Germ Cells Found to Drive Sex-Dependent Lifespan Differences in Vertebrates

Women live longer than men. This isn't unique to humans, either; we see this trend in a wide range of other animals. Biologists have theorized that the discrepancy in life expectancy between sexes might be partly related to reproduction, but how?

Human Antibodies Offer Hope for Improved Black Widow Antivenom

Sera produced from horses can be used to treat serious illnesses caused by black widow bites. But this approach is not totally secure. To address this, scientists have produced entirely human antibodies that are capable of neutralizing the European black widow's alpha-latrotoxin.

Study Unveils Broader Immune Response in EBV-MS Connection

Epstein-Barr virus (EBV) may have a greater effect on the development of multiple sclerosis (MS) than previously believed due to a higher level of cross-reactivity, which occurs when the immune system binds to the incorrect target.

Multiciliated Cell Differentiation Regulated by an Alternative Cell Cycle

A fertilized egg can develop into a baby through the amazing process of cell division, while a malignant cell can become a malignant tumor. Since there is so much on the line, nature maintains strict control over it through a mechanism known as the cell cycle that scientists once believed they thoroughly understood.

Study Unveils Key Mechanism of Telomere Maintenance by CST–Polα/Primase

The length of telomeres that protect the ends of our chromosomes should be tightly regulated. Those that are too long predispose to cancer, and those that are too short lose their protective ability, resulting in telomere disorders with serious health consequences.
