MILAN – Despite China’s widely discussed economic slowdown, annual GDP growth remains above 7%, implying little cause for alarm – at least for now. The question is whether the government’s […]
Oslo to Copenhagen, the world’s next megacity?
The greatest cosmic battle — between gravity and expansion — has been going on for billions of years. Who will win? “We can lick gravity, but sometimes the paperwork is overwhelming.”-Wernher von Braun When you […]
The Sun — like nearly all stars — burns bright through its nuclear reactions, sending light, heat and energy out into the Universe over a timespan of billions of years. But how? “The sun is […]
It’s a huge surprise, and shows up in the most unlikely of places! “You cannot, in human experience, rush into the light. You have to go through the twilight into the […]
On July 4, 2012 a team of physicists in Switzerland announced one of the biggest discoveries in science: the Higgs boson–the “God particle” that could explain why all matter has […]
A Dutch designer wants to take the elements that make jellyfish glow and apply them to trees. Daan Roosegaarde envisions trees serving as streetlights one day. With the help of […]
Look up after sunset for the most reliable meteor shower of the year: the Perseids, and learn where they come from! Image credit: Michael Menefee (Fort Photo on flickr), via […]
And if not, how do you reason with those who believe they are? “Ignorance is hardly unusual, Miss Davar. The longer I live, the more I come to realize that […]
An animal becomes so much more the instant you first love them. Image credit: me, of my first dog, Cordelia, back in 2008. “Dogs are our link to paradise. They […]
If the Universe began with equal amount of matter and antimatter, why does matter dominate today’s cosmos? “You may not feel outstandingly robust, but if you are an average-sized adult you […]
The goal of this blog is to help raise awareness of what I call The Risk Perception Gap the danger that arises when we worry about some things more […]
A few thoughts on your lazy brain. But just a few because, well, you know, the brain likes things nice and easy. The brain normally operates on what […]
The Standard Model can’t be all there is. Here are five compelling reasons why. “Other than the laws of physics, rules have never really worked out for me.” –Craig Ferguson Two […]
Someday, the Sun will expand, engulfing Mercury and Venus, and then some. Will we survive? “They do not see what lies ahead, when Sun has faded and Moon is dead.”-J.R.R. Tolkien […]
From asteroids to planets to stars and more, doubling what you’ve got can be disastrous! “Art has a double face, of expression and illusion, just like science has a double […]
Now that spring is here, people want to start getting into better shape for the summer. Eating healthier will help you feel more energetic and boost your brain power, too. […]
What researchers are calling “cosmology’s missing link” has been detected, providing a “smoking gun” for the Big Bang Theory. Discovery reports: For the first time, scientists have found direct evidence […]
It’s easier than you might think, and we’ve been doing it for over a century. “The doctors realized in retrospect that even though most of these dead had also suffered from […]
The less we know about something like energy, the more likely we are to use and abuse it in ways with long-reaching, harmful consequences.
Stephen Hawking has proposed a breakthrough theory in a new paper – the idea that black holes can exist without an event horizon.
The auroras appear mostly green, as high energy particles hitting the Earth’s atmosphere cause the air to glow as electrons resettle into their oxygen hosts.
Is running up an inclined treadmill the same, physically, as running up an actual mountain? Here’s what science has to say. “Nothing worth having was ever achieved without effort.” -Teddy Roosevelt […]
It’s known as the Mpemba effect, and it’s been observed as far back as Aristotle. But hot water really can sometimes freeze faster than cold, and the science of why […]
Editor’s Note: This article was provided by our partner, RealClearScience. The original is here. IN 1939, INTREPID engineers at the fledgling British Interplanetary Society proposed a daring mission into outer […]
When we look across the Universe, we find that things used to be closer together in the past. So how large do things appear when they’re very far away? “Life is […]
How our best physical understanding of the early stages of the Universe — that set up the hot Big Bang — inevitably leads us to conclude that there’s a lot more than what’s merely […]
How do we know how old the most distant objects we see actually are? “Sometimes a person has to go a very long distance out of his way to come back […]
Alan Alda recently challenged scientists to explain this simple question to 11-year-olds in less than 300 words. Could you do it? “You can’t get there by bus, only by hard work […]
