A Short Summary of Nares Strait Physics

by Andreas Muenchow in Icy Seas

The Arctic Ocean is a puddle of water covered by ice that melts, moves, and freezes. Grand and majestic rivers of Siberia and America discharge into the puddle and make it fresher than Atlantic Ocean waters. The fate of the … Continue reading →... Read more »

Live Fast, Die Young: Evolutionary Outcomes of an Asteroid Impact

by Melissa Chernick in Science Storiented

A new semester has started and with it an influx of new students into the lab has begun. Busy has become my middle name. So when I was looking around for a paper to write about I wanted something different and cool. Not exactly hard to find in science. The asteroid known as 2012 DA14 will narrowly miss Earth this Friday, the closest known asteroid flyby on record. And by close we’re talking within the orbits of many communications satellites. This got me thinking about and looking for recent p........ Read more »

Corals Engineer Their Own Currents

by Elizabeth Preston in Inkfish

There are few more monastic lives in the animal kingdom than a coral’s. In adulthood it gives up swimming to settle on the ocean floor, surround its spineless body with clones, and become a rock. Mouth facing the ocean, it waits passively for whatever drifts by—or maybe not so passively. Taking a closer look at […]The post Corals Engineer Their Own Currents appeared first on Inkfish....

Global Warming Denial: Common Arguments and Misconceptions

by Alexis Delanoir in How to Paint Your Panda

An informal collection of common arguments and misconceptions by global warming denialists, as well as my rebuttals. Uses relevant data from IPCC, NOAA, NASA and peer-reviewed literature. Its purpose serves to inform the general public about these false claims so that we can escape this bout with pseudoscience a bit faster.... Read more »

East Greenland Current Instabilities

by Andreas Muenchow in Icy Seas

The coast off north-east Greenland is a grey, cloudy, and icy place. I spent 4 weeks on a ship earlier this summer to place sensors on the ocean floor to measure water currents, salinity, and temperature. The data shall uncover … Continue reading →... Read more »

These Cave Rocks Are Made out of Bacteria

by Elizabeth Preston in Inkfish

Stalactites hold tight to the ceiling, the saying goes, and stalagmites might grow high enough to reach it. But the simple mnemonic doesn’t come close to covering the variety of weird, rocky shapes growing all over a cave. There are even, it turns out, rocks made from bacteria. They’re not putting the “tight” in “stalactite” so […]The post These Cave Rocks Are Made out of Bacteria appeared first on Inkfish.... Read more »

Swamp Thing and Plant Communication

by Gabriel in Lunatic Laboratories

Maybe I’m dating myself here, but ever see the swamp thing movie, television show, or even the comic? Call me picky, after all we are talking about a human/plant hybrid, but he never needed to talk. I know, some of you are probably rolling your eyes at me given it’s a comic, movie or tv show [depending on your level of geek], but come on, this is science![…]... Read more »

Few but strong: dense tornado clusters on the rise in the United States

Competition for ecological niches limits evolution of new species | @GrrlScientist

by GrrlScientist in GrrlScientist

A recently published study finds that competition for ecological niches limits the evolution of new species. Further, this study finds that speciation rate slows or even stops as available ecological niches fill up. Continue reading...... Read more »

Earth’s energy imbalance

by Ed Hawkins in Climate Lab Book

Weather Vs. Climate In Global Warming

by Mark E. Lasbury in The 'Scope

Last winter was horrible, and this summer has been mild – so global warming must not be real. This is the thought process for many people, but it points out the confusion between climate and weather. Climate is the average weather for a place over a given period, while weather is what you get day to day. New research is showing that climate change is causing more intense hurricanes - but is the number changing? Recent studies land on both sides of the issue.... Read more »

Metamorphic petrology: under pressure and getting stressed?

by Metageologist in Metageologist

High pressure (HP) terranes are areas containing eclogites and other eclogite-facies rocks found within many mountains belts, including the Himalaya and the Alps. HP rocks were metamorphosed at extreme pressures, up to 3 or even 4 billion Pascals (or GPa. Atmospheric … Continue reading →... Read more »

Wet get drier (eventually)?

Temperatures make our global warming opinions change like the weather

Top-of-atmosphere contribution to unforced variability in global temperature

by Ed Hawkins in Climate Lab Book

As the attention received by the ‘global warming hiatus’ demonstrates, global mean surface temperature (T) variability on decadal timescales is of great interest to both the general public and to scientists. Here, I will discuss a recently published paper (Brown … Continue reading →... Read more »

Optical Cables, from Thin Air!

by Gabriel in Lunatic Laboratories

It’s a project that would make Tesla proud. Just imagine being able to instantaneously run an optical cable or fiber to any point on earth, or even into space. That’s what researchers are trying to do. Did I mention it was instantaneous and involved no connection other than the air around us? Well if you are as excited as I am, then you should read on! If not, two words, laser weapons!!... Read more »
