Pancreatic intraepithelial neoplasia is a pre-malignant lesion that can progress to pancreatic ductal adenocarcinoma, a highly lethal malignancy marked by its late stage at clinical presentation and profound drug resistance. The genomic alterations that commonly occur in pancreatic cancer include activation of KRAS2 and inactivation of p53 and SMAD4 (refs 2, 3, 4). So far, however, it has been challenging to target these pathways...

Backed by Amazon and Paul Allen, KITT.AI launches first ‘hotword detection’ software toolkit
KITT.AI wants to help developers add voice activation features to almost any device for free.
The Seattle startup today unveiled its first software toolkit called Snowboy, which lets developers add verbal “hotword detection” to devices. It’s the same technology that tech giants like Amazon and Apple use for products like...
Detection of a Cooper-pair density wave in Bi2Sr2CaCu2O8+x
The quantum condensate of Cooper pairs forming a superconductor was originally conceived as being translationally invariant. In theory, however, pairs can exist with finite momentum Q, thus generating a state with a spatially modulated Cooper-pair density. Such a state has been created in ultracold 6Li gas but never observed directly in any superconductor. It is now widely hypothesized that the pseudogap phase of the...

Non-destructive state detection for quantum logic spectroscopy of molecular ions
Precision laser spectroscopy of cold and trapped molecular ions is a powerful tool in fundamental physics—used, for example, in determining fundamental constants, testing for their possible variation in the laboratory, and searching for a possible electric dipole moment of the electron. However, the absence of cycling transitions in molecules poses a challenge for direct laser cooling of the ions, and for controlling and detecting...

Big names gamble big bucks on blood tests for early cancer detection
Forget biopsies, ultrasounds, mammograms, pap smears, rectal exams, and other unpleasant cancer screenings—the race is now on for simple, affordable blood tests that can detect all sorts of cancers extremely early.
On Sunday, genetic sequencing company Illumina Inc. announced the start of a new company called Grail, which will join dozens of companies developing such blood tests. Toting big-name investors...
