Dream home: Malaria parasite renovates to suit its tastes
...ole and the erythrocyte membrane. "It has been an enigma
in biology how the parasite transfers proteins across the second membrane, the parasitophorous vacuole, and establishes infection in the erythrocyte," said Cowman. "Once past the parasitophorous vacuole it can renovate the erythrocyte, obtain nutrien...
Extinctions linked to climate change
...er biological disruption. What had been seen as an enigma
is now understood as a complex relationship between global warming and major extinction of species. "This new study is a breakthrough, and the powerful synergy between pathogen transmission and climate change should give us cause for concern about h...
Scientists debate the neurobiological underpinnings of amnesia
... memory studies have thoughtfully reconsidered the enigma
of amnesia, as well as the methodological and conceptual problems in its study. They point out how studies of amnesia have been important in forming our current understanding of how memory works, and they propose novel ways of experimentally evaluati...
Researchers give name to ancient mystery creature
...y ladder is still unknown. Horolodectes remains an enigma
to this day. "It's just too bizarre to place in any group that we've known about previously," said Scott. "It's an open question until we can find more of it. We have no information from a skull or other parts of the body."...
Do you need sex to be a species?
...y 400 species. Bdelloids have remained an enduring enigma
in part because biologists are still debating whether the species actually exist as true evolutionary entities. And if they do, what forces determine how they diverge? In the traditional view of species diversification, interbreeding promotes cohesio...
Plants with male and bisexual flowers on the same plant are better mothers
...pread sexual strategy that remains an evolutionary enigma
is the production of both male and bisexual flowers in the same plant, which occurs in approximately 4000 species. What is the advantage of producing these redundant male flowers? Mario Vallejo-Marin and Mark Rausher, evolutionary biologists from Duk...
