Understanding the northward movement of the subtropical westerly jet in changing climates

The subtropical westerly jet has been shifting northward under global warming, with research suggesting that temperature changes are the primary driver. According to a new study, about 72% of the jet's northward movement is due to changes in temperature, while eddy-driven effects account for around 28%.

Proteogenomic signatures may help identify risk of prostate cancer progression in patients with African and European ancestries

A study found that proteogenomic signatures in prostate cancer tissue from patients with African and European ancestries were associated with a higher risk of metastasis and/or recurrence. The study identified mutation signatures and recurrent copy number alterations that correlated with disease progression.

What’s quieter than a fish? A school of them

Researchers found that synchronization of tail flaps in a school of fish reduces sound, with the single biggest key being alternating flaps rather than unison movement. This phenomenon could have significant implications for prey fish, allowing predators to perceive them as individual fish rather than a group.

System uses artificial intelligence to detect wild animals on roads and avoid accidents

A team of researchers developed an AI-powered computer vision model to detect Brazilian wild animals on roads and warn drivers in real-time. The system uses roadside cameras and portable computers to identify species such as anteaters, wolves, and tapirs, with the potential to save lives and reduce roadkill.

Can the bias in algorithms help us see our own?

A new study by Carey Morewedge and colleagues found that people are more likely to recognize bias in algorithmic decisions than their own. This is because algorithms can codify and amplify human bias, but also reveal structural biases in society. The research suggests ways to increase awareness of biases and correct them.
