Karachi, Pakistan Nuclear plants at risk: Pakistani activists are seeking to block the construction of two nuclear power plants in an earthquake-prone, coastal area that is vulnerable to tsunamis. The Chinese are building the two reactors—using an experimental design—less than 20 miles from the sprawling city of Karachi, where 20 million people would be at risk should a reactor meltdown […]

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 […]

Meet “Pepper,” said Richard Lawler in Engadget.com. Japanese telecom firm SoftBank unveiled a new, robot last week that it claims “can recognize human emotion” thanks to technology that allows it to “communicate through emotion, speech, or body language.” Pepper is also equipped with microphones and proximity sensors, and will feature upgradable software, allowing users to install apps and updates to […]

Researchers have identified a new mechanism that drives the development of form and structure, through the observation of artificial materials that shape-shift through a wide variety of forms which are as complex as those seen in nature. It’s curious to observe such life-like behavior in a non-living thing – in many cases, artificial objects can look more ‘alive’ than living […]

Scientists have long laughed at astrology’s underlying premise—that celestial events can influence human emotions and behavior. But a series of new studies has produced evidence that at least one kind of astronomical event—solar flares—may, in fact, affect human beings. Periodically, the sun erupts with large storms that hurl waves of electromagnetically charged particles into space, altering Earth’s own magnetic field. […]

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 […]

What is hail or a hailstone? Hail is a form of precipitation that occurs when updrafts in thunderstorms carry raindrops upward into extremely cold areas of the atmosphere where they freeze into balls of ice. Hail can damage aircraft, homes and cars, and can be deadly to livestock and people. How does hail form? Hailstones grow by colliding with supercooled […]

The rover Opportunity has been roaming over the planet Mars since January 2004 and traveled over 28 miles. It has sent back 225,000 photos of the planets surface. The information from the rover has told us that the winter is twice as long as Earth’s winters. Since it is longer than Earths winters the scientists didn’t expect the rover to […]

Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

Like many human families, killer whales often rely on the wisdom of matriarchs to help them endure hardships and thrive, new research has found. Male orcas usually live for about 50 years, but females often survive well into their 90s, making them one of the few mammalsthat live for decades after they stop reproducing. Marine scientists studied the behavior […]
