Effective Stress - Part 4

Ok, enough of the basics, it'll just zoom over the heads of all those 'non-math' scientists who seem to control our lives through oral skills. Let's get down to injection.  If I insert my hose into a bed of clay, nothing much happens.  The water stops, since the clay is impermeable, that is, a very low permeability.  I can pump up the water, which produces a very high pressure gradient in

Significance of bizarre exteinct creature revealed

A bizarre extinct creature that has mystified scientists since its 500m-year fossil was first unearthed more than a century ago has finally revealed its teeth – placing it centre stage in the evolution of many complex life-forms living today.Hallucigenia, which owes its name to its unworldly appearance, was so odd that scientists initially confused its top from its bottom and its head from its tail. However, a study has now unequivocally identified its mouth, complete with a fearsome ring of [...]

Glacial Earthquakes May Help Forecast Sea-Level Rise

It is only recently that scientists learned of the existence of glacial earthquakes–seismic rumblings produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. In Greenland, where they have been extensively measured, such quakes have grown sevenfold over the last two decades and they are advancing northward. This suggests that ice loss is increasing

Humans have an overabundance than 99 problems and scientists have just pushed water higher up their email list. A new study conducted by scientists in the University of California signifies that a third from the world’s biggest groundwater sources are under stress — which essentially shows that our demand is exceeding nature’s supply.

An Online Course Every High School Science Student Should Take

John Cook at the University of Queensland (along with others) has produced a very good course about climate change and its denial. He also covers the consensus among scientists, and why the claims by the deniers are so laughably wrong. I keep up with the research, and have read a lot about the psychology behind why people will refuse to accept the obvious, but I still learned quite a few things I did

World’s Oldest Unused Stone Tools Found (So They Say)

Last week, it was announced that scientists had found the world's oldest stone tools, in Kenya, dated at 3.3 million years. The precise dating of the tools was made possible by Chris Lepre and Dennis Kent of Lamont-Doherty Earth Observatory, who used periodic reversals in earth's magnetic field to nail the timing. Now, in a related study, a separate team says they have discovered the world's oldest stone tools that were never used--an apparent revelation about early human leisure

GeoEd: Why So Serious?

In this edition of GeoEd, Sam Illingworth, a lecturer in science communication at Manchester Metropolitan University, explores the benefits of a more informal teching style and how the incorporation of play into everyday teaching can help to engage and enthuse students who oterhwise struggle to connect with the sciences. Despite the hard work, there are some real perks to being a scientists: field work, conferences, travelling, collaborations, etc… to name but a few. The key is to show [...]

It’s been just over a month since the EGU General Assembly 2015 in Vienna. The conference this year was a great success with 4,870 oral, 8,489 poster, and 705 PICO presentations. There were 577 unique scientific sessions, complimented by an impressive 310 side events, making for an interesting and diverse programme. The conference brought together 11,837 scientists from 108 countries, 23% of which were students. Keeping abreast of everything that was going on throughout the week was made [...]

Global Warming’s ‘Missing’ Heat: It May Be in the Indian Ocean

Since the late 1990s, global warming has stabilized, even as greenhouse gases have risen. That defies simple models that say the temperature should keep going up. Many scientists think the so-called “hiatus” is taking place in part because much of the heat trapped in the atmosphere by greenhouse gases is being soaked up and stored by the oceans–at least for
