The world’s attention is now on Proxima Centauri b, a possibly Earth-like planet about 4.22 light-years away. It’s in its star’s habitable zone — but could it in fact be habitable? If so, the planet evolved very different than Earth, say researchers at the 91̽»¨-based Virtual Planetary Laboratory.

Death and mourning were largely considered private matters in the 20th century, with the public remembrances common in previous eras replaced by intimate gatherings behind closed doors in funeral parlors and family homes. But social media is redefining how people grieve, and Twitter in particular — with its ephemeral mix of rapid-fire broadcast and personal expression — is widening the conversation around death and mourning, two 91̽»¨ sociologists say. In a paper presented Aug. 20 at the annual…

“Interscatter” communication developed by 91̽»¨engineers allows power-limited devices such as brain implants, contact lenses, credit cards and smaller wearable electronics to talk to everyday devices such as smartphones and watches.

How much liability do website owners and other online service providers have for content posted by other people? If someone posts content on your website that is defamatory, constitutes hate speech, disseminates child pornography or invades someone’s privacy, are you liable? The answers to such questions can be murky in developing countries. And as internet use expands around the globe, so does the potential liability for the owners of websites, search engines, social media sites and other online platforms, who…

What are the policies of global rising powers regarding the use of orbital and outer space, and what are the implications of those policies for international cooperation? A capstone event for junior fellows of the Jackson School’s Space Security Initiative explored such questions in a recently with space industry, media and government representatives also on hand.

A team led by 91̽»¨ engineers has developed a new tool that could aid in the quest for better batteries and fuel cells. Although battery technology has come a long way since Alessandro Volta first stacked metal discs in a “voltaic pile†to generate electricity, major improvements are still needed to meet the energy challenges of the future, such as powering electric cars and storing renewable energy cheaply and efficiently. The key likely lies in the nanoscale, said…

Electrical energy fuels our modern lives, from the computer screen that keeps us up after sunset to the coffee maker that greets us at sunrise. But the electricity underlying our 21st century world, by and large, is generated at a cost — through the unsustainable expenditure of fossil fuels. For decades this demand for cheap, fast and non-renewable electricity has promoted pollution and global warming. The key to reversing this downward spiral is deleting the “non” in “non-renewable electricity.” In…

The 91̽»¨ has joined NextFlex, a consortium of 30 academic institutions and industrial partners to develop the next generation of flexible electronic devices. As a founding member of this alliance, the 91̽»¨will seek local and regional partners in the electronics and manufacturing industries to develop and produce flexible electronics for applications from medicine to transportation. Flexible electronics are inherently thin and designed to be bent, rolled, folded or incorporated into new technologies or products in ways that…

In the maelstrom of information, opinion and conjecture that is Twitter, the voice of truth and reason does occasionally prevail, according to a new study from 91̽»¨researchers. Tweets from “official accounts” — the government agencies, emergency responders, media or companies at the center of a fast-moving story — can slow the spread of rumors on Twitter and correct misinformation that’s taken on a life of its own.

With apps and activity trackers measuring every step people take, morsel they eat, and each symptom or pain, patients commonly arrive at doctor’s offices armed with self-tracked data. Yet health care providers lack the capacity or tools to review five years of Fitbit logs or instantaneously interpret data patients have been collecting about themselves, according to new 91̽»¨research.
