Scientists have just taken a major leap in medical imaging by building the first-ever perovskite-based camera for nuclear imaging—and it could transform how doctors diagnose diseases deep inside the body.

A team from Northwestern University and Soochow University has created a gamma-ray detector made from perovskite crystals, a material best known for powering next-generation solar cells. Now, it’s stepping into the medical world with impressive results.

SPECT scans, commonly used to detect heart disease and cancer, work by capturing gamma rays released by tiny radioactive tracers. The problem? Current detectors are either powerful but extremely expensive and fragile, or cheaper but produce lower-quality images.

The new perovskite detector bridges that gap. It delivers sharper, cleaner images, picks up extremely faint gamma-ray signals, and can even resolve tiny details separated by just a few millimeters. That means faster scans, lower radiation exposure, and potentially more accurate diagnoses.

What makes this breakthrough even more promising is the cost. Perovskite materials are simpler to grow and manufacture, meaning hospitals could eventually offer high-quality nuclear imaging without the high price tag. A Northwestern spinoff, Actinia Inc., is now working to bring this detector to clinics worldwide, opening the door to earlier detection of serious illnesses in places that currently lack advanced imaging technology.

A clearer, safer, and more affordable look inside the human body may be closer than we think.

At first glance, it looks like a masked human staring straight at you.
But look closer—those “eyes,” that “mouth,” and that eerie expression all belong to a beetle.

This stunning close-up captures the white-striped longhorn beetle (Batocera lineolata) in remarkable detail, photographed by macro artist Dara Ojo in Jiaxing, China. The water droplets sitting perfectly on its face-like features create an uncanny illusion that fooled thousands.

Ojo, a Nigerian photographer who fell in love with insect macro work during the pandemic, regularly shares these surreal moments on Instagram at . Even he didn’t expect this particular image to blow up the way it did.

After landing on Reddit’s “Nature Is F***ing Lit” community, the photo exploded—earning over 43,000 upvotes and sparking a flood of comments. Some joked it looked like a new Slipknot band member, others swore it was a human wearing a bug mask. The internet loves a good visual illusion, and this one delivered.

But in reality, it’s just nature showing off again—100% beetle, 100% real, and absolutely wild.

The clouds created by atomic bombs are exceptionally large.

Here's a handy visual guide to just how big they are.

And this clous doesn't even represent the world's largest bomb — Tsar Bomba. The explosion's mushroom cloud rose to a height of 67 km (42 mi).

Meanwhile, Mount Everest is just 8.9 km (5.5 miles) tall.

Body fat isn’t just “extra weight” — it’s one of the most active and intelligent tissues in your body.

Known medically as adipose tissue, this soft connective tissue comes in two main forms: white fat, which stores energy and cushions vital organs, and brown fat, which burns energy to generate heat, especially in infants and during cold exposure. You’ll find adipose tissue under the skin, around your organs, between your muscles, and even embedded in your bones.

What makes it remarkable is that it behaves like an endocrine organ. Your fat actually communicates with your brain and other organs by releasing hormones such as leptin, adiponectin, and resistin. Through these signals, it helps regulate hunger, metabolism, immune responses, inflammation, and even how your body handles glucose.

But balance is everything.
When fat cells become overloaded—as in obesity—they swell and start producing inflammatory molecules. This chronic inflammation disrupts metabolism, raises the risk of insulin resistance, and contributes to heart disease. On the other hand, having too little fat also harms the body, limiting its ability to store essential lipids, maintain hormones, and regulate temperature.

Understanding adipose tissue isn’t just a scientific curiosity—it’s a key part of understanding long-term health. Maintaining healthy fat levels through nourishing food, movement, sleep, and stress control supports one of your body’s most underrated organs.

🚨 New research shows COVID-19 may age your blood vessels by up to 5 years — and women are hit the hardest.

A major international study has uncovered something deeply concerning: even a mild COVID-19 infection can make your arteries behave as if they’re several years older. And for women, the impact appears even more pronounced.

Scientists analyzed over 2,300 people from 16 countries and discovered a clear rise in arterial stiffness, a key early warning sign for heart attacks and strokes. They measured this using pulse wave velocity (PWV)—a test that shows how fast blood moves through arteries. Faster waves mean stiffer vessels, and stiffer vessels mean higher cardiovascular risk.

What makes this especially worrying is how COVID affects the lining of blood vessels. The virus binds to ACE2 receptors, triggering inflammation that accelerates the ageing of vascular tissue. Women with long COVID or those who had been hospitalized showed the greatest changes, sometimes equivalent to five years of vascular ageing.

There is some good news: people who were vaccinated had noticeably healthier readings, and many participants showed gradual improvement as time passed. Still, the changes were significant enough that researchers are urging doctors to monitor heart and vascular health more closely in post-COVID patients, particularly older women.

This study adds to a growing body of evidence showing that COVID-19 doesn’t just affect the lungs — it can leave long-lasting marks on the cardiovascular system, too.

👁 Doctors just removed a spinal tumor through the eye socket—a medical first that’s rewriting what’s possible in neurosurgery.

In a groundbreaking procedure at the University of Maryland Medical Center, surgeons successfully reached and removed a spinal tumor by entering through a patient’s eye socket—a route never before used to access the spine.

The patient, 19-year-old Karla Flores, had a dangerous chordoma wrapped tightly around her upper cervical spine, sitting close to nerves and blood vessels that control essential movement and breathing. Operating through the neck or back would have carried major risks, so neurosurgeon Dr. Mohamed A.M. Labib and his team took an entirely new path.

Using a refined transorbital technique—normally used for certain brain tumors—they created a narrow corridor through the eye socket and navigated directly to the tumor. This approach allowed them to remove it with stunning precision, avoid major structural damage, and leave no visible scars. The method was perfected through extensive cadaver research and teamwork across multiple specialties.

After the surgery, Flores received proton therapy and a stabilizing spinal fusion. Today, she is recovering cancer-free—and her case is opening the door to a new era of minimally invasive spine surgery.

This milestone shows how innovation, careful planning, and bold thinking can completely reshape complex medical treatment.

❤️ 99% of heart attacks, strokes, and heart failure cases can be traced back to preventable risk factors.
And the most important changes start long before symptoms ever appear.

A major new study published in The Journal of the American College of Cardiology has revealed something striking: almost everyone who experiences a serious cardiovascular event had at least one warning sign that could have been managed earlier.

Researchers analyzed health data from more than 9 million people in South Korea and nearly 7,000 individuals in the U.S., focusing on four key risk factors we often ignore:

• High blood pressure

• High cholesterol

• Elevated fasting glucose

• To***co use

Out of all these, high blood pressure emerged as the biggest culprit—present in over 93% of Americans and 95% of South Koreans before their heart attack, stroke, or heart-failure episode.

These findings challenge the belief that heart disease “just happens.” In reality, nearly every case is preceded by changes in the body that are both detectable and treatable.

Even among women under 60, more than 95% had at least one of these risk factors. According to lead author Dr. Philip Greenland, routine screening and early action—even when numbers are just slightly above normal—could dramatically reduce the global burden of cardiovascular disease.

The message is simple but powerful:
If we take blood pressure, cholesterol, blood sugar, and smoking seriously today, we can prevent the vast majority of heart-related deaths tomorrow.

🍬 A low-sugar start in life could change your child’s entire future.

A major new study has found that keeping sugar intake extremely low during the first years of life—including during pregnancy—can dramatically reduce the risk of chronic diseases later on. Researchers discovered that children who experienced sugar rationing in their earliest 1,000 days had up to a 35% lower risk of developing Type 2 diabetes and a 20% lower risk of high blood pressure as adults.

This insight comes from a unique moment in history. Scientists analyzed UK Biobank data from adults born just before and after the end of Britain’s wartime sugar rationing in 1953. During the rationing period, infants and toddlers consumed almost no added sugar—levels far below what most children eat today. That brief nutritional window created a “natural experiment,” allowing researchers to see how early-life diets shape lifelong health.

What’s even more surprising: the benefits began in the womb. Babies whose mothers lived under sugar rationing during pregnancy also showed reduced disease risk decades later.

As sugar consumption surged in the post-war years, the long-term health advantages faded—highlighting how powerful, and how fragile, the effect of early nutrition can be. The findings strengthen calls for stricter sugar guidelines for infants and toddlers, emphasizing that what happens in the first thousand days truly echoes across a lifetime.

🧠 Scientists may have just taken a major step toward reversing Alzheimer’s — using nanoparticles that heal the brain’s own defenses.
A new study from researchers in Spain and China has shown that tiny, engineered nanoparticles can clear toxic Alzheimer’s plaque in mice within just one hour — and even reverse months of memory impairment.
Instead of attacking amyloid beta directly, the treatment works by repairing the blood–brain barrier (BBB), the brain’s critical filtration and protection system that begins to break down long before symptoms appear. These nanoparticles act like a “supramolecular drug,” restoring the function of LRP1, a key protein responsible for clearing waste from the brain.
With the BBB working again, plaque levels dropped by up to 60%, inflammation eased, and blood flow improved. Even mice with advanced cognitive decline began behaving normally after six months — an outcome rarely seen in Alzheimer’s research.
While this breakthrough is still in animal studies, it opens an entirely new direction for treatment: instead of just removing damage, help the brain repair its own cleanup system. Scientists believe this approach could reshape how we diagnose, prevent, and treat neurodegenerative diseases in the future.

🦷 Your wisdom teeth might hold the key to future life-saving treatments.

Most of us think of wisdom teeth as nothing more than a painful inconvenience — something to remove and forget. But researchers now say those teeth we throw away could one day help repair the very tissues that keep us alive.

Inside every wisdom tooth lies a pocket of mesenchymal stem cells, remarkably flexible cells capable of turning into bone, muscle, cartilage, and even nerve tissue. That means a simple extraction — something millions undergo every year — could quietly provide a personal reservoir of repair cells with enormous therapeutic potential.

Because these stem cells are collected from the tooth’s pulp during a procedure you’re already having, there’s no extra pain, no additional surgery, and no risk. Companies like Stem Save, working with dental clinics such as Innovative Implant and Oral Surgery, now offer cryopreservation services so patients can store these cells for decades. Think of it as a biological safety net — a resource you hope you never need, but may be grateful to have.

Early research is already showing promise. Dental stem cells have been investigated for treating arthritis, diabetes, heart damage, spinal injuries, corneal repair, and even neurodegenerative conditions like Alzheimer’s and Parkinson’s. While clinical use is still developing, the potential is significant: what was once medical waste may soon play a leading role in regenerative medicine.

🚫 New research warns that both sugary and diet sodas may seriously harm your liver.

A major new analysis has added to growing concerns about soft drinks—revealing that neither regular nor diet sodas are as harmless as many believe. The study, based on data from more than 103,000 adults in the UK Biobank, found that drinking just a little over one can (330 ml) of these beverages a day was linked to a 50–60% higher risk of developing metabolic dysfunction–associated steatotic liver disease (MASLD), a form of fatty liver disease not caused by alcohol.

One of the most surprising findings was that diet sodas showed an even stronger link to liver-related death, with risks climbing as consumption increased. While the study hasn’t yet been fully peer-reviewed, it was presented at UEG Week 2025—one of Europe’s leading gastroenterology conferences—making the results hard to ignore.

Researchers also highlighted a simple but powerful shift: swapping even one daily soda for water lowered the risk of developing liver disease, reinforcing how small changes in everyday habits can protect long-term health.

The findings challenge the long-standing belief that diet drinks are the “safer” choice and suggest that both types of sodas may play a role in damaging liver health over time. More research is needed to understand the exact mechanisms, but this study offers yet another reason to rethink what we drink.

Diet soda isn’t the harmless “zero-calorie” swap many people think it is.
A major long-term study following more than 36,000 adults for nearly 14 years found something surprising — drinking just one can of artificially sweetened soft drink a day was linked to a more than 35% higher risk of developing type 2 diabetes. And shockingly, that risk was even higher than from regular sugary sodas.
While sugar-sweetened drinks raised diabetes risk by about 23%, diet drinks went beyond that. Even after researchers adjusted for weight, age, lifestyle habits, and body fat, the association stayed strong. This means the danger doesn’t seem to come from weight gain alone.
Why would a “sugar-free” drink have this effect? Scientists think artificial sweeteners may interfere with how our body handles glucose. These sweeteners — like aspartame, sucralose, and saccharin — can disrupt gut bacteria, confuse insulin signals, or alter metabolic pathways in ways that push the body toward glucose intolerance. Earlier research has already shown they can change the gut microbiome or trigger insulin spikes, even without real sugar.
The takeaway is simple: switching from regular soda to diet soda isn’t necessarily a safer choice for your metabolic health. The body still reacts — just in ways we’re only beginning to understand.
