A mosquito proboscis repurposed as a 3-D printing nozzle can print filaments around 20 micrometers wide, half the width of a fine human hair.
In the aftermath of slavery, white psychiatrists diagnosed Black people with “religious excitement” and claimed they were unfit for freedom.
Fossils from Qatar have revealed a small, newly identified sea cow species that lived in the Arabian Gulf more than 20 million years ago. The site contains the densest known collection of fossil sea cow bones, showing that these animals once thrived in rich seagrass meadows. Their ecological role mirrors that of modern dugongs, which still reshape the Gulf’s seafloor as they graze. The findings may help researchers understand how seagrass ecosystems respond to long-term environmental change.

When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, scientists say.
White-sided dolphins seem to help killer whales "scout" and catch Chinook salmon near Vancouver Island, then eat the leftovers
The tiny pantheon known as the Asgard archaea bear traits that hint at how plants, animals and fungi emerged on Earth.
Biologists poured cold water on Colossal Biosciences’ claim to have brought the dire wolf back from extinction, and some worry the overblown headlines will undermine conservation work
Scientist and photographer Felice Frankel has zoomed in on everyday occurrences with her camera for her new book, Phenomenal Moments, which reveals the hidden science in our daily lives
Finding that vampire bats along Peru’s coast carried H5N1 antibodies raises concerns that multiple bat species could become reservoirs for the virus.
The rollout of a type of genetic technology called a gene drive for tackling malaria could be edging closer after a lab study supports its success
Archaeologists found flint, iron pyrite to strike it and sediments where a fire was probably built several times at an ancient site in England.
A compilation of 100 examples of biological tilings shows how repeated natural motifs enhance strength, flexibility and other key functions.
Skin fossils from a sauropod dinosaur examined with an electron microscope feature structures called melanosomes, which are similar to those that create the bright colours in birds' feathers
The finding could guide beekeepers to keep hives out of most vulnerable areas of the Irish heathlands.
A peer-reviewed paper about Chinese startup DeepSeek's models explains their training approach but not how they work through intermediate steps.
Irritability is a normal response to frustrations, but it can sometimes signal an underlying mental health disorder, like depression or anxiety.
Researchers uncovered rare azurite traces on a Final Paleolithic artifact, overturning assumptions that early Europeans used only red and black pigments. The find suggests ancient people possessed deeper knowledge of minerals and colors than believed. It also hints at vanished forms of decoration or artistic practices. The discovery opens new avenues for exploring identity and symbolism in Ice Age cultures.
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.
