Teaching an old carbocation new tricks: Intermolecular C-H insertion reactions of vinyl cations
Vinyl carbocations have been the subject of extensive experimental and theoretical studies over the past five decades. Despite this long history in chemistry, the utility of vinyl cations in chemical synthesis has been limited, with most reactivity studies focusing on solvolysis reactions or intramolecular processes. Here we report synthetic and mechanistic studies of vinyl cations generated thro

Dirac-source field-effect transistors as energy-efficient, high-performance electronic switches
An efficient way to reduce the power consumption of electronic devices is to lower the supply voltage, but this voltage is restricted by the thermionic limit of subthreshold swing (SS), 60 millivolts per decade, in field-effect transistors (FETs). We show that a graphene Dirac source (DS) with a much narrower electron density distribution around the Fermi level than that of conventional FETs can

Episodic memories are encoded by a sparse population of hippocampal neurons.

Social regulation of insulin signaling and the evolution of eusociality in ants
Queens and workers of eusocial Hymenoptera are considered homologous to the reproductive and brood care phases of an ancestral subsocial life cycle.

Using a brain transcriptomics screen, we identified a single gene, insulin-like peptide 2 ( ilp2 ), which is always up-regulated in ant repro

Lectins modulate the microbiota of social amoebae
The social amoeba Dictyostelium discoideum maintains a microbiome during multicellular development; bacteria are carried in migrating slugs and as endosymbionts within amoebae and spores. Bacterial carriage and endosymbiosis are induced by the secreted lectin discoidin I that binds bacteria, protects them from extracellular killing, and alters their retention within amoebae.

A new study by researchers from the University of South Carolina in the US, led by Janice Probst and Saundra Glover, looks into the relationship between past occurrence of lynching — unpunished, racially motivated murder — and recent death rates.

Solution to medical mystery may help some children avoid bone marrow transplantation
Researchers have helped solve a decades-old mystery about which mutations are responsible for an inherited bone marrow disorder. The answer may allow some children to avoid the risk and expense of bone marrow transplantation, a common treatment for leukemia and bone marrow disorders. Investigators at St. Jude Children's Research Hospital and UCSF, led the study, which appears today in the scientif

UCalgary researchers discover why sepsis from a staph infection causes organ failure
Scientists have known for some time that one of the reasons a staph infection is so deadly is that the bacteria send out a toxin, known as Alpha Toxin (AT), which quickly worsens sepsis. University of Calgary scientists at the Cumming School of Medicine's Snyder Institute for Chronic Diseases have discovered the most important target of the toxin and how to neutralize the danger.

Next generation ALS drug silences inherited form of the disease in animal models
NIH-funded researchers delayed signs of amyotrophic lateral sclerosis (ALS) in rodents by injecting them with a second-generation drug designed to silence the gene, superoxide dismutase 1 (SOD1). The results suggest the newer version of the drug may be effective at treating an inherited form of the disease caused by mutations in SOD1.

Treatments for cancer and sickle cell disease deplete germ cells in young boys
Scientists have discovered that some treatments for cancer and sickle cell disease can destroy the germ cells that go on to develop into sperm in the testes of young boys. In some pre-pubescent boys, the treatment for sickle cell disease results in complete destruction of all their germ cells, which are called spermatogonia.

Highly magnified gravitationally lensed red quasar detected by astronomers
Astronomers have discovered a highly magnified, gravitationally lensed quasi-stellar object (QSO). The newly found quasar, designated W2M J104222.11+164115.3, is dust-reddened, and exhibits a significant flux anomaly. The finding is reported in a paper published July 14 on the arXiv pre-print server.
