Gut microbiome regulates the intestinal immune system
A new study in mice unveils the role of vitamin A in immune system regulation, a finding that could assist in developing treatments for autoimmune and inflammatory diseases as well as vitamin A deficiency.

How much are we learning about the genome? Natural selection is science's best critic
Even as they've struggled to highlight parts of the human genome worth investigating, scientists have wondered how much they're actually learning through the methods they use. Now, two researchers have determined that natural selection and our own evolutionary history might be science's best critics, and guides for future research.

Mysteries of the primrose unraveled
Plant scientists have succeeded in unraveling the complete genome sequence of the common primrose -- the plant whose reproductive biology captivated the Victorian naturalist Charles Darwin. The research team has identified, for the first time, the landscape of genes which operate within the primrose's two different flowering forms that are involved in the reproductive process. This adds fresh insight to a puzzle that scientists have been grappling with for over 150 years.

Plants don't like touch: Green thumb myth dispelled
Research has found that plants are extremely sensitive to touch and that repeated touching can significantly retard growth. The findings could lead to new approaches to optimizing plant growth and productivity -- from field-based farming to intensive horticulture production.

Protein police keep the immune system in check
Researchers learn how a key transcription factor helps regulate the immune system and could be critical to understanding autoimmune disease and cancer immunosuppression.

The gene helping submerged plants
Climate change threatens plants as the risks of flooding increase. A new study shows that special genes are key to keeping plants from withering, remaining healthy and resistant to a lack of oxygen when they are underwater for a period of long time. Developing tolerant plant varieties that have this gene will increase harvest and will be increasingly important as the changing climate leads to more rainfall.

New RNA sequencing strategy provides insight into microbiomes
Scientists have demonstrated the application of high-throughput transfer RNA sequencing to gut microbiome samples from mice that were fed either a low-fat or high-fat diet.

Protein involved in nematode stress response identified
When humans experience stress, their inner turmoil may not be apparent to an outside observer. But many animals deal with stressful circumstances -- overcrowded conditions, not enough food -- by completely remodeling their bodies. These stress-induced forms, whether they offer a protective covering or more camouflaged coloration, can better withstand the challenge and help the animal survive until conditions improve.
