A new organization called the Association for Mathematical Research (AMR) has ignited fierce debates in the math research and education communities since it was launched last October. Its stated mission is “to support mathematical research and scholarship”—a goal similar to that proclaimed by two long-standing groups: the American Mathematical Society (AMS) and the Mathematical Association… Continue reading New Math Research Group Reflects a Schism in the Field

To health care workers in the COVID era, holidays mean death, and we knew Omicron was coming before it had a name. The wave caused by this variant has barely begun, rapidly gathering steam, and we are exhausted, attempting to pull from reserves badly drained by earlier surges. Back in August, the beds of my… Continue reading Nurses Struggle through a New COVID Wave with Rage and Compassion

Humans are very good at inventing commodities, and we’ve been at it for a long time. See that pebble over there? Well, that’s a better pebble than all these others, and if you give me something in exchange for it, I’ll let you take ownership. It’ll be your pebble, forever. And soon there will be… Continue reading The Worrisome Rise of NFTs

As quantum computers have become more functional, our understanding of them has remained muddled. Work by a pair of computer scientists has clarified part of the picture, providing insight into what can be computed with these futuristic machines. “It’s a really nice result that has implications for quantum computation,” said John Watrous of the University… Continue reading Computer Scientists Eliminate Pesky Quantum Computations

Every January nearly half of Americans make New Year’s resolutions. We resolve to eat better, exercise more, get organized, spend less money, and so on. Unfortunately, several studies suggest that most of these resolutions don’t stick. But it doesn’t have to be that way. If you’ve made a resolution this year and would like help… Continue reading New Year’s Resolutions Are Notoriously Slippery, but Science Can Help You Keep Them

Bush fire season is underway again in Australia, where summer has just kicked off. Yet the country is still recovering from record-breaking wildfires two years ago that killed at least 33 people, destroyed thousands of homes and burned more than 65,000 square miles of land. How quickly the natural landscape recovers depends on the climate… Continue reading Fires Doubled Australia’s Carbon Emissions—Ecosystems May Never Soak It Back Up

I sometimes worry that many who would enjoy a scientific career are put off by a narrow and outdated conception of what’s involved. The word “scientist” still conjures up an unworldly image of an Einstein lookalike (male and elderly) or else a youthful geek. There’s still too little racial and gender diversity among scientists. But… Continue reading Lessons for a Young Scientist

Doctors have transplanted the heart from a genetically modified pig into the chest of a man from Maryland in a last-ditch effort to save his life. The first-of-its-kind surgery is being hailed as a major step forward in the decades-long effort to successfully transplant animal organs into humans.  Although it’s been tried before—one of the… Continue reading Surgeons Transplant Pig’s Heart into Dying Human Patient in a First

Richard Leakey, paleoanthropologist, conservationist and Kenyan political leader, died January 2 at his home near Nairobi. His expeditions discovered hundreds of hominin fossils, leading Fred Spoor, a paleontologist at the Natural History Museum in London, to tell me his findings were “a most extensive and diverse fossil record of early human evolution.”* Other scientists, conservationists,… Continue reading Richard Leakey’s Legacy in Science, Conservation and Politics

Explore It’s 2050. The world population has increased by 2.3 billion to 9.9 billion. Demand for food has risen 70 to 100 percent but a warming planet, extreme weather, and a decrease in arable land is threatening food security. Luckily, farmers can grow crops more densely, increasing yield from smaller plots of available agricultural land.… Continue reading Plants Fight for Their Lives
