How long does memory last? For shape memory alloys, the longer the better

Known to many as muscle wire or memory metal, shape memory alloys are materials that can be bent or deformed, and then return to their original shape when heat is applied. While people are most familiar with the material in "unbreakable" eye-glass frames, these alloys are also used as vibration dampers, actuators, and sensors in high technology applications like the aerospace and automotive indust

Cell-Bacteria Mergers Offer Clues to How Organelles Evolved

There are few relationships in nature more intimate than those between cells and the symbiotic bacteria, or endosymbionts, that live inside them. In these partnerships, a host cell typically provides protection to its endosymbiont and gives it a way to propagate, while the endosymbiont provides key nutrients to the host. It’s a deeply cooperative arrangement, in which the genomes of the host and

They include increased risk of poor cognitive development, impaired growth and early death. Ironically, our latest research found that many coastal countries where hidden hunger is rife, have plenty of

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.

Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.

Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
