After the farm fell the group was on the road constantly. You were lucky if you were able to stay in a house for more than two days. This constant traveling was taking its toll on everyone. The group was able to find a warehouse that looked safe enough, but it wasn’t somewhere you could really settle down. Hopefully you would be able to find something permanent soon. Once the warehouse was cleared, Rick said that we should go on a quick run for some food. You were so tired and the last thing you wanted to do was go on a run, but you knew it needed to get done.

You and Daryl were at the front of the group, chuckling at each other. It was rare to see Daryl smiling, let alone laughing and the fact that you were able to do that filled you with happiness. To your surprise Daryl took hold of your hand, making you look up at him and smirk a bit. He gave you a quick wink and squeezed your hand a little. You rested your head against his shoulder for a little while as you kept walking.

“Check it out.” T-dog said to the rest of the group, pointing to you and Daryl. “Hey Maggie do you remember when-” You were about to ask something, but you turned around and saw everyone laughing at you. “What?” You asked, confused. Maggie put her hand up to her mouth to try and hide her smile, then nodded towards your and Daryl’s hands laced together. “(Y/N) and Daryl sitting in a tree K-I-S-S-I-N-G.” Carl sang, with a wide smile on his face. Daryl turned around and narrowed his eyes at Carl, who stopped singing when he noticed the pissed off look on his face. “Aww, that’s so sweet.” Carol said. “What a bunch of fuckin’ infants.” Daryl mumbled under his breath and dropped your hand, walking a little faster ahead of you.

“You guys are the worst.” You said shaking your head at them, but couldn’t help the laugh that escaped. “Oh come on, that was so cute.” Maggie said. Maybe there was a mushy side to your big bad hunter.


Hi guys! Sorry this is so short, I didn’t really know how to finish it. Hope you liked it though!

What would it take to survive in space?

Prolonged space travel takes a severe toll on the human body. As we seriously consider the human species becoming space-faring, a big question stands. Even if we break free from Earth’s orbit and embark on long-duration journeys among the stars, can we adapt to the extreme environments of space?

Without an atmospheric barrier and a magnetic field like Earth’s, most planets and moons are bombarded with dangerous subatomic particles, like ionizing radiation. 

These particles can pass through nearly anything and would cause potentially cancerous DNA damage to space explorers. So, to survive as a species during space travel, we’d have to develop methods to quickly program protective abilities into ourselves. A beta version of these methods is gene therapy, which we can currently use to correct genetic diseases.

Now, what if we could turn the tables on radiation? Human skin produces a pigment called melanin that protects us from the filtered radiation on Earth.

Melanin exists in many forms across species, and some melanin-expressing fungi use the pigment to convert radiation into chemical energy. Instead of trying to shield the human body, or rapidly repair damage, we could potentially engineer humans to adopt and express these fungal, melanin-based energy-harvesting systems. They’d then convert radiation into useful energy while protecting our DNA. This sounds pretty sci-fi, but may actually be achievable with current technology.

@estarmuerto​.

     Almost a year it had taken him. Rubbing noses with those he hated, pretending he was okay with them. They had something he needed, and Reaper needed to prove himself before they’d help him. When he’d finally released his idea to them, they’d foolishly trusted in him. It wasn’t hard to impersonate what Gabriel used to be and express fake regrets. He wanted to go back, to stop it all from happening. Who better than the immortal one? It had taken two months to perfect it, and with select sabotage, Reaper had made sure only one use would come out of it. No one would follow him, nothing would stop him. 

     Anticipation was the emotion that took him over as he stood under the impressive machine. His mask landed on their hopeful faces. Fix this for us, Gabriel. How little they knew. Reaper’s lips curved upward under the mask. He was only going to help Gabriel; he’d make it as it should have been by his standards. In the final moments before the machine sent him off to his destination, he raised his left hand in a slow, mocking wave. 

     The ride was horrible; to the point the wraiths body turned itself into smoke to save itself from trauma. It was with a pained hiss that his form was all but unceremoniously dumped out of whatever wormhole had carried him there and into a storage room, as per the coordinates that had been set. If the timing was correct, he had a few years until the fall hit. As he formed properly, he raised a hand up to his head, grumbling under his breath. Headache. The least of his worries now. Pulling out of his pocket the small holographic map they’d given him as his parting gift, the wraith quickly mapped the way through the vents straight to the office of the man he was there to see; Gabriel Reyes.

     It’s without a single secondary thought that his form shifts, map replaced in the middle of the act. The condensed smoke that he’d become crawling up the wall and into the vent, the tail end of it disappearing as the door to the storage room opened and a few confused agents made their way inside. His approach through the vents was silent, only when he filtered through the vents into the desired office did he make any noise. The second he was through, he formed partially and let himself hit the ground with a soft thud to announce himself as he drew upward to his full height, the shadows forming a solid form. The mask quickly scanned the room before landing on the target. He’d been right; there he was.

      ❛ Gabriel Reyes, in the flesh. It’s my pleasure to finally come face to face with you. I’d ask you refrain from causing a panic. I’ll be gone before anyone else gets here. They’ll never find me, and I’ll keep cycling that routine until you speak to me. So let’s cut to the chase and talk about who I am and why I’m here. Why you really need to care. I promise you, I’m not here to lay a harming finger on you. In fact, I’m here to make sure no one ever does. ❜

What would it take to survive in space? (Part 2)

Prolonged space travel takes a severe toll on the human body. As we seriously consider the human species becoming space-faring, a big question stands. Even if we break free from Earth’s orbit and embark on long-duration journeys among the stars, can we adapt to the extreme environments of space?

Variation in gravitational strength is another challenge for space travelers. Until we develop artificial gravity in a space ship or on another planet, we should assume that astronauts will spend time living in microgravity

On Earth, human bone and muscle custodial cells respond to the stress of gravity’s incessant tugging by renewing old cells in processes known as remodeling and regeneration. But in a microgravity environment like Mars, human bone and muscle cells won’t get these cues, resulting in osteoporosis and muscle atrophy. So, how could we provide an artificial signal for cells to counteract bone and muscle loss?

This is speculative, but biochemically engineered microbes inside our bodies could churn out bone and muscle remodeling signaling factors. Or humans could be genetically engineered to produce more of these signals in the absence of gravity. 

Radiation exposure and microgravity are only two of the many challenges we will encounter in the hostile conditions of space. But if we’re ethically prepared to use them, gene editing and microbial engineering are two flexible tools that could be adapted to many scenarios. In the near future, we may decide to further develop and tune these genetic tools for the harsh realities of space living.

Frost Lost in the Big Sky (Closed)

@kellanvarastrarp

When Loki touched the Casket of Ancient Winters after discovering his true bloodline he had been stripped of his magic. He was suddenly standing in the vault of Asgard with blue skin and red eyes. He tried to turn back, but failed and knew he needed to escape. A Jotun would not be welcomed by the people of Asgard. He ran from the vault and stayed to the shadows as he tried to escape the palace. He quickly made his way to one of his secret pathways to the other realms. The closest one led to a place on Midgard. 

The travel took a toll on him and knocked him out. His body crashing into the soft snow in a clearing of a forest. He was still unconscious as the sun began to set. He was unsure of where he was or who was going to find him.

Prolonged space travel takes a severe toll on the human body. As we seriously consider the human species becoming space-faring, a big question stands. Even if we break free from Earth’s orbit and embark on long-duration journeys among the stars, can we adapt to the extreme environments of space?

This wouldn’t be the first time that humans have adapted to harsh environments and evolved superhuman capabilities. For example, at very high altitudes, the body usually produces extra red blood cells, thickening the blood and impeding its flow. But Himalayans who have lived in the mountains for thousands of years permanently evolved mechanisms to circumvent this process and maintain normal blood flow. Cases like that prove that humans can develop permanent lifesaving traits. But natural adaptation for entire human populations could take tens of thousands of years, so we need scientific advances that help us accelerate human adaptation to single generations.

To thrive as a species during space travel, we’d need to develop methods to quickly program protective abilities into ourselves.

Deep space travel might increase heart risk for astronauts

A new study suggests traveling beyond Earth’s magnetic shield can actually compromise long-term cardiovascular health. Scientists are starting to learn more about the toll space travel takes on the human body. When, earlier this year, astronaut Scott Kelly returned to Earth after nearly a year in space, his vertebrae had expanded and he’d grown 2 inches. In short, microgravity really screws with you.

Twins Spent 30 Days in Bed to Study Benefits of Exercise during Spaceflight

Thanks to prolonged weightlessness, space travel takes a toll on the body — causing loss of bone density, muscle strength and heart function, for example. Microgravity during spaceflight also throws off a person’s balance when he or she returns to Earth — like feeling wobbly before you get your “land legs” back after a boat ride, only longer-lasting. Returning astronauts face a wide range of health issues, including increased risk of fall and fracture due to balance issues, similar to what happens to us all as we age.

Visitors to the International Space Station follow specific exercise protocols to prevent physical deconditioning, but not necessarily balance loss. Alan Hargens, PhD, professor of orthopaedic surgery at UC San Diego School of Medicine, and Timothy Macaulay, an undergraduate student in his lab, hypothesized that treadmill exercise in lower-body negative pressure (LBNP) during microgravity could specifically prevent balance loss (see above diagram).

To test this hypothesis, the team recruited seven pairs of female identical twins and eight pairs of male identical twins. Each participant spent 30 days on strict bed rest, with their bodies tilted head down six degrees to simulate microgravity, as experienced in spaceflight.

Of each set of twins, one exercised and one did not. To exercise, the participant would simulate running on a treadmill while laying down, using a system of pulleys in LBNP. They did this for 40 minutes each day, six days a week. Each session was followed by five minutes of rest in the LBNP chamber, with their feet supported against the vertical treadmill.  

Before and after 30 days, the researchers measured the balance abilities of each twin. One at a time, they stood still or walked along a narrow rail with their eyes open or closed, while the researchers timed how long they stayed on.

In the non-exercising control group, the participants’ average standing rail balance times declined by 42 percent for men and 40 percent for women after the 30 days simulating microgravity in bed. Rail walk distances and times similarly decreased.

But Hargens, Macaulay and team were surprised at what they found in the exercise group: standing rail balance times improved for men (loss attenuated by 63 percent), but not women (loss attenuated by 41 percent, which was not statistically significant). Treadmill exercise within LBNP did not affect rail walk abilities in men or women.

“These results underscore the importance of including both men and women in studies of this type — we would’ve come to a very different conclusion is we hadn’t,” Hargens said. “The study also indicates that exercise programs designed to reduce deconditioning during spaceflight shouldn’t be one-size-fits-all.”
