A systematic review of research on intercultural communication in higher education finds that cultural "power distance," which is the extent to which people accept unequal authority, continues to shape who speaks, who is heard and how knowledge is shared in multicultural
Achieving the blackest of blacks has been one of humanity's enduring challenges. It is a frontier that unites modern nanotechnologists with nature's ancient color palette.
When drinking water is stored in containers, a thin layer of microorganisms can grow at the interface of the container and water. This thin layer is called a biofilm. It's made up of bacteria that make the water unsafe to drink. Slimy biofilms are harder to kill with ordinary

Africa is home to many iconic national parks and marine reserves, such as Virunga in the Democratic Republic of the Congo, Niokolo-Koba in Senegal, Kruger National Park in South Africa and Serengeti National Park in Tanzania. Many of them were established during the colonial
In the dense forests of the Ecuadorian Andes, the survival of a spider relies not only on its ability to prey on insects but also on its capacity to resist a threat coming from the skies. A new study revealed that the heavy rainfall that hits the region acts as an "ecological
Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea stars may offer a unique window into the organ development process.
In a major step toward enhancing food security and exploring the potential to bring rice farming back to Hawaiʻi, an international research team has successfully cultivated premium Japanese rice varieties on Kauaʻi using a water-saving, upland cultivation method. The rice
Groundbreaking modeling has revealed that as many as 220,000 Indigenous Australians died in a devastating 1789 smallpox outbreak that originated in Sydney, tracing its origins to the First Fleet. Soon after British ships arrived, smallpox swept through First Nations communities
We've reported on all kinds of wacky ideas for capturing and deorbiting space debris safely. From electric tethers to lasers, engineers and scientists have been trying everything they can think of to deal with the ever-increasing orbital debris problem. But one simple design
Phase transformations—in which a material changes from one crystal structure to another, thereby acquiring dramatically different properties—are ubiquitous in nature. Understanding the microscopic mechanisms of these transformations is essential for controlling material
Getting as little as 90 minutes less sleep than usual may lead to gaining weight and becoming more sedentary, a new study finds

One day, tiny swimming robots may travel through the human body to deliver drugs. The medication would target only areas of need—chemotherapy drugs for a tumor, for example—avoiding healthy tissue and minimizing side effects. A research team led by Ebru Demir, an assistant
Imagine a student spending hours meticulously erasing and rewriting a paragraph that is already excellent.
The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.
Tuberculosis, caused by the bacterium Mycobacterium tuberculosis (Mtb), is the world's deadliest single-agent infection, responsible for 1.23 million deaths in 2024, according to the World Health Organization. The bacterium's unique outer cell membrane is notoriously hard to
With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more clearly than ever before. That is certainly the case for the new Square Kilometer
The U.S. capital, Washington, saw its worst air quality of the year over the July 4 weekend, as smoke from a massive fireworks display sent pollution soaring to levels considered very unhealthy for the entire public, data showed Monday.
A series of experiments shows that bees respond differently to tastes depending on their internal states, hinting that they have something akin to our emotions
Next-generation batteries that use new electrolyte materials could achieve far higher energy density than today's lithium-ion batteries, without many of the safety concerns. But advanced batteries, such as those that use solid or almost-solid electrolytes, have been plagued by
Every year, thousands of parrots confiscated from the illegal wildlife trade arrive at rehabilitation centers across Latin America. For many of these birds, rescue centers can provide safety but not necessarily a path back to the wild.
A cave on the Turkish Mediterranean coast was inhabited first by Neanderthals and then Homo sapiens, but the continuity of tools and personal objects suggests there was some sharing of culture between the two species
The Canadian astronaut who was part of the historic Artemis II crew that successfully voyaged around the moon earlier this year is retiring from the nation's space agency, officials said Monday.
Over generations, a small North American frog has learned how to survive in a world that's getting increasingly saltier. But new research from the University of Missouri suggests that adaptation comes with an unexpected trade-off.
Heavy rain and flooding are breaking a heat wave that gripped New York City and much of the Northeast last week.
A new University of Mississippi-led study suggests that a telepractice resilience program may help children who stutter develop coping and self-advocacy skills.
Neutron sources can be directly identified from measured spectra rather than proxies using inference tools adapted from cosmology, according to a University of Michigan Engineering study published in Physical Review Applied. The method can improve nuclear security by helping
