Saturday Citations: Volcano vs. asteroid; NASA"s supernova time lapse; immortal chemicals
This week, we're highlighting a study involving toxic chemical contaminants, and just for fun, a second study involving other toxic chemical contaminants. But NASA made a cool time-lapse video using the good old Hubble space telescope, and a group of.....»»
An Epic Fight Over What Really Killed the Dinosaurs
A deep learning model has joined a vigorous debate over whether volcanoes began dinosaur doomsday well before the asteroid hit......»»
Study removes human bias from debate over dinosaurs" demise
To help resolve the scientific debate over whether it was a giant asteroid or volcanic eruptions that wiped out the dinosaurs and most other species 66 million years ago, Dartmouth researchers tried a new approach—they removed scientists from the d.....»»
Tropical climates are the most biodiverse on Earth, but it"s not only because of how warm and wet they are
Life exists in every conceivable environment on Earth, from the peaks of towering mountains to the remote stretches of isolated islands, from sunlit surfaces to the darkest depths of the oceans. Yet, this intricate tapestry of existence isn't spread.....»»
Lethal weapon: New antimicrobial coating could revolutionize cleaning methods
We've gained a new weapon in the fight against harmful and often antibiotic-resistant pathogens with the development of a unique material engineered to limit disease spread and replace current cumbersome cleaning protocols on high-touch surfaces like.....»»
Fossils show widespread plant extinctions after asteroid wiped out dinosaurs
Sixty-six million years ago, an asteroid the size of San Francisco crashed into a shallow sea off the coast of modern-day Mexico and plunged the world into an extinction event that killed off as much as 75% of life, including the dinosaurs......»»
Likely asteroid debris found upon opening of returned NASA probe
After a seven-year wait, NASA scientists on Tuesday finally pried open a space probe carrying the largest asteroid samples ever brought back to Earth, finding black debris......»»
Scientists just opened the lid to NASA’s asteroid sample canister
"There is some black dust-like material that's visible. We're hoping that's from Bennu." Enlarge / The lid is open on the OSIRIS-REx sample return canister, revealing a tantalizing ring of dust outside the main sample collection.....»»
NASA"s OSIRIS-REx capsule arrives in Houston
The first U.S. asteroid sample, delivered by the OSIRIS-REx spacecraft to Earth on Sept. 24, has arrived at its permanent home at NASA's Johnson Space Center in Houston, where it will be cared for, stored, and distributed to scientists worldwide......»»
Computer simulation explains mysterious rock patterns seen from Czech Republic to Mars
In geology, honeycombs are an intriguing pattern of small cavities on rock surfaces found in coastal regions, wet areas, deserts, and even on Mars. They are fascinating to look at in natural objects and a bane of historic buildings and monuments. Des.....»»
How NASA Is Protecting Its Precious Asteroid Bennu Sample
The OSIRIS-REx capsule containing a "treasure trove" of space rocks has now arrived at Johnson Space Center, where scientists will gingerly unpack it......»»
Fossils in Morocco reveal the astounding diversity of marine life 66 million years ago, just before the asteroid hit
Sixty-six million years ago, the Cretaceous period ended. Dinosaurs disappeared, along with around 90% of all species on Earth. The patterns and causes of this extinction have been debated since paleontology began. Was it a slow, inevitable decline,.....»»
Q&A: The first asteroid sample returned to Earth
On Sunday morning, a capsule the size of a mini-fridge dropped from the skies over western Utah, carrying a first-of-its-kind package: about 250 grams of dirt and dust plucked from the surface of an asteroid. As a candy-striped parachute billowed ope.....»»
Beyond Bennu: How OSIRIS-REx is helping scientists study the sonic signature of meteoroids
In the high desert of Nevada, Elizabeth Silber watched NASA's Sample Return Capsule from OSIRIS-REx descend into Earth's atmosphere on Sunday, but unlike most scientists, she wasn't there for the asteroid rocks......»»
Major asteroid sample brought to Earth in NASA first
A seven-year space voyage came to its climactic end Sunday when a NASA capsule landed in the desert in the US state of Utah, carrying to Earth the largest asteroid samples ever collected......»»
