Model suggests some asteroids that come close to Earth are torn apart by its gravity
A pair of astronomers, one with Luleå University of Technology's Asteroid Engineering Laboratory, in Finland, the other with the Southwest Research Institute, in the U.S., has found via computer simulation, that some large asteroids that come close.....»»
Scientists chart diversity, function and activity of global supraglacial DNA viruses
Supraglacial environments mainly consist of four main types of habitats for microbes and viruses, including snow, ice, meltwater and cryoconites (the granular sediment on glacier surfaces). A new paper published in Science Bulletin reveals that there.....»»
Oral peptides: A new era in drug development
For decades, a substantial number of proteins, vital for treating various diseases, have remained elusive to oral drug therapy. Traditional small molecules often struggle to bind to proteins with flat surfaces or require specificity for particular pr.....»»
Miniaturized jumping robots could study an asteroid"s gravity
Missions focusing on small bodies in the solar system have been coming thick and fast lately. OSIRIS-Rex, Psyche, and Rosetta are all examples of projects that planned or did rendezvous with a small body in the solar system. But one of their biggest.....»»
Harnessing all-dielectric metamaterials to manipulate the polarization state of light
Polarization is one of the fundamental characteristics of electromagnetic waves. It can convey valuable vector information in sensitive measurements and signal transmission, which is a promising technology for various fields such as environmental mon.....»»
From the moon"s south pole to an ice-covered ocean world, several exciting space missions are slated for launch in 2024
The year 2023 proved to be an important one for space missions, with NASA's OSIRIS-REx mission returning a sample from an asteroid and India's Chandrayaan-3 mission exploring the lunar south pole, and 2024 is shaping up to be another exciting year fo.....»»
NASA asteroid sampling mission renamed OSIRIS-APEX for new journey
The former OSIRIS-REx spacecraft sets off on a journey to study asteroid Apophis and take advantage of the asteroid's 2029 flyby of Earth, the likes of which hasn't happened since the dawn of recorded history......»»
Analysis finds that organic compounds in asteroids likely formed in colder regions of space
Analysis of organic compounds—called polycyclic aromatic hydrocarbons (PAHs)—extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas of space between stars rather than in hot regions n.....»»
New nuclear deflection simulations advance planetary defense against asteroid threats
Researchers at Lawrence Livermore National Laboratory (LLNL) have developed a modeling tool for assessing the potential use of a nuclear device to defend the planet against catastrophic asteroid impacts......»»
Hera"s solar wings are cleared for flight
The solar wings that will power ESA's Hera asteroid mission for planetary defense as it ventures out to meet the Dimorphos asteroid have been cleared for flight. As part of its current test campaign at ESA's ESTEC Test Center in the Netherlands, the.....»»
Ensuring proof of origin through marker-free tracing of logs
Until now, reliably tracing logs to their origin has been difficult to achieve. Researchers at Fraunhofer IPM and their partners have now shown that logs and trunk sections can be identified based on the structure of the cut surfaces. The recent rese.....»»
Possible first ever synchrotron-based analysis of asteroid Bennu to be performed
After an amazing journey, a grain from the asteroid Bennu will be brought to Diamond Light Source, the UK's national synchrotron, for scientific measurements. The grain is from 100 milligrams of sample sent to the Natual History Museum (NHM) in Londo.....»»
Our cities will need to harvest stormwater in an affordable and green way—here"s how
When it rains, stormwater runs down surfaces like streets and parking lots and into drains. Most of the time, we see it as a problem because it can cause floods. Recent storms across eastern Australia created huge amounts of stormwater and flooding......»»
Q&A: Polarization in the Netherlands actually is not that bad
Discussions about important societal issues, whether they relate to domestic or foreign affairs, on the street and in academia, seem to be intensifying. The heightened tone, personal attacks, and polarization are characteristic of these discussions......»»
The great diversity of fish mouths: Catfish attach differently than expected
Some may know suckermouth armored catfish as "window cleaners" from aquariums because they possess a suckermouth, which allows them to attach to various surfaces. The attachment is not only enabled by a vacuum created by the fish but also by specific.....»»
NASA’s Psyche spacecraft sends back its first image of a star field
NASA has shared the first images taken by its Psyche mission, which launched in October to study a strange metal asteroid located in the main belt......»»
Asteroid will pass in front of bright star Betelgeuse to produce a rare eclipse visible to millions
One of the biggest and brightest stars in the night sky will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse......»»
Alert fatigue puts pressure on security and development teams
Security practitioners are under a tremendous amount of pressure to secure today’s applications, according to Cycode. The research found that AppSec chaos reigns, with 78% of CISOs responding that today’s AppSec attack surfaces are unmanageable a.....»»
Earth may have had all the elements needed for life—contrary to theories that they came from meteorites
For many years, scientists have predicted that many of the elements that are crucial ingredients for life, like sulfur and nitrogen, first came to Earth when asteroid-type objects carrying them crashed into our planet's surface......»»
