We often hear about the dark web being linked to terrorist plots, drug deals, knife sales and child pornography, but beyond this it can be hard to fully understand how the dark web works and what it looks like.
Did you know that you actually “see” the world upside down? Well, you do. You just don’t know it because your brain has fiddled around with your perceptions so that you think you see the world right-side up. This is one of many examples of how the brain rethinks what it sees.
China recently launched a satellite into orbit with a unique feature: it has the ability to send information securely, not with mathematical encryption but by using the fundamental laws of physics.
There is a replicability crisis in science – unidentified “false positives” are pervading even our top research journals.
Why do we think that climate sceptics are irrational? A major reason is that almost none of them have any genuine expertise in climate science (most have no scientific expertise at all), yet they’re confident that they know better than the scientists.
An electric car currently relies on a complex interplay of both batteries and supercapacitors to provide the energy it needs to go places. But chemists are developing a new material that could change that.

Mobile phone data may reveal an underlying mathematical connection between how we move and how we communicate. This could make it easier to predict how diseases—and even ideas—spread through a population.
Accidents, natural disasters and random or targeted attacks can cripple human infrastructure. Our transportation networks, supply chains and communication networks are increasing in size and becoming more complex as our populations grow.
"Our theory explains specifically why primates developed superintelligence but dinosaurs—who faced many of the same environmental pressures and had more time to do so—did not. Dinosaurs matured in eggs, so there was no linking between intelligence and infant immaturity at birth," says Celeste Kidd.
It was 1986, and the American space agency, NASA, was reeling from the loss of seven lives. The space shuttle Challenger had broken apart about one minute after its launch.
From the transforming discovery of penicillin to the theories of relativity and quantum mechanics, science progressed with mind-boggling speed even before there were computers. Much of this is down to the robustness of the scientific method: scientific results are validated by being replicated and extended by other scientists.
In the hours since I first sat down to write this piece, my laptop tells me the National Basketball Association has had to deny that it threatened to cancel its 2017 All-Star Game over a new anti-LGBT law in North Carolina – a story repeated by many news sources including the Associated Press.
Ask around – everyone has an opinion about their email and their inbox, and it’s not always positive. From information overload, zero inbox and leaked email scandals to the much-hyped triumph of workflow software like Slack and Asana, email has certainly had a bad rap recently.
Given its huge success in describing the natural world for the past 150 years, the theory of evolution is remarkably misunderstood. In a recent episode of the Australian series of “I’m a Celebrity Get Me Out of Here”, former cricket star Shane Warne questioned the theory – asking “if humans evolved from monkeys, why haven’t today’s monkeys evolved”?
Extra, extra! The embargo’s lifted, read all about it. Rumors were flying through the blogosphere this winter: physicists at the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) may finally have directly detected gravitational waves, ripples in the fabric of space-time predicted by Einstein 100 years ago in his general theory of relativity. Gravitational waves were predicted to be produced by cataclysmic...
Imagine your child requires a life-saving operation. You enter the hospital and are confronted with a stark choice. Do you take the traditional path with human medical staff, including doctors and nurses, where long-term trials have shown a 90% chance that..
Once the three-billion-letter-long human genome was sequenced, we rushed into a new “omics” era of biological research. Scientists are now racing to sequence the genomes (all the genes) or proteomes (all the proteins) of various organisms – and in the process are compiling massive amounts of data.
Any long-term solution will require “decarbonizing” the world energy economy – that is, shifting to power sources that use little or no fossil fuel.
Through pressure from Google, Facebook, and other major providers such as Yahoo and Apple the world wide web is slowing becoming more secure, with web services using HTTPS to encrypt web traffic by default.
