Marine biologists: Small fish trawling leads to more jellyfish

Marine biologists say they have proof that excessive trawling of small fish species leads to proliferation of jellyfish, a worsening phenomenon whose causes have been unclear. The scientists monitored ecosystems in two ocean zones a thousand kilometres (600 miles) apart, traversed by the same current. One zone was off Namibia,…

Scientists clone extinct frog that gives birth from its mouth

The conclusion was reached by Charles Brown, a University of Tulsa researcher who’s spent the…

Scientists discover earthquakes can create new ‘economic-grade gold deposits’

Solid gold can be deposited in Earth’s crust “almost instantaneously” during earthquakes, said a study published in the journal Nature Geoscience on Sunday. The gold is formed when a tremor splits open a fluid-filled cavity in the Earth’s crust, causing a sudden drop in pressure, according to a team of…

Researchers explore positive social and cognitive effects of video games

Even as videogames come under scrutiny for potential harmful impacts, researchers and developers are touting digital games for positive effects on health, learning and other social goals. The immersive power of games is being used to encourage kids to develop healthy eating, help seniors maintain brain functions and even to…

Scientists excited by discovery of ‘Underground Galapagos’

Diverse underground ecosystems buried deep beneath the Earth’s crust may offer clues to the origins of life on Earth, several recent studies have revealed. Whether it is tiny worms found wriggling in the depths of a South African mine or micro-organisms discovered six kilometers (3.7 miles) under the surface in…

Stonehenge remains a mystery as scientists ask: was it a health spa or a cemetery?

Archaeologists back conflicting theories on Britain’s greatest prehistoric monument It already attracts more than a million visitors a year.
