ShakeAlert's big test in Santa Rosa earthquake

To address the food insecurity problem among its low-income students, Columbia University launched Swipes, a meal sharing app in which students with a surplus of “meal swipes” could donate them to students in need. But when that app struggled to function and roll out properly, Columbia looked downtown to New York University, where student Jon Chin launched a similarly purposed but more effectively designed app, Share Meals. So far, the app has enabled over a thousand meal donations, and is hoping to work with Columbia to share its code and expand its donor services.

Despite advancements in technology in most sectors of life leading to an increase to access of information about practically anything, little is still known about the ocean and its behavioral patterns. Liquid Robotics – a Silicon Valley-based company – is trying to change that. Engineers here have created the "Wave Glider," which essentially acts as a router within the ocean powered by wave energy and solar panels. This invention can transmit data on tectonic activity that has the potential to predict tsunamis.

Though homelessness is an entrenched and complex problem, small solutions can make a difference in the daily life of homeless individuals. Lockers for overnight cell phone storage in a homeless shelter in Chicago are significant: people can wake up with a sense of security, knowing their phones will be available to help find jobs or stay in touch with loved ones. This is part of the Chicago Youth Storage Initiative, which as since funded 755 storage unites at homeless shelters across Chicago.

LGBTQ asylum seekers face a unique set of problems coming to the United States, often from places where gender expression and sexuality are strictly regulated. Four organizations across the US, Mexico, and Canada are filling this unique niche. For example, AsylumConnect created an app of resources on how to apply for asylum and a catalogue of LGBTQ-friendly services and organizations in the US for them to learn about. All four aim to validate LGBTQ asylum seekers and keep them safe.

Europe's generous social policies, such as allowing employees to retain their salaries while taking sick time to care for themselves or family members, may help to mitigate the coronavirus outbreak while also safeguarding the economy. Although the long-term impacts are yet unknown, in the short term, government-provided incentives are helping people and businesses stay afloat.

As the novel coronavirus outbreak continues to spread, the San Antonio Food Bank is working with other organizations to get more food out into the community. Although volunteer turnout has decreased, the Texas food bank has partnered with groups like Pre-K 4 SA to hand out food to students and their families. Every day, the food bank says it is sending $500,000 worth of food into the community.

Crime-tracking mobile apps give millions of Brazilians crowdsourced data on urban violence, alerting people to dangerous places and filling gaps in government data on shootings, robberies, and other risks. But apps such as Fogo Cruzado (“Crossfire”) and Onde Tem Tiroteio (“Where There's a Shooting”) offer statistically crude glimpses of crime, distorted by media and racial biases that one expert blames for myths about the risks people actually face.

An initiative on the Moscow metro system has posters on the train featuring cats and dogs that are looking for a home. Known as the “Tails and Paws” train, these animals come from 13 animal shelters in the city and riders can use their phone to scan the poster to learn more about the animals up for adoption. “It’s about forming a new culture of responsible attitude to animals,” says one of the workers at a shelter.

Two insurance companies, Discovery and Dialdirect, implemented a smartphone app for drivers to report potholes in their city. The companies then fill the potholes and brand them with their logos.
