Climate change explained through Tetris

“There’s a game of Tetris happening on a global scale: The playing space is planet Earth, and all those pesky, stacking blocks represent carbon dioxide — a greenhouse gas that is piling up ever more rapidly as we burn the fossil fuels that run our cars, factories and power plants. Joss Fong outlines how this overload of CO2 leads to climate change and reminds us that, unlike Tetris, we won’t get an opportunity to start over and try again.”

Cancer risk: Chance or Choice?

CHANCE OR CHOICE
Does cancer play dice with us?

In 2015, Tomasetti and Vogelstein published in Science a famous and controversial paper on cancer etiology1. They showed that lifetime risk of many different cancers highly correlates with the total number of stem cell divisions of the tissue from where the cancer arises. The correlation between these two parameters was R=0.81.To understand how strong this correlation is, one can imagine that R of value 1 would mean a perfect correlation: one could exactly calculate the value of one parameter just knowing the value of the other. Tomasetti and Vogelstein interpreted these data as a proof of the existence of another player in cancer etiology, along with hereditary and environmental components: intrinsic replication errors.

In recent years, a real revolution is ongoing in the molecular biology field. This revolution roots back to the 60’ and 70’ years of last century, when all the scientists around the world began to daydream about the possibility of curing diseases by manipulating the human genome taking advantage of the rising methodologies of recombinant DNA. Sometimes dreams come true and, nowadays, genomic manipulation is reality thanks to a newly discovered technique that allows us to specifically and accurately modify our DNA.

In the second chapter of the “Hallmarks of cancer” series we talk about the cancer cell capability to continuously sustain proliferative signalling.

As discussed in the first chapter (see here), Continue reading “Cancer Series: Sustaining Proliferative Signalling”

The future of drug testing is today!

Nowadays, poor ability of the animal models to resemble human biology represents one of the major medical research drawbacks. According to a Tufts University study, the overall cost to develop a new pharmaceutical drug exceeds 2.5 billion dollars1. Continue reading “The future of drug testing is today!”

The Science behind earthquakes

The earthquake that struck centre Italy few days ago reminded us, once again, of Nature’s power. Nevertheless, it also firmly reminds us that human beings have the possibility to limit the damages caused by natural disaster. Continue reading “The Science behind earthquakes”
