A drug called enoxacin, originally developed to treat bacterial infections, has proved capable of boosting the metabolism and attenuating the weight gain induced by a fatty diet in tests with mice.

This confocal image of a mouse brain tissue shows the astrocytes (red) and neurons (green).

Researchers have identified a gene that plays an important role in fertility across multiple species. Pictured is a normal fruit fly ovary (left) and a fruit fly ovary with this gene dialed down (right).

This image shows transplanted pancreatic islet cells in which insulin is shown in red, the cell nucleus in blue, and the blood vessels in aqua.

This is an electron micrograph of the fly foot. The adhesive spatula-shaped setae (light-blue structures) allow the fly to attach itself to objects.

Inside the ovary of the fruit fly, sex cells divide, multiply and grow to become mature eggs. A new study shows that this normal physiological process causes female fruit flies to develop a preference for sugar.

Lung cancer cells (green) grow within healthy lung tissue (red) in the lung cancer chip, used to model and study how tumors grow.

These images show glial cells of the optic chiasm in the adult fly brain that have accumulated extra genome copies.

In the study during which this image was taken, nematode worms were engineered to express fusogens in their neurons. These nerve cells fused together, causing behavioral impairments.
