Scientists are always looking for better ways to control DNA biosensors. These sensors use DNA to detect specific substances, and they can be made even more sensitive by using something called signal amplification. The problem is, controlling this amplification process can be tricky. That's where ex
Do you know that something tiny can make a big difference in cleaning up our environment? Scientists have found a way to use really small particles of bismuth to help turn a harmful chemical into something useful. This chemical, called 4-nitrophenol (4-NP), can be turned into 4-aminophenol (4-AP) us
Imagine extremely tiny threads, so small you'd need a powerful microscope to see them—these are nanofibers. They're exciting in the world of science because they can be adjusted for all sorts of uses. One way to create these fibers is through a process called electrospinning, which gives them a big
A shocking turn of events has left many NYC families worried. Private and homeschooled kids needing special education services were recently denied resources due to a missed form deadline. This news came as a rude awakening to about 3, 000 families who learned that their children would not receive c
Education secretaries often face scrutiny, but the treatment they receive can be very different based on their political affiliation. Take Linda McMahon, Trump's pick for the job. She's been bashed by teachers unions and major news outlets like The Washington Post and The New York Times, labeled a "
Have you ever wondered if there are physical signs that give away a liar? Research shows that detecting deception might trigger specific changes in our bodies. This review took a closer look at eleven studies that examined the kind of physiological responses detectors have when they sense someone is
What happens if you have surgery after catching COVID-19? A new study set out to answer this question. The researchers wanted to know if patients with symptoms at the time of surgery faced more lung problems or even died after their operations. They also compared patients who had recovered from COVI
Have you ever wondered how tiny particles like cells can be moved around in tiny tubes? Scientists often use something called acoustofluidics to do this. It's like using sound to control the dance of these particles. One common tool for this is a microchannel made of a material called polydimethylsi
Oral exams are like a game of chance—they can be fair or unfair, depending on who's asking the questions. In India, a team aimed to fix this by structuring oral exams for first-year med students. They made sure all questions were equal in number, time, and difficulty. Afterward, they asked students
Picture this: you're at your favorite sports bar, watching a game with friends. You decide to make things more interesting by placing a friendly wager. Now, imagine if this could be done easily and safely through an app. That's precisely what Lucra, a startup from Stanford, is offering. They've crea
