This Wednesday the 9th of April at 2PM PDT on Twitter,@STEMWomen will lead an online discussion on how we can improve women's participation in STEM. We'll talk about how we can address intersections of discrimination in STEM, including gender, race, LGBTQI issues, as well as other forms of exclusion. We'll also focus on the creative ways to improve science outreach to disadvantaged and marginalised groups. Join our discussion on Twitter using #ScienceChat . Our talented guests are all STEM outreach & diversity advocates:

One of our balloons has had quite a journey over the past few weeks. It did a lap around the world in 22 days, and has just clocked the project’s 500,000th kilometer as it begins its second lap. It enjoyed a few loop-de-loops over the Pacific ocean before heading east on the winds toward Chile and Argentina, and then made its way back around near Australia and New Zealand. Along the way, it caught a ride on the Roaring Forties — strong west-to-east winds in the southern hemisphere that act like an autobahn in the sky, where our balloons can quickly zoom over oceans to get to where people actually need them.
Traversing the stratosphere is particularly challenging this time of year because the winds actually change direction as the southern hemisphere moves from warmer to colder weather, resulting in divergent wind paths that are hard to predict. Since last June, we’ve been using the wind data we’ve collected during flights to refine our prediction models and are now able to forecast balloon trajectories twice as far in advance. In addition, the pump that moves air in or out of the balloon has become three times more efficient, making it possible to change altitudes more rapidly to quickly catch winds going in different directions. There were times, for example, when this balloon could have been pulled into the polar vortex – large, powerful wind currents that whip around in a circle near the stratosphere in the polar region – but these improvements enabled us to maneuver around it and stay on course. We can spend hours and hours running computer simulations, but nothing teaches us as much as actually sending the balloons up into the stratosphere during all four seasons of the year.
Take a look through our photo album to see some of the specific improvements that have been made to the balloon technology, thanks to the lessons we’ve learned in flight.
We've passed two milestones recently. Firstly, we're actually up to 251.4K members now - and we wanted to thank you, our members! Secondly, we're the 9th largest Community on Google+! That's all thanks to you!
We appreciate your fascinating science posts, your spirited debate and your generous feedback to our fellow members who ask for science input. We'd like to highlight some of our Curator's Choice posts. Further celebrations will follow!

It seems a few days ago a major flaw was found in the main way security is done on the internet.
The flaw would let hackers steal passwords easily and it's been there for the past two years before it was found, we don't know if hackers knew about it already. So, while we don't know if anyone's passwords have been stolen, almost any time you logged into a website in the past two years could have been an opportunity for someone to steal your password.
So, sometime soon, maybe over the weekend, you should consider coming up with a couple new, good, strong passwords and logging in to all your important websites and changing them. Like banks, government services (CRA had this bug), email, facebook, amazon, netflix etc. Definitely any site that has your credit card information or address.
Tips on coming up with a good password:

This is a great idea. I don't know if they are all fully to scale but making very accurate planetary representations in cake form is educational and tasty. But they only have some of the more obvious planets done. How would you do a Europa cake? Or a Saturn cake?
