Biodegradable bubble moves away from lactic acid without a motor—a step toward artificial cells‎

A tiny biodegradable bubble can move away from a chemical on its own, without a motor. Living cells need complex molecular machinery to do this. This discovery by researchers led by chemist Daniela Wilson at Radboud University, together with colleagues at Durham University, is a step toward artificial cells with lifelike behavior and could, in the long term, provide an interesting approach for self-steering particles in targeted drug delivery.

Scientists challenge the dream of bringing extinct species back to life‎

Could extinction itself become a thing of the past? Advances in biotechnology, including ancient DNA sequencing, genome analysis and gene editing, have led some to believe that it may be possible to bring extinct species back to life.

Chip identifies cells by their electrical signature, then separates them with a precisely aimed sound wave‎

In biomedicine, sorting cells accurately without damaging them remains a persistent problem. Current methods, like fluorescence-activated cell sorting, rely on labeling the cells extrinsically, which can stress the cells, alter their behavior and even interfere with the assay. A collaborative study between researchers in Singapore and China has now developed a noninvasive, label-free method to sort cells.

From remedy to prevention: Researchers call for proactive approach to protect the human right to water‎

More than 2 billion people, or approximately one-quarter of the world's population, lack access to safe water, sanitation and hygiene, according to the United Nations Children's Fund. Today, 16 years after the U.N. General Assembly recognized this access as a fundamental human right, its legal protection is well established, but the reality on the ground lags behind.

Symbolic clay figurines change our understanding of the prehistoric Middle East‎

Newly discovered artifacts are evidence of the earliest known example of a tradition of making clay figurines in the Middle East—and challenge long-held beliefs about when and how clay began to be used for symbolic purposes in the region, according to a study published in PLOS One by Laurent Davin from The Hebrew University of Jerusalem, Israel, and colleagues.

Monkey foot and palm prints differ between individuals, as they do in humans‎

In three species of monkey, the complex pattern of ridges on the feet and palms varies between individuals, similar to human fingerprints, according to a study published in the open-access journal PLOS One by Juliana Vieira Flores Sales at Universidade de Brasília and colleagues.

Misunderstandings about statistics common even among experienced researchers‎

Even researchers and people with extensive training in statistics often find it difficult to interpret statistical results correctly. This is shown by a new systematic review carried out by Uppsala University and others, in which researchers have analyzed 55 studies involving over 15,000 participants. The work is published in PLOS One.

Spain's massive stone tombs reveal collective burials continued well into Bronze Age‎

Iberian people continued using, and possibly building, massive necropolises well into the Bronze Age, according to a study published in PLOS One by Eduardo Vijande-Vila of the University of Cádiz, Spain, and colleagues.

Frozen sperm enables embryo development in endangered Japanese bird for first time—but chick fails to hatch‎

The Okinawa rail (Hypotaenidia okinawae) is an endangered flightless bird endemic to the Yanbaru forest region of Okinawa Island in Japan. The bird has only recently begun recovering its numbers after introduced predators, such as the mongoose, and traffic accidents reduced its population to as low as 820 individuals.

Overheating cattle: More and more dangerous heat is coming for northern Australia's herds‎

The Sunday roast and the backyard barbecue have long been Australian rituals. The country is one of the world's biggest consumers of red meat. The average Australian ate about 22 kilograms (49 pounds) of beef in 2024.
