Climate Change Threatens Commercial Fishers From Maine to North Carolina
Most fishing communities from North Carolina to Maine are projected to face declining fishing options unless they adapt to climate change by catching different species or fishing in different areas, according to a study in the journal Nature Climate Change.
Modified Enzyme Can Increase Second-Generation Ethanol Production
One of the main challenges of second-generation biofuel production is identifying enzymes produced by microorganisms for use in a “cocktail” of enzymes to catalyze biomass hydrolysis, in which the enzymes act together to break down the carbohydrates in sugarcane trash and bagasse, for example, and convert them into simple sugars for fermentation.
Antioxidant Puts up Fight, but Loses Battle Against Toxic Protein Linked to Alzheimer’s Disease
New research may explain why an antioxidant that protects the brain is also associated with deterioration in areas susceptible to Alzheimer’s disease.
Hubble Sets Sights on an Explosive Galaxy
When massive stars die at the end of their short lives, they light up the cosmos with bright, explosive bursts of light and material known as supernovae.
Bees Required to Create an Excellent Blueberry Crop
Getting an excellent rabbiteye blueberry harvest requires helpful pollinators—particularly native southeastern blueberry bees—although growers can bring in managed honey bees to do the job, according to Agricultural Research Service (ARS) scientists.
