Celibacy: Its surprising evolutionary advantages
Why would someone join an institution that removed the option of family life and required them to be celibate? Reproduction, after all, is at the very heart of the evolution that shaped us. Yet many religious institutions around the world require exa.....»»
Long-tailed macaques react with disappointment when their expectations are not met: Evolutionary insights into fairness
A sense of fairness has long been considered purely human—but animals also react with frustration when they are treated unequally by a person. For instance, a well-known video shows monkeys throwing the offered cucumber at their trainer when a cons.....»»
Researchers find evolutionary selection for traits associated with immunity, metabolism in Tsimane and Moseten genomes
A team of global experts has discovered new signals of natural selection in humans......»»
Tesla Model 3 maintenance costs: What can you expect?
The Tesla Model 3 is one of the most popular electric cars out there, and one of its advantages is how cheap it is to maintain. But just how cheap is it?.....»»
Better metric for prioritizing conservation of "evolutionarily distinctive" species
An updated metric for prioritizing species' conservation that incorporates scientific uncertainty and complementarity between species, in addition to extinction risk and evolutionary distinctiveness, has been published on February 28 in the open acce.....»»
Shark from the Jurassic period was already highly evolved
Cartilaginous fish have changed much more in the course of their evolutionary history than previously believed. Evidence for this thesis has been provided by new fossils of a ray-like shark, Protospinax annectans, which demonstrate that sharks were a.....»»
Findings provide insights into the surprising evolution of proteins
A team of researchers from the Faculty of Science at Charles University, BIOCEV and IOCB (Czech Republic), Johns Hopkins University (U.S.) and ELSI (Japan) has discovered why modern proteins use a quasi-universal repertoire of 20 canonical amino acid.....»»
Reconstructing the evolutionary history of detoxifying enzymes
Our body produces lots of enzymes that break down toxic substances. One class of such enzymes are the flavin-containing monooxygenases (FMOs), which are present in all tetrapods. Humans have five different FMO genes, of which the first four display t.....»»
Webb spots surprisingly massive galaxies in early universe
The James Webb Space Telescope has spotted six massive galaxies that emerged not long after the Big Bang, a study said Wednesday, surprising scientists by forming at a speed that contradicts our current understanding of the universe......»»

Deep learning enhanced NIR-II volumetric imaging of whole mice vasculature
In vivo small animal fluorescence imaging is widely used in oncology, drugs, antibodies, nanomaterials, inflammation, immune diseases, gene therapy, apoptosis, and other research fields because of its advantages such as in vivo real-time imaging obse.....»»
Reproductive strategy of deep-sea worms provides clues to evolutionary mystery
Deep on the ocean floor, strange worm-like creatures can be found, the evolution of which has long perplexed scientists. Now, in a recently published study, researchers from Japan have observed an interesting mode of reproduction, which could shed li.....»»
Protecting hydroponics from electrochemical hypochlorination damage
Closed loop hydroponics, where nutrient solution drainage is captured and reapplied to the crop, offers advantages over flow-through or single pass systems by way of water and nutrient resource use efficiency. Increasing resource use efficiency reduc.....»»
Neighborly cooperation can ensure your genes survive, new research finds
Cooperating with your neighbors, especially if they are distant relatives, can be an effective evolutionary strategy, new research has found......»»
How midgut development in insects reveals their evolutionary past
Insects have been around for millions of years, but their evolutionary relationships are still not fully known. Now, researchers from Japan have discovered that an old insect lineage can contribute to a clearer picture of their past......»»
Dead kangaroos make a surprising feast for possums in the Australian Alps
Vultures, hyenas, and Tasmanian devils are highly efficient scavengers, able to locate and consume carrion rapidly, including the meat and bones......»»

Evolutionary geneticists and forensic experts who have spent years analyzing the remains of Chilean poet and Nobel laureate Pablo Neruda have added important new information to the case regarding a possible covert assassination......»»
Grassroots effort champions inclusive language in science
A new grassroots effort—announced this month in Trends in Ecology and Evolution—is calling for a reevaluation of some terminology used in ecology and evolutionary biology (EEB) to make it more inclusive and precise......»»
Study reveals biodiversity engine for fishes: Shifting water depth
Fish, the most biodiverse vertebrates in the animal kingdom, present evolutionary biologists a conundrum: The greatest species richness is found in the world's tropical waters, yet the fish groups that generate new species most rapidly inhabit colder.....»»
Psychopaths: why they"ve thrived through evolutionary history—and how that may change
When you start to notice them, psychopaths seem to be everywhere. This is especially true of people in powerful places. By one estimate, as many as 20% of business leaders have "clinically relevant levels" of psychopathic tendencies—despite the fac.....»»
