explaining the Last Glacial Maximum
2014-06-03 05:48:44

redOrbit Staff & Wire Reports - Your Universe Online A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well...

Baltic Amber Deposits Reveal A New Species Of Flat Bug
2014-06-02 03:01:02

Pensoft Publishers A piece of Eocene Baltic Amber of about 45 million years age contains a well preserved extinct flat bug, which turned out to be a new species to science. This exciting discovery is one of the many secrets that deposits of Baltic amber have revealed in the last years and are yet to come in the future. The study describing the new species was published in the open access journal Deutsche Entomologische Zeitschrift. The new species Aradus macrosomus is a rather large...

Antarctic Ice Sheet Became Unstable At The End Of The Last Ice Age
2014-05-29 05:20:26

redOrbit Staff & Wire Reports - Your Universe Online The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature. The study, which comes in the wake of research suggesting that destabilization of some of the West Antarctic Ice Sheet has already begun, also said that the shrinkage of the ice sheet accelerated and caused rapid sea level...

New Techniques For Visualizing Fossils Are Transforming Our Understanding Of Evolutionary History
2014-05-23 03:35:03

University of Bristol Palaeontology has traditionally proceeded slowly, with individual scientists laboring for years or even decades over the interpretation of single fossils which they have gradually recovered from entombing rock, sand grain by sand grain, using all manner of dental drills and needles. The introduction of X-ray tomography has revolutionized the way that fossils are studied, allowing them to be virtually extracted from the rock in a fraction of the time necessary to...

New Fossil Organism Discovered By Paleontologists
2014-05-12 03:23:48

By Iqbal Pittalwala, University of California - Riverside Likely related to our ancestors, 'Plexus ricei' was much like a tapeworm or modern flatworm, say UC Riverside researchers Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time. Named Plexus ricei and resembling a curving tube, the organism resided on the Ediacaran...

Evolution Of Smaller Dinosaurs Helped Their Lineage Survive As Birds
2014-05-07 09:53:08

Brett Smith for redOrbit.com - Your Universe Online While dinosaurs may have disappeared from the face of the Earth, their lineage has survived in the form of birds and new research published in the journal PLOS Biology has found that both dinosaurs and birds evolved into smaller and smaller sizes – potentially contributing to their success. “Dinosaurs aren't extinct; there are about 10,000 species alive today in the form of birds,” said study author Roger Benson, a paleobiologist...

April Flowers for redOrbit.com - Your Universe Online Climatologists use deep-drilled ice core samples in order to understand the climate changes our planet has endured during and between the Ice Ages. A team of scientists has recently developed a new technique, described in the Proceedings of the National Academy of Sciences, to confirm the age of a 120,000-year-old sample of Antarctic Ice. Scientists will be able to use the new dating technique to identify ice that is much older,...

Understanding How Climatic Relationships Led To Major Ice Age Cycles
2014-04-17 07:45:44

April Flowers for redOrbit.com - Your Universe Online A new study has developed crucial new information about how the ice ages came about based on newly discovered relationships between deep-sea temperature and ice-volume changes. The international team of researchers, led by the University of Southampton, developed a new method for determining sea-level and deep-see temperature variability over the past 5.3 million years. Their findings were published in a recent issue of Nature. The...

Researchers Find Rare Fossilized Embryos More Than 500 Million Years Old
2014-04-11 13:06:23

Jeff Sossamon, University of Missouri The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record. Also dubbed the “Cambrian explosion,” fossilized records from this time provide glimpses into evolutionary biology when the world’s ecosystems rapidly changed and diversified. Most fossils show the organisms’ skeletal structure, which may or may not give researchers accurate pictures of these prehistoric organisms. Now, researchers at the...

Hula Painted Frog, Discoglossus nigriventer
2014-08-18 15:55:22

The Hula painted frog was considered extinct by the IUCN since 1996. Very little is known about the species because very few specimens have been found. In 1940 two adults and two tadpoles were collected but the smaller one was eaten by the larger one, and the tadpoles were lost. A single Hula painted frog was found in 1955 which was the last record of this specimen. The extinction of this species is said to be the result of the draining of lake Hula and its marshes in the 1950’s. Only...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Geologic Clock With Events And Periods
2012-11-18 19:10:56

The Neoproterozoic is the third of three subdivisions of the Proterozoic Eon (occurring from 1 billion years ago to 542 million years ago). This terminal era of the Proterozoic is itself divided into three sub-periods called the Tonian, Cryogenian, and Ediacaran Periods. The most severe glaciation known in the geologic record occurred during the Cryogenian Period, when ice sheets reached the equator and formed a possible “Snowball Earth.” And the earliest fossils of multi-cellular life...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
