In many projects there comes a time when you’ll need to store some data off-line. It may be a requirement or just an improvement for your users, but you have to decide which of the available storage options you will use in your application. This article will help you choose the best one, for your app.

Introduction

HTML5 introduced a few off-line storage options. AppCache, localStorage, sessionStorage and IndexedDB. Every one of them is suitable for a specific use. For example, AppCache can boost your application or let some parts of it work without an Internet connection. Below, I will describe all of these options and show a few code snippets with example usage.

A new study has discovered that the guts of elite athletes contain a particular type of bacteria that boosts exercise capacity. The bacteria are members of the genus Veillonella and are not present in the gut microbiomes of sedentary people.

The microbiome

The microbiome is an ever-changing ecosystem in the gut populated by a vast array of types of archaea, eukarya, viruses, and bacteria. Four microbial phyla, Firmicutes, Bacteroides, Proteobacteria, and Actinobacteria, make up 98% of the intestinal microbiome.

To finance the containment structure, the EBRD managed a fund with contributions from 45 countries, the European Union, and the bank’s own resources. Ukraine contributed 100 million euros (about $112 million).

Deputy project manager Victor Zalizetskyi, who has been part of construction and repairs at the Chernobyl plant since 1987, said he was “filled with pride” that he got to work on a job “that has such a big importance for all humankind.”

However, Zalizetskyi expressed concern in an interview last week that war-torn Ukraine might struggle to cover the maintenance costs for the reactor’s new enclosure. He noted that costly and complicated work such as dismantling unstable sections of the power plant still needs to be done.

Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond the capabilities of modern computers, so scientists at Princeton University have turned to an unusual branch of geometry instead.

Researchers led by Andrew Houck, a professor of electrical engineering, have built an electronic array on a microchip that simulates in a hyperbolic plane, a geometric surface in which space curves away from itself at every point. A hyperbolic plane is difficult to envision—the artist M.C. Escher used in many of his mind-bending pieces—but is perfect for answering questions about particle interactions and other challenging mathematical questions.

The research team used superconducting circuits to create a lattice that functions as a hyperbolic space. When the researchers introduce photons into the lattice, they can answer a wide range of difficult questions by observing the photons’ interactions in simulated hyperbolic space.

Those who had adhered to statin treatment vs those who had not were found to have 34% lower all-cause mortality rates. Fewer atherosclerotic cardiovascular disease events were reported in relation to adherence to statins. Irrespective of age and sex, reduced mortality and cardiovascular morbidity may be seen in older adults in relation to adherence to statins.

In a stunning scientific breakthrough, Yale School of Medicine researchers restored brain activity in pigs that had died hours before. The finding could revolutionize the neuroscience field and how scientists conceive the boundaries between life and death.

By circulating a cocktail of cell-rejuvenating compounds throughout the pigs’ brains, the researchers prevented tissue decomposition and restored some cell function. If replicated, their technique could be used as a model for drug testing and has implications for how scientists understand brain plasticity after traumatic events such as strokes.
