Protecting quantum computing networks against hacking threats
As we saw during the 2016 US election, protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science. Now consider the complex world of quantum computing, where bits of information can simultaneously hold multiple states beyond zero and one, and the potential threats become even trickier to tackle. Even so, researchers at the University of Ottawa have unc


Study finds mutual reinforcement of phenotypic diversity and cooperation
A new model exploring how evolutionary dynamics work in natural selection has found that phenotypic diversity, or an organism's observable traits, co-evolves with contingent cooperation when organisms with like traits work together to protect themselves from outsiders, according to a Dartmouth-led study published in PLOS Computational Biology. The study also finds that diversity helps prevent the


Why a concussion may raise Alzheimer’s risk for some people
Researchers have known for more than a decade that people who experience a severe or moderate traumatic brain injury are at greater risk of getting Alzheimer’s later on, but far less is known about how “mild” traumatic brain injuries, or concussions, affect brain health over time, even though they make up more than 70 percent of all head injuries. “People tend to ignore concussion and just shake

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.
