New results in the field of RNA research establish that the RNA splicing factor SF2/ASF can act as a cancer-causing protein by changing the alternative splicing of other genes critical for growth-control of cells.

Targeting the adrenal gland could be key strategy against heart failure, Jefferson scientists show
Scientists have staved off heart failure in animals by using gene therapy to shut down the adrenal gland's excessive output of fight or flight hormones such as epinephrine and norepinephrine, which forces the heart to pump too hard.

University of Rochester scientists, while investigating the two most frequent types of mutations in cancer, discovered a possible new route to treatment that would take advantage of the mutations instead of trying to repair them.

'Ten Commandments' could improve fisheries management
Poorly managed marine fisheries are in trouble around the world, researchers say, while ecosystem-based management is a powerful idea that in theory could help ensure sustainable catches -- but too often there's a gap in translating broad concepts into specific action.

Genome scan for familial autism finds two new genetic links
The first results from a scan of the world's largest collection of DNA samples from families affected by autism point to two new genetic links that may predispose people to the brain disorder.

New research aimed at understanding the link between carbon dioxide emissions and climate change in boreal systems has found clear links between both spring and fall temperature changes and carbon uptake/loss.

Clemson research improves inkjet technology
Research from Clemson University shows that producing cardiac tissue with off-the-shelf inkjet technology can be improved significantly with precise cell placement.

RNAi shows promise in gene therapy, Stanford researcher says
Three years ago Mark Kay, MD, PhD, published the first results showing that a biological phenomenon called RNA interference could be an effective gene therapy technique.

Tackling climate change will require expertise from several fields, Carnegie Mellon professor says

UI researcher cites need for a 'small view' of the environment
By thinking small, scientists can solve big environmental problems. That is the message University of Iowa researcher Vicki H.

Fetal heart-cell enzyme important in onset of heart failure
In almost all forms of heart failure, the heart begins to express genes that are normally only expressed in the fetal heart.

Cancer cells more likely to genetically mutate
When cells become cancerous, they also become 100 times more likely to genetically mutate than regular cells, researchers have found.

Long-lived deep-sea fishes imperiled by technology, overfishing
Many commercially prized fish from the depths of the world's oceans are severely threatened by over-fishing and the species' ability to recover is constrained by the fishes' long lifespans and low reproductive success, a panel of experts said today at the annual meeting of the American Association of the Advancement of Science.

Largest genomic search finds genes that may contribute to autism
An international team of researchers from 19 countries has identified one gene and previously unidentified region of another chromosome as the location of another gene that may contribute to a child's chances of having autism.

ASU researcher finds belief about neighbor's conservation is stealthily influential
If everyone jumped off a bridge, would you? Probably not, but according to a study by Arizona State University researchers, peer influence plays a greater role in people's behavior than is generally acknowledged.

Public agrees global warming exists, but divided over seriousness of problem
A majority of Americans agree with most scientists that the Earth is getting warmer, but they are divided over the seriousness of the problem, according to surveys conducted by Jon Krosnick, professor of communication and of political science.
