Like butterflies, different species of fruit flies decorate their wings with a great diversity of spots and patterns. Digging deep into a single gene that produce pigmentation in the flies, a group led by UW-Madison biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.
Maori stones hold magnetic clues: Scientists are studying the Earth's magnetic field using the stones that line Maori steam ovens. The cooking process generates so much heat that the magnetic minerals in these stones will realign themselves with the current field direction.
So, a fruit fly walks into a bar... Galit Shohat-Ophir and her colleagues discovered that the more a male fruit fly’s sexual advances are rejected, the more likely the fly will turn to alcohol as a consolation.
