A Tiny but Mighty Helper Stops Mosquito Viruses in Their Tracks

<em >Wolbachia</em> bacteria, marked in green, are found in a wasp&rsquo;s egg, where the wasp&rsquo;s DNA is shown in blue.

A Microbial Ally to Bring Science to the Masses

The infographic shows a new method where researchers used spider webs to monitor environmental eDNA of vertebrates. They demonstrated the effectiveness of their by analyzing samples from a zoo and a wildlife sanctuary.

A Spider-Web Trap to Monitor Environmental DNA

A cross section of the pistil of <em >Arabidopsis thaliana&nbsp;</em>plant. Pollen grains are labeled with fluorescent markers and sit at the top of the structure. Fluorescently tagged pollen tubes penetrate the plant&rsquo;s ovary where the ovules (small, curved structures) are located.

Why Do We Feel Butterflies in the Stomach?

These fluttering sensations are the brain’s reaction to certain emotions, which can be amplified or soothed by the gut’s own “bugs".
