In fact, in many countries, the internet, the very thing that was supposed to smash down the walls of authoritarianism like a sledgehammer of liberty, has been instead been co-opted by those very regimes in order to push their own agendas while crushing dissent and opposition. And with the emergence of conversational AI -- the technology at the heart of services like Google's Allo and Jigsaw or Intel's Hack Harassment initiative -- these governments could have a new tool to further censor their citizens. Turkey, Brazil, Egypt, India and Uganda have all shut off internet access when politically beneficial to their ruling parties. Nations like Singapore, Russia and China all exert outsized control over the structure and function of their national networks, often relying on a mix of political, technical and social schemes to control the flow of information within their digital borders. The effects of these policies are self-evident.

Stealth bombers and armed drones launched airstrikes Wednesday night against two Islamic State encampments in northern Libya in an expansion of the air war there, according to the Pentagon. The attacks were authorized by President Obama two days before he leaves office and are a reminder of the continuing turmoil in the oil-rich nation where a U.S.-led air war helped insurgents overthrow strongman Moammar Kadafi in 2011. Islamic State militants in Libya have established what officials say is the group's largest and most powerful affiliate outside its core areas in Syria and Iraq, although its area of control has shrunk considerably over the last year. B-2 bombers targeted two desert camps about 30 miles southwest of Surt, a port city on the central Mediterranean coast that U.S.-backed Libyan forces recaptured last year from the militants. U.S. officials said dozens of militants had escaped from Surt to the desert camps.

An orangutan has been captured performing DIY better than some humans. The incredible new footage reveals a female great ape using a saw to skilfully divide a branch in two. The talented ape uses her right hand to hold the tool and her feet to grip the tree branch like a vice. She even blows away the sawdust to inspect her work like a true craftsman. An orangutan has been captured performing DIY better than some humans.

January 18, 2017 --Barren circles dot the dry grasslands across about 1,500 miles of the Namib Desert stretching down the southwestern coast of Africa, emerging, growing, shrinking, and disappearing in lifetimes of 30 to 60 years. The empty patches are accentuated by a rim of particularly tall grasses that ring the circles, which range from 6 feet to 115 feet wide. The fairy circles, as the strange bare soil spots are called, have long puzzled scientists. Although they look a bit like imprints left by massive raindrops, impacting meteors, or as legend would have it, the feet of gods, researchers suspect the pattern may form as a result of a more systematic natural process. But just what that process might be has been the subject of much debate.

The word "drone", a short term for an unmanned aerial vehicle, usually conjures up images of a menacing machine that spies and shoots from on high. However, over the past three years, a new generation of drones has emerged to address civilian and humanitarian needs, from surveying disaster zones to delivering aid. In the future, friendly drones could even whisk commuters above congested streets or haul cargo across Africa – if a desperate lack of legislation is addressed. Rapid progress in two key technological areas lies behind this new wave of friendly drones. On the one hand, essential parts including batteries and sensors have become smaller and cheaper, largely because of progress in commercial electronic devices.

From the nature of the cosmos to the nature of societies, the following 100 questions span the sciences. Some are pieces of questions discussed above; others are big questions in their own right. Some will drive scientific inquiry for the next century; others may soon be answered. Many will undoubtedly spawn new questions. A number of quantum theorists and cosmologists are trying to figure out whether our universe is part of a bigger "multiverse." But others suspect that this hard-to-test idea may be a question for philosophers. In the first moments after the big bang, the universe blew up at an incredible rate. But what did the blowing? Measurements of the cosmic microwave background and other astrophysical observations are narrowing the possibilities. When and how did the first stars and galaxies form? The broad brush strokes are visible, but the fine details aren't.

Two rhinos at the Kuzikus Nature Reserve in Namibia, photographed by drone. When the U.S. military needed to identify mines in a dangerous valley in Afghanistan, aerial-imagery specialist Tudor Thomas helped build a plane-based system to map it. Back in 2013, similar systems cost the military and its contractors one to five million dollars, Thomas says--and that didn't even include the cost of the plane. "It's hard to comprehend how much was getting spent just to make a simple aerial image," he says. The experience sparked an idea for a business: mapping by drone.

Meier's open-source software is constantly evolving as it is applied in different contexts. For example, it was used to create maps showing population displacement during the humanitarian crisis in Libya. Natural disasters and political unrest trigger torrents of tweets and posts--chaotic snippets of what could be valuable information. Patrick Meier, director of social innovation at the Qatar Computing Research Institute, applies artificial intelligence to this crowdsourced data, organizing digital photos and messages into dynamic maps that can guide real-world relief efforts. Popular Science:__ You work in crisis mapping--what is that exactly?

Fraud punished A Parkinson's disease researcher in Australia pleaded guilty to research fraud and was handed a two-year suspended prison sentence by a court in Brisbane on 31 March. Bruce Murdoch, formerly of the University of Queensland in Brisbane, was found to have falsified results published in the European Journal of Neurology in 2011; three of his papers have been retracted. In a statement to the blog Retraction Watch, University of Queensland vice-chancellor Peter Høj said that the university had reimbursed around Aus$175,000 (US$132,000) to funding bodies associated with Murdoch's work. Ice wall to stem Fukushima leak The Tokyo Electric Power Company (TEPCO) on 31 March began freezing the soil surrounding reactors 1 to 4 of the disaster-stricken Fukushima Daiichi nuclear power plant. A refrigeration system (pictured) is creating a 30-metre deep, 1.5-kilometre-long wall of frozen ground that aims to stop groundwater from flowing under the plant and carrying radioactive isotopes into the sea.

Born in South Africa, he was educated at the South African College High School, took a first degree at the University of Cape Town in 1934 and a doctorate in Mathematical Physics at the University of London in 1953. After a spell as demonstrator in physics at Cape Town, he emigrated to Britain. Prior to the outbreak of the Second World War, he undertook ionospheric research in Marconi's Wireless Telegraph Company, transferring to the Government's Telecommunications Research Establishment after the outbreak of hostilities to carry out research on radar. In 1941, he enlisted in the Royal Air Force Volunteer Reserve, leaving in 1943 to go to Aberdeen University to run a special degree course for radio officers under the wartime Hankey Scheme. After the war was over, he returned to industrial research, first until 1949 in Mullard's Radio Valve Company on microwave electronics and then on television and photo-electric tubes at EMI's Research Laboratories.
