Global warming is posing an existential threat to the Siberian tundra, the frozen lands near the Arctic Circle, researchers have said in a new study. The researchers from the Alfred Wegener Institute for Polar and Marine Research, Germany, prepared a computer simulation of how global warming could affect the tundra — a special ecosystem consisting

As we age, the retention power of our memory often degrades. This makes performing everyday tasks difficult. It gets very difficult to remember things. For instance, elderly people could forget by afternoon what they ate for breakfast. They may even find it difficult to recall a conversation they had with someone. One key brain region
Coral reefs hide within them several secrets that are difficult for scientists to record and study. Experts must do rigorous analyses to determine reef health based on sound recordings because coral reefs have a complex soundscape. Now, in a new research, artificial intelligence (AI) can track the health of coral reefs by learning the “song
The National Aeronautics and Space Administration, the USA’s space agency, has conducted several probes and expeditions over the years to find answers to several hidden answers. In 1977, NASA launched Voyager 1 and Voyager 2 to fly across the solar system and give humanity unprecedented access to the world far away from us. On each
Black holes are thought to reside at the centre of most galaxies, including our Milky Way, holding important clues to the functioning of these giants. A group of researchers has now found a previously overlooked trove of massive black holes in dwarf galaxies. Black holes are usually detected when they actively grow by consuming gas
On August 15, 1977, a mysterious ‘Wow!’ signal had briefly blared through a radio telescope that lasted for 72 seconds. Now, almost half a century later, researchers may have discovered the source of the alleged alien broadcast. A study recently published on May 6 indicates that the signal likely came from a Sun-like star located
For the past ten years, NASA’s Curiosity rover has been trundling around the surface of Mars, taking photos in its quest to understand the history and geology of the red planet and perhaps even find signs of life. Last week it took a photo which appeared to show a doorway carved into the rock. It’s
For many people around the world, watching television has long been a favourite pastime. But if you’re watching television for long periods of time, it’s time to reconsider your daily routine. According to a new study, watching TV for lengthy durations can increase the risk of coronary heart disease, regardless of one’s genetic composition. The
An international group of astronomers has revived an alternative gravity theory, known as Milgromian Dynamics or MOND. A majority of astronomers agree that there’s something out there, called a ‘dark matter’, which causes spiral galaxies to rotate faster than they should. If we follow the rules of physics, galaxies rotate so quickly that they should
A mirror world is a common trope in fantasy and fiction, but it may also be the answer to one of Space’s biggest mysteries today. A group of scientists behind a new research paper suggest that a “mirror world” of particles that remains unseen from us may be the answer to the Hubble Constant problem.
Imagine an asteroid that is four times as big as the Empire State Building. Now, imagine it hurling through space at a speed of 47,200 mph (76,000 km/h), which is 20 times faster than a bullet. This is how an asteroid is speeding towards Earth. This asteroid, named 7335 (1989 JA), is estimated to just
Scientists have long tried to create new allotropes (forms) of carbon because of their versatility and usefulness for the industry. But only limited success was achieved so far. That is set to change now. In a major breakthrough, researchers at the University of Colorado Boulder, US, have successfully synthesised the long-hypothesised “next-generation wonder material” graphyne.
NASA is planning to make another attempt at testing the Artemis 1 SLS rocket in early June for the last time before launching it into space. The space agency said it will bring the Space Launch System (SLS) rocket and Orion spacecraft to the launchpad at the Kennedy Space Centre in Florida in early June
NASA will soon be scaling up its documentation of environmental and societal changes on Earth. The space agency will achieve this by working in collaboration with its partners in Europe and Japan, namely ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency). The collaboration will include utilising all the Earth-observing satellite data available so
What is it like to be on the surface of Mars or Venus? Or even further afield, such as on Pluto, or Saturn’s moon Titan? This curiosity has driven advances in space exploration since Sputnik 1 was launched 65 years ago. But we’re only beginning to scratch the surface of what is knowable about other
Photonic materials are the ones that emit, detect or manipulate light. These materials play a crucial role in various sectors such as telecommunications, data processing and storage, and solar cells. Because of their vast usage, there is a continuous need to make them efficient. Researchers, at the University of Central Florida (UCF), are developing new
With the growing pace of development, researchers have been experimenting with various artificial intelligence technologies through devices and products. However, implementing artificial intelligence in electronic device requires customised hardware, which in turn result in high power consumption. It has been a challenge for researchers to solve issues related to high power consumption that limits the integration
NASA’s Cold Atom Lab aboard International Space Station (ISS) has come up with a discovery that can give a new direction to quantum research. In this lab, researchers have experimented with gas to form an exotic material. Gas, when cooled to nearly absolute zero (minus 459 degrees Fahrenheit, or minus 273 degrees Celsius) formed small,
NASA astronauts and officials on Wednesday said Boeing’s Starliner space capsule is ready for its uncrewed launch this week to the International Space Station, a long-delayed test mission meant to demonstrate the aerospace giant can safely fly humans in space. Boeing’s CST-100 Starliner capsule, a gumdrop-shaped astronaut pod, has experienced multiple setbacks in recent years.
Unidentified flying objects or UFOs have always been a subject of mystery and intrigue for the scientific community. Yet, studying these objects has often been dismissed as a non-serious discipline or pseudoscience. However, things changed this week. For the first time in 50 years, the US Congress held an open hearing on unidentified aerial phenomena
