Body recovered of woman who fell into river

  Body recovered of woman who fell into river REGINA - The body of a Regina woman who fell into the Mad River in British Columbia last month has been recovered. RCMP say the woman — identified by her family as 31-year-old Kristie Lavallee — was found dead in the North Thompson River. RCMP say the woman — identified by her family as 31-year-old Kristie Lavallee — was found dead in the North Thompson River.

After eight years spent recovering lost Moon data from the Apollo missions, scientists report in a new study they’ve solved a decades-old mystery of The missing tapes and the weekly performance logs gave the researchers enough new information to tease out a likely cause for the mysterious heating.

Aldrin, Jr., the lunar module pilot of the first lunar landing mission, stands next to a United States flag July 20, 1969 A decades-old lunar mystery has now been solved thanks to the recovery of once lost data tapes and a massive amount of sleuthing.

The results confirm that inexplicable changes in the moon’s temperatures recorded in the 1970s were not the result of some strange inner heat source, but rather the by-product on astronauts stomping around and stirring up moon dust.

In a study published in April in the Journal of Geophysical Research: Planets, researchers from Texas Tech University used recovered tapes from the 1970s Apollo missions to understand why the moon’s surface appeared to have warmed. These records were taken on the Apollo 15 mission, the fourth mission to land men on the moon in 1971, The Smithsonian reported.

Recover your password. The presence of astronauts on the moon caused an unexpected warming of its subsurface NASA ultimately abandoned the research due to a lack of funding, and only some of the tapes were archived, with the others assumed lost, leaving scientists unable to analyze it further.

A decades-old lunar mystery has now been solved thanks to the recovery of once lost data tapes and a massive amount of sleuthing. Researchers from Texas Tech University used recovered tapes from the 1970s Apollo missions to understand why the Moon ’s surface appeared to have warmed.

The primary purpose of this trip was to observe the moon’s surface through a variety of experiments. This included drilling probes into the moon that sent information back to Earth. Records of the moon’s temperature were taken from 1971-1977 but data from 1974-1977 were lost, Sciencealert reported.

The team was only able to recover less than 10 percent of all the lost tapes, and the information they could recover was poorly degraded. However, they did their best to restore the tapes and were able to fill in some of the gaps with the help of some hardcore science skills. Now, eight years after the tapes were originally discovered, the team have concluded that human activity was the reason for the temperature increases measured on the moon.

Can You Solve This Ice Cream Cone Riddle?

  Can You Solve This Ice Cream Cone Riddle? How much is an ice cream cone worth? In this visual riddle by Budapest-based artist Gergely Dudás (who posts comics on Dudolf.com), the answer requires a little math.The riddle asks you to determine how much an ice cream cone, a scoop of white-colored ice cream (let’s call it vanilla), and a scoop of pink-colored ice cream (let’s call it strawberry) are worth, according to the logic of the puzzle.Stare at the equations for a while, then scroll down for the answer.

All the time since the tapes were recovered , a group of scientists analyzed the lost lunar tapes until they got the answer. The source of the strange warming of the moon in the 1970s was none other than the Apollo astronauts themselves. Mystery of the 40-year-old moon solved .

Through recovering the lost tapes of Apollo moon missions, scientists finally have an answer on why the lunar surface became bizarrely warmer during the 1970s. 40-Year-Old Moon Mystery Solved .

The biggest indication that humans were the cause of the temperature increases on the moon was that the warming was stronger on the surface and faded in measurements taken deeper in the moon. This suggests that the source was not from inside the moon.

It appeared that the astronauts and their rovers stirred up the moon's loose outer surface dirt, exposing darker surface dirt—also known as regolith—that would have otherwise been hidden. Just as you learned to avoid dark shirts in the summer as dark colours absorb heat, the same is true for the moon’s surface. The now-darker dirt absorbed more of the sun’s heat, initially increasing the moon’s temperature.

In addition, photos acquired from the Lunar Reconnaissance Orbiter Camera show that there are dark surface paths on the moon where astronauts have traversed, Sciencealert reported.

“We suggest that, as a result of the astronauts' activities, solar heat intake by the regolith increased slightly on average, and that resulted in the observed warming,” the researchers wrote.

Three missing after boat sinks off Tofino, B.C. .
TOFINO, B.C. - A search is underway in the waters off the west coast of Vancouver Island after a small boat carrying five people went down early Friday. Lt. Melissa Kia with the Joint Rescue Co-ordination Centre in Victoria said the search began around 2 a.m., in waters just south of Tofino. She said the open boat sank without declaring a mayday and the first indication of trouble came from callers to 911. "Those were reporting that calls for help were being heard from the shoreline close to Duffin Cove, off of Tofino," Kia said. The Canadian Coast Guard fast response boat from Tofino was among the first of two vessels and two aircraft assigned to the rescue.
