Ozempic-style drugs could slash complication risks after heart attacks, research suggests

A popular class of weight-loss drugs may prevent life-threatening cardiac complications by opening microscopic blood vessels that often remain blocked after a heart attack, according to a study published this week in Nature Communications.

The research, led by the University of Bristol and University College London, identified a biological brain-gut-heart signaling pathway. 

This discovery appears to explain how GLP-1 drugs — which mimic glucagon-like peptide-1, a hormone that helps regulate blood sugar and appetite — protect heart tissue from a condition known as "no-reflow."

EATING OATMEAL FOR TWO DAYS HAS UNEXPECTED IMPACT ON HEART HEALTH, STUDY SUGGESTS

"In nearly half of all heart attack patients, tiny blood vessels within the heart muscle remain narrowed, even after the main artery is cleared during emergency medical treatment," Dr. Svetlana Mastitskaya, the study’s lead author and a senior lecturer at Bristol Medical School, said in a press release.

"This results in a complication known as ‘no-reflow,’ where blood is unable to reach certain parts of the heart tissue."

This lack of blood flow increases the risk of heart failure and death within a year. GLP-1 medications could prevent this, according to the researchers.

When the GLP-1 hormone is released in the gut or administered as a drug, it sends a signal to the brain, which then sends a signal to the heart that switches on special potassium channels in tiny cells called pericytes.

When these channels open, the pericytes relax, which allows the small blood vessels (capillaries) to widen and improve blood flow to the heart muscle, the researchers noted.

The new study used animal models and cellular imaging to track how GLP-1 interacts with heart tissue. When the researchers removed the potassium channels, the drugs no longer protected the heart — confirming they play a key role.

The findings suggest that existing GLP-1 medications, already used for type 2 diabetes and obesity, could be repurposed as emergency treatments during or immediately after a heart attack to reduce tissue damage.

The researchers noted several limitations, including that the study relied on animal models.

Clinical trials are necessary to determine whether the brain-gut-heart pathway operates with the same timing and efficacy in humans.

Additionally, while the study highlights the drug's immediate benefits during a heart attack, it does not establish whether long-term use of the medication provides a pre-existing level of protection.

Do collagen supplements really improve skin? Major review reveals the truth

Collagen supplements have exploded in popularity, touted as everything from an anti-aging miracle to a muscle recovery booster.

But a sweeping new review conducted by U.K. researchers suggests that while collagen may help improve skin elasticity and ease arthritis pain, it does little for athletic performance or wrinkle reduction.

Researchers from Anglia Ruskin University analyzed 16 systematic reviews and 113 randomized controlled trials involving nearly 8,000 participants worldwide, which they say is the most extensive evaluation of collagen’s health effects to date. 

COSMETIC FILLERS CAN CAUSE DEADLY COMPLICATION, EXPERTS WARN — BUT NEW TECH EXPOSES IT

The review found consistent evidence that collagen supplementation improves skin elasticity and hydration over time and provides significant relief from osteoarthritis-related joint pain and stiffness, according to findings published in Aesthetic Surgery Journal Open Forum. 

The researchers, however, did not find meaningful improvements in post-exercise muscle recovery, soreness or tendon mechanical properties (strength, springiness and stretch resistance).

"Collagen is not a cure-all, but it does have credible benefits when used consistently over time, particularly for skin and osteoarthritis," co-author Lee Smith, professor of public health at Anglia Ruskin University, said in a statement.

EXPERIMENTAL SERUM SHOWS PROMISE IN REVERSING BALDNESS WITHIN 20 DAYS

"Our findings show clear benefits in key areas of healthy aging, while also dispelling some of the myths surrounding its use," Smith added.

Collagen, the most abundant protein in the body, supports skin, bones, tendons, cartilage and connective tissue, according to experts. Natural collagen production begins to drop in early adulthood and declines more sharply with age.

The review found that long-term collagen supplementation was linked to improved skin firmness and hydration, but did not help skin roughness — a proxy for visible wrinkles. 

Benefits appear to accumulate gradually, suggesting that collagen should not be viewed as an "anti-wrinkle 'quick fix,' but as a foundational dermal support for individuals seeking holistic skin maintenance," the researchers said.

"If we define anti-aging as a product or technique designed to prevent the appearance of getting older, then I believe our findings do support this claim for some parameters," Smith told the BBC. "For example, an improvement in skin tone and moisture is associated with a more youthful-looking appearance."

Collagen supplementation was linked to reduced pain and stiffness in people with osteoarthritis, with stronger benefits seen over longer periods of use, and showed modest improvements in muscle mass and tendon structure that may support healthy aging. 

However, it did not show meaningful results when used as a fast-acting sports performance supplement, and evidence for benefits related to cholesterol, blood sugar, blood pressure and oral health was mixed or inconclusive.

Dr. Daniel Ghiyam, a California-based physician and longevity specialist, said the findings align with what he sees in clinical practice.

"Collagen is a targeted support tool, not a foundation of health or performance," Ghiyam, who was not involved in the study, told Fox News Digital. "When marketed that way, it makes sense. When marketed as a cure-all, it doesn’t hold up to the data."

The authors noted that while many previous collagen studies have received financial support from the supplement industry, the current review did not receive industry funding.

The team called for more high-quality clinical trials examining long-term outcomes, optimal dosages, and differences between collagen sources, such as marine, bovine and plant-based alternatives. 

Among its limitations, the review could not determine whether certain forms of collagen work better than others or what the optimal regimen should be.

While the review included randomized controlled trials, the quality of the studies varied, with newer research generally showing stronger results.

Experts say more data and studies are needed to build on the findings. They also noted that diet plays a crucial role in skin health.

Dr. Erum Ilyas, a Pennsylvania-based dermatologist and chair of dermatology at Drexel University College of Medicine, noted that the review analyzed previously published meta-analyses rather than generating new primary data.

"At this time, I have not seen sufficiently strong independent evidence to routinely recommend collagen supplements to my patients," Ilyas, who was not involved in the review, told Fox News Digital.

"Although some studies show modest improvements in markers such as hydration and elasticity, there remains limited independent, biopsy-confirmed evidence demonstrating sustained increases in dermal collagen content," she added.

Fox News Digital has reached out to the researchers for comment.

Origin of deadly cancer affecting young adults revealed in alarming report

As colorectal cancer (CRC) is now the leading cause of cancer death in adults under 50, a new report reveals some surprising shifts in the incidence of the disease.

Although rates of CRC have been declining among seniors, those 65 and under are facing a rise in diagnoses, according to a report titled Colorectal Cancer Statistics, 2026, from the American Cancer Society.

Adults 65 and younger comprise nearly half (45%) of all new colorectal cancer cases — a significant increase from 27% in 1995, states the report, which was published in CA: A Cancer Journal for Clinicians.

DISEASE RISING 3% ANNUALLY AMONG 20-49 AGE GROUP, WITH RECTAL CANCER CASES INCREASING TO ONE-THIRD OF ALL DIAGNOSES

The disease is rising fastest among adults 20 to 49 years old, at a rate of 3% per year.

Among adults 50 and under, 75% of colorectal cancers are diagnosed at an advanced stage. Half of the diagnoses in that age range are made between the ages of 45 and 49. Although that age group is eligible to receive routine screenings, just 37% do so.

The report also revealed that rectal cancer is on the rise, now accounting for about one-third (32%) of all CRC cases — an increase from 27% in the mid-2000s.

"After decades of progress, the risk of dying from colorectal cancer is climbing in younger generations of men and women, confirming a real uptick in disease because of something we’re doing or some other exposure," said Rebecca Siegel, senior scientific director, surveillance research at the American Cancer Society and lead author of the report, in a press release.

"We need to redouble research efforts to understand the cause, but also circumvent deaths through earlier detection by educating clinicians and the general public about symptoms and increasing screening in people 45-54 years."

It is projected that 158,850 new cases of colorectal cancer will be diagnosed this year, and that the disease will cause 55,230 deaths, per the report.

More than half of CRC cases can be linked to high-risk behaviors, the researchers said. Those include lack of nutrition, high alcohol consumption, smoking, lack of exercise and obesity.

"These findings further underscore that colorectal cancer is worsening among younger generations and highlight the immediate need for eligible adults to begin screening at the recommended age of 45," said Dr. William Dahut, chief scientific officer at the American Cancer Society.

"The report also shines a light on the crucial importance of continued funding for research to help discover new therapies to treat the disease and advance patient care."

When the disease is caught at a local (early) stage, the five-year survival rate is 95%, the report stated.

Aging process could accelerate due to 'forever chemicals' exposure, study finds

A new study suggests that middle-aged men may be more vulnerable to faster biological aging, potentially linked to exposure to "forever chemicals."

The research, published in the journal Frontiers in Aging, examined how perfluoroalkyl and polyfluoroalkyl substances, more commonly known as PFAS, could impact aging at the cellular level.

PFAS are synthetic chemicals commonly used in nonstick cookware, food packaging, water-resistant fabrics and other consumer products, the study noted. 

NIGHTLY BATHROOM HABIT WAS MISSED SIGN OF COMMON MEN'S CANCER: ‘I DIDN’T KNOW’

Their chemical structure makes them highly resistant to breaking down, allowing them to accumulate in water, soil and the human body.

Chinese researchers analyzed blood samples from 326 adults enrolled in the U.S. National Health and Nutrition Examination Survey between 1999 and 2000.

The researchers measured levels of 11 PFAS compounds in participants’ blood and used DNA-based "epigenetic clocks" — tools that analyze chemical changes to DNA to estimate biological age — to determine how quickly their bodies were aging at the cellular level, the study stated.

Two compounds, perfluorononanoic acid (PFNA) and perfluorooctanesulfonamide (PFOSA), were detected in 95% of participants.

Higher concentrations of those chemicals were associated with faster biological aging in men of certain age groups, but not in women.

The compounds most strongly linked to accelerated aging were not the PFAS chemicals that typically receive the most public attention, the researchers noted.

"The associations were strongest in adults aged 50 to 64, particularly in men," Dr. Xiangwei Li, professor at Shanghai Jiao Tong University School of Medicine and the study’s corresponding author, told Fox News Digital. 

"While this does not establish that PFAS cause aging, it suggests that these widely present ‘forever chemicals’ may be linked to molecular changes related to long-term health and aging."

Midlife may represent a more sensitive biological period, when the body becomes more vulnerable to age-related stressors, according to the researchers.

Lifestyle factors, such as smoking, may influence biological aging markers, potentially increasing vulnerability to environmental pollutants.

While Li said "people should not panic," she does recommend looking for reasonable ways to reduce exposure. 

That might mean checking local drinking water reports, using certified water filters designed to reduce PFAS, and limiting the use of stain- or grease-resistant products when alternatives are available.

Meaningful reductions in PFAS exposure will likely depend on broader regulatory action and environmental cleanup efforts, Li added.

The researchers outlined several important limitations of the research, including that the findings show an association, but do not prove that PFAS directly causes accelerated aging.

"The study is cross-sectional, meaning exposure and aging markers were measured at the same time, so we cannot determine causality," Li told Fox News Digital.

The study was also relatively small, limited to 326 adults age 50 or older, which means the findings may not apply to younger people or broader populations.

Researchers measured PFAS levels using data collected between 1999 and 2000, and today's exposure patterns may differ.

Li added that while PFAS is known to persist in the environment and the body, these results should be validated through larger, more recent studies that follow participants over time.

Alzheimer’s prevention breakthrough found in decades-old seizure drug

A drug that has long been used to treat seizures has shown promise as a potential means of Alzheimer’s prevention, a new study suggests.

The anti-seizure medication, levetiracetam, was first approved by the FDA in November 1999 under the brand name Keppra as a therapy for partial-onset seizures in adults. The approval has since expanded to include children and other types of seizures.

Northwestern University researchers recently found that levetiracetam prevented the formation of toxic amyloid beta peptides, which are small protein fragments in the brain that are commonly seen in Alzheimer’s patients.

ALZHEIMER’S DECLINE COULD SLOW DRAMATICALLY WITH ONE SIMPLE DAILY HABIT, STUDY FINDS

The medication was found to prevent the formation of amyloid-beta 42 in both animal models and cultured human neurons, according to the study findings, which were published in Science Translational Medicine.

The effect was also seen in post-mortem human brain tissue obtained from individuals with Down syndrome, who are at high risk for Alzheimer’s disease.

"While many of the Alzheimer’s drugs currently on the market, such as lecanemab and donanemab, are approved to clear existing amyloid plaques, we’ve identified this mechanism that prevents the production of the amyloid‑beta 42 peptides and amyloid plaques," said corresponding author Jeffrey Savas, associate professor of behavioral neurology at Northwestern University Feinberg School of Medicine, in a press release. 

"Our new results uncovered new biology while also opening doors for new drug targets."

HIDDEN BRAIN CONDITION MAY QUADRUPLE DEMENTIA RISK IN OLDER ADULTS, STUDY SUGGESTS

The brain is better able to avoid the pathway that produces toxic amyloid‑beta 42 proteins in younger years, but the aging process gradually weakens that ability, Savas noted. 

"This is not a statement of disease; this is just a part of aging. But in brains developing Alzheimer’s, too many neurons go astray, and that’s when you get amyloid-beta 42 production," he said. 

That then leads to tau ("tangles") — abnormal clumps of protein inside brain neurons — which can kill brain cells, trigger neuroinflammation and lead to dementia.

In order for levetiracetam to function as an Alzheimer’s blocker, high-risk patients would have to start taking it "very, very early," Savas said — up to 20 years before elevated amyloid-beta 42 levels would be detected.

"You couldn’t take this when you already have dementia, because the brain has already undergone a number of irreversible changes and a lot of cell death," the researcher noted.

The researchers also did a deep dive into previous human clinical data to determine whether Alzheimer’s patients who were taking the anti-seizure drug had slower cognitive decline. They reported that the patients in that category had a "significant delay" in the span from cognitive decline to death compared to those not taking the drug.

"Although the magnitude of change was small (on the scale of a few years), this analysis supports the positive effect of levetiracetam to slow the progression of Alzheimer’s pathology," Savas said.

Looking ahead, the research team aims to find people who have genetic forms of Alzheimer’s to participate in testing, Savas said.

The study had several limitations, including that it relied on animal models and cultured cells, with no human trials conducted.

Because the study was observational in nature, it can’t prove that the medication caused the prevention of the toxic brain proteins, the researchers acknowledged.

Savas noted that levetiracetam "is not perfect," cautioning that it breaks down in the body very quickly.

The team is currently working to create a "better version" that would last longer in the body and "better target the mechanism that prevents the production of the plaques."

The medication’s common documented side effects include drowsiness, weakness, dizziness, irritability, headache, loss of appetite and nasal congestion.

It has also been linked to potential mood and behavior changes, including anxiety, depression, agitation and aggression, according to the prescribing information. In rare cases, it could lead to severe allergic reactions, skin reactions, blood disorders and suicidal ideation.

Seniors over 80 who eat specific diet may be less likely to reach 100 years old

Older adults who avoid meat in their golden years may be less likely to reach age 100 than their meat-eating counterparts, new research suggests.

Researchers tracked more than 5,000 adults aged 80 or older who were enrolled in the Chinese Longitudinal Healthy Longevity Survey.

Between 1998 and 2018, data showed that those who did not eat meat were less likely to reach their 100th birthday than those who consumed animal products regularly.

SCIENTISTS REVEAL THE ONE PRACTICE THAT COULD PREVENT DEMENTIA AS YOU AGE

The findings seem to contradict previous studies that have linked vegetarianism and plant-based diets to lower risks of heart disease, stroke, diabetes and obesity.

Most evidence supporting the benefits of plant-based diets comes from studies tracking younger populations, the researchers noted. 

The study, published in The American Journal of Clinical Nutrition, points to losses in muscle mass and bone density with age, shifts that can increase the risk of malnutrition and frailty in the "oldest old."

As people enter their 80s and 90s, the nutritional priority often shifts from preventing long-term chronic diseases to maintaining day-to-day physical function, experts say.

HOW MUCH RED MEAT IS TOO MUCH? EXPERTS WEIGH IN ON FOOD PYRAMID UPDATES

"The headline ‘vegetarians over 80 less likely to reach 100’ sounds surprising, because it contrasts with decades of data linking plant‑forward diets to lower chronic disease risk earlier in life," Erin Palinski-Wade, a New Jersey-based registered dietitian, told Fox News Digital. 

"However, once you see that this research is limited to adults over the age of 80 who are also underweight — and that this link disappears with the consumption of eggs, dairy and fish — the results are less surprising."

In those over 80, restricting animal proteins may be less likely to promote longevity, according to Palinski-Wade, who was not involved in the study.

Eliminating all animal protein — particularly in a population that may already experience diminished hunger cues — can make it more difficult to meet adequate protein needs, potentially increasing the risk of nutrient deficiencies, the nutritionist said.

ALZHEIMER'S SYMPTOMS COULD BE PREDICTED YEARS IN ADVANCE THROUGH ONE SIMPLE TEST

In addition to a higher tendency to be underweight, older populations also face a greater risk of bone fractures due to lower calcium and protein intake.

The lower rate of vegetarians reaching 100 was only observed in participants identified as underweight, the researchers noted. No such association was found in people who maintained a healthy weight.

Because being underweight is already linked to greater frailty and mortality risk, the researchers noted that body weight may partly explain the findings, making it difficult to determine whether diet itself played a direct role.

Additionally, the shortened lifespans were not found in people who continued to eat non-meat animal products, such as fish, dairy and eggs. 

Older adults with these more flexible diets were just as likely to live to 100 as those eating meat, as these foods may provide the nutrients necessary for maintaining muscle and bone health, the researchers noted.

"This is an observational study, so it can only show associations, and does not prove that avoiding meat directly reduces the odds of reaching 100," Palinski-Wade added.

The researchers suggested that including small amounts of animal-sourced foods could help older seniors maintain essential nutrients and avoid the muscle loss often seen in those who stick strictly to plants.

Palinski-Wade offered some guidance for those looking to optimize nutrition later in life.

"For adults in their 80s and beyond, especially anyone losing weight or muscle, the priority should be maintaining a healthy weight and meeting protein and micronutrient needs — even if that means adding or increasing fish, eggs, dairy or well‑planned, fortified plant proteins and supplements."

TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZ

Strict vegan or very low‑protein patterns at that age should be carefully monitored by a dietitian or clinician, with attention to B12, vitamin D, calcium and total protein, according to Palinski-Wade.

"Younger and healthier adults can still confidently use plant‑forward or vegetarian patterns to lower long‑term chronic disease risk," she added.

Punch the monkey, viral star, experiences dramatic breakthrough among zoo mates

In a dramatic turn of events that's captured the attention of animal lovers worldwide, Punch — the young macaque at a zoo in Japan famous for his inseparable bond with a stuffed orangutan toy — has reached a major milestone in his journey toward social integration.

On Thursday, visitors and staff at the Ichikawa Zoological and Botanical Garden witnessed a breakthrough: Punch was seen cuddling with and hitching a ride on the back of a fellow macaque.

Punch’s story began with hardship. He was abandoned by his mother shortly after his birth in July 2025 — and to ensure his survival, zookeepers stepped in to hand-rear the primate.

ORPHANED BABY MONKEY FINDS COMFORT IN STUFFED ANIMAL AFTER BEING ABANDONED BY MOTHER AT BIRTH

On Jan. 19, 2026, the zoo officially began the process of reintegrating Punch into the "monkey mountain" enclosure.

The transition was initially fraught with tension. 

As a hand-reared infant, Punch was bullied and ignored by the established group of monkeys.

He was often seen huddled alone with his orange plush companion while the rest of the troop interacted.

BABY MONKEY CARRIES FAITHFUL STUFFED COMPANION EVERYWHERE HE GOES, DRAWING CROWDS AT ZOO

In an official statement released Feb. 27, the Ichikawa Zoological and Botanical Garden detailed the meticulous care behind this process.

"From an animal welfare perspective, our primary goal is to reintegrate Punch with the troop," the zoo said.

The strategy involved nursing Punch within the enclosure, so the troop could recognize him as one of their own, and pairing him with a gentle young female macaque prior to his full release to build his confidence.

The latest footage, captured by X user @tate_gf, suggested the zoo's patience is paying off. 

The video shows Punch seeking physical contact not from his toy, but from another monkey — eventually climbing onto its back for a vital social behavior for young macaques: the "piggyback ride."

While Punch still carries his stuffed toy for comfort during moments of perceived danger, the zoo remains optimistic about his progress.

The organization cited the successful 2009 case of Otome, another hand-reared macaque who eventually outgrew her stuffed toy, successfully integrated — and went on to raise four offspring of her own.

The zoo has had crowds coming to see Punch, with hundreds of people lining up to get inside to see the young star, according to reports.
