A never-before-seen biodiversity pattern of coral reef fishes suggests some fishes might be exceptionally vulnerable to environmental change. It highlights, for the first time, a unique link between the diet and distribution of species across the marine realm. Source: Fish diet heats up marine biodiversity hotspot

Wearable sleep tracking devices – from Fitbit to Apple Watch to never-heard-of brands stashed away in the electronics clearance bin – have infiltrated the market at a rapid pace in recent years. And like any consumer products, not all sleep trackers are created equal, according to neuroscientists. Source: You snooze, you lose – with some […]

The brain’s neural activity is irregular, changing from one moment to the next. To date, this apparent ‘noise’ has been thought to be due to random natural variations or measurement error. However, researchers have shown that this neural variability may provide a unique window into brain function. Source: How the 'noise' in our brain influences […]

Researchers have developed a new tool for addressing disseminated intravascular coagulation (DIC) – a blood disorder that proves fatal in many patients. The technology has not yet entered clinical trials, but in vivo studies using rat models and in vitro models using blood from DIC patients highlight the tech’s potential. Source: New tech aims to […]

Researchers reveal transformation of colon organoids in vitro. Escherichia coli bacteria are constitutive members of the human gut microbiota. However, some strains produce a genotoxin called colibactin, which is implicated in the development of colorectal cancer. Source: Genotoxic E. coli 'caught in the act'

Scientists used accelerometers to track daily activity levels for a week in 89 adults with obesity or overweight and, in a series of tests, measured their ability to multitask and maintain their attention despite distractions. The study revealed that individuals who spent more sedentary time in bouts lasting 20 minutes or more were less able […]
