Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres -- between 50 to 500 microns -- that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque.
Scientists have discovered that bacterial populations remain stable on factory floor despite cleaning efforts in ready-to-eat food production facilities.
As any surfer will tell you, waves pack a powerful punch. Now, we are one step closer to capturing the energy behind the ocean's constant ebb and flow with an improved 'blue energy' harvesting device. Researchers report that simply repositioning the electrode -- from the center of a see-sawing liquid-filled tube to the end where the water crashes with the most force -- dramatically increased the amount of wave energy that could be harvested.
Kerala University researchers unearth crucial evidence that sheds light on Early Harappan settlement in collaborative project
White House directs NASA to establish Coordinated Lunar Time for moon missions amid international space race
How big is India’s private space sector? How is the Centre promoting it? What laws and schemes govern it? What is ISRO’s role in it?
The most powerful jets in the universe come from the biggest black holes at the centres of galaxies.
For most people, the determination of which hand is dominant may come down to chance
One of the main goals of such a powerful scanner is to refine our understanding of the anatomy of the brain
Psychology, behavioural economics, public policy, and many other fields owe a great debt to his and Amos Tversky’s work
Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were moving apart. The researchers think that the unexpected signature could be explained by the mechanics of underlying tectonic plates that hasn't yet been described in other models.
One of the great mysteries of modern science is dark matter. We know dark matter exists thanks to its effects on other objects in the cosmos, but we have never been able to directly see it. And it s no minor thing currently, scientists think it makes up about 85% of all the mass in the universe.
Study reveals that newly hatched chicks can instantly recognize objects with their vision, even if they've only ever experienced them by touch.
There is room for just one small bottle in the world's first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype is groundbreaking: it shows that elastocalorics is becoming a viable solution for practical applications. This climate-friendly cooling and heating technology is far more energy-efficient and sustainable than current methods.
A new data crowdsourcing platform aims to preserve the sound of Romeyka, an endangered millennia-old variety of Greek. Experts consider the language to be a linguistic goldmine and a living bridge to the ancient world.
Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.
Adolescents with high positive affect may have improved physical and mental health as adults, according to a new study.
Emory environmentals scientist combined field-level data with machine-learning techniques to estimate soil organic carbon at the U.S. scale, another step toward providing more accurate baseline data to improve Earth system models for climate change.
An international team of scientists published a study emphasizing the urgent need to align political will, economic resources, and societal values to ensure a more sustainable and equitable world. The review summarizes the grave threats facing the planet but rejects a 'doom and gloom' philosophy. They advocate a global cultural shift that elevates kinship with nature and communal well-being, underpinned by the recognition of Earth's finite resources and the interconnectedness of its inhabitants.
