(University of Virginia Health System) The discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called ‘microfibrils.’
Scientists have revealed new insight into how cyanobacteria construct the organelles that are essential for their ability to photosynthesise.
(University of Copenhagen The Faculty of Health and Medical Sciences) Sledge dogs are much older and have adapted to Arctic conditions much earlier than previously thought. In a new study from the QIMMEQ project, researchers from the University of Copenhagen show that ancestors of modern sledge dogs have worked and lived with humans for over 9,500 years.
Scientists have developed an organic electrochemical transistor that they can use to measure and study in fine detail a phenomenon known as extracellular electron transfer in which bacteria release electrons.
Molecular containers that remove drugs, toxins, or malodorous substances from the environment are called sequestering agents. Scientists have developed a class of molecular containers that specifically sequester neurotransmitter antagonists. The barrel-shaped molecules called Pillar[n]MaxQ bind neuromuscular blocking chemicals 100,000-fold more tightly than established macrocyclic detoxification agents, the researchers report.
Researchers in Europe have now confirmed the universality of free fall – which Einstein called his most fortunate thought – with extremely high precision. To do it, they spent 8 years tracking a triple star system containing a millisecond pulsar.
The lives of honeybees are shortened — with evidence of physiological stress — when they are exposed to the suggested application rates of two commercially available and widely used pesticides.
I modeled mathematically the thermal imbalance of our biosphere, which we call global warming, so as to gain my own quantitative understanding of the interplay of the two major effects that give rise to this phenomenon. This is a “toy…
