Florida State University Dean of the College of Human Sciences Michael Delp has detailed a sad reality affecting the Apollo astronauts: cardiovascular health issues caused by their exposure to space radiation. According to the study recently published in Scientific Reports, the astronauts who travelled into space as part of the lunar missions are largely suffering cardiovascular effects as a result, … Continue reading
Thinking that deleting your WhatsApp chat is good enough to erase it from existence? Maybe if you’re trying to hide a conversation from someone not so tech savvy, we guess maybe it could work, but for those who are more skilled, like law enforcement agencies or security researchers, it seems that your deleted chats aren’t 100% deleted.
According to a post by security researcher Jonathan Zdziarski, he has examined disk images from the latest build of WhatsApp and discovered that your deleted chats aren’t actually fully gone from your phone. Instead it seems that there is a forensic trace of the chat logs left behind, meaning that for the person with the right skills, it’s almost as good as if the chats weren’t deleted in the first place.
Zdziarski notes that this problem is solely a WhatsApp problem, but rather with apps on iOS that rely on SQLite, and that deleting a record basically adds it to something called a “free list”. “If you delete large chunks of messages at once, this causes large chunks of records to end up on this ‘free list’, and ultimately takes even longer for data to be overwritten by new data. There is no guarantee the data will be overwritten by the next set of messages. In other apps, I’ve often seen artifacts remain in the database for months.”
So like we said, anyone with the tools could potentially gain access to your messages. Zdziarski also provided some tips and how end-users could potentially protect themselves, and also how developers such as WhatsApp could mitigate this problem in future builds, something that we hope the company will pick up on.

There are several services and online websites that require users to have two-factor authentication. A good example would be banks where you might be required to key in a one-time code to verify you are who you say who are when making purchases online, or when trying to transfer funds to someone else.
That being said it looks like WhatsApp could be gaining that functionality soon. According to the latest beta of WhatsApp, a series of files has been discovered inside the APK that make reference to two-factor authentication, although exactly what this will be used for remains to be seen as the folks at The Android Soul have not found anything in the beta app itself that would need the feature.
Now since WhatsApp requires a code when being installed for the first time, or when you’re installing the app on a new phone, it has been speculated that maybe the two-factor authentication could be used for this. However the current system already works so we’re not sure why WhatsApp would change that.
It is possible that maybe this is for when trying to retrieve backup chats, and WhatsApp wants to make sure that you are the owner of the phone. In any this is just speculation but there are some references, so maybe we will find out more about the feature in future builds.

If you’re on Facebook and you have your birthday listed, there’s a very good chance that once a year, your Facebook page will be flooded with posts from your friends, colleagues, and relatives wishing you a happy birthday. However this can get rather messy if there are a ton of messages, which is why Facebook wants to streamline the process.
This will be done in the form of a video, where Facebook will basically collate all the birthday messages you’ve received into a cute little video, similar to the other videos that Facebook has thrown together in the past, such as friendship reminders, looking back on the year, and other similar videos.
When you receive the video, users will also have the option of replacing the photos that Facebook has chosen to use, or the posts that they have picked (maybe you don’t want your ex’s message to appear so publicly), and when you’re done editing it in the video editor, you’ll have the option of sharing it with your friends.
It’s not exactly a groundbreaking feature or one that will make or break Facebook, but for a website that wants to be your “home” for everything, whether it be for work, news, play, and social, we guess it’s a nice touch.

WASHINGTON, July 29 (Reuters) – A U.S. appeals court on Friday struck down a NorthCarolina law that would have required voters to show photo identification when casting their ballots in the November presidential election.
Critics argue that the North Carolina law, like similar provisions in other U.S. states, disproportionately impacts minorities and poor people who do not have drivers’ licenses or other forms of state-issued identification. (Reporting by Andy Sullivan)

“I became an educator because I was pretty sure I could change the world.”
It’s not every day that you meet someone with both the conviction to dream big and the courage to make those dreams a reality. But when Aimee Cribbs, Ed.D., submitted her entry to PeopleAdmin’s Inspired2Educate program, I knew instantly that we had uncovered a special educator who deserved to be honored.
Inspired2Educate honors and celebrates our nation’s educators, while at the same time inspiring young people considering a career in education. The program calls for current educators to share stories of a K-20 teacher, administrator, or school staff member who inspired them to pursue education as their life’s work.
Dr. Cribbs works as both a graduate studies adjunct professor at Piedmont College and as an art and health teacher at Ellijay Elementary School in Georgia. While the age range of her students varies widely, the lessons she teaches are truly timeless. Interviews with former students and current colleagues highlight Dr. Cribbs as an outstanding role model for her students and peers who works hard to instill confidence, critical thinking, and work ethic into every young mind that steps into her classroom.
This has been the case since day one, almost 20 years ago, when Dr. Cribbs began her first year of teaching. “We were her very first class out of college, and I remember we gave her such a hard time,” said Paisley Brown, one of Dr. Cribbs’ first students in that inaugural fifth-grade class. “But the thing that stands out to me most is that I remember she really cared, and at that time in my life, I didn’t really have good home support. She looked out for me the best way she could as a teacher and always made me feel safe. Even after I left elementary school, she would still check in on me — she even came to my high school graduation, a two-hour drive from where she lived, which was an awesome moment.”
That kind of dedication and compassion made a life-long impact on Paisley, who credits Dr. Cribbs with inspiring her decision to pursue a career in education. “I reached out to her and asked if she could imagine me being a teacher one day. She was the first person I thought of when I began the decision-making process, and I told her that she would know better than anyone if I could do it,” she said. Dr. Cribbs, who has remained a close mentor to Paisley for nearly two decades, told Paisley with confidence, “You can do it, and you should do it.”
Another former fifth-grade student of Dr. Cribbs’ remembers not only her compassion, but also her courage to bring complex issues into the classroom as lessons for her young students. “I remember once she made us jog around the school during recess, and when we got back to her classroom, some of our seats were missing and many of the students didn’t have a place to sit,” said Aikeem Cooper. “She then proceeded to teach us about Rosa Parks and discrimination. She wasn’t afraid to bring that difficult lesson to life, and I credit her to this day for being, in many ways, my introduction to the real world.”
Aikeem, who now works as a criminal defense lawyer, said that Dr. Cribbs provided him with the foundational critical thinking skills necessary to flourish in that role. “She taught us to stand out and question things and learn as much as we could about the world,” he said. “She allowed us to express ourselves creatively, and gave me the confidence I needed to study law.”
When asked what ultimately inspired her to become a teacher, Dr. Cribbs points to her father and aunt, both life-long educators. But she said that, without a doubt, her fourth-grade teacher, Mrs. Scholz, had the most profound influence on her career choice. “I can’t remember the topics we studied over three decades ago, but I can remember how Mrs. Scholz made me feel. She made me feel intelligent, important, and capable of anything I set my mind to doing,” she said.
Dr. Cribbs has proven time and again that she is indeed capable of anything she sets her mind to doing. Even in pursuit of her ultimate goal: changing the world.
“I believe in myself and my ability to leave the world a better place,” she said. “Twenty years and thousands of students after my first day in the classroom, I still trust that nothing has the power to shape the future like education.”
When asked what advice she would give to those thinking of becoming an educator, she said, “What we do can often seem really small; in many ways, it’s just one student at a time. But if you make one person change the course of their life, I mean, that’s huge.”
Congratulations, Dr. Cribbs, on your selection as an Inspired2Educate honoree. We are delighted to share your story, and cheer you on as you continue to change the world, one student at a time.

It is 5 a.m. when the alarm clock rings at Thaiza Vitória da Silva’s home in Anchieta, a neighbourhood in northern Rio de Janeiro, Brazil. The sun hasn’t risen, but the 15-year-old handball player is already up and getting dressed. She walks to the bus station with her father Marcos and her little sister Thais Maria.
When the bus arrives, the two girls say goodbye to their father and start a one-hour ride to Santa Monica Educational Centre, a private school with a strong sport tradition. The sisters haven’t always studied there. Thaiza started her formal education in a lower quality public school because her family couldn’t afford a private education.
It was her outstanding performance as a handball player that earned her an athletic scholarship to study at Santa Monica. Inspired by Thaiza, her sister too plays handball and has been awarded a scholarship to study at Santa Monica. To keep the scholarship, Thaiza must maintain high grades in other subjects, in addition to being a good athlete. Thaiza enjoys the endeavors. “I’ve learned that being a leader is not about bossing around, but being able to become an example and listen to others,” she says.
After classes end for the day, Thaiza takes off to the Olympic Villa of Mato Alto in Jacarepaguá, a neighbourhood in the west of Rio de Janeiro. It is one of 22 public spaces with free sport facilities managed by the municipality.
From 3 to 5 p.m., she practices handball. Once a week she starts her training an hour late so she can join 20 other girl athletes to participate in the ‘One Win Leads to Another’ workshops. The workshops are part of a joint programme by UN Women and the International Olympic Committee in partnership with the organization Women Win.
The workshops offer a safe space for the girls to talk about gender inequalities, to work on their self-esteem and leadership skills, to learn about their bodies and health, to gain financial literacy and knowledge on how to access public services if they experience gender-based violence.
Myriam Romi, one of the 50 facilitators in the programme, says the workshops have helped Thaiza, who used to be a shy and introspective girl, to express herself with more confidence and build her own identity.
On the court, Thaiza has always been determined, focused and strong. She runs, jumps, laughs, shouts, insists on fairness from referees, and cheers her team on to victory. Through the programme, she is now expanding this energy to other areas of her life.
During the Torch Relay for the 2016 Rio Olympic Games, Thaiza has a very important duty. She’s excited to be carrying the torch representing the 400 girls currently participating in the ‘One Win Leads to Another’ programme. “There is a new path of opportunities opening in my life, in our lives,” she says.
