NUS marine scientists find toxic bacteria on microplastics retrieved from tropical waters

A recent study by NUS researchers found that microplastics can harbor toxic bacteria capable of causing coral bleaching and triggering wound infections in humans. The study identified over 400 types of bacteria on the plastics, including species that can degrade pollutants and others that cause harm to marine organisms.

Learning a second alphabet for a first language

A new study has shown that adults can learn a fictional writing system called HouseFont, which assigns images of houses to English phonemes. The research found increased brain activity in the visual word form area that predicted participants' reading speed, suggesting that learning a new writing system shapes the reading brain.

Medical bills financially burden almost half of cardiovascular disease patients

A study published in the Journal of the American College of Cardiology found that 45.1% of adult atherosclerotic cardiovascular disease (ASCVD) patients experience financial hardship due to medical bills. Insured and uninsured individuals, particularly those with lower incomes, are disproportionately affected.

Zwicky Transient Facility spots a bumper crop of supernovae, black holes and more

The Zwicky Transient Facility (ZTF) has discovered over 1,100 supernovae, two black holes, and 50 near-Earth asteroids since its operations began in March 2018. The facility is also conducting a systematic study of transients in galaxy nuclei, aiming to catch stars being ripped apart by supermassive black holes.

Famous 'sandpile model' shown to move like a traveling sand dune

Moritz Lang and Mikhail Shkonikov from IST Austria have discovered a new property of the Abelian sandpile model, showing that it can exhibit dynamics similar to those of real-world sand dunes. The researchers used a specific method to add sand grains to the model, which induced self-similar fractal patterns reminiscent of the Mandelbro...
