‘Neural Lander’ uses AI to land drones smoothly

Drone (stock image). Credit: © Denis Rozhnovsky / Adobe Stock Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous…

Exotic matter uncovered in the sun’s atmosphere

Credit: © Peter Jurik / Adobe Stock Scientists from Ireland and France have announced a major new finding about how matter behaves in the extreme conditions of the Sun's atmosphere. The scientists used large radio telescopes and ultraviolet cameras on a NASA spacecraft to better understand the exotic but poorly understood "fourth…

Origami-inspired materials could soften the blow for reusable spacecraft

Origami shapes (stock image). Credit: © elettaria / Adobe Stock Space vehicles like SpaceX's Falcon 9 are designed to be reusable. But this means that, like Olympic gymnasts hoping for a gold medal, they have to stick their landings. Landing is stressful on a rocket's legs because they must handle the force from the impact…

Unexpected observation of ice at low temperature, high pressure questions water...

Ice crystals (stock image). Credit: © Images By Jefunne / Adobe Stock Through an experiment designed to create a super-cold state of water, scientists at the Department of Energy's Oak Ridge National Laboratory used neutron scattering to discover a pathway to the unexpected formation of dense, crystalline phases of ice thought to exist beyond Earth's…

Wind farms can only operate when there's a breeze, and solar power plants rely on sunlight. Researchers at EPFL are working on a method to capture an energy source that's constantly available at river…

Original kilogram replaced — new International System of Units (SI) entered...

Calibration weight (stock image). Credit: © djama / Adobe Stock In addition to Ampere, Kelvin, Mol and Co., the kilogram also is now defined by a natural constant. In concrete terms, this means that the original kilogram, which has been the measure of all things for 130 years, has now served its purpose in Paris.…

Big energy savings for tiny machines

Molecular model concept (stock image). Credit: © alice_photo / Adobe Stock Inside all of us are trillions of tiny molecular nanomachines that perform a variety of tasks necessary to keep us alive. In a ground-breaking study, a team led by SFU physics professor David Sivak demonstrated for the first time a strategy for manipulating these…

Artificial photosynthesis transforms carbon dioxide into liquefiable fuels

Carbon dioxide molecules illustration (stock image). Credit: © Ted Reinhard / Adobe Stock Chemists at the University of Illinois have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess CO2…

The researchers describe the technology in a study published today in Science…

Driverless cars working together can speed up traffic by 35%

Autonomous cars concept. Credit: © folienfeuer / Adobe Stock A fleet of driverless cars working together to keep traffic moving smoothly can improve overall traffic flow by at least 35 percent, researchers have shown. The researchers, from the University of Cambridge, programmed a small fleet of miniature robotic cars to drive on a multi-lane track…

‘Spider-like senses’ could help autonomous machines see better

Drones in city concept (stock image). Credit: © ChenPG / Adobe Stock What if drones and self-driving cars had the tingling "spidey senses" of Spider-Man? They might actually detect and avoid objects better, says Andres Arrieta, an assistant professor of mechanical engineering at Purdue University, because they would process sensory information faster. Better sensing capabilities…

Researchers unravel mechanisms that control cell size

Dividing cells illustration. Credit: © Kateryna_Kon / Adobe Stock Working with bacteria, a multidisciplinary team at the University of California San Diego has provided new insight into a longstanding question in science: What are the underlying mechanisms that control the size of cells? Nearly five years ago a team led by Suckjoon Jun, a biophysicist…

Ultra-clean fabrication platform produces nearly ideal 2D transistors

2D graphene illustration (stock image). Credit: © Ambelrip / Adobe Stock Semiconductors, which are the basic building blocks of transistors, microprocessors, lasers, and LEDs, have driven advances in computing, memory, communications, and lighting technologies since the mid-20th century. Recently discovered two-dimensional materials, which feature many superlative properties, have the potential to advance these technologies, but…

Wearable cooling and heating patch could serve as personal thermostat and...

Credit: © Liaurinko / Adobe Stock Engineers at the University of California San Diego have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go. The soft, stretchy patch cools or warms a user's skin to a comfortable temperature and keeps it there as…

Polymers jump through hoops on pathway to sustainable materials

Plastic recycling concept. Credit: © Andrey Popov / Adobe Stock Recyclable plastics that contain ring-shaped polymers may be a key to developing sustainable synthetic materials. Despite some promising advances, researchers said, a full understanding of how to processes ring polymers into practical materials remains elusive. In a new study, researchers identified a mechanism called "threading"…
