Photosynthesis, pigment–protein complexes and electronic energy transport: simple models for complicated processes

Posted on 18. December, 2017.

Essentially all the accessible energy for life in the Earth’s biosphere is made available through the process of photosynthesis, the conversion of light energy from the Sun into storable chemical energy for metabolism. The process itself has been the subject of remarkable evolution throughout Earth’s history.

Advances in antihydrogen physics

Posted on 30. March, 2015.

Antimatter has long held a grip on the fascination of both scientists and the general public, though usually for very different reasons. Dirac’s famous 1931 prediction of the existence of both the positron and the antiproton (though he did confess to know nothing of the nature of the proton) holds a special place in physics.

“Vibrational bonding”: a new type of chemical bond is discovered

Posted on 12. March, 2015.

Chemical bonding is the attractive force between atoms that causes them to form into aggregates such as molecules or solids. At its foundation, a chemical bond is always a result of the summed attractive and repulsive electrostatic interactions between a number of positively charged nuclei and a number of negatively charged electrons, but a hierarchy of different bond types of varying strength can be identified.

Free from the Science Reviews archives - Superconductivity

Posted on 9. March, 2015.

Superconductivity is one of the most explicit and dramatic forms of electronic order. We are baffled by its consequences, for example the complete breakdown of electrical resistance, the expulsion of small magnetic fields, the Josephson effect and magnetic levitation. But at a more conceptual level, the processes underlying these phenomena are equally captivating: why does a superconductor superconduct?

The transition from iron starvation to iron sufficiency as an important step in the progression of infection

Posted on 4. March, 2015.

Iron is an essential micronutrient for microbial life. At the start of an infection the host environment will normally restrict available iron, and innate immune responses will aim to further reduce iron, thus inhibiting growth of potential pathogens.

Endophytes – the chemical synthesizers inside plants - A Free Review

Posted on 24. February, 2015.

Endophytes are microbial entities that live within living tissues of plants.
In most cases their relationship with the host plant is symbiotic and probably mutualistic. Many are capable of synthesizing bio-active compounds that can be used by the plant for defense against pathogenic fungi and bacteria. Some of these compounds have proven useful for novel drug discovery.

Designer life using synthetic biology

Posted on 21. February, 2015.

Look anywhere on land or in the oceans and you will find a multitude of living creatures – plants and animals of all shapes and sizes – roughly 8.7 million eukaryotic species, give or take a million or so.

Then look closer, because most life is invisible to the human eye. A light microscope will reveal the bacteria; an electron microscope, the viruses. These organisms are everywhere.

Unpaired electrons as probes of catalytic systems

Posted on 14. January, 2015.

In the December issue of Science Progress, an overview is provided of the importance of molecular species containing unpaired electrons in catalytic systems, as revealed using ESR spectroscopy. The review aims to demonstrate the considerable extent of scientific progress that has been made in this broad topic during the past few decades.
