How you can efficiently screen for plant resistance to aphids

Aphids are small insects that pierce plant leaves and suck out their contents. Although they inflict limited physical destruction to the plant, aphids commonly infect plants with viruses, which can destroy complete harvests.
zinc-deficiency-depression

Zinc deficiency, depression and electrical signals in the brain

Depression has a dramatic effect on quality of life because it results in a persistent low mood that is accompanied by a low self-esteem and a loss of interest in things that give pleasure.
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.
high-throughput-method-natural-behavior-mice

A high-throughput method to screen natural behavior of mice

Traditional standard tests with rats or mice are carried out immediately after human interference. Therefore, the behavior of the animals may not be natural and spontaneous.
anxiety-ancient-crayfish

Anxiety is ancient – how crayfish resemble vertebrates

Fear is something we all know. It changes our behavior: we freeze, try to escape, or respond with aggression. Fear can also cause anxiety, which is a more complex phenomenon.
optimizing-pollination

Insect damage on leaves changes the reproductive strategy of plants

We all know that the majority of plant species depends on pollinators, like bees and syrphid flies, for reproduction. What most of us do not know is that this process is far more complex than it looks at first sight.

Measuring behavioral effects of laboratory rearing on starlings

Rearing animals specifically for behavioral research is a very common practice. However, the results from behavioral studies with laboratory animals should be interpreted with care.

Making the impossible possible – Tracking under water in the dark

European eels (Anguilla anguilla) have a life cycle in which both larvae and adults travel incredible distances. The eggs hatch in the Sargasso Sea near North America and the larvae swim all the way to Europe.

Smelly feet and heat – how malaria mosquitoes find their hosts

It seems that mosquitoes use human body odor to locate suitable hosts, and different people smell differently to mosquitoes.
