Fossil Fuel Emissions Threatens Carbon Dating Accuracy
The radiocarbon14C dating method has been used for decades to accurately determine the age of a wide range of artefacts. But our relentless use of fossil fuels has pumped a type of carbon into the atmosphere that is starting to confuse the dating technique. By 2050, scientists warn, new fabrics could have the same radiocarbon date as items 1,000 years old!
First predicted in the 1960s, like the Higgs boson before it, the pentaquark eluded science for decades until its recent detection at CERN’s LHCb collaboration. The discovery amounts to finding a new form of matter…
Forensic researchers from the University of Salzburg have developed a new method for establishing an exact time of death after as long as 10 days – a significant step forward from the current method of measuring core body temperature, which only works up to 36 hours after death.
1/60 minute. 1/3,600 hour. 1/86,400 day. 1/1 hertz. The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of a 133 55Cs caesium isotope corresponds to one second. But what does it look like? And where might you find a second?
Deep down, in huge subterranean caverns… Underneath the Franco-Swiss border… 300 feet underground… lies a beast of unprecedented power… and mystery. The Large Hadron Collider (LHC) that man summons to explore the uncharted corners of the sub-atomic realm… After two years of a deep slumber, the mighty beast has awoken…
Still in its early stages, El Niño has the potential to cause extreme and even devastating weather around the World. According to climate graphs, we have reached a 0.6 value for the ENSO. It’s a 60% probability. El Niño is now officially back.
One of the all-time most interesting elements in the Periodic Table, nitrogen is a colourless, odourless, inert diatomic gas that makes up to 78% of the Earth’s atmosphere. We breathe it everyday, although an atmosphere of pure nitrogen is nefarious to animal and human life. It is vital to life and plants simply strive on it. Nitrogen compounds are explosive, and nations have gone to war over it. It can feed… or kill.
What Pickpockets Know and Your Brain Would Rather Not Tell You
Be under no illusion. You saw the sign: “Pickpockets are operating in this area”. You reacted. Instantly. The first thing you did was to check your pockets or handbag for signs of financial solvability. All is well. You relax. Only now, you’ve become the “mark”… because you’ve just given away precious information about the location of your valuables around your body.
