Gadget lovers or the entire world has been eyeing Apple’s new handsets i.e. iPhone 6S and iPhone 6S Plus and now the tech giant has finally unveiled the new iPhones and has finally made it available to public.

This year’s release is the second generation to feature the 4.7-in and 5.5-in displays. As per gadget experts these new handsets are slightly larger and heavier, but look very similar to their predecessors.

This year the company has launched a new color for the iPhones i.e. the ‘Rose Gold’ color. Apart from their appearance, the iPhone 6S models are very different from the once previously launched by the company.

A "walkabout" survey of "Marathon Valley” is being conducted by NASA's Mars Exploration Rover Opportunity. In "Marathon Valley", the rover's operators are looking forward to use the vehicle through the impending Martian winter, and ahead of it, in order to analyze the context for outcrops bearing clay minerals.

A scene mainly showing a summit called "Hinners Point", forming part of northern edge of the valley, has been captured by panoramic camera of the rover. The image is also showing a part of the valley floor with swirling reddish zones, which is the main topic of the study.

The highest resolution images of Pluto ever captured have been released by NASA. The images have been taken by the New Horizons probe in its flyby of the dwarf planet in July. The most detailed color map of the dwarf planet is seen in the images.

According to William McKinnon, New Horizons Geology, Geophysics and Imaging (GGI) team deputy lead from Washington University in St. Louis, "It's a unique and perplexing landscape stretching over hundreds of miles. It looks more like tree bark or dragon scales than geology. This'll really take time to figure out; maybe it's some combination of internal tectonic forces and ice sublimation driven by Pluto's faint sunlight".

Beach goers are tackling Red Tide on South Padre Island. According to Jason Straub, a meteorologist with the National Weather Service in Brownsville, the tide could be showing its effects a month prior to removal of the toxic algae bloom from the area.

According to him, “It’s going to take a significant north flow or a significant south flow to push this either north or south. So it’s pretty much in place for the next several days”.However, he said, “It’s going to take probably a month for it to get out of here”. And the last three have been similar to this.

On Thursday, the US Fish and Wildlife Service said that nearly 3 dozen young walruses have been found dead previous week on the beach near Point Lay. The Service said that there seems to be no foul play in their death.

Fish and Wildlife Service spokeswoman Andrea Medeiros said that a researcher with the US Geological Survey has discovered the bodies when he was conducting unrelated walrus study and captured pictures.

He said that the potential disturbance caused to walrus by artificial platforms is likely to outweigh the advantages. Heads and tusks were missing in some walrus.

The investigation of 25 walruses found dead and reported shot at Cape Lisburne nearly 100 miles southwest of Point Lay, has been under supervision of the US Attorney in Alaska.

Earlier marine biologists assumed that fish did not have the brain power to co-operate with other fish, but now, according to a new research some fish pairings look out for each other while searching for food.

SMH wrote that scientists have found some species of birds and mammals helping out one another, but they used to think that such a behavior needed a highly developed brain and social skills, which is sadly not possessed by fish.

But, ARC Centre of Excellence for Coral Reef Studies has observed rabbitfish in Queensland guarding each other as their mate searched for food. According to researcher Dr Simon Brandl, the fish were strict regarding co-ordinating their watchful behavior.
