Book Review: Tales of Prehistoric Life by Daniel Loxton

This spring, Daniel Loxton published his third and final children's book in the Tales of Prehistoric Life series: Plesiosaur Peril, the story of the dangerous life of a young Cryptoclidus in the Jurassic. It was proceeded by Ankylosaur Attack (2011) and Pterosaur Trouble (2013). Show More Summary

Evidence of Episodic Crustal Formation From the Hadean to the NeoArchean From China

Hadean to Neoarchean episodic crustal growth: Detrital zircon records in Paleoproterozoic quartzites from the southern North China CratonAuthors:Zhang et alAbstract:The Archean terranes exposed in several regions of the North China Craton (NCC) provide important winodws to evaluate the Hadean-Archean continental crustal evolutoin history.

Earth Observing Satellites Note Large Methane Leaks From American SouthWest/Four Corners Regions

An unexpectedly high amount of the climate-changing gas methane, the main component of natural gas, is escaping from the Four Corners region in the U.S. Southwest, according to a new study by the University of Michigan and NASA.The researchers mapped satellite data to uncover the nation's largest methane signal seen from space.

Plasticity predicts evolution in a marine alga

Under global change, populations have four possible responses: ‘migrate, acclimate, adapt or die’ (Gienapp et al. 2008 Climate change and evolution: disentangling environmental and genetic response. Mol. Ecol. 17, 167–178. (doi:10.1111/j.1365-294X.2007.03413.x)). Show More Summary

Fish unable to rapidly adapt to ocean acidification

In high-CO2 water, offspring don’t do much better than their parents. Apart from strengthening the greenhouse effect, our emissions of carbon dioxide also affect the chemistry of the oceans. When CO2 dissolves in water, it lowers the pH, which makes it more difficult for organisms to make calcium carbonate shells. Show More Summary

Nuclear Submarine HMS Astute Completes First Deployment

HMS Astute (S-94) — the first in class of the U.K. Royal Navy’s nuclear attack boats (SSNs) — has returned to Scotland after its first operational deployment, the Royal Navy announced on Thursday.Astute departed its homeport, HM Naval...Show More Summary

Great Barrier Reef: ‘a massive chemistry experiment gone wrong’

Scientists warn that pollution may be dramatically increasing the rate of ocean acidification in inshore areas, threatening coral. It has long been known that pollution is having a devastating impact on the Great Barrier Reef but now scientists are warning that it may also be dramatically increasing the rate of ocean acidification in inshore areas […]

Dissolution dominating calcification process in polar pteropods close to the point of aragonite undersaturation

Thecosome pteropods are abundant upper-ocean zooplankton that build aragonite shells. Ocean acidification results in the lowering of aragonite saturation levels in the surface layers, and several incubation studies have shown that rates of calcification in these organisms decrease as a result.

Les océans de plus en plus acides sous l’effet des émissions de CO2 (in French)

Les coraux en blanchissent de peur: l’acidité des océans a augmenté en moyenne de 26% au cours des 200 ans dernières années, indique un rapport publié ce mercredi. Les océans absorbent plus d’un quart des émissions de CO2 émises par les activités humaines et l’augmentation de ces rejets de dioxyde de carbone met la vie marine […]

Meeting: “Acidification and hypoxia: separate accounts or two sides to a coin?”, AAAS 2015 Annual Meeting, San Jose, CA

Sunday, 15 February 2015: 8:00 AM-9:30 AM Room 210G (San Jose Convention Center) Francis Chan, Oregon State University, Corvallis, OR Hypoxia has garnered attention with dramatic die offs and devastated fisheries. Ocean acidification has not yet caused the same headline-grabbing effects, but is often mooted as a grave threat to marine ecosystems worldwide. Chemically, […]

Meeting: “Why Is the West Coast special? Acidification, hypoxia, and oceanographic connections”, AAAS 2015 Annual Meeting, San Jose, CA

Sunday, 15 February 2015: 8:00 AM-9:30 AM Room 210G (San Jose Convention Center) Tessa Hill, University of California, Davis, CA Ocean acidification is a global phenomenon of changes in ocean chemistry associated with anthropogenic carbon dioxide emissions to the atmosphere. Show More Summary

China's Productivity is Slowing Down

THE growth of China’s economy is staggering: it produced $9.5 trillion-worth of goods and services in 2013, nearly three times more than in 2007. But has that growth come simply from deploying more labour and capital? Or did total factor...Show More Summary

Science Online Died. Why?

Science Online was an amazing annual unconference that started a few years back and grew and became part of the reshaping of public communication about science. This year, the people running the conference started out with the plan to move the conference to a new venue, Atlanta, and last week abruptly announced that the conference…

Solve the Climate Crisis – Reelect Scott Peters in California’s 52nd

This is an endorsement by Climate Hawks Vote, which I support. Climate Hawks Vote is delighted to endorse Scott Peters in California’s 52d Congressional District of San Diego for his strong climate leadership and for taking first place in our August 2014 survey. And his approach just may break partisan gridlock in Congress. Scott Peters…

Whales Can Only Taste Salty

Five basic types of taste exist: sweet, sour, salty, bitter, and umami. Most people are familiar with all of these except the last, umami, which is best described as a pleasant savory taste. These tastes occur because of receptors that occur on cells in the mouth. Genes dictate the presence and number of these cells […]

First person in US to catch Ebola: The Meaning of Ebola Patient Two

The first person ever to catch Ebola in the United States is now in isolation at Texas Health Presbyterian Hospital. Don’t panic, even if you live in Dallas. But also, don’t fall into the hyperskeptical trap of assuming that because scientific authorities tell you everything is fine that concern is irrational. There are very rational…

NewLink Genetics, of Ames Iowa, Implicated in African Ebola Genocide?

According to those intimately involved in the response to the West African Ebola outbreak, NewLink Genetics owns the rights to a piece of the puzzle needed to quickly test and deploy one of two likely Ebola vaccines and they are holding up the entire process because they are not entirely sure they are going to…

Humans being loud under water, Cuttlefish

Last June (and May and July and part of August) we had a lot of precipitation in Minnesota. This caused lake levels to rise modestly. One lake, which is large enough to have meaningful waves, has older settlement along it so lots of cabins, boat houses, and such are right on the shoreline. With the…

The mysterious case of the missing manta bits

This spectacular picture has been doing the rounds of my Facebook network lately, of a Mr Bell at AMNH working on a manta ray specimen in 1917:   Woah, right?  Helluva fish.  Well, hold your horses there, Tex.  It’s actually a model.  I was a bit suspicious that the specimen was just so…perfect…so I dug around […]
