The name Kalahari is derived from the Tswana word Kgala, meaning ‘great thirst’. And today the climate at Ga-Mohana, a rock-shelter site in the Kalahari Desert, South Africa, is semi-arid, with little, very seasonal rainfall.

It’s clear that agrochemicals that are highly lethal to insects and weeds can also be extremely dangerous to people. And much of that human harm involves self-poisoning.

In the late 1990s, about 5% of the approximately 4000 bachelor’s degrees in physics per year were earned by Black Americans. Since that time, the representation of Black scientists earning bachelor’s degrees has increased in many fields, including earth sciences, computer science, chemistry, and engineering. But even as undergraduate interest in physics has increased —

One of the biggest mysteries of modern physics is the question of why we don’t see as much antimatter in the universe as ordinary matter. A possible explanation is that antimatter is simply different from ordinary matter in an unknown, but important, way. To explore this possibility, scientists have trapped antimatter to study its properties. However, making precise

In a small study of pregnant women, researchers found that exposure to endocrine-disrupting chemicals commonly found in plastics and products like lipstick, perfumes and lotions – also known as bisphenols (BPA) and phthalates – could contribute to postpartum depression. The study, published in the Journal of Clinical Endocrinology & Metabolism, looked at 139 pregnant women
