One of the greatest mysteries that has enchanted scientists in recent times is how it was possible for chemical structures to become biological systems. Scientists have many theories regarding how chemistry eventually turned into biology, but no conclusive theories. A new study published in the journal Nature Chemistry may have succeeded in identifying a critical

Although most surface volcanism on the Earth is found at plate boundaries and is caused by shallow mantle processes, some surface volcanoes (e.g, Hawaii) occur far away from plate boundaries. It has been suggested that the formation of the intraplate volcanism is more related to processes in the deepest part of the Earth’s mantle. The
Slippery things, these carbon footprints can be. In principle, they are simple: the sum of all global warming emissions from cradle to grave of a given product. However, the wrinkle comes with multi-product processes – how is that footprint allocated between the various products coming out? And along the same lines, what exactly is a
The difference between an autotroph vs. heterotroph lies in the organism’s ability either produce its own food or need to ingest food. Autotrophs, such as plants, can produce their own food from light via photosynthesis or chemicals via chemosynthesis. Heterotrophs, such as humans, require ingesting food in order to produce energy and thus are not
The oceans have the capacity to slow down climate change by absorbing the atmospheric CO2 emitted by human activities. Australian scientists now question the role of oceanic eddies in absorbing atmospheric CO2. In the ocean, the absorption of CO2 is mainly carried by the phytoplankton, the microscopic plants that grow in the sunlit surface waters.
The continent of Africa has 54 countries in total according to the United Nations, including recognized states and territories. However, there are some disputed territories that could change the number of countries. Africa is the world’s second most populated and second largest continent. It is also home to a wide variety of countries. The exact
We wake up from a night’s sleep and go about our day until it becomes dark again and we head off to bed. That is the life of most humans and many mammals. We are diurnal because of this behavior. It is the behavior seen in many plants and animals because it is a convenient
Welcome to those who do not believe in climate change and wish to start a friendly debate over the internet! Better yet, welcome to those that do not fully understand the phenomenon of climate change and how human activity contributes to the occurrence – and are curious to learn more. And, best of all, welcome
We’re familiar with the role greenhouse gases play as the driving force behind climate change, through their absorption of longwave radiation and heating of the lower atmosphere. A lesser-known participant in radiative forcing is atmospheric aerosol. Because of their short lifetime that is on the order of a week, the aerosol impact on climate is
The life cycle of a butterfly includes a process called metamorphosis where each butterfly goes through 4 stages from an egg to a larva, then to a pupa, and finally, they turn into an adult butterfly. These 4 stages of a butterflies life varies slightly depending on the specific type of butterfly, as discussed below.
