When learning a second language (L2), many are likely familiar with the challenge of memorizing vocabulary, only to struggle with recalling and using it fluently in speech. Studies have found that speaking fluently in L2 depends not only on knowing what words mean but also on how quickly and automatically you can access and use them appropriately in contexts. This ability to retrieve contextually appropriate word meanings without conscious effort is known as automatized vocabulary knowledge (AVK). In a new study, a team of researchers led by Mr. Kotaro Takizawa from Waseda University, Japan, along with Prof. Kazuya Saito and Dr. ...

Researchers have discovered a simple yet powerful way to protect atoms from losing information—a key challenge in developing reliable quantum technologies. By shining a single, carefully tuned laser beam on a gas of atoms, they managed to keep the atoms' internal spins synchronized, dramatically reducing the rate at which information is lost. In quantum sensors and memory systems, atoms often lose their magnetic orientation—or "spin"—when they collide with each other or the walls of their ...

When we’re taking antibiotics, some of the dose is excreted with urine and feces and ends up in our wastewater. The presence of this low dose of antibiotic creates an opportunity for resistant bacteria to evolve. Scientists studying antibiotic resistant bacteria in wastewater at a treatment plant discovered multi-drug resistant strains of bacteria species which are usually not dangerous to healthy people, but which could transmit genes for antibiotic resistance to much more dangerous bacteria like E. coli.   The scientists then challenged the bacteria with natural compounds which could potentially be included in wastewater treatment to kill off bacteria and fight ...

More than a thousand fish species use sounds to exchange information, attract mates, and avoid predators through hums, grunts, clicks, and bubbles. Yet, the vital role of fish sounds—and the impact of noise pollution on the fishes that produce them—are left out of critical conservation policy, says study led by marine ecologists at Simon Fraser University. The ocean is filled with the bustling sounds of daily marine life, including the sounds made by soniferous fish species. These sounds aren’t merely passive sounds—soniferous fishes produce sound themselves, like a whale ‘singing’ through vocalizations, says Kieran ...

Fungi are increasingly resistant to antifungals, and the variation in resistance has significantly increased. This is evident from the analysis of more than 12,000 lung samples collected over thirty years in Dutch hospitals. In addition, a resistant infection in a patient almost always consists of different fungal strains, making treatment more challenging. This study by Radboud university medical center and public health institute RIVM has been published in The Lancet Microbe. When consultant microbiologist Paul Verweij and his team began collecting Aspergillus fumigatus isolates from patients’ lungs in 1994, they did not ...
