Evolution Of Complex Brains
2012-10-11 04:52:39

April Flowers for redOrbit.com - Your Universe Online Anatomically complex brains evolved earlier than previously thought and have changed little over the course of time, according to a new study by University of Arizona neurobiologist Nicholas Strausfeld. The specimen described in the study, which will be published in the October 11 issue of Nature, is the earliest known fossil to show a brain. The three inch long fossil was discovered embedded in mudstones deposited during the...

With less than two months before Election Day, AGI and its federation of 50 professional geoscience societies have come together again to provide a list of critical issues and policy recommendations for the next presidential administration. The document, Critical Needs for the Twenty-first Century: the Role of the Geosciences, is meant to inform policymakers of the unique knowledge, experience, and ingenuity of the geoscience community, and to address some of society's most pressing issues....

Resting in the Karakoram Range between northern Pakistan and western China, the Karakoram glaciers are stumping scientists. Unlike most mountain glaciers, the Karakoram glaciers, which account for 3 percent of the total ice-covered area in the world, excluding Greenland and Antarctica, are not shrinking. On the contrary, a team of French glaciologists has recently confirmed that these glaciers on average have remained stable or may have even grown slightly in recent years. Although all...

What are today's biggest unanswered questions in earth science? In the July issue of EARTH Magazine, experts from a variety of disciplines weigh in on what they consider to be the biggest unsolved mysteries across the geosciences and how they think we may solve them. Of course, in science, answering one question typically floods the field with new questions and thus new lines of investigation. For example, the discovery in the mid-19th century that carbon dioxide traps heat in Earth's...

The American Geosciences Institute has released Geoscience Currents 60, which examines female enrollments and degrees in the geosciences over time. In 2011, the Current concludes, female participation in U.S. geoscience degree programs remained generally steady. After decades of steady growth in the rate of female participation, there has been little change since 2005. Several interesting trends are also noted, including declines in doctorates awarded following economic downturns, and that...

AGI conducted a follow-up study to research conducted by Houlton (Geoscience Currents 45-48) in a Geoscience Currents series that examines the various pathways taken by undergraduate geoscience majors when deciding to concentrate in the Earth sciences. Conducted in late 2011, the new follow-up study featured in Geoscience Currents 57 utilizes data from 13 of the original 17 participants and discusses the similarities and differences between population groups in the context of their changing...

State Of Himalayan Glaciers Less Alarming Than Feared
2012-04-20 08:21:58

Ever since the false prognoses of the Intergovernmental Panel on Climate Change (IPCC), the Himalayan glaciers have been a focus of public and scientific debate. The gaps in our knowledge of glaciers in the Himalayan region have hindered accurate statements and prognoses. An international team of researchers headed by glaciologists from the University of Zurich and with the involvement of scientists from Geneva now outlines the current state of knowledge of glaciers in the Himalayas in a...

Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

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,...
