CNN —Same-sex sexual behavior has been observed in more than 1,500 animal species, but a new study has found that it is massively underreported by researchers. Observations of this same-sex behavior in animals, such as sexual mounting and genital touching, date back to the 1700s and 1800s. In a study published Thursday in the journal PLOSOne, a team of researchers at the University of Toronto, Northwestern University and the University of Warsaw found that experts who study animal behavior are underreporting and rarely publishing their observations of same-sex sexual behavior. The study surveyed 65 experts and found that 77% of them observed same-sex sexual behaviors in the species they studied. Davis added that there have been other obstacles that get in the way of documenting same-sex behaviors among animals.

The research firms both raised their Apple price target to $240, representing potential upside of 14%. Both CFRA and Bernstein increased their Apple price target to $240 per share on Friday. According to CFRA analyst Angelo Zino, who previously had a $210 price target, Apple is poised to turn the iPhone into "the ultimate personal assistant." "We expect Apple Intelligence (AI) to help support incremental consumer upgrades, driven by loyalists and an aging installed base, with AI being more evolutionary than cyclical that will aid multiple years of growth," Zino said. Bernstein bases its $240 price target on fiscal year 2025 earnings per share of $8.00 and a historically high multiple of 30x earnings.

☆ Scientists finally think they know why giraffe necks are so long
▼ + stars: | 2024-06-17 | by ( Jessica Orwig | ) www.businessinsider.com time to read: +6 min

In the 19th century, Charles Darwin and Jean Baptiste Lamarck suggested that giraffes evolved long necks to help them snatch leaves on trees. A later theory usurped Darwin and Lamarck's, suggesting that male giraffes evolved long necks to fight and compete for female mates. "I realized that the important question was, 'Do males have proportionally longer necks compared to the rest of their body?'" Cavener said this may be the first study to suggest that females, not males, are the reason for giraffes' long necks. That's important not only for understanding giraffe evolution but how male and female giraffes behave differently, which could help with conservation efforts.

But the impact of ancient DNA, which has revolutionized archaeology in Europe and higher latitudes, has been more limited in tropical areas because DNA degrades more easily in warm conditions. However, recent advances in ancient DNA technology are expanding its reach, she said. And suddenly, we now have the ability to do these large-scale genomic studies and apply ancient DNA as a tool to help us understand the past in Mesoamerica,” Warinner said.

☆ 4 theories to help explain why you dream: 'The dreaming brain is as active as the waking brain,' neuroscientist says

"We now know all consciousness is powered by electricity, including dreaming, and it turns out the dreaming brain is as active as the waking brain – sometimes even more so," he said. "In this theory, dreams are like a virtual simulation where we can test different responses and imagine the consequences," he said. Brain functionalityA straightforward theory about why we dream is that dreaming can be good for "keeping the brain tuned and ready even during sleep." In other words, the processes that the brain experiences as you're dreaming may be helpful for brain functionality and keeping your brain sharp. But adrenaline is still present while you're sleeping; think about how your heart can race when you're dreaming about being chased.

All humans have at least a little Neanderthal DNA, a 2020 study found. AdvertisementThen, around 75,000 years ago, Neanderthals were living in Asia and Europe when some humans started moving out of Africa. To figure out when our ancient human ancestors hooked up with Neanderthals, the researchers compared stretches of Neanderthal DNA in their genomes. For example, the researchers found both current and ancient humans have Neanderthal genes that affect metabolism, immunity, and skin pigmentation. They speculate that these characteristics may have benefited ancient humans who inherited them and then kept passing them on.

How did the ghoulish creatures known as anglerfish pull off the evolutionary feat that let them essentially take over the ocean’s sunless depths? It took peculiar sex — extremely peculiar sex. Scientists at Yale University have discovered that a burst of anglerfish diversification began some 50 million years ago as the ancestral line developed a bizarre strategy to ensure successful reproduction in the dark wilderness. To mate, tiny males would clamp with sharp teeth onto the bellies of much larger females. Some males would let go after mating while others would permanently fuse into the females.

The nocturnal critter was most likely a German cockroach, and its ancestors were pestering people more than 2,000 years ago in southern Asia, a new study found. German cockroaches, scientifically known as Blattella germanica, are ubiquitous in cities in the United States and around the world. The research team received 281 German cockroach samples from 57 sites in 17 countries and studied their DNA to trace their evolution. And we know that transatlantic trade routes probably were the culprit for the spread of German cockroaches. “For example, the German cockroach has insecticide resistance that is not detected in many other pests,” he said.

New research this week is adding fresh detail to one of paleontology’s biggest questions: Did dinosaur blood run hot or cold? Clues from fossilized eggshells and bones have now suggested that some dinosaurs were warm-blooded and others were not. Reinhard Dirscherl/ullstein bild/Getty ImagesMarine scientists have used artificial intelligence to decode previously unknown complexity in the calls of sperm whales. The whales produced a catalog of clicking sounds, which the researchers described as akin to a “phonetic alphabet” for sperm whales. What sperm whales are saying with their clicks remains a mystery to human ears, but understanding the scope of their vocal exchanges is an important step toward linking their calls with specific behavior.

It takes a lot of energy to grow a baby — just ask anyone who has been pregnant. In a study published on Thursday in the journal Science, Australian researchers estimated that a human pregnancy demands almost 50,000 dietary calories over the course of nine months. That’s the equivalent of about 50 pints of Ben and Jerry’s Cherry Garcia ice cream, and significantly more than the researchers expected. Previous estimates were lower because scientists generally assumed that most of the energy involved in reproduction wound up stored in the fetus, which is relatively small. But Dustin Marshall, an evolutionary biologist at Monash University, and his students have discovered that the energy stored in a human baby’s tissues accounts for only about 4 percent of the total energy costs of pregnancy.

They believe it was caused by a neighboring male in what's known as a "long call battle," Laumer told Business Insider. Adult male orangutans like Rakus shout out "long calls" to attract females and let rival males know that this is their territory. Rakus may have unintentionally touched his leaf-mush-covered finger to his face, and instantly felt the pain-relieving properties of the plant, Laumer explained. But, because this is the first time this behavior has ever been observed in orangutans, scientists can't say for sure why or how Rakus did it. More alike than we are differentRakus's behavior reminds us a lot of our own behavior with medicinal plants, which could help us understand where our knack for medicinal treatment first evolved.

CNN —What did people in the Stone Age eat before the advent of farming around 10,000 years ago? Scientists analyzed chemical signatures preserved in bones and teeth belonging to at least seven different Iberomaurusians and found that plants, not meat, were their primary source of dietary protein. The evidence suggested that the Iberomaurusians consumed “fermentable starchy plants” such as wild cereals or acorns, according to the study. The work undermines the idea that a Stone Age diet was meat heavy — a rigid assumption perpetuated by present-day dietary trends like the Paleo diet. The transition to agriculture was a complex process that occurred at different times and proceeded at different rates, in different ways with different foods, in different places, Pobiner said.
