Can baby birds really imprint on humans?

Image
Imprinting is a survival strategy that occurs when a newly hatched bird sees another animal and then forms a strong attachment to it. Usually, it’s the baby’s mother, but sometimes it can be an inanimate object, such as a stick, or a different animal, such as a human. The most impressive demonstration of this has to be from Italian hang glider pilot Angelo d’Arrigo . He reared a flock of Siberian cranes under the wing of his hang glider, and then in 2003, guided them all the way from northern Siberia to the Caspian Sea in Iran; a journey of 5,500km.

The best Kindle and Kobo e-readers for 2023

Image
Calling all avid book readers who travel a lot, those looking to reduce their overwhelming physical book collection, or even just anyone after a new way to make their commute more interesting, an e-reader could be the new piece of tech you need in your life. These digital book libraries are small, offer a long battery life and are capable of storing thousands of books. The big question is which one you should choose. While there are plenty of brands out there, the two big ones are Kindle and Kobo. We’ve picked out the best e-readers from both of these brands, listing them below. Kindle or Kobo? The most well-known brand of e-reader is easily Amazon’s Kindle. However, it’s not the only quality brand out there, and many readers choose a Kobo instead. Kindles and Kobos each have access to their own ebook stores. I have found that the Kobo store can feel a bit limited at times, especially if you venture off the bestseller list, but David Price from Tech Advisor reports no difference...

What is toxic positivity?

Image
Toxic positivity comes from the belief that, despite an individual’s emotional pain or challenging situation, they should still adopt a positive outlook. It denies, invalidates and delegitimises emotions that aren’t ‘happy’ and includes phrases such as “turn that frown upside down”, “it could be worse” or, a social media favourite, “good vibes only”. Studies have shown that suppressing feelings can lead to increased stress , anxiety and depression in the long run. More effective is trying not to label emotions as ‘good’ or ‘bad’, instead recognising that it’s okay to feel sad, angry or frustrated, and remembering that emotions will eventually pass.

What makes someone an adrenaline junkie?

Image
Blood flow increases to your muscles, your attention sharpens, and your pupils dilate. Adrenaline is chemically related to the pleasure hormone dopamine, and dangerous situations can also cause your body to produce endorphins, which suppress pain and heighten pleasure. These systems may have evolved because a certain amount of risk-taking has survival value – we are descended from people brave enough to hunt mammoths, after all. There are specific genes that increase the ‘adrenaline high’ for some people, and a 2002 study for the World Health Organization found these genes in both adrenaline junkies and drug addicts.

Have face masks become less effective at managing COVID?

Image
With fresh concerns surrounding rising flu, Strep A and COVID Omicron sub-variant XBB.1.5 cases, health officials across the UK are scratching their heads over one key question: should we all be wearing masks again? While the UK Health Security Agency (UKHSA) has advised adults who are displaying symptoms of flu or COVID to wear a face covering, some public figures have advised all healthy adults to wear a mask in certain settings. For instance, in a briefing on 9 January, Scottish First Minister Nicola Sturgeon stated: “We continue to advise those over the age of 12 should wear face coverings when on public transport or in public indoor spaces.” However, as COVID begins to stabilise in the UK, some scientists have questioned how effective face masks are at controlling current case numbers. “Masks were really helpful early in the pandemic. And for people to argue that masks weren’t is seriously wrong,” Prof Paul Hunter from the Norwich Medical School of the University of East An...
