Dormice, sea urchins and fresh figs were among the delicacies enjoyed by ordinary Romans, British archaeologists have revealed after discovering a giant septic tank at one of the ancient cities destroyed by the eruption of Mt Vesuvius...
Archaeologists found a treasure trove of everyday artefacts after digging up nearly 800 sacks of compacted human waste from the tank, which lies beneath the remains of a Roman apartment block in Herculaneum, destroyed after it was buried by ash from the volcano in AD79.
The British team has found hundreds of objects, including bronze coins, precious stones, bone hair pins and an exquisite gold ring decorated with a tiny figure of the god Mercury.
Close scrutiny of the composted human waste has revealed that the estimated 150 middle- and lower-class inhabitants of the three-storey block of flats had a much more varied diet than previously thought.
They regularly feasted on fish, spiky sea urchins, figs, walnuts, eggs and olives, using the olive pips as fuel in their homes.

Garum was a popular fish sauce condiment. It was made by the crushing and fermentation in brine of the intestines of fish such as tuna, eel, anchovies, and mackerel. Because the production of garum created such an unpleasant smell, its fermentation was relegated to the outskirts of cities. The finished product was quite mild and subtle, and was mixed with wine, vinegar, pepper, oil, or water to enhance the flavor of many dishes. Garum is similar to fish sauce used today in Thai and Vietnamese cooking.
The preparation of Worcestershire sauce is reportedly a foul thing as well... But I couldn’t imagine life without it. :-)
Edible dormice: The older they get the more they rejuvenate their cells
The shortening of telomeres in cells was thought to be an important biomarker for lifespan and aging. The edible dormouse (Glis glis), a small hibernating rodent, now turns everything upside down. In contrast to humans and other animals, telomere length in the edible dormouse significantly increases in the second half of its life, as researchers from Vetmeduni Vienna found out just recently. The study was published in Scientific Reports.
"As far as I know, no previous study has reported such an effect of age on telomere lengthening," says Franz Hoelzl, one of the authors. Apparently, this unique pattern is due to the peculiar life history of this species. They can reach maximum lifespan of 13 years, which is a Methuselah-like age for a small rodent. "This extreme lifespan is almost certainly related to their ability to rejuvenate telomeres", says Hoelzl.
Telomeres are the endcaps of chromosomes, which prevent, together with proteins, the degradation of coding DNA sequences.
Telomeres in small animals shorten fast, but in edible dormice they even grow
In normal somatic cells, telomeres are shortened with every cell division. Besides, oxidative stress has a strong effect on telomere erosion. However, the rate of telomere shortening differs between species. For instance, it has been shown before that telomeres in fast-aging, short-lived wild animals erode more rapidly than in slow-aging, long-lived species.
Earlier this year, the author Franz Hoelzl and his colleagues from Vetmeduni Vienna showed that edible dormice has the capability to re-elongated its telomeres, given that food availability is high. This finding raised the question about the long-term balance between telomere attrition and repair.
The relative telomere length (RTL) gave evidence
To find an answer, the team started a long-tem study on changes in telomere length. In the Vienna Woods in Austria they regularly checked 130 nest-boxes that are occupied by free-living dormice. The researchers collected the rodent's buccal mucosa for three years. Thus, they could extract the DNA and determine the relative telomere length for each dormouse individually using qPCR. With this method scientists can define the amount of target DNA compared to a reference gene of the same sample.
Elongation does not only occur, it even increases in older edible dormice
"We found out that the telomeres were shortened in young animals but length significantly increased once the dormice were six years old or older. To top it all, the rate of telomere elongation also increased with increasing age of the dormice", says Franz Hoelzl.
Among the variables tested, only age significantly affected RTL in a non-linear pattern with telomere length decreasing in younger and increasing in older dormice. Hoelz says,
"Telomere length was not affected by time of the year, sex, body mass or reproductive activity at the time of sampling."
Nevertheless, the analysis of long term reproduction-data of the same population shows that the probability to reproduce also increases with age. This finding could indicate that telomere elongation is actually part of the preparation for upcoming reproductive events, as gestation and lactation could increase oxidative stress and the animals may attempt to protect their genome.....
Not too sure killin’ ‘em to eat ‘em would have left the Romans with enough empirical data. ;^)
