Scientists Engineer First Living Organism with an Expanded Genetic Alphabet

May 8, 2014

1 Comment

A newly published study details how researchers at The Scripps Research Institute were able to create the first living organism with an expanded genetic alphabet. Scientists at The Scripps Research Institute (TSRI) have engineered a bacterium whose genetic material includes an added pair of DNA “letters,” or bases, not found in nature. The cells of […]

Study Shows Nanoparticles in Consumer Products Can Damage DNA

April 9, 2014

2 Comments

Using high-speed screening technology to analyze DNA, a newly published study found that nanoparticles commonly added to consumer products can significantly damage DNA. Thousands of consumer products — including cosmetics, sunscreens, and clothing — contain nanoparticles added by manufacturers to improve texture, kill microbes, or enhance shelf life, among other purposes. However, several studies have […]

MIT Researchers Reverse a Rare Liver Disorder in Mice

April 3, 2014

1 Comment

In a newly published study, MIT researchers show that a new gene-editing technique, known as CRISPR, can reverse a rare liver disorder caused by a single genetic mutation. Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation. The findings, […]

Regular Exercise Induces Changes in DNA

August 1, 2013

1 Comment

A study from scientists at Lund University found that exercise induces genome-wide changes in DNA methylation in human adipose tissue, potentially affecting adipocyte metabolism. Exercise, even in small doses, changes the expression of our innate DNA. New research from Lund University in Sweden has described for the first time what happens on an epigenetic level […]

In a newly published study, an international team of researchers detail the search for “microbial dark matter.” Is space really the final frontier, or are the greatest mysteries closer to home? In cosmology, dark matter is said to account for the majority of mass in the universe, however its presence is inferred by indirect effects […]

DNA Study Reveals Clues about Primate Evolution

July 17, 2013

1 Comment

In a new DNA study, an international team of scientists reveal clues to human and ape evolution, finding that the evolutionary history of ancestral great ape populations was far more complex than that of humans. A massive effort to catalog the genetic variation in humans, chimpanzees, gorillas and orangutans has helped researchers piece together a […]

Study Suggests Life on Earth is the Result of Icy Comets

June 6, 2013

1 Comment

A newly published study suggests that life on earth may have started as a result of icy comets that crashed into Earth billions of years ago. Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this […]

Preserved Mammoth with Blood Discovered in Siberia

May 29, 2013

1 Comment

A team of Russian scientists have discovered the remains of a female mammoth with blood and muscle tissue. Russian scientists have claimed to have discovered a fully-grown female mammoth carcass with blood and well-preserved muscle tissue trapped in ice in Siberia. The researchers found the mammoth blood during the excavation on the Lyakhovsky Islands in […]

Ancient DNA Reveals the First Detailed Genetic History of Modern Europe

April 24, 2013

2 Comments

An international team of researchers used ancient DNA to reconstruct the first high-resolution genetic record of modern European lineages through time, observing both human DNA evolving in ‘real-time’ and the dramatic population changes that have taken place in Europe. Ancient DNA recovered from a series of skeletons in central Germany up to 7500 years old […]

Telomere Length Predicts the Life Expectancy of Patients with Heart Disease

March 11, 2013

1 Comment

In a new study, scientists were able to predict survival rates among patients with heart disease based on the length of strands of DNA found on the ends of chromosomes known as telomeres. San Francisco, California – Can the length of strands of DNA in patients with heart disease predict their life expectancy? Researchers from […]

Ancient DNA Reveals Link between Early Humans & Present-Day Asians and Native Americans

January 22, 2013

0 Comments

Analyses of ancient DNA, which had been extracted from the leg bone of an early modern human living some 40,000 years ago near Beijing, revealed that this early modern human was related to the ancestors of many present-day Asians and Native Americans. An international team of researchers including Svante Pääbo and Qiaomei Fu of the […]

Study Shows Four-Stranded ‘Quadruple Helix’ DNA Structure in Human Cells

January 21, 2013

3 Comments

University of Cambridge scientists have published a new study showing that four-stranded ‘quadruple helix’ DNA structures, known as G-quadruplexes, exist within the human genome. In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving ‘double helix’ DNA structure – the chemical code for all life. Now, in the year of that scientific […]
