ny blodtest forudsiger hjertekarproblemer – ny test
New blood test may predict cardiovascular events in patients with or without coronary artery disease
A new type of blood test may help physicians identify which patients with and without evidence of coronary blockages are at risk for heart attacks and strokes. Even individuals with normal levels of low-density lipoprotein (LDL), known as the so-called “bad” cholesterol, but still at risk, seem to be identified.

Roundup-rotteforsøg – kritiseret forsøg genåbnet
Forskere genåbner kritiseret rottestudie
Da en rapport om effekterne af Roundup på rotter blev trukket tilbage fra et videnskabeligt tidsskrift i 2013, regnede de fleste med, at rotterne var lagt i graven. Men de var kun i fryseren, og nu er de fremme igen.

//innovation og hvad der stimulerer den
What is innovation, and how can we awaken its dormant traits and cultivate them?
While education may not be able to create innovative traits in individuals, education may improve the ability of individuals to utilize the traits they already possess. To that end, the authors begin by defining innovation and identifying the characteristics, traits, and thought processes of innovative individuals or groups of individuals and the environments that they exist in. The ultimate goal

Frst exact model for diffusion in magnesium alloys
In order to develop new materials, material engineers need to be able to predict how fast impurity atoms diffuse, or spread, in a crystal over a range of temperatures. Using new computational techniques, researchers have constructed the first exact model for diffusion in magnesium alloys. While magnesium is the lightest structural metal, this new model could mean big things for material engineers,
