Health Research: Link between intelligence and longevity is mostly genetic ♦ Pygmies show growth plasticity is key to human evolution ♦ Lead poisoning risk from recycling older electronic equipment

Link between intelligence and longevity is mostly genetic The tendency of more intelligent people to live longer has been shown, for the first time, to be mainly down to their genes.
Firms 'underinvest' in long-term cancer research Pharmaceutical firms 'underinvest' in long-term research to develop new cancer-fighting drugs due to the greater time and cost required to conduct such research.
Pygmies show growth plasticity is key to human evolution While the stature of pygmies is well-suited to tropical rainforests, the mechanisms underlying their growth remain poorly understood. In order to decipher these mechanisms, a team of scientists studied a group of Baka pygmies in Cameroon. Their findings revealed that their growth rate differed completely from that of another pygmy cluster, despite a similar adult height, which implies that small stature appeared independently in the two clusters.
Doctor warns about lead poisoning risk from recycling older electronic equipment The disposal and recycling of electronic devices has increased exposure to lead and other toxicants and created 'an emerging health concern,' according to a pediatrician who has expertise in the area.
Early evidence suggests hybrid cochlear implants may benefit millions with common form of hearing loss People with a common form of hearing loss not helped by hearing aids achieved significant and sometimes profound improvements in their hearing and understanding of speech with hybrid cochlear implant devices.
