Monitoring wastewater for traces of infectious diseases is giving this human byproduct a powerful new role in public health. Once used decades ago to detect poliovirus, wastewater-based epidemiology reemerged during COVID-19 and is now proving useful again in tracking measles outbreaks before cases are officially reported.A recent study led by researchers from Baylor College of Medicine, UTHealth Houston, the Houston Health Department, and Rice University showed that measles virus was detected i ...read more

Archaeopteryx lived about 150 million years ago during the Jurassic Period. Although the first Archaeopteryx fossil was discovered more than 160 years ago and the prehistoric bird has been well studied, an excellent specimen has yielded new information about the species, including why it could fly so well, according to a report in the journal Nature. Painstaking preparation made the “Chicago Archaeopteryx” (named because it resides in the city’s Field Museum) the best-preserved example of ...read more

Earth has been home to life for billions of years, but could the planet itself be considered a living thing? Most people simply think of Earth as a giant rock — one with the perfect conditions to nurture life as we know it today, from animals and plants to microscopic bacteria. But English environmental scientist James Lovelock thought differently. Departing from traditional scholarly views, Lovelock collaborated with American evolutionary biologist Lynn Margulis in the 1970s to develop a new ...read more

Using advanced medical algorithms, researchers have identified six breast texture patterns that may indicate a high risk for breast cancer. In a new study, one of the largest of its kind, published in the journal Radiology, a research team analyzed the mammograms of over 30,000 women and condensed the information down into six phenotypes. With this new information, the research team hopes to improve breast cancer screening and prevention. Breast Tissue PatternsFull-field digital mammography ( ...read more

In 2022, archeologists unearthed what appeared to be the oldest intact reed boat. It was found buried in a sediment-filled former channel of the Euphrates River, near the ancient city of Uruk, in the Mesopotamian floodplain of what is now Iraq.“The findings provide valuable insights into the utilization of Uruk's waterways, the evolution of its floodplain, and the broader processes that shaped early urbanization in Mesopotamia,” according to the conference paper.Analyzing the Ancient BoatAlt ...read more

Underneath miles-deep ice sheets covering Antarctica lies the largest mountain range no one on Earth has ever seen. Even though a few of its tallest points peek through in some places, relatively few people know of the entire range’s existence.However, geologists studying it have long argued about how and when these buried peaks were formed. A team of geologists propose a new explanation in an article in the journal Earth and Planetary Science Letters.“The ice conceals some of Earth’s most ...read more

The exotic pet trade brings millions of animals into the U.S. every year. One of these animals, the tegu, is a popular reptile import thanks to its flashy looks and docile personality. Once it grows to its full 5-foot, 10-pound size, however, it often ends up escaping or being set free into the wild. In Florida, it is considered an invasive species and is of special interest to wildlife biologists and conservationists since it’s a menace to local ecosystems. Recently, the tegu has become of s ...read more

Humans display different ways of attaching to one another, shaped largely by how our caregivers responded to us in early childhood. Some of us may shy away from closeness and prefer emotional distance, while others feel anxious in relationships, seeking reassurance and fearing abandonment. Understanding these underlying attachment styles can help us navigate emotions and relationships — and, as it turns out, might even help us better understand ourselves through the eyes of our primate relativ ...read more

During an excavation, amidst the Patagonian winds and hard rock, a fossil began to turn green. It was an unexpected reaction: the adhesive applied to protect the bones, fragile after millions of years beneath the ice, had interacted with plant matter trapped in the rock’s cracks. This greenish hue earned the fossil the nickname Fiona, like the ogre from Shrek.But Fionais much more than a ogre-themed name. It is the first complete ichthyosaur ever excavated in Chile and, even more remarkably, t ...read more

There are animals out there that glow, and a lot more of them than you might think. Indeed, you may assume that it’s only the gleaming fish, squid, and shrimp that make their own light. But many mammals glow, too, not through bioluminescence, but through photoluminescence, a distinct biological process that’s best spotted by observing animals under ultraviolet, violet, or blue light.A team of researchers recently set out to identify the chemistry that makes some mammals glow under these wave ...read more
