Their experimental approach combines focused ultrasound, tiny nanoparticles, and genetic molecules called microRNAs to attack multiple cancer-driving genes simultaneously.

Scientists at Johns Hopkins have uncovered a crucial missing link between a common gut bacterium and colorectal cancer, solving a mystery that has puzzled researchers for nearly two decades. The bacterium, Bacteroides fragilis, produces a toxin that damages the colon’s protective lining, triggers chronic inflammation, and promotes tumor formation.

Scientists at Johns Hopkins University have uncovered a surprising process that helps humans develop sharp vision before birth, challenging decades of assumptions about how the eye forms. Using miniature human retinas grown in the lab, researchers discovered that a vitamin A derivative and thyroid hormones work together to shape the foveola, the tiny region at the center of the retina responsible for our sharpest vision.

Scientists have uncovered hidden aggressive cancer cells in children whose tumors were previously considered lower risk, revealing why some cases of rhabdomyosarcoma become unexpectedly deadly. The discovery could help doctors identify dangerous tumors earlier and develop personalized treatments that improve survival while reducing unnecessary chemotherapy.

A surprising discovery reveals that widely used anti-inflammatory drugs may unintentionally help dangerous viruses spread through the body. Scientists found that JAK inhibitors, prescribed for rheumatoid arthritis and other inflammatory diseases, can weaken a crucial immune defense against influenza, COVID-19, and other infections. By suppressing genes that normally fight viruses, these medications may leave patients more vulnerable to infection.

A powerful new AI system could help doctors detect pancreatic cancer years before it becomes visible on conventional scans. The technology, called REDMOD, identified hidden warning signs an average of 475 days before diagnosis and was nearly twice as sensitive as experienced radiologists. By spotting cancer-related changes at their earliest stages, it could dramatically improve the chances of successful treatment for one of the deadliest forms of cancer.

Scientists have discovered how pancreatic cancer cells continually reshape their genetic makeup to become more aggressive, spread, and evade treatment. In laboratory experiments, blocking a key gene reversed some of these dangerous changes, revealing a potential new way to fight the deadly disease.

Scientists discovered that the thick, sticky fluid surrounding glioblastoma tumors can make brain cancer cells smaller, more flexible, and better at invading surrounding tissue. Even more troubling, some of these changes persist after the cells leave the thick fluid, revealing a previously overlooked mechanism that could help this deadly cancer spread.

Researchers have uncovered a hidden immune defense capable of attacking small cell lung cancer, an extremely aggressive disease that often escapes conventional treatments. The specialized immune cells can recognize and destroy cancer cells even when tumors have disguised themselves from the immune system.

Scientists have captured virus-like particles assembling themselves step by step, revealing how a surprisingly simple process of trial and error produces complex structures with remarkable precision. The discovery uncovers a crucial molecular turning point that speeds up assembly and could lead to new ways to disrupt viruses and develop vaccines.

Scientists have uncovered a surprising reason why statins, the widely prescribed cholesterol-lowering drugs that help prevent heart attacks and strokes, can sometimes cause muscle pain, weakness, and even severe muscle damage. Using advanced imaging technology, researchers discovered that statins can attach to a crucial protein in muscle cells and force open a channel that normally controls calcium flow. This causes calcium to leak continuously, potentially damaging muscle tissue.

A surprising clinical trial suggests that taking vitamin C daily could improve survival in people with precancerous blood disorders and early-stage blood cancers. Patients receiving the supplement had fewer adverse events and showed a promising survival advantage, raising hopes that a common vitamin could help protect against leukemia-related complications.

Scientists have uncovered a surprising difference in how male and female skin repairs and renews itself. By tracking individual skin stem cells in living mice for five months, researchers discovered that female cells work together in a highly coordinated way, while male cells operate more independently. This synchronization, driven by sex hormones, helps explain why wounds heal faster in female mice, especially during the first few days.

USC scientists have discovered a way to create a potentially renewable supply of genetically engineered immune cells that can attack cancer and strengthen the body's natural defenses. By growing and modifying immature immune cells rather than mature ones, researchers developed a system that can continuously produce tumor-fighting cells inside the body.

Scientists have discovered how to turn a protein that normally fuels cancer growth into a weapon against it. By activating PPARD in immune cells, researchers made them better at burning fat and attacking tumors, slowing or stopping cancer growth in laboratory experiments. The approach showed promise against colorectal, breast, and ovarian cancers, as well as melanoma.

Scientists have discovered that unusually small cancer cells carrying extra chromosomes can be far more aggressive than larger ones, growing faster, spreading more readily, and resisting common treatments. The surprising finding could help explain why some tumors are especially dangerous and provide a new way to predict cancer outcomes.

A major study found that several cancers are rising faster among younger adults in England, even as smoking, diet, and other established risk factors have generally improved. Excess weight explains only part of the increase, leaving scientists searching for other possible causes, including changes in the gut microbiome and early-life exposures.

A short course of immunotherapy before surgery may offer remarkably durable protection for some patients with stage two or three bowel cancer. In the NEOPRISM-CRC trial, 32 patients with a specific genetic form of bowel cancer received pembrolizumab for up to nine weeks before surgery instead of the usual post-surgery chemotherapy. After nearly three years of follow-up, none of the patients had experienced a cancer recurrence, including those who still had small traces of disease after treatment.

Chronic diabetic wounds may fail to heal because immune cells remain locked in damaging inflammatory states instead of transitioning toward tissue repair. Researchers are exploring treatments that reprogram these immune responses, raising hopes for more targeted and effective therapies for diabetic ulcers.

Not all vitamin D supplements are created equal, and new research suggests that one popular form may have an unexpected downside. Scientists found that taking vitamin D2 can actually lower the body's levels of vitamin D3, the form naturally produced by sunlight and more effective at boosting overall vitamin D. Previous studies also suggest that vitamin D3 may provide stronger immune protection against viruses and bacteria.

A Stanford-designed molecule turns a major lymphoma-promoting protein against cancer cells, activating their own self-destruct machinery instead of simply blocking tumor growth. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days, although much more testing is needed before it could reach patients.

Eating more sugar while taking antibiotics was linked to greater disruption of the gut microbiome and increased growth of potentially harmful bacteria. Researchers say temporarily cutting back on sweets during and after antibiotic treatment could be a simple way to reduce this damage, though clinical trials are still needed.

Blocking a receptor called P2X7 significantly reduced inflammation in human brain tissue, revealing a potential new treatment strategy for neurological and psychiatric disorders. The discovery could help researchers repurpose existing drugs for conditions including traumatic brain injury, Alzheimer’s, Parkinson’s, depression, and schizophrenia.

Scientists at UC San Francisco have developed a way to create cancer-fighting CAR-T cells directly inside the body, potentially avoiding the slow and extremely expensive process of removing, engineering, and reinfusing a patient’s immune cells. Using a two-particle delivery system, the researchers sent CRISPR gene-editing tools and new cancer-targeting DNA specifically into T cells, where the DNA was inserted at a precise location in the genome.

A ketogenic diet increased small-intestinal tumors in cancer-prone mice while reducing tumors in the colon, revealing a strikingly different response within neighboring parts of the gut. Researchers traced the increased risk not to ketones, but to the way intestinal stem cells processed the diet’s high levels of fat. That fat-burning activity pushed the cells to multiply more rapidly, potentially raising the chance of cancerous changes.

A new nanoparticle therapy reduced lung tumors in mice while also targeting cachexia, the severe muscle wasting that can accompany cancer. By delivering follistatin mRNA directly to tumors, the approach could eventually offer a way to fight both the disease and one of its most dangerous complications.

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn through their energy while producing cancer-killing proteins. In animal and laboratory studies, blocking MEK helped the cells conserve energy, survive longer, and remain active even in the harsh environment around tumors.

High-dose vitamin B3 is showing intriguing early promise as an addition to standard glioblastoma treatment, with 82% of patients in a small trial remaining progression-free after six months. Researchers believe niacin may help revive immune cells suppressed by the cancer, but larger studies are still needed to confirm the benefit and safety.

A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors had high levels of the vitamin D receptor.

Vitamin C may do more than support the immune system. In a phase 2 trial of people with precancerous or low risk blood cancers, daily vitamin C did not slow abnormal cell growth, but it was linked to favorable changes in inflammation and fewer serious complications. An exploratory follow up also found fewer deaths among participants taking vitamin C than among those receiving placebo.

Scientists have mapped the genetics of cat cancer on an unprecedented scale and found surprising similarities with tumors in humans. The findings could help bring precision cancer treatments to cats while also revealing new clues about how human cancers develop and respond to drugs.

A new analysis suggests mammograms may lead to far less breast cancer overdiagnosis than some earlier studies indicated. Researchers reexamined all eight major randomized screening trials and accounted for differences in follow-up time, screening frequency, and screening after trials ended. Their results were consistent with an overdiagnosis rate below 5%, rather than estimates approaching 30% to 50%.

Researchers used CRISPR to remove CD33 from donor stem cells, potentially giving doctors a way to attack aggressive blood cancers without destroying the healthy cells patients need after a transplant. In a 30-patient trial, the edited cells successfully took hold and appeared to shield blood cells from a CD33-targeted cancer treatment.

A new experimental drug called CS18 may help break through cancer drug resistance by disabling several of the defenses tumors use to survive treatment. It strengthened existing therapies, restored drug sensitivity in resistant lung cancer cells, and slowed tumor growth in animal models.

A sweeping review of more than 153,000 adults found that calcium and vitamin D supplements, alone or together, do little to prevent fractures or falls in most older people. Researchers say the findings challenge routine supplementation for prevention and point instead toward strategies such as balance and resistance exercise.

A growing Bundibugyo virus outbreak is showing how a little-known relative of Ebola can become a major threat when diagnosis and treatment options are limited. Experts warn that preparing only for familiar pathogens could leave the world vulnerable when rare but deadly viruses suddenly reemerge.
