Deep down in the seafloor anaerobic microbes consume large amounts of methane, a potent greenhouse gas when it enters […]

A typical endurance horse (Arabian breed) presented for a gait test before the start of the race to check locomotor soundness. During an endurance competition (100-160 km), horses must undergo veterinary inspection at the end of each 20 to 40 km loop to check their recovery and capacity to continue […]

Māori wrasse are large, colorful fish that can be found on the Great Barrier Reef. In a ground-breaking new study, scientists used innovative molecular techniques to explain how corals on the east coast of Australia survived previous tough conditions—enabling the Great Barrier Reef to become the vast reef it is […]

A unique stress experiment aligned deoxygenation stress to the natural night-day cycle of common reef-building corals from The Great Barrier Reef. Credit: Morgan Bennett-Smith Ocean deoxygenation is now being recognized as major threat to future global coral reef survival. Oxygen is life, in or out of the water, raising concerns […]

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.
