Niagara fireball event leads to discovery of tiniest known asteroid
In an international study led by Western University and Lowell Observatory, scientists describe a pioneering, integrative approach for studying near-Earth asteroids based largely on a November 2022 fireball event that dropped meteorites in the Niagar.....»»
Ryugu asteroid sample rapidly colonized by terrestrial life despite strict contamination control
Panspermia is the hypothesis that life can survive the transfer between planetary bodies as a secondary path for life to get started on planets throughout a solar system. The discovery of extraterrestrial life on asteroids or within meteorites would.....»»
Scientists construct first complete energy spectrum of solar high-energy protons in Martian space
Scientists have constructed the first complete proton energy spectrum observed during an eruptive solar event in Martian space, deepening our understanding of the radiation environment around Mars......»»
2 million mph galaxy smash-up seen in unprecedented detail
A massive collision of galaxies sparked by one traveling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes......»»
Siri chatbot may be coming in 2026 as part of iOS 19
A new rumor suggests Apple wants to make Siri more conversational by making it use a large language model backend similar to ChatGPT and AI rivals, but it won't be ready until 2026.Siri could get an LLM backend in 2026When Apple was first rumored to.....»»
We’re closer to re-creating the sounds of Parasaurolophus
Preliminary model suggests the dinosaur bellowed like a large trumpet or saxophone, or perhaps a clarinet. The duck-billed dinosaur Parasaurolophus is distinctive for its prominen.....»»
Introducing "UFO" galaxies—the Milky Way"s dustier cousins
In a new study, a team of astrophysicists led by CU Boulder has set out to unravel the mysteries of UFOs—not the alien spacecraft, but a class of unusually large and red galaxies that researchers have nicknamed Ultra-red Flattened Objects, or UFOs.....»»
Astronomers take first close-up picture of a star outside our galaxy
Located a staggering 160,000 light-years from us, the star WOH G64 was imaged thanks to the impressive sharpness offered by the European Southern Observatory's Very Large Telescope Interferometer (ESO's VLTI). The new observations reveal a star puffi.....»»
Madagascar"s huge ocean algae bloom was caused by dust from drought-stricken southern Africa
Scientists have found new evidence that desertification, potentially linked to global warming, leads to large amounts of nutrient-rich dust landing in the sea, causing ocean algae to grow rapidly. Biological oceanographer John A. Gittings and an inte.....»»
Researchers develop pioneering monitoring technique to help build mangrove resilience
Mangroves are remarkable ecosystems home to amazing biodiversity, dense vegetation, and conditions that capture large quantities of carbon. Since they occur in warm, tropical, and subtropical coastal regions, they also take the brunt of the impact fr.....»»
It"s been 100 years since we learned the Milky Way is not the only galaxy
On Sunday November 23, 1924, 100 years ago this month, readers perusing page six of the New York Times would have found an intriguing article, amid several large adverts for fur coats. The headline read: Finds Spiral Nebulae are Stellar Systems: "Dr......»»
New language encodes shape and structure to help machine learning models predict nanopore properties
A large number of 2D materials like graphene can have nanopores—small holes formed by missing atoms through which foreign substances can pass. The properties of these nanopores dictate many of the materials' properties, enabling the latter to sense.....»»
Quantum DXi9200 helps organizations manage and reduce cybersecurity risks
Quantum announces the DXi9200, the latest generation of its flagship DXi9000 Series hybrid (flash + dense disk) data protection appliances, designed for scalable, efficient backup and recovery services for large organizations. With the continuing thr.....»»
Astronauts found to process some tasks slower in space, but no signs of permanent cognitive decline
A stay in space exerts extreme pressures on the human body. Astronauts' bodies and brains are impacted by radiation, altered gravity, challenging working conditions, and sleep loss—all of which could compromise cognitive functioning. At the same ti.....»»
A year after ditching waitlist, Starlink says it is “sold out” in parts of US
SpaceX's Starlink doesn't have enough capacity for everyone who wants it. The Starlink waitlist is back in certain parts of the US, including several large cities on the West Coas.....»»
Niantic uses Pokémon Go player data to build AI navigation system
Visual scans of the world have helped Niantic build what it calls a "Large Geospatial Model." Last week, Niantic announced plans to create an AI model for navigating the physical.....»»
Electromagnetic Symphony: Explore the EMF Universe
Make EMF radiation audible and listen in to the silent backbone of our electronics society with an EMF audio amplifier. The post Electromagnetic Symphony: Explore the EMF Universe appeared first on Make: DIY Projects and Ideas for Makers......»»
Why school police officers may not be the most effective way to prevent violence
In 1975, only 1% of public schools had their own police officers. Today, 44% do. A large reason for the increase is the Violent Crime Control and Law Enforcement Act of 1994, which led to the creation of the federal Community Oriented Policing Servic.....»»
Statistical approach improves models of atmosphere on early Earth and exoplanets
As energy from the sun reaches Earth, some solar radiation is absorbed by the atmosphere, leading to chemical reactions like the formation of ozone and the breakup of gas molecules. A new approach for modeling these reactions, developed by a team led.....»»
The new Mars landing approach: How we"ll land large payloads on the Red Planet
Back in 2007, I talked with Rob Manning, engineer extraordinaire at the Jet Propulsion Laboratory, and he told me something shocking. Even though he had successfully led the entry, descent, and landing (EDL) teams for three Mars rover missions, he sa.....»»
