The number of people getting colored hair has been steadily increasing over the last several years, and there are now more than 60 million people in the U.S. who have colored their hair. This trend is a chance to continue into 2022, with a projected increase in the number of people getting colored hair by 4%. Assuming you’ve never cherished drawn-out styling meetings, we have some *really* uplifting news. The best hair trend for 2022 are tied in with carrying on with your most low-upkeep life — and we entirely support the carry-up and-go development with layered hairstyles that trim down on styling time to restoring ’90s embellishments (seeing you, hook cuts) that hot sideline apparatuses, the current year’s top looks can be characterized as straightforward and straightforward to accomplish. Everything unquestionably revolves around embracing your regular hair surface and amping up hair wellbeing — while as yet looking stylish.

The latest hair trend for 2022 is… short hair.

If you’ve been thinking about cutting your locks but haven’t been sure how to do it, we’re here to help!Short hair has been making waves in the beauty industry for years now, and we’re here to tell you why it’s worth trying out. Ready?

 Reasons Why You Should Have Short Hair In 2022

1. It’s an easy way to update your look and make a statement. You can go from long and flowing to sleek and chic with just one snip of the scissors—and it’ll only take five minutes or less!
2. Short hair is easier to manage than long hair, which means less time spent styling and max time getting on with your day.
3. Short hair also looks great on everyone, no matter your face shape or natural coloring—so there’s never a wrong time for a trim!
4. Short hair is super versatile, try braiding it up into an updo or wrapping it up in a bun for a long time out with friends; wear it down with waves or curls; tie it back in a ponytail when you’re working out at the gym;

Hand-Crafted Haircut

A new wave of barbershops has emerged to meet this demand, offering customers the chance to experience what it’s like to be supported and treated like royalty in a setting that looks more like an art gallery than a barbershop. These shops offer high-end beverages, luxurious shampoo and conditioner, and personalized service that goes above and beyond your typical haircut.

The best part? They’re affordable! The average cost of a new haircut at one of these barbershops is only $25—which means it’s easier than ever to feel like royalty without having to break the bank.

Moreover, you’ve probably heard about the latest hair trend sweeping the nation: the “lob.” A lob is a long bob, typically with some layers to soften it up. It’s been popular for years now, and we predict that in 2022 it will be even more popular than ever.

The lob is excellent for women who want to keep their hair long and don’t want to do much with it. It’s also easy to style and looks great on everyone—you can wear it straight, curly, or wavy. And since it’s not too long, you don’t have to worry about getting it cut every six months as you might with a traditional bob or shoulder-length cut!

ATLANTA—Georgia State University anthropologist Dr. Jeffrey Glover grew up in metro Atlanta, but speaking to him, it sounds like his heart is in Quintana Roo. This part of Mexico’s Yucatán Peninsula has been the home base for an expansive research project spanning more than 10 years. His research there with Dr. Dominique Rissolo, a maritime archaeologist at

UC San Diego’s Qualcomm Institute, has uncovered thousands of artifacts that help them shed new light on the ancient Maya people who lived along this stretch of coast.

Glover and Rissolo are working with an interdisciplinary and international team of researchers to uncover new insights about the dynamic interplay between social and natural processes that shaped life for these ancient, Maya people over the last 3,000 years. The team has just released a new article in the Journal of Island and Coastal Archaeology summarizing their findings to date.

“The Proyecto Costa Escondida,” which translates into English as the ‘hidden coast’ project, has focused on the ancient Maya port sites of Vista Alegre and Conil.

“We chose the project name because, the coast is literally hidden behind mangroves. We’ve canoed the coastline and you’ve really got to snake back to get to the site,” Glover said. “But at the same time, and more importantly, this region has been hidden from scholarship—there just hadn’t been a lot of work done there until we arrived.”

To date, the work has produced a wealth of knowledge about maritime Maya civilization since 800 BCE (Before Common Era). Glover, an associate professor of Anthropology, is using an historical ecology framework to better understand the dynamic relationship between humans and the environment at the ancient Maya port sites of Vista Alegre and Conil.

“This is about how people respond to change,” said Dr. John Yellen, program director for archeology at the U.S. National Science Foundation, which helped fund the research. “Through the lens of historical ecology, this broad team of researchers has shown how Maya adapted over centuries to a wide range of environmental changes. This insight into one society’s long-term adaptation to coastal environments provides a fruitful model for studying such interactions across many cultures.”

This region lies along Yucatan’s north coast, some hours from popular tourist attractions like Cancun and well-known archaeological sites like Chichen Itza and Tulum.

“What’s remarkable about our study area is that it represents one of the least developed coastlines on the northern Yucatan Peninsula,” said Rissolo, who was recently featured in a video series about the Maritime Maya. “When trying to understand the ancient maritime cultural landscape of the so-called ‘Riviera Maya,’ for example, your perspective is obscured by all-inclusive resorts, golf courses and theme parks. The shores of the Laguna Holbox, on the other hand, are still largely wild and offer a more unobstructed view into the region’s past.”

The site of Vista Alegre is a small island surrounded by mangroves that lies along the southern shore of the Holbox Lagoon (also called Conil or Yalahau Lagoon). Glover describes Vista Alegre as what was probably once a small, bustling port. Here, they’ve discovered and recorded as many as 40 rock-filled platforms that served as the foundation for perishable pole and thatch buildings. The largest is a pyramidal structure that stands about 13 meters—or nearly 43 feet—tall. Glover believes this probably served as a temple and a lookout where the site’s inhabitants could see if anyone was approaching by sea. Conil, on the other hand, is a much more expansive site located beneath the modern town of Chiquila and was encountered by early Spanish conquistadors who described it as a town of 5,000 houses.

Researchers have identified tens of thousands of artifacts and ecofacts (animal and plant remains that speak to past diets), which have helped improve our understanding of how the landscape has changed over time, how the people lived, and how they dealt with challenges not unlike those faced by people today, such as: rising sea levels and changing political and economic systems. “We are coordinating and synthesizing all the different datasets that we have, which gives us a wider-angle picture,” Glover said.

The project, which has been funded by the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA), combines traditional archaeological techniques (think digging with a small hand trowel or shovel) with new, high-tech practices for land and sea. Glover says it is a matter of making the most out of the materials at hand.

“Archaeology requires a broad knowledge of the latest scientific techniques mixed with a strong reliance on ‘MacGyvering,’ Glover said. “We often utilize rustic equipment combined with high-tech tools. On any given day, we might find ourselves in a small dinghy borrowed from the local community out of which we are running marine geophysical survey equipment or pounding PVC tubes into the sediments with a homemade fencepost driver.”

The complex work of marine geoarchaeology was spearheaded by Dr. Beverly Goodman-Tchernov and Dr. Roy Jaijel of the University of Haifa in Israel. The core samples include sediment from the coastline and give researchers a better idea of how the coastline has changed over time by looking at a host of different datasets. In particular, the remains of tiny creatures (foraminifera) are preserved in the cores. These creatures lived in very specific environments, so by finding certain species of foraminifera, the team can reconstruct what the coastal environment was like. Instead of being hidden as it is today, Vista Alegre was most likely once more open and purposely built on a peninsula that jutted into the lagoon making it a more obvious destination for ancient canoe-based traders.

Along with paleo-coastline reconstruction, Dr. Patricia Beddows of Northwestern University has been combing research on the modern hydrological system with oxygen isotope values from the core sediments to study how access to freshwater changed over time as a result of rising sea-levels. The team has to bring all of their drinking water with them to the site, so they are keenly aware what a limiting factor freshwater access could have been for past peoples. One idea is that there were springs near the site in the past that have been effectively drowned by rising sea level. To try to identify freshwater seeps (that are about two degrees Celsius cooler than the ocean water) the team is using a drone equipped with a thermal camera to identify areas that might represent past sources of freshwater.

The team also uncovered tens of thousands of pieces of pottery and hundreds of pieces of obsidian (volcanic glass used to make tools that can be traced to its original geologic location), which reveal these coastal peoples were involved in extensive trade. Glover says the diversity of these artifacts stands out when compared to that of nearby, inland sites. The research team believes the archaeological data reinforce the idea that these coastal peoples had much broader and more cosmopolitan connections because they were part of long-distance, canoe-based trade networks.

These trade connections are most evident about 1,000 years ago when researchers see a major realignment and expansion in international trade associated with the emergence of Chichen Itza as a powerful religious, political, and economic city.

“Strong evidence of this realignment comes from the obsidian data which reveals greater connections to parts of central Mexico, near modern day Mexico City” Glover said.

Many of these artifacts come from poring over the detritus—or garbage—left behind by this past civilization, Glover says this is often an archeologist’s goldmine. Mixed with the pottery and obsidian, the research team found items like spindle whorls, that would have been used to make cotton thread which could have been traded as bolts of cloth or used for fishing lines or nets.

When asked what is missing, Rissolo said “We would love to find an intact ancient Maya trading canoe! It’s possible that such a vessel may be preserved beneath the muddy bottom of the bays surrounding Vista Alegre. We would learn so much about these legendary watercraft.”

The team also discovered an array of natural materials, including more than 20,000 animal bones, from sharks, rays, turtles and marine gastropods (gastropods include animals like conchs and whelks which have been studied by another project leader, Dr. Derek Smith). The team is working closely with Mexican archeologists at the Autonomous University of Yucatan in Merida, Mexico to analyze the animal remains and burial sites that have been discovered.

Research came to a halt during much of the pandemic, but after months of excavations and discovery of so many artifacts, the team is still working to analyze their findings. Glover said they are also in discussions with local leaders in Mexico to create a community museum to highlight the region’s rich cultural and natural history.

Often, when people think about the ancient Maya, they may picture some sudden, cataclysmic event that upended daily life and led to end of this past, advanced civilization. Glover notes that this could not be further from the truth. Maya peoples are alive and well today in the Yucatan, Belize, and Guatemala. While the ‘collapse’ of Maya kingdoms between 800 and 900 CE often gets blown out of proportion in popular media, that does not mean that were not changes in settlements over time.

“I think it’s a story, not of a sudden or mass exodus, but a shift over time,” Glover explained, “and to understand these shifts we must understand the complex interplay of environmental and cultural factors, which is what our research is revealing.”

The research also highlights the specific lifestyles and adaptive strategies needed to live in a dynamic coastal environment and how this fostered a shared identity amongst coastal Maya communities.

“Our research gives us some idea of the shared challenges that coastal peoples faced – rising sea-levels, diminished freshwater, changing economic and political systems – and they probably leaned on one another, Glover said. “In some ways, I think it might have been easier to hop in your canoe and paddle down the coast to seek help than it was to walk over land.”

“The past, just like the present is not static, and these people were constantly having to make decisions. Sometimes those decisions meant sticking it out, and sometimes they meant re-establishing their lives right down the coast. This new article is a great summation of what we have learned to date. But, you know, there’s always more to be done, and we certainly have plans to continue.” Glover said.

Later this year, the team will start a new project with Dr. Tim Murtha, a colleague at University of Florida, to conduct a light detection and ranging (LIDAR) survey. They will collect detailed elevation data that can reveal the distribution of ancient Maya settlements like house mounds or pyramids. While not focused on the coast, the project will help the team better understand the relationship between inland and coastal communities.

On this project, Glover and Rissolo teamed with Dr. Patricia Beddows (Northwestern University), Dr. Beverly Goodman (University of Haifa), Dr. Derek Smith (University of Washington), and others under the auspices of Mexico’s National Institute of Anthropology and History (INAH).

University of Toronto Engineering researchers have grown a small-scale model of a human left heart ventricle in the lab. The bioartificial tissue construct is made with living heart cells and beats strongly enough to pump fluid inside a bioreactor.

In the human heart, the left ventricle is the one that pumps freshly oxygenated blood into the aorta, and from there into the rest of the body. The new lab-grown model could offer researchers a new way to study a wide range of heart diseases and conditions, as well as to test out potential therapies.

“With our model, we can measure ejection volume — how much fluid gets pushed out each time the ventricle contracts — as well as the pressure of that fluid,” says Sargol Okhovatian. “Both of these were nearly impossible to get with previous models.”

Okhovatian and Mohammad Hossein Mohammadi are co-lead authors on a new paper in Advanced Biology that describes the model they designed. Their multidisciplinary team was led by Professor Milica Radisic, senior author of the paper.

All three researchers are members of the Centre for Research and Applications in Fluidic Technologies (CRAFT). A unique partnership between Canada’s National Research Council and the University of Toronto, CRAFT is home to world-leading experts who design, build and test miniaturized devices to control fluid flow at the micron scale, a field known as microfluidics.

“The unique facilities we have at CRAFT enable us to create sophisticated organ-on-a-chip models like this one,” says Radisic.

“With these models, we can study not only cell function, but tissue function and organ function, all without the need for invasive surgery or animal experimentation. We can also use them to screen large libraries of drug candidate molecules for positive or negative effects.”

Many of the challenges facing tissue engineers relate to geometry: while it’s easy to grow human cells in two dimensions — for example, in a flat petri dish — the results don’t look much like real tissue or organs as they would appear in the human body.

To move into three dimensions, Radisic and her team use tiny scaffolds made from biocompatible polymers. The scaffolds, which are often patterned with grooves or mesh-like structures, are seeded with heart muscle cells and left to grow in a liquid medium.

Over time, the living cells grow together, forming a tissue. The underlying shape or pattern of the scaffold encourages the growing cells to align or stretch in a particular direction. Electrical pulses can even be used to control how fast they beat — a kind of training gym for the heart tissue.

For the bioartificial left ventricle, Okhovatian and Mohammadi created a scaffold shaped like a flat sheet of three mesh-like panels. After seeding the scaffold with cells and allowing them to grow for about a week, the researchers rolled the sheet around a hollow polymer shaft, which they call a mandrel.

The result: a tube composed of three overlapping layers of heart cells that beat in unison, pumping fluid out of the hole at the end. The inner diameter of the tube is 0.5 millimetres and its height is about 1 millimetre, making it the size of the ventricle in a human fetus at about the 19th week of gestation.

“Until now, there have only been a handful of attempts to create a truly 3D model of a ventricle, as opposed to flat sheets of heart tissue,” says Radisic.

“Virtually all of those have been made with a single layer of cells. But a real heart has many layers, and the cells in each layer are oriented at different angles. When the heart beats, these layers not only contract, they also twist, a bit like how you twist a towel to wring water out of it. This enables the heart to pump more blood than it otherwise would.”

The team was able to replicate this twisting arrangement by patterning each of their three panels with grooves at different angles to each other.

In collaboration with Professor Ren-Ke Li’s lab within the University Health Network, they measured the ejection volume and pressure using a conductance catheter, the same tool used to assess these parameters in living patients.

At the moment, the model can only produce a small fraction — less than 5% — of the ejection pressure that a real heart could, but Okhovatian says that this is to be expected given the scale of the model.

“Our model has three layers, but a real heart would have eleven,” she says.

“We can add more layers, but that makes it hard for oxygen to diffuse through, so the cells in the middle layers start to die. Real hearts have vasculature, or blood vessels, to solve this problem, so we need to find a way to replicate that.”

Okhovatian says that in addition to the vasculature issue, future work will focus on increasing the density of cells in order to increase the ejection volume and pressure. She also wants to find a way to shrink or eventually remove the scaffold, which a real heart wouldn’t have.

Though the proof-of-concept model represents significant progress, there is still a long way to go before fully functional artificial organs are possible.

“We have to remember that it took us millions of years to evolve a structure as complex as the human heart,” says Radisic.

“We’re not going to be able reverse engineer the whole thing in just a few years, but with each incremental improvement, these models become more useful to researchers and clinicians around the world.”

“The dream of every tissue engineer is to grow organs that are fully ready to be transplanted into the human body,” Okhovatian.

“We are still many years away from that, but I feel like this bioartificial ventricle is an important stepping-stone.”
