Animal experimentation is one of the greatest ethical dilemmas facing modern science. While animal research leads to life-saving treatments, to anti-vivisectionists (people who oppose the use of animals in scientific research) the practice is cruel and barbaric, regardless of its potential benefit to human health. But what are the issues with animal research, and what…
Obesity is clinically defined when someone’s Body Mass Index (BMI) exceeds 30. It is a metabolic disorder where by energy intake from food and drinks exceeds energy consumption from metabolism and physical activities. There are many health-related risks associated with obesity, especially for children. This includes increased susceptibility for type II diabetes, cardiovascular diseases, and…
The dark side of DNA testing One hundred and fifty years ago, in a laboratory in Germany, a young scientist named Friedrich Miescher identified an unusual new chemical while studying white blood cells. At first scientists assumed it was unimportant, but then they began to uncover its remarkable structure: a double helix held together like…
How accelerators sweeten up the Standard Model of Particle Physics “There is nothing new to be discovered in physics now. All that remains is more precise measurement”. This famous quote by Lord Kelvin in 1900 spoke of a perspective shattered almost immediately by a stream of significant discoveries, such as the discovery of the electron…
What happens when one size does not fit all? The first race-based combination prescription drug, Hydralazine-plus-nitrate is used in the treatment of congestive heart failure. Among African Americans, life expectancy of those with heart failure is increased using this combination drug, whereas white Americans respond less effectively to the drug. Another drug, Gefitinib, used in…
“Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should”. 25 years on, this quote from Jurassic Park by the great Jeff Goldblum rings truer than ever. While every great scientific advancement experiences some level of discussion and controversy, no field attracts more debate than that…
Most researchers’ response to the word ‘collaboration’ is overwhelmingly positive. Many of the most influential scientific breakthroughs that have gone on to shape today’s scientific landscape have been the product of collaborations: Gates and Allen, the Wright brothers, and Watson, Crick and Franklin, to name a few. The global value of collaboration can be seen…
The Bern town clock chimes: once, twice, three times. Yet another patent on clocks sits at the desk, this one claiming originality for sending time through telephone lines. It was the age when electromechanical devices were starting to be used to synchronise distant clocks. From the comfort of the patent office, a young Albert Einstein…
It’s not about the science. In 1983, a gene from Agrobacterium (a plant-infecting bacterium) was successfully inserted into a plant cell, marking a ‘coming-of-age’ moment for plant genetic engineering. The resulting possibilities seemed endless; pest-resistant, self-fertilising and nutritionally-fortified crop varieties. But relatively little of this technology has been implemented on a global scale. Casual viewers…
