What were they thinking?! These erroneous guesses about tech in 2018 would shatter any crystal ball.
The spectacular Geminid meteor shower peaks the night of December 13/14. Although many people consider it to be a poor cousin to August’s Perseid shower, the Geminids often put on a better show. This year, observers can expect to see up to 120 “shooting stars” per hour — an average of nearly two per minute — under a dark sky.
The Earth is far more alive than previously thought, according to “deep life” studies that reveal a rich ecosystem beneath our feet that is almost twice the size of that found in all the world’s oceans. Despite extreme heat, no light, minuscule nutrition and intense pressure, scientists estimate this subterranean biosphere is teeming with between 15bn and 23bn tonnes of micro-organisms, hundreds of times the combined weight of every human on the planet.
Marmoset monkeys exist on a branch of the evolutionary tree that is distinct from the one that led to humans. But these fellow primates consistently astonish researchers with social behavior that seems, well, pretty highly evolved. Marmosets engage in rigorously polite patterns of communication and do not talk over or interrupt each other. Though territorial, they are so inquisitive that they will watch videos of marmosets they do not know and learn from them.
For the second time in history, a human-made object has reached the space between the stars. NASA’s Voyager 2 probe now has exited the heliosphere – the protective bubble of particles and magnetic fields created by the Sun.
One of the leading U.S. forensic experts, who served as the primary DNA specialist prosecutor in O.J. Simpson's murder trial, says Canadian agencies are doing victims a disservice by using a potentially misleading DNA technique, instead of a surer method to identify suspects. But it's a method that does come with some privacy risks.
Global carbon dioxide emissions are expected to hit a record high in 2018, despite urgent calls from climate scientists and international groups such as the United Nations to cut back. Worldwide, fossil fuel use is projected to pump 2.7 percent more CO2 into the atmosphere in 2018 compared with 2017. Last year, such emissions contributed 9.9 gigatons of carbon. The data are presented in the Global Carbon Budget published online December 5 in Earth System Science Data. 2018 marks the second year in a row that the emissions, which fuel global warming, have risen substantially after a lull from 2014 to 2016.
