The origin of Chili peppers

UNIVERSITY RESEARCH

CHILI PEPPERS

Chili peppers, as they are commonly known, belong to the genus Capsicum, a genus that represents a complex variety of wild and domesticated species [2] which origin has long been discussed. In spite it was a general believe that the genus Capsicum originated in America, little was known about how long ago were they used as culinary ingredients. One added difficulty to achieve that is the fact that little is left after eating chili peppers, as most of them dissolve and are digested completely.

Only by analyzing the remaining of ancient pottery it was possible to find out an approximate date. In a study named "Prehispanic Use of Chili Peppers in Chiapas" where samples obtained from different pottery samples where analysed, it is mentioned how scientists believed that Chili peppers were used as culinary ingredients in different ancient dishes as well as part of beverage preparations used for religious purposes, in festivals or in a daily culinary use [2]. Other studies on the subject have brought more light into what seems to be the oldest domesticated food source in America. Image: Chili peppers by Morguefile.

From fossil fuels to poplars

ECOLOGY & CONSERVATION

POPLAR

I can't believe how did we managed to survive so long depending on fossil fuels. Crude oil, petrol, has been our main source of energy since the industrial revolution and about 90% of our vehicles nowadays use it as main source of energy, however this won't last long, or at least not long enough.

Other sources are needed and governments are desperately looking for other ones, some as the wind energy are already playing a big role in this migration towards renewable energies. Some countries are already meeting a big percentage of their daily needs using a combination of wind and solar energies, but those ones alone won't be able to meet our current and future needs, others as bio-fuel are being investigated.

Within these new options, some as algae, have been identified as a potential source for the replacement of petrol. Within this line, a new source of energy, poplars, has also been identified recently researchers of Michigan State University as another possible option towards the creation of future bio-fuels.

Health benefits of vanilla

HEALTH BENEFITS

VANILLA PODS

Vanilla planifolia is an Orchid commercially cultivated for the production of natural vanilla flavor. The genus Vanilla belongs to the family Orchidaceae, which consists of more than 110 described species [2]. Orchids have been among us long before we thought, in fact ancient fossilized remains of a pollen-bearing bee as the first hint of orchids in the fossil record were found to be the first reference of their existance as Harvard University biologists recently discovered [16].

Their study suggest that orchids may have co-existed with dinosaurs some 76 to 84 million years ago, including groups of modern orchids as the genus Vanilla, that also evolved very early during the rise of the plant family [16], something that may remind us about others as Ginkgo biloba, a plant that belongs to a group of trees, the ginkgoales, with an existence on earth dated more than 200 million years ago. 

A lot has been said about Vanilla but in fact, the most important, the health benefits of vanilla, are so much and so important that it was due time to do it, let's see some of them. Image: Morguefile.

Moss back to life after 1,500 years

ECOLOGY & CONSERVATION

MOSS

The oldest carbon-14-dated seed that has grown into a viable plant was a Judean date palm seed that was about 2,000 years old when it was recovered from excavations at Herod the Great's palace on Masada in Israel. The Judean palm seed was was germinated in 2005 [1]. Amazing isn't it? Well, according to British Antarctic Survey and Reading University researchers not much, or at least that's what their findings have demonstrated recently showed.

The researchers have brought back to life, after over 1,500 years in the Antarctic ice, moss frozen in permafrost, soil at or below the freezing point of water 0 °C (32 °F) for two or more years [2], in this case over 1,500 years! Researchers didn't only brought moss back to life but also demonstrated that it was able to survive and continue to grow, as if it was just kept for a week or two, what demonstrates that this part of the ecosystem can survive century to millenniums, time scales only seen in bacteria so far.
