The study, published in iScience, investigated whether participants could experience a sense of embodiment with virtual "hands" resembling tweezers compared to a more human-like virtual hand.
Martian Meteorites Unveil Secrets of Mars’ Internal Structure
Recent research led by researchers from Scripps Institution of Oceanography has provided new insights into the structure of Mars using meteorites that originated from the planet. The study, published in Science Advances, analyzed Martian meteorites collected from Antarctica and Africa. These meteorites, formed about 1.3 billion years ago and were ejected from Mars, offer valuable information about the planet’s mantle and crust.
Internet Addiction in Teens May Lead to Lasting Brain and Behavioural Changes
A study by UCL researchers has found that adolescents with internet addiction exhibit significant changes in brain activity, potentially leading to further addictive behaviours. Published in PLOS Mental Health, the study reviewed 12 articles involving 237 adolescents aged 10-19 diagnosed with internet addiction between 2013 and 2023.
Breakthrough Study Redefines Higgs Mechanism with Magnetic Quivers
An international research team led by researchers from the University of Vienna has made notable advancements in quantum physics by reinterpreting the Higgs mechanism through a concept called "magnetic quivers." Their findings, published in Physical Review Letters, offer new insights into how elementary particles acquire mass and how phase transitions occur in quantum field theory (QFT).
Bronze Age Greek Armour Found to Be More Than Ceremonial
Recent research has re-evaluated the purpose of a 3,500-year-old Mycenaean suit of bronze armour found in a Greek tomb, suggesting it was not merely ceremonial but used in battle. Discovered in Dendra and known as one of the finest examples of Mycenaean armour, the suit has long been debated since its discovery in the 1960s.
Epidurals Linked to Dramatic Drop in Maternal Health Risks
A recent study has discovered that receiving an epidural during labour is associated with a 35% reduction in severe maternal health complications, and the benefits are even more pronounced for those with preterm births. Epidurals, which involve injecting an anaesthetic around the lower spinal cord to relieve labour pain, have been recognized for their pain-relieving properties, but this study highlights additional potential benefits.
Brazilian Weed Found to Contain Valuable CBD Compound
Scientists have identified cannabidiol (CBD) in a common Brazilian plant called Trema micrantha blume. This shrub, which grows widely across Brazil and is often considered a weed, contains CBD in its fruits and flowers but does not have tetrahydrocannabinol (THC), the psychoactive compound found in cannabis.
Study Traces Neanderthal DNA Influence in Modern Humans 47000 Years Later
Research into human DNA from both prehistoric and modern sources reveals that Neanderthals and early modern humans interbred approximately 47,000 years ago, with this interbreeding lasting around 6,800 years. Neanderthals, who inhabited Europe and Asia, and Homo sapiens, who evolved in Africa, began to mix when modern humans migrated out of Africa. This interbreeding contributed 1% to 2% of Neanderthal DNA to the genomes of contemporary humans outside Africa.
Viking Age Silver Ingot Unveils Isle of Man's Rich Trading History
A Viking Age silver ingot found on the Isle of Man has been recognized as an important historical artefact. The small ingot, which weighs approximately 11 grams, was found while researchers were exploring the island between Northern Ireland and England. Analysis by the University of Liverpool and Manx National Heritage revealed that the ingot comprises 88% silver.
Multiple Populations Shaped the Evolution of Modern Humans in Africa
Modern humans (Homo sapiens) originated in Africa around 300,000 years ago. Prior to this, earlier hominins such as Homo erectus and Homo heidelbergensis inhabited Africa, Europe, and Asia. Homo heidelbergensisled to the emergence of Neanderthals in Eurasia, Denisovans in Asia, and modern humans in Africa. The precise reasons why Homo sapiens evolved specifically in Africa remain a central question in evolutionary science.
From Whale Blubber to Oil: A New Era of Energy Transition Begins
The transition from oil as a primary energy source is likened to the historical shift from whale blubber, which once powered society until overuse led to its decline. This change will involve intricate geopolitical, technological, and economic shifts as reliance on oil diminishes.
Solving the Cosmic Puzzle of the Three-Body Problem
The three-body problem is a challenging physics issue that has intrigued scientists since Isaac Newton’s era. It involves calculating the gravitational interactions between three bodies, which is significantly more complex than the two-body problem, where two objects predictably orbit each other. Introducing a third body disrupts this predictability, making the system’s behaviour highly sensitive to the initial positions, velocities, and masses of the bodies. Small parameter changes can lead to drastically different outcomes, like balancing on a narrow ridge.
Breakthrough in Quantum Memory Brings Quantum Internet Closer to Reality
A recent study has made notable progress in the production, storage, and retrieval of quantum data, moving us closer to developing a quantum internet. Quantum information, carried by qubits, tends to be unstable over long distances, often becoming lost or fragmented during transmission. Effective quantum memory devices are essential for storing and retransmitting qubit states to overcome this challenge, ensuring signal integrity across a network.
Sleep Study Shows Brain Rehearsing Future Activities in Dream State
A recent study suggests that neurons in the brain's memory centre may revisit past experiences during sleep and prepare for future activities. Researchers from the University of Michigan analyzed brain wave patterns from rats as they navigated mazes and then during subsequent sleep periods. By tracking neuron activity across different stages of wakefulness and sleep, they could map the activity of individual neurons to specific points in the maze, even when the rats were asleep.
Vigorous Exercise Linked to Potential Immune Risks in Firefighters
A recent study investigated how excessive vigorous exercise might impact the immune system by analyzing over 4,700 post-exercise fluid samples from firefighters. This research highlights potential risks for those in physically demanding professions, such as emergency responders and athletes, who may be more susceptible to viral respiratory infections following intense workouts due to reduced inflammatory activity.
Lava Hole on Mars May Hold the Key to Future Human Habitats
Human missions to Mars will require shelters to safeguard against radiation, temperature fluctuations, and dust storms. One promising shelter option is to use underground lava tubes, similar to those on Earth and the Moon. These tubes might have collapsed sections called skylights that provide access to the underground spaces.
Breakthrough Research Explores Brain Resilience to Alzheimer's Disease
A recent study investigated why some individuals with brain changes characteristic of Alzheimer's disease do not exhibit symptoms, potentially revealing pathways for new treatments. Researchers from the Netherlands Institute for Neuroscience examined brain tissue samples from the Netherlands Brain Bank, which includes over 5,000 donated brains from individuals who passed away from brain diseases. They focused on 12 samples from people who showed Alzheimer's pathology but remained cognitively healthy, indicating a rare form of resilience to the disease.
Insufficient slow-wave sleep in seniors linked to higher dementia and Alzheimer's risk
A recent study highlights a significant link between insufficient slow-wave sleep (SWS) in people over 60 and an increased risk of dementia. SWS, a critical stage in the sleep cycle that lasts about 20-40 minutes and occurs roughly every 90 minutes, is essential for various aspects of health, including muscle, bone, immune function, and brain health. It is crucial in clearing metabolic waste from the brain, including proteins associated with Alzheimer's disease.
