Ancient Lead Poisoning May Have Shaped Human Evolution
New findings challenge the idea that lead exposure is a modern problem A recent study published in Science Advances proposes a provocative reversal of conventional wisdom: lead poisoning may have been a feature of the evolutionary landscape long before the Industrial Revolution. The international team behind the work argues that lead and other toxic metals…

New MAEA function could help overcome chemo resistance in cancer treatment
New MAEA function in DNA repair offers a potential route to overcoming chemotherapy resistance A University of Alberta research team has identified a surprising new role for a protein once thought to be linked primarily to red blood cell development. The protein, macrophage erythroblast attacher (MAEA), appears to help regulate DNA repair and cell replication.…

Not Just Women: Men Also Face a Biological Clock
Rethinking the Biological Clock in Fertility For decades, public discourse on fertility has centered on women, often framing age as the sole determinant of reproductive success. The saying that a woman’s biological clock speeds up in her late 30s or 40s has shaped medical advice, personal decisions, and social expectations. But a growing body of…

Molecular Coating Tames Noisy Quantum Light Emission
Overview: A cleaner, more reliable quantum light source Quantum technologies demand perfection: one photon at a time with identical energy. Even tiny variations in photon number or energy can derail devices and threaten the performance of quantum computers that may form a quantum internet. In response, Northwestern University engineers developed a simple, scalable solution that…

The Science Behind Gender Selection in Pregnancies
For years, many believed that conceiving a boy or a girl was merely a matter of chance, like a coin toss with equal odds. However, a groundbreaking study published on July 18, 2025, in Science Advances challenges this notion. Researchers analyzed extensive data and found that biological and environmental factors significantly influence a couple’s likelihood…
