Land Life Earlier Than Thought
2013-07-22 14:37:42

Brett Smith for redOrbit.com - Your Universe Online Conventional theories have placed life on land for the last 500 million years, but a new study from a team of American and Australian researchers might push that back to 2.2 billion years. To support their claim, the scientists presented evidence in the form of tiny newly discovered fossils the size of a match head called Diskagma buttonii that were discovered in ancient soil samples. "They certainly were...

Community colleges provide a strong foundation for the nation's graduating STEM (Science Technology Engineering and Mathematics) workforce. In its latest Geoscience Currents, the American Geosciences Institute documents the flow of geoscience students from 2–year to 4-year institutions in Texas, adding to an earlier report on similar data from California released in 2012. In 2012, 70 percent of geoscience students in Texas public universities had transferred from...

Ancient Fish Fossils Give Insight Into Evolutionary History Of Gobioid Order
2013-05-16 13:51:46

LMU Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes. Researchers led by paleontologist Professor Bettina Reichenbacher from the Division of Paleontology and Geobiology at LMU´s Department of Earth and Environmental Sciences have completed a comprehensive analysis of fish fossils which they assign to the group of bony fishes that includes...

A team of geoscientists from Southwest Research Institute (SwRI) using newly available remote-sensing technology has achieved unprecedented detail in quantifying subtle, long-period changes in the water levels of shallow lakes and ponds in hard-to-reach Arctic wetlands. Analysis comparing time-lapsed, high-resolution satellite imagery of the Ahnewetut Wetlands in Kobuk Valley National Park, Alaska, revealed an accelerated loss of surface water in shallow thaw lakes and ponds over a recent...

In the March issue of GSA Today, seven scientists from six countries, led by Jan Zalasiewicz of the University of Leicester, propose a realignment of the terms "geochronology" and "chronostratigraphy" in an attempt to resolve the debate of whether units of the Geological Time Scale should have a single (time) or dual (time and time-rock) hierarchy. In their system, which retains both parallel sets of units, with an option to adopt one or other when appropriate, geochronology refers to all...

Jurassic Records Warn Of Risk From Global Warming On Marine Life
2013-02-19 14:08:45

Plymouth University Researchers at Plymouth University, UK, believe that findings from fieldwork along the North Yorkshire coast reveal strong parallels between the Early Jurassic era of 180 million years ago and current climate predictions over the next century. Through geology and palaeontology, they've shown how higher temperatures and lower oxygen levels caused drastic changes to marine communities, and that while the Jurassic seas eventually recovered from the effects of global...

Mapping Forest Biomass To Understand The Global Carbon Cycle
2013-02-05 10:54:59

ESA Satellite radar data are being used to map Earth´s vital resources. The latest advances and applications of the POLinSAR remote sensing technique were highlighted at a conference held last week. Polarimetric InSAR — or POLinSAR — is a remote sensing technique based on polarimetric information in Synthetic Aperture Radar (SAR) images. With this technique, a radar sends polarised pulses towards the target, and the information in the signals backscattered from Earth...

Jurassic Ecosystem
2013-01-09 06:26:57

Rayshell Clapper for redOrbit.com - Your Universe Online According to Southern Methodist University paleontologists Timothy S. Myers, Louis L. Jacobs, and SMU sedimentary geologist Neil J. Tabor, the modern relationship between animals and vegetation is similar to millions of years ago. In their study, the SMU scientists used fossil soils from the Late Jurassic age gathered from locations where animal fossils were previously found to determine the levels of carbon isotopes. The team...

Environmental Science
2014-01-12 00:00:00

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
