The likely source—fertilizer made from sewage sludge—points to a hidden route for contamination. Sat, 11 Apr 2026 08:58:31 EDT https://www.sciencedaily.com/releases/2026/04/260411084441.htm https://www.sciencedaily.com/releases/2026/04/260411081426.htm Scientists have achieved the unthinkable by stabilizing a highly reactive molecule in water, confirming a decades-old theory about vitamin B1’s role in the body. The breakthrough not only solves a scientific mystery but could revolutionize greener chemical manufacturing. Sat, 11 Apr 2026 08:33:37 EDT https://www.sciencedaily.com/releases/2026/04/260411081426.htm https://www.sciencedaily.com/releases/2026/04/260411022029.htm A new study reveals that popular diabetes and weight-loss drugs like Ozempic and Wegovy may not work as effectively for about 10% of people due to specific genetic variants. These individuals appear to have a puzzling condition called “GLP-1 resistance,” where their bodies produce higher levels of the hormone targeted by these drugs—but don’t respond to it properly. Sun, 12 Apr 2026 08:58:54 EDT https://www.sciencedaily.com/releases/2026/04/260411022029.htm https://www.sciencedaily.com/releases/2026/04/260410083114.htm A common eye-health nutrient, zeaxanthin, may also help the body fight cancer more effectively. Scientists discovered it strengthens T cells and enhances the impact of immunotherapy treatments. Found in everyday vegetables and supplements, it’s safe, accessible, and shows strong potential as a cancer therapy booster. Human trials are the next step. Fri, 10 Apr 2026 09:55:45 EDT https://www.sciencedaily.com/releases/2026/04/260410083114.htm https://www.sciencedaily.com/releases/2026/04/260408225950.htm Chronic inflammation often works quietly in the background but can fuel serious diseases like diabetes, heart disease, and cancer. New research reveals that everyday plant compounds—like menthol from mint, cineole from eucalyptus, and capsaicin from chili peppers—can team up inside immune cells to dramatically boost their anti-inflammatory power. While individual compounds showed modest effects, certain combinations amplified results hundreds of times over by activating different cellular pathways at once. Thu, 09 Apr 2026 02:57:22 EDT https://www.sciencedaily.com/releases/2026/04/260408225950.htm https://www.sciencedaily.com/releases/2026/04/260406192913.htm A single week of intensive meditation and mind-body practices led to measurable changes across the brain and body. Researchers observed improved brain efficiency, boosted immune signaling, and increased natural pain relief chemicals in participants’ blood. The effects even promoted neuron growth and stronger brain connectivity. Surprisingly, the experience mirrored psychedelic-like brain states—without any drugs involved. Tue, 07 Apr 2026 03:56:04 EDT https://www.sciencedaily.com/releases/2026/04/260406192913.htm https://www.sciencedaily.com/releases/2026/04/260406192907.htm A surprising new study reveals that what you eat could play a powerful role in fighting cholera, a deadly diarrheal disease. Researchers found that diets rich in certain proteins—especially casein from dairy and wheat gluten—can dramatically reduce the ability of cholera bacteria to take hold in the gut, in some cases cutting infection levels by up to 100 times. These proteins appear to disable a key “weapon” the bacteria use to attack other microbes and dominate the gut environment. Tue, 07 Apr 2026 03:22:01 EDT https://www.sciencedaily.com/releases/2026/04/260406192907.htm https://www.sciencedaily.com/releases/2026/04/260405003949.htm Scientists have identified a potential new weapon against hepatitis E, a virus with no approved treatment and tens of thousands of deaths each year. The drug bemnifosbuvir, currently in trials for hepatitis C, was found to block the virus from replicating by disrupting its genetic machinery. Tests in cells and animals showed strong effectiveness without harming healthy tissue. If ongoing trials succeed, the drug could soon be repurposed for hepatitis E. Mon, 06 Apr 2026 05:00:20 EDT https://www.sciencedaily.com/releases/2026/04/260405003949.htm https://www.sciencedaily.com/releases/2026/04/260403224458.htm Scientists have created an artificial saliva using a sugarcane protein that can protect teeth and fight bacteria. The key ingredient, CANECPI-5, binds directly to enamel, forming a shield against acids that cause decay. Early tests show it works even better when paired with fluoride and xylitol, significantly reducing damage to teeth. The innovation could be especially life-changing for cancer patients who lose saliva production after treatment. Sun, 05 Apr 2026 00:38:05 EDT https://www.sciencedaily.com/releases/2026/04/260403224458.htm https://www.sciencedaily.com/releases/2026/04/260402042751.htm A new clinical trial suggests that what people eat could finally offer real relief for Crohn’s disease, a condition that has long lacked clear dietary guidance. Researchers found that a “fasting-mimicking diet” — involving just five days a month of very low-calorie, plant-based meals — led to noticeable improvements in symptoms for most participants. Even more striking, the diet didn’t just make patients feel better; it also reduced key biological markers of inflammation linked to the disease. Fri, 03 Apr 2026 04:55:54 EDT https://www.sciencedaily.com/releases/2026/04/260402042751.htm https://www.sciencedaily.com/releases/2026/04/260402042744.htm Scientists have created a programmable drug system that can zero in on cancer cells with unprecedented accuracy. Built from synthetic DNA, it only activates when it detects a precise combination of tumor markers, preventing damage to healthy tissue. The system can also deliver multiple drugs at once, potentially overcoming resistance. This marks a step toward medicines that behave more like smart, responsive machines inside the body. Thu, 02 Apr 2026 04:27:44 EDT https://www.sciencedaily.com/releases/2026/04/260402042744.htm https://www.sciencedaily.com/releases/2026/03/260331034337.htm Salt substitutes offer a simple, low-cost way to reduce sodium intake and improve blood pressure, yet very few Americans actually use them—even among those who need them most. A large national analysis spanning nearly two decades found that usage remains surprisingly low and has not improved over time. Researchers say this gap represents a major missed opportunity for preventing heart disease and stroke. Tue, 31 Mar 2026 06:57:40 EDT https://www.sciencedaily.com/releases/2026/03/260331034337.htm https://www.sciencedaily.com/releases/2026/03/260331001107.htm A surprising breakthrough suggests that a drug best known as Viagra could help treat a devastating childhood disease. Researchers found that sildenafil significantly improved symptoms in patients with Leigh syndrome—a rare and often fatal disorder that affects the brain and muscles. In a small study, patients showed stronger muscles, fewer seizures, and better recovery from dangerous metabolic crises, with some experiencing dramatic improvements in mobility and daily life. Tue, 31 Mar 2026 08:33:45 EDT https://www.sciencedaily.com/releases/2026/03/260331001107.htm https://www.sciencedaily.com/releases/2026/03/260330084511.htm A major analysis of nearly 10,000 patients shows that simple, non-drug treatments like knee braces, hydrotherapy, and exercise can significantly ease knee osteoarthritis symptoms. These approaches not only reduce pain and improve mobility, but also avoid the risks tied to common medications. The findings suggest that low-cost, accessible therapies could play a bigger role in how doctors treat arthritis in the future. Mon, 30 Mar 2026 08:52:03 EDT https://www.sciencedaily.com/releases/2026/03/260330084511.htm https://www.sciencedaily.com/releases/2026/03/260330001131.htm A large U.S. study reveals that more than a quarter of people with hard-to-treat high blood pressure may have an overlooked hormone problem. Elevated cortisol—often linked to stress—was found in 27% of these patients, far higher than expected. This hidden condition could explain why standard medications fail. The discovery could lead to new testing and treatments that finally help bring blood pressure under control. Mon, 30 Mar 2026 03:50:56 EDT https://www.sciencedaily.com/releases/2026/03/260330001131.htm https://www.sciencedaily.com/releases/2026/03/260328043558.htm Scientists have developed a new gene therapy that quiets pain at its source in the brain—without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted “off switch” that mimics morphine’s benefits but skips its dangerous side effects. In early tests, it delivered lasting relief without affecting normal sensations. The discovery could mark a major step toward safer, non-addictive pain treatments. Sat, 28 Mar 2026 20:57:04 EDT https://www.sciencedaily.com/releases/2026/03/260328043558.htm https://www.sciencedaily.com/releases/2026/03/260328024519.htm Scientists have uncovered how your body actually tells your brain to stop eating when you’re sick. In a new study, researchers found that specialized cells in the gut detect parasites and send signals that ultimately trigger the brain to suppress appetite. This process builds over time, explaining why you may feel fine at first but then suddenly lose interest in food as an infection takes hold. Sat, 28 Mar 2026 04:35:02 EDT https://www.sciencedaily.com/releases/2026/03/260328024519.htm https://www.sciencedaily.com/releases/2026/03/260326080752.htm Gut bacteria aren’t just passive passengers—they can actively send proteins straight into our cells. Using microscopic injection systems, even harmless microbes can influence immune responses and metabolic pathways. Researchers found these interactions may play a role in inflammatory diseases like Crohn’s. It’s a major shift in how scientists understand the microbiome’s power over human health. Fri, 27 Mar 2026 08:23:14 EDT https://www.sciencedaily.com/releases/2026/03/260326080752.htm https://www.sciencedaily.com/releases/2026/03/260323005545.htm A surprising new study reveals that blocking a supposedly protective enzyme, Caspase-2, could actually backfire—raising the risk of chronic liver damage and cancer over time. Researchers found that without this enzyme, liver cells grow abnormally large and accumulate genetic damage, leading to inflammation, scarring, and eventually tumors, especially with age. While inhibiting Caspase-2 may offer short-term benefits, such as reducing fatty liver disease, the long-term consequences appear dangerous. Mon, 23 Mar 2026 03:13:52 EDT https://www.sciencedaily.com/releases/2026/03/260323005545.htm https://www.sciencedaily.com/releases/2026/03/260323005543.htm Postmenopausal women may have a powerful new edge in the battle against weight gain. A Mayo Clinic study found that those using menopausal hormone therapy while taking the obesity drug tirzepatide lost about 35% more weight than those on the drug alone. The findings hint at a surprising synergy between hormones and cutting-edge weight-loss medications, potentially opening the door to more effective, personalized treatments for millions of women facing increased cardiometabolic risks after menopause. Mon, 23 Mar 2026 21:06:37 EDT https://www.sciencedaily.com/releases/2026/03/260323005543.htm https://www.sciencedaily.com/releases/2026/03/260323005542.htm A new study suggests a widely used bone hormone could help relieve chronic back pain in an unexpected way. Instead of just strengthening bone, it appears to stop pain-sensing nerves from growing into damaged spinal areas. In animal models, this led to stronger spinal tissue and reduced pain sensitivity. The findings hint at a future treatment that tackles back pain at its biological roots. Mon, 23 Mar 2026 22:28:06 EDT https://www.sciencedaily.com/releases/2026/03/260323005542.htm https://www.sciencedaily.com/releases/2026/03/260322020250.htm GLP-1 medications like semaglutide (Ozempic) may offer unexpected mental health benefits alongside weight loss. A large study found major drops in depression, anxiety, and psychiatric-related hospital visits among users. Even substance use disorders were significantly lower during treatment. Researchers suspect both lifestyle improvements and direct brain effects could be at play. Sun, 22 Mar 2026 08:03:11 EDT https://www.sciencedaily.com/releases/2026/03/260322020250.htm https://www.sciencedaily.com/releases/2026/03/260321004445.htm Scientists have engineered probiotic bacteria to act as tumor-seeking drug factories. In mice, these bacteria infiltrated tumors and produced a cancer-fighting drug right where it was needed. This targeted approach could make treatments more effective and reduce side effects. More research is needed before it can be tested in people. Sat, 21 Mar 2026 01:26:09 EDT https://www.sciencedaily.com/releases/2026/03/260321004445.htm https://www.sciencedaily.com/releases/2026/03/260319044648.htm Stopping popular weight-loss injections like Ozempic or Mounjaro might not trigger the dramatic rebound many fear. A large real-world study of nearly 8,000 patients found that most people who discontinue these drugs manage to keep the weight off—or even continue losing—by restarting treatment, switching medications, or adopting lifestyle changes. While earlier clinical trials suggested rapid weight regain, this new evidence paints a more hopeful picture. Thu, 19 Mar 2026 23:08:04 EDT https://www.sciencedaily.com/releases/2026/03/260319044648.htm https://www.sciencedaily.com/releases/2026/03/260318033111.htm Malaria parasites contain tiny spinning crystals that have puzzled scientists for years. New research reveals they’re powered by a rocket-like reaction that breaks down hydrogen peroxide, releasing energy. This motion may help the parasite detoxify harmful chemicals and manage iron more efficiently. The discovery could lead to new drugs and spark innovations in microscopic robotics. Thu, 19 Mar 2026 07:19:27 EDT https://www.sciencedaily.com/releases/2026/03/260318033111.htm https://www.sciencedaily.com/releases/2026/03/260317064444.htm Early life stress may set the stage for long-term digestive problems by disrupting the gut-brain connection. Studies in both mice and thousands of children found links to symptoms like pain, constipation, and IBS. Scientists discovered that different biological pathways control different gut issues, hinting at more personalized treatments in the future. The research also highlights how a child’s early environment can have lasting physical effects—not just emotional ones. Tue, 17 Mar 2026 22:08:54 EDT https://www.sciencedaily.com/releases/2026/03/260317064444.htm https://www.sciencedaily.com/releases/2026/03/260315225125.htm A new UCLA Health study suggests that long-term exposure to the pesticide chlorpyrifos may dramatically raise the risk of Parkinson’s disease. Researchers found that people living in areas with sustained exposure had more than 2.5 times the likelihood of developing the disorder. Lab experiments reinforced the finding: animals exposed to the chemical developed movement problems, lost dopamine-producing neurons, and showed the same toxic protein buildup seen in Parkinson’s patients. Mon, 16 Mar 2026 18:49:45 EDT https://www.sciencedaily.com/releases/2026/03/260315225125.htm https://www.sciencedaily.com/releases/2026/03/260315004407.htm Melatonin is now widely used to help children sleep, but scientists say the enthusiasm may be getting ahead of the evidence. A major review found clear benefits for children with conditions like autism and ADHD, yet far less data exists for typical childhood insomnia. Researchers also warn about mislabeled supplement doses and rising accidental ingestions among young kids. Experts say melatonin should be used carefully and only alongside proven behavioral sleep strategies. Sun, 15 Mar 2026 07:08:26 EDT https://www.sciencedaily.com/releases/2026/03/260315004407.htm https://www.sciencedaily.com/releases/2026/03/260315004403.htm Scientists at MIT have discovered that a little-known protein called intelectin-2 plays a powerful double role in defending the gut. The protein strengthens the mucus layer that lines the gastrointestinal tract while also trapping and disabling harmful bacteria that try to break through. By binding to sugars on both mucus molecules and bacterial surfaces, intelectin-2 forms a protective barrier and can even destroy microbes, including some that resist antibiotics. Mon, 16 Mar 2026 00:05:04 EDT https://www.sciencedaily.com/releases/2026/03/260315004403.htm https://www.sciencedaily.com/releases/2026/03/260313062539.htm Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses an LED lamp to create essential carbon–carbon bonds under mild conditions. This could make drug discovery faster and more environmentally friendly. The breakthrough was uncovered unexpectedly during a failed laboratory experiment. Sat, 14 Mar 2026 01:56:59 EDT https://www.sciencedaily.com/releases/2026/03/260313062539.htm https://www.sciencedaily.com/releases/2026/03/260313002640.htm Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and normalized intestinal movement. The study also found that people with IBS have lower levels of one of these bacteria. The discovery suggests gut microbes could become a powerful new target for treating digestive disorders. Fri, 13 Mar 2026 23:28:29 EDT https://www.sciencedaily.com/releases/2026/03/260313002640.htm https://www.sciencedaily.com/releases/2026/03/260311004824.htm A newly developed antibiotic called EVG7 could offer a powerful new way to stop Clostridioides difficile, a dangerous gut bacterium that often returns after treatment. In mouse studies, researchers found that even a very small dose of EVG7 was highly effective at clearing the infection and preventing it from coming back. Unlike many current antibiotics, which wipe out large portions of the gut microbiome, EVG7 appears to spare beneficial bacteria that naturally help keep C. difficile in check. Wed, 11 Mar 2026 20:19:45 EDT https://www.sciencedaily.com/releases/2026/03/260311004824.htm https://www.sciencedaily.com/releases/2026/03/260309225146.htm Scientists at Oregon Health & Science University have developed a new molecule that could open the door to treating triple-negative breast cancer, one of the most aggressive and difficult-to-treat forms of the disease. The compound, called SU212, targets and disables a key enzyme that cancer cells rely on to fuel their growth. In tests using humanized mouse models, the molecule caused tumors to shrink and slowed the spread of cancer by forcing the enzyme to break down. Tue, 10 Mar 2026 18:10:14 EDT https://www.sciencedaily.com/releases/2026/03/260309225146.htm https://www.sciencedaily.com/releases/2026/03/260307213244.htm A massive UK study of more than 165,000 dementia patients has uncovered troubling new evidence about risperidone, a commonly used drug for severe agitation. Researchers found the antipsychotic increases stroke risk in dementia patients across the board—including those with no prior heart disease or stroke—challenging the long-held belief that some patients might be safer candidates than others. Because risperidone is the only drug of its type licensed for dementia, doctors often use it as a last resort when distressing symptoms become unmanageable. Sun, 08 Mar 2026 16:45:01 EDT https://www.sciencedaily.com/releases/2026/03/260307213244.htm https://www.sciencedaily.com/releases/2026/03/260307213232.htm Scientists are exploring a new way to harness the medical promise of psychedelic compounds without the mind-bending side effects. Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that still target key serotonin pathways linked to depression and other brain disorders but appear to cause far fewer psychedelic-like effects. Sun, 08 Mar 2026 06:26:37 EDT https://www.sciencedaily.com/releases/2026/03/260307213232.htm https://www.sciencedaily.com/releases/2026/03/260306224225.htm A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, shutting down this protein stopped the damage before it could take hold. The finding could pave the way for treatments that protect vision before symptoms ever begin. Sat, 07 Mar 2026 04:48:42 EST https://www.sciencedaily.com/releases/2026/03/260306224225.htm https://www.sciencedaily.com/releases/2026/03/260306145616.htm CBD and CBG, two non-intoxicating cannabis compounds, may help combat fatty liver disease by boosting liver energy reserves and restoring cellular cleanup systems. In the study, both compounds improved blood sugar control and reduced harmful lipids linked to fatty liver disease. Researchers say the findings point to a promising new plant-based approach to treating metabolic liver disorders.

Researchers at Michigan State University discovered that repeated cocaine use rewires communication between the brain’s reward system and the hippocampus, the region responsible for memory. A protein called DeltaFosB builds up with continued drug use and acts like a genetic switch, altering how neurons function and strengthening the brain’s drive to seek cocaine. Fri, 06 Mar 2026 14:45:26 EST https://www.sciencedaily.com/releases/2026/03/260305223211.htm https://www.sciencedaily.com/releases/2026/03/260304184235.htm Scientists have uncovered new genetic rules that determine whether the immune system’s “killer” T cells remain powerful long-term defenders or become worn out and ineffective. By building a detailed genetic atlas of CD8 T cell states, researchers identified key molecular switches that push these cells toward either resilience or exhaustion. Remarkably, disabling just two previously unknown genes restored the tumor-killing power of exhausted T cells while preserving their ability to provide lasting immune protection. Thu, 05 Mar 2026 22:19:10 EST https://www.sciencedaily.com/releases/2026/03/260304184235.htm https://www.sciencedaily.com/releases/2026/03/260304184221.htm Scientists have uncovered a crucial weakness in the malaria parasite that could open the door to new treatments. Researchers identified a protein called Aurora-related kinase 1 (ARK1) that acts like a traffic controller during the parasite’s unusual cell division process, ensuring its genetic material is properly separated as it multiplies. When scientists switched off ARK1 in laboratory experiments, the parasite could no longer replicate correctly and failed to complete its life cycle in both humans and mosquitoes—effectively halting its ability to spread.

In clinical trials, the treatment zorevunersen cut seizures by as much as 91% while also improving quality of life for many patients. The therapy works by boosting the function of a key gene involved in nerve cell signaling. Encouraging results have led researchers to launch a larger Phase 3 trial. Wed, 04 Mar 2026 21:14:30 EST https://www.sciencedaily.com/releases/2026/03/260304184215.htm https://www.sciencedaily.com/releases/2026/03/260303145733.htm Daily aspirin does not reliably prevent bowel cancer in people at average risk, according to a major new review. 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/2026/03/260303145725.htm Stiff knees and aching hips may seem like an inevitable part of aging, but experts say we’re getting osteoarthritis all wrong. Despite affecting nearly 600 million people worldwide — and potentially a billion by 2050 — the most powerful treatment isn’t surgery or medication. It’s exercise. Movement nourishes cartilage, strengthens muscles, reduces inflammation, and even reshapes the biological processes driving joint damage. Wed, 04 Mar 2026 16:35:02 EST https://www.sciencedaily.com/releases/2026/03/260303145725.htm https://www.sciencedaily.com/releases/2026/03/260302030648.htm Researchers are developing a two-part therapy for type 1 diabetes: lab-made insulin-producing cells paired with custom-engineered immune cells that protect them. The goal is to stop the immune system from destroying transplanted cells — without using immunosuppressive drugs. Backed by $1 million in funding, the team hopes to create a ready-to-use treatment that could work even for people who have had diabetes for years. The approach could transform how the disease is treated.

Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building the bacterial cell wall. High-resolution imaging shows these viral proteins lock MurJ into a single position, stopping cell wall construction and leading to bacterial death.

By combining caffeine with CRISPR gene editing, researchers have created a system that allows cells to be programmed in advance — and then activated simply by consuming a small dose of caffeine from coffee, chocolate, or soda. The approach, known as chemogenetics, lets scientists precisely turn gene-editing activity on and off inside targeted cells, including powerful immune T cells that can fight cancer.

People with metabolic syndrome who followed a short, calorie-reduced oat-based plan saw their harmful LDL cholesterol drop by 10%, along with modest weight loss and lower blood pressure. Even more surprising, the cholesterol benefits were still visible six weeks later.

Researchers found that physical activity prompts the liver to release an enzyme that removes a harmful protein causing the blood-brain barrier to become leaky with age. In older mice, dialing down this protein reduced inflammation and improved memory. The discovery points to a surprising body-to-brain pathway that could inspire new Alzheimer’s therapies.

The two microbes break down the colon’s protective mucus layer, leaving stool dry and hard — a problem traditional laxatives don’t fix. Parkinson’s patients, who often struggle with constipation years before tremors appear, have higher levels of these bacteria. Blocking the bacteria’s mucus-destroying enzyme prevented constipation in mice, hinting at a new treatment strategy.
