One in six internet-using children from a survey of nearly 12,000 children in 12 countries across Asia and Africa are found to experience at least one form of technology-facilitated sexual exploitation and abuse, with many experiences undisclosed, according to research
From Australia's remote deserts to the surface of Mars, geological mapping underpins how we understand landscapes, natural resources, and the processes that shape our planet and others beyond it.
In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the gravitational energy of the weights into impulses that
Nearly 50 years ago, a puzzling earthquake beneath northern Utah jolted scientists' understanding of how Earth works. Now, research from the University of Utah confirms that the mysterious event was real, and part of a rare class of earthquakes occurring far deeper beneath the
Last week, OpenAI shocked the mathematical community by revealing that one of its internal artificial intelligence (AI) models had found a counterexample to a famous conjecture made by legendary Hungarian mathematician Paul Erdős in 1946.
As an expert on personality disorders, people often ask me about psychopathy. It seems everybody has had an ex, a boss, a neighbor or a relative who they suspect has traits of it. People are curious about how to recognize psychopathy, and whether it can explain certain harmful
Some plants are not the sitting ducks they appear to be when they come under attack. If a hungry caterpillar starts to chomp on the succulent leaves of a common bean plant, a highly sophisticated defense system kicks into action. The plant sends out a chemical distress signal

Honeycombs are famous for their elegant design, but now they may have found a new application: quantum computing. To collect knowledge from subatomic particles, quantum computers require carefully designed materials capable of performing necessary, complex functions. However,
About a billion years ago, Earth started to come into its own. It was past the awkwardness of its younger years full of growing pains and turmoil: comet strikes and slimy water, including the Great Oxidation Event that flipped the world upside down. Roughly a billion years ago,
Australian teens are experiencing high rates of intimate partner violence, one in 10 are relying on the withdrawal method for contraception and many don't know how to access help for their sexual health, according to the country's largest study of adolescents' sexual health and
Every summer, millions of people spray themselves with DEET to keep mosquitoes away. But new research suggests mosquitoes may be able to learn to associate the repellent with food—and even become attracted to it.
Their fur might feel the same, but a mink in the Everglades is not the same as a mink from northern Florida, researchers from the University of Connecticut and Central Connecticut State University report in the April 20 issue of Nature Heredity, which also ran a podcast
Pavlov’s dog, meet Pavlov’s mosquito The post Wearing DEET Might Be Like Ringing the Mosquito Dinner Bell appeared first on Nautilus .
Lab experiments suggest mosquitoes can smell DEET and learn to associate it with food, but it’s unclear whether that happens in the wild.
Some neuroscientists argue that the roots of experience lie deep inside the brain. If they’re right, the consciousness club will get a lot bigger
Scientists at the Department of Energy's Oak Ridge National Laboratory have developed a platform that engineers heat-loving microbes for industrial-scale manufacturing in a matter of weeks compared with previous approaches that can take months to years. This biotechnology tool
More than 1,000 years ago, Panama elites were buried together with translucent green stones long suspected to be emeralds. However, scientific analysis confirming the suspicion has never been conducted. Now, scientists have confirmed for the first time that these green gems
Weapons-grade plutonium can fuel nuclear reactors known as mixed oxide reactors, but none of these exist in the U.S.
On the moon, the lack of atmosphere and accompanying features such as biological activity, oxygen-rich air, flowing water and rain, wind, and most erosion allows the lunar regolith to preserve a long-term record of surface processes in the space environment.
When researchers survey wildlife in a lake, forest, or other habitat, they rarely capture every species present—some are simply too rare or elusive to detect. A new study published in the May issue of Ecological Informatics addresses this longstanding challenge by offering a
Over hundreds of years, increasingly sophisticated instruments have revealed — and continue to reveal — the secrets of our star. The post How We See the Beautiful, Violent Sun first appeared on Quanta Magazine
Scientists have solved the mystery of the Seychelles’ vanished crocodiles using DNA from historic museum specimens. The reptiles were not a unique species after all, but an isolated population of saltwater crocodiles that likely drifted thousands of kilometers across the Indian
Researchers in Spain have discovered that in collectives of moving fire ants, rippling "waves" of density and activity are likely triggered by local regions where ants collectively travel in the same direction as their neighbors.
Tire rubber contains antioxidant chemicals, most notably 6PPD and DPPD, that are released into the air as tiny particles during normal driving. A single compound formed from 6PPD, known as 6PPD-quinone was previously shown to be implicated in the death of coho salmon in urban
