While cats have evolved without the ability to taste sweetness, they have retained at least seven receptors that register bitter tastes. This may explain why they're such picky eaters.
A new giant tortoise species, named the Eastern Santa Cruz Tortoise, was recently found in Galapagos. Now studies are helping researchers target conservation efforts that will help protect the animals and their natural habitats.
A detailed genetic analysis suggests that Central Asia was home to the world’s first domesticated dog.
While the social roles some insects inhabit are set in stone, dinosaur ants and red paper wasps are far more flexible – and able to adjust their behaviors for varying responsibilities.
After sequencing a genome of an ancient African male skull, researchers revealed more about the early humans' migration and introduction of farming in East Africa.
In a new study, students shed light on how sea stars respond to a deadly disease that caused a major die-off three years ago. This could help conservationists better protect starfish populations.
Elephants have a strong internal defense system that ultimately enhances the animal's resistance to cancer, a new study revealed. Scientists could ultimately use this to better prevent cancer in humans.
Embedded in the genetic code of several snake species was DNA that generally controls the development and growth of limbs in other animals.
CRISPR, a gene-editing system, could have serious consequences if rapidly spreading genes end up in the wrong species.
Since plants have been bred without their natural defenses, researchers are making a series of suggestions on how to better protect them and enhance agricultural sustainability.
Black rice, also known as forbidden rice, was once reserved for the Emperor. Now, it is widely popular for having high antioxidants. A new study sheds light on how the grains got their dark color.
Mice rely on scent to recognize relatives they have never even met before. This is important when choosing the right nesting partners and to ensure that the right genes are passed on to offspring.
A new study sheds light on the evolution of tooth enamel tissue. It turns out that the enamel protecting human teeth originated in the scales of ancient fish.
Wild and domesticated horses began evolving differently from one another some 45,000 years ago, but a recent study has revealed their genetics ties and is providing a greater understanding of both past and present populations.
Microbiologists recently discovered a way to combat worldwide ocean dead zones that are attributed to nitrogen-based fertilizers. Naturally occurring bacteria called rhizobia could replace nitrogen in fertilizer once more is learned about one of its genes called HrrP. Reduced nitrogen runoff would translate into fewer ocean dead zones.
