Humans have been making symbols for numbers for thousands of years. Different cultures developed their own symbols, but all use addition and multiplication, suggesting arithmetic is a universal truth.
The Deniliquin structure spans up to 520 kilometres in diameter. This exceeds the size of the near-300km- wide Vredefort impact structure in South Africa, which to date has been considered the world's largest.
We’ve known about the vents above for a long time, but this is basically a completely new ecosystem below.
The scientists hope the breakthrough is the start of a new era. Though this experiment was performed with simple, two-atom molecules, they plan to work their way up to handling larger and more complex molecules.
Technique could replace current systems that rely on vapour compression of powerful greenhouse gases.
Deep beneath the soil of a Massachusetts forest, an international team of researchers has uncovered a multitude of mysterious, gigantic viruses of unprecedented ecological diversity.
US scientists have observed metal cracking and fusing back together, in a discovery that could pave the way for self-healing machines, vehicles and bridges.
Scientists described how pieces of pure platinum and copper spontaneously healed cracks caused by metal fatigue during nanoscale experiments that had been designed to study how such cracks form and spread in metal placed under stress.
Space propulsion company Pulsar Fusion has started construction on what it claims is the largest practical nuclear fusion rocket engine ever built.
The study suggests that gaining insights into how the spirals are related to cognitive processing could significantly enhance our understanding of the dynamics and functions of the brain.
In a remarkable scientific breakthrough researchers have discovered the lightest isotope of the rare and rapidly decaying element, astatine.
U.S. scientists argue that chance alone cannot consistently produce the highly complex molecules found in all living creatures. To produce billions of copies of intricate objects like proteins, human hands, or iPhones, the universe needs a 'memory'.
Researchers have created synthetic human embryos using stem cells, according to media reports. Remarkably, these embryos have reportedly been created from embryonic stem cells, meaning they do not require sperm and ova.
Scientists now find that the earliest leafy plants did not have Fibonacci spirals, contradicting our initial assumptions on plant evolution.
Earth's largest continental rift, the East African Rift (EAR) system, has been something of a mystery for geologists – but a new study combining computer models with GPS satellite data appears to have found an explanation.
