Kenneth Winneg and Kathleen Hall Jamieson, American Behavioral Scientist, 2017: In this study, University of Pennsylvania researchers look at whether people gained knowledge about policy issues and changed their minds about the candidates after watching televised presidential debates in 2016. What the two scholars learned: While debate watchers gained knowledge about policies, their assessment of candidates’ qualifications did not change. Neither did their opinions of whether individual candidates, if elected, would threaten the well-being of the nation.   more »

"At a reception some years ago, a college student asked if I could help her with an assignment. She had one question and hoped to compose a paper by asking diverse people to respond. What, she asked, did I think was the largest problem for the 21st century. My mind raced passed privacy concerns in the electronic age, terrorist threats, deadly weapons, fierce partisan divisions in our legislatures and polity. I thought of Thurgood Marshall’s praise of the evolution of our Constitution’s opening words, 'We, the people,' to embrace once excluded, ignored, or undervalued people — people held in human bondage, Native Americans, women, even men who owned no real property. I thought next of our nation’s motto: E Pluribus Unum, of many, one. The challenge is to make or keep our communities places where we can tolerate, even celebrate, our differences, while pulling together for the common good. 'Of many, one' is the main aspiration, I believe; it is my hope for our country and world." more »

Altogether, the sector holds about $108 trillion in assets and faces a variety of cybersecurity-related risks. Key risks include (1) an increase in access to financial data through information technology service providers and supply chain partners; (2) a growth in sophistication of malware — software meant to do harm — and (3) an increase in interconnectivity via networks, the cloud, and mobile applications. Cyberattacks that exploit risks can occur against either public or private components of the sector. For example, in February 2016, hackers were able to install malware on the Bangladesh Central Bank's system through a service provider, which then directed the Federal Reserve Bank of New York to transfer money to accounts in other Asian countries. This attack resulted in the theft of approximately $81 million. more »

If you happen to dig up an ancient ceramic cooking pot, don’t clean it. Chances are, it contains the culinary secrets of the past. A research team led by UC Berkeley archaeologists has discovered that unglazed ceramic cookware can retain the residue of not just the last supper cooked, but, potentially, earlier dishes cooked across a pot’s lifetime, opening a window onto the past. The findings, reported in the journal Scientific Reports, suggest that gastronomic practices going back millennia — say, to cook Aztec turkey, hominy pozole or the bean stew likely served at the Last Supper — can be reconstructed by analyzing the chemical compounds adhering to and absorbed by the earthenware in which they were prepared.  more »
