Math models predict mysterious monarch navigation
Researchers have come up with a series of equations to predict how monarchs use their eyes and antennae to figure out how to get to Mexico.

Gene found that controls beak size in Darwin’s finches
A beak-size gene helped determine whether Darwin’s finches survived a drought.

Just adding pollinators could boost small-farm yields
Adding pollinators could start closing gap in yields for small farms.
- Genetics
GMOs haven’t delivered on their promises — or risks
Genetically modified foods have been studied extensively and are abundant on supermarket shelves, but they haven’t managed to end world hunger yet.

Root fungi make or break monarchs’ chances against parasite
Fungi that live amid the roots of milkweed plants change the chemicals produced in the plant’s leaves, which can either aid or hinder a monarch butterfly’s ability to fight off parasites.
- Animals
Biologists aflutter over just where monarchs are declining
Citizen science data fuel debate over whether weed control ruined monarch habitat and whether the butterflies are failing to reach their Mexican winter refuge.

Caterpillar treats and tricks ants by oozing spiked juice
Caterpillars ooze droplets that lure ants away from colony duties to instead lick and defend their drug source, new lab tests suggest.

Nighttime light pollution sabotages sex pheromones of moths
Artificial lighting at night can trick female moths into releasing skimpy, odd-smelling sex pheromones.

A protein battle underlies the beauty of orchids
The petal-and-lip shape that draws pollinators to orchids results from a competition between two protein complexes, a new study finds.
