Titan's seas are sand

Scientists discovered massive sand dunes on Saturn's moon Titan, formed by tidal winds and unique atmospheric conditions. The dunes, similar to those in Namibian Deserts, suggest that Titan's atmosphere can create surface winds powerful enough to sculpt sand.

New strategy developed to combat West Nile Virus

Researchers identify key factors that contribute to the amplification and transmission of West Nile Virus, including drought-induced conditions and specific mosquito species. By understanding these local conditions, control strategies can be devised to prevent the spread of the disease.

Embryos exposed in 3-D

A new method called microCT-based virtual histology allows scientists to quickly examine large numbers of mouse embryos with different genetic mutations or damage from toxic chemicals. This enables them to determine the normal function of many genes faster than existing methods, improving drug safety and efficacy.

Landing on Titan: The new movies

The new movies released by NASA's Cassini mission provide a realistic experience of the Titan landing. The images taken by Huygens' Descent Imager/Spectral Radiometer (DISR) during its plunge into Titan's atmosphere have been converted into movie format, showcasing the probe's descent and the changes it observed in the environment.

Expanding waistlines triggered by your genes

Researchers at U-M's Life Sciences Institute discovered that the MT1-MMP gene regulates fat cell size and metabolic gene expression. In three-dimensional environments, the gene plays a critical role in adipocyte development, potentially leading to novel therapeutics for obesity prevention.

In 3D, early fat development first requires 'remodeling'

In the absence of MT1-MMP, preadipocytes fail to break through extracellular matrix, disrupting fat cell development. However, MT1-MMP is essential for remodeling the surrounding matrix to facilitate normal fat formation. The enzyme may also regulate collagen in white adipose tissue and act as a protein-degrading rheostat.
