Twitter Hits 500 Million Registered Users

Twitter 'To Hit 500 Million Registered Users' -- The Telegraph

Twitter is set to hit 500 million registered users later today, according to a report.

The popular microblogging company, which processes more than a billion tweets a week, is set to hit the milestone figure later today, claims Twopcharts, a third party Twitter analysis company.

However, the 500 million relates to the total number of registered accounts, and fails to reveal how many are active.

A Twitter spokesman declined to comment on third party figures and said that the company only tracks how many active users there are using the site. There are no plans from the company to announce a registered user figure milestone.

Presently there are 100 million active Twitter accounts; a figure which was announced by the company’s executives last September.

Hepatitis C Is A Bigger Killer Than HIV

Hepatitis C-Related Deaths Outpace HIV Deaths, Study Says -- L.A. Times

Hepatitis C mortality rates surpassed HIV mortality rates in the United States in 2007, researchers said Monday.

In a study in the journal Annals of Internal Medicine (abstract here), U.S. Centers for Disease Control researchers analyzed causes of death on more than 21.8 million U.S. death certificates filed between 1999 and 2007. Rates of death related to hepatitis C, a viral infection that causes chronic liver disease, rose at an average rate of .18 deaths per 100,000 persons per year. More than 15,000 people died from hepatitis C in 2007. HIV-related death rates declined .21 deaths per 100,000 people per year — 12,734 people died from HIV in 2007. Rates of death related to a third infection, hepatitis B, remained more or less constant over the study period, falling .02 deaths per 100,000 people per year to just more than 1,800 deaths in 2007.

Intetnet Service Providers Warned By The FBI To Get Rid Of A Notorious Trojan Virus

FBI Plans To Shut Down Internet Servers Infected With Notorious Trojan -- New America

Computers experts around the world are warning that, in an attempt to stop the damage inflicted by a Trojan virus that has infected millions of computers worldwide, the FBI plans to shut down Internet Service Providers (ISPs) whose administrators have not yet cleared their systems of the malware.

As reported by PCWorld.com, in November 2011 the FBI shut down a network that a gang of criminal hackers in Estonia had launched to infect servers with the notorious DNSChanger Trojan — a virus that redirects computers from legitimate online destinations to phony websites that launch online ads that generated revenue for the hackers. The Trojan is sophisticated enough to prevent computers infected with the virus from visiting websites with the tools available to remove the problem.

DARPA's Plan To Revolutionize Auto Manufacturing

Adaptive Vehicle Make: DARPA's Plan To Revolutionize Auto Manufacturing -- Popular Mechanics

The Pentagon's mad scientists aim to throw out the way vehicles are currently built and replace it with a model in which parts could be 3D-printed, designs will be entirely digital, and the wisdom of the crowd will design the military's next vehicle.
The defense research group DARPA wants better vehicles, and it wants them faster and cheaper. To make it happen, the Pentagon's mad scientists are taking a cue from computer-circuit builders.

During the 1980s, the integrated-circuit-manufacturing industry began a sea change away from the traditional manufacturing model: Design was separated from manufacturing as a stand-alone function, with designers outsourcing manufacturing to dedicated fabrication plants, or fabs. The result has been an industry more responsive to the rapid pace of innovation that we all know and love today.

Is Quantum Computing Possible?

MIT Scientist Offers $100,000 to Anyone Who Can Prove Quantum Computing Is Impossible -- Popular Science

Scott Aaronson, a scientist at MIT who works mostly with theoretical quantum computers, issued a challenge to all of those deniers out there: prove that "scalable quantum computing is impossible in the physical world," and Aaronson will personally pony up $100,000 to the winner.

Aaronson works with quantum computing theory all day; sounds like he's sick of the constant chatter that quantum computing is not scalable, that the theory is purely theoretical. (Check out our interview with Seth Lloyd for a great beginner's guide to quantum computing.) There are as many skeptics as believers out there, so Aaronson is asking them to step up and prove that quantum computers will never be able to do useful work.

A Blood Test For Depressions

Blood Test Could Someday Diagnose Depression. U.S. Navy

Study Of The Day: Blood Tests Can Accurately Diagnose Depression -- The Atlantic

PROBLEM: Depression has traditionally been diagnosed with a questionnaire that assesses patients' reported symptoms. This process varies greatly, however, since it relies heavily on the clinician's experience and resources.

METHODOLOGY: To test if an objective biological test could improve diagnosis accuracy, scientists recruited 36 adults with major depression and 43 healthy participants for a blood screening. They measured the levels of nine biomarkers associated with depressive symptoms, such as inflammation, the development and maintenance of neurons, and the interaction between brain structures involved with stress response and other key functions.

A Bill Of Rights For Dolphins: They're So Smart We Must Treat Them As 'Non Human Persons' Say Scientists -- Daily Mail

Dolphins are so intelligent that they should be thought of as ‘non-human persons’ and given their own bill of rights, it is claimed.

A coalition of scientists, philosophers and animal welfare groups have come up with a declaration of dolphin rights which they hope will one day be enshrined in law.

This would stop them being kept in zoos and waterparks, and being attacked by fishermen.

Its Been 50 Years Since John Glenn Circled The Earth

50 Years Later, Celebrating John Glenn’s Feat -- New York Times

In the winter of 1962, the nation needed a hero.

Americans had yet to recover from the Soviet Union’s launching of the first spacecraft, Sputnik, in October 1957 — a rude jolt to our confidence as world leaders in all things technological. The space race was on.

Soon after he took office in 1961, President John F. Kennedy had thrown down the challenge to send men to the Moon by the end of the decade. But the Russians still set the pace, boastfully. They launched a dog into orbit, then the first man, Yuri A. Gagarin, and another, Gherman S. Titov.

The United States lagged, managing only two 15-minute suborbital astronaut flights — only five minutes of weightlessness each time.

Formula One Gets Ugly -- Sydney Morning Herald

In 1954 Ferrari produced the 553 Squalo, an aggressive, thrusting Formula one car named in Italian for the shark it resembled. In 1962, it released a road car called 250 GT Lusso, or Italian for "beautiful".

For 2012, Ferrari has given us the less evocatively named Platypus. Or rather, almost the entire F1 field has earned the sobriquet thanks to their misshapen, stepped nose sections that promise some of the ugliest-looking Formula one cars in years. F1ugly, in fact.

The Search For Dark Energy

The Dark Side Of The Universe -- The Economist

Scientists are trying to understand why the universe is running away from them.

AT FIVE tonnes and 520 megapixels, it is the biggest digital camera ever built—which is fitting, because it is designed to tackle the biggest problem in the universe. On February 20th researchers at the Cerro Tololo Inter-American Observatory (pictured), which sits 2,200 metres (7,200 feet) above sea level in the Atacama desert of northern Chile, will begin installing this behemoth on a telescope called Blanco. It is the centrepiece of the Dark Energy Survey (DES), the most ambitious attempt yet to understand a mystery as perplexing as any that faces physics: what is driving the universe to expand at an ever greater rate.

Will Diseases Soon Become 'Impossible To Treat'?

Experts Fear Diseases 'Impossible To Treat' -- The Independent

Alarming rise in bacteria resistant to antibiotics, Government report finds.

Britain is facing a "massive" rise in antibiotic-resistant blood poisoning caused by the bacterium E.coli – bringing closer the spectre of diseases that are impossible to treat.

Experts say the growth of antibiotic resistance now poses as great a threat to global health as the emergence of new diseases such as Aids and pandemic flu.

Professor Peter Hawkey, a clinical microbiologist and chair of the Government's antibiotic-resistance working group, said that antibiotic resistance had become medicine's equivalent of climate change.

Despite Bio-Terrorism Fears, H5N1 Research Will Be 'Eventually' Published

An image taken through an electronic microscope of the H5N1 virus, also known as the "bird flu." Virologist Ron Fouchier of the Erasmus Medical Center in Rotterdam has developed a new mutation of the H5N1 virus. Outside the lab, the disease has only been transmitted from animals to humans. Fouchier's mutation makes it airborne, creating the possibility of human-to-human transmission. CDC / dapd

WHO Delays Hugely Significant Decision On Whether To Publish Details Of Lethal Man-Made Flu That Could Kill Half The People It Infects -- Daily Mail

* H5N1 bird flu virus kills half of humans that contract it
* Research into more contagious forms of virus
* Editor says 'we have to publish in complete form'
* Insists publication is essential to create vaccine

The World Health Organisation has delayed its decision as to whether controversial research into a dangerous new man-made mutant form of the bird flu virus should be made public.

Scientists, health officials and science journal editors have this week been locked in talks on whether the study should be released amid fears it could be exploited by bioterrorists.

The controversial research shows how to make a mutant strain of the H5N1 virus, which kills roughly half of those who contract it, more contagious.
