The warming climate could put food supplies at risk over the next decade or two.Using various combinations of climate models, David Lobell at Stanford University, California, and Claudia Tebaldi at the National Center for Atmospheric Research in Boulder, Colorado, compared expected yields of maize
Saturn's largest moon, Titan, has a buried ocean that is saltier than many seas on Earth.Titan, with its thick atmosphere and bodies of surface liquid, is of great interest to scientists looking for life beyond Earth. A team led by Giuseppe Mitri, of the
The recent disappearance of a commercial airliner has highlighted our poor knowledge of the ocean floor. Through the years, human tragedies have helped inspire deep sea research, but it is time to explore more systematically.
Expansion of geothermal energy use across the globe is restricted by out-of-date prejudices. It is time for geothermal exploration to be extended to a broader range of environments and rejuvenated with the latest insights from relevant geoscience disciplines.
The processes responsible for the growth of Earth's first continents are enigmatic. The geochemical signature of 4-billion-year-old rocks discovered in Canada points to a key role for shallow magmatic processes above upwelling mantle rocks.
The origins of topographic relief are challenging to disentangle. Modelling shows that differential isostatic rebound due to erosion of rocks of variable density may influence topography, inspiring a fresh look at topographic highs in landscapes.
In the mature brain, the neurotransmitter GABA can cause a postsynaptic hyperpolarization via activation of chloride permeant GABAA receptor channels. This hyperpolarizing response critically depends on chloride extrusion via the KCl-cotransporter KCC2 . Its knockdown in mice impairs synaptic inhibition by changing the electrochemical potential for chlori […]
A20 (also known as TNFAIP3) is a deubiquitinating enzyme (DUB) that ensures optimal immune responses in cells stimulated by cytokines, such as TNF and IL-1, or pathogen components, such as lipopolysaccharide. Deletion of A20 in mice results in multi-organ inflammation and death within 2 weeks . The anti-inflammatory functions of A20 have been attributed t […]
Synthetic endocrine disrupting chemicals (EDCs), omnipresent in food, household, and personal care products, have been implicated in adverse trends in human reproduction, including infertility and increasing demand for assisted reproduction. Here, we study the action of 96 ubiquitous EDCs on human sperm. We show that structurally diverse EDCs activate the sp […]

The orbitofrontal cortex and ventral striatum encode expected outcomes during economic decision-making. Research now demonstrates that activity in these structures also represents missed opportunities during a foraging task cleverly designed to elicit regret in rats, the Restaurant Row task.
A report reveals that giant subcortical heterotopia is caused by mutation of a microtubule-associated protein, Eml1. Defects in Eml1 lead to disruption of the radial migratory scaffolding network in mice and humans.
A leading therapeutic molecule for multiple sclerosis, FTY720, is shown to mimic a key component of sphingolipid signaling, resulting in specific manipulation of histone deacetylases and the extinction of memory.
Plans for a new opencast mine near South Africa’s Hluhluwe-Imfolozi reserve may increase pollution and poaching in the area, which would lead to further reductions in the size of the local southern white rhinoceros population. Among the most charismatic and recognisable of Africa’s mega-fauna, the white rhinoceros is the largest of the five rhinoceros speci […]
The Galápagos archipelago is known for its extraordinarily rich abundance and diversity of native plants and animals found nowhere else in the world. However invasive species present on islands are threatening the Galápagos’ rare species, pushing many to the brink of extinction. To date, seven vertebrate species have become extinct, while 40% of the still ex […]
Over 200 hundred years ago, the United States declared its independence and became its own sovereign nation. Often celebrated in America with BBQs and fireworks, the universal color scheme for any gathering today includes red, white and blue. We thought we’d celebrate the 4th of July here at Arkive… but with our own wildlife twist! […]
Over $1.8 billion has been pledged by various parties at the ‘Our Ocean’ 2014 summit, and proposals have been made to double the amount of protected marine habitats around the world. ‘Our Ocean’ 2014 brought together leaders from business, government and academic institutions, and NGOs from over 80 countries to discuss how economic development and […] […]
