How tiny phytoplankton trek long distances upward in the ocean
Taking in seawater while filtering out dense salts lets unicellular phytoplankton migrate tens of meters vertically toward sunnier seas.
Here are some stellar picks from Nikon’s top microscopy images of 2024
The annual Small World photomicrography competition, now in its 50th year, puts life’s smallest details under the microscope.
Here’s why being creative is good for your brain
Neuroarts, a new field of science, is finding that exposure to arts can improve learning, behavior and mental health.
The cataclysmic origins of most of Earth’s meteorites have been found
Just a few smashups in the asteroid belt may account for 70 percent of Earth’s meteorites, limiting what’s known about our solar system’s history.
Carnivorous plants eat faster with a fungal friend
Insects stuck in sundew plants’ sticky secretions suffocate and die before being subjected to a medley of digestive enzymes.
Experiment: Make your own craters!
Let’s make our own craters in cocoa and flour to learn how these features form throughout the solar system — and why they’re different sizes.
NASA’s Europa mission is a homecoming for one planetary astronomer
Over her long career, Bonnie Buratti has seen the search for life in the solar system go from a joke to a flagship mission.
At-home experiments shed light on cats’ liquid behavior
Cats can flow like liquids through tall crevices, but they solidify a bit as they approach short crannies, new research shows.
Weird? These bat toes can glow greenish-blue
Hairy bristles on the toes of Mexican free-tailed bats fluoresce under UV light. The reason is a mystery.

Underwater mountains in the Pacific Ocean may be home to 20 new species
A recent expedition to undersea mountain ranges off the coast of Chile revealed a new seamount and a rich world of deep-sea biodiversity.
Navigation research often excludes the environment. That’s starting to change
Participants “navigating” on a lab computer have shaped navigation knowledge. Studies that add in the environment challenge those findings.
Saturn’s first Trojan asteroid has finally been discovered
Saturn joins the sun’s other giant planets that have Trojans, space rocks that orbit along the same path.
DNA from old hair helps confirm the macabre diet of two 19th century lions
Genetic analysis of cavity crud from two famed man-eating lions suggests the method could re-create diets of predators that lived thousands of years ago.
Radioactive beams give a real-time view of cancer treatment in mice
This first successful treatment of tumors with radioactive ion beams could one day lead to treating human patients’ tumors with millimeter precision.
Scientists want to create a sort of Noah’s Ark on the moon
Climate change is threatening Earth’s biodiversity banks. A lunar “ark” would safeguard seeds and cells against changes happening on Earth.
Hair pulling prompts one of the fastest known pain signals
The ouch of hair pulling is transmitted with the help of a protein used to sense light touches. These details could lead to new treatments.
A viral gene drive could offer a new approach to fighting herpes
A new gene drive can copy and paste itself into the genomes of herpes simplex viruses in mice. The end goal is a version that disables the virus in humans.
There’s a new term for attempting to own the wind: ventography
Nations established territorial claims underground to access oil and gas. Now they are expanding those claims upward to snag the wind.
What leads rivers to suddenly change course?
An analysis of satellite data could help predict where rivers will change their course and where their rerouted flows will go.
