Clue To Smell Of Ancient Earth Given By Fossils
2013-04-29 15:23:27

University of Oxford Tiny 1,900 million-year-old fossils from rocks around Lake Superior, Canada, give the first ever snapshot of organisms eating each other and suggest what the ancient Earth would have smelled like. The fossils, preserved in Gunflint chert, capture ancient microbes in the act of feasting on a cyanobacterium-like fossil called Gunflintia — with the perforated sheaths of Gunflintia being the discarded leftovers of this early meal. A team, led by Dr David Wacey...

3-year study offers new evidence about where scientists should be looking A structural biologist at the Florida State University College of Medicine has made discoveries that could lead scientists a step closer to understanding how life first emerged on Earth billions of years ago. Professor Michael Blaber and his team produced data supporting the idea that 10 amino acids believed to exist on Earth around 4 billion years ago were capable of forming foldable proteins in a high-salt...

Predictability is often used synonymously with “boring,” as in that story or that outcome was so predictable. For practitioners of synthetic biology seeking to engineer valuable new microbes, however, predictability is the brass ring that must be captured. Researchers with the multi-institutional partnership known as BIOFAB have become the first to grab at least a portion of this ring by unveiling a package of public domain DNA sequences and statistical models that greatly...

Hyper And Micro-gravity Affect Processes Involved In Reproduction, Brain Diseases And Cancer
2013-03-14 12:12:58

University of Montreal University of Montreal researchers found that changes in gravity affect the reproductive process in plants. Gravity modulates traffic on the intracellular "highways" that ensure the growth and functionality of the male reproductive organ in plants, the pollen tube. "Just like during human reproduction, the sperm cells in plants are delivered to the egg by a cylindrical tool. Unlike the delivery tool in animals, the device used during plant sex consists of a single...

DNA Of Ancient Microorganisms Provide Clues On Origins Of Life
2013-03-08 11:41:26

April Flowers for redOrbit.com - Your Universe Online Important genetic clues about the history of a group of ancient microorganisms called archaea and the origins of life itself have been discovered by a team of researchers. Results of this first-of-its-kind study shed light on one of Earth's oldest life forms. "Archaea are an ancient form of microorganisms, so everything we can learn about them could help us to answer questions about the origin of life," explained William Whitman,...

Comets May Have Seeded Life On Earth

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Where did we come from? It is the question that has faced scientists, theologians and philosophers for millennia. And even in this age of technology, we have yet to stumble across the answer. One of the challenges is that it seems that living cells are difficult to make. Not only are they relatively complex structures, but also putting them together in such a way as to put into motion a metabolic system that can take...

Research uncovers a virus which infects a host that has a non-standard nuclear genetic code Among eukaryotes with modified nuclear genetic codes, viruses are unknown. Until now it had been believed that the modifications to the genetic code effectively prevented new viral infections. However, researchers have now reported the first example of a virus that can be shown to have crossed the boundary from organisms using the standard genetic code to those with an alternate genetic code....

The circadian clocks that control and influence dozens of basic biological processes have an unexpected "snooze button" that helps cells adapt to changes in their environment. A study by Vanderbilt University researchers published online Feb. 17 by the journal Nature provides compelling new evidence that at least some species can alter the way that their biological clocks function by using different "synonyms" that exist in the genetic code. "This provides organisms with a novel and...

Oceans Have Been The Stage For Earth's Longest Ongoing Battle Between Bacteria And A Virus
2013-02-14 13:55:19

April Flowers for redOrbit.com - Your Universe Online A new study led by Oregon State University reveals that the greatest battle in Earth's history has been going on for hundreds of millions of years. And the battle, which no one knew existed until now, is far from over. The findings of this study were published in a recent issue of Nature. On one side of the battle lines stands SAR11, a bacterium that´s the most abundant organism in the oceans, surviving where most other cells...

Scientists hope that one day in the distant future, miniature, medically-savvy computers will roam our bodies, detecting early-stage diseases and treating them on the spot by releasing a suitable drug, without any outside help. To make this vision a reality, computers must be sufficiently small to fit into body cells. Moreover, they must be able to "talk" to various cellular systems. These challenges can be best addressed by creating computers based on biological molecules such as DNA or...

Biology is the study of living organisms. Before the 19th century, biology was known as natural history (the study of all living things). Gottfried Reinhold Treviranus was the first person to coin the term biology. Biology comes from the Greek words bios (meaning "life") and logia (meaning "study of"). It is a common science that is a standard subject in schools and universities around the world. Over a million papers are published annually in biology and medicinal journals. Not just a...
