The first is simply size. Flight imposes strict weight limits, so birds pack enormous numbers of very small neurons into very small brains. Their axons, the long cable-like fibers that transmit electrical and chemical signals between cells, are shorter. “Long lines take time. Short lines speed everything up,” Nieder said. The second factor is temperature. ..

A 25-year-old German experimental photographer has won the 2026 Nikon Small World photomicrography competition with a striking image of droplets of ink being deposited on paper by an inkjet printer. Ole Bielfeldt beat out 1,802 other entries hailing from 69 different countries. Bielfeldt became interested in photomicrography during the COVID-19 lockdown after discovering an old ..
To tap meetings for study, researchers typically use two approaches. The first is a classic survey in which researchers retroactively ask people about their real or simulated meeting experiences and analyze the responses. The second method is to analyze specific behaviors and trends extracted from audio and video recordings of meetings. Such precise content is ..
The Liberty Bell, with its famous crack, hasn’t been rung in 180 years, but that hasn’t stopped scientists from pondering what the bell might have sounded like when tolling. In honor of the nation’s 250th anniversary, researchers at Penn State University have modeled its acoustic properties, drawing on data collected from one of the bell’s ..
One reason plastics are used so often is that they’re chemically inert, meaning bags, food containers, and cups don’t react with what we put in them. Yet they can still break down into microplastics, which turn up in drinking water, human blood, arteries, and brains. The consequences of that are uncertain. “Whether microplastics can directly ..
Rocket Lab announced Wednesday that its Neutron launch vehicle won’t fly until 2027, citing an issue discovered during manufacturing of the rocket’s carbon composite structures. The announcement was public confirmation of what nearly everyone inside Rocket Lab and the wider space industry already knew. The most recent official update from Rocket Lab in August suggested ..
When it comes to deciding the fate of the planet, Colleen Golja always thought science and reason would have a seat at the table. That was until one morning last September in London, when the climate researcher took part in the first in a series of war games. The goal: to prevent an uncontrolled global ..
Credit: Nguyen Nam Nhat. Last month we covered the winner of Nikon’s Small World in Motion video: Ning Xu of Tsinghua University in China, whose video captured tiny cilia beating in the airways of a child with a rare respiratory disorder. But allegations surfaced about Xu’s use of AI while making the video. Nikon launched ..
Hamilton would often bring her 4-year-old daughter, Lauren, to the lab on nights and weekends. The child loved pretending to be an astronaut in the simulators, and one day her random button-pressing caused the system to inexplicably crash. Apparently Lauren had typed “P01,” a pre-launch sequence, in the middle of the mission. Hamilton asked NASA ..
About 66 million years ago, the Chicxulub asteroid smashed into Earth, kicking up tsunamis and dropping hot debris that annihilated non-avian dinosaurs and many other species. But not everything it left in its wake was destructive. This space rock hit what is now the partially submerged Yucatan Peninsula, and at the bottom of the ocean, ..
