Rising to power in the wake of the Classic Maya collapse, Chich n Itz was among the largest and most influential cities of the ancient Maya, but much about its political connections and ritual life remain poorly understood. Close kin relationships, including two pairs of identical twins, suggests a connection to the Maya origin myths of the Popol Vuh. Further comparison to Maya populations today reveals the genetic impact of... Read more ›

A new study conducted on fruit flies reports the first evidence that oocytes -- the cells that become eggs -- regularly rejuvenate the critical protein linkages that bind chromosomes together. The findings are a potentially important step toward helping women reduce their risk of pregnancy complications as they age. Read more ›

Clouds of gas in a distant galaxy are being pushed faster and faster -- at more than 10,000 miles per second -- out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy's center. It's a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars. Read more ›

By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to date of the growth of the supermassive black holes found in the centers of galaxies. Read more ›

Inspired by the material that makes up oyster and abalone shells, engineers have created a new cement composite that is 17 times more crack-resistant than standard cement and 19 times more able to stretch and deform without breaking. The findings could eventually help increase the crack resistance of a wide range of brittle ceramic materials from concrete to porcelain. Read more ›

Researchers have demonstrated miniature soft hydraulic actuators that can be used to control the deformation and motion of soft robots that are less than a millimeter thick. The researchers have also demonstrated that this technique works with shape memory materials, allowing users to repeatedly lock the soft robots into a desired shape and return to the original shape as needed.

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years... Read more ›

Sepsis -- the leading cause of mortality in children around the world -- can present with a wide range of signs and symptoms, making a one-size-fits-all treatment strategy ineffective. Pursuing a precision medicine approach for pediatric sepsis, researchers used artificial intelligence to analyze a large set of clinical data and find a distinct group of patients who might respond better to targeted treatments.

Haiku poems have reflected humans' experiences in nature for hundreds of years, including observations of bugs and other wildlife. Recently, researchers analyzed which insects were mentioned the most in haiku -- with butterflies, fireflies and singing insects such as crickets topping the list. Read more ›

Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.

Using tools of modern genetics, plant biochemists have produced a new high-yielding oilseed crop variety -- a yellow-seeded variety of Camelina sativa, a close relative of canola, that accumulates 21.4% more oil than ordinary camelina. Read more ›

Researchers have examined viewer responses to images of distressing and neutrally decorated masks and whether personal life history, particularly past experiences of trauma and difficulty, affected how the person perceived the imagery. Read more ›

By using AI to assist with cancer contouring, the researchers found predicting the cancer size was 45 times more accurate and consistent than when physicians used only conventional clinical imaging and blood tests to predict the cancer extent. Read more ›

Researchers have discovered that virus-like nanoparticles can promote the multicellular organization and reproduction of host bacteria. These particles, which are evolutionarily related to phages (viruses that infect bacteria), contain an enzyme that helps shape the multicellular architecture and ultimately enhances morphological differentiation.
