Altrichthys alelia (Alelia’s damselfish) is a new species of damselfish discovered in the Philippines. Unlike most coral reef fish, in this species the parents care for their young.

A new study from Lund University in Sweden shows that non-migratory birds also are able to use a built-in compass to orient themselves using the Earth’s magnetic field. The researchers behind the current study have received help from

Now, the same research group has confirmed that those striking changes in

“The strength of the fiber is significantly better than any human-made, silk-based material to our knowledge, and on the same level as what can be found in nature from spiders,” says Daniel Söderberg, a researcher with the Wallenberg Wood Science Center at KTH.

Duke researchers have discovered that gut microbes can alter the action of their host organism’s genes. Mouse intestinal cells are outlined in red, with the cell nuclei stained blue and a protein called transcription factor Hnf4a stained green within the nuclei. Microbes were found to suppress Hnf4a in both mice and fish in a way

The moms were even able to nurse their young. Credit: Image courtesy of Northwestern University The brave new world of 3-D printed organs now includes

A new study from the University of Turku, Finland, shows that removing the largest individuals from the

This research adds to our understanding of how bees — insects with a brain no bigger than a pinhead — can perform complex tasks.

The researchers used artificial

Researchers transplanted a transparent artificial forewing, or elytron, onto a Coccinella septempunctata seven-spotted ladybug (left) to observe its wing-folding process in detail. The artificial wing is made of ultraviolet light-cured resin and constructed from a silicon impression of the elytron’s undersurface.
