More accurate model for greenhouse gases from peatlands

Posted: 03 Oct 2014 06:43 PM PDT

Scientists have created a new model to more accurately describe the greenhouse gases likely to be released from Arctic peatlands as they warm.

Engineers use 3-D gaming gear to give eye-opening look at cells in action

Posted: 03 Oct 2014 06:43 PM PDT

For hundreds of years biologists have studied cells through the lens of a microscope. With a little help from a team of engineers, these scientists could soon be donning 3-D glasses in a home-theater-like lab to take their own fantastic voyage into the petri dish.

RCas9: A programmable RNA editing tool

Posted: 03 Oct 2014 06:43 PM PDT

A powerful scientific tool for editing the DNA instructions in a genome can now also be applied to RNA as researchers have demonstrated a means by which the CRISPR/Cas9 protein complex can be programmed to recognize and cleave RNA at sequence-specific target sites.

Neurobiological basis of human-pet relationship: Mothers' brains respond differently to images of their child and their dog

Posted: 03 Oct 2014 06:43 PM PDT

How closely does the relationship between people and their non-human companions mirror the parent-child relationship? Researchers makes a contribution to answering this complex question by investigating differences in how important brain structures are activated when women view images of their children and of their own dogs.

New educational modules harness power of e-learning for pancreatic cancer education

Posted: 03 Oct 2014 10:53 AM PDT

How can healthcare professionals stay on top of the ever-evolving field of pancreatic cancer? The ePOSSOM (ecancer POst Graduate School of Surgery Surgical Oncology Modules) project has launched a series of innovative educational modules to meet the educational needs of post-graduate surgical trainees looking to extend their knowledge on pancreatic cancer.

Fish colon offers insight into evolution

Skates have primitive colons. This may not sound like a big deal, but it is. The discovery could change scientific understanding of evolution, of how animals emerged from water to live on land.

Help explain 'chemo brain' through snail research

Posted: 03 Oct 2014 06:20 AM PDT

It is estimated that as many as half of patients taking cancer drugs experience a decrease in mental sharpness. While there have been many theories, what causes "chemo brain" has eluded scientists.

Big-headed ants grow bigger when faced with fierce competitors

Posted: 02 Oct 2014 11:18 AM PDT

The big-headed ant (Pheidole megacephala) is considered one of the world's worst invasive ant species. As the name implies, its colonies include soldier ants with disproportionately large heads. Their giant, muscle-bound noggins power their biting parts, the mandibles, which they use to attack other ants and cut up prey. In a new study, researchers report that big-headed ant colonies produce larger soldiers when they encounter other ants that know how to fight back.

Diet affects mix of intestinal bacteria, risk of inflammatory bone disease

Posted: 02 Oct 2014 09:32 AM PDT

Diet-induced changes in the gut's bacterial ecosystem can alter susceptibility to an autoinflammatory bone disease by modifying the immune response, scientists have reported. The research provides insight into how the thousands of bacteria and other microorganisms that live in the intestines affect health.

Ancient protein-making enzyme moonlights as DNA protector

Posted: 02 Oct 2014 09:30 AM PDT

An enzyme best known for its fundamental role in building proteins has a second major function -- to protect DNA during times of cellular stress -- has been found by scientists. The finding, remarkable on a basic science level, also points the way to possible therapeutic applications.

Beer from 1840 shipwreck: Scientists developing new taste sensations for beer lovers from old beer

Posted: 02 Oct 2014 06:24 AM PDT

Scientists are analyzing the bottles of beer salvaged from the 1840s shipwreck found near the Ă…land Islands in 2010. Living bacteria found in the bottles were subject to further tests to find out how the cells had survived for so long in the wreck.
