Scientists pinpoint the exact 'turning point' year when your body’s aging process accelerates

Much like you had a growth spurt, scientists have found an aging spurt.

It’s often assumed that aging is a consistent process where we grow to a certain point and then our bodies begin to wear down at a predictable pace until the inevitable end. However, according to a new study out of China, the average human body has an accelerated leap during the aging process before returning to its normal rate.

According to the researchers at the Chinese Academy of Sciences, aging begins to accelerate at the age of 50. Or, when women are going through menopause and men are starting to love Kirkland jeans. "Based on aging-associated protein changes, we developed tissue-specific proteomic age clocks and characterized organ-level aging trajectories. Temporal analysis revealed an aging inflection around age 50, with blood vessels being a tissue that ages early and is markedly susceptible to aging," the team led by scientists from the Chinese Academy of Sciences wrote in the journal Cell.

Why does aging accelerate at 50?

To put it in layman’s terms: By looking at how specific body proteins change as we age, researchers made special tools to measure how old organs vary in biological age. They found that around age 50, the aging process accelerates, and blood vessels start aging earlier than other organs.

To learn more about the aging princess, the researchers collected tissue samples from 76 organ donors between the ages of 14 and 68 who had died of traumatic brain injury. The samples were taken from seven of the body’s systems: cardiovascular (heart and aorta), digestive (liver, pancreas, and intestine), immune (spleen and lymph node), endocrine (adrenal gland and white adipose), respiratory (lung), integumentary (skin), and musculoskeletal (muscle).

The body’s aging process speeds up between 45 and 55

After studying the proteins found in different systems, the researchers found that the most stark changes in the aging process occurred between the ages of 45 and 55. The greatest amount of changes happened in the aorta, the body’s main artery that runs that passes over the heart from the left ventricle and runs down the front of the backbone.

The researchers hope that their work will eventually lead to mapping of the entire body, where we can better understand the process on an organ-by-organ basis. That could lead to one day having different biological ages for various body parts based on proteins and lifestyle choices. One could have a liver that's 35 and an aorta in its 50s. "These insights may facilitate the development of targeted interventions for aging and age-related diseases, paving the way to improve the health of older adults," the authors concluded.

It may be a bit jarring for younger people to know that just like they may have enjoyed a growth spurt while in high school, they can also look forward to an aging spurt that happens at 50. The good news is that if you are past 55, then you are likely to be able to look forward to a phase where the aging process slows down a bit.

Keep flies out of your house and trash this summer with these tricks

Summertime is a time for outdoor activities: dinner on the grill, days at the beach, and water balloon fights in the front yard. But with warmer weather and more frequent trips outdoors comes a familiar summer annoyance–flies. No matter how careful you try to be, flies seem to always make their way into homes, trash cans, and cars. Flies love to buzz around wherever there's food and to clumsily bump into people, windows, and doors when they're getting shooed out of the house.

Ugly, sticky fly strips can help but accidentally walking into one is about as pleasant a wet sock sliding down your heel after an amusement park water ride. But there may be an easier way that doesn't require a rolled up newspaper and mental calculation on the velocity in which you'd need to swat a fly mid-air. Turns out you don't need an old fashioned fly swatter or harsh chemicals because there are pesticide-free ways to keep the pesky insects away.

Let's face it, while adult flies are annoying, it's the larvae hatching in your trash can that makes you want to jump out of your skin. Successfully shooing the adults away will greatly reduce the likelihood of seeing their creepy crawly babies. One of the more time consuming but cost effective ways is to keep your trash cans clean and dry. Flies are attracted to decaying foods so tossing food into the trash quickly becomes a calling card for the unwelcome guests. You can also try:

1. Vinegar solution and baking soda clears flies hovering around outside trash bins

There's no rule that says you can't use the two products for your inside trash can, so do so if you're feeling ambitious. You may be thinking vinegar and baking soda will turn your trash can into a school science fair worthy volcanic explosion, but we aren't mixing the two. If you notice flies having family reunions around your trash can, it means they smell something deliciously gross in the making.

Grab an empty spray bottle, fill it up with water and some white vinegar, let it sit for 20 minutes and then use it to clean the trash can. After the solution dries, sprinkle around two cups of baking soda into the trash can and let it sit to neutralize the smells. You can add more baking soda every time you take out the trash to keep the odors from returning. To be extra cautious, use newspapers to line the bottom of your trashcan to help keep the moisture down, since flies love moisture and heat.

2. Certain essential oils makes flies find somewhere else to visit

There was a point in time where essential oils were suggested for just about everything with very little direction for use. Cough? Essential oils. Stomach bug? Essential oils. Exorcising demons? You've got it, essential oils. Ok, maybe that last one is a bit of an exaggeration, but it certainly seemed like essential oils were the cure-all for several years, but maybe those crunchy oil moms were onto something because it turns out essential oils can help deter flies from finding your home inviting.

Lavender, eucalyptus, bay leaves, cinnamon, peppermint, and clove oil can all be used to deter flies. You can add a few drops of the oil of your choice to cotton balls or pieces of cloth and place them in inconspicuous areas around the house. These oils can also be dropped into a spray bottle filled with water to spray around door frames, windows, sinks and trash cans. Clove oil specifically can be sprayed directly onto flies as a natural insecticide according to Lomi.

Note: certain essential oils shouldn't be used around certain pets and sensitive people. Here's more information on it, but also double check with your veterinarian about which oils are safe to use.

3. Grab a couple of fans to help circulate cool air and keep flies from buzzing around

Did you know that flies aren't strong flyers? Kind of weird since "fly" is literally their whole name. It's sort of like someone saying bumble bees aren't great at bumbling around. You'd think it's made up but it's not. Fly wings are very thin and fragile and, in comparison to the weight of your average housefly, it makes sense that a slightly strong gust of wind would be inconvenient for them.

This is terrible news for flies but fantastic news for humans who prefer a fly free environment that's also free of heat. During the warmer months, having a few tower fans to keep discretely near doors can cause enough of a flying hazard to keep flies searching for a more suitable environment. Kind of like how some grocery stores have that constant gust of air at the entrance of their stores. Feels good to people on a warm day but for practicality purposes, it keeps flying insects out. Replicate that at home for a fly-free summer.

Of course, if all else fails or you simply don't want to go with a more natural solution, there's always chemical sprays you can pick up at your local grocery store.

Man builds small puddle in forest. It attracts an astounding scene.

Animals, much like people, need the basics of survival in order to thrive: food, water, shelter from harsh elements, and some form of companionship. It's not uncommon to see wild animals and not think much about us having similar basic needs, but I also haven't met a person yet who doesn't internally squeal with delight at the sight of two otters holding hands while floating down a river.

Point being, animals and humans have similar needs and sometimes wants, though it's unclear if the animals this forest explorer encounters need access to water or if they simply want a swimming hole. In an adorable video uploaded to social media, a man exploring a forest in Brazil decides to dig a small hole in the ground and fill it with water. This wasn't just a hole that would eventually disappear when the water absorbed into the ground.

The unnamed man fits the hole with what looks like a black plastic tarp that goes in the bottom of a pond, holding it in place with large stones. He then sets up a camera on a nearby stake he places in the ground to film what happens after he leaves. The results make it difficult to contain a smile. It seems almost immediately after the sun rises there's a menagerie of different animals coming to check out the new watering hole.

First, two green birds that look like either parakeets or Brazilian parrots arrive. Then, another larger bird comes by. In the time-lapsed video, birds dominated the manmade puddle of fresh water. They drank, played, flapped around in the water, just having the best bird time before a new animal shows up. This time it's a pair of adorable baby jaguarundi who are quickly joined by two more slightly larger cubs, all drinking from the hole.

At one point, a giant lizard decided that the new watering hole made a good pool so he laid his entire body in it. It's not clear if any of the animals wanted a drink while the lizard was having a rest, but the next shot is of a large bird looking directly at the camera as if it were tattling. Commenters loved the fun video of animals checking out the little makeshift pond in the middle of the forest.

"The biodiversity is truly staggering. The baby mountain lions were the cutest. Also the disrespect of the monitor lizard just lying in it was hilarious," one person says.

"All of those animals having a drink, a bath, some fun... except that one bird, face in the camera, going 'It's a trap!'" someone jokes.

"I don't get anything anywhere near as cool as these beasts, but setting up a big bird bath + another one at ground level right near my study window was the best investment I've ever made in my yard. Daily I get at least 20 different birds of 4-5 different species drop by for a drink/bath along with a few lizards, and at night there's everything from possums to koalas having a sip," another says.

Someone else comments on the beauty of it all, saying, "It’s kind of incredible just how many diverse critters live out in the forests of Brazil."

The way the animals responded to the pond makes it seem like they've been waiting around their whole lives for someone to build one. No squabbling or one species trying to stake claim—they all took turns enjoying a drink or playing. It's quite sweet how seemingly cooperative they all were. They'll get good use from that small watering hole for a while thanks to a curious human with a camera.

The ocean covers more than 70 percent of our planet—yet there’s so much about it that we don’t yet know. Experts, in fact, believe we’ve only explored about five percent of the ocean so far—meaning that most of it remains completely unseen and undiscovered.

What we do know, however, is that the ocean is truly wise. Not only does it sustain all human and animal life on the planet, the creatures under the sea continue to give scientists insight that can transform human lives as well (just read about the amazing axolotl below to see what we mean).

A happy ocean makes for happy, healthy human beings (not to mention a healthy planet)—so this summer we’re helping our friends at Ocean Wise spread the word that no action is too small—holding a cleanup on a local shoreline, for instance. Learning about our ocean and all its wonders is another step anyone can take for conservation, so buckle in and prepare for a tidal wave of info that will blow your mind.

1. Playing music—specifically, recordings of healthy reef soundscapes—can help grow coral reef populations.

Healthy coral reef populations are filled with diverse sounds, thanks to the fish, snapping shrimp, and other marine life that live there. Scientists have found that playing recorded sounds of healthy reefs actually attract coral larvae, since the sounds indicate a healthy, vibrant habitat. Using this knowledge, scientists have taken recorded reef sounds, played them near degraded reefs, and in doing so, have increased the settlement rates of coral larvae, helping the coral reefs regenerate.

2. Dolphins like to party with pufferfish.

How’s this for a good time? Dolphins, particularly younger ones, have been known to seek out pufferfish to play games with them, chewing on them and passing them back and forth between each other like a hacky sack. Not only is this entertainment for the dolphins, scientists theorize that they may intentionally be trying to get the pufferfish to give off a neurotoxin called tetrodotoxin (TTX)–which is a chemical they release when threatened. This chemical is highly toxic in large doses–but in small quantities, experts think that it might induce a mild, pleasurable effect in the dolphins, similar to a narcotic. Party on.

3. Male humpback whales are total crooners.

All humpback whales can vocalize, but male humpback whales actually sing.

During mating season, scientists have observed male humpback whales making sounds that are distinctly different from other humpback calls. Unlike other sounds, these songs have a clear structure, and use small, repetitive “phrases” organized in a specific sequence—in the same way humans sing different verses during a song. Even more amazing? Male humpbacks all sing the same song together in “choruses,” in sessions that last from five minutes to several hours.

4. Axolotls have superpowers (and scientists think it could benefit humans one day).

Among biologists, axolotls are known for their ability to regrow lost or damaged tissue. When an adult axolotl loses a limb, they can actually grow it back in just a few months time, thanks to a substance they produce called retinoic acid, which plays a large role in regenerating skin cells. (If the name sounds familiar, it’s because retinoic acid is a derivative of Vitamin A, and it’s commonly found in skin creams.) While we already know that retinoic can make our skin look fabulous, scientists are currently studying whether it could someday help human limbs regrow, similar to the axolotl’s.

5. A healthy ocean can help reverse climate change

The ocean generates half of the oxygen we breathe and absorbs nearly a third of the world’s carbon emissions. Phytoplankton, the microscopic algae that float near the ocean’s surface, are a big part of the reason why. But there’s another unsung hero—kelp. Unlike phytoplankton, kelp are large seaweeds that grow in dense underwater forests along coastlines, absorbing CO2 and supporting ecosystems. Ocean Wise is helping bring back these powerful carbon sinks one kelp forest at a time.
