The study of multi-moda. communica.ion ha. only recently been extended to inna.e a.d lea.ned intera.tions between flowers a.d their a.ima. visitors, a.d usua.ly only to pollina.ors. Here we studied the releva.ce of flora. scent a.d visua. displa. of a.night blooming, puta.ively ha.kmoth-pollina.ed pla.t Oenothera.a.a.lis （Ona.ra.ea.） in the a.tra.tion of non-na.ive cockroa.hes Bla.ta.orienta.is （Bla.todea. Bla.tida.）, which function a. fa.ulta.ive flora. la.cenists in coa.ta. ha.ita.s of centra. Chile. We experimenta.ly decoupled visua. （corolla. a.d olfa.tory （fra.ra.ce） stimuli by presenting pa.er corolla. a.d green mesh ba.s, with or without a.freshly-picked na.ura. flower inside. We then contra.ted the beha.iora. responses of roa.hes in these trea.ments with those to the na.ura. combina.ion of tra.ts in a.tua. flowers a.d their respective control trea.ments, mea.uring the roa.hes＇ frequency of first visits, mea. a.d tota. residence time spent in ea.h trea.ment. The roa.hes prima.ily used olfa.tory cues when a.proa.hing O. a.a.lis flowers a. two biologica.ly releva.t spa.ia. sca.es. In a.dition, the presence of conspecific roa.hes ha. a.strong influence on recruitment to the experimenta. a.ena. increa.ing the sta.istica. differences a.ong trea.ments. Our results suggest a.prima.y of flora. fra.ra.ce over visua. stimuli in the fora.ing responses of B. orienta.is. Olfa.tory cues were necessa.y a.d sufficient to a.tra.t the roa.hes, a.d the visua. cues presented in our ma.ipula.ions only ma.gina.ly increa.ed their a.tra.tion within a.20 cm dia.eter of the stimulus. The full spectrum of flora. visita.ion beha.ior wa. not elicited by the a.tificia. flowers, suggesting the need for a.ditiona. ta.tile or conta.t chemosensory stimuli not provided by pa.er. a.though the nitrogenous scent compounds tha. we found in O. a.a.lis flowers a.e a.most exclusively found in ha.kmoth-pollina.ed flowers, the a.tra.tiveness of these compounds to a.non-na.ive, fa.ulta.ive flower-visiti

The high levels of some meta.s in meta. hypera.cumula.or pla.ts ma. be tra.sferred to insect a.socia.es. We surveyed insects collected from the South a.rica. Ni hypera.cumula.or Berkheya.coddii to document whole-body meta. concentra.ions （Co, Cr, Cu, Mg, Mn, Ni, Pb, Zn）. We a.so documented the concentra.ions of these meta.s in lea.es, stems a.d inflorescences, finding extremely eleva.ed levels of Ni （4 700-16 000μg/g） a.d high va.ues （5-34μg/g） for Co, Cr, a.d Pb. Of 26 insect morphotypes collected from B. coddii, seven heteroptera.s, one coleoptera., a.d one orthoptera. conta.ned rela.ively high concentra.ions of Ni （〉 500μg/g）. The la.ge number of high-Ni heteroptera.s a.ds to discoveries of others （from Ca.ifornia.USa.a.d New Ca.edonia. a.d suggests tha. members of this insect order ma. be pa.ticula.ly Ni tolera.t. Nymphs of the orthoptera. （Stenoscepa. conta.ned 3 500 μg Ni/g, the grea.est Ni concentra.ion yet reported for a. insect. We a.so found two beetles with eleva.ed levels of Mg （〉 2 800 μg/g）, one beetle with eleva.ed Cu （〉 70 μg/g） a.d one heteroptera. with a. eleva.ed level of Mn （〉 200 μg/g）. Our results show tha. insects feeding on a.Ni hypera.cumula.or ca. mobilize Ni into food webs, a.though we found no evidence of Ni bioma.nifica.ion in either herbivore or ca.nivore insect ta.a. We a.so conclude tha. some insects a.socia.ed with hypera.cumula.ors ca. conta.n Ni levels tha. a.e high enough to be toxic to vertebra.es.

Mecha.istic study of substra.e-ba.ed ga.va.ic repla.ement rea.tions

The sa.rificia. templa.es used in ga.va.ic repla.ement rea.tions dicta.e the properties of the hollow meta. na.ostructures formed. Here, we demonstra.e tha. substra.e-ba.ed a.-a. na.oshells with ra.ica.ly a.tered properties a.e obta.ned by merely coa.ing silver templa.es with a. ultra.hin la.er of gold prior to their insertion into the rea.tion vessel. The so-formed na.oshells exhibit much smoother surfa.es, a.higher degree of crysta.linity a.d a.e fa. more robust. Dea.loying the na.oshells results in the first demonstra.ion of substra.e-ba.ed na.oca.es. Such ca.es exhibit a.well-defined pa.tern of geometric openings in directions corresponding to the {111}-fa.ets of the sta.ting templa.e ma.eria.. The a.ility to engineer the ca.e geometry through a.justments to the orienta.iona. rela.ionship between the crysta. structure of the sta.ting templa.e a.d tha. of underlying substra.e is demonstra.ed. Together these discoveries provide the fra.ework to a.va.ce our understa.ding of the mecha.isms governing substra.e- ba.ed ga.va.ic repla.ement rea.tions.

Tra.scription fa.tor networks ha.e evolved in order to control, coordina.e, a.d sepa.a.e, the functions of distinct network modules spa.ia.ly a.d tempora.ly. In this review we focus on the MYC network （a.so known a. the Ma.-MLX Network）, a.highly conserved super-fa.ily of rela.ed ba.ic-helix-loop-helix-zipper （bHLHZ） proteins tha. functions to integra.e extra.ellula. a.d intra.ellula. signa.s a.d modula.e globa. gene expression. Importa.tly the MYC network ha. been shown to be deeply involved in a.broa. spectrum of huma. a.d other a.ima. ca.cers. Here we summa.ize molecula. a.d biologica. properties of the network modules with empha.is on functiona. intera.tions a.ong network members. We suggest tha. these network intera.tions serve to modula.e growth a.d meta.olism a. the tra.scriptiona. level in order to ba.a.ce nutrient dema.d with supply, to ma.nta.n growth homeosta.is, a.d to influence cell fa.e. Moreover, oncogenic a.tiva.ion of MYC a.d/or loss of a.MYC a.ta.onist, results in a. imba.a.ce in the a.tivity of the network a. a.whole, lea.ing to tumor initia.ion, progression a.d ma.ntena.ce.
