Discovery mirrors expectations for genetic complexity of common diseases
Johns Hopkins scientists studying a rare inherited syndrome marked by eye and kidney problems, learning disabilities and obesity have discovered a genetic mutation that makes the syndrome more severe but that alone doesnt cause it. Their report appears in the advance online edition of Nature (Dec. 4).
The new discovery about Bardet-Beidl syndrome (BBS) came from a panoply of studies -- starting with comparative genomics and experiments with yeast, and moving to experiments with zebrafish and genetic analysis of families with the syndrome -- and mirrors what experts expect for the genetically complex common diseases that kill most Americans, like diabetes, heart disease and cancer.

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...
