The intriguing phenomenon of tidal disruption events in the centers of galaxies has puzzled astronomers for decades. Originally theorized by Jack G. Hills and Martin Rees in the 1970s and 80s, these events occur when a star is torn apart by a supermassive black hole, resulting in a spectacular display of fireworks known as a

Fear is a primal and instinctual emotion that can grip us with an intensity that is hard to shake off. It triggers a series of chemical changes in our bodies that rapidly prepare us for a response to potential threats. However, when this fear response mechanism malfunctions, it can lead to debilitating conditions such as
Research conducted by Western Sydney University has brought to light the disturbing presence of PFOS (perfluorooctane sulfonate) chemical contamination in the livers of deceased platypuses in eastern New South Wales. The study, a first of its kind in Australia, analyzed liver samples from nine deceased platypuses collected over a two-and-a-half-year period. Lead researcher Katherine Warwick,
The ratchet mechanism is a critical component in various systems, converting disorderly or random motion into orderly, directed movement through a process called spontaneous rectification. This mechanism typically involves a gear and a pawl that restricts the movement of the gear in one direction. In biological systems, the Brownian ratchet concept helps explain the mechanism
In a world where technology is constantly advancing, the concept of printed electronics is revolutionizing the way we think about electronic circuits. These circuits are not only thin and bendable, but they also have the potential to bring about groundbreaking innovations that could change the way we interact with everyday objects. By incorporating printed electronics
Polymers are complex materials composed of long chains of molecules that determine their properties. Traditionally, external forces on polymers have been seen as damaging, but recent studies have shown that these forces can actually have beneficial effects on polymer properties. While the field of mechanochemistry has made strides in understanding how external forces can alter
In a strategic move to enhance its artificial intelligence capabilities and expand its market share in the tech industry, AMD has announced the acquisition of server maker ZT Systems in a deal worth $4.9 billion. This acquisition comes at a crucial time as AMD aims to compete with industry leader Nvidia in the AI sector.
Alzheimer’s disease is a devastating condition that affects millions of people worldwide. Despite years of research, the exact cause of brain damage in Alzheimer’s has remained elusive. A recent study led by Emory University in the US has shed new light on the role of protein accumulation in the progression of the disease. One of
Black holes are known for their destructive nature towards stars that come too close to them. However, in rare instances, a star may survive the encounter and be pulled into an orbit around the black hole. This unique occurrence leads to a much slower and drawn-out death for the star, providing valuable insights into various
The use of plastics in manufacturing has been a major contributor to environmental issues, prompting researchers to find eco-friendly alternatives. The University of Warwick has made significant progress in this endeavor by exploring organic eutectics as a replacement for traditional plastics. Eutectic Compositions Researchers at The University of Warwick have discovered that certain mixtures of
As you wake up to a cold, damp morning, you may notice that your knee is bothering you again. It’s a common belief that the weather has a direct impact on joint and muscle pain. However, recent studies have shown that there is actually no direct link between weather conditions and most aches and pains.
Recently, the Earth was struck by an intense solar storm, with conditions of a level-four geomagnetic storm observed by a specialized center at the US National Oceanic and Atmospheric Administration (NOAA). This solar storm has the potential to bring the northern lights to night skies even further south than usual, with auroras potentially visible in
Color Vision Deficiency (CVD) affects a significant portion of the population, with nearly 8% of genetic males and 0.5% of genetic females experiencing some form of color blindness. This condition, also known as Color Vision Deficiency, hinders individuals’ ability to discern specific colors, making it challenging to process visual data. In the field of meteorology,
Google’s position as a monopoly in the market has been confirmed by a US judge, highlighting its use of dominance to solidify its market position. With a staggering 80% of Alphabet’s revenue derived from advertising, totaling US$146 billion in 2021, Google’s influence in the digital advertising sphere is undeniable. The core of its revenue stream
Boeing’s new chief executive, Kelly Ortberg, is determined to reset relations with a key union, the International Association of Machinists and Aerospace Workers, amid negotiations for a new labor contract. Following a productive conversation with the presidents of IAM 751 & W24 in Seattle, Ortberg expressed his commitment to rebuilding the relationship and reaching a
Imagine a scenario where a group of lemmings joyfully climb up a mountain only to suddenly plummet off a cliff to their doom. This idea of lemmings running off cliffs is a myth, but it serves as a metaphor for critical points in various systems. Critical points are defined as the moment when the behavior
