Sharks off Brazil’s coast have tested positive for cocaine, a first-time detection in free-ranging sharks. Scientists from the Oswaldo Cruz Foundation found cocaine in liver and muscle tissue of all 13 Brazilian sharpnose sharks. The species was chosen due to its small size and exposure to contaminants. Cocaine levels were three times higher in muscle … Read more
A study found that dogs can smell human stress and make decisions based on it. The research involved 18 dogs and their owners, who were asked to give a speech and do math tasks while being recorded for stress levels. The dogs were then given food bowls with different scents and were trained to recognize … Read more
A study has revealed a more efficient method for creating methanol. For years, chemists have been striving to synthesize valuable materials from waste molecules. Now, an international team of scientists is investigating how electricity can simplify this process. In their study, recently published in Nature Catalysis, researchers demonstrated that carbon dioxide, a greenhouse gas, can … Read more

Everyone needs their comfort show. Killing Time What do you do after a long day of exploring and collecting data on a cold, alien desert world? Thanks to NASA’s simulated Mars habitat experiment, we might have an answer. According to microbiologist Anca Selariu, who lived in a 3D-printed mock-up of a Mars base for 378 … Read more
Young people today are experiencing unprecedented levels of stress, depression, and unhappiness, a trend that is shifting the traditional pattern of happiness. According to David Blanchflower, a professor of economics, research shows that young adults (ages 18-25) report being unhappier than people in their 40s and 50s. The traditional U-shaped happiness curve, which suggests that … Read more
A new antibiotic that works in two ways could make it extremely difficult for bacteria to develop resistance. Researchers from the University of Illinois Chicago found that a class of synthetic drugs called macrolones can disrupt bacterial cell function by either interfering with protein production or corrupting DNA structure. Macrolones are created by combining the … Read more
The Roots of Ambivalence What hinders us from making a positive change? Ambivalence is normal when it comes to behavior change. Recognizing its two root causes is key to resolving it. 1. Lack of understanding about the true cause of ambivalence can lead to self-judgments that keep us stuck. 2. Low importance and low confidence … Read more
A research team from HKUST has improved perovskite solar cell performance by eliminating surface concavities on individual crystal grains, making this promising technology more commercially viable. The researchers discovered that these concavities significantly impact the film’s properties and reliability. To address this issue, they developed a new method to remove these grain surface concavities using … Read more
