I set off to be the first person to cycle alongside the butterflies to raise awareness of their alarming decline

As many commercial operators and homeowners are shifting to LEDs, which tend to fall somewhere in the blue-white spectrum, the new results may have important implications beyond tropical rainforests.

Using Amber-Filtered Bulbs Instead of White Light Attracts Fewer Bugs

In a tropical rainforest study, 60 percent fewer insects visited traps illuminated in a golden glow. Researchers say the results may be widely applicable

A tiny, aphid-like whitefly sitting on a leaf.

This Insect Has Plant DNA in Its Genome

Whiteflies have a gene only found in plants that appears to allow the tiny insects to withstand plants’ chemical defenses

After five weeks of development, a human brain organoid (left) is roughly twice the size of those from a chimpanzee (top right) and a gorilla (bottom right).

Experiments Find Gene Key to the Human Brain's Large Size

The single gene identified by the study may be what makes human brains three times larger than our closest great ape relatives at birth

All modern dogs are descended from a wolf species that when extinct around 15,000 years ago. Grey wolves, pictured here fighting for food with now extinct dire wolves (red), are dogs’ closest living relative.
