- newA hidden T cell switch could make cancer immunotherapy work for more people
Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before. This breakthrough may help explain why immunotherapy works for some cancers and how it could be improved for others.

- newYoung adults are using cannabis to sleep at alarming rates
More than 20% of young adults say they use cannabis or alcohol to fall asleep, with cannabis leading by a wide margin. Researchers warn this strategy can backfire, disrupting sleep quality and increasing the risk of long-term sleep and substance-use problems.

- newAI detects cancer but it’s also reading who you are
AI tools designed to diagnose cancer from tissue samples are quietly learning more than just disease patterns. New research shows these systems can infer patient demographics from pathology slides, leading to biased results for certain groups. The bias stems from how the models are trained and the data they see, not just from missing samples. Researchers also demonstrated a way to significantly reduce these disparities.

- newThis tiny protein helps control how hungry you feel
Researchers have identified a previously overlooked protein that helps regulate appetite and energy use in the body. This “helper” protein supports a key system that decides whether the body burns energy or stores it, and when it does not function properly, appetite signals can weaken.

- Scientists rewired Down syndrome brain circuits by restoring a missing molecule
A missing brain molecule may be disrupting neural wiring in Down syndrome, according to new research. Replacing it in adult mice rewired brain circuits and improved brain flexibility, challenging the idea that treatment must happen before birth.

- He ate a hamburger and died hours later. Doctors found a shocking cause
A rare tick-borne allergy linked to red meat has now been confirmed as deadly for the first time. A healthy New Jersey man collapsed and died hours after eating beef, with later testing revealing a severe allergic reaction tied to alpha-gal, a sugar spread by Lone Star tick bites. Symptoms often appear hours later, making the condition easy to miss. Researchers warn that growing tick populations could put more people at risk.

- New study reveals how kimchi boosts the immune system
Kimchi may do far more than add flavor to meals—it could help fine-tune the human immune system. A clinical study using advanced single-cell genetic analysis found that regular kimchi consumption strengthens immune defenses while preventing harmful overreactions. Researchers observed improved activity in key immune cells, with effects varying depending on fermentation methods.

- A new test could reveal Alzheimer’s before symptoms appear
Scientists at Northern Arizona University are developing a promising new way to detect Alzheimer’s disease earlier than ever before—by tracking how the brain uses sugar. Using tiny particles in the blood called microvesicles, researchers may soon be able to gather brain-specific information without invasive procedures. If successful, this approach could transform Alzheimer’s diagnosis, monitoring, and even prevention, much like how doctors manage heart disease today.

- Scientists reveal why some brains stop growing too soon
Researchers used miniature human brains grown in the lab to uncover why certain genetic mutations lead to abnormally small brains. Changes in actin disrupted the orientation of early brain cell divisions, causing crucial progenitor cells to disappear too soon. This reduced the brain’s ability to grow normally. The work offers a clear cellular explanation for microcephaly linked to Baraitser-Winter syndrome.

- Colon 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.

- A 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.

- Scientists 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.

- AI learns to decode the diseases written in your DNA
A newly developed AI can predict which diseases specific genetic mutations are likely to cause, not just whether they are harmful. The breakthrough could speed up diagnoses and open new paths for personalized treatment.

- 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.
