The origin of the universe is one of the most difficult realities we ponder.
It bends our logic, straining the words we have to describe it. If one is to say the universe started at the Big Bang some 13.8 billion years ago, the immediate reaction is: "But what came ...

We learned Tuesday that Takaaki Kajita, from the Super-Kamiokande Collaboration in Japan, and Arthur McDonald, from the Sudbury Neutrino Observatory Collaboration in Canada (SNO), won the 2015 Nobel Prize in physics for helping to solve a long-standing mystery in physics: the disappearing neutrinos.
Neutrinos are very weird particles. Proposed ...

On Thursday, the Boston Museum of Science will premiere The Hidden Code at the Charles Hayden Planetarium, a multimedia piece by Paul Miller (aka D J Spooky). The piece combines music, stunning visual effects and live readings to bring science to the general public in ways that only a ...

Few questions of our time are more perplexing than the transition from non-living to living matter.
How did a sample of inorganic chemicals self-organize to become a living creature, capable of absorbing energy from the environment and reproducing? Although the question remains open, there are a few things that we ...

Last week, New York Times science writer George Johnson wrote a very disturbing piece concerning the apparent loss of credibility science is now facing with the public at large.
Creationism, the anti-vaccine movement, resistance to genetically modified crops, cellphone radio waves, fluoridation, the ongoing global climate change debate, the ...

Scanning YouTube for popular science videos, I found a jewel — clocking over 10 million views — titled "Five Experiments That Could Have Destroyed The World."
The fact that we are here means these experiments did not succeed on this front. The message, however, is quite clear: We toy ...

Growing up in Brazil, I always looked up to America and Europe as standards for how to keep cities clean.
Walking along in New York or Paris, I was struck by how the streets and walkways were garbage-free — at least compared to the streets of Rio and São Paulo. ...

Nature is the ultimate puzzle player, as scientists at the European Center for Nuclear Research (CERN) found out last week.
In the late 1950s, particle physics was in crisis. Being the branch of physics that studies the structure of matter, particle physicists search for the smallest bits of stuff ...

It is a remarkable fact that the brain, made of neurons and their connections to one another named synapses, is able to remember.
After all, if there is one thing we can say about our bodies and about nature, it's that change is everywhere. To remember is to go the ...

The age of genetic design is here.
It is now possible to edit genes of diverse organisms — almost like we edit a string of text — by cutting and pasting (splicing) genes at desired locations. A recent technology known as CRISPR (clustered regularly interspaced short palindromic repeats) allows ...

It's hard to have missed the explosive launching of Jurassic World, the new dinosaurs vs. humans bout in Steven Spielberg's venerable series. (This time he is executive producer, while Colin Trevorrow directs.) The movie made history already by being the highest grossing film ever in its first weekend, taking ...
