A carbohydrate commonly found attached to plant proteins is a food source for the bacteria in our gut, new research suggests.
Gut microbiomes help bears with very different diets reach the same size
A recent study of the gut microbiome of Alaskan brown bears (Ursus arctos) shows that the microbial life in bears' guts allows them to achieve comparable size and fat stores while eating widely different diets. The work sheds light on the role of the gut microbiome in supporting health in...
Sifting through cellular recycling centers
A new method allows scientists to determine all the molecules present in the lysosomes -- the cell's recycling centers -- of mice. This could bring new understanding and treatment of neurodegenerative disorders.
Ocean scientists measure sediment plume stirred up by deep-sea-mining vehicle
Scientists measured a sediment plume stirred up by a protoype of a deep-sea-mining vehicle to help gauge the impact of such vehicles if they are used to mine minerals like nickel and cobalt. The vehicle created a dense sediment plume that remained relatively low, staying within 2 meters of the...
Rising Sea Temperatures Threaten Atlantic Populations of Bulwer’s Petrels
The impact of the rise in sea temperatures predicted by the Intergovernmental Panel on Climate Change (IPCC) could affect the survival of the North Atlantic populations of Bulwer's petrel in the Azores, Canary Islands and Cape Verde, according to a study conducted by the Seabird Ecology Group of the Faculty...
Fertilisers Cause More Than 2% of Global Emissions
Unlike organic fertilisers, which come from plant or animal material, synthetic fertilisers are made by humans using chemical processes.
Mosquitoes that can’t spread malaria engineered by scientists
Scientists have engineered mosquitoes that slow the growth of malaria-causing parasites in their gut, preventing transmission of the disease to humans.
New Study Sheds Light on the Effect of Rain and Clouds on Atmospheric Aerosols
Wet processes in the atmosphere, such as clouds and precipitation, have a strong impact on the concentrations and chemical composition of atmospheric aerosols.
Why Do Woodpeckers Peck? New Discovery About Bird Brains Sheds Light on Intriguing Question
A team led by a Brown biologist discovered that the same specialized brain area that helps songbirds learn their songs also exists in woodpeckers, suggesting that the communicative drumming evolved in a similar way.
NASA’s InSight Hears Its First Meteoroid Impacts on Mars
The Mars lander’s seismometer picked up vibrations and sounds from four impacts in the past two years, a development detailed in a study co-authored by Brown planetary scientist Ingrid Daubar.
