New research is shedding light on the brain‘s role in depression, particularly through the discovery of an enlarged salience network in people suffering from the condition. This brain network, located primarily in the frontal cortex and striatum, is responsible for processing rewards and focusing attention on significant stimuli. The findings open promising avenues for early

Woolly mammoths have long been thought to have disappeared due to a combination of factors, such as climate change and human activity. However, a recent study proposes an unexpected hypothesis: pollen allergies may have played a role in their extinction. The study suggests that at the end of the last Ice Age, a surge in
On September 17, 2024, a fascinating asteroid named 2024 ON zipped past Earth, offering scientists a rare view of a snowman-shaped space rock. While the object was classified as a potentially hazardous asteroid due to its proximity to our planet, it posed no immediate threat and passed safely at a distance of 620,000 miles. Radar
Blue Origin’s New Glenn rocket, the much-anticipated rival to SpaceX‘s Falcon Heavy, has taken a major step forward with a successful second-stage hot-fire test. This crucial test was conducted to validate key interactions between the rocket’s subsystems, its two BE-3U engines, and the ground control systems. The test, which lasted 15 seconds, represents a major
In 1859, when Charles Darwin published On the Origin of Species, the Earth experienced one of the most powerful solar storms in recorded history. Telegraph systems across Europe and North America malfunctioned, sparking fires in some places. This event, later known as the Carrington event, was preceded by the first confirmed observation of a solar
SpaceX‘s upcoming Crew-9 mission to the International Space Station (ISS) has been postponed because of the arrival of Tropical Storm Helene. Originally set to launch on September 26th from Florida’s Cape Canaveral Space Force Station, the launch is now delayed by at least two days. The tropical storm is expected to escalate into a Category 3
Semi-aquatic lizards, such as the water anole (Anolis aquaticus), have a unique ability to stay submerged for extended periods by creating an air bubble around their snout. This behaviour, first observed in 2018, has now been confirmed in 18 other anole species. The air bubble helps the lizards breathe while underwater, enabling them to remain
An asteroid, about the size of a city bus, will soon become a “mini-moon” as it will get caught in Earth’s gravitational pull. Named 2024 PT5, this asteroid is expected to enter Earth’s orbit on September 29, 2024, and will stay until November 25. While the term “mini-moon” may sound peculiar, it is used by
The traditional view of black holes, as proposed by Karl Schwarzschild in 1916, suggests they consist of two main features: a singularity and an event horizon. This model faces challenges when combined with quantum mechanics, especially following Stephen Hawking’s discovery of Hawking radiation in the 1970s. According to this theory, black holes emit radiation due
Recent mathematical research has unveiled a fascinating new class of shapes known as “soft cells.” These shapes, characterised by their rounded corners and pointed tips, have been identified as prevalent throughout nature, from the intricate chambers of nautilus shells to the way seeds arrange themselves within plants. This groundbreaking work delves into the principles of
The life of a Roman gladiator was filled with violence and danger, but the notion that these fighters always battled to the death is somewhat exaggerated. Historical evidence shows that while fatalities did occur, they were not as commonplace as popular media suggests. Researcher Alfonso Manas from the University of California, Berkeley, told LiveScience that
An international team of researchers, led by scientists from Stockholm University’s Department of Astronomy, has discovered a higher number of black holes in the early universe than was previously recorded. Using the NASA Hubble Space Telescope, this team found black holes among faint galaxies formed shortly after the Big Bang event. These findings may help
NASA‘s Europa Clipper mission is on track for its scheduled October 10 launch, aiming to explore Jupiter’s icy moon, Europa. Scientists believe Europa could be one of the most promising places to find the conditions for life beyond Earth. The spacecraft will travel 1.8 billion miles (2.9 billion kilometres) to study whether the moon’s icy
A new study suggests that people from the Pitted Ware Culture (PWC) in ancient Scandinavia likely built boats from animal skins, possibly seal hides, to fish, hunt, and trade. The PWC was a Neolithic group of hunter-gatherers who lived between 3500 and 2300 BC in regions near the Baltic and North Seas. Their survival heavily
Chandrayaan-4 mission has received approval from the Union Cabinet, led by Prime Minister Narendra Modi, on Wednesday. This marks another significant milestone in India’s lunar exploration efforts. Unlike previous missions, Chandrayaan-4 will not only aim for a successful landing on the Moon but will also focus on returning to Earth. This mission will demonstrate critical
A recent excavation in Egypt has uncovered a 3,200-year-old military barracks containing a treasure trove of ancient artefacts, including a sword inscribed with the name of Pharaoh Ramesses II. This discovery sheds light on Egypt’s military operations during Ramesses II’s reign, a time when threats from the Libyans were growing. The barracks also contained storerooms
MIT physicists have put forward a theory that the wobble in Mars’ orbit could be caused by primordial black holes, which may constitute dark matter. According to the research, these tiny black holes formed after the Big Bang and could be passing through our solar system, affecting the orbit of planets like Mars. David Kaiser,
Earth will have a close encounter with the asteroid Apophis, also known as the “God of Destruction” on Friday, April 13, 2029. Named after the Egyptian deity of chaos, this massive asteroid will come within 19,000 miles (30,600 kilometres) of our planet, close enough to be visible to the naked eye. However, recent research suggests that
Astronomers have reportedly detected an extraordinary event – a deep space radio signal that took 8 billion years to reach Earth. The radio burst, named FRB 20220610A, is one of the most powerful and distant signals ever captured. Fast radio bursts (FRBs) like this are brief but incredibly strong, leaving scientists questioning their origins. The burst
Primordial black holes, formed shortly after the Big Bang, may pass through our solar system every decade, according to recent research. These black holes, much smaller and lighter than typical ones, could cause minor gravitational disruptions that scientists could detect. Researchers suggest that tracking these disruptions may help understand dark matter, an elusive substance believed
