New research is stirring up conversation about a surprising connection: cat ownership and schizophrenia risk.

A large meta-analysis combining 17 studies from 11 countries suggests that people who own cats may have a slightly higher chance of developing schizophrenia-related conditions. The focus of interest is Toxoplasma gondii — a tiny parasite that can only reproduce in cats and can infect humans through contaminated food, water, or contact with cat f***s.

It’s incredibly common; an estimated 40 million Americans carry the parasite without ever realizing it. Most people never experience symptoms, but T. gondii can reach the brain and potentially influence chemicals like dopamine. That’s why scientists have long wondered whether this infection could play a role in certain mental health disorders.

The new analysis found a statistically significant link between cat ownership and schizophrenia-related outcomes. But experts stress an important point: correlation doesn’t mean causation. Most of the studies were observational, and they can’t prove that cats — or even the parasite — directly cause schizophrenia. Different studies have found different patterns too. Some suggest the timing of cat ownership (especially between ages 9 and 12) might matter, while others found no link at all with ownership but noticed a possible connection with cat bites, hinting that multiple microbes may be involved.

Overall, the science is still unfolding. The findings raise intriguing questions about how common infections may shape long-term brain health, but they’re not a reason for cat owners to panic. Instead, researchers say this is a reminder of how complex, layered, and still-evolving our understanding of mental health truly is.

Scientists may have uncovered a biological “off switch” for heart disease, diabetes, and other inflammation-driven illnesses — and it’s bringing new hope to the fight against some of the world’s biggest killers.

Researchers at the University of Texas at Arlington have zeroed in on an enzyme called IDO1, which plays a surprisingly destructive role during chronic inflammation. Normally, immune cells known as macrophages help clear cholesterol from the body. But when IDO1 becomes overactive, it throws this system off balance, stopping macrophages from processing cholesterol properly. Over time, that blockage contributes to plaque buildup, heart disease, metabolic disorders, and even certain cancers.

In lab tests, scientists managed to block IDO1, restoring healthy cholesterol processing inside these immune cells — essentially correcting the problem at its source rather than chasing symptoms after they appear.

The study also highlighted a second enzyme, nitric oxide synthase (NOS), which aggravates the damage caused by IDO1. Targeting both enzymes together could create a powerful therapeutic strategy, offering a completely new way to prevent inflammation-linked diseases before they take hold.

It’s early-stage work, but the implications are huge. If future treatments can safely switch off these harmful pathways, millions could be protected from conditions that currently require lifelong management.

🚨 A major breakthrough in the fight against HIV: an mRNA vaccine has passed a key human trial.

For the first time, scientists have shown that an mRNA-based HIV vaccine can reliably trigger the kind of antibodies long considered essential for real protection.

In a phase 1 clinical trial, more than 80% of participants who received a version of the vaccine containing a membrane-anchored HIV envelope protein developed “tier 2” neutralizing antibodies — a milestone researchers have been chasing for decades. These antibodies are especially important because they target the virus’s harder-to-reach vulnerable spots, the same regions HIV uses to slip past the immune system.

What makes this vaccine different? It uses advanced mRNA technology, similar to COVID-19 vaccines, but redesigned to present the virus’s surface proteins in a more lifelike form. That realism helps the immune system recognize and attack HIV more effectively. The shots also trained the body to build memory B cells and helper T cells, potentially laying the foundation for long-lasting immunity.

There was one notable side effect: around 6.5% of participants developed chronic hives, which scientists are now monitoring closely. Even so, the strong antibody response has given researchers the confidence to move toward larger trials that could bring us closer to a long-awaited HIV vaccine.

After decades of setbacks — from HIV’s extreme mutation rate to its ability to hide from immune defenses — this progress signals a promising new direction. If future trials succeed, the mRNA platform could finally offer a scalable, flexible path to ending one of the world’s most persistent epidemics.

Scientists have uncovered a surprising ally in stroke recovery—and it’s a molecule our own brain produces.
New research from Hungary’s HUN-REN Szeged Biological Research Centre and Semmelweis University shows that DMT (dimethyltryptamine), a naturally occurring psychedelic compound, can help the brain bounce back after a stroke by protecting two critical systems at once.

The team found that DMT helps strengthen the blood–brain barrier, the brain’s protective membrane that often becomes leaky during a stroke. It also reduces inflammation, one of the biggest drivers of long-term brain damage. In both lab-grown brain cells and animal studies, DMT noticeably reduced swelling and tissue loss by activating Sigma-1 receptors, which help cells survive stress.

Current stroke treatments mainly focus on restoring blood flow—and even then, recovery is often incomplete. These findings, published in Science Advances, suggest DMT could become an add-on therapy that boosts the brain’s natural resilience. What makes this especially promising is that early human clinical trials are already underway to test its safety and therapeutic potential.

If proven effective, this could reshape how we approach stroke care—shifting from simply minimizing damage to actively supporting the brain’s repair systems.

Scientists have uncovered a haunting mystery deep inside a cave in northern Vietnam — the 12,000-year-old remains of a man who may be the region’s earliest known murder victim.

Found at the Thung Binh 1 site in the Tràng An Landscape Complex, the man was around 35 when he died, and his bones suggested he was generally healthy. But two unusual clues changed everything.

Researchers noticed he had a rare extra rib in his neck — and right beside him lay a sharp quartz point that didn’t come from the local area. When they examined his neck bones, they discovered a fractured rib with signs of infection. The evidence points to a violent encounter: a stone-tipped spear or arrow, armed with that same foreign quartz, likely struck him in the neck. He survived the initial attack, but the resulting infection may have killed him days or weeks later.

His skull was crushed long after death, probably by shifting soil and rocks, not by violence. If researchers are right, this individual — labeled TBH1 — adds Southeast Asia to the global map of ancient homicide, joining famous prehistoric cases like the Jebel Sahaba victims in Sudan and Ötzi the Iceman in the Alps.

Finds like this don’t just reveal how people lived in the late Ice Age — they also show how far human conflict reaches back into our shared history.

Scientists are now turning the herpes virus—yes, the same one that causes cold sores—into a tool that can hunt down and destroy cancer cells.

By reprogramming HSV-1 into an oncolytic virus, researchers created modified strains like RP1 and RP2 that are engineered to infect tumors, replicate inside them, and trigger a powerful immune response. Instead of spreading disease, these altered viruses act like guided missiles.

Early clinical trials are showing real progress. Among patients with advanced, hard-to-treat cancers, roughly 25% responded to treatment. In melanoma, nearly one-third of patients saw their tumors shrink, and around 1 in 6 achieved a complete remission—something once thought impossible for many of these cases.

The approach works on two fronts.
First, the virus slips into cancer cells and multiplies until the cells burst.
Second, this viral attack sends a strong alarm signal to the immune system, teaching it to recognize and attack cancer throughout the body—even in places the virus never reached.

Most people only experience mild, flu-like symptoms, and researchers are now moving into larger Phase 3 trials. If these results hold, this could mark the beginning of a new era in precision cancer therapy, using viruses not as enemies but as allies.

Music might be more powerful than we think—especially when it comes to fighting motion sickness.

A new study from the Henan Institute of Science and Technology found that joyful, upbeat music helps people recover from nausea faster after a simulated bumpy car ride. Participants wore EEG caps while experiencing a virtual drive designed to trigger motion sickness. Afterward, each group tried a different recovery method: cheerful music, calming music, meditation, or stopping the ride early.

The standout? Happy music sped up recovery the most, reducing symptoms by about 14%, closely followed by soothing, relaxing tracks. Meditation helped too, but not as much. Surprisingly, sad music made symptoms worse, delaying recovery compared to doing nothing at all.

Researchers believe this comes down to emotional resonance: uplifting music seems to calm the body’s stress response, while sad songs intensify discomfort. EEG readings supported this—people who felt better showed richer, more complex activity in the brain’s visual-processing region.

It’s a small study, but it adds to growing evidence that what you listen to can directly influence how your body feels.

A young South African man who lost his p***s during a traditional circumcision ceremony became the world’s first recipient of a successful p***s transplant — and went on to father a child just six months later.

The groundbreaking surgery took place in December 2014 at Stellenbosch University and Tygerberg Hospital. It lasted nine hours and required meticulous microsurgical work to reconnect tiny nerves, blood vessels, and urethral structures. Remarkably, the patient regained full urinary and sexual function within only three months.

His partner’s pregnancy — confirmed six months after the operation — offered the clearest proof that the transplant had fully restored reproductive ability.

Beyond the medical milestone, this case shines a light on a deeper issue. In parts of South Africa, ritual circumcisions performed in unsafe conditions lead to severe injuries, infections, and even deaths every year. For survivors, the psychological toll can be devastating, marked by stigma, shame, and in some cases, suicidal thoughts.

Lead surgeon Dr. André van der Merwe said the goal wasn’t just physical restoration — it was giving a young man back his sense of identity and dignity. The team adapted techniques used in facial transplants, opening doors for future reconstructive procedures in regions where pe**le injuries are tragically common.

❤️ 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.

👁 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.

🚨 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.

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.
