Infant Immune Cells Not Functionally Immature as Previously Thought
A study has shown that putatively immature dendritic cells found in young children are able to induce robust immune responses. The results could lead to improved vaccination protocols.

New Genetic Disorder Discovered That Affects Brain and Craniofacial Skeleton
Researchers at the National Institutes of Health have discovered a new genetic disorder characterized by developmental delays and malformations of the brain, heart and facial features.

Treating Mice With Hormone Improves Physical Performance
A new study shows that humans express a powerful hormone during exercise and that treating mice with the hormone improves physical performance, capacity and fitness. Researchers say the findings present new possibilities for addressing age-related physical decline.

Antibiotic Resistance May Spread More Easily Than Anticipated
Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research shows that one reason could be significant genetic transfer between bacteria in our ecosystems and humans. This work has also led to new tools for resistance researchers.

Fatty Acid Could Help Combat Multiple Sclerosis
The abnormal immune system response that causes multiple sclerosis (MS) by attacking and damaging the central nervous system can be triggered by the lack of a specific fatty acid in fat tissue, according to a new Yale study.

Dormancy Key to "Tummy Bug" Bacteria's Success
Scientists have discovered how bacteria commonly responsible for seafood-related stomach upsets can go dormant and then "wake up".

New Insights Into Wound Healing Process
Biomedical engineers developed a technique to observe wound healing in real time, discovering a central role for cells known as fibroblasts. The work is the first demonstration of a wound closure model within human vascularized tissue in a petri dish.

How To Find Mutated Sperm? Just Go FISH
A new test quickly and easily identifies when sperm are carrying chromosomal mutations, and could be applied for men hoping to have children after chemotherapy and radiation treatments.

“Rewiring” at Non-Coding Genome Regions Important for Adaptation
Scientists shows that ‘genetic rewiring’ at non-coding regions - rather than mutations to protein-coding regions of genes - may play an important role in how cichlid fish are able to rapidly adapt to fill a staggeringly wide range of environmental niches in the East African Rift lakes.

Structure of Plants’ Energy Generators Revealed
Researchers have revealed the first atomic structures of the respiratory apparatus that plants use to generate energy. The 3D structures of these large protein assemblies – the first described for any plant species – are a step towards being able to develop improved herbicides that target plant respiration.
