Acoustic propulsion of nanomachines depends on their orientation
Microscopically tiny nanomachines which move like submarines with their own propulsion—for example in the human body, where they transport active agents and release them at a target: What sounds like science fiction has, over the past 20 years, bec.....»»
Social workers can help children more effectively by assessing the needs of the whole family, says study
What do children need most? The answer often depends on a person's relationship with the child......»»
Solar electric propulsion systems could be just what we need for efficient trips to Mars
There are many different ways to get to Mars, but there are always tradeoffs. Chemical propulsion, proven the most popular, can quickly get a spacecraft to the red planet. But they come at a high cost of bringing their fuel, thereby increasing the mi.....»»
A magnetically actuated acoustic metamaterial
Space coiling acoustic metamaterials are static and require manual reconfiguration for sound-field modulation. In a new report published in Communications Materials, Christabel Choi, and a team of scientists in computer science and engineering in the.....»»
Shape matters: Study finds microplastic fibers may travel as far as the stratosphere
How far microplastics travel in the atmosphere depends crucially on particle shape, according to a recent study by scientists at the University of Vienna and the Max Planck Institute for Dynamics and Self-Organization in Göttingen. Although spherica.....»»

Increase in rice farming in sub-Saharan Africa found to be producing rising amounts of methane
A team of engineers and atmospheric scientists at Harvard University, working with a colleague from the California Institute of Technology's Jet Propulsion Laboratory, has calculated the increased amount of methane being expelled into the atmosphere.....»»
ESA"s tiny pinhole thruster is ready for production
Rocket propulsion technology has progressed leaps and bounds since the first weaponized rockets of the Chinese and Mongolian empires. They were nothing more than rocket-powered arrows and spears but they set the foundations for our exploration of spa.....»»
New high-speed video system uses sensors, infrared illumination to track insects in large wild areas
Our ability to learn more about insect behavior—which affects ecology, health, and economy on a global scale—depends largely on suitable recording technology. But until now, these tools have been considerably limited......»»
A cat video highlighted a big year for lasers in space
NASA has invested more than $700 million in testing laser communications in space. Enlarge / Taters, the orange tabby cat of a Jet Propulsion Laboratory employee, stars in a video beamed from deep space by NASA's Psyche spacecraf.....»»
ESA is stockpiling simulated regolith for the ultimate lunar playground
Testing interplanetary landers means putting them in an environment as close to their destination as possible. Mars landers are often tested in the "Mars Yard" at NASA's Jet Propulsion Laboratory in South California, and now ESA is looking to build a.....»»
Image: Pinhole propulsion for satellites
A palm-sized propulsion option for future space missions: Each one of these seven emitter arrays etched onto this silicon wafer using micro- and nano-technology possesses more than 500 pinhole-sized emitters that spray out ions, accelerated via an el.....»»
