American leadership in technology innovation and economic competitiveness is at risk if U.S. policymakers don’t take crucial steps to protect the country’s digital future.
A building’s primary purpose may be to keep the weather out, but most do such an effective job of this that they also inadvertently deprive us of contact with two key requirements for our well-being and effectiveness: nature and change.
Researchers have developed a new kind of semiconductor alloy capable of capturing the near-infrared light located on the edge of the visible light spectrum.
Earth’s climate is changing rapidly. We know this from billions of observations, documented in thousands of journal papers and texts and summarized every few years by the United Nations’ Intergovernmental Panel on Climate Change.
Scientists have found a way to wirelessly transmit electricity to a nearby moving object.
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.
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”?
Misinformation is on the rise. Whatever else one might conclude about self-government, it’s at risk when citizens don’t know something but think they know it. They’ll have opinions, but the opinions will be grounded in something more fanciful than real.
The explosive spread of Zika throughout the Americas is raising questions about the best ways to control this and future epidemics. We first need to identify what factors contribute to the spread of Zika and understand where and when they occur. With that knowledge we can effectively target our resources to fight the disease and control its spread.
There’s a good reason to connected to the electricity distribution network. Anything that can help cut our electricity bill is to be welcomed, and Tesla’s solar rechargeable batteries, now available in Australia, are just the latest option.
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...
Massive bodies can send ripples through space time in the form of gravitational waves.
One hundred years ago, Albert Einstein published his general theory of relativity, which described how gravity warps and distorts space-time.
While this theory
Computer simulation of two merging black holes producing gravitational waves. Scientists working at the LIGO experiment in the US have for the first time detected elusive ripples in the fabric of space and time known as gravitational waves. There is no doubt that the finding is one of the most groundbreaking physics discoveries of the past 100 years. But what are
What happens when LIGO texts you to say it's detected one of Einstein's predicted gravitational waves
Oh hey, I heard ripples in space and time, generated as two black holes merged. Call me back.
The best thing about a day in my life on the lookout for gravitational waves is that I never know when it will begin.
Like many of my colleagues working for the Laser Interferometer Gravitational-Wave Observatory (LIGO), the morning of Monday,...
When two black holes collide, the resulting gravitational ripples can be felt across the cosmos. Up until now, humanity has been deaf to the gravitational “sounds” of the universe. At last, we have heard our first message. On September 14, 2015,
Binary black holes come in a variety of forms, but they are all astounding. It has long been predicted that when two black holes merge, they ought to give out a staggering amount of energy in the form of gravitational waves.
Two black holes collide. One hundred years ago Albert Einstein in his general theory of relativity predicted the existence of a dark side to the cosmos. He thought there were invisible “gravitational waves”, ripples in space-time produced by some of the most violent events in the cosmos – exploding stars, colliding black holes, perhaps even the Big Bang itself. For decades,
The battle of Voltage Pictures vs illegal downloaders of the Dallas Buyers Club was always going to set a precedent for the movie industry and the Australian market. If Voltage had prevailed in the courts, downloaders faced
I think it’s fair to say that I am fairly experienced in dealing with excrement. While some of this comes with caring for two small children, most of my faecal-awareness comes from first career as a veterinarian. In veterinary practice, the characteristics

The 4km long arms of the LIGO experiment at Hanford. Gravitational waves are mysterious ripples in the fabric of space and time that travel across our universe at the speed of light. Predicted by Einstein exactly 100 years ago, a number of experiments have been searching for them. One of these experiments, LIGO, has now found them.
Remove your rose-colored glasses and take a cold, hard look at your potential Valentine. “Will you be my Valentine?”People all across the country say those words in the run-up to February 14 and the Valentine’s Day holiday. Whether
Plenty more needs doing to help plug the gender gap in science.The first United Nations International Day of Women and Girls in Science is being celebrated today, with a number of articles profiling women scientists...
A few genetic tweaks can solve a lot of problems. In a world with a ballooning population and deteriorating environment, we will need to use every trick in the book to stave off mass starvation, disease and political chaos.
With moralistic gods watching, it’s easier to be fair and cooperative.For the bulk of our evolutionary history, human groups were small, tightly knit communities. Only quite recently, some human groups started evolving into the large-scale societies..
Imagine it’s Valentine’s Day and you’re sitting in a restaurant across the table from your significant other, about to start a romantic dinner.
As you gaze into each other’s eyes, you wonder how it can possibly be true that as well
The aftermath of the German collision which is now under investigation.
Whenever we hear of an accident such as the head on train collision that occurred in Bavaria on Tuesday our first thoughts must be with the victims
Drone on the loose.
Reckless or criminal uses of drones are on the rise and police forces have reported “a spike” in the number of drone-related incidents in the UK, mirroring the growth in the technology’s popularity. This ranges
Superconductors enable vehicles like this maglev train in Shanghai to move without touching the ground.
One of the most remarkable and unexpected discoveries of the 20th century is that some materials can become “superconductors“ when cooled down to very
