The Food and Drug Administration on Thursday announced a series of restrictions aimed at combating a growing public health menace — flavored e-cigarettes and tobacco products that have lured young people into vaping and smoking. And in a bold regulatory move, the agency said it would move to outlaw two traditional tobacco products that disproportionately

PIWI-interacting RNAs: small RNAs with big functions PIWI-interacting RNAs: small RNAs with big functions, Published online: 16 November 2018; doi:10.1038/s41576-018-0073-3 PIWI-interacting RNAs (piRNAs) have numerous crucial biological roles, particularly transposon silencing in the germ line. In this Review, the authors describe our latest understanding of piRNA biogenesis and functions across diverse species, highlighting how, despite

Antarctica’s Shackleton Ridge at sunset.NASA/John Sonntag It’s hard to imagine, but Antarctica wasn’t always covered in ice. This huge continental landmass, back in the age of the dinosaurs, was a lush forested landscape, teeming with large creatures and critters alike. Nowadays, shielded by the largest ice sheet on the planet, we are only beginning to

Abstract Cytoplasmic flows are an ubiquitous feature of biological systems, in particular in large cells, such as oocytes and eggs in early animal development. Here we show that cytoplasmic flows in starfish oocytes, which can be imaged well with transmission light microscopy, are fully determined by the cortical dynamics during surface contraction waves. We first

Most of us learn how to ride a bike during childhood. But as we grow older, many of us stop riding and put those once-beloved bikes in storage. Years later, when we discover these relics and hop on, it’s as if we never stopped biking. This is surprising because our memories let us down in

The analysis of transcriptome data from non-model organisms contributes to our understanding of diverse aspects of evolutionary biology, including developmental processes, speciation, adaptation, and extinction. Underlying this diversity is one shared feature, the generation of enormous amounts of sequence data. Data availability requirements in most journals oblige researchers to make their raw transcriptome data publicly

In this work, we describe a novel machine learning method to predict protein binding affinity using protein sequence and structure information. Previously, various machine learning models have been developed for this purpose using standard machine learning approaches using sequence or structure information. Typically, structure-based methods generate better predictions than sequence-based ones but are limited by

Night by night, star by star, astronomers are edging ever closer to learning just how crowded our universe really is—or at least our galaxy, anyway. A quarter century after the first exoplanets were found orbiting other stars, statistics from the thousands now known have revealed that, on average, each and every stellar denizen of the

Wind farms are popping up all over the world. In the U.S. alone wind power capacity has tripled over the last decade. Although this trend is good news for efforts to curtail emissions and climate change, a growing body of research suggests wind turbines disturb their local environment in a significant way.
