A pair of anthropologists at Tulane University has solved the mystery of the Mayan 819-day count, a type of ancient Mesoamerican calendar system. In their paper published in the journal Ancient Mesoamerica, John Linden and Victoria Bricker suggest that the calendar might be representing a much longer timescale than others had considered.

Plant nutrient content reflects their overall metabolic health and has a direct impact on plant growth, development, and reproduction. Nonstructural carbohydrates (NSCs), for example, are a type of temporary storage for carbohydrates that accumulate in trees and are thought to be indicative of plant carbon availability and supply.

Abstract The climate feedback determines how Earth’s climate responds to anthropogenic forcing. It is thought to have been more negative in recent decades due to a sea surface temperature “pattern effect,” whereby warming is concentrated in the western tropical Pacific, where nonlocal radiative feedbacks are very negative. This phenomenon has however primarily been studied within climate models.

It is one of the most exciting races in modern physics: How can we produce the best superconductors that remain superconducting even at the highest possible temperatures and ambient pressure? In recent years, a new era of superconductivity has begun with the discovery of nickelates. These superconductors are based on nickel, which is why many scientists speak of the "nickel age of superconductivit

In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs (miRNAs), which are now known to be present across all forms of life. As it turns out, these molecules play essential roles in many biological processes.

Ribonucleic acids (RNAs) are single-stranded molecules that play an essential role in the cells of all living organisms.

Torrents of charged particles continuously lift off the sun’s atmosphere and radiate outward at millions of kilometers per hour, yielding a solar wind so immense that its limit defines the outer edge of our solar system.

The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea surface. Clumps of dead algae also transport the plastic with its pollutants particularly quickly into the deep sea — and can thus explain the high mi
