NewsScientists’ chemical breakthrough sheds light on origins of life
Researchers have discovered a tiny RNA molecule that could explain how life on Earth began. The findings reveal the team has identified a remarkably small ribonucleic acid (RNA) molecule, named QT45, that can copy itself and its complementary strand.

NewsGut microbiome may be the link to gluten sensitivity without celiac disease
Researchers found that after antibiotic treatment, mice exposed to gluten had changes in the bacteria living in the gut. These shifts in bacteria types altered how they processed carbohydrates, fats and sugars which may influence how these nutrients are recognized by the immune system.

NewsImmunity against common virus leveraged against pancreatic cancer
Researchers have discovered a promising new treatment approach for pancreatic cancer. The approach leverages the body’s natural immune response to cytomegalovirus (CMV), a common but typically harmless virus that most people are infected with at some point in their lives.

NewsNewly discovered bacterium converts carbon dioxide into chemicals using electricity
A newly identified soil bacterium may help unlock cleaner ways to recycle carbon dioxide and produce valuable chemicals using electricity. The sulfate reducing bacterium Fundidesulfovibrio terrae possesses an unusual ability to both export and absorb electrical energy while converting carbon dioxide into acetate.

NewsBeneficial bacterium deployed to protect turfgrass from fungal foes
A novel strain of Bacillus subtilis helps a variety of plants resist soil‑borne diseases, retain moisture and develop stronger root‑to‑shoot growth. New findings on the effect of UD1022 on dollar spot disease suggests intriguing implications for manufacturing of biological treatments for the fungal disease.

NewsRich medieval Danes bought graves ‘closer to God’ despite leprosy stigma, archaeologists find
Researchers used gravesites to investigate social exclusion based on illness, by studying whether people with leprosy or tuberculosis were kept out of the higher-status areas. Unexpectedly, they found that people who were ill with stigmatized diseases were buried just as prominently as their peers.
