Manganese is an essential trace element. However, in excessive concentrations, the metal can cause health problems. Two Eawag researchers have now produced a global risk map for manganese in groundwater. Half of the world's population uses groundwater as drinking water.
Across North America, in places such as Illinois, Iowa and Texas, farmers are busy growing the crops the world depends on for food, fuel and fiber.
Maize (corn) is a major dietary staple in Maya communities past and present because of its reliability, potential for surplus, and suitability as both food and fodder. It became so important to ancient Mesoamerican communities that it even became central to many of their
Feeling hot at home may seem like a simple matter of temperature or whether the air conditioning is switched on. But a new study suggests that less visible factors—from closed windows and blocked airflow to household routines and the different ways family members experience
A modelling study suggests marine cloud brightening could shade the eastern Pacific and reduce a global temperature spike from El Niño, but there could be unexpected consequences
The chemical substance behind these visions isn’t like any other known to science The post Hunting for a New Hallucinogen in the Lilliputian Psychedelic appeared first on Nautilus .
Astronomers spend much of their time mapping the universe, but until now their results have been collected and archived in so many different ways that the data can't talk to each other.
RNA has emerged as one of the most promising molecules in modern medicine, enabling advances from mRNA vaccines and gene therapies to genome editing and synthetic biology. However, designing RNA molecules that reliably fold into a desired secondary structure remains a major
New Michigan State University-led research suggests the difference between a hiring policy that harms recruiting and one that doesn't may come down to just a few words.
Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun's tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions of high-energy particles and radiation from the sun
Psychedelic drugs are known to make people highly sensitive to their surroundings. In other words, a user's mindset and immediate environment heavily shape the entire trippy experience. In a study published in the journal Psychedelic Medicine, scientists wanted to test a
When engineers think about protective materials, like those used in packaging and support, they usually think about strength, stiffness and durability. But what if those same materials could also sense their external environment?
A new study reveals that exposing dwarf spiders to a brief period of warm temperatures can disrupt a phenomenon in which internal bacteria normally force genetic males to develop as females. Surprisingly, this reproductive disruption skips the directly heated spiders and hits
Raindrops form inside clouds when tiny particles of water collide and stick together, forming larger droplets that eventually fall to Earth. This process is hard to model accurately, with current approaches either imprecise or computationally intensive. Better simulations of
The science behind nature’s different puncture tools The post The Surprising Evolutionary Trade-offs Between Fangs, Stingers, and Claws appeared first on Nautilus .
Two new studies examining gray wolves in California paint a complex picture of life on the state's ranching landscapes: Wolves eat cattle more than anything else, and the presence of the predators causes significant stress among livestock.
