A new report released by an international research team of encryption experts sheds light on the monumental effort, massive crowdsourcing, and digital programming required to translate the cryptic message of a notorious serial killer that remained a mystery for half a century. While one of the experts uploaded a video summary of their method to YouTube in 2020, the new report from the research team provides a more comprehensive view of the extensive effort involved in accomplishing this feat. A man who called himself Zodiac in 1968-69 had killed at least five people in the northern region of California, USA. During that time and in the following years, the killer had sent a series of letters to local newspapers along with a total of four encrypted messages. Authorities have yet to officially identify ...

Music, deeply rooted in human history, is considered a universal language. It is used in a wide range of contexts, from rituals to entertainment, in many cultures. Our senses as well as our mental and emotional states are intertwined with music. This is due to the effect of sound frequencies on the brain. Interaction Between the Brain and Music The effect of music on the brain is diverse and depends on many factors. However, music starts with the collection of sound waves coming from our ears. These sound waves reaching the brain are processed there. Different regions of the brain respond differently to elements such as rhythm, melody, and tone. Role of Frequencies Sound is formed by vibrations at various frequencies. The frequency range we can hear is between 20 and 20,000 Hertz. This frequency range plays a critical role in the psychological and emotional effects on humans. -Low Frequencies (20-250 Hz): Characteristics such as rhythm and bass notes are typically found in low frequenc...

One of the most ethical challenges for cybersecurity professionals are information access and privacy. Striking the right balance between customer security and data protection is a delicate field. In the ever-evolving realm of cybersecurity, professionals navigate an environment demanding thoughtful decision-making, at the intersection of technological innovation and ethical responsibility.   Integrating ethical principles into cybersecurity practice is not merely a theoretical exercise; it i s a dynamic and evolving process shaped by the rapidly changing nature of technology, artificial intelligence, and the increasing connectivity of the virtual world.   Ethical aspects take center stage in information services' processes, as professionals grapple with the potential abuse of accessing information. Compliance with privacy and ethical standards is a crucial for customer safety, requiring a nuanced approach to balancing ethical standards when handling sensitive customer in...

British scientist Peter Higgs, who gave his name to the Higgs boson, has died at the age of 94. An English physicist, he was among the scientists who developed the theory in the 1960s that explains why everything in the Universe has mass.  About 50 years later, this scientific breakthrough was achieved.  Experiments conducted in 2012 at the Large Hadron Collider at the CERN laboratories in Geneva, Switzerland, confirmed the existence of the Higgs boson. A year after this event, in 2013, Higgs was awarded the Nobel Prize in Physics. -Edinburgh University stated that Higgs "enriched our understanding of the world around us with his vision and imagination." British particle physicist Dr. Clara Nellist was at CERN when the Higgs boson was discovered in 2012, causing a sensation worldwide. Dr. Nellist said, "The Higgs boson is truly a special particle. It's associated with the acquisition of mass by other fundamental particles. When particles enter the Higgs field, they g...

  On April 8th, a particularly followed solar eclipse event occurred, especially in North America. Scientists argue that such awe-inspiring cosmological events can have a strong impact on our psychology. In Herodotus' writings, it's described as, "As the battle raged on, the day suddenly turned into night. When the Medes and Lydians observed this change, they halted the battle and agreed to negotiate peace terms." While this year's solar eclipse on April 8th in North America may not evoke such dramatic reactions, recent research suggests that such awe-inspiring cosmological events could have a profound impact on our psychology. Experiencing a total solar eclipse, made possible by a series of celestial coincidences, is perhaps one of the most awe-inspiring events. Research indicates that witnessing this remarkable phenomenon inspires humility and encourages us to show more concern for others. -Sean Goldy, a psychologist at Johns Hopkins University who studied the p...
