In contrast, young adults tend to deactivate certain brain regions. These findings suggest that older adults can adapt to challenging situations, although their brains may respond ...
A study found that early cognitive deficits in premature infants, such as poorer attention and recognition memory, fully account for lower cognitive scores at 2- and 3-years-old. The researchers also discovered a cascade of effects where speed influenced memory, which then impacted general cognitive ability.
Scientists studying the Helheim glacier in Greenland found it has sped up from 70 feet per day to nearly 110 feet per day, thinning by over 130 feet since 2001. This accelerated melting could have dramatic implications for climate models and increase sea level rise.
A focus on process can minimize decision difficulty for high-stakes choices like financial investments and healthcare. By honing in on a succinct decision process, individuals can make decisions more efficiently, especially when faced with aversive options.
The study reveals that consumers' feelings can either promote or deter purchases, depending on whether the product is perceived as mood-lifting or negative. Those in a positive emotional state are more likely to be receptive to products, while those in a negative state are not.
A study of 14,200 patients with type 2 diabetes found that fenofibrate reduced total CVD events by 11% due to a decrease in non-fatal heart attacks and bypass surgery. The drug was well-tolerated but associated with increased risks of pancreatitis and pulmonary embolism.

Researchers followed nearly 6,000 women with metabolic syndrome over nine years, finding that cardiorespiratory fitness reduced overall deaths and heart disease-specific deaths to rates similar to those without the condition. Higher levels of cardiorespiratory fitness were associated with lower risk factors and improved heart health.
A recent study found considerable variation in drink size, particularly for spirits and wine, which can affect individuals' ability to track their alcohol consumption. The study suggests that using a single standard drink size of 0.6 ounces may be helpful for simplifying messages about safe drinking limits.
A recent study found that consumers are more likely to choose a brand with letters similar to their own name. This effect is most pronounced when self-esteem or immediate need for the product are involved. The research suggests that specific conditions, such as threatening situations or relevant needs, influence this phenomenon.
A new multilateral initiative aims to develop a sustainable malaria research infrastructure in Africa by supporting competitively awarded grants for centers of excellence. Trained African scientists are crucial in assembling interdisciplinary teams and conducting research projects focused on developing better tools to fight the disease.
