Twitter (for iPhone)


Despite recent user uproar over the loss of Instagram images displaying on Twitter (photos posted via Instagram now open in a separate window), Twitter remains one of the most active and attractive social networks. And the mobile experience is key to its success. The official Twitter iPhone app (free) balances simplicity with essential features, such as the ability to maintain more than one account from the app, well enough to keep it relevant among contenders. It also doesn't hurt that Twitter purchased its main competitor TweetDeck thus preventing that app from outpacing its own.

Stability and reliability also count for something, and, while Twitter delivers well enough on both counts, it's still far from perfect on either?that's a big reason we've scored Twitter a four out of five stars. Drafted tweets sometimes hang in the ether until you delete them and start afresh. The site goes down from time to time. But, all in all, the app loads and refreshes quickly and smoothly, particularly on Apple's Phone 5, with the help of that amazing little A6 processor.

Professional social media-ites, however, continue to load their smartphones with a social aggregator app, such as Hootsuite (free, 4 stars) or Seesmic, a one-stop-shop for keeping pace with not just multiple Twitter accounts, but multiple accounts across various social networks.

Design and New Features
A clean user experience and smart design put the Twitter iPhone app in the big leagues. In the early days of Twitter, its own apps weren't as competitive and feature-rich as those third parties built for the 140-character network. The iPhone app was Twitter's first mobile version to fully mature, and after five major iterations (this review looks at version 5.2) the official Twitter-branded app is the way to go for many users. Best of all, if you don't have a Twitter account and aren't interested in joining, you can still use the app to search and read the site.

No Account and Multi-Account Features
After downloading and installing the Twitter app from the iTunes Store, you can start using the app immediately, even before you authenticate an account. The app mimics Twitter's website by allowing even non-members to search and read the site, a token feature that will surely win over lurkers far and wide.

More likely than not, though, if you're downloading the app, you do have a Twitter user name and password, and perhaps more than one. Sign in with one of them to start. To add more accounts, you first have to be logged in?then tap the options button (three circles at bottom right), select Accounts & Settings, and use the plus sign at the top right to add more accounts). After you've set up all your accounts, you can toggle between them using the Accounts button. Switching among accounts is easy, fast, and efficient.

Design and Photo Effects
Rather than bombard your eyes with a cacophony of color, the Twitter app sticks to a more sophisticated color scheme of black and white, reserving muted shades of digital bluebird blue for the top spanner only. It looks practical without being too serious, a simple design that takes into consideration the growing number of business users and content on the site. The app's look is sharp enough to still be appealing to people who use Twitter for personal or casual reasons, too.

A nice touch on the interactive side: Double-tapping the home icon at the lower left forces the window to scroll back to the top automatically, which means less finger flicking for users.

The newest feature, photo filters, mimics the basic functionality of photo-sharing site Instagram to a large extent, and it's only available on Twitter's mobile apps, not the website. Snap a photo using your iPhone, and Twitter offers dramatic filter effects, cropping and resizing tools, and an auto-enhance button.

Twitter has eight photo effects in all: vignette, black and white, warm, cool, vintage, cinematic, happy, and gritty. A ninth option in the interface is "No Filter," which I'm going to say doesn't count. You can see all the photo filters applied to the same image in a grid, helping you decide which one is best among your choices, which is quite different from the Instagram experience in which you swipe through previews but can't see side-by-side comparisons. Twitter also does offer the ability to page through the images one by one in a slideshow, if you prefer (I don't).

Drafts
Each account has its own options panel, where you can access your profile, account settings, user lists that you follow, favorite tweets, and drafts of tweets that haven't been sent yet. Drafts would be one of my favorite features of the Twitter app, except that it's slightly confusing when you look at the options that are available.

It seems as if you can enter the draft area and write a message (pen-on-paper icon) to save as a draft. But once you compose your message, the options are "send" or "cancel." There's no "save as a draft" immediately apparent; there is an option to "save as draft" if you select cancel, but I hate that it's not where I expect it to be. If you select send, the message goes live immediately. Tweets also save as drafts when the site goes down or you have connectivity problems. But in my experience, these drafts can sometimes hang in limbo for eternity, never posting no matter how long I wait after regaining service. All that's left to do is copy the text, delete the original message, and paste the content into a new tweet.

Twitter's iPhone app doesn't have the ability to schedule tweets to post at another date and time, a highly desired feature. Social media power users who need this feature can find it in an aggregation app, like Hootsuite and Seesmic.

The Twitter-Branded App
The official Twitter app for iPhone is a well-established and reliable app for the site, and it will be the one I continue to use for my Twitter account. It loads and refreshes quickly, seldom crashes, and covers the essential things a non-professional tweeter would want to do on Twitter from an iPhone, like post photos and receive notifications of new @ messages. It's not flooded with features, as some of the aggregator apps are, but balances goodies with functionality well for a mobile app.

The Twitter app for iPhone is ideal for average or casual Twitter users, but for handling accounts across multiple social media sites?such as Facebook, Foursquare, LinkedIn, and the rest?aggregator tools like Hootsuite and Seesmic are still more efficient. Professional tweeters should stick with those apps.

Structural studies of a toxin from Bacillus cereus that causes diarrhea

Jan. 4, 2013 ? Food poisoning caused by Bacillus cereus can lead to diarrhea which is probably caused by a 3-component toxin which is produced by this bacteria strain and which perforates and kills cells. New doctoral research has revealed one of the protein structures of this toxin and has led to a better understanding of the mechanisms behind multi-component, pore-forming toxins. These findings can enhance food safety.

Bacteria produce toxins in order to defend themselves and to gain nourishment. Pore-forming toxins make up about a third of all bacterial toxins. These toxins kill cells by making holes in the cell walls, so causing leakages and swelling which in turn leads to the disintegration of the cells. The most common pore-forming toxins consist of one protein and in some special cases, of two proteins.

Toxins which consist of three proteins (3-component) are extremely rare. The bacterium Bacillus cereus produces two such 3-component toxins. One of them is non-hemolytic enterotoxin, also known as Nhe. It is believed that this toxin is the major food poisoning toxin produced by B. cereus. It is found in all B. cereus strains that cause food poisoning and in nearly all other B. cereus strains. The three proteins in the Nhe toxin are called NheA, NheB and NheC.

In the course of her doctoral research, Danh Phung discovered the crystalline structure of one of the proteins in the Nhe toxin: NheA. This protein is the least studied of this toxin complex, but its presence is essential in order to achieve full cellular toxicity and pore formation. Phung's study is also the first to show that the Nhe proteins form structures resembling pores.

The way the Nhe toxin works is not fully understood. Phung showed that NheB, which is believed to be the most important protein in this toxin complex, forms pore-like structures of itself and produces large amounts of molecules by means of an artificial cell membrane, for example a lipid. These findings indicate that the NheB protein undergoes structural changes before the pore-forming process, which involves the other Nhe-proteins, begins.

Danh Phung carried out her doctoral research at the Norwegian School of Veterinary Science in collaboration with the Sir Hans Krebs Institute at the University of Sheffield in the UK.

M.Sc. Danh Phung defended her doctoral research on 18th December 2012 at the Norwegian School of Veterinary Science (NVH) with a thesis entitled "Structure and mode of action on the Nhe enterotoxin from Bacillus cereus."

House may not vote on any fiscal cliff deal before January 1

During an oddly jokey statement at the White House as the fiscal deadline bore down Monday afternoon, President Obama said, "I'm going to be president for the next four years. I?hope." He was warning Republicans that, yes, they'd have to deal with him for a while. But it was, to be sure, a strange moment. Could he actually have been joking about assassination? About impeachment? The?apocalypse? Or has everyone just had enough of these negotiations??
