Intuition tells mathematicians that adding 2 to a number should completely change its multiplicative structure — meaning there should be no correlation between whether a number is prime (a multiplicative property) and whether the number two units away is prime (an additive property). Number theorists have found no evidence to suggest that such a correlation… Continue reading Mathematicians Outwit Hidden Number Conspiracy

An Injection of Chaos Solves Decades-Old Fluid Mystery
Fluids can be roughly divided into two categories: regular ones and weird ones. Regular ones, like water and alcohol, act more or less as expected when pumped through pipes or stirred with a spoon. Lurking among the weird ones — which include substances such as paint, honey, mucus, blood, ketchup and oobleck — are a… Continue reading An Injection of Chaos Solves Decades-Old Fluid Mystery
Epstein-Barr Virus Found to Trigger Multiple Sclerosis
A connection between the human herpesvirus Epstein-Barr and multiple sclerosis (MS) has long been suspected but has been difficult to prove. Epstein-Barr virus (EBV) is the primary cause of mononucleosis and is so common that 95 percent of adults carry it. Unlike Epstein-Barr, MS, a devastating demyelinating disease of the central nervous system, is relatively… Continue reading Epstein-Barr Virus Found to Trigger Multiple Sclerosis
Plants are Stuck as Seed-Eating Animals Decline
As Earth heats up from the burning of fossil fuels, the climate conditions that species have adapted to are increasingly shifting away from their historical ranges. But while birds and other animals can often fly, walk or swim to follow their preferred environment, plants are quite literally rooted to the ground. They require outside forces… Continue reading Plants are Stuck as Seed-Eating Animals Decline
What’s Holding Up New Omicron Vaccines?
All the vaccines we use to ward off SARS-CoV-2, the virus that causes COVID, share one crucial feature: they were designed to protect against its ancestral form, which surfaced in Wuhan, China, more than two years ago. Today’s virus, however, is not the same as it once was. SARS-CoV-2 has been evolving, with successive variants… Continue reading What’s Holding Up New Omicron Vaccines?
We Are Beast Machines – Issue 111: Spotlight
I have a childhood memory of looking in the bathroom mirror, and for the first time realizing that my experience at that precise moment—the experience of being me—would at some point come to an end, and that “I” would die. I must have been about 8 or 9 years old, and like all early memories… Continue reading We Are Beast Machines – Issue 111: Spotlight
How Targeted Advertising on Social Media Drives People to Extremes
The following essay is reprinted with permission from The Conversation, an online publication covering the latest research. Have you had the experience of looking at some product online and then seeing ads for it all over your social media feed? Far from coincidence, these instances of eerily accurate advertising provide glimpses into the behind-the-scenes mechanisms… Continue reading How Targeted Advertising on Social Media Drives People to Extremes
It’s Time for a Global Ban on Destructive Antisatellite Testing
In November, Russia ignited an international uproar with a weapon test that launched an interceptor against a defunct military satellite. When it hit, that deliberate collision shattered the satellite into more than 1,500 trackable pieces of debris. This space debris is dangerous; it could hit and severely damage an orbiting space station, akin to the… Continue reading It’s Time for a Global Ban on Destructive Antisatellite Testing
Solar Power Could Boom in 2022, Depending on Supply Chains
2022 is shaping up to be a solar boom. That is, if supply chain constraints don’t undercut the industry. The U.S. Energy Information Administration projects U.S. solar companies will install 21.5 gigawatts of utility-scale capacity this year, shattering the annual record of 15.5 GW set last year. But EIA’s projection comes amid a period of considerable uncertainty… Continue reading Solar Power Could Boom in 2022, Depending on Supply Chains
If Aliens Exist, Here’s How We’ll Find Them – Issue 111: Spotlight
Suppose aliens existed, and imagine that some of them had been watching our planet for its entire four and a half billion years. What would they have seen? Over most of that vast timespan, Earth’s appearance altered slowly and gradually. Continents drifted; ice cover waxed and waned; successive species emerged, evolved, with many of them… Continue reading If Aliens Exist, Here’s How We’ll Find Them – Issue 111: Spotlight
