UC Davis researchers look at how the brain prioritizes what we see

UC Davis researchers analyze electrical brain activity to understand how the brain prepares to focus attention on specific features, such as color or direction of movement. The study found that the brain's attention first broadens to a general category before narrowing down to the specific feature, taking an average of 240 milliseconds...

Inconsistent charging stations hinder EV adoption

A survey by University of Washington researchers found that participants with a negative view of public charging were less likely to choose an electric vehicle than those with a moderate view. Participants demanded strikingly large concessions, such as a 30% discount or 366 extra miles of range, before choosing an EV.

Chinese scientists identify neural basis for energy expenditure in arcuate hypothalamus

Researchers have identified a new population of hypothalamic neurons, Crabp1 neurons, that play a critical role in regulating energy expenditure. Silencing these neurons leads to reduced energy expenditure and obesity, while activating them enhances locomotor activity and protects against high-fat diet-induced weight gain.

Fewer traffic deaths with a speed limit of 75

A recent study analyzing data from 2017 to 2019 found that introducing a 75 mph speed limit reduces injury crashes by about 9% and fatal crashes by 35, with significant reductions in severe injuries. The results suggest speed limits are particularly effective at entry and exit points and less frequented roadways.
