Disintegrating Alien Planet Has Comet-Like Tail

A potential alien planet that is so close to its parent star that it appears to be disintegrating from the scorching heat was recently found by a team of astronomers. The planetary candidate is only slightly larger than the planet Mercury, and researchers estimate that it is shedding so much material that it could completely disintegrate within 100 million years.

Astronomers at NASA and the Massachusetts Institute of Technology (MIT) detected the tiny planet, which is located roughly 1,500 light-years away, using data from the planet-hunting Kepler mission. As the possible planet evaporates, researchers theorize that it is followed by a trail of dust and debris, similar to the tail of a comet.

The dusty planet circles its host star once every 15 hours, which indicates that the star, named KIC 12557548, likely heats the planet to blistering temperatures of about 3,600 degrees Fahrenheit (1,982 degrees Celsius). The researchers hypothesize that under these conditions, the Read more…

Climate change causing increase in extreme weather in South Pacific

An international study led by CSIRO oceanographer Dr Wenju Cai has identified that global warming is causing shifts in the rain band of the South Pacific Convergence Zone causing an increase in extreme weather across the island nation states of the South Pacific. The result of the movement causes drought and higher prevalence of forest fire in some areas while other islands experience extreme floods and increased frequency of tropical cyclones.

“Due to its strong rainfall gradient, a small displacement in the [South Pacific Convergence Zone] SPCZ’s position causes drastic changes to hydroclimatic conditions and the frequency of extreme weather events such as droughts, floods and tropical cyclones experienced by vulnerable island countries in the region.” says the paper.

The South Pacific Convergence Zone is the important rainband that stretches from the equatorial western Pacific southeastward toward French Polynesia.  When the rainband moves northward, extreme climate events are induced. “Here we show that greenhouse warming Read more…

Minority Report: Fiction Has Become Reality

“The Internet is watching us now. If they want to. They can see what sites you visit. In the future, television will be watching us, and customizing itself to what it knows about us. The thrilling thing is, that will make us feel we’re part of the medium. The scary thing is, we’ll lose our right to privacy. An ad will appear in the air around us, talking directly to us.”—Steven Spielberg

It was a mere ten years ago that Steven Spielberg’s action film Minority Report, based on a short story by Philip K. Dick, offered movie audiences a special effect-laden techno-vision of a futuristic world in which the government is all-seeing, all-knowing and all-powerful. And if you dare to step out of line, dark-clad police SWAT teams will bring you under control.

The year is 2054. The place is Washington, DC. Working in a city in which there has been no murder committed in six years—due in large part to his efforts combining widespread surveillance with behavior prediction technologies—John Anderton (played by Tom Cruise), Chief of the Department of Pre-Crime in Washington, DC, uses precognitive technology to capture would-be criminals before they can do any damage—that is, to prevent crimes before they happen. Unfortunately for Anderton, the technology, which proves to be fallible, identifies him as the next would-be criminal, and he flees. In the ensuing chase, Anderton finds himself not only attempting to prove his innocence but forced to take drastic measures in order to avoid capture in a surveillance state that uses biometric data and sophisticated computer networks to track its citizens.

Seemingly taking its cue from science fiction, technology has moved so Read more…

Op-Ed: Should schools monitor students with ‘spychips’ in student IDs?

Schools have been tracking student attendance for some time,  but the methods of how students are tracked has significantly evolved over the  decades. Currently, using “spychips” in schools appears to be an issue that  keeps emerging its controversial head.

These chips, which integrate RFID technology, are embedded in  student ID cards.

Technology is available as an easy  solution, but is this really the direction society wants to go?

Schools look to “spychips” for  student ID cards

The issue of using RFID technology to  track students has emerged many times over the past several years. Recently, Digital Journal reported a story where  parents and students protestedin San Antonio, Texas after the Northside ISD  school district decided to test pilot RFID student ID cards in two of its  schools.

The student tracking ID card issue in  Read more…

Original Story: A powerful 7.6 magnitude earthquake struck on the west coast of Costa Rica on Wednesday, according to the United States Geological Survey. The epicenter was 38 miles south-southeast of Liberia, Costa Rica at a depth of 25 miles.

According to a statement from the Pacific Tsunami Warning Center, a tsunami warning was in effect for Costa Rica, Panama, Nicaragua, El Salvador, Honduras, Mexico, Colombia, Ecuador, Guatemala and Peru.

A tsunami watch was also in effect for Chile.

The tsunami watch that was issued for the entire Caribbean region was later canceled because it was inadvertently sent by mistake. No tsunami watch is in effect for the Caribbean Sea region.

A later statement said that an evaluation of the Pacific wide tsunami threat was underway and there is a possibility that Hawaii could be elevated to a watch or warning status.

Earthquakes of this size have the potential to create a widespread destructive tsunami that can affect coastlines near the epicenter within minutes and more distant coastlines within hours, but it is not known if one was generated.

According to ABC news, in the coastal town of Nosara in northwest Costa Rica, trees shook violently and light posts swayed. Teachers chased primary school students outside. There were no reports of major damage at this time.
