Now that scientists understand what triggers key steps in the immune response to menacing fungi such as Candida albicans, they hope to develop ways to make it work better.

PROVIDENCE, R.I. [Brown University] — Every year, fungal infections threaten thousands of patients — from those with depressed immune systems to others who have had surgeries or devices such as catheters implanted. Moreover, some anti-fungal medications are beginning to lose their power. (more…)

Tübinger Biologen weisen den „parentalen Umwelteffekt“ in der Praxis nach – und wie dieser evolutionär entsteht

Pflanzen können nicht nur Genvarianten an ihre Nachkommen weitergeben, sondern auch Informationen über Umwelterfahrungen, die sie selber gemacht haben. Dieses Phänomen wird als „parentaler Umwelteffekt“ bezeichnet, er wird sowohl von Klimabedingungen als auch von der Pflanzendichte beeinflusst, also dem Maß, in dem Pflanzen um Ressourcen konkurrieren.
