How plants measure their carbon dioxide uptake
When water is scarce, plants can close their pores to prevent losing too much water. This allows them to survive even longer periods of drought, but with the majority of pores closed, carbon dioxide uptake is also limited, which impairs…
The secret of fireworm is out: molecular basis of its light emission
«This work is an important milestone in the framework of a large project, aimed at full characterization of a novel bioluminescent system, including the luciferase enzyme, luciferin substrate, key reaction products, the mechanism of light-emission, and biosynthetic pathways for luciferin…
Metal particles abraded from tattooing needles travel inside the body
Allergic reactions are common side effects of tattoos and pigments have been blamed for this. Now researchers prove, for the first time, that particles wear from the needle during the tattooing process and contain the allergens nickel and chromium and…
Scientists have found longevity biomarkers
An international group of scientists studied the effects of 17 different lifespan-extending interventions on gene activity in mice and discovered genetic biomarkers of longevity. The results of their study were published in the journal Cell Metabolism . Nowadays, dozens of…
Breath! Respiring microbes generate more energy
Researchers have now shed light on how bacteria and baker’s yeast generate and use their energy to g
Evolution designed by parasites
While analyzing interactions between parasites and hosts, a substantial amount of research has been devoted to studying the methods parasitic organisms use to control host behavior. In “Invisible Designers: Brain Evolution Through the Lens of Parasite Manipulation,” published in the…
Immune cells drive gallstone formation
Sticky meshworks of DNA and proteins extruded by white blood cells called neutrophils act as the glue that binds together calcium and cholesterol crystals during gallstone formation, researchers in Germany report August 15 in the journal Immunity . Both genetic…
Dartmouth receives $12.5 million grant to establish Center for Quantitative Biology
Dartmouth’s Geisel School of Medicine has been awarded a 5-year, $12.5 million grant from the National Institutes of Health (NIH) to establish a Center for Quantitative Biology (CQB) that will bring together and enhance initiatives in computational biology, bioinformatics, and…
Green chemists find a way to turn cashew nut shells into sunscreen
Team is working on techniques to produce useful compounds from wood and other fast growing non-edibl
Genetic redundancy aids competition among bacteria in symbiosis with squid
The molecular mechanism used by many bacteria to kill neighboring cells has redundancy built into its genetic makeup, which could allow for the mechanism to be expressed in different environments. Some strains of luminescent bacteria that compete to colonize the…
‘Catcher of the rye’ method detects rye gluten proteins in foods
Gluten-free diets have been trendy for several years now, with adherents claiming that avoiding grains that contain the substance helps with weight loss or improves general health. However, for people with celiac disease, avoiding gluten is not a fad but…
ASU researchers use new tools of data science to capture single molecules in action
In high school chemistry, we all learned about chemical reactions. But what brings two reacting molecules together? As explained to us by Einstein, it is the random motion of inert molecules driven by the bombardment of solvent molecules. If brought…
New drug targets early instigator of Alzheimer’s disease
Over a hundred years after they were first identified, two ominous signposts of Alzheimer’s disease (AD) remain central topics of research–both formed by sticky accumulations of protein in the brain. Amyloid beta solidifies into senile plaques, which congregate in the…
