Phys.org / A promising technique to steer laser-produced THz radiation in air
Terahertz radiation (THz), electromagnetic radiation with frequencies ranging from 0.1 and 10 THz, is central to the functioning of various technologies, including imaging, sensing and spectroscopy tools. While THz radiation ...
Phys.org / Decoding the giant Y of Silene latifolia: Evolutionary insights into an unusually large sex chromosome
A high-quality genome assembly of Silene latifolia was generated by researchers at CNRS/Université Claude Bernard Lyon 1 and collaborating institutions. The team identified extensive recombination suppression, large-scale ...
Phys.org / Astronomers investigate the evolution of a newly detected supernova
An international team of astronomers has investigated a newly detected Type II supernova designated SN 2024jlf. The new study, detailed in a paper published Jan. 30 on the arXiv pre-print server, yields important information ...
Phys.org / Crossing the blood–brain barrier with a payload via engineered bacteria
Researchers at the National University of Singapore have reported crossing the blood–brain barrier with help from a modified Lactobacillus plantarum. By delivering an appetite-regulating hormone directly to the olfactory ...
Phys.org / History of the Fulani, one of the largest pastoral populations in Africa, unraveled in study
Researchers have uncovered the origins and genetic diversity of the Fulani, one of Africa's largest pastoral populations. The study reveals a complex genetic ancestry with influences from both North and West Africa, shaped ...
Phys.org / Sex as a formality: Study shows male stick insects have lost their reproductive function
While most animals reproduce sexually, some species rely solely on females for parthenogenetic reproduction. Even in these species, rare males occasionally appear. Whether these males retain reproductive functions is a key ...
Phys.org / From photons to protons: Team makes breakthrough in high-energy particle detection
Particle detectors play a crucial role in our understanding of the fundamental building blocks of the universe. They allow scientists to study the behavior and properties of the particles produced in high-energy collisions. ...
Phys.org / New fish species with 'face paint' named after Studio Ghibli character
Researchers in China have named a newly discovered fish species after the Studio Ghibli character San from "Princess Mononoke," based on its similar facial markings.
Phys.org / Landmark studies track source of Indo-European languages spoken by 40% of world
A pair of landmark studies, published Wednesday in the journal Nature, has finally identified the originators of the Indo-European family of 400-plus languages, spoken today by more than 40% of the world's population.
Phys.org / Astronomers announce largest collection of comets found outside our solar system
For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are orbiting.
Phys.org / Does the universe behave the same way everywhere? Weak gravitational lensing could provide an answer
A study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the assumption of cosmic homogeneity and isotropy, known as the Cosmological Principle, by leveraging weak gravitational ...
Phys.org / Plant extract inspires new chemistry and new early lead against triple-negative breast cancer
Chemists at Emory University have invented a reaction to streamline the total synthesis of a compound, phaeocaulisin A, extracted from a plant used for centuries in traditional Chinese medicine.
