Fiber V2.0 Science of Health Enhancing Benefits
Fiber is so much more than “roughage!” From your heart, to your bones, to your microbiome, the list of health benefits linked to fiber keeps getting longer as nutrition science learns more about what it does for us. THE QUICK NOTES “Soluble versus insoluble” is not the only (or even the most useful) way to sort and categorize fiber. Benefits attributed to fiber include...

Divisions of Islamophobia
A false dichotomy is a basic type of informal logical fallacy, consisting in framing an issue as if there were only two choices available, while in fact a range of nuanced positions may be on offer upon more careful reflection. There are nonetheless plenty of instances were they do identify truly bad reasoning.Another one is arguably represented by the never ending “debate” about Islamophobia....

A Short Guide to Hard Problems
How fundamentally difficult is a problem? That’s the basic task of computer scientists who hope to sort problems into what are called complexity classes. These are groups that contain all the computational problems that require less than some fixed amount of a computational resource — something like time or memory. Take a toy example featuring a large number such as 123,456,789,001. One might ask:...

Finding links between the Standard Model of particle physics and the octonions
In 2014, a graduate student at the University of Waterloo, Canada, named Cohl Furey rented a car and drove six hours south to Pennsylvania State University, eager to talk to a physics professor there named Murat Günaydin. Furey had figured out how to build on a finding of Günaydin’s from 40 years earlier — a largely forgotten result that supported a powerful suspicion about...

It is science alone that can solve the problems of hunger and poverty?
In the early days of independent India, Prime Minister Jawaharlal Nehru said, “It is science alone that can solve the problems of hunger and poverty … of a rich country inhabited by starving people.” Would any head of state today voice this view? A 2013 poll recorded that only 36% of Americans had “a lot” of trust that the information they get from scientists is accurate...

Your body, when stressed
Stress is great. It makes us faster, stronger, more agile and our brains have better recall and flexibility. That’s why people are willing to put themselves in stressful work situations or engage in extreme sports. The problem is that uncontrolled, stress can leave us frozen to the spot and unable to think – something all too familiar for people having to speak in public...

Antidepressants Cause Weight Gain?
Antidepressant medications can be hugely helpful—even life-saving—for those who suffer from certain types of mood disorders. But they can also sometimes cause people to gain a significant amount of weight. Not so helpful. Studies indicate that about 25% of the people who take antidepressant medications report significant weight gain. This is seen more commonly in those who take these drugs for six months or...

Wormhole Allows Information to Escape Black Holes
In 1985, when Carl Sagan was writing the novel Contact, he needed to quickly transport his protagonist Dr. Ellie Arroway from Earth to the star Vega. He had her enter a black hole and exit light-years away, but he didn’t know if this made any sense. The Cornell University astrophysicist and television star consulted his friend Kip Thorne, a black hole expert at the...

How to help Vaccine Doubters
We are in the golden age for vaccines. We have dozens of highly effective vaccines licensed for infectious disease, promising new technologies contributing to massive advancement of vaccine development, and several promising vaccines on the horizon. Unfortunately, vaccines have been a victim of their own success. With the drastic reduction of once-devastating diseases like whooping cough and measles, it seems like some parents think...

Facts on Diet and Inflammation
In health, as with so many things, our greatest strength can be our greatest weakness. Take our astonishingly sophisticated response to injury and infection. Our bodies unleash armies of cellular troops to slaughter invaders and clear out traitors. Their movements are marshaled by signaling chemicals, such as the interleukins, which tell cells where and when to fight and when to stand down. We experience...
