After a 3.5-year voyage at sea, scientists have discovered more than 100,000 new eukaryotic organisms, many existing in symbiotic relationships with each other.Scientists aboard the research schooner Tara collected some 35,000 ocean samples at 210 locations around the world, from as deep as
Dormant stem cells — and the signals that activate them — are widespread across surfaces in adult mouse brains.Yi Eve Sun and Siguang Li of Tongji University School of Medicine in Shanghai, China, and their colleagues analysed patterns of gene expression in individual cells
Subduction zone faults can slip slowly, generating tremor. The varying correlation between tidal stresses and tremor occurring deep in the Cascadia subduction zone suggests that the fault is inherently weak, and gets weaker as it slips.
Mountain glaciers around the world are in decay. According to a modelling study that — unusually — includes full ice flow physics, those in Western Canada will largely be restricted to the coastal region by the year 2100.
Titan's equatorial dunes seem to move in the opposite direction to the prevailing easterly winds. Infrequent methane storms at Titan's low latitudes may briefly couple surface winds to fast westerlies above, dominating the net movement of sand.
Almost a third of the world's people do not have access to hygienic latrines. Improving access to and increasing the use of latrines would reduce deaths and poor health caused by diarrheal – [Read More]
The unfolded protein response (UPR) is a major signaling cascade that determines cell fate under conditions of endoplasmic reticulum (ER) stress. The kinetics and amplitude of UPR responses are tightly controlled by several feedback loops and the expression of positive and negative regulators. In this issue of EMBO Reports, the Wilkinson lab uncovers a novel […]
The control of cell fate decisions is vital to build functional organs and maintain normal tissue homeostasis, and many pathways and processes cooperate to direct cells to an appropriate final identity. Because of its continuously renewing state and its carefully organised hierarchy, the mammalian intestine has become a powerful model to dissect these pathwa […]
Animal rights extremists are threatening nonhuman primate research by harassing scientists. We cannot tolerate these tactics, and we must rally individual, institutional and governmental support to protect scientists.
The prefrontal cortex is known to influence dopamine release in the striatum–but how? New data in mice suggest that cortical spine density affects striatal dopamine release via monosynaptic control of dopamine neurons, tracing a chain of events from spine loss to antipsychotic-responsive psychomotor agitation.
Observing the choices of others adds utility to the chosen option. The additional utility conferred by others' choices is encoded by the ventromedial prefrontal cortex and explains the idiosyncratic effects of social influence.
Happy World Turtle Day Everyone!! The first ever World Turtle Day started in 2000 and was sponsored by the American Tortoise Rescue. This day aims to bring attention to and increase knowledge and respect for turtles and tortoises. It encourages humans to take action to help them survive and thrive in the wild. Here at Arkive, […]
