Sixteen-year-old Karl is seen for the first time in my optometry practice. He was referred to me for a fluctuating vision problem. During his examination, I saw signs suggesting he may have diabetes, which could have explained the fluctuating vision. This suspicion became a reality when his family doctor confirmed the diagnosis. Karl’s world was turned upside down.

As an optometrist, I invite you to dive into a reality that should concern us all.

Archaeologists in northern Iraq, working on the Mashki and Adad gate sites in Mosul that were destroyed by Islamic State in 2016, recently uncovered 2,700-year-old Assyrian reliefs. Featuring war scenes and trees, these rock carvings add to the bounty of detailed stone panels excavated from the 1840s onwards, many of which are currently held in the British Museum.

Advent calendars with hidden chocolatey treats, huge tins of Quality Street and steaming cups of hot chocolate festooned with whipped cream and marshmallows are all much-loved wintry staples at Christmastime. But how many of us stop to think about where chocolate actually comes from and how it made its way into our culinary culture?

The story of chocolate has a compelling, rich history that academics like me are learning more about every day.

In 2017, three researchers from the National Research Institute for Agriculture, Food and the Environment (INRAE), Denis Bourguet, Benoit Facon and Thomas Guillemaud, founded Peer Community In (PCI), a peer-review-based service for recommending preprints (referring to the version of an article that a scientist submits to a review committee).

The service greenlights articles and makes them and their reviews, data, codes and scripts available on an open-access basis. Out of this concept, PCI paved the way for researchers to regain control of their review and publishing system in an effort to increase transparency in the knowledge production chain.

If the media, popular entertainment, and retail habits are taken as indicators then the celebration of Christmas is no longer just the reserve of Christians. This has some consequences for the religious and non-religious alike.

In popular culture and the media, Christmas is portrayed as a time of happiness, togetherness, generosity, and peace. In the “made for Christmas” movies, such as those on the popular Hallmark Channel, a “feel good” message is the order of the day.

In the waning hours of the year’s biggest climate change conference – COP27 – we learned of a deal to create a loss and damage fund. This is essentially a source of finance to compensate poor countries for the pain they are incurring because of climate change. An often-cited example of such suffering is the ongoing drought in the Horn of Africa region, which has put some 22 million people at risk of severe hunger.
