Orcas are known to be smart and ruthless hunters. They've been observed hunting a variety of prey, with some species, such as whales, larger than themselves. They use a wide range of strategies to hunt and kill prey, but now, in the Gulf of California, researchers have observed
This strategy expands orcas’ already broad repertoire for dispatching different types of prey.
A new study of incarcerated women in Chile reveals that women respond to imprisonment in very different ways: While most experienced little change in their involvement in crime after release, those with higher levels of past criminal involvement transitioned toward less

A major new study led by Swansea University has shown that upstream river management, rather than local rainfall, is the primary driver of one of the world's most important wetlands. According to the research published in Scientific Reports, which analyzed more than two decades
The first five years (2019–2024) of operations of The Ocean Cleanup's Automated Debris Imaging System (ADIS) have been reviewed, and the findings have been published in Environmental Research Communications. In addition to reviewing the technology's performance, the study
All cellular life—from humans to bacteria—possesses two layers of immunity: innate and adaptive. Scientists have long understood how these two types of immunity work together in higher organisms but not in the microbial world.
The seafloor plays an important ecological and societal role. Understanding the processes that shape this environment will help guide conservation policy and decision-making about underwater infrastructure and geohazards.
The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how disease-causing bacteria control the production of proteins needed to cause infection. E. coli TGT is nearly identical to the one found in Shigella, which causes
Many people drive more carefully for a while after receiving a traffic fine. But do large corporations, such as airlines, also change their behavior when they face financial penalties? We examine this question by studying penalties imposed in the United States for lengthy
Researchers at the University of Twente have developed an optical method that follows the shape changes of a single protein in liquid without attaching anything to it. It reads the protein's structure from its own molecular vibrations, free from the labels or tags that other
A research team led by UCLA and the University of Rochester has demonstrated a promising evolution of an imaging system designed to capture details within "complex media," which scatter light, from depicting structures inside body tissue to seeing obstacles through heavy fog.
Semiconductor surfaces can generally be studied only with considerable experimental effort, for example, in an ultrahigh vacuum. To more easily gain new insights into their properties and the possibilities for targeted modification, scientists at Heidelberg University have
