Soybean seeding rates and risk

A recent study by Corteva Agriscience and universities across the US has determined the optimal seeding rate for soybean growers, providing help to reduce risk and optimize yield potential. The research found that farmers should increase seeding rates in areas of lower productivity and reduce them in areas of higher productivity.

Why visual perception is a decision process

Researchers found that prediction errors can be accessed during final processing stages of perception, contradicting previous theories. This means the brain simultaneously keeps track of past, current, and future image contents, allowing for stability and flexibility in rapid image sequences.

Hey, Alexa, who else is listening right now?

Researchers at the University of Cincinnati are exploring potential security weaknesses in voice-activated speakers like Alexa and Google Home. They found that hackers can exploit devices using a passive attack called 'voice command fingerprinting', which involves eavesdropping on data transferred between the smart speaker and the clou...

Tiny sensors fit 30,000 to a penny, transmit data from living tissue

The team's microsensors can measure inputs like voltage and temperature in hard-to-reach environments, such as inside living tissue. They successfully embedded a sensor in brain tissue and wirelessly relayed the results, paving the way for generations of microsensors that use less power while tracking more complicated phenomena.

The downside of feeling prepared

Researchers found that feelings of preparedness in one area can lead to more confident thoughts about unrelated topics, even if those thoughts are not based on actual knowledge. Participants who were told they had to prepare for bad news later showed more positive attitudes towards research funding proposals than those who didn't prepare.

North pole will be ice-free in summer

A new study suggests that reducing CO2 emissions rapidly could lead to ice-free years in the Arctic, occurring only occasionally. The research indicates that humans can still determine how often the Arctic Ocean will be ice-free, depending on future emissions levels.

Charismatic invasive species have an easier time settling into new habitats

Research found that the physical characteristics of charismatic invasive species, such as body size and coloration, contribute to their appeal and can lead to increased human interaction and difficulty in management. Conversely, other species that are considered problematic may be viewed less favorably due to cultural perceptions.
