New Rochelle, NY, Sept. 22, 2017 -- Researchers added a scaffold/matrix attachment region (S/MAR) to a conventional adeno-associated virus (AAV) vector used for gene transfer, and the modified vectors were able to establish colonies and maintain long-term transgene expression in HeLa cells, as reported in Human Gene Therapy, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high energy cosmic rays -- whether they came from our galaxy or outside the Milky Way.

Are voters in new democracies so disenchanted with the political process that more and more are staying away from the polls?

After people vote, do they think they made the right choice? When they abstain, do they regret not voting?

New research by Université de Montréal political scientist André Blais and PhD students Fernando Feitosa and Semra Sevi answers those questions for the first time - and finds that in general, people who vote are very happy with their choice and those who abstain doubt they did the right thing.

A new study published in JNCI Cancer Spectrum finds that smoking negatively impacts long-term survival after breast cancer. Quitting smoking after diagnosis may reduce the risk of dying from breast cancer.

This study aimed to examine whether smoking at the time of diagnosis and changes in smoking within five years after diagnosis were associated with long-term breast cancer mortality.

Barcelona, 21 September 2017 - Cancer, which is one of the leading causes of death worldwide, arises from the disruption of essential mechanisms of the normal cell life cycle, such as replication control, DNA repair and cell death. Thanks to the advances in genome sequencing techniques, biomedical researchers have been able to identify many of the genetic alterations that occur in patients that are common among and between tumor types. But until recently, only mutations in DNA were thought to cause cancer.

We must move faster towards a low-carbon world if we are to limit global warming to 2oC this century, experts have warned.

Changes in electricity, heat, buildings, industry and transport are needed rapidly and must happen all together, according to researchers at the universities of Sussex, Manchester and Oxford in a new study published in the journal Science.

How did Neanderthals grow? Does modern man develop in the same way as Homo neanderthalensis did? How does the size of the brain affect the development of the body? A study led by the Spanish National Research Council (CSIC) researcher, Antonio Rosas, has studied the fossil remains of a Neanderthal child's skeleton in order to establish whether there are differences between the growth of Neanderthals and that of sapiens.

DETROIT - A novel psychological therapy that encourages addressing emotional experiences related to trauma, conflict and relationship problems has been found helpful for people with the chronic pain condition fibromyalgia. A research team led by Mark A. Lumley, Ph.D., distinguished professor of psychology in the College of Liberal Arts and Sciences at Wayne State University, in collaboration with a team from the University of Michigan Medical Center led by David A. Williams, Ph.D., professor of anesthesiology, has released the results of its research in the prestigious journal, PAIN.

WASHINGTON - Halting the opioid epidemic requires aggressive action across multiple dimensions, including informed, active, and determined front-line leadership from health clinicians working in every setting throughout the nation, says a new National Academy of Medicine (NAM) special publication developed at the request of the National Governors Association to assist the nation's governors as they work with clinicians to counter the opioid crisis.
