Phys.org / Instant digital rewards may make hard thinking feel less worthwhile
Imagine opening a difficult book in a quiet room. The first page is dense. You read one paragraph, then reread it. Nothing "clicks" yet. Your brain is doing what learning often requires: spending effort before the reward ...
Phys.org / Hidden role of garnet reveals how Earth's 660-km seismic boundary forms
Nearly 660 kilometers (410 miles) beneath Earth's surface lies one of the planet's most important internal boundaries. Known as the 660-km seismic discontinuity, it separates the mantle transition zone from the lower mantle ...
Tech Xplore / Giving drones a sense of 'pain' could help them predict instability before it happens
Imagine you're running and you sprain your ankle. The pain makes you gingerly limp the rest of the way home. This is a great example of how nature adapts to failures in a system. The pain tells you: "If you continue running ...
Phys.org / Himalayan pangolin emerges as distinct species, confirmed with DNA from 19th-century specimen
The pangolin is a midsize mammal found only in Africa and Asia. The pangolins' scales make them unique, but these scales have become their undoing. Pangolins are poached for their scales, making them the most highly trafficked ...
Medical Xpress / 'Polypill' for heart failure cuts hospitalizations and ER visits by 60% in trial
A "polypill" combining three medications recommended to treat heart failure into a single daily dose proved far more effective for patients than taking the drugs separately, a randomized clinical trial led by UT Southwestern ...
Phys.org / Quiet outings linked to more frequent dangerous wildlife encounters
The more people expand into previously natural areas, the more wildlife and humans step on each other's toes, leading to more interactions that may result in conflict. This includes national parks, where people flock to recuperate ...
Phys.org / Open cluster NGC 6134 in Norma is 1.38 billion years old and hosts a core, tidal tail and diffuse halo
Indonesian astronomers have conducted a comprehensive study of an open cluster in the constellation Norma, known as NGC 6134. Results of the new study, available in a research paper published June 23 on the preprint server ...
Phys.org / Quantum properties of multimode light observed despite extreme losses
Quantum properties of light are extremely delicate. When researchers attempt to measure them, even small losses on the way to a detector can make them invisible, limiting their use outside carefully controlled environments. ...
Phys.org / Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. ...
Phys.org / Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water ...
Medical Xpress / We can't entirely blame COVID vaccine mandates for lower vaccination rates today. It's not that simple
Childhood vaccination rates have slumped globally. In several countries, people are more hesitant about getting vaccinated. Populist political actors promote distrust of government and scientific institutions. And the disinformation ...
Science X / Carvings of shamans entering rock cracks may link to Siberian initiation rites
In the rugged landscapes of southern Siberia, rare images of shamans disappearing into the cracks of mountains can be found. Hundreds of years old and their artists long gone, their meaning remains a mystery. But perhaps ...
