Coined by Charles Darwin, the term "living fossils" is used to describe living creatures that have stood the test of time — hardy and resilient organisms that have remained largely unchanged for millions of years. Here are some of of the most incredible examples of nature not fixing what ain't broke.
For the first time since 2009 Lake Superior has frozen thick enough to safely permit access to the ice caves at the Apostle Islands National Lakeshore in northern Wisconsin. An estimated 1,000 people are arriving daily to trek out to the islands for a glimpse of frozen caves which are covered in a cascade of icicles formed from water runoff and waves that splashed against the caves before the surface solidified. If the weather holds out, officials estimate the caves could remain open for another month. A huge thanks to Kelly Marquardt, Andy Rathbun and the Wisconsin Department of National Resources for sharing photos of the caves.

(Phys.org) —When Danielle Ludeman decided to leave her hometown of Vancouver to study evolutionary biology at the University of Alberta, she knew she was in for a challenge that would help her discover things about science and, in turn, herself.
The level of the Dead Sea has continued to drop. Despite heavy rains in the past three monts and lower than normal temperatures, the Dead Sea has fallen another 3 cm. Water level has reached a level of 427.82 meters (1,403 feet) below sea level....

Confronted with the loss of sea ice in some parts of Antarctica, four colonies of emperor penguins have come up with an innovative breeding strategy to adapt to their changing environment. Using satellite images, an international team of scientists tracked the four colonies from 2008 to 2012. In the first three years, the emperor penguins hatched and incubated eggs in their customary fashion — atop the sea ice that freezes during the Antarctic winter and spring. But in 2011 and 2012, sea ice did not form until a month after the breeding season began. As a result, the emperor penguins — the largest penguin species on earth — did something never before witnessed by scientists: They climbed up the nearly sheer walls of large, floating ice shelves — huge structures, often hundreds of square miles in extent, that flow from land-based glaciers into the sea. In the region of the four colonies, the ice shelf walls reach as high as 100 feet, researchers say. The scientists say the altered breeding behavior could demonstrate how ice-dependent emperor penguins may adapt to life in a warming world.
Understanding who feeds on whom and how often is the basis for understanding how nature is built and works. A new study now suggests that the methods used to depict food webs may have a strong impact on how we perceive their makeup.
Iconic migration, health of Mexican forests in jeopardy
In winter, central Mexico’s highland forests should be pulsing with orange and black. Not this year. Monarch butterfly colonies now cover less than a single hectare of forest, the smallest swath of land since data collection began in 1993, scientists reported at a press conference here today. The paltry figure highlights the uncertain fate of a natural wonder: the monarch’s 4000-kilometer migration between North and Central America.
This is my third short-film about the northern lights. This year some epic displays has been on the sky, and for the first time I have included real-time recordings.
As usual, my main focus is on getting the auroras show as close as possible to real-time speed given the time available in a short video. Although in a few sequences I have accepted overdoing the speed to better enhance other elements, such as moving fog, faster pans, clouds, milky way etc.
In the film I have tried to show the slower majestic dancing lights, as well as the more faster, dramatic and abstract shows, and finally the auroras in combination with city lights and urban elements.
When pondering the number of extraterrestrial civilizations, it is worth noting that even after it got started, the success of life on Earth was not a foregone conclusion. We recount some thrilling episodes from the history of our planet, some well-documented but others merely theorized: our collision with the planet Theia, the oxygen catastrophe, the snowball Earth events, the Permian-Triassic mass extinction event, the asteroid that hit Chicxulub, and more, including the global warming episode we are causing now. All of these hold lessons for what may happen on other planets.
A massive ancient subglacial trough – deeper than the Grand Canyon - has been discovered by a team of UK experts.
The research involved scientists from Newcastle University, the University of Bristol’s Glaciology Centre, the British Antarctic Survey and the universities of Edinburgh, Exeter, and York. They charted the Ellsworth Subglacial Highlands – an ancient mountain range buried beneath several kilometres of Antarctic ice - by combining data from satellites and ice-penetrating radars towed behind skidoos and on-board small aircraft.
With a wild population estimated at fewer than 400 individuals, South Africa’s riverine rabbit (Bunolagus monticularis) is just a hare’s breath away from extinction. Most of the rabbit’s habitats in the Karoo semi-desert region have been developed over the past five decades, and the few remaining animals live in increasingly fragmented groups far away from one another on farms and other private land. Conserving the critically endangered, nocturnal rabbits, therefore, is a challenge.
