We summarize the week's scientific breakthroughs every Thursday.
- Neuroscience
50 years ago, scientists were on the trail of ‘memory molecules’
In the 1970s, scientists found the first “memory molecule.” Several other candidates have popped up in the decades since.
- Neuroscience
Brainless sponges contain early echoes of a nervous system
Simple sponges contain cells that appear to send signals to digestive chambers, a communication system that offer hints about how brains evolved.
- Animals
Baleen whales eat (and poop) a lot more than we realized
The sheer volume of food that some whales eat and then excrete suggests the animals shape ecosystems to a much larger degree than previously thought.
- Microbes
Are viruses alive, not alive or something in between? And why does it matter?
The way we talk about viruses can shift scientific research and our understanding of evolution.

Gene-edited stem cells help geckos regrow more perfect tails
Regenerated gecko tails are a far cry from perfect. Now experiments have coaxed geckos to regrow better ones with nerve tissue and bonelike cartilage.
- Math
An elusive equation describing bird eggs of all shapes has been found at last
A new mathematical equation describes bird eggs of all shapes found in nature, and it could have applications in food and agricultural research.
- Animals
Assassin bugs tap spiders to distract them before a lethal strike
Some assassin bugs stroke their antennae on spiders when within striking distance, possibly imitating touches that spiders experience near their kin.
- Humans
Ancient human visitors complicate the Falkland Islands wolf’s origin story
Scientists have debated how the Falkland Islands’ only land mammal journeyed to the region: by a long-ago land bridge or with people.
- Genetics
DNA from mysterious Asian mummies reveals their surprising ancestry
Ancient DNA indicates that an enigmatic Bronze Age group consisted of genetic, but not cultural, loners.
- Animals
Flamingos dye their sun-faded feathers to stay pretty in pink
During mating season, flamingos rub a makeup-like rouge on their necks to catch the eye of the opposite sex. They don’t bother once chicks are born.
- Animals
Jumping spiders’ remarkable senses capture a world beyond our perception
Clever experiments and new technology are taking scientists deep into the lives of jumping spiders, and opening a portal to their experience of the world.

How these sea-loving mangroves ended up far from the coast
On the Yucatán Peninsula, mangroves trapped nearly 200 kilometers from the ocean are part of a “relict ecosystem” that’s more than 100,000 years old.
