Food For Tomorrow

By 2020 A.D.,Human beings will be compelled to look for other sources for their food.Mushroom may be grown artificially , because they reproduce principally by spores, sometimes producing these at the rate of 40,000,000. an hour.

Algae could be cultivated about thirty meters below  the surface of the sea by establishing special "farms". These algae could help reap a rich "harvest" of fish for man.

Yeast may be made to grow on petroleum and plastic wastes, which could then serve as food .Scientists at LAVERA, in France have proved that this is possible, you may not have to eat the sort of protein, extracted from petroleum waste, if the growth of population can be checked.

Disappearing act on POLL in Facebook

Dear Facebook,

I’ve always been a fan of your poll functionality – or ‘Question’ as you prefer to call it – on branded Facebook Pages. Being able to get fans to engage quickly and easily by one simple click was a great way of posing a pertinent question and taking an instant snapshot of how the community felt at that particular moment in time.

So imagine my surprise when I went to upload a question recently and found that the option to ask one had completely disappeared. Normally, I just click on Offer, Event + and the option to choose ‘Question’ would be right in front of me.

I wondered if it was unique to that page, so I tried the same sequence on several brand pages and, lo and behold, it had disappeared for them as well.

Next stop was a Google search to see if I had missed an important announcement about it. No. Nothing had been announced. Yes, there were stories about phasing it out for personal accounts – which is fair enough as I don’t think I’ve ever asked friends about their favourite TV programme – but definitely nothing about the feature going on branded Facebook Pages.

As TechCrunch stated in October 2012: “Facebook finally confirmed it is retiring Questions, which originally launched in July 2010. The Questions Dashboard and option to share a poll to the news feed are being removed. Questions will still be available in Groups and Pages.”

But it would appear that you, Facebook, have actually decided to pull it for Pages too.

Is this correct? If so, I’d like to know why. It was still there in your help centre  and there were still clear instructions on how to set a Question up.

I tapped up industry sources, and like me, no one had heard or read any formal announcement. However,  other community managers confirmed that their ability to post Questions had also disappeared.  One person even commented that she had written a training video on Tuesday 9 July and the functionality was there. But by Wednesday 10 July it had vanished!

Please bring it back, Facebook. It’s so useful to be able to get an unbiased view from a brand’s community.  A poll can capture the feeling at a particular moment in time, and we community managers can use that information to help inform our brands’ content and campaigns. As you well know, feelings can change over time and we need to regularly take the temperature of our community to keep it in good health.

So, if you are reading this, dear Facebook,  please us know what has happened to your poll functionality. We want it back!

PS In the short time between us asking the question, and writing our plea, AllFacebook succeeded in extracting an official statement from Facebook.

We’re no longer offering questions as an advertising product, or as a tool for all pages on Facebook, but we’re exploring the value questions bring to pages that produce public content — like news organizations, for example. Questions will remain as a tool for a small group of these types of pages, so that they can help us test a few improvements we’re making to the ways people and pages interact on Facebook.”

But we don’t think it’s game over yet.  Join us in calling for the return of Questions.

5 Sketchy Things We Still Don’t Know About E-Cigarettes

The FDA has cracked down on e-cigs by asserting its regulatory power and proposing a ban on sales to minors

On Thursday, the U.S. Food and Drug Administration (FDA) flexed its regulatory muscles and extended its authority over more tobacco products, including the highly debated electronic cigarettes, or e-cigarettes. In the announcement, the agency said it now has jurisdiction over items that meet the statutory definition of tobacco products—which includes e-cigarettes, pipe tobacco, and hookah tobacco, among others. The FDA says it also plans to crack down on e-cigarettes by proposing a ban of their sale to people under 18 and by requiring health warnings on packaging.

The UK already has stiff regulations on e-cigarettes and some cities in the U.S., like Los Angeles, have banned them in several public places. The trouble with e-cigarettes is that they are so new, and there’s not enough evidence to definitively determine either how effective they are at helping people quit smoking—or the health risks associated with inhaling vaporized nicotine. Here are five things we are still scratching our heads over.

1. Do e-cigarettes actually help people quit—or are they a gateway for new smokers? Some e-cigarette brands claim that they can help people wean themselves off regular cigarettes by supplying would-be quitters with nicotine (but without the carcinogens in conventional cigarette smoke). However, recent research is questioning whether they really help people quit. A recent study published in the journal JAMA Internal Medicine looked at self-reports from 949 smokers–88 of whom used e-cigarettes at the start of the study–in order to determine if e-cigarettes were helping people kick or cut back on nicotine. Researchers found that e-cigarettes did not help people quit, concluding, for now at least, that the case for e-cigarettes as a cessation tool is flimsy at best. (The study size was small, signaling a need for more research.)

There’s also the worry that e-cigarettes are tempting people into trying the real thing. Another study published in March found that adolescents who use e-cigarettes are more likely to smoke other tobacco products and regular cigarettes, which suggests that e-cigarettes are not always the lesser of two evils, but instead, just another vector for nicotine exposure. According todata from the National Youth Tobacco Survey, the percentage of middle school and high school students who have tried e-cigarettes doubled from 3.3% in 2011 to 6.8% in 2012. Of course, there are still not enough studies to reach a firm conclusion that e-cigarettes make people more likely to smoke tobacco—and the FDA says this is not yet determined.

2. How dangerous is liquid nicotine? The health risks associated with the liquid nicotine used in e-cigarettes are not fully understood. A recent New York Timesarticle found that the liquid could be linked to poisonings; the number of poisonings linked to e-cigarette liquids rose to 1,351 in 2013, which is a 300% increase from 2012. The CDC alsoreleased a report earlier this month that showed what they called a “dramatic” rise in e-cigarette-related calls to U.S. poison centers. The spike went from one call a month in September 2010 to 215 calls a month in February 2014. Over half of the calls involved kids age five and under, and 42% involved people ages 20 and older. Known symptoms of liquid nicotine ingestion include vomiting, nausea, and eye irritation.

3. Are the vaporizers safe? Though the numbers are small, there have been a few cases of e-cigarettes exploding and harming users and the people around them. E-cigs contain a small lithium battery that heats up the liquid inside. The liquid is made up of nicotine dissolved in a colorless liquid called propylene glycol, with added synthetic flavor and sometimes dyes. When an e-cigarette exploded in a Florida man’s face, Thomas Kiklas, co-founder of the Tobacco Vapor Electronic Cigarette Association, told the Associated Press that the industry does not know of issues with the cigarettes or batteries exploding.

4. Is propylene glycol dangerous? Propylene glycol is a a clear, colorless liquid that becomes vapor when it’s heated. It can also be found in food, cosmetics, and pharmaceutical products, and the small amounts people are typically exposed to are largely believed to be benign. However, it’s uncertain whether inhaling propylene glycol could come with unique health risks. “As for long-term effects, we don’t know what happens when you breathe the vapor into the lungs regularly,” Thomas Glynn, the director of science and trends at the American Cancer Society told ABC News. “No one knows the answer to that.”

5. Can you get addicted to e-cigarettes? As the FDA says, nicotine is “highly addictive.” The FDA saysthey still don’t know how much nicotine or other potentially harmful chemicals are being inhaled during e-cigarette use. Therefore, it’s hard to tell how much or little damage is being done.

Men biased towards women on Twitter

DDN Correspondent Posted on 24 Apr, 2014 at 01:24:PM

A New Study Has Found That Male Twitter Users Are Biased Towards Their Female Counterparts As Conversations Among Men On The Microblogging Site Feature Fewer Mentions Of Women.

An algorithm was used by the researchers to apply the Bechdel test to real-life conversations via Twitter and to relate these to the gender bias of movies. The Bechdel Test was developed in 1985 by US cartoonist Alison Bechdel and it is used to see whether a movie features a minimum of female independence. 
Twitter users from the US were selected by the researchers and the users were those who shared the link to a movie trailer on YouTube over the course of six days in June 2013. They also analyzed the users who interacted with them over a longer period of time. Around 300 million tweets were given the form of a gigantic movie script with 170,000 characters by the researchers and then analyzed by them.


The analysis showed that Twitter conversations among men featured fewer mentions of women, while there were more conversations between female Twitter users that have references to men than conversations without a male reference. The researchers said that a male bias was however not found in all Twitter users. 

"I expected that on Twitter men would mention women in their conversations as often as women mentioned men," said David Garcia, researcher at the Chair of Systems Design at ETH Zurich.

Apple earnings preview: Second quarter may test investors' patience

Apple Chief Executive Tim Cook speaks before a new-product introduction in Cupertino, Calif. (Marcio Jose Sanchez / Associated Press / September 10, 2013)
By Chris O'Brien
April 23, 2014, 6:48 a.m.
Three months ago, when Apple reported its holiday earnings, the company posted record revenues thanks to refreshed lines of iPads and iPhones that had launched in the fall.

But instead of basking in a big win, Apple got pounded by Wall Street because of what the company said would happen in this current quarter. Apple projected a range of revenue expectations that raised the possibility of its first revenue decline in more than a decade.

Apple is scheduled to report second-quarter earnings after the markets close Wednesday, and most analysts think the company will actually squeak out a slight revenue gain. And since the last earnings call, Apple's stock has recovered most of its losses, closing Tuesday at $531.7, up from a dip below $500 a couple months ago.

Still, investors and analysts are not exactly bubbling with optimism about Apple these days. They seem resigned to the fact that the days of rocket-like growth of iPhone and iPad sales are over. Indeed, more than half the analysts polled by Fortune expected that Apple would report that iPad sales declined in the March quarter.

The company itself forecast revenue of $42 billion to $44 billion for the quarter, compared with $43.6 billion for the same quarter a year ago. Currently, Wall Street's consensus estimate is around $43.62 billion for the quarter.

On the profits side, Wall Street is expecting earnings of $10.22 per share, compared with $10.09 a year ago. The increase is due in large part to Apple's increasingly aggressive stock buyback program.

Analysts have accepted the fact that Apple is going to continue to focus on the higher-end, premium market for gadgets. Last year, many were hoping and expecting the company to unveil a lower-priced iPhone in order to be more competitive overseas and at least stem its market-share losses to Android.

But with Chief Executive Tim Cook making it clear that Apple would continue to focus on quality over quantity of units sold, most analysts have stopped talking about a cheaper iPhone.

"We see Apple as a provider of premium priced electronics, a lucrative market but one that may not sustain its current market valuation of $473 billion in the years ahead," Colin Gillis, an analyst at BGC Financial, wrote in a note to clients this week.

In the short term, that has some Apple watchers growing more pessimistic. Brian White, a Cantor Fitzgerald analyst, lowered his outlook for the current quarter that ends in June. Instead, like many analysts, he's looking ahead to the second half of the year, when he hopes some much-rumored new products such as a bigger iPhone will materialize.

"In our view, the ramp of the iPhone 6 (4.7-inch and 5.5-inch "iPhad"-like device) and iWatch in the second-half of CY:14 are more important than Apple's 2Q:FY14 performance and potentially soft 3Q:FY14 outlook," he wrote in a note to clients.

Analyst Gene Munster of Piper Jaffray was a bit more optimistic about Apple's earnings for the second quarter, expecting the company to report $44 billion, close to the high end of its range. But he's also expecting Apple to forecast 5% growth for the current quarter, below the 8% Wall Street currently expects.

Of course, there's almost zero chance that Cook will say anything about new products Wednesday. Most likely, Apple watchers will have to wait for its World Wide Developers Conference in June for any talk of updates or new products.

The question for Apple is how long investors will be content to ride out a quiet period until those mythical new products appear.
