Why nanoscale droplets don't coalesce and microscale droplets do
Water and oil droplets behave differently based on size due to their molecular properties. Nanoscale droplets remain separated while microscale droplets merge, a distinction relevant to emulsion stability in applications like salad dressings that use emulsifiers such as mustard or mayonnaise.
This tiny organism contracts 200 times faster than we can blink—here's how
Spirostomum ambiguum, a single-celled organism, contracts to one-quarter of its body length in less than 5 milliseconds using a calcium-activated protein network in a fishnet-like configuration. This contraction speed far exceeds human muscle capabilities and may inform development of faster artificial muscles and synthetic cellular machinery.
Camera traps reveal the true culprit behind crop damage in Honduras
Camera traps deployed in Honduran Mosquitia identified which wildlife species was causing crop damage in the region. The research was published in Neotropical Biology and Conservation journal using noninvasive monitoring technology.
Compliant farmers could face fewer inspections under new water pollution proposals
Farmers meeting water quality standards could receive fewer regulatory inspections under proposed changes to the Nutrients Action Policy. The policy revision aims to adjust enforcement frequency based on compliance records rather than universal inspection schedules.
Giant exoplanet may hold a magnetic grip on its host star
A giant exoplanet may exert magnetic forces on its host star, reversing the assumed one-directional relationship between stars and their orbiting planets. Researchers observed this potential interaction in a system where the star's magnetic field appears influenced by the planet's presence.
Mummified dogs reveal Tiwanaku people buried companions beside homes long before they became status symbols
Tiwanaku people in southern Peru buried mummified dogs near their homes around 1,100 years ago, with remains showing careful placement on woven mats. Only two intentionally buried mummified dogs from this culture have been discovered, with one young dog possibly wrapped in twine.
Toward experiment-guided AlphaFold: Researchers overcome AI tool's single-conformation limitation
AlphaFold can now be guided with experimental data to predict multiple protein conformations instead of collapsing heterogeneous structures into a single dominant shape. Researchers at ISTA developed this approach by incorporating experimental conditions that alter local protein structure, as published in Nature Biotechnology.
The order of species loss alters how grasslands maintain stability, study finds
The sequence in which plant species disappear from grasslands affects how well these ecosystems maintain their stability and function. Grasslands comprising 40% of terrestrial ecosystems play crucial roles in supporting livestock food sources, pollinator habitats, and carbon storage.
These tiny soil microbes could rescue crops from salty farmland
Soil bacteria stimulate lignin production in plant roots, making crops more resilient in salty soils. Greenhouse and field tests demonstrated healthier plants and higher yields when these beneficial microbes were present in salt-affected conditions.
The oldest evidence of mourning rituals reveals Paleolithic communities grieved like we do
A 15-year-old boy mauled by a bear roughly 27,500 years ago in Liguria, Italy, was attended by others during his final moments, as evidenced by archaeological findings at Arene Candide. The skeletal remains show injuries to his jaw, neck, and left shoulder, with evidence suggesting his community performed mourning rituals similar to modern grief practices.
Lost megalodon vertebrae resurface, confirming 80-foot size estimate
A set of megalodon vertebrae missing since the 1980s was rediscovered, confirming the extinct shark reached 80 feet in length. Researchers from Danish and international institutions analyzed the specimen to learn about the megatooth shark's lifestyle and behavior patterns.
Human activity has driven retreat of Antarctica's fastest melting glacier
Human-driven climate change intensified the retreat of Pine Island Glacier during the 20th century. The glacier drains a large part of the West Antarctic Ice Sheet into the Amundsen Sea and is one of the biggest contributors to global sea level rise.
Europe swelters as heat wave moves east
A heat wave moved eastward across Europe on Sunday, affecting hundreds of millions of people despite some overnight storm relief in France and Belgium. The extreme temperatures continued spreading despite temporary weather breaks from the storms.
Three firefighters die battling huge wildfires on Colorado-Utah border
Three firefighters died while battling wildfires burning along the Colorado-Utah border. Multiple blazes sparked emergency declarations from governors in both states.
