Researchers sequenced and analyzed over 1.8 million genetic codes to determine functions of genes involved in polysaccharide capsule production. The new vaccine protects children from many common serotypes, but monitoring is needed to track potential changes in capsular types.
A light-based device probe has been developed to detect early cancer signs in the esophagus, emitting light that scatters when it hits the cell nucleus. The technology could be adapted to detect pre-cancerous cells on any organ's surface, potentially increasing the likelihood of cancer detection.
The Bering Sea ecosystem is responding to changes in Arctic climate, with shifts in species and ecosystem structure impacting native communities. The region's productivity and carbon balance are being altered, with potential implications for the role of the sea as a carbon sink.
Researchers found that inhibiting CPT1A in rats improved insulin sensitivity and reduced blood sugar levels, suggesting a critical role for this enzyme in nutrient sensing. The study provides new insights into the molecular mechanisms underlying diet-induced obesity and insulin resistance.
Robert Downs is almost halfway to creating a library of spectral fingerprints for all the Earth's minerals, with over 1,500 cataloged so far. The associate professor of geosciences is collaborating with colleagues to develop a pocket-sized Raman spectrometer for use on Mars and handheld instruments for identifying gemstones on Earth.
Researchers at Yale are expanding a study using magnetic stimulation to treat schizophrenia, including a new trial with 90 patients. The treatment involves TMS, which modestly reduces the capacity of neurons to activate each other and may curb hallucinations.
Researchers at Joslin Diabetes Center discovered a link between Necdin and E2F4 proteins, altered after patients took the drug rosiglitazone. The study suggests that thiazolidinediones work by altering cell differentiation states, offering new potential targets for diabetes treatment.
Research suggests that high fluoride intake from beverages during infancy and early childhood increases the risk of dental fluorosis in permanent incisors. Consuming more 100% juice and infant formulas with naturally high water fluoride concentrations also contribute to increased fluoride intakes.
Researchers identified a transcription factor gene called spineless as the key regulator for establishing the retinal mosaic in fruit flies. In this study, the researchers found that receptor cells made their 'decision' autonomously without the influence of nearby cells.
Scientists find gene regulation plays a key role in human-chimp differences, with rapid changes occurring in transcription factors over 5 million years. These changes may be linked to dietary shifts and cooking habits, enabling humans to thrive in new environments.
