LATEST NEWS Nanoscale negative refractionRefraction is a familiar effect in which a light beam alters direction as it propagates from one medium to another. Negative refraction is a nonintuitive but well-established effect in which the light beam is bent in the “wrong” direction. Two groups now independently demonstrate negative refraction at the interface of two-dimensional van der Waal materials. Hu et al.

LATEST NEWS Debate resolved? Teleost (or “ray-finned”) fishes make up half of all vertebrates, but there has been long-standing debate about their early evolution. Using new genomes from fishes in the basal group that includes tarpons and eels, as well as approaches that integrate patterns of genome structure not just sequence, Parey et al. show that this group forms a monophyletic lineage within another group that includes the arapaima and elephant nose fishes.

LATEST NEWS AbstractCertain Inhibitors of apoptosis (IAP) family members are sentinel proteins preventing untimely cell death by inhibiting caspases. Antagonists including second mitochondria-derived activator of caspase (SMAC) regulate IAPs, driving cell death. Baculoviral IAP repeat-containing protein 6 (BIRC6), a giant IAP with dual E2/E3 ubiquitin ligase activity, regulates programmed cell death through unknown mechanisms.

LATEST NEWS Catching out cap snatchingSome virus families hijack part of their hosts’ RNA to enable their own replication in a process called cap snatching. Before they can enact a snatch, influenza viruses specifically require host cap maturation by a host methyltransferase called MTr1. Tsukamoto et al. screened a compound library and found that trifluoromethyl-tubercidin (TFMT) inhibits host Mtr1 and suppresses virus replication.

A slow-motion crisis is underway among graduate students and postdocs in the United States who comprise today’s indispensable research and teaching workforce and tomorrow’s scientific leaders. Low pay, lack of benefits, and sometimes toxic research environments have persisted for years. Frustrated graduate students, postdocs, and nontenured faculty are protesting and pursuing unionization to address worsening conditions.
