Wildlife: Ngorongoro Crater In Tanzania (4K)

Video Leave a comment

The Ngorongoro Conservation Area spans vast expanses of highland plains, savanna, savanna woodlands and forests. Established in 1959 as a multiple land use area, with wildlife coexisting with semi-nomadic Maasai pastoralists practicing traditional livestock grazing, it includes the spectacular Ngorongoro Crater, the world’s largest caldera.

The property has global importance for biodiversity conservation due to the presence of globally threatened species, the density of wildlife inhabiting the area, and the annual migration of wildebeest, zebra, gazelles and other animals into the northern plains. Extensive archaeological research has also yielded a long sequence of evidence of human evolution and human-environment dynamics, including early hominid footprints dating back 3.6 million years.

Science: Longer Lives And Slower Mutations, The Largest Galaxy Structure

Audio Leave a comment

For biologists, a long-standing question has been why some animals live longer than others. This week a team have attempted to answer this, by measuring the rates that different animal species accumulate mutations. They show that longer-lived animals acquire mutations at a slower rate, which helps to explain why cancer risk does not scale with lifespan.

10:43 The war in Ukraine’s effects on global energy

Many European countries are dependent on Russian fossil fuels for energy production. Following Russia’s unprovoked invasion of Ukraine, these countries are looking to wean themselves off these fuels, which could have short- and long-term impacts on emissions and food production.

19:58 A new measurement of a particle’s mass hints at new physics

Last week, a new estimate of the W boson’s mass caused much excitement among physicists. The result suggests that this particle is heavier than theory predicts, a finding that could be the first major breach in the standard model of particle physics. However, measuring W bosons is notoriously tricky, and further work will be needed to confirm the finding.

Wildlife Views: ‘Giraffe – A Silent Extinction’ (Video)

Video Leave a comment

The giraffe is an icon of Africa, thousands of tourists travel around the globe every year to see them in the wild, yet in the last century giraffes have gone extinct in 7 countries and their numbers continue to fall dramatically. Since the mid-eighties, giraffes have been on a steady decline. Population numbers have dwindled by 40%, leaving less than 70,000 adults in the wild. That is just one giraffe for every five African elephants, yet very few people are aware of their situation. Over the course of a year the film crew travel across the continent to join the fight to save these gentle giants, bringing awareness to their plight and ultimately, helping to prevent its silent extinction.

New Wildlife Videos: “The World Without Giraffes” – Can We Save Them?

Video Leave a comment

Since time immemorial, giraffes have captivated the human imagination. Yet the total giraffe population has fallen 30 percent in the past few decades, and very few people have seemed to notice. “Giraffes are all over the place in popular culture,” says the Atlantic staff writer Ed Yong. “I think because of that, we forget that, actually, they are endangered.” In a new episode of The Idea File, Yong explains why it’s crucial to channel our reverence for these beloved animals into tangible conservation efforts.
