Ancient bird species found in China's Liaoning had extra-long tail feathers for elaborate courtship Sadie Harley Scientific Editor Robert Egan Associate Editor A recently discovered extinct bird from the early Cretaceous Period (approximately 121 million years ago) may have waggled its long tail feathers to attract mates, according to a study published May 27, 2026 in the open-access journal PLOS One by Alexander Clark of the University of Chicago and colleagues. Clark shares more details...
Terahertz biophotonics: Understanding the path towards practical applications for biological imaging
Terahertz biophotonics: Understanding the path towards practical applications for biological imaging Gaby Clark Scientific Editor Alexander Pol Deputy Editor Biophotonics is a multidisciplinary field that involves the development and application of light-based technologies to study, monitor and treat biological systems. The ability to directly image cells and molecules has led to many fundamental discoveries in the past century. More recently, the terahertz (THz) region of the...
'All-in-one' platform developed for multiple trait stacking in crops
'All-in-one' platform developed for multiple trait stacking in crops Gaby Clark Scientific Editor Alexander Pol Deputy Editor A major goal of modern crop breeding is to efficiently combine multiple desirable traits by "stacking" the favorable gene variants (alleles) that contribute to those traits in a single crop variety. However, current strategies are often time-consuming and inefficient. Now, a team led by Gao Caixia at the Institute of Genetics and Developmental Biology of the Chinese...
First steps: America's grueling second spacewalk
First steps: America's grueling second spacewalk Gaby Clark Scientific Editor Alexander Pol Deputy Editor One year after Gemini IV astronaut Edward H. White completed NASA's first spacewalk the agency prepared for a demanding second excursion. Originally scheduled for Gemini VIII, the extravehicular activity (EVA) was reassigned to Gemini IX-A after that mission ended early, with Gene Cernan taking on the task. On June 5, 1966—the mission's third day—Cernan exited the spacecraft and quickly...
A new strategy for assembling π-conjugated panels into square molecules revealed
A new strategy for assembling π-conjugated panels into square molecules revealed Gaby Clark Scientific Editor Alexander Pol Deputy Editor A research group has developed a new method for selectively synthesizing three-dimensional macrocycles,⁽¹⁾ in which four panels are arranged in a square, by connecting planar π-conjugated molecules⁽²⁾ at right angles. This method is applicable to a wide variety of π-conjugated molecules and allows the size of the internal cavity to be designed....
'Flawless on the outside, flipped within': Detecting hidden defects in 2D dielectrics with light
'Flawless on the outside, flipped within': Detecting hidden defects in 2D dielectrics with light Gaby Clark Scientific Editor Alexander Pol Deputy Editor A material may appear flawless on the surface yet fail to function properly. The cause lies in structural defects hidden within two-dimensional thin films, which are considered key materials for next-generation semiconductor devices.
