How Do You Know If A Feathered Dinosaur Could Fly? Not all birds can fly. Penguins, ostriches, and kiwis are some famous examples. It’s pretty easy to figure out if a living bird can fly. But it’s a bit tricker when it comes to extinct birds or bird ancestors, like dinosaurs. Remember, all birds are dinosaurs, but not all dinosaurs evolved into bir…

Climate scientist Dr. Michael Mann won a defamation lawsuit against two conservative writers last week. The verdict was 12 years in the making. In 2012 writers Rand Simberg and Mark Steyn accused Mann of manipulating his data related to his famous 1998 “hockey stick” graph, which depicts rising global temperatures after the industrial revolution. S…

Over the past few years, many cities around the world have changed dramatically as a result of the COVID-19 pandemic, with shifts in office use and commuting patterns as well as where people choose to live, work, and play. But there are other major changes to communities on the horizon as well—such as the need to adapt to the changing climate and s…

Looking into space can be pretty daunting. How do we make sense of the vast expanse above our heads, the millions of stars we might be able to see, and the billions more we can’t? Now, what about listening to space? That’s the task that Sam Harnett and Chris Hoff gave themselves, for their series “Cosmic Visions.” They’re the team behind “The World…

Colorectal Cancer Rates Are Rising In Young People Gastrointestinal medicine practitioners have noticed something strange in recent years: More and more young people are being diagnosed with colorectal cancer. It used to be incredibly rare for anyone under the age of 50 to be diagnosed with colorectal cancer. Cases were generally limited to people …

Uché Blackstock always knew she wanted to be a doctor. Her mother was a physician at Kings County Hospital in Brooklyn, New York. Uché and her twin sister, Oni, would often visit their mother at work, watching her take care of patients. And they loved to play with their mother’s doctor’s bag. The sisters went on to become the first Black mother-dau…

Hycean planets were thought to be covered by oceans of water, but a new study suggests it could be magma instead. And, author Rafi Kohan explains the psychological and physiological responses to trash talk, ahead of Super Bowl Sunday. Faraway Planets Could Have Oceans Of Magma Far beyond our solar system are hycean planets—planets that have hydroge…

A new study uses artificial intelligence to show that each of our ten fingerprints are remarkably similar to one another. Plus, honey could be the secret ingredient in building a more eco-friendly “memristor,” which transmits data through malleable pathways. Is Each Fingerprint On Your Hand Unique? We often think about each fingerprint as being com…

Last month the FDA approved a new treatment for sickle cell disease, the first medical therapy to use CRISPR gene editing technology. It works by identifying the gene or genes causing the disorder, modifying those genes and then returning them to the patient’s body. There are now two gene therapies offered by pharmaceutical companies for sickle cel…

A team of scientists in Ecuador is on a mission to describe new-to-science tarantula species to help secure conservation protections. And, undergraduate researchers pasted striped capes onto termites’ backs to see if a well-known warning sign would fend off predators.

Cancer, at its core, is a genetic disease: the result of DNA mutations that cause cells to grow out of control and develop tumors. And over the years, scientists have identified certain chemicals, called carcinogens, that are directly linked to those cancer-causing mutations, like those found in cigarettes. But the rates of some cancers, like color…

There has been a boom of syphilis cases, including a 180% increase in congenital syphilis cases, despite other STI levels staying stable. Also, the world's largest deep-sea reef stretches for hundreds of miles in near-freezing waters and total darkness, but it’s bustling with life. Syphilis Cases Are Up 80% Since 2018 Syphilis is rearing its ugly h…
