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...
Magnetic field helps binary star systems form, new simulations indicate
Magnetic field helps binary star systems form, new simulations indicate Sadie Harley Scientific Editor Alexander Pol Deputy Editor New simulations show that interactions with a magnetic field can work to decrease the distance between still forming binary protostars. These results can help explain the characteristics of the binary star systems observed in the Milky Way. The results can also be extrapolated to binary black holes, giving insights into how supermassive black holes evolve.
Dynamic terahertz wavefront control using stretchable single-walled carbon nanotube-based metasurfaces
Dynamic terahertz wavefront control using stretchable single-walled carbon nanotube-based metasurfaces Sadie Harley Scientific Editor Alexander Pol Deputy Editor The terahertz (THz) frequency regime, sitting between microwaves and infrared light, has long promised revolutionary advances in wireless communication, security imaging and nondestructive sensing. A key roadblock, however, has been the lack of compact, dynamically tunable components capable of manipulating THz beams on demand....
'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...
Why do rival plants coexist? The secret is in the soil beneath the oaks
Why do rival plants coexist? The secret is in the soil beneath the oaks Lisa Lock Scientific Editor Alexander Pol Deputy Editor How can plants that compete for the same resources grow in the same area without one driving the other to extinction? Ecologists have been trying to answer this question for decades, and a surprising new explanation has now emerged: the soil surrounding oak trees acts as a silent mediator that restrains the dominant species and gives an advantage to weaker ones,...
'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.
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....
Leak on space station triggers brief safety alert
Leak on space station triggers brief safety alert Alexander Pol Deputy Editor Astronauts working on the International Space Station briefly sheltered in a docked capsule Friday as Russian colleagues assessed leak repairs, NASA said. Five astronauts had briefly entered the docked Dragon spacecraft as a precautionary measure—the capsule functions as a lifeboat of sorts in the case an evacuation is needed. NASA gave the all clear and the astronauts were able to return to their stations.
How gene swapping helped build the planet's decomposers
How gene swapping helped build the planet's decomposers Sadie Harley Scientific Editor Alexander Pol Deputy Editor Decomposers are crucial for keeping Earth habitable, breaking down dead biomass and returning key nutrients, such as carbon, nitrogen and phosphorus, to the ecosystem. Most decomposers, including fungi, survive through osmotrophy—a means of feeding by absorbing dissolved nutrients rather than engulfing prey. But how this method of feeding repeatedly arose across the eukaryotic...
