The House We Live In — Real Life
Real Life is a magazine about living with technology. The emphasis is more on living. We publish one piece a day—essays, features, uncategorizable—four or five days a week. We launched with funding from Snapchat, but we operate with editorial independence and without ads.

The Magic of Education - Econlib
If professors don’t teach a lot of job skills, don’t teach their students how to think, and don’t instill constructive work habits, why do employers so heavily reward educational success?  The best answer comes straight out of the ivory tower itself.  It’s called the signaling model of education – the subject of my book in progress, The Case Against Education. 

According to the signaling model, employers reward educational success because of what it shows (“signals”) about the student.  Good students tend to be smart, hard-working, and conformist – three crucial traits for almost any job.  When a student excels in school, then, employers correctly infer that he’s likely to be a good worker.  What precisely did he study?  What did he learn how to do?  Mere details.  As long as you were a good student, employers surmise that you’ll quickly learn what you need to know on the job."

JAGUAR LAND ROVER LIGHTS UP THE ROAD AHEAD FOR SELF-DRIVING VEHICLES OF THE FUTURE
Interesting HCI work on showing self driving car intentions. Japanese makers seem to working more towards expressive eyes as the signal system though.

Interdependence between EGFR and Phosphatases Spatially Established by Vesicular Dynamics Generates a Growth Factor Sensing and Responding Network: Cell Systems
Very complex but interesting use of labeled EGF, EGFR and PTB domain to track EGFR-p during stimulation. Basic idea that EGFR signaling remains on until EGFR is brought to PTPN2 on the ER, and then is dephosphorylated and that monomer phosphorylation is minimized by several other PTPRs (PTPRG and PTPRJ) with an added twist of the role of oxygen radicals to alter PTP activity

Democracy as an information system — Crooked Timber
Democracy is an information system.

That’s the starting place of our new paper: “Common-Knowledge Attacks on Democracy.” In it, we look at democracy through the lens of information security, trying to understand the current waves of Internet disinformation attacks. Specifically, we wanted to explain why the same disinformation campaigns that act as a stabilizing influence in Russia are destabilizing in the United States.

The answer revolves around the different ways autocracies and democracies work as information systems. We start by differentiating between two types of knowledge that societies use in their political systems. The first is common political knowledge, which is the body of information that people in a society broadly agree on. People agree on who the rulers are and what their claim to legitimacy is. People agree broadly on how their government works, even if they don’t like it. In a democracy, people agree about how elections work: how districts are created and defined, how candidates are chosen, and that their votes count­—even if only roughly and imperfectly.

Signaling, Shame, and Silence in Social Learning
We examine how a social stigma of seeking information can inhibit learning. Consider a Seeker of uncertain ability who can learn about a task from an Advisor. If higher-ability Seekers need information less, then a Seeker concerned about reputation may refrain from asking to avoid signaling low ability. Separately, low-ability individuals may feel inhibited even if their ability is known and there is nothing to signal, an effect we term shame. Signaling and shame constitute an overall stigma of seeking information. We distinguish between the constituent parts of stigma in a simple model and then perform an experiment with treatments designed to detect both effects.

Lessons in Signaling and Tumorigenesis from Polyomavirus Middle T Antigen | Microbiology and Molecular Biology Reviews
Nice summary of PyMT signaling

"The small DNA tumor viruses have provided a very long-lived source of insights into many aspects of the life cycle of eukaryotic cells. In recent years, the emphasis has been on cancer-related signaling. Here we review murine polyomavirus middle T antigen, its mechanisms, and its downstream pathways of transformation. We concentrate on the MMTV-PyMT transgenic mouse, one of the most studied models of breast cancer, which permits the examination of in situ tumor progression from hyperplasia to metastasis
