Frogs use brains or camouflage to evade predators
Throughout evolution, prey animals have adopted a range of strategies to evade their predators. But often these elaborate strategies come at a cost. For example, looking out for and fleeing from predators involves a great deal of cognitive capacity a.....»»
Male glass frogs that care for offspring found to have smaller testes
A small international team of animal behavior researchers has found that species of glass frogs whose males help care for offspring tend to have smaller testes than species whose males do not help care for offspring. In their study, published in the.....»»
Killer instinct drove evolution of mammals" predatory ancestors, scientists suggest
The evolutionary success of the first large predators on land was driven by their need to improve as killers, researchers at the University of Bristol and the Open University suggest......»»
New method for marking neurotransmitter receptors in living animal brains
Researchers have developed a new method of labeling naïve neurotransmitter receptor proteins in living animal brains......»»
Baleen whales evolved a unique larynx to communicate but cannot escape human noise
Baleen whales are the largest animals to have ever roamed our planet and as top predators play a vital role in marine ecosystems. To communicate across vast distances and find each other, baleen whales depend critically on the production of sounds th.....»»
Unlocking the energetic secrets of collective animal movement: How group behavior reduces energy costs in fish
Many animals, including apex predators, move in groups. We know this collective behavior is fundamental to the animal's ability to move in complex environments, but less is known about what drives the behavior because many factors underlie its evolut.....»»
Roscosmos seeks to obscure bidding process to evade US sanctions
Historically closed bidding processes have been linked to corruption. Enlarge / Russian President Vladimir Putin (L) and Roscosmos Space Corporation Chief Yuri Borisov peruse an exhibit while visiting the Korolev Rocket and Space.....»»
Apple and Meta"s latest fight is over social media boosted post fees on iPhone
Meta's suggesting that users should purchase boosted posts outside of the App Store in order to avoid a 30% fee has drawn Apple's ire with it now accusing Meta of attempting to evade fees it knew was coming for over a year.Credit: MetaThere's been a.....»»
Ancient retroviruses played a key role in the evolution of vertebrate brains, suggest researchers
Researchers report in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains......»»
Researchers find having good neighbors and few top predators make predatory fish populations more resilient
A regime shift is gradually spreading through the archipelagos of the Swedish Baltic Sea coast, where shallow bays, previously dominated by pike and perch have one by one become dominated by one of their prey species, the three-spined stickleback......»»
Desert ants: Earth"s magnetic field calibrates their navigation system
They are only a few centimeters tall and their brains have a comparatively simple structure with less than 1 million neurons. Nevertheless, desert ants of the Cataglyphis genus possess abilities that distinguish them from many other creatures: The an.....»»
Examining the range of adulterants that disrupt the hormones of fish and amphibians
The contraceptive pill is obviously not intended for fish and frogs. However, the hormones in the pill and other pharmaceuticals that are not completely broken down in sewage treatment plants can affect aquatic organisms......»»
Drought may drive deadly amphibian disease, researchers find
Pumpkin toadlets are in trouble. Progressively severe droughts are disrupting the microbiomes of the thumbnail-sized orange frogs, potentially leaving them vulnerable to a deadly fungal disease, according to a new study by an international research t.....»»
General deep learning framework for emissivity engineering
Wavelength-selective thermal emitters (WS-TEs) have been frequently designed to achieve desired target emissivity spectra, as in typical emissivity engineering, for broad applications such as thermal camouflage, radiative cooling, and gas sensing, et.....»»
Whole-infrared-band camouflage with dual-band radiative heat dissipation
Camouflage refers to the ability to reduce the signal captured by detectors, thereby improving survival rates. However, the combination of detectors operating in multiple spectral bands poses a significant challenge, necessitating the development of.....»»
Apex predators not a quick fix for restoring ecosystems, 20-year study finds
A Colorado State University experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return—at least, not for a very long time......»»
New research describes how ADHD gives entrepreneurs an edge
The brains of people with ADHD function in ways that can benefit them as entrepreneurs, according to research from the West Virginia University John Chambers College of Business and Economics......»»
"Time to eat": Videos show that toe-tapping by frogs may be a strategy to draw out prey
It is well known that some species of frogs tap their posterior toes as they are seeking prey; this can be seen in many videos posted online. However, only a few studies to date have looked at the tapping habit itself, and not much is known about the.....»»
Scientists pinpoint growth of brain"s cerebellum as key to evolution of bird flight
Evolutionary biologists at Johns Hopkins Medicine report they have combined PET scans of modern pigeons along with studies of dinosaur fossils to help answer an enduring question in biology: How did the brains of birds evolve to enable them to fly?.....»»
130 poisonous frogs seized at Bogota airport
Authorities in Colombia seized 130 poisonous frogs being trafficked through the Bogota airport on Monday and arrested the Brazilian woman carrying them......»»
Invasive ants selectively abandon toxic baits, evading our most effective eradication method
Invasive ants are economically costly and ecologically devastating, and most of our eradication attempts have failed. Now, researchers at the University of Buenos Aires and the University of Regensburg have discovered that these ants can evade the mo.....»»
