A Major Breakthrough Could Let Both Same-sex Partners Be Biological Parents To Their Kids

The simple discovery that a piece of wire mesh can stop a flame in its tracks saved the lives of thousands of miners.

This demonstration shows how a simple lamp made of gauze could contain the open candle flames that miners used before 1815. With the safety lamp, any potential explosions would stay contained and never escalate to dangerous levels (although mining remained an extremely dangerous occupation).

Measuring the Life of a Human: What Events Will We Miss?

When compared to the life of the universe, the life of a human only lasts the span of a single blink. So, what won’t we get to see?

One thing we’re always doing as a species is expanding our knowledge of the heavens. We send out probes, robots, satellites, spacecraft, all to map out and add to our ever-expanding picture of what the Universe looks like.

But what if that picture suddenly became smaller? That is exactly what happened when new data from the Planck satellite tightened our previous notions of the observable universe, shrinking its area by 0.7%.

If you’ve never realized, we don’t actually see all of the stars in the Universe. If we did, night time sky would be a whole lot brighter. Instead, we see everything within a particular radius, the particle horizon. Any particle of light emitted outside that particle horizon is too far to have reached us.

So if we want to know just how large the observable universe is, we just have to figure out the distance between us and that particle horizon, right?

As it turns out, not quite.

The universe, specifically spacetime, is continuously expanding, with points in the universe moving further apart. This not only changes the distance between objects but also how fast light is moving in the universe. 

The movement of spacetime has an effect on which photons reach us and can be observed.

So how do you calculate the radius? Back in 2003, scientists came up with an equation that took an event called “the recombination” as a reference point in the universe’s history. They combined that with the rate of the expansion of the universe and several other factors, in the end coming up with a number.

Back in 2003, that number was a radius of 45.66 billion light-years. Now, new data revealed a far more accurate number: 45.34 billion light-years.

“A difference of 320 million light-years might be peanuts on the cosmic scale, but it does make our knowable universe a little bit cozier,” Nick Tomasello from the University of the Sciences in Philadelphia writes over at Medium.

The study has been accepted for publication in an upcoming edition of Advances in Astrophysics.

Hi guys! I was inspired to make this post by all of the messages I’ve gotten from people asking me to either tag or stop posting images of spiders all together. And as someone who used to be absolutely mortified by any 8-legged creature, I can see where you are all coming from!  I used to have a bedroom in the attic, a musky basement, an exotic plant and flower garden, and lots of wood piles. So it’s no wonder that I was confronted with spiders of all shapes and sizes. Ranging from the wolf spider, the brown recluse, cellar spiders, and all kinds of orbweavers. Spiders are incredibly important to our ecosystem, and without them we would suffer. They are incredibly complex and fascinating little creatures that, whether we like it or not, are going to cross our path. What helped me come over my fear the most was simply taking the time to learn about them.

1.) You swallow spiders in your sleep: FALSE. Might as well start with the one we’ve all heard! There would have to be so many unlikely circumstances for this to happen that it’s pretty implausible. Most spider species prefer to stay in their webs, while others hunt no where near humans. Beds don’t offer prey so they likely won’t crawl into them intentionally, unless you have other bugs in your bed for whatever reason. Spiders already could care less about us, they definitely won’t be crawling into a moist, slumbering and snoring human mouth.  2.) Two puncture marks means a spider bite: FALSE. Spiders do have two venom-injecting fangs that they usually use at the same time when biting. However, any spider smaller than a tarantula will leave bites so small that there will be no identifiable separation, if a mark is even left at all. When you have two bites right next to each other, it’s probably from a different bloodsucking insect that has bitten you twice.  3.) Daddy Long Legs have the most powerful venom, but its fangs are too small to bite you: FALSE. This is another wildly accepted urban legend with no fact behind it whatsoever. Depending on where you’re from, you may have a different idea of what a Daddy Long Leg is. To some it is a Harvestman while to others it is a Crane Fly; both have no venom! To others it is a Pholcid House Spider, which does have venom, however it is extremely weak.  4.) You’re always within 3 feet of a spider: FALSE. There’s actually some history behind this one! According to an article from the Burke Museum, it started in 1995 when a famous arachnologist stated, “Wherever you sit as you read these lines, a spider is probably no more than a few yards away.“ Throughout the years this line as been repeated with the distance becoming shorter and shorter. In reality, nobody can really say how far you are from a spider at any time. Just remember that spiders don’t really care about you are are likely to ignore you and go about their business.  5.) Spiders can lay their eggs under human skin through their bites: FALSE. First of all, spiders do not find the human body suitable for egg laying. However there are tons of stories claiming that someone’s “friend” had it occur to them (usually by a brown recluse, which prefer to stay far away from humans as their name suggests). Spiders simply don’t have the ability to somehow transfer their eggs into their venom. 6.) Any spider species can be found anywhere: FALSE. Just like animals and insects, spiders prefer certain climates to thrive. Therefore this myth is completely false. Besides house spiders, many species have very limited ranges. For more information on spiders in your area, a quick Google search will do you much better. 7.) Spiders found in your home are dangerous: FALSE. Spiders are not bloodsuckers. They have no reason to bite humans or your beloved Fluffy. Rod Crawford, the Curator of Arachnids at The Burke Museum, has been handling thousand of spiders for 44 years. He claims to have been bitten a total of 3 times. The spiders that are typically found in homes do not obtain venom powerful enough to do you any harm.  8.) Spiders come indoors in the fall: FALSE. Arachnophobes may not like this, but, the spiders in your house have likely been there the entire time. Outdoor spider species are not adapted to the indoors, and vice versa with house spider species. Very few spiders you see in your home have ever been outdoors.  9.) Tarantulas are dangerous or deadly to humans: FALSE. Hollywood tends to paint tarantulas as evil beasts who actively seek out humans to bite. In reality, tarantulas are common furry pets who are easily handled. Their venom has very low toxicity to humans. Most people who have been bitten don’t report anything besides a quick “ouch”. The most “dangerous” thing about tarantulas is the hair on their abdomens, which they can flick off and spread into the air. Although, this only causes mild skin rashes and irritation to the eyes and nasal passages. 

1.) There are approximately 38,000 known species of spiders (as of February, 2015). Scientists believe there are still many more to be discovered. 2.)  Spiders are vital to the ecosystem. Most of us know that they eat harmful insects, but they also pollinate plants and recycle dead animals and plants back into the Earth. They are also an essential food source to other small mammals, birds, and fish.  3.) Not all spiders spin webs. However, they all have the ability to produce silk.  4.) Web-weaving spiders have claws at the end of each leg. This enables them to move around their webs without getting stuck! 5.) Spiders have blue blood. 6.) Giant trapdoor spiders are considered living fossils. This is because they are very similar to the spiders that lived 300 million years ago! 7. The world’s biggest spider is the Goliath Spider. It can grow up to 11 inches wide with up to 1 inch long fangs! But don’t worry; it only eats frogs, mice, and other small creatures. 8.) Spiders have an exoskeleton. While us humans have bones that are surrounded by our muscles, spiders have their bones on the outside to protect their muscles on the inside. Which kinda make more sense to me. Grasshoppers, lobsters, and cockroaches are just a few that also have exoskeletons.  9.) Spider legs use hydraulic pressure to move. Their muscles are able to pull their legs inward, but not out again. This requires pumping a watery liquid into the legs to move them back out. This is why dead spiders’ legs are curled in.  10.) Spiders sometimes use a line of silk to “fly” through the air. This is called “ballooning”. You probably remember all but three of Charlotte’s babies did this. 11.) Baby spiders are called spiderlings. Pretty adorable.  12.) Males risk being eaten by the females. Similar to insects, female spiders are usually larger. They tend to eat any small creature that comes along, including the males who just wanna get some. The males attempt to avoid this by plucking strands of the female’s webs or doing a little dance (jumping spiders, who knew they could get more adorable).

Now, I know overcoming fears does not come easily to everyone. It took me quite a while! So I’ve put together some ideas that helped me. Just remember that this may not help everyone. If your fear is complicating every day life it may be best to seek help from a professional. 1.) Watch YouTube videos of spider handlers. This, this step right here, was the most important for me. It all started with this video. This owner cared so much about his spider who was having difficulties molting. He took the time to attempt to help her get it off, and showed a huge amount of grief and compassion as it went on. As someone who used to be scared of spiders, this video showed me a different side. This person loved this spider just like I love my cat. I began watching and subscribing to more and more channels, and found that it helped me a lot. Some channels worth looking at are tarantulaguy1796, TarantulaAddict, Jon3800, and Frankus Lee.  2.) Observe live spiders. If you see a spider in your house or outside, take a deep breath and just watch it for a little bit (at a distance, if you’d prefer). Watch its legs and how it moves, its different body parts and what it seems to be doing. Just watch them. They’re not going to jump on you and start gnawing on your arm like a human corn-on-the-cob, I promise.  3.) Visit spider exhibits. Whether it be at an aquarium, zoo, or museum, take the time to take a walk through the insect and arachnid exhibits. There will often be someone there who knows a lot about them who you can talk to. As mentioned before, the more you learn about them, the less scary they become! 4.) Watch someone handle a spider, or handle one on your own! Okay maybe the second one is a big step to take right now. But a lot of spider handlers may let you touch their legs (which are a lot furrier than you’d think!). However, if you’re too afraid, it’s best to watch from a distance for a while or pay close attention to how the handler holds the spider. The first time I held a spider I was pretty scared, but I was more concerned with dropping it or hurting it. I was amazed at how not-creepy it was and I walked away with an awesome experience. Just remember to keep them away from your face and to wash your hands before and after to keep those pesky hairs from irritating you.  5.) Overall, take it slow. If you need to start with pictures, start with pictures. Then gifs. Then videos. Then live spiders. It’s all up to you. In reality, spiders do not want to bother you. They are not these crazy blood-thirsty creatures that Hollywood and myths make them out to be. Educate yourself and remind yourself how amazing and important these little 8-legged guys are!

Kryptos is an encrypted sculpture by the American artist, Jim Sanborn, that is located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the encrypted messages it bears. Of the four messages, three have been solved, with the fourth remaining one of the most famous unsolved codes in the world. The sculpture continues to provide a diversion for cryptanalysts, both amateur and professional, who are attempting to decipher the final section. The sculptor has given clues on several occasions.
