This All-Female Unit Of Rangers Protecting Wildlife From Poachers In Zimbabwe Is Epic. Poaching is slowly becoming a thing of the past in parts of Zimbabwe!

This All-Female Unit Of Rangers Protecting Wildlife From Poachers In Zimbabwe Is Epic

A highly-effective all-female anti-poaching ranger unit called the Akashinga is protecting wildlife and revolutionizing the fight against illegal trophy hunting. Since being founded in 2017 as part of the International Anti-Poaching Foundation (IAPF), the Akashinga (meaning The Brave Ones in the Shona language) helped reduce elephant poaching in Zimbabwe’s Lower Zambezi Valley by a whopping 80 percent. Earliest evidence for humans in the Americas. Image copyright Ciprian Ardelean Humans settled in the Americas much earlier than previously thought, according to new finds from Mexico.

Earliest evidence for humans in the Americas

They suggest people were living there 33,000 years ago, twice the widely accepted age for the earliest settlement of the Americas. The results are based on work at Chiquihuite Cave, a high-altitude rock shelter in central Mexico. Archaeologists found thousands of stone tools suggesting the cave was used by people for at least 20,000 years. Overlooked No More: Eunice Foote, Climate Scientist Lost to History.

Overlooked is a series of obituaries about remarkable people whose deaths, beginning in 1851, went unreported in The Times.

Overlooked No More: Eunice Foote, Climate Scientist Lost to History

In the 1850s, Eunice Foote, an amateur scientist and activist for women’s rights, made a remarkable discovery about greenhouse gases that could have helped form the foundation of modern climate science. But the scientific paper she published that might have added her name to the pantheon of early climate scientists was quickly forgotten, and she faded into obscurity. In India, there's water everywhere, and nowhere. SciShow Kids. History of the entire world, i guess. Himalayan glacier melting doubled since 2000, spy satellites show. The melting of Himalayan glaciers has doubled since the turn of the century, with more than a quarter of all ice lost over the last four decades, scientists have revealed.

Himalayan glacier melting doubled since 2000, spy satellites show

The accelerating losses indicate a “devastating” future for the region, upon which a billion people depend for regular water. The scientists combined declassified US spy satellite images from the mid-1970s with modern satellite data to create the first detailed, four-decade record of ice along the 2,000km (1,200-mile) mountain chain. Microscopic Images Of Seeds. The diversity and intricacy of shapes and sizes of seeds is extraordinary.

Microscopic Images Of Seeds

Even more amazing is that within even the tiniest of seeds lies the complete genetic information required to birth and structure such organisms as the complex passion flower, or a 360 foot tall sequoia. Seeds are also amazing travelers, either with the help of the wind or by hitching rides with neighboring wildlife. If stored in ideal conditions, seeds can also spring to life, after hundreds of years of lying dormant. More often than not, the smaller the seed, the more texture found on its surface.

The tragic story of America's only native parrot, now extinct for 100 years. It was winter in upstate New York in 1780 in a rural town called Schoharie, home to the deeply religious Palatine Germans.

Suddenly, a flock of gregarious red and green birds flew into town, seemingly upon a whirlwind. The townspeople thought the end of the world was upon them. Though the robin-sized birds left quickly, their appearance was forever imprinted on local lore. As author Benjamin Smith Barton wrote, “The more ignorant Dutch settlers were exceedingly alarmed. Sea turtles use Earth's magnetic field like a GPS to find their birthplace. Although they might not have seen or been to their nesting grounds for decades, loggerhead turtles (Caretta caretta) know how to come back home with impressive accuracy rivaling man-made GPS.

Now, a new study found just how exactly the turtles manage this feat: they use Earth’s magnetic field to navigate across miles and miles. Credit: Public Domain. For years, the loggerheads swim in loops from their nesting sites in North Carolina and Florida to North Africa. Despite the vast distances they cover, the turtles always manage to find their way home, returning to their nest beaches within about 40 to 50 miles of where they were originally born. “Loggerhead sea turtles are fascinating creatures that begin their lives by migrating alone across the Atlantic Ocean and back,” says Kenneth Lohmann, professor of biology at the University of North Carolina at Chapel Hill. What is a Supervolcano? As the name implies, a supervolcano is an extremely large volcano, capable of ejecting over 1,000 cubic kilometers (240 cubic miles) of deposits.

There are six known supervolcanoes and twelve known super-eruptions. Graphic scale of known volcanic and supervolcanic eruptions. Image in public domain. What is a supervolcano If we want to see what makes a supervolcano, we need to first understand what a volcano is — and what makes it ‘super’. Mitochondria mutation mystery solved: Random sorting helps get rid of duds. You probably know about the 23 pairs of chromosomes safely stowed in your cells’ nuclei. That’s where the vast majority of your genes can be found.

But there are 37 special genes — a very tiny fraction of the human genome — located in mitochondria, the structures inside your cells that breathe and produce energy. Repeated copying of mitochondrial DNA introduces errors; if not kept in check, these mutations can give rise to incurable diseases like Leigh syndrome and Leber’s optic neuropathy.

Growing up in southwestern Pennsylvania, Patrice Tomcik had never heard of Lyme disease — an infectious, flu-like illness transmitted by ticks. But in the last few years, five of her friends have caught it, she's had to have her dog vaccinated and she regularly finds herself pulling ticks off her children.

Coral Reefs 101. How Many Moons Does Each Planet Have? Jane Goodall: A History. Early modern humans formed complex social networks to avoid inbreeding as early as 34,000 years ago. Even in small Paleolithic communities that lived 34,000 years ago, our early ancestors seem to have been aware of the dangers of inbreeding. Anthropologists report finding evidence of complex social structures at a site in Sunghir, Russia, which suggests people took precautions against inbreeding. How does fracking work? - Mia Nacamulli.
