Australia will still be the lucky country when it comes to changes in local climate as a result of climate change if global average surface temperatures reach the 1.5°C or 2°C limit set by the Paris agreement. But in other countries right across the tropics, including close neighbor and major trading partner Indonesia, the heat ...
A new Duke University-led study has found widespread uranium contamination in groundwater from aquifers in 16 Indian states. The main source of the uranium contamination is natural, but human factors, such as groundwater-table decline and nitrate pollution, may be exacerbating the problem. Several studies have linked exposure to uranium in drinking water to chronic kidney ...
The Higgs field is like an endless ocean through which all matter swims. Some particles are like sponges and sop up mass as they lumber along, while others are as sprightly as tiny minnows and dart right through. The Higgs theory is a beautifully simple explanation as to why some particles are massive while others ...
It will be possible to use new astronomical mappings of hundreds of thousands of cosmic voids and galaxy clusters to test Einstein’s theory of relativity by looking for small deviations in gravity at vast distances — a possible explanation for the dark energy that is accelerating the expansion of the universe. This is shown in ...
Thunderstorms in Earth’s upper atmosphere remain something of a mystery. Scientists cannot reach them directly with instruments; they are too high for balloons and too low for weather satellites. Flying through thunderstorms or camping out on mountaintops waiting for one typically ranks low even on an adventurers’ bucket list. An investigation aboard the International Space Station has come ...
An international team of archaeologists has uncovered the earliest example of the equid bit wear in the Near East. The discovery provides the first evidence of the use of a bit (mouthpiece) to control an animal long before the appearance of the horse in the Near East. Evidence of the bridle bit was derived from ...
A new study by geoscientists at the University of Liverpool has identified the temperature at which cooling magma cracks, such as the Giant’s Causeway in Northern Ireland, to form geometric columns. Geometric columns occur in many types of volcanic rocks and form as the rock cools and contracts, resulting in a regular array of polygonal ...
Most parenting programs aim to teach parents how to reduce their children’s disruptive behavior. New research looked at more than 150 studies of these programs, finding differences in what works best according to whether or not children already showed behavior problems. The work was conducted by researchers at the University of Amsterdam, Cardiff University, University ...
Australian researchers have discovered what is thought to be the world’s oldest spider, unlocking key information about the mysterious eight-legged creature. The research, published in the Pacific Conservation Biology Journal, suggests the 43-year-old Giaus Villosus trapdoor matriarch, who recently died during a long-term population study, had outlived the previous world record holder, a 28-year old tarantula found in ...
Across very different cultures — Ghana and the United States — when parents acknowledge adolescents’ perspectives and encourage them to express themselves, the youths have a stronger sense of self-worth, intrinsic motivation, and engagement, and also have less depression. Yet having the latitude to make decisions appears to function differently in the two cultures, with ...
