The Pauli exclusion principle is a cornerstone of the Standard Model of particle physics and is essential for the structure and stability of matter. Now an international collaboration of physicists has carried out one of the most stringent experimental tests to date of this
Proteins are the molecular machines of cells. They are produced in protein factories called ribosomes based on their blueprint—the genetic information. Here, the basic building blocks of proteins, amino acids, are assembled into long protein chains. Like the building blocks of
Imagine an asteroid striking Earth and wiping out most of the human population. Even if some lucky people survived the impact, Homo sapiens might still face extinction, because the social networks humans rely on would collapse.
Authorities have evacuated more than 140,000 people from their homes since heavy rainfall flooded several provinces in northern Morocco last week, the interior ministry said Thursday.
Conventional wisdom is that waiting in a queue online or in a physical line involves a certain cost for people and organizations. Rational analysis has largely based its queue management predictions on remaining wait time, or how long someone has left to wait. Much of the
Muscles make up nearly 40% of the human body and power every move we make, from a child's first steps to recovery after injury. For some, however, muscle development goes awry, leading to weakness, delayed motor milestones or lifelong disabilities. New research from the
A deadly storm that triggered floods and thousands of evacuations in the Iberian Peninsula sparked calls on Thursday for Portugal's presidential run-off to be postponed, but electoral officials insisted it would go ahead.
Right now, molecules in the air are moving around you in chaotic and unpredictable ways. To make sense of such systems, physicists use a law known as the Boltzmann distribution, which, rather than describe exactly where each particle is, describes the chance of finding the
The magnitude 6.9 earthquake that took place in 2018 on the south flank of Kīlauea on the Island of Hawaiʻi may have stalled episodes of periodic slow slip along a major fault underlying the volcano, according to a new study by scientists at the U.S. Geological Survey.
It's not what they intended to do or expected to find. They're not even all that interested in birds. When Andre Naranjo and his colleagues began work on a new study published in the Botanical Journal of the Linnean Society, they wanted to know why a small mountain chain on the

Whatever challenges life throws, mothers often know best as they guide offspring through the risky stages of early development. This scenario, familiar when applied to humans, turns out to be true for plants too, according to intriguing research from the John Innes Center and
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are called geomagnetic reversals, and the record of these flips is preserved in rocks
Despite decades of independent progress in population ecology and movement ecology, researchers have lacked a theoretical bridge between these two disciplines. "Ecologists have been trying to establish this link since the 1950s, when they started to characterize animal movement
Researchers at Wageningen University & Research have developed a new type of plastic that, according to materials theory, should not be able to exist. Its properties sit somewhere between those of glass and plastic: it is easy to (re)shape, yet resistant to impact. This unusual

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in our planet's mantle, the layer sandwiched between the thin crust and Earth's molten core. The new map will help scientists learn more about the
At the 15th UN Biodiversity Conference (COP15) in Montreal, Canada, in 2022, nations committed to reducing the risks associated with pesticide use in agriculture by 50% by 2030. A new study by a research team from RPTUKaiserslautern-Landau, published in the journal Science,
Babies are born with the ability to predict rhythm, according to a study published February 5 in the open-access journal PLOS Biology by Roberta Bianco from the Italian Institute of Technology, and colleagues.
A combination of weakened atmospheric removal and increased emissions from warming wetlands, rivers, lakes, and agricultural land increased atmospheric methane at an unprecedented rate in the early 2020s, an international team of researchers report today in the journal Science.
In a series of tea party-like experiments, Johns Hopkins University researchers demonstrate for the first time that apes can use their imagination and play pretend, an ability thought to be uniquely human.
Brain scans and signals show babies can sort images and sense rhythm, offering new insight into how infant brains are wired from the start.
Apes, like humans, are capable of pretend play, challenging long-held views about how animals think, a new study suggests.
In biology, many RNA molecules act as sophisticated microscopic machines. Among them, riboswitches function as tiny biological sensors, changing their 3D shape upon binding to a specific metabolite. This shape-change acts as a switch, often turning a downstream gene "on" or
Parents often tell their children to sound out the words as they are learning to read. It makes sense: Since they already know how to speak, the sound of a word might serve as a clue to its meaning.
The South Carolina measles outbreak has triggered rare but serious brain swelling in some children
