Scientists have developed a method for generating fast, bright proton beams using a high-repetition-rate laser-plasma accelerator. This work, published in Nature Communications, resolves several long-standing challenges and ushers this technology to the threshold of real-world applications—all thanks to a stream of water. Go to Source Volusia County deputies deployed spike strips and a K-9 to end the pursuit, which began when the suspect refused to exit his vehicle during a traffic stop Go to Source 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 regarding the evolution of this supernova and the nature of its progenitor. Go to Source As night falls on the Atacama desert in northern Chile four giant telescopes turn their gaze towards the star-strewn heavens. Go to Source Does the universe behave the same way everywhere? Weak gravitational lensing could provide an answerA 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 lensing—a light distortion effect described by general relativity—in astronomical images collected by new observatories such as the Euclid Space Telescope. Finding evidence […] A new study has unveiled new insights into the effects of massive stars on nearby molecular gas and star formation in the W4 super-large HII region. Go to Source How would detecting methane help astronomers identify if exoplanets, or even exomoons, have life as we know it, or even as we don’t know it? This is what a recent study published in The Astronomical Journal hopes to address as a team of researchers led by the NASA Goddard Space Flight Center investigated how a […] Qubits—the fundamental units of quantum information—drive entire tech sectors. Among them, superconducting qubits could be instrumental in building a large-scale quantum computer, but they rely on electrical signals and are difficult to scale. Go to Source 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 waves have been manipulated in different ways over the past decades, controlling their direction in air has so far remained a challenge. Go to Source […] Excitons, encountered in technologies like solar cells and TVs, are quasiparticles formed by an electron and a positively charged “hole,” moving together in a semiconductor. Created when an electron is excited to a higher energy state, excitons transfer energy without carrying a net charge. While their behavior in traditional semiconductors is well understood, excitons act […] The rapid advancement of technologies like artificial intelligence (AI) and the Internet of Things (IoT) has heightened the demand for high-speed, energy-efficient memory devices. Traditional memory technologies often struggle to balance performance with power consumption. Go to Source “Climate change is real.” That stark and undeniable statement spearheads a new call to action in a paper published in a special edition of the European Physical Journal Special Topics, focusing on energy saving in physics research and applications. Go to Source Tesla believed he received alien messages at the end of the nineteenth century It is not a secret that there are numerous inventions of Tesla that have been attributed to other “inventors”, among these inventions are the radio and the first machine capable of searching for extraterrestrial life. The FBI seized documents including numerous […] Archaeologists estimate that the period of existence of the Olmecs was between 200 and 500 thousand years before Christ. According to several studies, there were three areas where the ancient Olmecs focused their reign, these were mainly San Lorenzo, Veracruz; Tabasco Sale and Tres Zapotes, close to Santiago Tuxtla, Veracruz. The great Olmec civilization […] The man pointed a gun at two different officers before he was shot and taken into custody; he has been charged with attempted murder Go to Source |
