resets. [Read More]

Investigators Find Child Labor Violations in the Meatpacking Industry

by Hanna Eyobed, age 17

Meatpacking factories are violating labor laws and exposing children to dangerous chemicals, federal labor investigators found. Kids as young as 13 have faced dangerous exposure to chemicals used to clean biohazardous substances in Nebraska, Missouri, Minnesota, and Wisconsin.

In Wisconsin alone, 50 illegally employed minors were hired under the supervision of the Packers Sanitation Service Inc. (PSSI). Upon investigation by the Labor Department, the PSSI was placed under review by a federal judge. The Labor Department also found 31 underage workers in three plants owned by the companies JBS and Turkey Valley Farms in Nebraska and Minnesota. Other underage employees have been identified in Arkansas. A 13-year-old who used to clean the JBS plant every night in Grand Island, Nebraska suffered a serious chemical burn from what was used to clean the plant. Other teens working at the plant stated that “everyone there knew '' that they were minors, according to investigators. The Labor Department has been comparing school records with employee rosters to find underage workers.

It’s part of a larger investigation of PSSI’s more than 700 locations and other meat-packing companies in the Midwest. “This case should serve as a stark reminder for all employers that the U.S. Department of Labor will not tolerate violations of the law, especially those that put vulnerable children at risk,” said Michael Lazzeri, regional administrator of the U.S. Department of Labor, Wage and Hour Division.

The World’s Population is Now 8 billion

by Jonah Smith, age 13

If you looked up on Google how many people were on Earth, the answer would be 7.8 billion people. But according to a recent United Nations report, in late 2022 our population finally hit 8 billion. The population is still rising, but the rate of growth has slowed. The rate the U.N. based their last predictions on was the rate of growth from 2017. At that time, the U.N. predicted that the world’s population could reach 11.2 billion people by the year 2100. With this new data, the population is now expected to peak during the 2080s at 10.4 billion people. Once it peaks, the numbers will plateau until 2100.

This new information also highlights the challenges linked with population growth, said Maria-Francesca Spatolisano of the U.N. during a news conference on July 11th, 2022. These challenges include meeting people's social and economic needs (food, water, shelter, etc.), as well as how people use Earth’s resources and alter the environment. [Read More]

To Stop the Spread of Dengue Fever, Scientists Infected Mosquitoes with Something Else

by Samuel Garduño, age 14

Aedes aegypti, the mosquito that carries the deadly dengue virus, began as a forest insect in the sub-Saharan part of Africa, but one lineage evolved to enjoy the urban environment. Transported through slave ships, these mosquitoes have traveled globally for centuries, carrying viruses like dengue. Today, dengue is recognized by the World Health Organization as a top ten global threat. Dengue infects around 390 million people and kills about 25,000 individuals annually. Dengue may be a lethal virus, but there’s a solution: Wolbachia.

The bacterium Wolbachia was discovered in 1924 in a different mosquito species, but it wasn’t until the 1980’s that scientists realized its astounding ability to spread and to control the dengue virus. Mosquitoes carrying Wolbachia can’t be infected with dengue, thus helping to prevent the spread of the deadly virus. With equal importance, Wolbachia spreads quickly among mosquitoes. It allows an insect mother containing the bacteria to produce more abundantly and pass the bacteria to her offspring. Therefore, Wolbachia is a fast and effective method of combating dengue. The bacteria is also an eco-friendly and non-toxic method of controlling dengue; it doesn’t even kill mosquitoes! [Read More]

Astronauts Face Bone Weakness While in Space

by Moore Vang, age 13

Astronauts may want to prepare for their next space mission by bringing exercise gear for their legs.

When astronauts spend time in space, they undergo some loss of internal support in their bones. This leads to the bones becoming thinner than before taking off into space. Space trips that last at least six months are equivalent to about 20 years of aging through bone loss. However, a new study shows that a year back on Earth rebuilds about half the strength originally lost in the affected bones. Leigh Gabel, an exercise scientist at the University of Calgary in Canada, says that “bones are a living organ” and that the bones in our body are “constantly remodeling.” Gabel was a part of a team with 17 astronauts who spent from four to seven months in space. Their team used a certain type of a CT or computer tomography scan to show the bones in their bodies, which was used to measure the structure of their bones on a fine scale. They focused primarily on the structures of the lower leg and lower arm which showed details on a scale of 61 micrometers.

The astronauts took images of the bones in the lower arm and leg four times: once before they took flight, when they returned home, and then again six and 12 months later. From each of those photos, Gabel’s team could determine the bone strength and density. A year after returning to Earth, astronauts that went to space for fewer than six months regained all their bone strength they had before taking the flight. However, those who stayed longer in space suffered more permanent bone loss in their shin bones. Surprisingly, the lower arm showed almost no loss, likely due to the bone not being weight-bearing, unlike the lower leg bones on Earth. Instead, arm bones get stronger in space than on Earth because astronauts rely on exercising their arms by pushing off handles and doorways in space. [Read More]

Fake Medicine, Real Results

by Moises A. Hernandez, age 17

The placebo effect, as doctors call it, is something that creates a real and positive change in a person's body but cannot be explained by the characteristics of the placebo itself. Something as simple as a father saying to a little girl who fell and bumped her knee, “I’ll kiss it and make it better,” can make the girl forget her pain.

With just a puff of air, a kiss, or a few kind words, a loving person can stop the pain of a child. Even though it should have no effect, a real change happens in the person’s body. That is why placebos are vital in medical research. In clinical trials, for example, a pill that contains no medicine but looks just like one with medicine is given to some participants. Researchers do this to show that people who are actually taking the medicine get better compared to those who really are not, therefore proving that a new medicine works.

“Placebos don’t do anything for bacteria,” Kathryn Hall, a medical researcher at Brigham and Women’s Hospital said. “Placebos can’t fight cancer. They can’t fight viruses.” [Read More]
