Malaria – La ricerca continua

La malaria, secondo i dati dell’Organizzazione Mondiale della Sanità, continua ad uccidere oltre mezzo milione di persone l’anno. La storia intrecciata millenaria tra l’evoluzione del P. falciparum e quella dell’uomo rivela come l’uomo e i parassiti della malaria abbiano una relazione basata su dinamiche genetiche; a turno, ognuno sviluppa mutazioni per avere la meglio sull’altro.

Sneaky Mutations in the Fight Against Malaria

Plasmodium falciparum — one of the parasites responsible for the transmission of malaria — is the umpteenth amazing example of how environmental constraints encourage adaptation for survival and of how inbreeding, by promoting lower genetic diversity, can cause a normally rare trait to become the norm. Recent scientific studies have shown that the continuous occurrence […]

Tropical Fever and Vital Breath

“There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are […]

Back to the Roots

DNA tests have nailed more than a few murderers, allowed the release of the wrongly imprisoned and forced celebrities to shell out big bucks to groupies with kids. Terms such as “genetic fingerprinting” and “barcoding” are also […]

E’ facile sentirsi minuscoli e spiazzati quando si arriva a Singapore, rimpiccioliti da altissimi grattacieli dalle forme più strane e persi negli infiniti corridoi commerciali sotterranei. Non sembra vero che le torri di uffici dalle luci cangianti, simili a imponenti ed enormi robot, distino poche fermate di metropolitana dalla densa foresta tropicale. A prima vista […]
