If you haven’t watched the Jodie Foster film Contact, watch it now. We’ll wait.

Good, you’re back. So, do you believe she was transported through a wormhole to a distant civilization? If you do, this course is for you. It’s also for you if you don’t, because as a science, astrobiology applies rigorous critical reasoning to basic questions like ‘Is there anybody else out there?’, ‘What other forms of life are possible apart from us?’ and ‘What are the conditions elsewhere in the cosmos that might support life?’

Sometimes at school students miss something important due to absence, inattention, teacher sickness or sporting commitments. Alternatively they might struggle with the subject in general and need extra support to get them through the year with good grades. Conversely, some students may be particularly fascinated by a subject and wish to deepen their knowledge. In the case of geometry, which forms the foundation for many disciplines and, ultimately, careers, taking extra online classes from an expert can help students to really nail down this fundamental subject.

The 2017 hurricane season has been one of the most violent on record, with the highest number of major hurricanes since 2005 and it’s not even over yet. The storms have marched across the Atlantic in seemingly endless succession, and the alphabetic-order names have kept coming: Gert, Harvey, Irma, José, Katia, Lee, Maria, Nate, Ophelia … let’s hope at the time of writing that there isn’t a Philippe.

A virtual reality simulation of a nuclear facility is one of the new training tools presented at the 61st IAEA General Conference in September. Training specialists will be using it to navigate through realistic scenarios, threats and risks. The 3D tool is focused on preventative and protective measures against insider threats, and there are plans to cover other areas of nuclear security in the future.

It’s very British to talk about the weather. So it’s fitting that a British university – the University of Reading – offers a 3-week course called Come Rain or Shine: Understanding The Weather. Taking this course will have the effect of turning comments like ‘Looks like rain tomorrow’ into more technical and perhaps even accurate predictions. Cows lying down might mean it’s going to rain, but for the curious who want to know why it’s going to rain, this course is perfect.

Have you ever wanted to solve a crime? It seems to be a common fantasy – stepping into the shoes of a flinty-eyed detective, assessing the evidence and leaving no stone unturned to tighten the net around the criminal until he is forced to confess. These days a lot of that work is done via forensic science. There are quite a lot of games on the Google Play and Apple Stores based on forensic TV shows like CSI and NCIS in which you analyse the evidence to deduce who committed the crime.
