Dogs have at least a rudimentary neural representation of meaning for words they have been taught, differentiating words they have heard before from those they have not, research suggests.

Plants are capable of registering essential information about environmental conditions. Scientists are finding out how they delete this memory after they produced seeds.

Scientists estimate that our oceans contain approximately 10^8 (one hundred million) viruses per milliliter. Yet, very little is known about the interaction with non-host marine animals

According to scientists, humans and their animals now greatly outnumber the number of wild animals roaming the Earth. This ratio will be reflected in future fossil records. Our growing numbers, combined with our technological advances, have led to our impact on the natural word now being equal or even exceeding those of natural processes.

An international research team has mapped the phylogenetic family tree of stick insects and leaf insects.

What is the reason that agriculture yields less in African countries than in other places?

Bees are pretty good at maths – as far as insects go, at least. We already know, for example, that they can count up to four and even understand the concept of zero. But in a new study, published today in the Journal of Experimental Biology, we show honeybees can also understand numbers higher than four – as long as we provide feedback for both correct and incorrect responses as they learn.
