Scientific research on altruism in animals; bullying, anti-predator behavior, weird eating and mating habits and more. en-us Mon, 09 Mar 2026 00:50:13 EDT Mon, 09 Mar 2026 00:50:13 EDT 60 https://www.sciencedaily.com/images/scidaily-logo-rss.png https://www.sciencedaily.com/news/plants_animals/behavior/ For more science news, visit ScienceDaily. https://www.sciencedaily.com/releases/2026/03/260304184224.htm A sweeping new study of more than 2,000 insect species reveals a troubling reality: many insects may be far less capable of coping with rising temperatures than scientists once hoped. Researchers found that while some species living at higher altitudes can temporarily boost their heat tolerance, many insects in tropical lowlands—where biodiversity is highest—lack this flexibility. Because insects play essential roles as pollinators, decomposers, and predators, their vulnerability could ripple through entire ecosystems.

Researchers in Japan found that macaques who regularly bathe show subtle but intriguing differences in lice patterns and gut bacteria compared to those who stay dry. Surprisingly, sharing the hot pools didn’t increase their parasite load, challenging assumptions about disease risk.

After tracking nearly a decade of GPS data and thousands of kill sites, researchers found that wolves often muscle in on cougar kills—sometimes even killing the cats—but cougars never return the favor. Instead of fighting back, cougars adapt. As elk numbers dropped, they shifted toward hunting more deer, which they can eat quickly and in safer terrain, helping them dodge wolf encounters.

Paleontologists have discovered the southernmost remains ever found of Purgatorius—the earliest-known relative of all primates, including humans—in Colorado’s Denver Basin. Previously thought to be confined to Montana and parts of Canada, this shrew-sized, tree-dwelling mammal now appears to have spread southward soon after the asteroid impact that wiped out the dinosaurs. Tue, 03 Mar 2026 05:06:19 EST https://www.sciencedaily.com/releases/2026/03/260303050619.htm https://www.sciencedaily.com/releases/2026/02/260228082717.htm Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in a coordinated way throughout the body. About a quarter of cell types change in number over time, and many of these shifts differ between males and females. The research also highlights shared genetic “hotspots” that could become targets for anti-aging therapies.

Scientists found that active ingredients from isoxazoline treatments pass into pet feces, exposing dung-feeding insects to toxic chemicals. These insects are essential for nutrient cycling and soil health. The findings suggest everyday pet treatments could ripple through ecosystems in surprising ways. Sun, 22 Feb 2026 01:24:32 EST https://www.sciencedaily.com/releases/2026/02/260221000328.htm https://www.sciencedaily.com/releases/2026/02/260212234214.htm Even Antarctica’s toughest native insect can’t escape the reach of plastic pollution. Scientists have discovered that Belgica antarctica — a tiny, rice-sized midge and the southernmost insect on Earth — is already ingesting microplastics in the wild. While lab tests showed the hardy larvae can survive short-term exposure without obvious harm, those exposed to higher plastic levels had reduced fat reserves, hinting at hidden energy costs. Mon, 16 Feb 2026 07:48:45 EST https://www.sciencedaily.com/releases/2026/02/260212234214.htm https://www.sciencedaily.com/releases/2026/02/260212025612.htm A new scientific review challenges the headline-grabbing claim that Yellowstone’s returning wolves triggered one of the strongest trophic cascades on Earth. Researchers found that the reported 1,500% surge in willow growth was based on circular calculations and questionable comparisons. After correcting for modeling and sampling flaws, the supposed ecosystem-wide boom largely disappears. Thu, 12 Feb 2026 08:51:03 EST https://www.sciencedaily.com/releases/2026/02/260212025612.htm https://www.sciencedaily.com/releases/2026/02/260210231546.htm Hundreds of millions of years ago, the first animals to crawl onto land were strict meat-eaters, even as plants had already taken over the landscape. Now scientists have uncovered a 307-million-year-old fossil that rewrites that story: one of the earliest known land vertebrates to start eating plants. The animal, named Tyrannoroter heberti, was a stocky, football-sized creature with a skull packed with specialized teeth designed for crushing and grinding vegetation. Wed, 11 Feb 2026 03:19:21 EST https://www.sciencedaily.com/releases/2026/02/260210231546.htm https://www.sciencedaily.com/releases/2026/02/260208233836.htm Forests around the world are quietly transforming, and not for the better. A massive global analysis of more than 31,000 tree species reveals that forests are becoming more uniform, increasingly dominated by fast-growing “sprinter” trees, while slow-growing, long-lived species are disappearing. These slower species act as the backbone of forest ecosystems, storing carbon, stabilizing environments, and supporting rich webs of life—especially in tropical regions where biodiversity is highest. Mon, 09 Feb 2026 02:17:56 EST https://www.sciencedaily.com/releases/2026/02/260208233836.htm https://www.sciencedaily.com/releases/2026/01/260131082418.htm Termites did not evolve complex societies by adding new genetic features. Instead, scientists found that they became more social by shedding genes tied to competition and independence. A shift to monogamy removed the need for sperm competition, while food sharing shaped who became workers or future kings and queens. Together, these changes helped termites build colonies that can number in the millions. Sat, 31 Jan 2026 08:35:05 EST https://www.sciencedaily.com/releases/2026/01/260131082418.htm https://www.sciencedaily.com/releases/2026/01/260122074035.htm A new study suggests humans belong in an elite “league of monogamy,” ranking closer to beavers and meerkats than to chimpanzees. By comparing full and half siblings across species and human cultures, researchers found that long-term pair bonding is unusually common in our species. Even societies that permit polygamy show far more monogamy than most mammals. This rare evolutionary shift may have played a key role in human social success. Thu, 22 Jan 2026 23:58:52 EST https://www.sciencedaily.com/releases/2026/01/260122074035.htm https://www.sciencedaily.com/releases/2026/01/260115022814.htm A large international study reveals that mammals tend to live longer when reproduction is suppressed. On average, lifespan increases by about 10 percent, though the reasons differ for males and females. Castrated males avoid the harmful effects of testosterone, while females gain longevity by sidestepping the intense physical demands of pregnancy and nursing. The results underscore a powerful biological trade-off between making offspring and staying alive longer. Fri, 16 Jan 2026 01:05:13 EST https://www.sciencedaily.com/releases/2026/01/260115022814.htm https://www.sciencedaily.com/releases/2025/12/251226045324.htm Environmental change doesn’t affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. Two populations facing different kinds of change can end up on completely different evolutionary paths. The findings challenge the idea that one population’s response can represent a whole species. Tue, 30 Dec 2025 15:57:09 EST https://www.sciencedaily.com/releases/2025/12/251226045324.htm https://www.sciencedaily.com/releases/2025/12/251222080127.htm Some ants thrive by choosing numbers over strength. Instead of heavily protecting each worker, they invest fewer resources in individual armor and produce far more ants. Larger colonies then compensate with collective behaviors like group defense and coordinated foraging. The strategy has been linked to evolutionary success and greater species diversity. Mon, 22 Dec 2025 08:49:12 EST https://www.sciencedaily.com/releases/2025/12/251222080127.htm https://www.sciencedaily.com/releases/2025/12/251218060552.htm Researchers announced over 70 new species in a single year, including bizarre insects, ancient dinosaurs, rare mammals, and deep-river fish. Many were found not in the wild, but in museum collections, proving that major discoveries can still be hiding in plain sight. Fri, 19 Dec 2025 05:59:30 EST https://www.sciencedaily.com/releases/2025/12/251218060552.htm https://www.sciencedaily.com/releases/2025/12/251210092029.htm Scientists tracking young Arizona Bald Eagles found that many migrate north during summer and fall, bucking the traditional southbound pattern of most birds. Their routes rely heavily on historic stopover lakes and rivers, and often extend deep into Canada. As the eagles mature, their flights become more precise, but they also encounter significant dangers like electrocution and poisoning. These discoveries point to the need for targeted conservation of critical travel corridors. Thu, 11 Dec 2025 09:32:06 EST https://www.sciencedaily.com/releases/2025/12/251210092029.htm https://www.sciencedaily.com/releases/2025/12/251209043042.htm Humans don’t just recognize each other’s voices—our brains also light up for the calls of chimpanzees, hinting at ancient communication roots shared with our closest primate relatives. Researchers found a specialized region in the auditory cortex that reacts distinctly to chimp vocalizations, but not to those of bonobos or macaques, revealing an unexpected mix of evolutionary and acoustic influences. Wed, 10 Dec 2025 01:45:47 EST https://www.sciencedaily.com/releases/2025/12/251209043042.htm https://www.sciencedaily.com/releases/2025/12/251208052529.htm Ancient pterosaurs may have taken to the skies far earlier and more explosively than birds, evolving flight at their very origin despite having relatively small brains. Using advanced CT imaging, scientists reconstructed the brain cavities of pterosaur fossils and their close relatives, uncovering surprising clues—such as enlarged optic lobes—that hint at a rapid leap into powered flight. Their findings contrast sharply with the slow, stepwise evolution seen in birds, whose brains expanded over time to support flying. Tue, 09 Dec 2025 03:06:41 EST https://www.sciencedaily.com/releases/2025/12/251208052529.htm https://www.sciencedaily.com/releases/2025/12/251208052518.htm Researchers revealed that the microbial metabolite TMA can directly block the immune protein IRAK4, reducing inflammation and improving insulin sensitivity. The molecule counteracts damage caused by high-fat diets and even protects mice from sepsis. Since IRAK4 is a known drug target, this pathway could inspire new diabetes therapies. The study highlights how gut microbes and nutrition can work together to support metabolic health.

This signal prompts worker ants to open the pupae’s cocoons and disinfect them with formic acid, stopping the infection before it can spread. Although the treatment kills the sick pupa, it protects the colony and helps ensure its long-term survival. Researchers found that only pupae too sick to recover send this scent, showing just how finely tuned the colony’s early-warning system is. Wed, 03 Dec 2025 01:02:05 EST https://www.sciencedaily.com/releases/2025/12/251203010205.htm https://www.sciencedaily.com/releases/2025/11/251130205418.htm Chimpanzees naturally ingest surprising amounts of alcohol from ripe, fermenting fruit. Careful measurements show that their typical fruit diet can equal one to two human drinks each day. This supports the idea that alcohol exposure is not a modern human invention but an ancient primate habit. The work strengthens the “drunken monkey” hypothesis and opens new questions about how animals use ethanol cues in their environment.

Their analysis points to great apes and even Neanderthals sharing forms of kissing millions of years ago. The behavior appears to have persisted through evolution as a social or bonding tool. Yet its patchy presence across human cultures hints at a mix of biology and cultural invention.

When overactivated, the gene makes worms oddly indifferent to danger and food, suggesting trade-offs between lifespan and behavior. The work highlights how deeply intertwined the brain, metabolism, and environment are. These pathways may eventually be targeted to extend life without extreme dieting.
