Reindeer sleep while chewing their cud

Researchers found that reindeer spend more time ruminating and less time in non-REM sleep, suggesting a possible restorative function of rumination. The study suggests that reindeer may be able to save time by resting during rumination, allowing them to cope with limited sleep time during the arctic summer.

Vervet monkeys follow different social “norms” and respond to “peer pressure,” new long-term study shows

A new long-term study has found that vervet monkeys in neighboring groups have distinct social traditions, with some exhibiting more affiliative behaviors than others. The researchers observed that males adapted their social style to match their new group, suggesting a phenomenon akin to social conformity driven by peer pressure.

Grinding coffee with a splash of water reduces static electricity and makes more consistent and intense espresso

Researchers found that adding water to coffee beans before grinding reduces static electricity, resulting in less wasted coffee and cleaner grinders. Grinding with water also produces more consistent and intense espresso. The study's findings have significant economic implications for the $343.2 billion coffee industry.

Mice pass the mirror test, a classic indicator of self-recognition

Researchers found that mice require significant external sensory cues to recognize changes in their reflection and can detect visual differences, but not tactile ones. The study identified a subset of neurons involved in developing self-image, highlighting the neural mechanisms behind self-recognition in mice.

How to build greener data centers? Scientists say crank up the heat

Scientists propose new temperature guidelines for data centers that may help reduce energy consumption and save money. Researchers found that raising the temperature to around 41°C could lead to significant savings, with some areas able to rely entirely on free-cooling, reducing energy costs by up to 56%.

Researchers measure global consensus over the ethical use of AI

A systematic review of global guidelines for AI use found that most valued principles such as transparency, security, and justice. However, fewer guidelines prioritized truthfulness, intellectual property, and children's rights. Most guidelines were normative but lacked practical methods for implementation.

Warm summers and wet winters yield better wine vintages

Researchers analyzed 50 years of Bordeaux wine critic scores with weather data to show that warmer temperatures, higher rainfall, and earlier seasons yield better vintages. Climate change is predicted to increase these conditions, potentially improving wine quality, but water scarcity poses a risk.

Carbon-capture tree plantations threaten tropical biodiversity for little gain, ecologists say

Ecologists say that carbon-capture tree plantations have a negative impact on tropical biodiversity and ecosystem services, despite their potential to offset climate change. In contrast, intact ecosystems like forests, grasslands, and savannahs store large quantities of carbon below ground and provide multiple ecosystem services.

Ocean acidification makes ecologically important seaweed species fragile

A study found that ocean acidification reduced the strength and density of fleshy seaweed tissues, making them more fragile and susceptible to damage. The research suggests that this could have drastic effects on coastal ecosystems, leading to a decrease in seaweed coverage and negatively impacting organisms dependent on these habitats.

Jellyfish shown to learn from past experience for the first time

Scientists demonstrated that Caribbean box jellyfish can acquire the ability to avoid obstacles through associative learning, a process in which organisms form mental connections between sensory stimulations and behaviors. The study suggests that combining visual and mechanical stimuli is required for associative learning in jellyfish.
