Neurochemistry of power

The neurochemistry of power has implications for political change By Nayef Al-Rodhan, University of Oxford Power, especially absolute and unchecked power, is intoxicating. Its effects occur at the cellular and neurochemical level. They are manifested behaviourally in a variety of ways, ranging from heightened cognitive functions to lack of inhibition, poor judgement, extreme narcissism, perverted behaviour, and gruesome cruelty. The primary neurochemical involved in the … Continue reading Neurochemistry of power

Antimicrobial action of bleach

In my AS level chemistry class, students study the disproportionation reaction of chlorine with alkali. In this reaction chlorine gets oxidized and reduced. While studying this topic one of the students asked how chlorine actually kills microbes. This news article published by the British journal Nature in 2008 responds to his question: …Now, researchers have found that bleach can kill bacteria by attacking proteins, quickly destroying … Continue reading Antimicrobial action of bleach

Table salt under pressure

Everything around you is made of elements that scientists have studied in quite some detail over the last 200 years. But all that understanding breaks down when these elements are subjected to high pressure and temperature. Now, using an advanced theoretical understanding and extreme conditions, researchers have converted table salt into exotic chemicals. Salt is made from one part sodium (Na) and one part chlorine … Continue reading Table salt under pressure

The life and times of a pharmaceutical drug

One of the chapters in the A level (final year of high school) Salters Chemistry in the UK was drug discovery and clinical trials. The story line book covered this topic in 5 or so pages. What was not mentioned were the actual difficulties and the hurdles that the scientists underwent to discover a new drug. This article published in ‘The New Yorker‘ takes us … Continue reading The life and times of a pharmaceutical drug

CO2 level in the atmosphere

  For the first time in human history, the concentration of climate-warming carbon dioxide in the atmosphere has passed the milestone level of 400 parts per million (ppm). The last time so much greenhouse gas was in the air was several million years ago, when the Arctic was ice-free, savannah spread across the Sahara desert and sea level was up to 40 metres higher than today. Read more…   … Continue reading CO2 level in the atmosphere

Politics & Science

What happens to people when they become government science advisers? Are their children taken hostage? Is a dossier of compromising photographs kept, ready to send to the Sun if they step out of line? I ask because, in too many cases, they soon begin to sound less like scientists than industrial lobbyists. The mad cow crisis 20 years ago was exacerbated by the failure of … Continue reading Politics & Science

Pollution and Cooling effect

Clouds profoundly influence weather and climate. The brightness2 and lifetime of clouds is determined by cloud droplet number concentration, in turn dictated by the number of available seed particles. The formation of cloud droplets on non-volatile atmospheric particles is well understood. However, fine particulate matter in the atmosphere ranges widely in volatility. Co-condensation of semi-volatile compounds with water increases a particle’s propensity for cloud droplet formation, with … Continue reading Pollution and Cooling effect

Metabolomics

Compounds present in exhaled breath can act as a “fingerprint” for individuals, scientists say. These “metabolites” represent the waste products of the body’s chemistry – but their uniqueness had never been shown. Read more on BBC’s website *** Abstract: “The metabolic phenotype varies widely due to external factors such as diet and gut microbiome composition, among others. Despite these temporal fluctuations, urine metabolite profiling studies … Continue reading Metabolomics

How to Write a Paper to Communicate your Research

When should you begin to think about writing up your research for publication? How do your students handle your approach of writing while you research? How do new technologies help scientists communicate their work? How many drafts does each paper undergo? Do you have your papers undergo an internal review? Do authors need to be thinking of marketing their articles? How concerned should I be … Continue reading How to Write a Paper to Communicate your Research
