Tech Xplore / Blame the model, not the machine—better data helps 3D-printed metamaterials match predictions
Additive manufacturing, such as 3D printing, provides an excellent opportunity to design metamaterials: materials with an engineered structure that leads to desired properties such as, for instance, resistance to vibrations. ...
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 / Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion
Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace ...
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 ...
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 / XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance ...
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 / Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
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 ...
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. ...
Medical Xpress / Two studies point to beta cells as active players in type 1 diabetes
Type 1 diabetes is widely understood as an autoimmune disease, with the immune system attacking the insulin-producing beta cells of the pancreas. But two new studies suggest those cells may be more than passive victims. Together, ...
Phys.org / Compromise drives shared risky decisions, but biased blame and credit can break teamwork
Relationships are all about compromise. From deciding on where to eat dinner with a friend to negotiating chore lists at home, we often experience situations that require some flexibility. But what happens when we must work ...
