- newColon cancer is surging in younger adults and doctors are alarmed
Cases of colorectal cancer in younger adults are climbing worldwide, driven by lifestyle changes and inherited genetic risks. Diet, obesity, and lack of early screening are playing a major role in this shift. New genetic tests offer hope for earlier detection, but access and awareness lag behind. Health experts say urgent action is needed to reverse the trend.

- newA new way to prevent gum disease without wiping out good bacteria
Scientists are uncovering a surprising way to influence bacteria—not by killing them, but by changing how they communicate. Researchers studying oral bacteria found that disrupting chemical signals used in bacterial “conversations” can shift dental plaque toward healthier, less harmful communities. The discovery could open the door to new treatments that prevent disease by maintaining a balanced microbiome rather than wiping bacteria out entirely.

- newScientists find the missing links between genes and disease
A new genetic mapping strategy reveals how entire networks of genes work together to cause disease, filling in the missing links left by traditional genetic studies. The technique could transform how scientists identify drug targets for complex conditions.

- Why consciousness exists at all
Consciousness evolved in stages, starting with basic survival responses like pain and alarm, then expanding into focused awareness and self-reflection. These layers help organisms avoid danger, learn from the environment, and coordinate socially. Surprisingly, birds show many of these same traits, from subjective perception to basic self-awareness. This suggests consciousness is far older and more widespread than once believed.

- AI found a way to stop a virus before it enters cells
Researchers discovered a hidden molecular “switch” that herpes viruses rely on to invade cells. By combining AI, simulations, and lab experiments, they identified and altered a single amino acid that shut down viral entry. What once might have taken years was achieved far faster using computational tools. The findings open new possibilities for designing future antiviral treatments.

- New study shows some plant-based diets may raise heart disease risk
Researchers tracking over 63,000 adults found that high-quality, minimally processed plant foods significantly reduce cardiovascular risk. But when those plant foods are ultra-processed, the advantage disappears—and can even backfire. Some ultra-processed plant diets increased risk by 40%. The study urges a shift toward whole, naturally nutrient-rich plant foods.

- These simple habits could make your brain 8 years younger, study finds
New research shows that your brain’s “true age” can shift dramatically depending on how you live, with optimism, restorative sleep, stress management, and strong social support acting like powerful anti-aging tools. Using advanced MRI-based brain-age estimates, scientists found that people with multiple healthy lifestyle factors had brains up to eight years younger than expected — even among those living with chronic pain.

- Anxiety and insomnia linked to sharp drops in key immune cells
Natural killer cells act as the immune system’s rapid-response team, but the stress of anxiety and insomnia may be quietly thinning their ranks. A study of young women in Saudi Arabia found that both conditions were linked to significantly fewer NK cells—especially the circulating types responsible for destroying infected or abnormal cells. As anxiety severity increased, NK cell levels dropped even further, suggesting a stress-driven weakening of immune defenses.

- Cannabis compounds show unexpected power against ovarian cancer
Scientists have discovered that key compounds from cannabis—CBD and THC—show surprisingly strong effects against ovarian cancer cells. Used together, they slow cell growth, reduce colony formation, and may even block the cancer’s ability to spread. Even more promising, the treatment caused minimal harm to healthy cells and appears to work by restoring a disrupted signaling pathway that fuels tumor growth.

- Mayo Clinic neurosurgeon reveals 8 back pain myths to stop believing
Back pain is wrapped in persistent myths, but many are far from the truth. From misconceptions about heavy lifting and bed rest to confusion over posture, exercise, and surgery, Dr. Meghan Murphy breaks down what really causes pain and what actually helps. Her insights reveal that everyday habits, movement, and smart prevention often make a bigger difference than people realize.

- Stem cell pain sponge soaks up osteoarthritis joint pain and protects cartilage
SereNeuro Therapeutics revealed promising results for SN101, a first-in-class iPSC-derived therapy designed to treat chronic osteoarthritis pain while protecting joint tissue. Instead of blocking pain pathways, SN101 uses lab-grown nociceptors that act like sponges, soaking up inflammatory pain factors without sending pain signals. These cells also release regenerative molecules, offering disease-modifying potential that stands apart from traditional corticosteroids and single-target drugs like…

- Indoor tanning triples melanoma risk and seeds broad DNA mutations
Researchers discovered that tanning beds cause widespread, mutation-laden DNA damage across almost all skin, explaining the sharply increased melanoma risk. Single-cell genomic analysis revealed dangerous mutations even in sun-protected regions. Survivors’ stories underscore how early tanning habits have lifelong consequences. The findings push for stricter policies and clear public warnings.

- Researchers identify viral suspects that could be fueling long COVID
Scientists are uncovering a new possibility behind long COVID’s stubborn symptoms: hidden infections that awaken or emerge alongside SARS-CoV-2. Evidence is mounting that viruses like Epstein-Barr and even latent tuberculosis may flare up when COVID disrupts the immune system, creating lingering fatigue, brain fog, and other debilitating issues.

- Harvard gut discovery could change how we treat obesity and diabetes
Scientists found that certain molecules made by gut bacteria travel to the liver and help control how the body uses energy. These molecules change depending on diet, genetics, and shifts in the microbiome. Some even improved insulin response in liver cells when tested in the lab. The findings could open the door to new ways of preventing or managing obesity and diabetes.
