The first signs of the disease are so subtle that they can be tricky to catch. Sometimes, they come in the form of rude remarks or an occasional out-of-character comment. Sometimes, they appear as a struggle to stay organized or an increase in impulsive spending. And sometimes, wrong words and slurred sentences are the initial indications. Though these symptoms can seem small, frontotemporal dementia worsens with time, transforming the way that people act and communicate. Destroying the brain fr ...read more
Rusty-patched bumble bees (Bombus affinis), are crucial pollinators of wildflowers and crops, like apples and cranberries. Named after the reddish patch on its back, the insect was listed as federally endangered in 2017.Experts estimated that numbers have declined by 87 percent in the last two decades. Before its population declined, rusty-patched bees were found in prairies, woodlands, farms, gardens and parks across the eastern U.S., the upper Midwest and parts of Canada.In a recent study publ ...read more
Researchers in Australia recently discovered a new species of demon catshark – a dusky deepwater shark with striking white eyes – by following a trail of some odd-looking eggs. Years ago, Brett Human, then a volunteer at the Western Australian Museum, came across an odd, yolk-yellow shark egg in the museum’s collection that had deep T-shaped ridges. Female catsharks incubate the eggs in their bodies for a while before sticking them to the sea floor, where they can take many months to hatch ...read more
Wild honeyguide birds and humans have hunted for honey together in Africa for centuries, if not longer. In some parts of the continent, the process starts when a hunter makes a loud, trilling “brr-hm” sound to attract the dull brown birds. They hop from tree to tree and chatter eagerly as they lead the honey hunter to a beehive in a baobab or other tree. After the human has looted the honey, the honeyguide dines on the beeswax left behind.A new study has found evidence that the famously reso ...read more
We’ve known about the colossal squid for nearly 150 years. Zoologist Japetus Steenstrup first reported on the species in 1857 after reading reports of it washing up on ocean shores. But there’s still a lot that we don’t know about it because it’s so hard to study. Its reproductive patterns, mating and hunting patterns are still largely unknown because we hardly ever see it in action. Nonetheless, ever since Twenty Thousand Leagues Under the Seas, we’ve been captivated by this supersiz ...read more
