Bigger is not always better: hypothesis testing in sexual evolution

Sexual selection can lead to fascinating phenomena. We are all familiar with the fabulous color display of male peacocks to attract females. Less well known, but definitely not less interesting, are stalk-eyed flies.

A new approach in the battle against malaria

Bed nets treated with insecticide (ITNs) greatly decrease malaria illness and mortality. ITNs can decrease infant mortality from all causes by more than 20%.

Ferrets are the ideal animal model to assess influenza virus infection and pathogenicity as they display similar clinical symptoms to humans such as sneezing, fever and lethargy.
aphid-predators

Ladybugs and lacewings do not spy on their prey’s alarm pheromone

Leaf sucking creatures like plant aphids are common and can cause considerable damage to plants. Therefore, quite a lot of effort is made to control these tiny creatures.
sniffing-indicator-tastiness

Picky cats and tasty food – sniffing is an indicator for tastiness

Cats can be extremely picky when it comes to food. If the cat doesn’t like it, it will refuse to eat. Reason enough for the pet food industry to try to find out what cats really like.

Walking the ladder: testing the cellular source of motor functioning in mice

The cerebellum, our “little brain”, is all about motor control; more specifically, it’s about coordination, precision, and timing.

Mixing sows: aggression and stress of group housing on first-time sow mother

In this experiment, Ison and colleagues looked at the social interaction when a mixed group of primiparous and older, unfamiliar sows were placed in group housing together.
