Land plants began reshaping Earth 455 million years ago, scientists discover
Pinpointing when early land plants colonized terrestrial environments and began influencing Earth's systems is a core question in the evolution of the Earth sys...
New study highlights significant costs in large-scale mechanical thinning of forests
There is a long history of the mechanical thinning of forests in standard forestry operations. Thinning typically involves removing some 30–50% of the standing...
Humanity's oldest geometries, engraved on ostrich eggs
At several archaeological sites in southern Africa, hundreds of highly unusual fragments of ostrich eggs have been found. Dating back more than 60,000 years, th...
Modern science catches up with native knowledge with discovery of Clerodendrum kelli
The indigenous Bugkalot people of Nueva Ecija call it "kelli": a plant with white, starburst-like flowers and oval-shaped leaves that are traditionally mashed a...
Smarter shelf strategy can boost retail profits and cut food waste by more than 20%, study finds
Grocery retailers may not need new technology—or behavior change from shoppers—to meaningfully reduce food waste. New research in the journal Management Science...
2D memristors could help solve AI's energy problem
New generations of memristors could reliably store information directly within the molecular structures of graphene-like materials. In a new review published in...
How long could Earth microbes live on Mars?
Searching for past or present life on Mars is the sole driving force behind every mission we send to the red planet, from orbiters to landers to rovers. However...
Viruses reveal shared way to kill bacteria by jamming small transporter MurJ
Biochemists at Caltech have identified how viruses have converged on a method for killing bacteria. The researchers have homed in on an underexplored small tran...
The physics of sneaker squeaks: High-speed imaging shows how they arise from supersonic detachment pulses
Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long be...
'Tiny' dinosaur, big impact: A 90-million-year-old fossil rewrites history
A team co-led by University of Minnesota Twin Cities researcher Peter Makovicky and Argentinean colleague Sebastian Apesteguía has identified a 90-million-year-...
Researchers create DNA detection tool to stop spread of invasive Asian swamp eels, bullseye snakeheads
In the canals, marshes, and swamps of the Florida Everglades, invasive fish are silently slipping into new waterways. Among them are the Asian swamp eel and the...
ALMA explores giant molecular clouds in nearby galaxy NGC 1387
An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to investigate molecular gas in a nearby galaxy known...
