Algae Held Captive And Their Genes Stolen In Crime Of Evolution
2012-11-28 15:38:41

University of Melbourne Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature. The results reveal a 'missing link' in evolution because the tiny animal thieves (protozoa) couldn't completely hide all evidence of the captive algae, and have been effectively frozen in time and caught in the act by genetic sequencing....

Multicellular bacteria transmit electrons across relatively enormous distances A multinational research team has discovered filamentous bacteria that function as living power cables in order to transmit electrons thousands of cell lengths away. The Desulfobulbus bacterial cells, which are only a few thousandths of a millimeter long each, are so tiny that they are invisible to the naked eye. And yet, under the right circumstances, they form a multicellular filament that can transmit...

Experimental studies of ancestral visual pigments and their mutational variants cast doubt on simplifying assumptions widely used in evolutionary studies of proteins A key assumption that biologists have relied on widely over the past quarter-century in studying the evolution of protein molecules is "highly questionable," according to an article published in the November issue of BioScience. The article, by Shozo Yokoyama, a vision researcher at Emory University, summarizes experimental...

A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study reshapes the universal family tree, adding a fourth major branch to the three that most scientists agree represent the fundamental domains of life. The new findings appear in the journal BMC Evolutionary Biology. The researchers used a relatively new method to peer into the distant past. Rather than comparing...

Mechanism Discovered in Deep Ocean Production Of Methane
2012-08-31 13:17:05

Brett Smith for redOrbit.com - Your Universe Online While searching for new and more effective antibiotics, a team of biologists and chemists has stumbled upon the mechanism responsible for the deep ocean production of methane, a greenhouse gas that drives climate change. Researchers from the University of Illinois and the University of Washington began their studies examining microbes´ production of phosphonates that these tiny creatures use to disrupt bacteria and other...

Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...

The Annual Meeting of the American Crystallographic Association (ACA) will be held July 28 — Aug. 1, 2012, at the Westin Waterfront Hotel in Boston, Mass. Crystallography is the science devoted to exploring the arrangement of atoms in regular crystalline solids and in complicated molecules. Scientists will present research spanning a diverse array of disciplines, including medicine, genomics, material science, and structural biology. The following summaries link to full news releases...

Computer Model Maps Organism's Entire Lifespan Completed
2012-07-22 08:08:31

redOrbit Staff & Wire Reports - Your Universe Online In what is being called "a breakthrough effort for computational biology," researchers from a pair of US universities have successfully completed a software model of an organism's entire lifespan. The research, which was led by Stanford University Assistant Professor of Bioengineering Markus Covert, used data obtained from over 900 previous scientific papers in order to account for every molecular interaction that occurs during...

Scientists Create Rewritable DNA
2012-05-22 13:29:59

Scientists have found a way to create rewritable digital data storage in DNA through means similar to binary coding. The researchers worked to reapply natural enzymes adapted from bacteria to flip specific genetic sequences of DNA back and forth at will. The scientists, who all work in the Department of Bioengineering at Stanford University Medical Center, said their method essentially works like that of binary computer coding. "Essentially, if the DNA section points in one...

Queen Of Spades Key To New Evolutionary Hypothesis
2012-05-11 03:02:13

Microscopic ocean plankton mimic card also known as the Black Queen Sleight of hand is a trait that belongs mainly to humans. Or so scientists thought. Studies of common, microscopic ocean plankton named Prochlorococcus show that humans aren't the only ones who can play a mean game of cards. Their method lurks in the Black Queen Hypothesis, as it's called, after the Queen of Spades in the card game Hearts. Scientists Jeffrey Morris and Richard Lenski of Michigan State...

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...
