How ants find their way
Insects use a wide range of tools for orientation, including visual memory, smell, and counting steps. The tricky question is how they combine and compute different kinds of inputs, and whether their methods can help us understand more complex brains or create artificial ones. Michael Gross investigates. Bottom of the article, you will be able to find a simulator link for How ants find their way.

Cyborg Cockroaches With Solar-Powered Backpacks Could Deploy in Disaster Zones
The first thing to know about the Madagascar hissing cockroach, a black-and-brown invertebrate about as long as your forefinger, is that it lives up to its name. When it feels threatened, it squeaks out a hiss by quickly passing air through holes in its back. The result is something resembling the rattle of a snake's tail. Weird but cool.

Monarch butterfly populations are thriving in North America
For years, scientists have warned that monarch butterflies are dying off in droves because of diminishing winter colonies. But new research from the University of Georgia shows that the summer population of monarchs has remained relatively stable over the past 25 years. Published in Global Change Biology, the study suggests that population growth during the summer compensates for butterfly losses due to migration, winter weather and changing environmental factors.

A gut-invading parasite is plaguing monarch butterflies in Calif.
After rebounding from the brink of extinction, monarch butterflies are once again in crisis. The California Department of Fish and Wildlife (CDFW) says that from 2021-2022, California's western monarch population plummeted to less than 2,000 and flew back up to 200,000 as of this year – but researchers have discovered a new threat to the iconic migratory butterfly species.

Monarch Butterfly Count Up 35% in WWF-Mexico Survey
After many years of plummeting populations of migrating monarch butterflies, a WWF-Mexico survey brings good news: during the 2021-2022 overwintering period, the monarch butterfly presence observed in the forests of Mexico was 35% higher than the previous year. While the butterflies are still vulnerable and require more conservation efforts, the survey gives some hope for recovery.
