Rickettsia Evades a Tense Situation

Organ donation in Germany: getting out of a tense situation

When the first German Transplantationsgesetz (Transplant Act) entered into force in 1997, post-mortem organ donation had reached an all-time low at 12.5 donors per million inhabitants. The Act was intended to create safety in core medical ethics issues and improve trust in transplant medicine – the beginning of a new era. The number of postmortem organ donors increased only slowly, and compared...

Annotating "tense" in a Tense-less Language

In the context of Natural Language Processing, annotation is about recovering implicit information that is useful for natural language applications. In this paper we describe a “tense” annotation task for Chinese, a language that does not have grammatical tense, that is designed to infer the temporal location of a situation in relation to the temporal deixis, the moment of speech. If successful...

E-cadherin evades endocytosis

E-cadherin evades endocytosis-cadherin interacts with other E-cadherin molecules on neighboring cells to form cell–cell adhesions. E-cadherin that is not involved in these trans interactions is removed from the cell surface and replaced with newly synthesized molecules to maintain dynamic adhesions. Now, Izumi et al. (page 237) show that E-cadherins that are involved in trans interactions are e...

Cellular Aging: Symmetry Evades Senescence

Cellular aging programs typically rely on the asymmetric shape and growth pattern of cells. A new study shows that symmetric fission yeast cells escape classic signs of aging until they encounter environmental stress.
