In 1936, the museum received an Egyptian sarcophagus, which is believed to have contained the remains of an Egyptian woman from Kemet (Ancient Egypt). However, recent expert analysis reveals a ground-breaking discovery: the sarcophagus belongs to a Kushite woman, probably from the royal line of the Kushite Kingdom, which ruled Upper Egypt more than 2,000 years ago, marking the era of the Black Pharaohs. This discovery deepens our understanding of the interconnected histories of Egypt and Kush and challenges assumptions about the elites of ancient Egypt. The journey of the sarcophagus The sarcophagus, which has been kept in the museum for almost a century, has long been considered an artifact of ancient Egyptian culture. However, when archaeologists re-examined the skeletal remains, they noticed unusual bone structures that differed from typical Egyptian anatomy, prompting further research. Advanced DNA analysis linked the remains to the Kingdom of Kush, a powerful civilization that onc...

The decomposition of dead wood and plant matter is one of nature's most complex processes. This complex breakdown is necessary to maintain healthy ecosystems by allowing nutrients to return to the soil. However, it is also difficult due to the strength of the lignin and cellulose found in wood. However, fungi have evolved to break down these resistant plant components through their unique biological abilities. Research from the Netherlands Institute for Ecology (NIOO-KNAW) offers insight into how these organisms achieve this and why it is important for sustainable forest and agricultural management. Why is wood so difficult to decompose? Wood is mainly composed of cellulose, hemicellulose and lignin, which form a strong matrix. Lignin is particularly difficult to break down because of its complex molecular structure, which is both dense and resistant to enzymatic attack. This strong composition protects plants from disease-causing microorganisms and physical damage, but makes it di...

Every fall, countries around the world turn their clocks back to mark the end of Daylight Saving Time (DST). While the change provides an extra hour of morning light, it could have unintended consequences for wildlife. It has been proven that changes in people's commuting schedules and reduced visibility in the evening increase the number of collisions between vehicles and animals. This article explores why daylight saving time contributes to wildlife accidents, examines which animals are most affected, and highlights the economic and environmental impacts. The science behind daylight saving time and wildlife accidents Daylight saving time was originally designed to increase daylight during the workday, but research now shows that it disrupts human and animal behavior. When the clocks are turned back, drivers face twilight on their journey home, which reduces visibility and can increase the chance of vehicle collisions with animals.

Polar bears are an iconic species of the Arctic, but their survival is increasingly threatened by climate change. As temperatures rise, the sea ice that polar bears rely on for hunting is rapidly disappearing. This change has serious implications for their populations, health and ecosystem dynamics. Impact of climate change on polar bears Polar bears mainly hunt on the sea ice, waiting for seals, their main prey, to surface. However, due to climate warming, Arctic sea ice is melting earlier and forming later each year. This reduces the time bears can spend hunting, resulting in less food and poorer body condition. Bears are forced to spend more time on land, where food is scarce, and they struggle to meet their calorie needs. In addition, climate change affects their ability to reproduce and raise young. As sea ice shrinks, polar bears have to travel greater distances to find food, stressing pregnant females and reducing the chances of survival for their cubs. Key facts about the polar...
