Breaking up may actually not be hard to do, say scientists who’ve found a population of butterflies that may be on its way to a split into two distinct species.
Colonies of army ants, whose long columns and marauding habits are the stuff of natural-history legend, are usually antagonistic to each other, attacking soldiers from rival colonies in border disputes that keep the colonies separate. But new work by a researcher at the Harvard Museum of Comparative Zoology and colleagues at the University of Copenhagen shows that in some cases the colonies can be cooperative instead of combative.

Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species — a shrew and a lizard, giving each a venomous bite
Adult survivors of childhood cancer have an increased risk of suicidal thoughts, even decades after their cancer treatments have ended, according to a study led by Harvard researchers at Dana-Farber…
A team of Harvard and University of California, San Diego (UCSD), researchers report having pinpointed an area of the brain where three essential components of language — word identification, grammar,…
Taking nanomaterials to a new level of structural complexity, scientists have determined how to introduce kinks into arrow-straight nanowires, transforming them into zigzagging two- and three-dimensional structures with correspondingly advanced functions.
Cancer cells fueled by the mutant KRAS oncogene, which makes them notoriously difficult to treat, can be killed by blocking a more vulnerable genetic partner of KRAS, report scientists at…
A team of Harvard Stem Cell Institute researchers at Massachusetts General Hospital and collaborators at Harvard’s School of Engineering and Applied Sciences has taken a giant step toward possibly using human stem cells to repair damaged hearts.

China’s Hengduan Mountains are a biodiversity hotspot; so the Harvard Herbaria’s Dave Boufford and a team of colleagues went there and discovered 30 new species.
New research argues that the health of the population and the success or failure of many public health initiatives hinge as much on cultural and social factors as they do on doctors, facilities, or drugs.
Psychology Professor Marc Hauser dispels misconceptions about human and ape behavior with regard to patience, impulsiveness, and economic interactions in Harvard Museum of Natural History talk.

Scientists have deciphered the three-dimensional structure of the human genome, paving the way for new insights into genomic function and expanding our understanding of how cellular DNA folds at scales that dwarf the double helix.

Health officials learned enough during the spring’s first wave of swine flu to be confident about managing this fall’s expected second wave, despite a “sense of uneasiness” that hangs over the coming flu season, Harvard School of Public Health Dean Julio Frenk.
One hundred and fifty thousand species down, 1.65 million to go. That is the tally for the online Encyclopedia of Life (www.eol.org/), an ambitious two-year-old project with the goal of nothing less than documenting in one place all of the 1.8 million known living species on Earth and making the information available to everyone with Internet access.
