What would happen if you pitted Bart Simpson against his father Homer in a simple fitness test? You guessed it, Bart would come out of the test still standing, while Homer would be struggling for breath with his heart rate going through the roof. Young Scientist magazine, published by Institute of Physics Educational Publishing, is running a national investigation into school children’s activity levels. If Bart took part in this, he would have no problems. He obviously hasn’t been taking notes from his father, as Homer would not do nearly as well.
The Institute of Physics did some research into the Simpsons’ lifestyle. By watching videos of the cartoon and recording how much activity Bart and Homer do in the episodes, as well as how much they eat, Institute staff then worked out how fit and healthy they are.
The Institute found that obese Homer eats an average of about 130 grams of fat per day – most of it saturated, often coming from junk food – much more than his recommended 83 grams. On the other hand, Bart eats the right amount of fat per day: about 60 grams, although this includes rather more saturated fats than is ideal. Bart also does much more exercise than Homer, who drives to work, spends most of his day sitting (and eating donuts!) and watches television in the evenings. Bart’s frequent walking, cycling and skateboarding mean that he’s actually quite active, even though he sits in school for most of the day and does watch cartoons in the evening. He’s also growing which uses up a lot of calories.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
