Exposure to Diverse Political Views in Contemporary Media Environments
SSRN Electronic JournalExploring the nexus between digital media and citizens’ exposure to diverse political views is imperative for understanding contemporary democratic engagement. This study builds upon Mutz and Martin’s (2001) seminal research, integrating digital communication channels previously unexamined. Our findings suggest that the interpersonal character of media

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Influence of Selective Exposure to Viewing Contents Diversity
, 2018 Personalization, including both self-selected and pre-selected, is inevitable when tremendous amounts of media content are available. Personalization, which is believed to cause people to consume fewer diverse contents, can lead to fragmentation and polarization in society.

Exposure diversity as a design principle for recommender systems [PDF]
Information, Communication & Society, 2016 Personalized recommendations in search engines, social media and also in more traditional media increasingly raise concerns over potentially negative consequences for diversity and the quality of public discourse. The algorithmic filtering and adaption of online content to personal preferences and interests is often associated with a decrease in the ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Structure, function and diversity of the healthy human microbiome [PDF]
, 2012 Studies of the human microbiome have revealed that even healthy individuals differ remarkably in the microbes that occupy habitats such as the gut, skin and vagina. Much of this diversity remains unexplained, although diet, environment, host genetics and
