Cactus flowers have a striking range in size—they can be smaller than a grain of rice or longer than a school ruler. Such variation points to how God designed living things with room to adapt while also placing limits on what they can become.
A recent Biology Letters study reports that cactus groups with faster-changing flowers tend to form new species faster.1 Jamie Thompson and Chris Venditti studied flo... More...
Can a freezer make life? A recent paper in Chemical Science suggests that freezing and thawing may have helped early “protocells” grow, merge, and trap DNA.1 But the key issue is not whether ice can move molecules around—it’s whether blind physical cycles can build the coded, regulated systems life requires. The evidence shows that ice can sort preexisting parts, but it cannot engineer life.
Two of Jupiter’s four Galilean moons, Io and Ganymede, were recently featured in science news stories—stories that remind us that these moons are problematic for those who believe the solar system is billions of years old.1,2
The four largest of Jupiter’s more than 100 moons are called the Galilean moons, in honor of their discovery by Galileo Galilei. In order of increasing distance from Jupiter, the... More...
A new species of what appears to be a fossil centipede was found in sediments that conventional scientists believe were deposited offshore.1 The problem for them is that the creature had legs for walking on dry land, leaving them to wonder why these animals evolved terrestrial-style “legs while still living underwater.”2
The new fossil, Waukartus muscularis, was found in Wisconsin’s ... More...
Saturn is famous for its beautiful rings, which are composed mostly of water ice particles. A team of scientists recently proposed that the rings were formed from the breakup of a hypothetical moon about 100 million years ago, a moon they have dubbed Chrysalis.1
Because the force of gravity between two objects rapidly increases as the objects move closer together, a planet’s gravity pulls on the near side of a mo... More...
