Among Gen Z, 79% want a job mainly focused on helping people or making a positive difference in others' lives. But only about half of workers ages 18–29 who want such a position say they have one.
Maybe to some degree. But a new international study suggests the communities we live in matter a whole lot, too. Researchers analyzed responses from 97,220 people across 66 countries and identified five broad factors associated with happier societies.
Researchers sequenced the genomes of three medaka, or Japanese rice fish, a common model organism used in biological research, nearly 10 and 20 years ago. While sequencing the genomes was relatively straightforward, assembling them was anything but.

A surprising number of creatures don’t benefit from greater intelligence The post The Virtue of Being Simple appeared first on Nautilus .
Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time inside. Researchers tested whether this was merely a misleading feature of the light pulse by making extremely weak measurements of the atoms. Surprisingly,
A new study of bonnethead sharks (Sphyrna tiburo) in Florida dispelled a previous hypothesis about how the distinctive head shapes of males and females develop, offering new insight into one of the species' most unusual biological traits.
The #MeToo movement began as a way for victims of gender-based violence to find solidarity, share their experiences and bring justice to perpetrators of misconduct. New research from the University of Kansas shows that conversations about #MeToo often become focused on
Shedd Aquarium has sent four zebra shark eggs to contribute to a conservation effort for the endangered species, marking the Chicago nonprofit's first delivery to Raja Ampat, Indonesia. As a founding partner of ReShark, Shedd Aquarium has long contributed expertise to the StAR
A rare fossil find shows a tooth embedded an ichthyosaur’s vertebra, where it was likely left when a giant pliosaurid chomped down on this dolphin-resembling reptile
DNA traces in the Shroud of Turin reveal a remarkable mixture of human lineages, microbes, plants, animals, and coral accumulated through centuries of handling and travel. The findings do not prove its age or authenticity, but they expose a hidden biological history preserved
Wildfires supercharged by drought and intense heat tore through the northwestern U.S. city of Spokane, forcing the evacuation of 65,000 people and reducing hundreds of buildings to cinders as firefighters raced Monday to contain the flames.
A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials. By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to
A centuries-old annual bird chick hunt on a remote Scottish island, known as the Guga Hunt, has been banned this year, authorities said Monday, citing conservation concerns.
Three lions from a Tokyo zoo have died from suspected heatstroke, and others are under treatment, a spokeswoman said Tuesday, with the big cats struggling with high humidity.
Nate Rouette and his brother Nelson went shark fishing on Cape Cod hoping for an exciting catch, but were shocked by what they reeled in—a tropical species of shark with a reputation for eating everything it can swallow.
Chemotherapy-surviving ovarian cancer cells may release fructose to help neighboring tumor cells loosen, escape, and spread. The discovery suggests that sugary diets and cholesterol-lowering drugs could influence cancer progression, though the effects have not yet been
Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss. This biological
Scientists have named a newly discovered beetle genus Luffy, inspired by the stretchy hero of the manga and anime One Piece. The insects have unusually long, slender mandibles, antennae, and mouthparts that resemble Luffy’s rubber-like ability to extend his body.
Taiwan’s steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs. After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84.1-meter (276-foot) tree, the tallest known in
The processes that capture carbon from the atmosphere and store it on the seabed are crucial for climate balance. However, assessing these mechanisms is often complicated because it requires measurements ranging from the surface to the deep ocean.
To turn abundant carbon dioxide into valuable fuel, we need a fast and efficient way to determine which catalysts work best over the longest time. AI models have the potential to help guide catalyst selection, but as with internet chatbots, AI models are only as good as the
