Discover how desert-loving fungi and lichens are threatening 5,000-year-old rock art in the Negev desert of southern Israel. Learn about the acids secreted by these organisms that can erode the ancient petroglyphs and the efforts needed to protect this cultural treasure for future generations.

New Mathematical Model Sheds Light on Absence of Breastfeeding in Male Mammals

New mathematical model sheds light on absence of breastfeeding in male mammals. Study proposes evolutionary strategy to control spread of harmful microbes. Owl monkey fathers and Dayak fruit bats challenge traditional theories. Male avoidance of breastfeeding may be linked to diverse milk microbiome. Research offers fresh perspective on parental care and microbial transmission in mammalian populations.

Study Reveals Surprising Insights into Frogs’ Light-Sensing Abilities

A recent study led by a Penn State biologist reveals the crucial role of nonvisual opsins in frogs’ light-sensing abilities. These proteins play key roles in regulating circadian rhythms, melatonin release, pupil response, and adaptation to seasonal changes. The research, published in Molecular Biology and Evolution, emphasizes the significance of nonvisual light sensitivity in biological processes and the need for further exploration in this area.

New Evidence Supports Younger Dryas Impact Hypothesis

Discover the controversial Younger Dryas impact hypothesis and how it may have led to the extinction of wooly mammoths. Archaeologist Christopher Moore and his colleagues believe they have found evidence of a cometary impact around 12,800 years ago, based on minerals with unique properties found in sediment layers across the globe.
