In the southern Egyptian city of Luxor, site of the ancient metropolis of Thebes, two new artifacts have been added to a place that is already crowded with mysteriesÂ of Egypt's distant past. The burial sites are located on the western bank of the Nile river, the water source that played such a central role in ancient Egyptian life and culture. The cemetery, or necropolis,Â in which the tombs are located is a known burial place of top officials from the 18th dynasty, according to the Associated Press.
The migration of tens of millions of red crabs across Australia's Christmas Island is a spectacular natural phenomenon, and Google Street View plans to capture it this year as part of their amazing Google Trekker gallery.
Research has shown that people report the highest levels of happiness after the age of 55 in three key areas: their financial situation, their physical appearance, and their overall well-being. Meanwhile, in all three areas, people reported the lowest levels of happiness between the ages of 45 and 59, according to data from the Centre for Economic Performance, Proceedings of the National Academy of Sciences, and the General Social Survey.
The humble potato -- drought-resistant, able to thrive in diverse soils, and enjoyed fried, steamed or baked -- brought centuries of relative calm and prosperity to Europe after its introduction in the 16th century, a new study says. The blessings that flowed from this agricultural revolution helped ease the economic and societal pressures that can lead to costly and disastrous conflicts, says the report. The introduction of potatoes and the resultant increase in productivity "dramatically reduced conflict" both within and between states for some two centuries, it says.
After landing on Baffin Island, Canada, wildlife photographer and environmental activist Paul Nicklen captured video of a frail polar bear â€” dying and foaming from the mouth â€” as the weak animal collapsed to the ground. The bear will soon be dead â€” if it isn't already.Â On Dec. 5, Nicklen posted the grim video to his Instagram account, and since then, it's been stirring Â emotions around the web. Polar bears are, for better or worse, a symbolic species when it comes to global warming, and many are seeing this video as a new warning sign.Â Fortunately, however, the condition of this bear is not representative of most polar bear populations â€” at least not yet.Â SEE ALSO: Trump shrank 2 national monuments by nearly 2 million acres. He can't do that to Yellowstone. There are 19 different populations of polar bears in the expansive Arctic. The dwindling sea ice here â€” which these predators need to hunt fat-rich seals â€” is now affecting different groups of bears in different ways. "Itâ€™s tough to see a disturbing image like that and not feel sympathy for the animal," U.S. Geological Survey (USGS) polar bear biologist Todd Atwood said in an interview. "Itâ€™s also tough to see an isolated image extrapolated to some kind of population level effect." The actual cause of the bear's death will remain unknown, but Atwood doubts there's one specific cause. "Itâ€™s probably a combination of things â€” it could be an old animal â€” but it also could be that if itâ€™s still on land, that thereâ€™s not enough sea ice," he said.Â My entire @Sea_Legacy team was pushing through their tears and emotions while documenting this dying polar bear. Itâ€™s a soul-crushing scene that still haunts me, but I know we need to share both the beautiful and the heartbreaking if we are going to break down the walls of apathy. This is what starvation looks like. The muscles atrophy. No energy. Itâ€™s a slow, painful death. When scientists say polar bears will be extinct in the next 100 years, I think of the global population of 25,000 bears dying in this manner. There is no band aid solution. There was no saving this individual bear. People think that we can put platforms in the ocean or we can feed the odd starving bear. The simple truth is thisâ€”if the Earth continues to warm, we will lose bears and entire polar ecosystems. This large male bear was not old, and he certainly died within hours or days of this moment. But there are solutions. We must reduce our carbon footprint, eat the right food, stop cutting down our forests, and begin putting the Earthâ€”our homeâ€”first. Please join us at @sea_legacy as we search for and implement solutions for the oceans and the animals that rely on themâ€”including us humans. Thank you your support in keeping my @sea_legacy team in the field.

Bears are going to starve to death. This is what a starving bear looks like." But while the threat to polar bears is real, all is not yet dire for the Arctic predators.Â "Itâ€™s worth noting that there are some subpopulations that are believed to be stable," said Atwood. Polar bears are listed as a threatened species in the United States, which means that while they're not yet on the brink of extinction, they "are likely to be at the brink in the near future," according to the U.S. Fish and Wildlife Service, which maintains the list. For polar bear populations that are struggling, it's often due to a lack of sea ice. Polar bears can't hunt seals on the open water. "So as the open water season gets longer, thereâ€™s association between the length of the open water seas and body conditions â€” body conditions decline," Atwood said. But this isn't the full story. The physical condition of polar bears is also dependent upon how much fish is available for seals. So in places with more fish and seals â€” places that are more "biologically productive" â€” there will be more food for bears, and they're likely to be better fed.Â Unless, of course, there's no sea ice there, either.Â There is a clear solution to polar bears' vulnerability â€” and you undoubtedly know it well: Humanity's commitment to limit global warming, which is caused by fossil fuel emissions. These heat-trapping gases warm both the oceans and the air, resulting in vastly diminished sea ice, particularly in the summer and fall.Â "This requires changing our behaviors relative to our carbon footprint," Atwood said.
