CLIMATE CHANGE: Radar reveals meltwater's year-round life under Greenland ice
When summer temperatures rise in Greenland and the melt season begins, water pools on the surface, and sometimes disappears down holes in the ice. That water may eventually reach bedrock, creating a slipperier, faster slide for glaciers. But where does it go once it gets there, and what happens to it in the winter? A new study helps answer these questions.

CRISPI – RNA LONG NONCODING: [Research Article] CRISPRi-based genome-scale identification of functional long noncoding RNA loci in human cells
The human genome produces thousands of long noncoding RNAs (lncRNAs)—transcripts >200 nucleotides long that do not encode proteins. Although critical roles in normal biology and disease have been revealed for a subset of lncRNAs, the function of the vast majority remains untested. We developed a CRISPR interference (CRISPRi) platform targeting 16,401 lncRNA loci in seven diverse cell lines, includ

CLIMATE CHANGE – CO2: [In Depth] Fossil leaves bear witness to ancient carbon dioxide levels
There are lessons for climate scientists buried in the past. Carbon dioxide (CO2) levels surged many times millions of years ago, triggering ancient bouts of climate change. But the evidence is hazy: Models of ancient atmospheres and tools for teasing out past CO2 levels from fossils and rocks all have limitations. Now, scientists have developed a new method for wringing CO2 estimates from fossili

SUPERCONDUCTOR: [Perspective] The fragility of distant Cooper pairs
The first superconductor was discovered in 1911, when elemental mercury was cooled below the helium liquefaction temperature. Suddenly, it ceased to show any resistance to the flow of electricity.

One means by which cancer cells evade therapies involves their ability to reprogram to a cell type that no longer depends on the cellular pathway being targeted by the treatments.

DNA – DOUBLE STRAND BREAK: [Research Article] A global view of meiotic double-strand break end resection
DNA double-strand breaks that initiate meiotic recombination are exonucleolytically processed. This 5′→3′ resection is a central, conserved feature of recombination but remains poorly understood. To address this lack, we mapped resection endpoints genome-wide at high resolution in Saccharomyces cerevisiae. Full-length resection requires Exo1 exonuclease and the DSB-responsive kinase Tel1, but not

Current models of the peopling of the higher-elevation zones of the Tibetan Plateau postulate that permanent occupation could only have been facilitated by an agricultural lifeway at ~3.6 thousand calibrated carbon-14 years before present. Here we report a reanalysis of the chronology of the Chusang site, located on the central Tibetan Plateau at an elevation of ~4270 meters above sea level. The m

How does cortical tissue change as brain function and behavior improve from childhood to adulthood? By combining quantitative and functional magnetic resonance imaging in children and adults, we find differential development of high-level visual areas that are involved in face and place recognition. Development of face-selective regions, but not place-selective regions, is dominated by microstruct
PROSTATE CANCER – HORMONE THERAPY: [Report] Rb1 and Trp53 cooperate to suppress prostate cancer lineage plasticity, metastasis, and antiandrogen resistance
Prostate cancer relapsing from antiandrogen therapies can exhibit variant histology with altered lineage marker expression, suggesting that lineage plasticity facilitates therapeutic resistance. The mechanisms underlying prostate cancer lineage plasticity are incompletely understood. Studying mouse models, we demonstrate that Rb1 loss facilitates lineage plasticity and metastasis of prostate adeno
PROSTATE CANCER – HORMONE THERAPY: [Report] SOX2 promotes lineage plasticity and antiandrogen resistance in TP53- and RB1-deficient prostate cancer
Some cancers evade targeted therapies through a mechanism known as lineage plasticity, whereby tumor cells acquire phenotypic characteristics of a cell lineage whose survival no longer depends on the drug target. We use in vitro and in vivo human prostate cancer models to show that these tumors can develop resistance to the antiandrogen drug enzalutamide by a phenotypic shift from androgen recepto

BRAIN – NETWORK ANALYSES: Dense Associative Memory is Robust to Adversarial Inputs
Deep neural networks (DNN) trained in a supervised way suffer from two known problems. First, the minima of the objective function used in learning correspond to data points (also known as rubbish examples or fooling images) that lack semantic similarity with the training data. Second, a clean input can be changed by a small, and often imperceptible for human vision, perturbation, so that the resu
BRAIN – NETWORK ANALYSES: Encoding Sensory and Motor Patterns as Time-Invariant Trajectories in Recurrent Neural Networks
Much of the information the brain processes and stores is temporal in nature – a spoken word or a handwritten signature is defined as much by how it unfolds in time as by its spatial structure at any given moment in time. It remains unclear how neural circuits encode such patterns. We show that the same recurrent neural network model can simultaneously encode time-varying sensory and motor pattern

CLIMATE CHANGE: 2016 Edges 1998 as Warmest Year on Record
Globally, 2016 edged out 1998 by +0.02 C to become the warmest year in the 38-year satellite temperature record, according to scientists. Because the margin of error is about 0.10 C, this would technically be a statistical tie, with a higher probability that 2016 was warmer than 1998. The main difference was the extra warmth in the Northern Hemisphere in 2016 compared to 1998.
