Discovery reveals how plants make cellulose for strength and growth
(University of Virginia Health System) The discovery unveils the molecular machinery that plants use to weave cellulose chains into cable-like structures called ‘microfibrils.’
How bacteria build essential carbon-fixing machinery
Scientists have revealed new insight into how cyanobacteria construct the organelles that are essential for their ability to photosynthesise.
Agriculture – a climate villain? Maybe not!
The UN’s Intergovernmental Panel on Climate Change (IPCC) claims that agriculture is one of the main sources of greenhouse gases, and is thus by many observers considered as a climate villain.
Sledge dogs are closely related to 9,500-year-old ‘ancient dog’
(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.
Hummingbirds see colors we can only imagine
“Our experiments enabled us to get a sneak peek into what the world looks like to a hummingbird,” one scientist said.
Using tiny electrodes to measure electrical activity in bacteria
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 for the sequestration of neurotransmitter drugs in water
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.
Dance of 3 stars confirms Einsteinâs âmost fortunate thoughtâ
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.
Honeybee lives shortened after exposure to two widely used pesticides
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.
Living With Global Warming – CounterPunch.org – CounterPunch
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…
