When did the largest ocean current on Earth start?

...chemistry on these teeth, I can interpret whether Atlantic or Pacific waters (with distinct chemical signatures) were dominant in the water column. If the ACC started 50 million years ago, it may have been the cause of a major period of cooling. Study of the ACC during past climates allows us to better understand the potential change the current may face as the climate...

Nanotechnology: Good things come in small packages

...chemistry to engineering, physics and material sciences. Its application in medicine constitute an emerging field of research with great focus to be given on nanoparticles use for cancer treatment. Nanotechnology offers a vital tool for researchers in cancer detection, diagnosis, prevention and therapy. Statistics for this disease show that at least 1 in 2 people in UK...

How scientists found rare fireball meteorite pieces on a driveway – and what they could teach us

...chemistry that led to life on Earth. This can give an idea of how widespread that chemistry might be (or have been) in the Solar System - and even the universe. Searching for a meteorite in a small village and its surrounding fields is not usually hazardous and requires little in the way of risk assessment: ask permission of the owners to access their land, observe the...

Noble gases

...Chemistry qualification. Video Text version Here are five of the six noble gases: helium, neon, argon, kypton and xeon. They're all colourless and transparent. Krypton and xeon form compounds only with difficulty. Helium, neon and argon don't form compounds at all. As we descend the group in the periodic table the atomic number and relative atomic mass increases. The...

Systems explained: What do we mean by feedback?

...chemistry (adrenal hormones are produced, for example). Something then needs to be done to reduce stress and the production of adrenalin. Positive Feedback Positive feedback occurs when an increase in one thing leads to an increase in another and so on in a domino, vicious circle or spiral effect. In the boat example, when a person steering is distracted, and takes their...

How are Ethiopian coffee growers responding to climate change?

...chemistry at the University of Nairobi’s Institute for Climate Change Adaptation, Kenya, says that although the study cannot predict with full certainty, it holds important messages for policymakers. “Start planning to expand coffee growing areas to higher elevation, he suggests. “The expansion should be coupled with forestation of the areas.“ Researchers and...

Using lanthanides as medical imaging tools

...chemistry, I hadn’t heard much about them. Lanthanides, situated apart from the main chart of the periodic table and traditionally known as the “rare earth metals”, tend to be thought of as uncommon and strange elements. However, a bit of digging into their history shows that they are far from rare and are in fact, found abundantly in nature. For instance, neodymium...
