Men are 50 per cent more likely to get esophageal cancer than 30 years ago

Posted: 06 Jun 2015 05:41 PM PDT

Esophageal cancer rates in men have increased by 50 per cent since the early 1980s. In women, the increase is much smaller with around 10 per cent more now developing the disease compared to the 80s, research shows.

Current mobile contracts damaging the environment

Posted: 06 Jun 2015 05:40 PM PDT

Researchers analyzed studies on the lifespan of mobile devices, from manufacture, use and disposal to see what impact each stage had on the environment. Through their investigation, they concluded that the current mobile business model, driven by frequent upgrades, is costing both the manufacturer and the environment. The study argues that where frequent upgrades are encouraged and recycling schemes not actively pursued, valuable materials integral to phone manufacture are lost, causing damage to the environment by additional waste to landfill as well as from the impact of extracting additional finite resources.

Research reveals key interaction that opens the channel into the cell's nucleus

Posted: 05 Jun 2015 03:29 PM PDT

Scientists have uncovered crucial steps in the dynamic dance that dilates and constricts the nuclear pore complex -- the latest advance in their ongoing efforts to tease apart the mechanism by which its central channel admits specific molecules. Their work has shown that the nuclear pore complex is much more than the inert structure it was once thought to be.

New strategies for stopping the spread of Staph and MRSA

Posted: 05 Jun 2015 03:29 PM PDT

Staphylococcus aureus -- better known as Staph -- is a common inhabitant of the human nose, and people who carry it are at increased risk for dangerous Staph infections. However, it may be possible to exclude these unwelcome guests using other more benign bacteria, according to a new study.

Diverse coral communities persist, but bioerosion escalates in Palau's low-pH waters

Posted: 05 Jun 2015 03:28 PM PDT

The coral reefs in Palau seem to be defying the odds, showing none of the predicted responses to low pH except for an increase in bioerosion -- the physical breakdown of coral skeletons by boring organisms such as mollusks and worms.

As baby boomers age, do their decisions get better or worse?

Posted: 05 Jun 2015 03:23 PM PDT

As an economic and political force, researchers say that older adults hold a tremendous amount of social power in the United States. A new study is examining what factors contribute to older adults' decisions.

New data on botulinum toxin as treatment for nerve pain

Posted: 05 Jun 2015 03:23 PM PDT

Botulinum toxin could offer an effective new treatment for two forms of neuropathy—pain caused by different types of nerve injury, according to an experimental study.

Fruit fly genetics reveal pesticide resistance, insight into cancer

Posted: 05 Jun 2015 03:19 PM PDT

The miniscule and the massive have been bridged in an effort to better understand the mechanisms behind several unique features of fruit fly genes. Some of these genes also shed light on the evolution of pesticide resistance.

Precise transplant of a biomolecule to a synthesized molecule

Posted: 05 Jun 2015 05:24 AM PDT

The self-assembly of organic molecules and transition-metal ions afforded a well-defined, world's largest spherical molecule just by mixing the starting materials. Now researchers explain in a new article how cyborg supramolecule reveals the origin of pathogenic materials.
