Creating ideal silicone molds faster and cheaper  

The method of fabricating objects via silicone molding has a long tradition. Until now, however, creating molds for casting complex objects required a lot of experience and still involved manual work, which made the process expensive and slow. Researchers have now developed a tool that not only automatically finds the best design of the molds but also delivers templates for so-called 'metamolds': Rigid molds that are 3D-printed and are used to fabricate the silicone molds.

STAT3 can be a therapeutic target for chronic active EBV infection, a fatal disorder  

Chronic active Epstein-Barr virus infection (CAEBV) is an inflammatory disorder with potential for tumor development. Here, unusual phosphorylation was observed on STAT3 in EBV-infected T- or NK-cells from patients with CAEBV. Researchers found that ruxolitinib, a drug that is currently used for treatment of myelofibrosis and polycythemia vera, could suppress the survival of these EBV-infected cells in a dose-dependent manner, and that STAT3 could be an important new target for treatment of CAEB

Massive monumental cemetery built by Eastern Africa's earliest herders discovered in Kenya  

An international team has found the earliest and largest monumental cemetery in eastern Africa. The Lothagam North Pillar Site was built 5,000 years ago by early pastoralists living around Lake Turkana, Kenya. This group is believed to have had an egalitarian society, without a stratified social hierarchy. Thus their construction of such a large public project contradicts long-standing narratives that a stratified social structure is necessary to enable the construction of large public monuments

Chemical engineers uncover ways to pattern solid surfaces to enhance how water interacts with them  

The dynamics of water near solid surfaces play a critical role in numerous technologies, including water filtration and purification, chromatography and catalysis. One well-known way to influence those dynamics, which in turn affects how water "wets" a surface, is to modify the surface hydrophobicity, or the extent to which the surface repels water. Such modifications can be achieved by altering the average coverage, or surface density, of hydrophobic chemical groups on the interface.

How an herbivore hijacks a nutrient uptake strategy of its host plant  

Maize plants release secondary metabolites into the soil that bind to iron and thereby facilitate its uptake by the plant. The Western corn rootworm (Diabrotica virgifera), the economically most important maize pest worldwide, is attracted by these complexes, extracts the bound iron from the maize plant and uses it for its own nutrition. With these insights, researchers provide a new explanation for the extraordinary success of the Western corn rootworm as a global maize pest.
