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
- 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!
- Short hair is easier to manage than long hair, which means less time spent styling and max time getting on with your day.
- 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!
- 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;
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!

Reverse engineering the heart: University of Toronto Engineering team creates bioartificial left ventricle
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.”
Narwhals show physiological disruption in response to seismic survey ship noise
The reaction of narwhals to the loud noise from seismic air guns used in oil exploration involves a disruption of the normal physiological response to intense exercise as the animals try to escape the noise. The overall effect is a large increase in the energetic cost of diving while a paradoxically reduced heart rate alters the circulation of blood and oxygen.
“They’re swimming as hard as they can to get away, and yet their heart rate is not increasing—we think because of a fear response. This affects how much blood and oxygen can circulate, and that’s going to be problematic,” said Terrie Williams, a professor of ecology and evolutionary biology at UC Santa Cruz who led the new study.
Published July 8 in the Journal of Functional Ecology, the study provides the first look at the impact of seismic noise on the physiological responses of a deep-diving cetacean. According to Williams, the combination of extremely low heart rates, increased heart rate variability, and high-intensity exercise during deep dives presents a significant physiological challenge for narwhals, especially if the disruptions are prolonged as would be likely during extended oil exploration activities.
Narwhals live year-round in high Arctic waters where sea ice has helped isolate them from disturbance by humans for millions of years. But declines in polar sea ice are making the region more accessible to shipping, natural resource exploration, and other human activities.
In a previous study, Williams and her coauthors showed that narwhals released after entanglement in nets set by indigenous hunters showed a similar physiological response, with extremely low heart rates during intense exercise in a series of escape dives. The difference between a capture event and noise, Williams said, is the potential duration of the disturbance.
“When they escape from the nets, their heart rate comes back up to a more normal rate within three or four dives, but with the seismic ship moving through and the sound bouncing around, the escape response occurred over a longer period,” she said.
The researchers recorded not only extremely low heart rates during noise exposure, but also increased variability, with heart rates switching rapidly between extremely low rates associated with fear and fast rates associated with intense exercise. Reduced heart rate, or bradycardia, is a normal part of the mammalian dive response, but during normal dives the heart rate still increases with exercise. In addition, narwhals and other deep-diving marine mammals usually save energy by gliding rather than actively swimming as they descend to depth.
During noise exposure, the narwhals performed 80% less gliding during diving descents, their swimming strokes exceeded 40 strokes per minute, their heart rates dropped below 10 beats per minute, and their breathing at the surface was 1.5 times faster. Overall, this unusual reaction is very costly in terms of energy consumption, Williams said.
“Not only is the reaction costly in terms of the energy needed for diving, the escape time will also take away from time spent foraging for food and other normal behaviors,” she said.
The studies were conducted in Scoresby Sound on the east coast of Greenland, where coauthor Mads Peter Heide-Jørgensen, a research professor at the Greenland Institute of Natural Resources, has been studying the East Greenland narwhal population for more than a decade.
Williams’s group at UC Santa Cruz developed instruments that enable researchers to monitor the exercise physiology of marine mammals during dives. The instruments were attached to narwhals with suction cups and fell off after one to three days, floating to the surface where they could be recovered by the scientists.
Over the past two decades, noise from human activities such as military sonar has been linked to mass strandings of deep-diving cetaceans, mostly beaked whales. These deep-diving species are extremely difficult to study, and it was only through a partnership with indigenous hunters that Williams and Heide-Jørgensen’s teams were able to attach monitoring devices to narwhals.
“Most of the potential impacts on the animals take place underwater, so it’s really difficult to study,” Williams said. “We are fortunate to have this technology to show what’s happening at depth where these animals live in order to understand how their biology may be disrupted.”
In addition to Williams and Heide-Jørgensen, the coauthors of the paper include Susan Blackwell at Greeneridge Sciences, Outi Tervo and Eva Garde at the Greenland Institute of Natural Resources, Mikkel-Holger Sinding at University of Copenhagen, and Beau Richter at UC Santa Cruz. This work was supported by the U.S. Office of Naval Research, Greenland Institute of Natural Resources, the Environmental Agency for Mineral Resource Activities of the Government of Greenland, the Danish Ministry of Environment, and the Carlsberg Foundation.
