Today’s stories bring hope for positive change. Facebook is reaching out to keep users safe, Dallas locals are saving dogs’ lives, and UT Dallas researchers are working to create a device that can imitate the sense of smell.

Dallas pets are finding foster homes every day with the help of a recently launched website. The Dallas Pets Alive organization and Dallas Animal Services are now registered on 911 Foster Pets, an online database that connects animals with local foster homes. The Dallas Morning News reported that Leslie Sans, director of Dallas Pets Alive, said foster care is one way to make Dallas a no-kill city. Learn more about foster care or register here.

Facebook is helping its users to be better friends to one another. On Tuesday, Facebook added new features that create an option to flag posts that appear concerning or suicidal. These posts will then come to the attention of Facebook’s specially trained global community operations team which works around-the-clock to monitor flagged posts. The New York Times has more about the new offering.

A research team at the University of Texas at Dallas is working to create an affordable electronic nose. Much like a hearing aid that emulates sound, this device would imitate the sense of smell. It would help with breath analysis for diagnosing a variety of health issues. The team is a part of the Texas Analog Center of Excellence and presented this research Wednesday at a technology conference in Honolulu, Hawaii. CMOS integrated circuits technology, used to manufacture most smartphones, will make the electronic noses less costly. A prototype could be ready for beta testing in early 2018.
