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

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...

Tracing the tree of life back to a single ancestral form A study published in PLoS Computational Biology maps the development of life-sustaining chemistry to the history of early life. Researchers Rogier Braakman and Eric Smith of the Santa Fe Institute traced the six methods of carbon fixation seen in modern life back to a single ancestral form. Carbon fixation — life's mechanism for making carbon dioxide biologically useful — forms the biggest bridge between Earth's...

The traditional way of making medicines from ingredients mixed together in a factory may be joined by a new approach in which doctors administer the ingredients for a medicine separately to patients, and the ingredients combine to produce the medicine inside patients' bodies. That's one promise from an emerging new field of chemistry, according to the scientist who founded it barely a decade ago. Carolyn Bertozzi, Ph.D., spoke on the topic – bioorthogonal chemistry – here today...

A team of scientists has documented for the first time that animals can and do consume Archaea — a type of single-celled microorganism thought to be among the most abundant life forms on Earth. Archaea that consume the greenhouse gas methane were in turn eaten by worms living at deep-sea cold seeps off Costa Rica and the West Coast of the United States. Archaea perform many key ecosystem services including being involved with nitrogen cycling, and they are known to be the main...

Microbes Found Speciating In Russian Hot Spring
2012-02-22 09:04:50

[ Watch the Video ] It was Darwin who, upon studying evolving creatures, wondered how species diverge if they are living together. “That question really hasn´t been answered very well, even in the macro-organisms that we´ve studied for hundreds of years,” University of Illinois microbiology professor Rachel Whitaker ponders. Despite still being in close proximity to one another in an acidic, boiling habitat of a hot spring in Kamchatka, Russia, two groups of...

Chemists have taken an important step in making artificial life forms from scratch. Using a novel chemical reaction, they have created self-assembling cell membranes, the structural envelopes that contain and support the reactions required for life. Neal Devaraj, assistant professor of chemistry at the University of California, San Diego, and Itay Budin, a graduate student at Harvard University, report their success in the Journal of the American Chemical Society. “One of our long...

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...
