A machine-learning approach developed for sparse data reliably predicts fault slip in laboratory earthquakes and could be key to predicting fault slip and potentially earthquakes in the field.
Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis. This research provides new insight that connects the characteristics of earthquakes -- magnitude, depth where two tectonic plates slip past each other and the rigidity of the plates involved -- with the potential...
As our brains age, small lesions begin to pop up in the bundles of white matter that carry messages between our neurons. The lesions can damage this white matter and lead to cognitive deficits. Now, researchers not only provide an explanation for the location of these lesions but also how they develop in the first place.
Federal wildlife officials say two species of rare insects in the Rocky Mountains will need several thousand acres of glaciers and snowfields if they are to survive a warming world that's threatening them with extinction.
Sounds from a Ganymede flyby, magnetic fields, and remarkable comparisons between Jupiter and Earth's oceans and atmospheres were discussed during a briefing today on NASA's Juno mission to Jupiter at the American Geophysical Union Fall Meeting in New Orleans.

The first genome-wide ancient human DNA data from Sudan reveals new insights into the ancestry and social organization of people who lived more than 1,000 years ago in the Nile Valley, an important genetic and cultural crossroads.

Forest restoration treatments can reduce future fire severity and benefit populations of California spotted owls, even with temporary disruptions within owl habitats in the Sierra Nevada, CA.
A machine-learning approach developed for sparse data reliably predicts fault slip in laboratory earthquakes and could be key to predicting fault slip and potentially earthquakes in the field. The research by a Los Alamos National Laboratory team builds on their previous success using data-driven approaches that worked for slow-slip events in earth but came up short on large-scale stick-slip...
The world's most consumed fruit and an important staple for many developing companies, bananas are increasingly threated by Blood disease, so named because cut banana stems look like they are bleeding. Blood disease causes fruit rot, leaf wilt, and plant death. There is no known cure for the disease.
The use of fungicides to treat plant pathogens dates back 150 years, when a mixture of lime and copper sulfate, known as the "Bordeaux mixture," was used to control fungal diseases in French vineyards. However, as fungicide usage has increased, their efficacy has decreased thanks to a phenomenon known as fungicide resistance.
Scientists report that norepinephrine, a fundamental chemical for brain performance, is locally regulated in a brain region called the visual cortex.
Forest restoration treatments can reduce future fire severity and benefit populations of California spotted owls, even with temporary disruptions within owl habitats in the Sierra Nevada, CA.
Just days after a volcano erupted on the Spanish island of La Palma, Roselio Gonzalez's home—and a lifetime of memories—was engulfed by lava and ash.

At least 12 people have died in the strongest typhoon to hit the Philippines this year, the disaster agency said Friday, after the storm swept across the archipelago uprooting trees, toppling power poles and flooding villages.
Students will be able to apply to Harvard University without submitting SAT or ACT scores for at least the next four years, the Ivy League school announced Thursday, extending a policy many colleges have adopted during the pandemic and that a growing number are keeping for years to come.
The mugshot-style photos are posted on online message boards in black and white and look a little like old-fashioned "wanted" posters.
My aunt Margaret Waddy, who has died aged 77 of a pulmonary embolism, was a horticulturist and a teacher, a quiz fan and a committed volunteer with Samaritans in Cambridge.Margaret was born in London but her early life was spent in the Gold Coast, now Ghana, where her parents, Bernard (known as BB) Waddy, a doctor in tropical medicine, and Mary (nee Lawrence), worked for the Colonial Service. At...
Improved understanding is a necessary first step in the process of managing the loss of an archaeological site, and the Seaford Head Project is trialing ways of achieving this including 3D modeling and surveying the site with drones. The project will also trial the use of podcasts and videos to engage local communities in a conversation about coastal change and how they feel about the eventual,...
Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory have developed an effective computational method to simulate the crazy-quilt movement of free electrons during experimental efforts to harness on Earth the fusion power that drives the sun and stars. The method cracks a complex equation that can enable improved control of the random and fast-moving moving...
NASA is shooting for next Friday to launch its newest space telescope.
