Local officials and scientists are keeping a close watch on a large chunk of fiberglass just off the Oregon coast that seems to be from a boat that might be part of the tsunami debris from the Japanese earthquake of 2011.

According to Chris Havel, a spokesman for the Oregon Parks and Recreation Department (OPRD), the object was spotted just west of Ona Beach near Seal Rock and Newport and it is about 30 feet long.

Havel said that a team of state agencies are getting ready in order to retrieve the debris from the ocean. Some fish native to waters of Japan is found living on the object, involving one still alive. As per the officials, there were also a variety of yellowtail jack fish, and other sea life that clings to boats and debris.

A new study led by the National Center for Atmospheric Research (NCAR) has revealed that the sun's seasonal changes have an impact on the Earth.

According to researchers, the sun undergoes a type of seasonal variability with its activity waxing and waning over the course of nearly two years. This leads to sometimes amplification and sometimes weakening of the solar storms that can buffet the Earth's atmosphere.

The seasonal variations come from changes in the bands of strong magnetic fields in each solar hemisphere. These bands also help to shape the approximately 11-year solar cycle that lasts about 22 years.

According to observations by the research team, the overlapping bands are intensified by the rotation of the Sun's deep interior.

The National Aeronautics and Space Administration (NASA) and International Business Machines (IBM) have collaborated for the fourth Annual International Space Apps Challenge, or Hackathon. Both the United States space agency and the computer hardware company will encourage scientists, engineers, programmers and educators to work on applications that could assist the space program of NASA and improve connectivity with people.

The Hackathon was started by NASA to search for ideas from sources outside the space agency. In the event, many programmers work together on software projects. The event takes place for a few days every year. It promotes creation of a number of unique of programs that can help the space agency.

1903, researchers said that there was not enough evidence which could prove that Brontosaurus ever existed. But a new study suggested that Brontosaurus, which was once the most famous dinosaurs, should be reinstated as their genus among dinosaurs. According to the study, the animal was real and lived on earth a long time ago.

More than a century ago, researchers found that anatomical differences between Brontosaurus and Apatosaurus were minor and the two could not be combined in a single genus. That time, the researchers decided that Apatosaurus will be considered as the older classification, and the Brontosaurus name was nullified by the researchers.

According to experts, thousands of goldfish have invaded Colorado Lake. The authorities believe that someone went to Colorado Lake and dumped a few gold fish in the water few years back and now they have multiplied into thousands.

Presently, the Colorado Parks and Wildlife rangers are putting efforts to understand what to do with the said fish population. According to experts, it was really shocking to see the fast growth in goldfish population. The problem has been recognized by Jennifer Churchill, a spokeswoman for Colorado Parks and Wildlife (CPW).

According to Churchill, it's really a serious problem out there. There are minimum 4,000 gold fish in the Colorado Lake and they can do real damage.

It was long believed that without the use of some kind of auxiliary power, it's not possible to develop devices that help people walk. However, a small, wearable addition to ordinary shoes has refuted the belief, thanks to US scientists at Carnegie Mellon University and the University of North Carolina. The device has brilliant efficacy to reduce the burden on the calf muscle and enables a person to walk with ease.

Easy walking is believed to help keep people on their feet longer, which offers substantial health benefits. Biomedical engineers Steven Collins and Greg Sawicki analyzed the human walk, which in turn helped them understand that ankles and calves of human beings perform motions similar to a spring coupled with a clutch that intermittently stores and releases energy.
