Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.

A new study by a team of international researchers has uncovered a biological explanation for long-term memories. It centers on the discovery of the role of a molecule, KIBRA, that serves as a 'glue' to other molecules, thereby solidifying memory formation. Read more ›

Made famous in 1995 by NASA's Hubble Space Telescope, the Pillars of Creation in the heart of the Eagle Nebula have captured imaginations worldwide with their arresting, ethereal beauty. Now, NASA has released a new 3D visualization of these towering celestial structures using data from NASA's Hubble and James Webb space telescopes. This is the most comprehensive and detailed multiwavelength movie yet of these star-birthing clouds. Read more ›

Scientists predict from geochemical data that Iceland is entering a new volcanic era that will last for decades, possibly centuries. Under an hour's drive from the country's capital city, the ongoing eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.

Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth's atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth's warming trend and into an anomalous near-glacial period called the Younger Dryas.

Researchers have found a chemical clue in Italian limestone that explains a mass extinction of marine life in the Early Jurassic period, 183 million years ago. Volcanic activity pumped out CO2, warming oceans and lowering their oxygen levels. The findings may foretell the impact climate change and oxygen depletion might have on today's oceans. Read more ›

Early analysis of the asteroid Bennu sample returned by NASA's OSIRIS-REx mission has revealed dust rich in carbon, nitrogen, and organic compounds, all of which are essential components for life as we know it. Dominated by clay minerals, particularly serpentine, the sample mirrors the type of rock found at mid-ocean ridges on Earth. The magnesium-sodium phosphate found in the sample hints that the asteroid could have splintered off from an... Read more ›

New research describes how nerve cells and muscle cells communicate through electrical signals during development -- a phenomenon known as bioelectricity. The communication, which takes place via specialized channels between cells, is vital for proper development and behavior. The study identifies specific genes that control the process, and pins down what happens when it goes wrong. The finding offers clues to the genetic origins of muscle disorders in humans. Read more ›

The nine-banded armadillo, which ranges all the way from Argentina to Nebraska, is actually four separate species. One of the species, the Guianan long-nosed armadillo, is new to science. Meanwhile, the species that has migrated from Mexico to the United States (and is the official small mammal of Texas) is now called the Mexican long-nosed armadillo. Read more ›

A national position statement on emergency action plan development and implementation in sports from an athletic training researcher sets in motion new priorities for responding to catastrophic injuries. The recommendations apply to sports through all levels, from youth to high school to collegiate and professional leagues. Read more ›

Even though there is substantial variability in the contents and nutritional profiles of plant-based meat alternatives (PBMAs), the nutritional profiles tend to reflect a heart-healthy dietary pattern. A review article of the available studies directly comparing the impact of plant-based and animal-based meats consistently suggests that the plant-based alternatives improve cardiovascular risk factors.

In October 2013 a researcher made a surprising discovery of Painted Lady Butterflies on the Atlantic beaches of French Guiana -- a species not typically found in South America. This unusual sighting prompted an international study to investigate the origin of these butterflies. Read more ›

There's a strong chance that last week's scorching temperatures were even hotter than reported for those living in underserved urban areas. New research from environmental engineers has shown that citizen science tools used to gauge heat in these urban areas likely understate the problem of heat islands due to a lack of weather stations. The researchers also suggest a statistical method to improve estimates of urban heat. Read more ›

Alfred Hitchcock observed that 'There is no terror in the bang, only in the anticipation of it.' A common way to build suspense in a movie scene is for the audience to know something bad is going to happen, but not when it is going to happen. But how does uncertainty work to ratchet up our anxiety? Researchers took a deeper look into what builds fear. Read more ›
