Patients are getting larger and perhaps even dangerous doses of radiation from the growing number of advanced medical-imaging tests being ordered by doctors, a new study says. Researchers at the University of California, San Francisco, analyzed data from millions of patients who received medical treatment between 1996 and 2010. They found that the number of patients who underwent CT scans […]

The species of bacteria that dominate our guts may strongly affect whether we’re thin or fat. Researchers at Washington University collected samples of gut bacteria from pairs of twins in which one was obese and the other thin. Then they transplanted the bacteria into mice. The mice that received the bacteria from the obese twins became obese; the mice that […]

The Antikythera Mechanism: The original mechanism apparently came out of the Mediterranean as a single encrusted piece. Soon afterward it fractured into three major pieces. Other small pieces have broken off in the interim from cleaning and handling, and still others were found on the sea floor by the Cousteau expedition. Other fragments may still be in storage, undiscovered […]

Earthquakes are the result shifting plates in the crust of Earth. When there is frictional stress building of the plates it causes failure at a fault line an earthquake happens. The shaking of the ground happens when the energy is released, and waves radiate. Research has found that they predict where major seismic activity may happen, but they cannot forecast […]

Massive icebergs more than 18km long give Giant boost for south polar waters by feeding vital nutrients into the Southern Ocean and helping to increase its carbon storage capacity. LONDON, January, 2016 – British scientists have identified the monsters that fertilize the Southern Ocean and help remove carbon dioxide from the atmosphere. Giant icebergs drifting northwards could be responsible for storing up […]

Mysterious plumes of gas rising more than 150 miles above the surface of Mars have left scientists confounded. On two occasions in the spring of 2012, amateur astronomers spotted a cloud developing on the surface of the Red Planet. The plumes, which spanned about 600 miles in diameter and changed shape constantly, appeared within a few hours and remained […]

“Knowing what a chicken looks like and what all the chickens before it looked like doesn’t help us to understand the egg,” says Taras Gerya. The ETH Professor of Geophysics uses this metaphor to address plate tectonics and the early history of the Earth. The Earth’s lithosphere is divided into several plates that are in constant motion, and today’s geologists […]
