Polarization: From better sunglasses to a better way of looking at asteroid surfaces
Using the same principles that make polarized sunglasses possible, a team of researchers at the Arecibo Observatory in Puerto Rico have developed a technique that will help better defend against asteroids on a collision course with Earth......»»
NASA says goodbye to our planetary protector, the asteroid-spotting NEOWISE mission
Fifteen years after a launch that was intended to begin just a seven month mission, NASA's NEOWISE spacecraft has finally shut down......»»
Gaia spots possible moons around hundreds of asteroids
ESA's star-surveying Gaia mission has again proven to be a formidable asteroid explorer, spotting potential moons around more than 350 asteroids not known to have a companion......»»
NASA Retires Asteroid-Hunting Telescope

Scientists equip Australian sea lions with cameras to explore previously unmapped ocean habitats
What lies deep beneath ocean surfaces is often a mystery. In Australia, many underwater habitats have not been mapped, and researchers know little about them. Now, scientists are working to change that by employing sea lions as videographers......»»
New computer vision-based system monitors seasonal dynamics of tropical water
Understanding how water moves and changes around the world is more important than ever due to climate change, but monitoring inland water in the tropics is not easy. Most satellites are optical and simply take photos of surfaces. They cannot see thro.....»»
3D terrestrial laser scanner assists in reconstructing glacier"s mass balance sequence
Complex topography of glacier surfaces under accelerating global warming presents unprecedented challenges to traditional methods of glaciological observation due to intense fragmentation and differential melting......»»
Metallic nanosheets curl into nanovesicles
Inspired by the cell membrane structure, researchers, led by Dr. Xiaoqing Huang (State Key Laboratory of Physical Chemistry of Solid Surfaces, College of Chemistry and Chemical Engineering, Xiamen University) and Dr. Qi Shao (College of Chemistry and.....»»
Polarization and wavelength routers based on diffractive neural network
The concept of deep diffractive neural networks (D2NN) was introduced by Professor Ozcan's research team in 2018. D2NN combines the principles of light diffraction with the functionalities of neural networks. It consists of a series of continuous dif.....»»
Mass extinction 66 million years ago triggered rapid evolution of bird genomes, study finds
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began......»»
NASA smacked a spacecraft into an asteroid—and learned details about its 12-million-year history
NASA's DART mission—Double Asteroid Redirection Test—was humanity's first real-world planetary defense mission......»»
DART mission sheds new light on target binary asteroid system
In studying data collected from NASA's DART (Double Asteroid Redirection Test) mission, which in 2022 sent a spacecraft to intentionally collide with the asteroid moonlet Dimorphos, the mission's science team has discovered new information on the ori.....»»
Study finds most US voters agree on basic human values: So is polarization exaggerated?
The vast majority of American voters think alike on what they find important in life, but both Republicans and Democrats fail to recognize their shared views and values, according to new research from the Universities of Bath and Essex......»»
Inspired by cicada wings, researchers study the insects" antimicrobial properties to develop antibacterial surfaces
Trillions of periodical cicadas—several species of the genus Magicicada that emerge every 13 or 17 years—broke soil across the Eastern U.S. this summer. News outlets likened the event to Armageddon, an apocalypse or an invasion. But what about us.....»»
Trees reveal climate surprise: Microbes living in bark remove methane from the atmosphere
Tree bark surfaces play an important role in removing methane gas from the atmosphere, according to a study published 24 July in Nature......»»
Coalfire announces Cyber Security On-Demand portfolio
Coalfire announced its Cyber Security On-Demand portfolio to provide a flexible set of services that reduce cyber risks and remediate security vulnerabilities in customer environments. As attack surfaces grow, defenders need flexibility and a hacker.....»»

Introducing Ramses, ESA"s 2029 mission to asteroid Apophis
Thirty years ago, on 16 July 1994, astronomers watched in awe as the first of many pieces of the Shoemaker-Levy 9 comet slammed into Jupiter with incredible force. The event sparked intense interest in the field of planetary defense as people asked:.....»»
CISOs must shift from tactical defense to strategic leadership
Cyber threats are advancing quickly in size and sophistication, largely because of the rapid evolution of technology, increasing sophistication of cyber attackers, and the expansion of attack surfaces through interconnected systems and devices, accor.....»»
Signatures of life could survive near surfaces of the moons Enceladus and Europa, NASA experiment suggests
Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nu.....»»
Satellite to follow Empire State Building-sized asteroid as it zips by Earth
There’s a huge asteroid coming our way in 2029 and the European Space Agency (ESA) wants to track it every step of the way. Don’t worry, you can look up with confidence, as the 1,230-feet-long (about 375 meters) Apophis asteroid is not on a colli.....»»
