Dopamine, serotonin involved in sub-second perception, cognition. In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals — dopamine and serotonin — are at work at sub-second speeds to shape how people perceive the world and take action based on their perception. The […]

Rubisco is the most abundant enzyme on the planet. Present in plants, cyanobacteria (also known as blue-green algae) and other photosynthetic organisms, it’s central to the process of carbon fixation and is one of Earth’s oldest carbon-fixing enzymes. Researchers at UC Davis and LBNL have now discovered an alternative form […]

Patrice Cani (UCLouvain) and Claude Knauf (INSERM) have discovered a ‘jammer’ that blocks communication between the gut and the brain, thus preventing proper regulation of sugar and causing insulin resistance in people with diabetes. They also discovered that a lipid produced by our body helps prevent this dysfunction and regulate […]

International scientists and Ngātiwai, a Māori tribe, teamed up to sequence the genome of a rare reptile, the tuatara, uncovering some unique aspects of the tuatara’s evolution. The genome sequence will enable comparative studies to better understand the evolution of the tuatara and its distant relatives: other reptiles, birds, and […]

Oxytocin, the hormone that induce feelings of love and well-being within us, are found to reverse some of the damage caused by amyloid plaques in the learning and memory center of the brain in an animal model of Alzheimer’s.

These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of […]

Researchers from the RIKEN Center for Advanced Photonics and collaborators have discovered that terahertz radiation, contradicting conventional belief, can disrupt proteins in living cells without killing the cells. This finding implies that terahertz radiation, which was long considered impractical to use, may have applications in manipulating cell functions for the […]
