United States of North America: a Comic for the Jade Helmers of Canada

I live in Texas and hear a lot of conspiracy theories. The one about a North American Union is popular. Radio demagogues such as Alex Jones and the recent Jade Helm military exercises keep it alive and the public afraid.The entire continent of North America?—?so the tale goes?—?will soon be one giant country.

Four-legged fossil holds secret of snake’s slithering origins

An ancient animal with a serpent-like body plan and four tiny legs could reveal details about the evolutionary origins of snakes

Watch boa constrictor cut off rat’s blood supply in record time

Boa constrictors were thought to suffocate their prey, but a new experiment suggests that they target the circulatory system instead

Cyborg cockroach and drone teams can locate disaster survivors

Roaches with electronic implants and managed by drones can be tasked to locate trapped people in the aftermath of an earthquake

Is Wayward Pines Genetically Plausible?

Tonight is the final episode, ever, of Wayward Pines, the 10-episode FOX television show that’s the best sci-fi I’ve seen since the X-Files. The series, based on a trilogy by Blake Crouch, has a seemingly simple set-up. Random people, except … Continue reading » The post Is Wayward Pines Genetically Plausible? appeared first on DNA Science Blog.

Semen has controlling power over female genes and behaviour

Seminal fluid alters gene expression in females, including humans. It can even alter behaviour in fruit flies, but does it do the same in women?

Updating the Winged Dragon – Zhenyuanlong

How do we Know that Zhenyuanlong was Quite Big? A few days ago, on July 16th, Everything Dinosaur team members published an article that featured the newly described Chinese dromaeosaurid dinosaur known as Zhenyuanlong suni.  We explained why the dinosaur called Velociraptor was used to help give this new dinosaur discovery context and outlined some of the more […]

The cost of Mediterranean Sea warming and acidification: a choice experiment among scuba divers at Medes Islands, Spain

A choice experiment is undertaken to elicit preferences of scuba divers in the Marine Protected Area of Medes Islands (Spain). This is the first non-market valuation study of a typical Mediterranean habitat, the Coralligenous, which is characterized by high biodiversity, geomorphologic complexity and iconic species like gorgonians.

Seagrass beds as ocean acidification refuges for mussels? High resolution measurements of pCO2 and O2 in a Zostera marina and Mytilus edulis mosaic habitat

It has been speculated that macrophytes beds might act as a refuge for calcifiers from ocean acidification. In the shallow nearshores of the western Kiel Bay (Baltic Sea), mussel and seagrass beds are interlacing, forming a mosaic habitat. Naturally, the diverse physiological activities of seagrasses and mussels are affected by seawater carbonate chemistry and they […]

SOCAN webinar: “Modeling ocean circulation and biogeochemical variability in the Southeast U.S. coastal ocean and Gulf of Mexico”, 28 July 2015

Presented by Ruoying He, North Carolina State University Date & time: Tuesday, 28 July 2015, 12:00pm ET Abstract Changing climate and rising atmospheric CO2 coupled with impacts of human activity, have the potential to dramatically alter...Show More Summary

Gains and losses of coral skeletal porosity changes with ocean acidification acclimation

Ocean acidification is predicted to impact ecosystems reliant on calcifying organisms, potentially reducing the socioeconomic benefits these habitats provide. Here we investigate the acclimation potential of stony corals living along a pH gradient caused by a Mediterranean CO2 vent that serves as a natural long-term experimental setting. Show More Summary

Ocean acidification may cause dramatic changes to phytoplankton

Study finds many species may die out and others may migrate significantly as ocean acidification intensifies. Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans […]

Impact of ocean acidification on the structure of future phytoplankton communities

Phytoplankton form the foundation of the marine food web and regulate key biogeochemical processes. These organisms face multiple environmental changes1, including the decline in ocean pH (ocean acidification) caused by rising atmospheric pCO2 (ref. Show More Summary

Ocean acidification increases fatty acids levels of larval fish

Rising levels of anthropogenic carbon dioxide in the atmosphere are acidifying the oceans and producing diverse and important effects on marine ecosystems, including the production of fatty acids (FAs) by primary producers and their transfer through food webs. Show More Summary

Predicting effects of ocean acidification and warming on algae lacking carbon concentrating mechanisms

Seaweeds that lack carbon-concentrating mechanisms are potentially inorganic carbon-limited under current air equilibrium conditions. To estimate effects of increased atmospheric carbon dioxide concentration and ocean acidification on...Show More Summary

Ocean acidification has different effects on the production of DMS and DMSP measured in cultures of Emiliania huxleyi and a mesocosm study: a comparison of laboratory monocultures and community interactions

The human-induced rise in atmospheric carbon dioxide since the industrial revolution has led to increasing oceanic carbon uptake and changes in seawater carbonate chemistry, resulting in lowering of surface water pH. In this study we...Show More Summary
