Most of us don't even know what a gram of apple or an ounce of milk looks like, so how can we possibly calculate a sensible portion? Well, perhaps arithmetic is not required, and it may even be misleading.
Evolutionary biologists have news for anyone accustomed to thinking of evolution as a long-term proposition: Evolution also takes place on a day-to-day basis, and it's a tool we must use to keep drug-resistant diseases from spiraling out of control and to prevent mass extinctions.
According to some calculations, there's a 16 percent chance that a significant CME will hit the earth dead center in the next decade. You might want to tell your power company to think about hurrying up with that surge protector and shunt.
We are smart enough. All of us. And we must remain curious and critical lifelong consumers of scientific information, equipped to make informed and responsible decisions that will affect the lives of our neighbors, our environment and ultimately, the whole world.
It sounds like some exotic story that you would find in a National Geographic magazine, but it's actually a story that many physicists are increasingly worried about!
Canadian researchers found that during ovulation the female genitalia is more responsive to images of penetration than to images of oral sex. The difference is significantly reduced during non-fertile phases of the menstrual cycle.
George Church -- professor at Harvard and MIT, multifaceted researcher, entrepreneur, author and advocate of open-access genomics -- gives good quotation. The latest publication to exploit this is The Economist, which just ran a feature about him called "Welcome to my genome," which includes some of Church's predictions for human genetic modification.
Stonehenge was surrounded by a complex of smaller henges and pit-like monuments that appear to have astronomical significance, according to new 3D-scanned maps of the area around the ancient stone circle.
There are problems with the "hardwired" view, and especially with the two lines of research its adherents rely on to stake their claim of fixed, innate gender differences.
Since the 1950s, clinical depression has been thought to be caused by a chemical imbalance in the brain, specifically an imbalance of the neurotransmitter serotonin. But a paper published in ACS Chemical Neuroscience last month suggests that no, depression is not cause by serotonin dysfunction.
It has been over 45 years since the first Moon landing. Neil Armstrong, Buzz Aldrin, and Michael Collins made a journey for the ages as the Apollo 11 mission rocketed humans to another world. But, what have we done lately?
Scientists compared the differences in genes between friends and strangers across nearly 2,000 people and they found that friends tend to have a more similar set of genes than strangers. Perhaps it's "The Starbucks Effect" -- if two people like the smell of coffee maybe they're more likely to hang out together.
For many years, I have been anticipating the start of a revolution in the satellite market, in which the majority of the satellites built and launched would be of the micro, nano, pico, and femto variety.
If it's harder to become a scientist just because you're a girl, imagine how much harder to start on that path as a member of a religious group that's often marginalized by leading scientists in the public sphere.
The Ebola outbreak may also indirectly kill people, by causing a sharp increase in non-Ebola deaths (e.g., deaths due to Malaria, or typhoid fever). Can this "collateral damage" be larger than the recorded death toll, as several reports in the media have suggested?
Imagine how much money could be saved, and how much traffic and pollution could be reduced, if people shared taxis with strangers.
Like most Americans, I grew up on a steady diet of fictional robots. They were occasionally friendly or cooperative, often murderous, typically clumsy and tone-deaf to human emotions and needs
Adolescence begins with puberty and ends, ambiguously, with the makings of adult independence: marriage, financial self-sufficiency, employment.
I think we're headed toward a dystopia that will look for all the world like utopia. We may already have entered this new paradigm and be well on the way toward its irreversibility, which has profound consequences for individual and social action, and for making the best of this moment of transition that may well last centuries.
