The famous ocean explorer, Sylvia Earle, has long advocated that people stop eating fish. Recently, George Monbiot made a similar plea in The Guardian – there’s only one way to save the life in our oceans, stop eating fish – which, incidentally, would condemn several million people to starvation. In both cases, it’s facile reasoning. The oceans may suffer from […]
Predicting the future is the pinnacle of what science can do. It’s impressive enough for a scientist to look at existing data and compose a theory explaining it. It’s even more impressive for a scientist to predict what data will look like before they are collected. The periodic table is central to chemistry precisely because […]
Back in 1995, then World Bank Vice President Ismail Serageldin made an important prediction about the future: “The wars of the next century will be fought over water.” Thankfully, No wars have been fought strictly over water in modern history. In fact globally the number of international agreements over water far exceeds the number of international conflicts. That paradox shows that water can be just as powerful a driver of cooperation as of conflict between nations, regions, and communities. But that doesn’t mean Serageldin is wrong.
The confirmation of Einstein’s new general theory of relativity on the 29th of May 1919 made headlines around the world. Arthur Stanley Eddington’s measurement of the gravitational deflection of starlight by the Sun was a triumph of experimental and theoretical physics.
For millennia, mankind has understood that we can apply heat to raw food materials to make them safe to consume and keep their quality for longer. Cooking is even credited as being key to human evolution, as its discovery (a trick unique to humans) greatly reduced the amount of energy bodies needed to digest and extract nutrients from food, allowing saved energy to be diverted into useful pathways such as those which developed more sophisticated brains.
Sun exposure is the primary risk factor for skin cancer: increased exposure due to ozone depletion is expected to lead to increases in the incidence of skin cancers, including melanoma. Sun exposure in childhood is predictive of skin cancer later in life.
Human impact on climate and environment is a topic of many discussions and research. While the social, economic, and environmental effects of climate change are important, climate change could also increase the spread of infectious diseases dramatically. Many infectious agents affect humans and animals. Shifts of their habitats or health as a result of climate change and […]
The year 2019 is the 150th anniversary of the publication of Russian chemist Dmitri Mendeleev’s Periodic Table. The Periodic Table is a tabular arrangement of all elements. Mendeleev developed it to recognize patterns of the known elements. He also predicted that later scientists would fill in new elements in the gaps of his table. Today’s […]
On March 3, 1912, Henrietta Swan Leavitt made a short contribution to the Harvard College Observatory Circular. With it she laid the foundations of modern Astronomy. Locked in solitude due to her deafness, Leavitt was the first person to discover how to measure distance to galaxies, thus expanding our understanding of the Universe in one giant leap.
Americans spend more money on health than anyone else in the world, yet they live shorter, less healthy lives than citizens of other rich countries. The complex reason for this is the multiple factors that affect our health. The simple reason is the fact that people seldom talk about these factors. Here are five things […]
The amount of carbon dioxide released into the atmosphere by burning of fossil fuels is at a staggering all time high of 34 billion tonnes, having risen every decade since the 1960s.
Gender inequality persists in all sectors of society, including science and medicine disciplines. While female clinicians and researchers are increasing in number and now comprise almost 50% of medical school graduates in the United States, they remain underrepresented in scholarly publications and academic positions (20% to 49% of researchers in 12 countries and regions). Although nearly half of medical […]
According to his friend and biographer Ernest Jones Sigmund Freud was fond regaling him with “strange or uncanny experiences with patients.” Freud had a “particular relish” for such stories. 2019 marks the centenary of the publication of Freud’s essay, “The ‘Uncanny.’” Although much has been written on the essay during that time, Freud’s concept of the uncanny is often not well understood.
In 2019, the Cambridge Philosophical Society celebrates its 200th anniversary. When it was set up in 1819, Cambridge was not a place to do any kind of serious science. There were a few professors in scientific subjects but almost no proper laboratories or facilities. Students rarely attended lectures, and degrees were not awarded in the […]
The global economy for products composed of biological materials is likely to grow 3.6% between now and 2025. This in response to serious environmental challenges the world will face. Such products have enormous potential to provide solutions to global challenges like food security, energy production, human health, and waste reduction. This economic growth may strongly […]
Our Planet, Netflix’s new nature documentary voiced by David Attenborough, arrives on the online streaming platform today. The series explores the wonders of the natural world, focusing on iconic species and stunning wildlife spectacles.
