Researchers at the University of Alberta have discovered that chickens raised for meat can choose whether or not theyll funnel the nutrients they eat towards themselves or their eggs.
That phenomenon of reproductive attitude is a headache for producers who must figure out how to deal with less productive hens that "partition" nutrients needed for egg production into their own bodies. "They like to be a little bit more selfish with their nutrients, and continue growing," said Dr. Martin Zuidhof, an Alberta Agriculture researcher who is collaborating with the University of Alberta to solve the dilemma.
"Some of the broiler breeders (parents of chickens raised for meat) are happy to shift their nutrients from the growth of their bodies to egg production, but some of them dont do it very willingly. It is not a conscious thing the bird does, but it does express a tendency of that bird to either be generous or to be selfish with its nutrients."

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
