SPACE TREES
At NASA's Goddard Space Flight Center, there is a sycamore tree, and it seems like any ordinary tree. But what people don't know is that it's from the moon. The Goddard sycamore tree is one of the moon trees, grown from seeds that traveled to space. On the Apollo 14 mission in 1971, astronaut Stuart Roosa had hundreds of seeds packed in his personal kit. Before he was an astronaut, Roosa was a smoke jumper ( wildland firefighter) for the U.S. Forest Service, so he brought the seeds to recognize the agency and help NASA scientists to if microgravity affects plants. The seeds survived the moon microbes and most of them germinated normally. Then, the saplings were planted across the country, but received little recognition. But, later, people were curious about the trees and remembered the achievement.

Danger At Mount Everest
Many climbers think about reaching the top of Mount Everest, the highest place in the world. But, 11 deaths have already been reported this year, even with the advancement of the equipment and weather forecasting systems. It's been the deadliest season since the 2014 icefall that killed 14 Sherpas ( guides that help with gear); it was because of the traffic jam of people wanting to reach the peak. The 2019 Everest climbing season has been shorter due to harsh weather, making it more packed with climbers. The passageway to reach the peak was delayed a few hours and climbers had to wait at elevation more than 26,000 feet. People had died by running out of oxygen or exhaustion. The problem is that more inexperienced climbers are coming to climb the mountain and they are being led by inexperienced operators. The government disagrees, saying that deaths are caused by weather conditions and insufficient supplies; and they will quip the guides with better equipment.

Basking Sharks ARE BACK !!!
Recently in 2019, people on whale watching trips along the Southern California Coast have seen a rare sight, dozens of basking sharks in the water. This was the first time in several decades they have been seen in the area, in large groups. Basking sharks, the world’s second largest fish, can measure up to 30 feet in length and weigh over 10,000 pounds, but they are harmless to humans. They used to be found in large groups in temperate waters in both the Atlantic and Pacific oceans, but almost vanished in the California coast from excessive fishing and killing. It was hard to revive the shark’s population because scientists knew little of them. But it was assumed that because the ocean was changing, that was the reason why the basking sharks came back.

Navy Seal, NOT GUILTY!!!
On Tuesday, a military jury freed Special Operations Chief, Edward Gallagher, of premeditated murder. It was for the killing of a wounded Islamic State captive handed to them for care in 2017. Gallagher’s photo of him holding the dead captive up by the hair and holding a knife in the other hand with the text message,” got him with my hunting knife.” was what prosecuted him for this crime. Five marines and two sailors had to decide whether Gallagher had stabbed the captive or framed by platoon members that want to stop him from being promoted. Testimonies from some navy seals had said that they saw the chief stab the captive in the neck. Defense lawyers said that the photos and text messages were just dark humor. It was later uncovered that when Marine Staff Sergeant Giorgio moved the dead body, he saw no stab wounds on the neck. There was no body evidence and no blood on the knife, so it was assumed other things could have caused the death. In result, he was found not guilty of the Navy’s most well known war cases.
