A collection of recent studies and discoveries has brought to light interesting and contrasting stories in the realms of science, technology, and the environment. From the world of social media to the depths of the ocean, these findings offer insights into human behavior, technological advancements, and the natural world.

Research from The University of Texas at Arlington has found that highlighting others' achievements on LinkedIn sparks the most engagement. This study, which analyzed nearly 1,000 posts, suggests that interpersonal posts generate more engagement than business-focused content. According to Dr. Daniel Usera, the faculty member behind the study, celebrating colleagues and connections can be a more effective strategy for standing out on the platform.

Scientists in Germany have demonstrated a new form of surveillance that uses ordinary WiFi signals to identify people with near-perfect accuracy. By analyzing how radio waves bounce around a room, researchers can effectively "see" and recognize individuals, even if they are not carrying a device and even if their phone is turned off. This technology raises concerns about privacy and the potential for misuse.

The Bayeux Tapestry, an embroidered cloth nearly 70 meters long, tells the story of the Battle of Hastings in 1066 and William of Normandy's defeat of Harold Godwinson, King of England. However, the tapestry only tells the winner's side of the story. Old English texts offer a glimpse into the other side of the battle and its impact on English people.

Wildfires are no longer confined to dry Mediterranean landscapes. In recent years, they have started to extend into regions more commonly associated with rain-soaked hills and bogs. The Scottish Highlands and Irish uplands have seen an increase in wildfires, with major fires breaking out across Scotland, Northern Ireland, and Ireland.

New research has revealed a recent increase in sightings of blue and fin whales in the southeastern Atlantic. The findings, published in the African Journal of Marine Science, compile more than 60 years of confirmed sightings and strandings from Namibia and South Africa's west coast. Although overall numbers remain low, sightings of both species have increased markedly in recent years, with 95% of observations recorded since 2012.

• What: Study on LinkedIn engagement, WiFi surveillance, Bayeux Tapestry, wildfires, and whale sightings
• When: Recent studies and findings

As we move forward, it will be interesting to see how these findings impact our understanding of human behavior, technology, and the environment. Will we see a shift towards more interpersonal posts on LinkedIn? How will WiFi surveillance technology be used and regulated? What can we learn from the Bayeux Tapestry and old English texts about the Battle of Hastings? How will we address the increasing risk of wildfires in cool climates? And what does the recovery of blue and fin whales mean for conservation efforts?
