Have you ever wondered why some people turn to violent extremism? Experts have been puzzled by this question for a long time. One tool they use is called Structured Professional Judgement (SPJ), which helps figure out what makes someone more or less likely to engage in extreme behavior. However, the
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
NASA's Artemis program has hit a few bumps on the road to the moon. The plan to land astronauts there by 2026 has been pushed back to at least mid-2027. This isn't the first delay for the program, which has been adjusting its timeline as it prepares for its first crewed mission to the moon since the
China has been on a mission to get more plug-in hybrid electric vehicles (PHEVs) on its roads. The idea is to cut down on carbon dioxide (CO2) emissions by using electricity instead of gas. But does this plan really work? Researchers looked into this from 2016 to 2020. They found that swapping a reg
Earth's atmosphere is heating up, and methane (CH₄) is a big reason why. This potent greenhouse gas is responsible for about one-fifth of the global temperature increase since the preindustrial era, trailing only behind carbon dioxide (CO₂). Over the last five decades, human-caused methane emissions
Imagine big metal boxes, like walk-in refrigerators, in Colombia. These are no ordinary boxes; they're chambers designed to measure something unusual: sheep burps and farts. Why? To understand and reduce methane, a powerful greenhouse gas. Methane is a big deal. It's responsible for a significant c
Blockchain technology is revolutionizing the way we handle transactions and data. It's like a digital ledger spread across many computers, making it secure and transparent. But some blockchains, like Bitcoin, use a lot of energy, which is a big concern for the environment. Bitcoin alone uses about 1
Earth's neighbor, Mars, has long been known to have once hosted extensive water-rock interactions under a carbon dioxide-rich atmosphere. However, carbonate minerals, which are common signs of such interactions, are surprisingly scarce on the Martian surface. Some scientists suggest that these carbo
You might love the scent of a cozy candle burning, but it could be harming your health. Burning candles releases harmful gases called volatile organic compounds (VOCs). The main culprit? Paraffin candles, which are made from petroleum. They can emit toxins like toluene and benzene, which can cause h
Scientists have created a compound called PH2⁻, a type of perylene diimide based radical anion. They tested it using several methods like cyclic voltammetry and differential pulse voltammetry. This compound can last up to 4. 5 hours in low-oxygen conditions. One interesting thing about PH2⁻ is its a
