Astrophysicists have long been intrigued by the nature of the first stars in the universe, which have left only traces of their presence. However, evidence traced in images from the James Webb Space Telescope now suggests that after the appearance of the first stars, there were fusion-powered balls of heat and fury, known as “chonker”

An astronomer from South Korea has recently reported that a sunspot four times the size of Earth is lined up with the Sun, and it is so large that it could be seen with the naked eye provided that the observer has the appropriate equipment to observe it safely. The astronomer has advised amateur astronomers
A recent study by a group of international researchers has revealed that toxic substances from gut bacteria can interfere with the functioning of fat cells and contribute to obesity. The study’s findings could help in the development of new treatments for excessive and dangerous weight gain in the future. According to the researchers, these toxic
The Solar System is abundant in water, with planets and moons loaded with it, and comets from the far reaches carrying it. However, while water ice has been detected in the asteroid belt, its vapor has been strangely missing until now. But thanks to the James Webb Space Telescope (JWST), scientists can now confirm that
A group of scientists from École Polytechnique Fédérale de Lausanne (EPFL) has built a demonstration of the plasma transducer, which is a set of parallel wires that can ionize air particles to create a loudspeaker. They have come up with a new concept called the active “plasmacoustic metalayer” that can cancel out noise. The scientists
As the world moves towards renewable energy, there is a need for new technologies for storing and distributing energy to homes and electric vehicles. The current standard for energy storage has been the lithium-ion battery containing liquid electrolytes. However, this solution is far from ideal due to its low efficiency and the liquid electrolyte’s propensity
Cryptocurrency mining has become increasingly popular in recent years, but little attention has been paid to the environmental impact of this activity. Estimates suggest that the global electricity usage for cryptocurrency assets like Bitcoin is between 120 and 240 billion kilowatt-hours per year, which is more than what some countries like Argentina and Australia use
TikTok has filed a lawsuit against the state of Montana to stop the implementation of an overall ban on the video-sharing app. The ban, set to start in 2024, has been deemed unconstitutional by TikTok as it violates the right to free speech protected by the constitution. Montana Governor Supports Ban Montana Governor Greg Gianforte
Research has shown that what goes on inside our heads can profoundly influence our body’s typical functions. A new study conducted by a team of researchers from Australia suggests that mental illness might manifest in the body even more obviously than it does in the brain. The study finds that poor physical health scores could
As the number of computer vulnerabilities and bugs continue to increase, cyber defenders are struggling to track, prioritize and prevent all the threats and attacks. With over 213,800 known “keys” or vulnerabilities in computer systems, and likely many more unknown, it is impossible for any one person or team to manage all the information. The
A new study by the University of Florida has found that limiting the use of ride-hailing apps such as Uber or Lyft can have a negative impact on the transportation ecosystem of a city. The study analyzes how a policy implemented by the city of Shanghai to restrict the use of ride-hailing apps affected the
Betelgeuse, the red giant star, has been exhibiting unusual behavior since the Great Dimming that occurred in 2019 and early 2020. The fluctuations in brightness that were a regular occurrence have changed, and the star has become uncharacteristically bright. Currently, Betelgeuse is at 142 percent of its normal brightness, with a steady upward trend for
The Chinese government has warned users of computer equipment that is considered sensitive to stop purchasing products from Micron Technology Inc., the largest memory chipmaker in the United States. The Cyberspace Administration of China has stated that Micron products pose unspecified “serious network security risks” that threaten national security and the country’s information infrastructure. The
Aspartame, an artificial sweetener approved by the US Food and Drug Administration (FDA) in 1981, is widely used in low-calorie foods and drinks. While it is found in nearly 5,000 different products consumed by adults and children, there have been question marks over potentially adverse reactions to the sweetener in some people. A 2022 study
Multiple Sclerosis (MS) is an autoimmune disease that affects 2.8 million people around the world. The disease causes the immune system to damage the brain and spinal cord, leading to symptoms such as fatigue, vision disturbance, problems with mobility and balance, and cognitive dysfunction. Although the exact cause of MS remains unknown, scientists have suggested
