Around the world, vaccines are in retreat, shunned by populations who, for the most part, have never been exposed to the diseases that blighted or shortened the lives of their grandparents’ generation. But with the possible exception of quinine – for centuries the only treatment for malaria – and antibiotics, vaccines have saved more lives […]
Scientists working on the frontiers of medicine fear the uproar over the reported births of gene-edited babies in China could jeopardize promising research into how to alter heredity to fend off a variety of disorders. Researchers are rapidly learning how to edit DNA to fight such conditions as Huntington’s, Tay-Sachs and hereditary heart disease, conducting […]

(A 1998 policy simply "encouraged" parents to use "methods other than spanking.") However, the AAP is now taking a tougher stance against the so-called disciplinary tool. According to new guidelines released on the AAP News & […]
For decades, consensus among psychologists has held that a cluster of five personality traits—or a slight variation thereof—universally defines the structure of human personality.Previous research conducted in high-income countries and across many cultures found strong support for what experts refer to as the “Big Five”—openness, conscientiousness, agreeableness, extraversion and neuroticism.
