RNA aptamers light up after ligand reacts.
Designing an organic reaction that works in cells is easier than designing a riboswitch, chemist says.
Users of Google’s Chrome browser can rest easy knowing that their surfing is secure, thanks in part to cryptographer Joppe Bos. He’s coauthor of a quantum-secure encryption algorithm that was adopted as a standard by the U.S. National Institute of Standards and Technology (NIST) in August and is already being implemented in a wide range of technology products, including Chrome.
Rapid advances in quantum computing have stoked fears that future devices may be able to break the encryption used by most modern technology. These approaches to encryption typically rely on mathematical puzzles that are too complex for classical computers to crack. But quantum computers can exploit quantum phenomena like superposition and entanglement to compute these problems much faster, and a powerful enough machine should be able to break current encryption.
In this article, we examine airborne microplastics in greater detail, explore detection methods, consider what we currently know about their health risks and highlight various mitigation strategies.
Unpacking the origins of microplastics
Airborne microplastics are a growing concern due to their presence across diverse environments, from lively city centers to isolated, untouched corners of the world.
The remains were discovered during excavations in 1938. Now, researchers have learned new information about his identity by analyzing DNA from his tooth.
The origins of the decoration lie in Vienna’s 17th district, where the inventor’s descendants are still making them for collectors around the world.
Site-selective immobilization of different bioreceptors on individual field-effect transistors, achieved through the use of thermal scanning probe lithography. Each bioreceptor can be tuned to detect a different disease.
New research explores nanobubble stability and its implications across a variety of real-world applications.
The University of Cape Town, along with the Giraffe Conservation Foundation, have conducted a large-scale study identifying significant cranial shape differences between four genetically distinct giraffe species. The findings suggest that these species exhibit unique developmental and morphological characteristics, which have implications for conservation efforts.
Taxonomic classification is critical for guiding good conservation strategies. Giraffes have long been categorized as one species with geographic variants, though advancements in research are reshaping this perspective.
In the study, “Heads Up—Four Giraffa Species Have Distinct Cranial Morphology,” published in PLOS ONE, researchers examined 515 giraffe skulls with 3D geometric morphometrics to analyze patterns of cranial variability. The dataset, the largest of its kind, included specimens from museum collections, wild populations, and taxidermy sources across Africa.
