Video tracking for high-throughput screening of plant resistance to thrips

Posted by Olga Krips on Sep 26, 2016

Unless you grow plants commercially, you may very well not know what a thrips is. It is a tiny insect that can have a not-so-tiny effect on plants. Thrips pierce plant leaves and flowers and suck out their contents. And, not less important, many plant viruses are known to be transmitted by thrips [1]. Needless to say, a lot of research is currently carried out on how to get rid of these creatures.

What emotions does an author inject into a book?

Posted by Annelies Verkerk on Sep 20, 2016

“A book is beauty. A book is a shelf, a wall, a home.” states Simon Jenkins, the Guardian. He informs us that the digital book has had its peak. Paper books are instead just what he says: a shelf, a wall, a home. But how do you shove your shelf, wall, or home into a suitcase and fly off to Florida? I’d rather put my Kindle in my handbag and have all the books I’d ever want to read with me.

High-throughput screening of plant lines for resistance to pest insects

Posted by Olga Krips on Sep 16, 2016

One of the great things about working for Noldus IT is its involvement in scientific research projects. Because the tools that we offer are used in scientific research, it is logical that we also participate in projects for which such tools are developed.

The power of rejection (in fruit flies)

Posted by G. Smit, MSc & A.H. Macbeth, PhD on Sep 1, 2016

In a previous post we talked about fruit flies and their amazing sense of smell. This includes the ability to navigate to a food source, as well as search out a preferred mate. However, there are other areas in which their olfactory systems come into play. This includes courting behavior (did you know the male does all the work?) and obesity. Yes - obesity can be studied in fruit flies.

The use of video tracking in a HaXha test

Posted by G. Smit on Aug 25, 2016

When you get used to something, after a while you might not notice it anymore. It’s called habituation. When you are repeatedly presented with the same stimulus you might cease to respond to it altogether.

How fruit flies find your food (and mates!)

Posted by G. Smit, MSc & A.H. Macbeth, PhD on Aug 18, 2016

Those tiny flies that take over your garbage cans during the summer? They are called fruit flies (or, Drosophila, their scientific name) for a reason! They have a fantastic sense of smell, but they also have a lot more in common with us that you might think. With 75% genetic commonality with humans, particularly the genes that cause human disease, these tiny creatures are a popular animal model for researchers.

Video-recording children with ASD in-home

Posted by Jacqueline Martinali on Aug 8, 2016

Nowadays we often come across signs or printed versions of funny, motivational, and inspirational quotes about our homes. You’ll probably confirm this for yourself: we’ve all seen  a postcard, a doormat, or a picture in a magazine with sentences like: ‘Home is where the heart is’, ‘Home is where you can be yourself’ or ‘Home sweet home’. A funny one I like is ‘Home is where your Wi-Fi connects automatically’. We also read listings which convince us that ‘in this house we are real, we make mistakes, we say I’m sorry, we have fun, we forgive, we love’ and so on.

Implementing Tailored Activity Programs

Posted by Julie Harrison on Aug 2, 2016

Sometimes pharmacological strategies can hurt more than they help. This is why non-pharmacological strategies are meant to be used as the first-line in the treatment of patients, but it can be difficult to tell which strategies should be used with dementia patients in hospitals.

3 reasons to join us at the AHFE meeting in Florida

Posted by Annelies Verkerk on Jul 21, 2016

Next week the 7th International Conference on Applied Human Factors and Ergonomics will kick off. It is always great to use the summer season to meet other researchers, walk along the poster boards, discuss and exchange ideas about new applications, and view the latest tools and solutions for research. AHFE facilitates it all: keynote presentation, parallel sessions, demonstration and poster sessions, tutorials, exhibitions, and meetings of special interest groups.
