Discovery of ‘Punk’ and ‘Emo’ fossils challenges our understanding of ancient molluscs
Researchers have unearthed two fossils, named Punk and Emo, revealing that ancient molluscs were more complex and adaptable than previously known. Molluscs are one of life’s most diverse animal groups and analysis of the rare 430 million year old fossils is challenging long-held views on their early origins. The fossils dating from the Silurian period…

Dopamine and Serotonin Drive Emotional Word Processing
Summary: Researchers have uncovered how neurotransmitters in the brain respond to the emotional content of language, shedding light on the intersection of emotion, cognition, and communication. Using advanced techniques, the team simultaneously measured dopamine, serotonin, and norepinephrine release in patients during exposure to emotionally charged words. They found distinct patterns of… Continue Reading News Source:…

New Study Shows ‘Anomalous Rocks’ Deep Inside Earth
A new computer model shows blobs of cooler rocks (in blue) in Earth’s mantle where none should be. Sebastian Noe/ETH Zurich A team of geophysicists created a detailed model of Earth’s lower mantle using earthquake waves. This indicates the presence of zones of rocks that are colder, or have a different composition, than our current…

Warming threatens flies more than bees, raising pollination concerns
New research shows flies can tolerate temperatures 2.3°C lower than bees before losing motor function, making them particularly vulnerable to climate change and raising concerns about their crucial role as the world’s second most important pollinators. The study, conducted across three countries, reveals that flies’ sensitivity to heat is especially… Continue Reading News Source:…

Electrical Synapses Enhance Sensory Decision-Making
New Haven, Conn. — Scientists at Yale and the University of Connecticut have taken a major step in understanding how animal brains make decisions, revealing a crucial role for electrical synapses in “filtering” sensory information. The new research, published in the journal Cell , demonstrates how a specific configuration of electrical synapses enables animals to…

Most of the atoms in your body left the Milky Way on a ‘cosmic conveyor belt’ long before you were born, new study reveals
Most of the atoms in your body likely spent millions of years circling the Milky Way on a cosmic “conveyor belt” before returning to our galaxy prior to the solar system‘s creation, a new study suggests. Most elements in the universe, except for hydrogen and helium (and a few other weird exceptions), were forged by…
