Watermelon is my favourite fruit. And I am not alone. According to a recent survey conducted by watermelon.org, around 79% of the world population likes the taste of this summertime fruit. But it's not just the juicy taste but also the nutritional benefits of watermelon that make it a fan favourite.

What's The Big Deal About Watermelons?

Watermelon is a hydration hero. With its high water content, is an excellent way to boost the body's hydration while enjoying a sweet treat. Its low-calorie density means you can indulge without worrying about calorie overload. Therefore, not only does this fruit provide hydration but also is ideal for weight management by keeping you fuller for longer.

Watermelon provides vitamins A and C, potassium, magnesium, and beneficial plant compounds like lycopene and citrulline. Lycopene, a powerful antioxidant, helps combat free radicals, reducing the risk of chronic conditions such as heart disease, diabetes, and certain cancers. Citrulline, an amino acid in watermelon, has been shown to improve exercise performance and enhance blood flow by increasing nitric oxide levels, which relaxes blood vessels and reduces blood pressure.

There is empirical evidence indicating that watermelons have the potential to cure cancer. Lycopene and cucurbitacin E, found in watermelon, may have anti-cancer properties. Research suggests that lycopene lowers insulin-like growth factor (IGF), a hormone linked to cell division. By regulating IGF, lycopene may help reduce the risk of cancers such as prostate and colorectal. Meanwhile, cucurbitacin E may support the body's ability to destroy cancer cells, though more human studies are needed.

Watermelon's nutrient content can also play a protective role against several heart diseases. It contains Lycopene which can reduce cholesterol levels and blood pressure, while citrulline improves blood flow. Nutrients such as potassium and magnesium in watermelon support overall cardiovascular health.

This juicy fruit can also help you live longer. The antioxidants, including lycopene and vitamin C, help counter inflammation and oxidative stress. Animal studies show that watermelon can lower markers of inflammation and oxidative stress, while human studies highlight vitamin C’s role in reducing inflammation.

Watermelon supports skin health with its high levels of vitamins A and C. Vitamin C boosts collagen production, keeping skin supple, while vitamin A aids in skin cell repair. Moreover, the pigment beta-cryptoxanthin in watermelon may reduce joint inflammation.

Moreover, watermelon could be a great option if you are feeling constipated. It has fibre that aids in regular bowel movements and water ensures smooth waste elimination through the digestive tract. This fruit is also good for your eyes as it reduces the risk of age-related macular degeneration, thanks to lycopene’s antioxidant and anti-inflammatory properties. Its citrulline content might alleviate muscle soreness and improve recovery after exercise.

How Much Watermelon Does The World Eat?

According to the Food and Agricultural Organization of the United Nations, a cultivation area of 3.2 million hectares was employed for the production of 103 million tons of watermelon worldwide in 2018. Asian countries contribute approximately 81% of the total production of watermelon worldwide. This summer wonder is not only consumed raw but also used for the preparation of smoothies, jams, sauces, candies, and juices.

A retracted eardrum, also called tympanic membrane atelectasis, is a condition where the eardrum gets pulled inward toward the middle ear. Normally, the eardrum (or tympanic membrane) acts as a boundary between the outer and middle ear, transmitting sound vibrations to tiny bones that help us hear. But when it collapses inward, that delicate process can be disrupted.

The condition is often silent at first, meaning people may not realize they have it. But in some cases, it can escalate, causing discomfort or even permanent hearing damage.

Spotting the Symptoms

In most cases, a retracted eardrum doesn’t cause any noticeable symptoms. But when the retraction becomes severe enough to affect structures inside the ear, individuals may experience:

• Earache
• Temporary hearing loss
• Fluid discharge from the ear

If left untreated, a chronic retracted eardrum can lead to permanent hearing loss.

Why Does It Happen?

The most common cause of a retracted eardrum is Eustachian tube dysfunction. These narrow tubes connect the middle ear to the back of the nose and help regulate ear pressure.

When they don’t work properly, pressure inside the ear drops, effectively pulling the eardrum inward.

Some common triggers include:

• Recent or recurring ear infections
• Cleft palate
• A poorly healed eardrum after rupture
• Enlarged tonsils or adenoids

Upper respiratory infections, such as the common cold

How Doctors Diagnose It

Diagnosis typically begins with a discussion about symptoms and any recent infections. A doctor will then use an otoscope, a tool with a light, to look into the ear canal. This allows them to visually confirm if the eardrum is abnormally positioned or collapsed.

Treatment Options: When to Wait and When to Act

Not all retracted eardrums require immediate treatment. In mild cases, doctors often recommend a “watch and wait” approach, as pressure may normalize naturally over a few months.

For more advanced cases, several interventions are possible:

Decongestants or nasal steroids: These can improve airflow in the ear and relieve pressure.

The Valsalva maneuver: This self-administered technique involves closing your mouth, pinching your nose, and gently blowing as if trying to pop your ears. It should be performed under medical guidance.

If the condition begins to affect hearing or causes persistent pain, surgical options may be considered.

Surgical Interventions

Two common surgical treatments are:

Tube Insertion (Myringotomy):

Often used in children with recurring ear infections, this procedure involves placing small tubes into the eardrum to help ventilate the middle ear.

Tympanoplasty:

In more severe cases, part of the damaged eardrum may be removed and replaced with cartilage from the outer ear. This stiffens the eardrum, preventing future collapses.

What’s the Prognosis?

The outlook largely depends on the severity. Minor retractions usually resolve without intervention and don’t cause long-term damage. However, more serious cases, especially those that persist or press against ear bones, may result in hearing loss and need medical or surgical correction.

Experts recommend seeking medical attention if you notice ear discomfort, hearing changes, or frequent infections. Early diagnosis can prevent long-term issues and protect one of your most important senses, your hearing.

In a surprising discovery that bridges the gap between creepy crawlies and cutting-edge neuroscience, researchers at Virginia Tech have identified unique compounds in millipede secretions that could pave the way for future treatments for pain and neurological diseases like Parkinson’s, depression, and schizophrenia.

Led by chemist Emily Meyers, the research team uncovered naturally occurring alkaloids in the defensive secretions of the Andrognathus corticarius, a species known colloquially as the Hokie millipede. The millipede, which lives under decomposing leaves and branches on the university’s Blacksburg campus, produces a chemical cocktail that not only deters predators but may influence neuroreceptors in the brain.

“These compounds are quite complex, so they’re going to take some time to synthesize in the lab,” said Meyers, who specializes in studying underexplored ecological sources for potential new drugs.

A Hidden Chemical Arsenal

The compounds, dubbed andrognathanols and andrognathines by Meyers’ team, belong to a class of complex alkaloids. They were discovered after researchers collected several millipedes from wooded areas on campus and analyzed the contents of their defensive glands using a suite of chemical tools.

The results were striking: some of these secretions had a disorienting effect on ants, one of the millipede’s presumed predators. But that’s not all, several of the compounds were found to interact with a neuroreceptor known as Sigma-1. This receptor has been linked to multiple brain disorders, including schizophrenia, depression, Lou Gehrig’s disease (ALS), and Parkinson’s disease.

In addition to warding off predators, the researchers discovered that the compounds may also serve a social function, possibly helping millipedes signal their location to family members in leaf-littered environments.

From Defense to Drug Discovery

This study, recently published in the Journal of the American Chemical Society, is not Meyers’ first foray into studying arthropod chemistry. She has been collaborating with entomologist Paul Marek, and together, they have previously suggested that the family of alkaloids found in millipede secretions could have significant therapeutic potential.

“Millipedes have been around for hundreds of millions of years. They’ve developed these intricate chemical defense systems, and we’re only beginning to understand their value,” said Meyers.

While the compounds show promise, the next hurdle is a familiar one in drug discovery: scalability. The compounds exist in trace amounts in the wild, and researchers need larger quantities for in-depth testing and potential pharmaceutical development.

The Road Ahead

The team is now exploring partnerships with laboratories that can synthesize the compounds in bulk, which would allow for further testing on their biological activity and medicinal properties. Meyers emphasized that while the research is still in its early stages, the potential applications are broad, from pain management to novel treatments for complex neurological conditions.

“Nature has always been a wellspring of inspiration for medicine,” said Meyers. “And sometimes, the most powerful solutions come from the smallest and most unexpected creatures, like a tiny millipede under a log.”

With this groundbreaking discovery, scientists are reminded once again that the natural world may hold secrets that, once unlocked, could transform human health in unimaginable ways.

Cancers are unpredictable and can be either containable or completely wreck your health. To make cancer treatments and research better, healthcare professionals use stages and characteristics, making it easier for us to categorize and identify how far along the disease is. However, recent research has been questioning our stance on this particular cancer, saying it could be worse than what we had believed.

A recent study has found that a specific type of prostate tumor, called Grade Group one (GG1), might not be as harmless as once believed. While many doctors consider these tumors to be at low risk of spreading and recommend monitoring them, the new research suggests the true risk might be higher. In fact, the study indicates that up to 30% of these cases could be more serious than doctors think, and a closer look could save lives.

Challenge with Current Practices

For years, men diagnosed with a GG1 tumor were often told to skip immediate treatment and instead undergo "active surveillance." This means they were regularly checked with blood tests and follow-up biopsies to see if the tumor was growing.

However, researchers point out a key problem: a single biopsy might miss more aggressive cancer cells located in a different part of the prostate. This could lead to a patient being undertreated, which could have serious consequences later on if the cancer grows. The authors believe that relying on just one biopsy to decide on treatment is a flawed approach.

What Are Low-Grade Prostate Tumors?

According to a 2022 review published in the Urological Research Society, the lowest grade of prostate cancer, called ISUP Grade Group 1 (GG1), grows very slowly. Because it is so harmless, some experts have suggested that we should stop calling it "cancer" at all. This has been done before for similar low-risk tumors in the bladder and thyroid.

The review summarized that even though GG1 tumors have some characteristics of cancer, their behavior is much more like a harmless, non-cancerous growth. The authors suggest that renaming GG1 prostate cancer could have several benefits:

• It could help prevent unnecessary treatments.
• It would reduce a patient's fear and stress.
• It could lower the financial costs for patients and the healthcare system.

Study's Findings

Challenging the view of previous studies, researchers sought to get a clearer understanding. To get a more accurate picture, the research team looked at data from over 300,000 men. Among those who were initially diagnosed with GG1 tumors, the team used additional factors like PSA levels and tumor size, which can be better indicators of risk.

By combining all this information, they found that a significant number of men—more than 18,000—were actually at higher risk and should have received more aggressive treatment like radiation or surgery. This data strongly suggests that as many as 30% of GG1 diagnoses might be underestimated, leaving many men without the full treatment they need.

Call for Change

The authors of the study are urging doctors to reconsider how they evaluate GG1 tumors. They emphasize that a "low grade" diagnosis from a biopsy isn't the same as a guaranteed "low risk" for the patient. They believe it's a doctor's responsibility to use all available data to accurately assess a man's individual risk. The goal is to ensure that those who need treatment get it, while still safely recommending active surveillance for the men who are truly at low risk.
