Researchers at Washington University School of Medicine in St. Louis are transplanting jellyfish genes into mice to watch how neural connections change in the brains of entire living animals. The development represents the merging of several technologies and enable researchers to watch changes inside living animals during normal development and during disease progression in a relatively non-invasive way.
"This work represents a new approach to studying the biology of whole, living animals," says Jeff W. Lichtman, M.D., Ph.D., professor of anatomy and neurobiology. "I believe these methods will transform not only neurobiology, but also immunology and studies of organs such as the kidney, liver, and lung."
Lichtman presented the work at the 40th annual New Horizons in Science Briefing, sponsored by the Council for the Advancement of Science Writing, held Oct. 27-30 at Washington University in St. Louis.

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is...
At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
