Because Egypt: Return of the Grandiose MegaProjects

Architecture projects don't come much bigger or more challenging than building an entire new capital city from scratch, but that's what the Egyptian Government, Skidmore, Owings & Merril (SOM), and international group of investors Capital City Partners Limited intend with the Capital Cairo project.

So what do you call a group of cuttlefish?

Octopuses are generally loners. Squids often form schools. But cuttlefish (or seacuttles if you will)…they outright just don’t get along with one another. In the video below two Giant Australian Cuttlefish males that are bit cranky fight over a female. They are both flashing the characteristic Zebra “Don’t FK With Me” pattern.  Make sure you […]

Mesozoic Miscellany 73

In the News Meet Carnufex carolinensis, a new Triassic crocodylomorph that hit the web with a splash last week. Described by Lindsay Zanno and team in Scientific Reports, C. carolinensis was a massive, top-of-the-food-chain predator nicknamed "The Carolina Butcher." Co-author Susan Drymala discussed the find with BBC Radio's Up All Night. Show More Summary

Detecting the progression of ocean acidification from the saturation state of CaCO3 in the subtropical South Pacific

Progression of ocean acidification in the subtropical South Pacific was investigated by using high-quality data from trans-Pacific zonal section at 17°S (World Ocean Circulation Experiment section P21) collected in 1994 and 2009. During this 15-year period, the CaCO3 saturation state of seawater with respect to calcite (?cal) and aragonite (?arg) in the upper water column […]

Ocean acidification alters the calcareous microstructure of the green macro-alga Halimeda opuntia

Decreases in seawater pH and carbonate saturation state (?) following the continuous increase in atmospheric CO2 represent a process termed ocean acidification, which is predicted to become a main threat to marine calcifiers in the near future. Show More Summary

Prowling coral colonies, the Caribbean reef octopus (Octopus briareus) is built to blend in. This camouflage artist flashes through skin textures and shades of blue, green, red and brown—allowing it to sneak up and envelop prey in a gauzy web of tentacles. Get up close in our Tentacles exhibition

Centropages typicus (Crustacea, Copepoda) reacts to volatile compounds produced by planktonic algae

Volatile organic compounds (VOCs) may play the role of infochemicals and trigger chemotaxis and ecologically relevant responses in freshwater and marine invertebrates. Aquatic grazers use these signals as chemical cues to trace the presence of their food or to detect their predators. However, detailed data are still needed to fully understand the role of these […]

Science Museums: Cut Ties to Big Carbon, Kick Out The Kochs!

There is a letter signed by top scientists demanding that science museums cut all their ties to Big Fossil, and where appropriate, kick the Koch Brothers off their boards. The letter says, in part, As members of the scientific community we devote our lives to understanding the world, and sharing this understanding with the public.…

Reviews and syntheses: Responses of coccolithophores to ocean acidification: a meta-analysis

Concerning their sensitivity to ocean acidification, coccolithophores, a group of calcifying single-celled phytoplankton, are one of the best-studied groups of marine organisms. However, in spite of the large number of studies investigating...Show More Summary

How do bird species compete with each other?

This is one of those great examples of research you can probably use in an advanced biology classroom (high school) or intro college bio pretty effectively. It includes birds. It includes hormones. It includes evolution. What else is there, really? I did a very brief writeup on it here, and you can get the original…
