8216neural-lander8217-uses-ai-to-land-drones-smoothly

‘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…

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…

The extraordinary powers of bacteria visualized in real time

Bacterial cell culture (stock image). Credit: © sinhyu / Adobe Stock The global spread of antibiotic resistance is a major public health issue and a priority for international microbiology research. In his paper to be published in the journal Science, Christian Lesterlin, Inserm researcher at Lyon's "Molecular Microbiology and Structural Biochemistry" laboratory (CNRS/Université Claude Bernard…

Mites and ticks are close relatives, new research shows

Mite illustration. Credit: © peterschreiber.media / Adobe Stock Scientists from the University of Bristol and the Natural History Museum in London have reconstructed the evolutionary history of the chelicerates, the mega-diverse group of 110,000 arthropods that includes spiders, scorpions, mites and ticks. They found, for the first time, genomic evidence that mites and ticks do…

Did Leonardo da Vinci have ADHD?

Statue of Leonardo da Vinci. Credit: © ArTo / Adobe Stock Leonardo da Vinci produced some of the world's most iconic art, but historical accounts show that he struggled to complete his works. 500 years after his death, King's College London researcher Professor Marco Catani suggests the best explanation for Leonardo's inability to finish projects…

How to enhance or suppress memories

Erasing memories concept. Credit: © Andrea Danti / Adobe Stock What if scientists could manipulate your brain so that a traumatic memory lost its emotional power over your psyche? Steve Ramirez, a Boston University neuroscientist fascinated by memory, believes that a small structure in the brain could hold the keys to future therapeutic techniques for…

Oldest meteorite collection on Earth found in one of the driest places

Meteor illustration (stock image). Credit: © Vadimsadovski / Adobe Stock Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet's surface can be challenging, especially if you are interested in reconstructing how frequently they land. Now, researchers have uncovered a…

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

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…

Producing electricity at estuaries using light and osmosis

Example of an estuary, in Maine (stock image). Credit: © mandritoiu / Adobe Stock Most renewable power technologies are weather dependent. 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…

Plant stem cells require low oxygen levels

Arabidopsis (stock image). Credit: © Vasiliy Koval / Adobe Stock Plants function as the green lungs of our planet. Rightfully so, due to the capacity of a large single tree releasing more than 120 kg of oxygen into the Earth's atmosphere every year through a series of sunlight-fuelled reactions in photosynthesis. However during flood events,…
