Edward Snowden says he plans to develop and promote anti-surveillance technology to hamper government spying across the globe.

The former US National Security Agency (NSA) contractor, who leaked confidential documents detailing the extensive surveillance activities of the NSA and the UK's GCHQ, called for support at the Hackers On Planet Earth (HOPE) conference via a video link from Moscow, Russia.

Snowden addressed the conference on Saturday, requesting that the hacking community channel its resources into developing anti-surveillance technologies which will make government spying more difficult - and said that he planned to spend much of his future time doing the same.

The former NSA contractor said:
We the people - you the people, you in this room right now - have both the means and the capability to improve the future by encoding our rights into programs and protocols by which we rely every day. [..] and that's what a lot of my future work is going to be involved in, and I hope you'll join me in making that a reality.

No thanks: This photo from the Insect Museum of West China shows the largest aquatic insect ever found, discovered recently in a mountain of Chengdu. When they are larvae they spend a lot of time out of sight in the water, only leaving when they pupate and they become adults. They can be found in or near lakes and ponds
* The largest aquatic insect in the world has been found in Chengdu, China

* It is of the order Megaloptera and has a wingspan of 8.3 inches (21 cm)

* This is larger than the previous record, which stood at 7.5 inches (19 cm)

* The giant insect has huge mandibles that it uses during mating

* Can be found near wet environments such as lakes but lives just a few days

A newly discovered member of the Megaloptera family has been found that could be the largest aquatic insect in the world.

It was found on a mountain in Chengdu, Sichuan province in China.

The mysterious specimen of which little is known has a wingspan of 8.3 inches (21 centimetres).

On July 23, 2012, the sun unleashed two massive clouds of plasma that barely missed a catastrophic encounter with the Earth's atmosphere. These plasma clouds, known ascoronal mass ejections (CMEs), comprised a solar storm thought to be the most powerful in at least 150 years.

"If it had hit, we would still be picking up the pieces," physicist Daniel Baker of the University of Colorado tells NASA.

Fortunately, the blast site of the CMEs was not directed at Earth. Had this event occurred a week earlier when the point of eruption was Earth-facing, a potentially disastrous outcome would have unfolded.

Baker tells NASA:
"I have come away from our recent studies more convinced than ever that Earth and its inhabitants were incredibly fortunate that the 2012 eruption happened when it did."
"If the eruption had occurred only one week earlier, Earth would have been in the line of fire."

UK decriminalizes online file sharing of video games, music and films

The British government has decriminalized the act of online video game, music and film piracy, after branding harsher punishment plans as "unworkable."

Beginning in 2015, internet users who persistently file-share will be sent a series of warning letters explaining that their actions are illegal. However, authorities will take no further action if the user continues downloading the material.

The aim of the letters is to boost consumer awareness of the array of legitimate online media outlets such as Netflix, and deter people from using file-sharing software.

The new scheme, named the 'Voluntary Copyright Alert Programme (VCAP),' came after years of talks between internet service providers (ISPs), politicians, and the music and film industries.

Major ISPs, including BT, Virgin, and Sky, have already signed up to VCAP. Other ISPs are expected to follow suit.

Geoff Taylor, chief executive of UK music trade body BPI, said VCAP was about "persuading the persuadable, such as parents who do not know what is going on with their net connection."

Comment: Not only is criminalizing online piracy unworkable, it seems the effect on the industry is minimal at any rate.

A federal judge has denied Google Inc's attempt to dismiss a privacy lawsuit brought against the technology giant for commingling user data across its different products and offering that data to advertisers without permission.

US District Judge Paul Grewal ruled Monday evening that Google has to face the breach of contract and fraud claims brought by users of Android devices who downloaded at least one Android application through Google Play.

"Like Rocky rising from Apollo's uppercut in the 14th round, plaintiffs' complaint has sustained much damage but just manages to stand," Grewal wrote in a 28-page decision, referring to the 'Rocky' film series while alluding to how close his decision ultimately was. Two earlier versions of the lawsuit were previously dismissed by Grewal.

Grewal did dismiss on Monday other aspects of the current lawsuit, including claims brought by users who say they were compelled to switch away from Android devices to non-Android devices after Google altered its privacy policy in 2012 that allowed the data commingling.

Scientists cut HIV out of human genome using enzymes

US scientists have physically cut the HIV virus out of infected cells by using enzymes. The method could, in theory, lead to a permanent cure for AIDS, though researchers warn there is still a long way to go.

Scientists from Temple University School of Medicine in Philadelphia have pioneered a technique which uses a targeting strand of RNA (called guide RNA, or gRNA) that locates the virus. A "DNA snipping" enzyme (called a nuclease) then removes it from the infected cell. The cell, now free of the HIV virus, then repairs itself.

Cells armed with the nuclease-RNA combination proved impervious to HIV infection, the research states.

"This is an important step on the path toward a permanent cure for AIDS. It's an exciting discovery, but it's not yet ready to go into the clinic. It's a proof of concept that we're moving in the right direction," said Dr. Khalili, director of the Comprehensive NeuroAIDS Center at Temple and lead author of the study.

The editing process was successful in several cell types that can harbor HIV-1, including microglia and macrophages, as well as T-lymphocytes. "T-cells and monocytic cells are the main cell types infected by HIV-1, so they are the most important targets for this technology," Khalili said.

A security researcher considered to be among the foremost experts in his field says that more than a half-billion mobile devices running Apple's latest iOS operating system contain secret backdoors.

Jonathan Zdziarski, also known by his online alias "NerveGas," told the audience attending his Friday morning presentation at the Hackers on Planet Earth conference in New York City that around 600 million Apple devices, including iPhones and tablets, contain hidden features that allow data to be surreptitiously slurped from those devices.

During Zdziarski's HOPE presentation, "Identifying Backdoors, Attack Points and Surveillance Mechanisms in iOS Devices," the researcher revealed that several undocumented forensic services are installed on every new iPhone and iPad, making it easier that ever for a third-party to pull data from those devices in order to compromise a target and take hold of their personal information, including pictures, text messages, voice recordings and more.

Study finds over 100 genes linked to schizophrenia

Researchers identified more than 80 previously undiscovered genes which may be related to the development of schizophrenia, bringing the total of potentially associated genes to over 100, the largest international study ever published on the subject says.

"We identify 128 independent associations spanning 108 conservatively defined loci that meet genome-wide significance, 83 of which have not been previously reported," the abstract of the study, published in Nature magazine on Tuesday, states.

The findings are the result of the collaboration of Psychiatric Genomics Consortium (PGC), which included more than 80 institutions such as the Broad Institute of Harvard and MIT, Massachusetts General Hospital (MGH), and others around the world.

The identification of specific triggers which could lead to schizophrenia help boost the development of new ways to treat the mental illness, which has been stalling for the last 60 years, according to Michael O'Donovan, a psychiatrist who led the study from the UK's Cardiff University.

Schizophrenia is known to impact one in 100 people. Characteristics of the disease include hallucinations and delusions. Some patients hear voices and report symptoms of paranoia.

As above, so below? Horseshoe crabs harvested for their blue blood

The thing about the blood that everyone notices first: It's blue, baby blue. The marvelous thing about horseshoe crab blood, though, isn't the color. It's a chemical found only in the amoebocytes of its blood cells that can detect mere traces of bacterial presence and trap them in inescapable clots.

To take advantage of this biological idiosyncrasy, pharmaceutical companies burst the cells that contain the chemical, called coagulogen. Then, they can use the coagulogen to detect contamination in any solution that might come into contact with blood. If there are dangerous bacterial endotoxins in the liquid - even at a concentration of one part per trillion - the horseshoe crab blood extract will go to work, turning the solution into what scientist Fred Bang, who co-discovered the substance, called a "gel."

"This gel immobilized the bacteria but did not kill them," Bang wrote in the 1956 paper announcing the substance. "The gel or clot was stable and tough and remained so for several weeks at room temperature."

If there is no bacterial contamination, then the coagulation does not occur, and the solution can be considered free of bacteria. It's a simple, nearly instantaneous test that goes by the name of the LAL, or Limulus amebocyte lysate, test (after the species name of the crab, Limulus polyphemus). The LAL testreplaced the rather horrifying prospect of possibly contaminated substances being tested on "large colonies of rabbits." Pharma companies didn't like the rabbit process, either, because it was slow and expensive.

Robots are set to conduct National Security clearance interviews

Advancing a career in the US government might soon require an interview with a computer generated head who wants to know about that time you took ketamine.

Psychologists at the National Center for Credibility Assessment (NCCA) are developing an interview system that uses a responsive on-screen avatar for the first stage of the national security clearance process.

Initial screening for a variety of government jobs currently requires applicants to fill out a form disclosing past drug use, criminal activity, and mental health issues, which is then reviewed during an interview - with a human.

But a recent NCCA study published in the journal Computers and Human Behavior asserts that not only would a computer-generated interviewer be less "time consuming, labor intensive, and costly to the Federal Government," people are actually more likely to admit things to the robot.

The study used US Army basic trainees as volunteer subjects for a mock national security clearance interview. The trainees were not told that the questions would be asked by a robot. After being hooked up to electrodes for cardiographic and electrodermal (heart and skin) responses the volunteers were told that the interview would be with a computer avatar, and were left alone in a chamber with their on-screen interrogator.

The program used for the study was capable of responding to vocal cues and taking multiple conversation paths depending on the subject's answers. The researchers were hoping to leverage the power of presence: the idea that people recognize another sentient being in the environment, and are more responsive as a result.
