Crohn"s disease patients have specific IgG antibodies to human bacterial flagellins
Last year, researchers used a mouse model that included immune-reactive T cells from patients with Crohn's disease in a proof-of-principle demonstration that a flagellin-directed immunotherapy might provide similar benefits in patients. Now they have.....»»
Lanthanide nanohybrids show promise in treating pulmonary biofilm infections
Bacterial biofilm infections are among the leading causes of morbidity and mortality among patients with cystic fibrosis or those with weakened immune systems. Treatment for biofilm infections usually entails intensive antibiotic therapy. There is an.....»»
Researchers reprogram bacterial gene activity with red light
Researchers at the University of Bayreuth have changed the sensitivity of bacterial systems for controlling gene activity to red light and reprogrammed their molecular response to the light stimulus. The results, published in Nature Communications, o.....»»

The global orange juice crisis is caused by disease and bad weather: How to keep it on the breakfast table
Just as the world is coming out of the tea crisis, another breakfast staple, orange juice, is in the spotlight. Supply constraints have led to prices shooting up by more than 20% in a year......»»
Researchers demonstrate new way to "squeeze" infrared light
Researchers have for the first time demonstrated that a specific class of oxide membranes can confine, or "squeeze," infrared light—a finding that holds promise for next generation infrared imaging technologies. The thin-film membranes confine infr.....»»
Lung organoids reveal how pathogens infect human lung tissue
How do pathogens invade the lungs? Using human lung microtissues, a team at the Biozentrum of the University of Basel has uncovered the strategy used by a dangerous pathogen. The bacterium targets specific lung cells and has developed a sophisticated.....»»
Siberia"s "mammoth graveyard" reveals 800-year human interactions with woolly beasts
Woolly mammoths are evocative of a bygone era, when Earth was gripped within an Ice Age. Current knowledge places early mammoth ancestors in the Pliocene (2.58–5.33 million years ago, Ma) before their populations expanded in the Pleistocene (2.58 M.....»»
Protein study could help researchers develop new antibiotics
A bacterial enzyme called histidine kinase is a promising target for new classes of antibiotics. However, it has been difficult to develop drugs that target this enzyme, because it is a "hydrophobic" protein that loses its structure once removed from.....»»
Improved prime editing system makes gene-sized edits in human cells at therapeutic levels
Scientists at the Broad Institute of MIT and Harvard have improved a gene-editing technology that is now capable of inserting or substituting entire genes in the genome in human cells efficiently enough to be potentially useful for therapeutic applic.....»»
Astrophysicists calculate the likelihood that Earth was exposed to cold harsh interstellar clouds 2 million years ago
Around two million years ago, Earth was a very different place, with our early human ancestors living alongside saber-toothed tigers, mastodons, and enormous rodents. And, depending on where they were, they may have been cold: Earth had fallen into a.....»»
Scientists have traced the origin of the modern horse to a lineage that emerged 4,200 years ago
