A New Study Says You Can Delay Death—but Not the Speed of Aging
Here's what you'll learn when you read this story: With incredible changes in our species' lifespan over the past century, some aging experts have pondered whether the biology of aging—or senescence—is changing. To explore this question, a new study re-examines a popular theory that the rate of aging hasn't changed—it's just been delayed by about a decade. By analyzing mortality data from Italy, Denmark, France, and Sweden, and refining it to reflect age-related deaths, the researchers show that any deviation among populations is likely a symptom of 'historical shocks' rather than biological changes. To say that 'anti-aging' is an obsession in the U.S. would be a bit of an understatement. In 2024, for example, experts valued the anti-aging industry at around $52 billion, with every expectation for it to grow beyond $100 billion by the end of the decade. The promise of these products to stop—or, at the very least, curtail—aging's most deleterious effects is a convincing one. After all, haven't we proven over the past decade that improved habits and living conditions can shoot a population's life expectancy into the atmosphere? However, this picture is much more complicated for scientists studying aging, which is also known as 'senescence.' It can be argued that life expectancy—mostly due to improved nutrition and medical advancements (especially the lowering of the infant mortality rate)—has improved across generations, and it's now expected that the centenarian population in the U.S. will quadruple over the next 30 years. But one question in decades of research in human aging remains unanswered: Could the rate of human senescence somehow be changing across generations? It's a question that's been pondered for quite some time. The foundations of this mortality-related research date back to the early 19th century, when mathematician Benjamin Gompertz first devised mortality rates. His work showed that, initially, rates started very low, but increased the same percentage year after year. However, the rates continue to grow as we age, sort of like compounding interest in a 401(k). It starts off slow and first, but then it really takes off. In a new study uploaded to the preprint server aXiv by Silvio Patricio, a research assistant at the Interdisciplinary Centre on Population Dynamics at the University of Southern Denmark analyzed this question by revisiting a theory first postulated by James W. Vaupel in 2010. In his study, Vaupel discovered that the rate of human senescence—the one largely calculated by Gompertz in 1825— hadn't changed among generations, but that the process of aging had been delayed by a decade. Vaupel built this hypothesis from a variety of research dating back to 1994, and found that the slope of mortality largely remained unaltered. However, other studies challenged this theory by finding small-but-persistent variations among aging rates. 'These patterns raise a deeper question: are we seeing real biological change in how humans age—or are we seeing something else?,' Patricio wrote. 'One possibility is that what looks like a change in [the rate of aging] is not biological at all, but historical. Period events—such as World War I, the 1918 flu, or World War II—affect many cohorts at once, just at different ages […]. If such events have lasting consequences, they could subtly distort cohort-level mortality patterns.' Patricio sets out to settle the matter once and for all. Using a mixture model, the researcher separated senescent mortality (that is, age-related deaths) from general cohort mortality data from France, Denmark, Italy, and Sweden (he also refined the data to lessen the influence of early-life mortality). After developing cohort-specific estimates of the Gompertz slope, Patricio found that aging wasn't perfectly constant across cohorts, and that this was likely due to a drift caused by population shocks that cohorts carry as 'echoes' of these past events—even if they occurred outside their own lifespan. 'Once we filter out non-senescent mortality and account for the accumulation of shared period effects, [the rate of aging] becomes strikingly consistent,' Patricio wrote. 'There is no meaningful trend, and no evidence that the biology of aging is shifting across cohorts. The variation that remains is not biological drift, but the footprint of history—the cumulative result of shocks experienced in calendar time.' So, if the rate of aging is truly immutable, is the anti-aging industry basically one big snake oil salesman? Well, yes and no. While the rate of aging is remarkably constant across generations and populations, eating well, exercising, and getting enough sleep will still do wonders for your longevity and make sure that the compounding interest of your mortality doesn't catch up with you prematurely. The rate at which we gray may be an immutable fact of our biology, but that doesn't mean we can't do so with some measure of grace.

Mom's Hormone Levels While Pregnant Linked to Kids' Physical Activity
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. A mother's hormones during pregnancy can negatively affect her child years later, a new study has cautioned. Boys whose mothers had polycystic ovarian syndrome (PCOS) or elevated testosterone levels during the third trimester of pregnancy appear less physically active by age seven. The effect wasn't seen in girls, but girls exposed to higher testosterone levels in the womb were found to have lower muscle strength at age seven. The study, led by researchers at Odense University Hospital and the University of Southern Denmark, analyzed data from 695 pregnant women and their children. Using an accelerometer—a device that tracks changes in movement—the team measured the physical activity of the seven-year-olds and discovered boys born to mothers with PCOS were less active, particularly on weekends, compared to their peers.

Dima Berlin Additionally, this reduced activity wasn't due to factors like birth weight or the mother's pre-pregnancy body mass index (BMI). Instead, it seems directly tied to higher maternal testosterone levels—a hormone that typically spikes during pregnancy and is even higher in women with PCOS. Camilla Viola Palm, the study's lead author, explained that while previous research often relied on questionnaires to gauge child activity, this study's use of objective movement tracking makes its findings especially compelling. "Maternal pre-pregnancy health conditions, like PCOS, may transgenerationally affect the physical activity of boys," she said. Palm also warned that a drop in physical activity, especially on weekends when children have more free time, could set the stage for future obesity and cardiovascular disease (CVD) in these boys. For girls, higher testosterone exposure during pregnancy didn't impact their activity levels but did result in lower muscle strength, which may also have long-term health consequences. This is the latest in a series of findings by the team, which previously showed that boys exposed to higher prenatal testosterone had more body fat by age seven and lower grip strength by age five. The researchers are now planning to follow these children into adolescence to see if the effects persist, potentially impacting obesity, blood pressure and type 2 diabetes risk. "There is only little data on boys regarding PCOS-related metabolic and CVD risk, as PCOS is a female condition by definition," Palm said. The research also suggests the effects of PCOS and the hormone imbalances it causes, may extend to the next generation. The research was presented at the first Joint Congress between the European Society of Pediatric Endocrinology and the European Society of Endocrinology.

The 3 conditions that are more likely to kill MEN revealed – as experts issue stark warning
Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) MEN are more likely than women to get sick and die from three common conditions, warn researchers - and are also less likely to get help for them. There's been strong evidence in the past that sex and gender can substantially influence a person's health. Sign up for Scottish Sun newsletter Sign up 4 Researchers looked at risk factor, development of the condition, diagnosis, treatment and death in men and women for each of the conditions Credit: Getty Men have been found more likely to develop certain heart diseases, while women have a higher risk of osteoporosis. Studies have also suggested women are more likely to experience depression, anxiety, and eating disorders, while men are more likely to struggle with substance abuse and suicide. A new study by Angela Chang of the University of Southern Denmark, and colleagues focused on three conditions - hypertension (high blood pressure), diabetes, and HIV and AIDS. The analysis identified significant differences between the sexes at each step in the 'health pathway". This included exposure to a risk factor, development of the condition, diagnosis, treatment and death. Looking at global health data for people of different sexes and ages for the three conditions, the researchers found men had higher rates of disease and higher rates of death compared to females, and in some countries, were less likely to seek out health care and adhere to treatment. In most countries, men were also more likely to smoke, while women were more like to be obese and engage in unsafe sex. Overall, the study suggests public health professionals need to develop strategies to encourage males to participate in preventive and health care services. Professors Kent Buse and Sarah Hawkes, co-founders and co-CEOs of Global 50/50 said: 'We have long advocated the benefits of publishing sex disaggregated data. "As our Gendered Health Pathways demonstrates, such data can reveal where the health journeys of men and women diverge be it in relation to the risk factors they are exposed to, their health care seeking behaviors or their experiences in health care systems. Diabetes symptoms and the signs of all types of diabetes "That is an important first step towards health equity. "Most of these differences are not explained by sex (biology) alone, but by socially-constructed gender – highlighting the importance of taking a gender justice approach to reducing health inequities. "A gender analysis can help to shape systems of health for all.' Angela Chang, senior author, added: 'The evidence is clear: sex differences persist at nearly every point along the health pathway, from higher smoking rates in men to higher obesity prevalence in women, yet interventions rarely reflect this. "Without sex-disaggregated cascade data, we're flying blind—unable to detect who is falling through the cracks in prevention, diagnosis, and care.' Hypertension 4 High blood pressure can increase your risk of heart attack and stroke Credit: Getty Hypertension, also known as high blood pressure, is a condition where the force of your blood against your artery walls is consistently too high. This means the heart has to work harder to pump blood throughout your body. The condition can lead to serious health problems if not managed, including heart attack and stroke. Hypertension can be caused by a combination of factors, including genetics, lifestyle choices, and underlying medical conditions. A family history of high blood pressure increases your risk of developing it, lifestyle choices such as following an unhealthy diet and smoking can contribute to increased blood pressure, and conditions like kidney disease can play a role in regulating blood pressure. The condition often has no noticeable symptoms, even when blood pressure is dangerously high. The most effective way to determine if you have high blood pressure is through a blood pressure test performed by a healthcare professional or by using a validated home blood pressure monitor. If you have hypertension, the following tips below could help you lower it... How to lower blood pressure Persistent high blood pressure (hypertension) puts extra strain on your blood vessels, heart and other organs and it can raise your risk of serious conditions like heart disease, heart attacks and stroke. Here's how to reduce it. Reduce salt Adults are recommended to limit their salt to 6g per day (around one level teaspoon) to avoid health consequences including high blood pressure. The top tip is to swap out table salt, according to the Salt Substitute and Stroke Study, replacing it with a reduced sodium and added potassium alternative. Cut down on alcohol Excessive boozing can narrow the blood vessels, which raises the risk of hypertension. Official drinking guidelines advise that people should not regularly drink more than 14 units a week to keep health risks from alcohol low. Get moving Exercise is good for the heart and the blood vessels. Although the guidelines recommend 150 minutes of activity per week, if you're currently very inactive, just a walk to the shop every day is better than nothing, and you can work up from there. Studies suggest that isometric exercises - when you hold the body in one position without moving, such as a wall squat or plank - are best for lowering blood pressure. Stop smoking Smoking cigarettes is a killer. It makes the arteries sticky and narrow, which can cause blockages. While smoking is not a direct cause of high blood pressure, it can cause an instant rise to pressure, heart rate and reduce the amount of oxygen that gets to the body's cells. Skip coffee Sadly, caffeine can cause a short, but dramatic increase in your blood pressure - even if you don't have high blood pressure. Therefore cutting back on coffee is recommended as a lifestyle tip for those with hypertension. Lose weight The above tips can help you to lose weight, which is beneficial because being overweight in itself is a risk factor for hypertension. Being overweight forces your heart to work harder to pump blood around your body, which can raise your blood pressure. The only way of knowing whether you have high blood pressure is to have a blood pressure test. All adults over 40 years old are advised to have their blood pressure checked at least every five years. Diabetes 4 High blood sugar levels can lead to serious health problems like heart disease and nerve damage Credit: Getty Diabetes is a chronic metabolic disorder characterized by high blood glucose levels. This occurs when the body either doesn't produce enough insulin or can't properly use the insulin it produces. Insulin is a hormone that helps glucose, a type of sugar, enter cells for energy. When glucose stays in the bloodstream, it can lead to serious health problems over time, such as heart disease, kidney disease, and nerve damage. Diabetes symptoms can vary in severity and how quickly they appear, but some common signs include increased thirst, frequent urination, unexplained weight loss, and feeling very tired. Other potential symptoms include blurred vision, slow-healing wounds, and increased hunger. Type 2 diabetes, the most common form, is often linked to lifestyle factors like obesity and physical inactivity, as well as genetics and age. To lower your risk, follow the steps below... How to lower your risk of type 2 diabetes According to Diabetes UK, there are a few diet tweaks you can make to lower your risk of type 2 diabetes: Choose drinks without added sugar - skip out the sugar in your tea and coffee and stay away from fizzy and energy drinks Eat whole grains such as brown rice, wholewheat pasta, wholemeal flour, wholegrain bread and oats instead of refined carbs Cut down on red and processed meat like bacon, ham, sausages, pork, beef and lamb Eat plenty of fruit and veg - apples, grapes, berries, and green leafy veg such as spinach, kale, watercress, and rocket have been associated with reduced risk of type 2 diabetes Have unsweetened yoghurt and cheese Cut down on booze - and have a few days a week with none at all Have healthy snacks like unsweetened yoghurt, unsalted nuts, seeds and fruit and veg Eat healthy fats included in nuts, seeds, avocados and olive oil Cut down on salt Get your vitamins and minerals from food instead of tablets HIV/AIDS 4 Most cases of HIV in the UK are caused by having sex with a person who has HIV without using a condom Credit: Getty Human immunodeficiency virus (HIV) is a virus that attacks the body's immune system. Acquired immunodeficiency syndrome (AIDS) occurs at the most advanced stage of infection In the UK, most cases of HIV are caused by having sex with a person who has HIV without using a condom. If left untreated, it can lead to serious complications, including a weakened immune system, increased risk of infections and certain cancers, and neurological problems. Most people infected with HIV experience a short, flu-like illness that occurs two to six weeks after infection, says the NHS. After this, HIV may not cause any symptoms for several years. It's estimated up to 80 per cent of people who are infected with HIV experience this flu-like illness. The most common symptoms are a raised temperature (fever), sore throat, and body rash. Other symptoms can include tiredness, joint pain, muscle pain, and swollen glands. The symptoms usually last one to two weeks, but can be longer. They're a sign that your immune system is putting up a fight against the virus. But the NHS advises having these symptoms doesn't necessarily mean you have the HIV virus - they're commonly caused by conditions other than HIV. If you experience several of the symptoms and think you've been at risk of HIV infection, you should get a HIV test. Find out if you're at risk of HIV below... Are you at risk of HIV? HIV is a virus that damages the cells in your immune system and weakens your ability to fight everyday infections and disease. An estimated 106,890 people are living with the condition in the UK. In most cases, it spreads through unprotected sexual contact with an infected person. Most people will experience flu-like symptoms two to six weeks after being infected. This tends to include a sore throat, fever and a rash all over the body, which lasts one to two weeks. After this, HIV may not cause any symptoms at all, but the virus continues to damage your immune system. Some people go on to experience weight loss, night sweats, thrush in the mouth, an increase in herpes or cold sore outbreaks, swollen glands in the groin, neck or armpit, long-lasting diarrhoea, and tiredness. While there is no cure for HIV, there are very effective treatments that enable most people with the virus to live long and healthy lives. Medication now reduces the amount of the virus in the body to the point of being undetectable, meaning it cannot be transmitted. The only way to find out if you have HIV is to have a test. This involves giving a sample of your blood or saliva. The most effective ways to prevent or reduce the risk of infection include using a condom for sex, post-exposure prophylaxis, pre-exposure prophylaxis, treatment for HIV to reduce the viral load to be undetectable, and never sharing needles or other injecting equipment, including syringes, spoons or swabs.

Haunting slave ships found off coast of national park 300 years later: 'Very convincing'
Archaeologists recently made a startling discovery: They found that two 18th-century shipwrecks off the coast of Central America were actually two Danish slave ships. The ships, named Fridericus Quartus and Christianus Quintus, are located in shallow waters off Costa Rica's Cahuita National Park. The 18th-century vessels were shipwrecked in 1710, according to the National Museum of Denmark. "Fridericus Quartus was set ablaze, while Christianus Quintus had its anchor rope cut, following which the ship was wrecked in the surf," the museum's press release noted. "Until now, it has not been clear exactly where the ships were lost." Pictures show divers carefully examining the shipwreck, which shows signs of significant decay from the past 315 years. Though the ships were excavated in 2023, researchers didn't know that they were slave ships until recently. The vessels were long believed to be pirate ships. The excavation involved, in part, taking samples from the wood of the ships, as well as yellow bricks that were part of the ship's cargo. Researchers also conducted dendrochronological analyses — tree-ring dating — to determine where the wood came from. They found it came from Northern Europe. "The timbers originate in the western part of the Baltic Sea, an area that encompasses the northeastern German province of Mecklenburg, as well as Schleswig-Holstein, Denmark and Scania – and that the tree was cut down sometime during the years 1690-1695," the release said. "The wood is, moreover, charred and sooty, which confirms what historical sources say about one of the ships being set ablaze." Divers also found clay pipes, which the museum describes as "ordinary, Dutch-produced pipes that were also used onboard Danish ships." "This provides two pieces that have been missing." "The size, shape and patterns of the pipes suggest that they were produced in the period right before the ships became wrecked in 1710," the press release added. "Clay pipes were rarely used for more than five years." Pictures also show the remarkable yellow bricks that survived the shipwreck, which were produced in Flensburg "for use in Denmark and in the Danish colonies in the 18th and 19th centuries." "In other European countries, other kinds of bricks and stones were in fashion when new buildings were erected," the museum said. "The clay comes from Denmark – quite specifically, from either Iller Strand or Egernsund," the statement added. "Both locations are situated by Flensburg Fjord, which was, in the 18th century, home to a sizeable brick-producing industry." After samples from the excavation were analyzed at the National Museum of Denmark and the University of Southern Denmark, researchers concluded the findings corroborate what historical sources say about the history of the ships. David Gregory, a marine archaeologist at the National Museum of Denmark, said that the results fit "perfectly" with historical accounts about one of the ships burning. "The analyses are very convincing and we no longer have any doubts that these are the wrecks of the two Danish slave ships," Gregory said. "The bricks are Danish and the same goes for the timbers, which are additionally charred and sooty from a fire. This fits perfectly with the historical accounts stating that one of the ships burnt." "We no longer have any doubts that these are the wrecks of the two Danish slave ships." National Museum of Denmark marine archaeologist Andreas Kallmeyer Bloch said he'd "come close to giving up" during the long research process – but is stunned by the results. "This is undoubtedly the craziest archaeological excavation I've yet been part of," Bach said. "Not only because it matters greatly to the local population, but also because it's one of the most dramatic shipwrecks in the history of Denmark, and now we know exactly where it happened." "This provides two pieces that have been missing from the history of Denmark." Fox News Digital reached out to the National Museum of Denmark for additional information.
