Hybrid Pythons Are Winning The Invasive Snake War In Florida Everglades

Interspecies breeding is creating a slippery problem in Florida’s conflict with invasive pythons. A few years ago, scientists discovered that a significant number of the giant snakes stalking the Everglades are hybrids created as a result of breeding between two different species. Remarkably, these hybrids appear to be even better-adapted to this new environment than their separate parent species. Read the full story here


The Observable Universe Might Be A Black Hole, Suggests A Chart Of Everything

It seems such a simple idea it’s surprising no one has done it before: plot everything from subatomic particles to superclusters on a chart of mass and radius. Now that someone has, the results raise some very intriguing, and possibly a little disturbing, questions. Read the full story here

Adults With ADHD Could Be Up To 3 Times More Likely To Develop Dementia

Adults with attention deficit hyperactivity disorder (ADHD) are almost three times more likely to develop dementia than those without the condition, according to a new study. It highlights the need for more attention to be paid to a group that has historically been excluded from this kind of research. Read the full story here

Pepper X Is Crowned World’s Hottest Chili By Guinness World Records

Measuring in at a tongue-blistering 2,693,000 Scoville Heat Units (SHU), “Pepper X” has been awarded the title of the world’s hottest chili pepper. It dethrones the infamous Carolina Reaper chili, which averages at a comparatively mild 1.64 million SHU. Someone pass the milk. Read the full story here

Molecules Crucial For Life Formed In Water On Dwarf Planet Ceres

Ceres is the only dwarf planet in the inner Solar System and it was visited by the Dawn mission last decade. NASA’s spacecraft revealed that the world hosts complex organics, possible volcanism where salt erupted, and plenty of water ice. The origin of organics was not fully understood: were they native to Ceres or were they brought by carbon-rich asteroids? Read the full story here

Whaling Was Once A Big Industry In The US, But It Wasn't Meat They Were After

At its peak, whaling was the fifth-biggest industry in the US and the animal was almost hunted to extinction in the 19th century; however, this multi-million-dollar industry was not driven by demand for meat, but by a strange commodity that became integral to the Industrial Revolution.
