Ebola outbreak in the Democratic Republic of the Congo

The Ebola outbreak in the Democratic Republic of the Congo (DRC) is quickly becoming an international concern. With 489 people diagnosed with the disease and 280 deaths, it is already the second largest Ebola outbreak in history (although still dwarfed by the 2014 West Africa outbreak). While the DRC has a good track record of responding to these outbreaks, the ongoing military conflict in...

Some Eastern European youngsters living in the UK say they feel less welcome since Brexit​

It is hard for me to identify as both British and Romanian because people make me feel as if you can’t be both – as if being foreign is a permanent thing and can’t be changed no matter how long you’ve spent in a country or what you consider to be “home”. I consider the UK to be my home. Like Romanian teenager Ioana,...

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...
