Hidden blood molecules show surprising anti-aging power | ScienceDaily
Scientists have identified new anti-aging compounds produced by a little-studied blood bacterium. These indole metabolites were able to reduce inflammation, oxidative stress, and collagen-damaging activity in skin cell cultures. Three of the compounds, including two never seen before, showed particularly strong effects. The findings hint at a surprising new source for future skin-rejuvenation therapies.
New study finds cancer-linked compounds in common foods | ScienceDaily
Scientists have found that common foods can contain hidden contaminants formed during cooking or through environmental exposure. A new testing method called QuEChERS helps identify these chemicals more quickly and with greater ease. The research showed strong accuracy and high sensitivity across multiple food samples. This streamlined approach could improve food safety checks while reducing chemical waste.
Doctors are seeing more aggressive breast cancer in younger women than expected | ScienceDaily
Younger women are being diagnosed with breast cancer more often than screening guidelines anticipate. Many of these cancers are invasive and harder to treat, especially in those under 40. After analyzing 11 years of data, researchers found that this age group makes up a steady and significant share of diagnoses. The results support a stronger push for earlier risk evaluation.
