Iron snow ebb and flow may cause magnetic fields to come and go
Just as snow crystals form in the upper atmosphere, then fall to lower, warmer elevations and melt, scientists believe a phenomenon called iron snow happens in the molten iron cores of some planetary bodies. Cooling near the core-mantle boundary crea.....»»
New study explores adoption of robotic weeding to fight superweeds
Most corn and soybean fields in the U.S. are planted with herbicide-resistant crop varieties. However, the evolution of superweeds that have developed resistance to common herbicides is jeopardizing current weed management strategies. Agricultural ro.....»»
AI training method can drastically shorten time for calculations in quantum mechanics
The close relationship between AI and highly complicated scientific computing can be seen in the fact that both the 2024 Nobel Prizes in Physics and Chemistry were awarded to scientists for devising AI for their respective fields of study. KAIST rese.....»»
Mars may have been habitable much more recently than thought
Evidence suggests Mars could very well have been teeming with life billions of years ago. Now cold, dry, and stripped of what was once a potentially protective magnetic field, the red planet is a kind of forensic scene for scientists investigating wh.....»»
Innovative model offers new way for astronomers to analyze powerful space explosions
Astrophysical explosions are, to give a few examples, driven by the collapse of the iron core of a massive star (known as a core-collapse supernova), the consumption of spaghettified stellar remains by a massive black hole (known as a tidal disruptio.....»»
Team observes how iron atoms alter grain boundary structures in titanium
Using state-of-the-art microscopy and simulation techniques, an international research team has systematically observed how iron atoms alter the structure of grain boundaries in titanium. Their findings were published in the journal Science on Octobe.....»»
Scientists demonstrate precise control over artificial microswimmers using electric fields
In a new study in Physical Review Letters, scientists have demonstrated a method to control artificial microswimmers using electric fields and fluid flow. These microscopic droplets could pave the way for targeted drug delivery and microrobotics......»»
Investigating the flow of fluids with non-monotonic, "S-shaped" rheology
Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. Under different stresses a.....»»
Discovery of critical iron-transport protein in malaria parasites could lead to faster-acting medications
Malaria kills over 600,000 people a year, and as the climate warms, the potential range of the disease is growing. While some drugs can effectively prevent and treat malaria, resistance to those drugs is also on the rise......»»

What is La Niña? Expert explains how the weather pattern may impact your winter plans
The La Niña event forecast for this winter may deliver more snow than usual to the Northwestern U.S. and dry, warm weather to the South......»»
Microbes feed on iron: New study reveals how they do it
Pipelines, sprinklers, and other infrastructure in oxygen-free environments are vulnerable to microbially induced corrosion (MIC)—a process where microorganisms degrade iron-based structures, potentially leading to costly damages or even collapses......»»
Blasts from the past: New insights from old space storms
On 4 August 1972, a burst of solar plasma rocked Earth's magnetic field after hurtling through space for about 14.6 hours—the fastest sun-to-Earth plasma journey ever recorded. The resulting space storm, one of several that occurred from 2 to 11 Au.....»»
River flow responses to heat waves may change more rapidly under climate change, research finds
A pair of studies by researchers in Simon Fraser University's School of Environmental Science examine how climate change could alter the way Canadian rivers respond to extreme heat events......»»
Internet fiber optic cables successfully detect shock waves from a rockslide
On the night of 16 June 2023, about 1.2 million cubic meters of rock rumbled down into the valley near Brienz (GR). A team from the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and ETH Zurich tracked the event using an unusual.....»»
Experimental study offers insights into mysterious flow features on airless worlds
A Southwest Research Institute researcher collaborated with a team at NASA's Jet Propulsion Laboratory to attempt to explain the presence of mysterious flow features that exist on the surfaces of airless celestial bodies, such as the asteroids Vesta.....»»
Photonic computing method uses electromagnetic waves to rapidly solve partial differential equations
In the fields of physics, mathematics, and engineering, partial differential equations (PDEs) are essential for modeling various phenomena, from heat diffusion to particle motion and wave propagation. While some PDEs can be solved analytically, many.....»»
Scientists untangle the challenging complexities of radiocarbon in ice cores
ANSTO scientists, Dr. Andrew Smith, Dr. Quan Hua and Dr. Bin Yang have contributed to a paper that elucidates how in situ cosmogenic radiocarbon (14C) is produced, retained and lost in the top layer of compacting snow (the "firn layer") and the shall.....»»
New strategy unlocks magnetic switching with hydrogen bonding at molecular level
A research team from Kumamoto University has successfully developed a new approach to create switchable magnetic materials by using hydrogen bonding at the molecular level. Their study shows how certain metal complexes, previously unresponsive to ext.....»»
