Sweetman: Has Boeing Already won the UCLASS Competition With its "P-AEA" Program "win?"

What’s going on with the Pentagon’s longest-running drama, the Navy’s Unmanned Carrier-Launched Airborne Surveillance and Strike (Uclass) program? After years of factional intrigue that made Borgia politics look like a Dick & Jane reader, the debate about Uclass specifications has been declared not over, but deferred. Show More Summary

20 Year old Military Satellite Experiences Unexplained Temperature Spike, Explodes

A 20-year-old military weather satellite apparently exploded in orbit Feb. 3 following what the U.S. Air Force described as a sudden temperature spike.The “catastrophic event” produced 43 pieces of space debris, according to Air Force Space Command, which disclosed the loss of the satellite Feb.

Theia Formed in the Same Region as the Earth

A primordial origin for the composition similarity between the Earth and the MoonAuthors:Mastrobuono-Battisti et alAbstract:Most of the properties of the Earth-Moon system can be explained by a collision between a planetary embryo and the growing Earth late in the accretion process.

Lost City, Rumored "City of the Monkey God," Discovered in Honduran Rain Forest

An expedition to Honduras has emerged from the jungle with dramatic news of the discovery of a mysterious culture's lost city, never before explored. The team was led to the remote, uninhabited region by long-standing rumors that itShow More Summary

Science Denialists Have Delayed Action On Climate Change: Soon vs. the Hockey Stick

If you have not been living in a cave, and had you been, I’d respect that, you know about Willie Soon Gate. Willie soon is a researcher on soft money at the Harvard Smithsonian Center for Astrophysics. Soon is well known for producing research of questionable quality that anemically attempts to buck the scientific consensus…

Diversity patterns of Devonian Plant Zosterophyllopsida Tied to PaleoGeography

Diversity patterns of the vascular plant group Zosterophyllopsida in relation to Devonian palaeogeographyAuthors:Cascales-Miñana et alAbstract:The Zosterophyllopsida originated in the Silurian and became prominent vascular components of Early Devonian floras worldwide. Show More Summary

The Hydraulic Hypothesis and the End of Civilization

OK, I admit the title of this post is possibly a bit extreme but I could not resist the symmetry. Here, I refer to both ends of civilization, the start and the finish. I’d like to talk about a recent review published in Science, titled “Systems integration for global sustainability” written by my colleague Peter…

Potential and limitations of finite element modelling in assessing structural integrity of coralline algae under future global change

Coralline algae are important habitat formers found on all rocky shores. While the impact of future ocean acidification on the physiological performance of the species has been well studied, little research has focussed on potential changes in structural integrity in response to climate change. A previous study using 2-D Finite Element Analysis (FEA), suggested increased […]

Physio-ecological responses of Patagonian coastal marine phytoplankton in a scenario of global change: Role of acidification, nutrients and solar UVR

The aim of our study was to experimentally determine the future combined effects of solar UVR (280–400 nm), nutrients enrichment and acidification on a natural phytoplankton community (late phase of the bloom) of the Chubut River estuary (Patagonia, Argentina). We exposed the community to two radiation conditions (i.e., with and without UVR) under a future […]

Physiological and ecological performance differs in four coral taxa at a volcanic carbon dioxide seep

Around volcanic carbon dioxide (CO2) seeps in Papua New Guinea, partial pressures of CO2 (pCO2) approximate those as predicted for the end of this century, and coral communities have low diversity and low structural complexity. To assess the mechanisms for such community shifts in response to ocean acidification, we examined the physiological performance of two […]

Scientists to deploy ocean cameras as acidification fears mount

Climate scientists are looking for a new perspective on the increasingly acidic oceans through a suite of satellites 700 km out in space, watching over parts of the seas that research ships cannot reach. They report in the journal Environmental Science and Technology that thermal cameras could measure ocean temperatures, while microwave sensors could measure […]

Ocean acidification changing key organisms which form the basis of the marine food chain, say Swansea University researchers

OCEANS and marine life face a more uncertain future because ocean acidification, caused by climate change, is altering the growth of the organisms which are the basis of the entire food chain at sea. That is the finding of a Swansea University-led research team. Ocean acidification has been described as “the other CO2 problem”, and is also caused […]

Ocean acidification with (de)eutrophication will alter future phytoplankton growth and succession

Human activity causes ocean acidification (OA) though the dissolution of anthropogenically generated CO2 into seawater, and eutrophication through the addition of inorganic nutrients. Eutrophication increases the phytoplankton biomass...Show More Summary

This is Bob. Bob Says hi. Oh no, Bob Died...and we ate him!

For my daughter's birthday, we went to Ocean Beach in San Francisco. It was her request, actually, and we, of course! forgot the sun screen. We had a blast. However, it seems Poseidon() is pleased with my daughter and offered up a surprise for us: we were playing at the water's edge when my daughter spotted something in the surf. Show More Summary

New Research Demonstrates Link Between Greenhouse Gas Pollution and Global Warming

New Research on the Effects of CO2 Pollution A paper just published in Nature reports on the direct measurement of the effects of human greenhouse gas pollution on the heating of the Earth’s atmosphere. This is empirical verification of anthropogenic global warming. Since the Industrial Revolution, when humans started polluting the Earth’s atmosphere with copious…

The Next Downshift

We've reached the next step in the blog transition I started back in November. Originally, I was going to do this at the end of March. Time crunches have dictated I pull this forward. Posts will now be done every two hours (9,11,1, 3 & 5). Show More Summary

Horny-Arsed Trilobites

Reconstruction of Ceratopyge, from here. Just a short post for today. The Ceratopygidae are a family of trilobites known from the Late Cambrian and Early Ordovician. The name of the type genus, Ceratopyge, means 'horned rump', and one...Show More Summary

How to Allow Interaction With Reality While in Virtual Reality

Augmented reality provides a live view of the real world with computer generated elements superimposed. Pilots have long used head-up displays to access air speed data and other parameters while they fly. Some smartphone cameras can superimpose computer-generated characters on to the view of the real world. Show More Summary
