(ANSA) – ROMA, 4 APR – Durante l’ultima campagna di scavi nel bacino sedimentario di Buya, in Eritrea, l’equipe internazionale guidata dal paleoantropologo della Sapienza Alfredo Coppa ha rinvenuto nuovi reperti umani e dell’industria litica risalenti a circa un milione di anni fa.
I ricercatori hanno parlato subito di un ‘‘santuario delle amigdale”, poiche’ il sito e’ senz’altro uno dei posti a piu’ alta concentrazione di manufatti litici di tipo acheuleano risalente a quel periodo

- Outlook is grim for mammals and birds as human population growsThe ongoing global growth in the human population will inevitably crowd out mammals and birds and has the potential to threaten hundreds of species with extinction within 40 years, new research shows. […]
- Researchers discover immunity mechanism: Platelets patrolling the bloodstreamScientists have discovered a mechanism that is used to protect the body from harmful bacteria. Platelets, a component of blood typically associated with clotting, were discovered to actively search for specific bacteria, and upon detection, seal it off from the rest of the body. The findings provide the science community with a greater understanding of immun […]
- Older males make better fathers says new research on beetlesResearchers have found that older male burying beetles make better fathers than their younger counterparts. The study found that mature males, who had little chance of reproducing again, invested more effort in both mating and in parental care than younger males. […]
- City slicker or country bumpkin: City-life changes blackbird personalitiesThe origins of a young animal might have a significant impact on its behavior later on in life. Researchers have been able to demonstrate in hand-reared blackbirds that urban-born individuals are less curious and more cautious about new objects than their country counterparts. This study sheds light on an interesting debate on whether personality differences […]
- Contribution of particulate matter from air pollution to forest declineAir pollution is related to forest decline and also appears to attack the protecting wax on tree leaves and needles. Scientists have now discovered a responsible mechanism: particulate matter salt compounds that become deliquescent because of humidity and form a wick-like structure that removes water from leaves and promotes dehydration.
