Researchers found that evolocumab, typically used for people who already have cardiovascular disease, can significantly cut the risk of first-time heart attacks and strokes in high-risk patients with diabetes—even before any artery-clogging plaque is detected. Mon, 30 Mar 2026 03:29:23 EDT https://www.sciencedaily.com/releases/2026/03/260330001129.htm https://www.sciencedaily.com/releases/2026/03/260328043556.htm After a stroke, the brain may do something surprisingly hopeful—it can “refresh” parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite, unaffected side can actually look younger. This unexpected shift seems to reflect the brain’s effort to rewire itself, strengthening healthy regions to compensate for lost function.

It urges people to start screening sooner—sometimes even in childhood—and highlights the importance of tracking not just LDL (“bad”) cholesterol but also genetic risk factors like lipoprotein(a). A new, more advanced risk calculator now uses broader health data to better predict heart attack and stroke risk over decades.

This area, which kicks in during forceful exhalations like coughing, laughing, or exercise, also appears to activate nerves that tighten blood vessels—raising blood pressure. When researchers switched off this region in experiments, blood pressure dropped back to normal, suggesting it plays a direct role in hypertension.

Researchers found that belly fat was more strongly linked to heart failure risk than BMI, even in people with normal weight. Inflammation seems to play a key role, helping explain why this type of fat is especially harmful. Measuring waist size could offer a simple way to detect hidden risk earlier.

Any potential protective effect may take more than a decade to appear — if it appears at all — and the evidence for that benefit is weak. In contrast, the risk of serious bleeding begins right away, even with low-dose aspirin. Experts warn that prevention decisions should be individualized, not automatic. Wed, 04 Mar 2026 18:12:30 EST https://www.sciencedaily.com/releases/2026/03/260303145733.htm https://www.sciencedaily.com/releases/2026/02/260227061818.htm Heart disease is on track to tighten its grip on American women. New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, diabetes, and obesity. By 2050, nearly 60% of women in the U.S. could have high blood pressure, and close to one in three women ages 22 to 44 may already be living with some form of heart disease. Fri, 27 Feb 2026 06:18:18 EST https://www.sciencedaily.com/releases/2026/02/260227061818.htm https://www.sciencedaily.com/releases/2026/02/260224023159.htm Subtle changes in brain blood flow and oxygen use are closely linked to hallmark signs of Alzheimer’s, including amyloid plaques and memory-related brain shrinkage. Simple, noninvasive scans may one day help spot risk earlier—by looking at the brain’s vascular health, not just its plaques. Tue, 24 Feb 2026 10:21:58 EST https://www.sciencedaily.com/releases/2026/02/260224023159.htm https://www.sciencedaily.com/releases/2026/02/260222092306.htm A UCLA study in mice reveals that aging muscle stem cells accumulate a protein that slows repair but boosts survival. This protein, NDRG1, acts like a brake, preventing cells from activating quickly after injury. When researchers blocked it in older mice, muscle healing sped up dramatically — but stem cells became less resilient over time. The work suggests aging may reflect a survival trade-off rather than straightforward decline. Mon, 23 Feb 2026 23:02:05 EST https://www.sciencedaily.com/releases/2026/02/260222092306.htm https://www.sciencedaily.com/releases/2026/02/260212025620.htm A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging. Thu, 12 Feb 2026 09:42:41 EST https://www.sciencedaily.com/releases/2026/02/260212025620.htm https://www.sciencedaily.com/releases/2026/02/260206012203.htm Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain’s ability to produce dopamine, the chemical whose loss drives Parkinson’s disease. The early-stage clinical trial involves implanting lab-grown dopamine-producing cells directly into a key movement-control region of the brain, with the hope of slowing disease progression and improving motor function. Fri, 06 Feb 2026 06:57:35 EST https://www.sciencedaily.com/releases/2026/02/260206012203.htm https://www.sciencedaily.com/releases/2026/01/260130041056.htm Men start developing heart disease earlier than women, with risks rising faster beginning around age 35, according to long-term research. The difference is driven mainly by coronary heart disease, not stroke or heart failure. Traditional risk factors explain only part of the gap. The findings suggest earlier screening could help catch problems before serious damage occurs. Fri, 30 Jan 2026 10:52:51 EST https://www.sciencedaily.com/releases/2026/01/260130041056.htm https://www.sciencedaily.com/releases/2026/01/260121034130.htm New research suggests that consistent aerobic exercise can help keep your brain biologically younger. Adults who exercised regularly for a year showed brains that appeared nearly a year younger than those who didn’t change their habits. The study focused on midlife, a critical window when prevention may offer long-term benefits. Even small shifts in brain age could add up over decades. Thu, 22 Jan 2026 01:51:37 EST https://www.sciencedaily.com/releases/2026/01/260121034130.htm https://www.sciencedaily.com/releases/2026/01/260120095116.htm Scientists have uncovered why people with chronic kidney disease so often die from heart problems: damaged kidneys release tiny particles into the bloodstream that actively poison the heart. These particles, produced only by diseased kidneys, carry genetic material that disrupts heart function and can lead to heart failure. Tue, 20 Jan 2026 10:40:35 EST https://www.sciencedaily.com/releases/2026/01/260120095116.htm https://www.sciencedaily.com/releases/2026/01/260120000323.htm Ibuprofen may be doing more than easing aches and pains—it could also help reduce the risk of some cancers. Studies have linked regular use to lower rates of endometrial and bowel cancer, likely because the drug dampens inflammation that fuels tumor growth. Researchers have even found it can interfere with genes cancer cells rely on to survive. Still, experts warn that long-term use carries risks and shouldn’t replace proven prevention strategies. Tue, 20 Jan 2026 03:47:11 EST https://www.sciencedaily.com/releases/2026/01/260120000323.htm https://www.sciencedaily.com/releases/2026/01/260112001001.htm Most U.S. adults have risk factors tied to a little-known condition called CKM syndrome, which connects heart disease, kidney problems, diabetes, and obesity into one powerful health threat. When these issues overlap, the danger rises far more than when they occur alone. Despite low awareness, people are eager to learn how CKM is diagnosed and treated. Experts say understanding how these systems work together could prevent serious, life-threatening events. Mon, 12 Jan 2026 00:10:01 EST https://www.sciencedaily.com/releases/2026/01/260112001001.htm https://www.sciencedaily.com/releases/2026/01/260103155034.htm Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying donated human hearts found that diabetes disrupts how heart cells produce energy, weakens the muscle’s structure, and triggers a buildup of stiff, fibrous tissue that makes it harder for the heart to pump. These changes are especially severe in people with ischemic heart disease, the most common cause of heart failure. Sun, 04 Jan 2026 00:34:03 EST https://www.sciencedaily.com/releases/2026/01/260103155034.htm https://www.sciencedaily.com/releases/2025/12/251228013705.htm As spinal cord injuries increasingly affect older adults, new research reveals a surprising pattern in recovery. The study shows that aging does not appear to slow the healing of nerves themselves, with older patients regaining strength and sensation at rates similar to younger people. However, age makes a clear difference in how well people recover everyday abilities like walking, mobility, and self-care. Sat, 03 Jan 2026 03:48:46 EST https://www.sciencedaily.com/releases/2025/12/251228013705.htm https://www.sciencedaily.com/releases/2025/12/251227082716.htm Stanford scientists have uncovered how mRNA COVID-19 vaccines can very rarely trigger heart inflammation in young men — and how that risk might be reduced. They found that the vaccines can spark a two-step immune reaction that floods the body with inflammatory signals, drawing aggressive immune cells into the heart and causing temporary injury. Sat, 27 Dec 2025 10:52:27 EST https://www.sciencedaily.com/releases/2025/12/251227082716.htm https://www.sciencedaily.com/releases/2025/12/251224032354.htm Alzheimer’s has long been considered irreversible, but new research challenges that assumption. Scientists discovered that severe drops in the brain’s energy supply help drive the disease—and restoring that balance can reverse damage, even in advanced cases. In mouse models, treatment repaired brain pathology, restored cognitive function, and normalized Alzheimer’s biomarkers. The results offer fresh hope that recovery may be possible. Wed, 24 Dec 2025 10:14:26 EST https://www.sciencedaily.com/releases/2025/12/251224032354.htm https://www.sciencedaily.com/releases/2025/11/251126095026.htm The study reveals that widely used heart-attack risk calculators fail to flag nearly half of those who will soon experience a cardiac event. Even the newer PREVENT model misclassifies many patients as low-risk. Since most people develop symptoms only within 48 hours of their heart attack, current screening offers little time for intervention. Researchers say earlier detection with imaging could dramatically improve prevention. Thu, 27 Nov 2025 08:07:49 EST https://www.sciencedaily.com/releases/2025/11/251126095026.htm https://www.sciencedaily.com/releases/2025/11/251126095018.htm Researchers at Stanford found a way to cure or prevent Type 1 diabetes in mice using a combined blood stem cell and islet cell transplant. The procedure creates a hybrid immune system that stops autoimmune attacks and eliminates the need for immune-suppressing drugs. The method uses tools already common in clinical practice, putting human trials within reach. Scientists think the same strategy could transform treatments for autoimmune conditions and organ transplantation.

Even physically fit men weren’t protected unless they had consumed flavanols beforehand. A cocoa drink rich in these compounds kept arteries functioning normally. Everyday foods like berries, apples, tea, and certain cocoa products could offer a simple way to protect long-term vascular health.

The antibody, briquilimab, removes diseased stem cells without radiation, enabling nearly complete donor cell replacement. The approach also widens donor eligibility and could soon be applied to other bone marrow failure diseases.

The key lies in serine, an amino acid that activates a stress signal telling cells to conserve energy. When both injury and low serine occur, stem cells fully pivot to skin repair. The discovery could lead to dietary or medical ways to boost healing.

Their stem cells ignore nearby instructions and respond to long-distance signals from other tissues. This discovery turns old stem cell theories upside down and could lead to new ways to repair or regrow human tissue. It also reveals a hidden complexity in one of nature’s simplest creatures.

Their MRI-based study of over 33,000 adults shows these fats are closely linked to artery thickening and stroke risk, regardless of cholesterol or blood pressure. The findings challenge BMI as a reliable indicator of health and suggest new imaging-based approaches to assessing cardiovascular risk.

This discovery explains why dangerous, fast heart rhythms can strike after an infarction. By removing this molecule in mice, the researchers reduced deadly arrhythmias twelvefold, suggesting that targeting immune-driven damage could open a new path to preventing sudden cardiac death.

In both humans and mice, a few stem cells out-compete their neighbors and gradually take over blood production. The loss of diversity results in a blood system that has a preference for producing myeloid cells, immune cells linked to chronic inflammation which underlies many different diseases. Using a new technique, researchers tracked naturally-occurring 'barcodes' in blood cells which can lead to new strategies that spot early warning signs of unhealthy aging long before symptoms appear, helping prevent cancer or heart disease. The technique also opens the door to studying the viability of rejuvenation therapies in humans, efforts which have traditionally been the focus of animal research.

The new framework expands the assessment beyond immediate clinical symptoms. Added criteria would include biomarkers, CT and MRI scans, and factors, such as other medical conditions and how the trauma occurred.
