Country singer Carly Pearce has made a career out of writing songs that tackle her own breakups and heartbreaks. And the 29-year-old singer relies on a powerful personal mantra to keep herself strong when relationships and other issues start wearing on her.

“The mantra that I feel like has influenced me in a huge way is, 'there is beauty in vulnerability,'” Pearce tells Health. “And I don’t know if I heard that somewhere or it's just my interpretation of so much that’s happened to me in the past few years.”

Pearce explains that one of her first hits, “Every Little Thing,” showed that vulnerability. “I don’t know that you can get more raw, real, or vulnerable than that,” she says. “And I feel like that moment, when I saw what that song did, it made me kind of look into my life and understand that sometimes great things come from being honest.”

The song doesn't just apply to breakups, she adds. She uses this mantra when dealing with trolls on the internet, too. 

“When I’m talking to anybody or just being Carly or playing a show or on social media, I really try to just really speak my truth and not be afraid of vulnerability,” she says. “Because if we're all the same and we all pretended that everything was okay, we wouldn’t have the scars and the grit and the just little ins and outs of things that make us, us.”

Pearce has a couple of other mantras that help inspire her as well. “Everything happens for a reason" is one she calls on to make sense of her journey.

“I struggled in Nashville for 10 years, cleaning Airbnbs, working retail, being a backup singer, not wanting to do that and not understanding why I had to do that,” she recalls.

“Fast forward and those 10 years in Nashville prepared me for the schedule and the life that I was about to have," she says. "And no matter what you’re going through in life, no matter what season you’re in, if it’s a hard one, if it’s a good one, understand that things happen to prepare you for what’s next, and everything does happen for a reason, and one day you’re gonna look back and understand why.”

Another mantra she uses (especially when internet trolls come out) focuses on body positivity and self acceptance. "'Love the skin you're in'—I think that is just an empowering thing for body image.”

"Instead of hiding what some little people have said to me, I’ve decided to just exploit some of the things that I go through with body shaming," she explains. "As women, we need to learn more about loving who we are and loving the skin that we’ve been given and loving our shape."

Pearce says she tries to remind herself of the beauty in being unique, and she wants fans to see this as well.

"Everybody deals with body image and everyone deals with loving themselves, and I think that what’s so interesting is you exude confidence when you feel confident in your own skin," she adds. "It’s not about a size of jeans you wear, it’s not about a number on a scale, it’s not about any of that. It’s about loving who you are and loving the skin that you were given."

Smart intersections could cut autonomous car congestion

In the not-so-distant future, city streets could be flooded with autonomous vehicles. Self-driving cars can move faster and travel closer together, allowing more of them to fit on the road — potentially leading to congestion and gridlock on city streets.

A new study by Cornell researchers developed a first-of-its-kind model to control traffic and intersections in order to increase car capacity on urban streets, reduce congestion and minimize accidents.

“For the future of mobility, so much attention has been paid to autonomous cars,” said Oliver Gao, professor of civil and environmental engineering and senior author of the study, which published in Transportation Research Part B.

“If you have all these autonomous cars on the road, you’ll see that our roads and our intersections could become the limiting factor,” Gao said. “In this paper we look at the interaction between autonomous cars and our infrastructure on the ground so we can unlock the real capacity of autonomous transportation.”

The researchers’ model allows groups of autonomous cars, known as platoons, to pass through one-way intersections without waiting, and the results of a microsimulation showed it increased the capacity of vehicles on city streets up to 138% over a conventional traffic signal system, according to the study. The model assumes only autonomous cars are on the road; Gao’s team is addressing situations with a combination of autonomous and human-driven cars in future research.

Car manufacturers and researchers around the world are developing prototypes of self-driving cars, which are expected to be introduced by 2025. But until now, little research has focused on the infrastructure that will support these driverless cars.

Autonomous vehicles will be able to communicate with each other, offering opportunities for coordination and efficiency. The researchers’ model takes advantage of this capability, as well as smart infrastructure, in order to optimize traffic so cars can pass quickly and safely through intersections.

“Instead of having a fixed green or red light at the intersection, these cycles can be adjusted dynamically,” Gao said. “And this control can be adjusted to allow for platoons of cars to pass.”

Uncertain role of natural gas in the transition to clean energy

A new MIT study examines the opposing roles of natural gas in the battle against climate change — as a bridge toward a lower-emissions future, but also a contributor to greenhouse gas emissions.

Natural gas, which is mostly methane, is viewed as a significant “bridge fuel” to help the world move away from the greenhouse gas emissions of fossil fuels, since burning natural gas for electricity produces about half as much carbon dioxide as burning coal. But methane is itself a potent greenhouse gas, and it currently leaks from production wells, storage tanks, pipelines, and urban distribution pipes for natural gas. Increasing its usage, as a strategy for decarbonizing the electricity supply, will also increase the potential for such “fugitive” methane emissions, although there is great uncertainty about how much to expect. Recent studies have documented the difficulty in even measuring today’s emissions levels.

This uncertainty adds to the difficulty of assessing natural gas’ role as a bridge to a net-zero-carbon energy system, and in knowing when to transition away from it. But strategic choices must be made now about whether to invest in natural gas infrastructure. This inspired MIT researchers to quantify timelines for cleaning up natural gas infrastructure in the United States or accelerating a shift away from it, while recognizing the uncertainty about fugitive methane emissions.

The study shows that in order for natural gas to be a major component of the nation’s effort to meet greenhouse gas reduction targets over the coming decade, present methods of controlling methane leakage would have to improve by anywhere from 30 to 90 percent. Given current difficulties in monitoring methane, achieving those levels of reduction may be a challenge. Methane is a valuable commodity, and therefore companies producing, storing, and distributing it already have some incentive to minimize its losses. However, despite this, even intentional natural gas venting and flaring (emitting carbon dioxide) continues.

The study also finds policies that favor moving directly to carbon-free power sources, such as wind, solar, and nuclear, could meet the emissions targets without requiring such improvements in leakage mitigation, even though natural gas use would still be a significant part of the energy mix.

The researchers compared several different scenarios for curbing methane from the electric generation system in order to meet a target for 2030 of a 32 percent cut in carbon dioxide-equivalent emissions relative to 2005 levels, which is consistent with past U.S. commitments to mitigate climate change. The findings appear today in the journal Environmental Research Letters, in a paper by MIT postdoc Magdalena Klemun and Associate Professor Jessika Trancik.

Methane is a much stronger greenhouse gas than carbon dioxide, although how much more depends on the timeframe you choose to look at. Although methane traps heat much more, it doesn’t last as long once it’s in the atmosphere — for decades, not centuries. When averaged over a 100-year timeline, which is the comparison most widely used, methane is approximately 25 times more powerful than carbon dioxide. But averaged over a 20-year period, it is 86 times stronger.

The actual leakage rates associated with the use of methane are widely distributed, highly variable, and very hard to pin down. Using figures from a variety of sources, the researchers found the overall range to be somewhere between 1.5 percent and 4.9 percent of the amount of gas produced and distributed. Some of this happens right at the wells, some occurs during processing and from storage tanks, and some is from the distribution system. Thus, a variety of different kinds of monitoring systems and mitigation measures may be needed to address the different conditions.

“Fugitive emissions can be escaping all the way from where natural gas is being extracted and produced, all the way along to the end user,” Trancik says. “It’s difficult and expensive to monitor it along the way.”

That in itself poses a challenge. “An important thing to keep in mind when thinking about greenhouse gases,” she says, “is that the difficulty in tracking and measuring methane is itself a risk.” If researchers are unsure how much there is and where it is, it’s hard for policymakers to formulate effective strategies to mitigate it. This study’s approach is to embrace the uncertainty instead of being hamstrung by it, Trancik says: The uncertainty itself should inform current strategies, the authors say, by motivating investments in leak detection to reduce uncertainty, or a faster transition away from natural gas.

“Emissions rates for the same type of equipment, in the same year, can vary significantly,” adds Klemun. “It can vary depending on which time of day you measure it, or which time of year. There are a lot of factors.”

Much attention has focused on so-called “super-emitters,” but even these can be difficult to track down. “In many data sets, a small fraction of point sources contributes disproportionately to overall emissions,” Klemun says. “If it were easy to predict where these occur, and if we better understood why, detection and repair programs could become more targeted.” But achieving this will require additional data with high spatial resolution, covering wide areas and many segments of the supply chain, she says.

The researchers looked at the whole range of uncertainties, from how much methane is escaping to how to characterize its climate impacts, under a variety of different scenarios. One approach places strong emphasis on replacing coal-fired plants with natural gas, for example; others increase investment in zero-carbon sources while still maintaining a role for natural gas.

In the first approach, methane emissions from the U.S. power sector would need to be reduced by 30 to 90 percent from today’s levels by 2030, along with a 20 percent reduction in carbon dioxide. Alternatively, that target could be met through even greater carbon dioxide reductions, such as through faster expansion of low-carbon electricity, without requiring any reductions in natural gas leakage rates. The higher end of the published ranges reflects greater emphasis on methane’s short-term warming contribution.

One question raised by the study is how much to invest in developing technologies and infrastructure for safely expanding natural gas use, given the difficulties in measuring and mitigating methane emissions, and given that virtually all scenarios for meeting greenhouse gas reduction targets call for ultimately phasing out natural gas that doesn’t include carbon capture and storage by mid-century. “A certain amount of investment probably makes sense to improve and make use of current infrastructure, but if you’re interested in really deep reduction targets, our results make it harder to make a case for that expansion right now,” Trancik says.

The detailed analysis in this study should provide guidance for local and regional regulators as well as policymakers all the way to federal agencies, they say. The insights also apply to other economies relying on natural gas. The best choices and exact timelines are likely to vary depending on local circumstances, but the study frames the issue by examining a variety of possibilities that include the extremes in both directions — that is, toward investing mostly in improving the natural gas infrastructure while expanding its use, or accelerating a move away from it.

The research was supported by the MIT Environmental Solutions Initiative. The researchers also received support from MIT’s Policy Lab at the Center for International Studies.

Scientists show how tiny, mutated neuron antennae impair brain connectivity

Axons are the long thread-like extensions of neurons that send electrical signals to other brain cells. Thanks to axonal connectivity, our brains and bodies can do all necessary tasks. Even before we’re born, we need axons to grow in tracts throughout gray matter and connect properly as our brains develop. UNC School of Medicine researchers have now found a key reason why connectivity goes awry and leads to rare but debilitating neurodevelopmental conditions.

Published in the journal Developmental Cell, researchers led by Eva Anton, PhD, professor of cell biology and physiology at UNC-Chapel Hill, show how two gene mutations alter the function of neuronal cilia — antennae-like protuberances found on many cell types. The resulting dysfunctional cilia affect axonal connectivity and leads to rare Joubert syndrome-related disorders (JSRD).

“Our experiments demonstrate that ciliary signaling facilitates appropriate patterns of axon tract development and connectivity,” said Anton, who is a member of the UNC Neuroscience Center. “Disrupting ciliary signaling can lead to axonal tract malformations in JSRD.”

Although cilia are found on most cell types, their significance in brain development, has been largely underappreciated, until recently.

Scientists now know that cilia sense the environment around them, and dysfunctional cilia mess up axonal growth and connectivity during fetal development. Babies born with dysfunctional cilia and associated irregular axonal growth and connectivity can develop JSRD. Molar tooth sign, a characteristic defect of axonal projections detectable in brain MRI images, is often used to diagnose JSRD. People with the condition experience developmental delays, intellectual disabilities, abnormal respiratory rhythms, trouble controlling their body movements, and other serious health issues. But how this happens has not been clear.

Using neuron-specific mouse genetic models of two genes called Arl13b and Inpp5 and related human mutations from JSRD patients, as well as chemo-genetic and opto-genetic manipulation of primary cilia signaling, Anton and colleagues investigated how cilia become dysfunctional and affect axonal connectivity during brain development.

In mice, they found that deletion of Arl13b or Inpp5e impairs the ability of the primary cilium to function as a signaling hub, thus allowing them to examine how cilia-driven signaling regulates axon growth and connectivity in normal and JSRD brains. Anton and colleagues went on to delineate ciliary-driven changes in cell signaling, particularly the ones mediated through major signaling proteins PI3K AKT, and AC3 effectively modulate axonal behavior.

Before this research, the significance of primary cilia in the emergence of brain connectivity were undefined. Nor did the research community understand exactly how cilia dysregulation led to axonal tract defects in Joubert syndrome-related disorders.

“By shedding light on the significance of primary cilia in the emergence of brain connectivity, this research helps us understand how cilia dysregulation led to axonal tract defects in Joubert syndrome-related disorders,” Anton said. “Our studies indicate precise manipulation of ciliary signaling in the future may be tested and utilized to alleviate neuronal connectivity defects in ciliopathies, such as JSRD.”

This research was funded by the National Institutes of Health and the Natural Sciences and Engineering Research Council of Canada.

Health24.com | The best way to shave your bikini line without getting ingrown hair

If you’re one of the 77 percent of women who shave their bikini line, then you know the full pain of a shave gone wrong resulting in bumps, ingrown hair and angry red skin. Sometimes it seems like they’re just part of the package when it comes to shaving ~down there~. (TBH, it makes it almost not worth it.)

What causes ingrown hair?

Ingrown hair occurs when your pubic hair curls back into the skin instead of growing to the surface of the skin after shaving, waxing or plucking the hair.

If you notice small round bumps or bumps filled with puss, you could have an ingrown hair. In certain instances, the skin around the ingrown hair may become hyperpigmented, making that specific area look darker than usual. And . . . you will feel it!

Most of us know how uncomfortable, painful and itchy they can be.

So is there even a good way to shave — or should you just splurge on a wax? Turns out, you can totally shave your pubic hair without getting all the bumps and irritation — you just have to be mindful of these seven expert tips.

1. Invest in a good bikini razor

Picking the right razor is the first step to ensuring your bikini line is smooth and bump-free. “If there are more blades, it dispenses more pressure, allowing each blade to cut with less force but more effect,” says Dr Dendy Engelman, of Manhattan Dermatology and Cosmetic Surgery in New York City. In other words, you’ll get a better, closer shave without risking a cut or irritation.

“Choosing a firm, sturdy razor with soothing strips will make a huge difference,” adds Eileen Bischoff, esthetician and hair-removal specialist at Eve Salon in New York City. While throwaways are great for use while travelling and can get the job done, they’re labelled “disposable” for a reason. “They’re not meant to be used for a month,” she says.

2. Prep to prevent ingrown hair on your bikini line

Before shaving your bikini area, spend about 10 minutes in warm water first. This will help soften the outer layer of your skin, making it easier to remove hair (and lessen your chances of getting razor burn), says Fumi Ozaki, an esthetician and electrologist in Redondo Beach, California. “After the 10 minutes is up, pat the skin dry to remove any excess water,” she says.

Once your bikini line has been cleaned and dried, Engelman suggests lightly exfoliating with a wet washcloth or a scrub to remove dead skin cells, allowing the blade to get closer to the skin. “It teases out any stubborn ingrown hairs prior to shaving,” she says.

3. Don’t skip shaving cream

You might think this shaving accessory is just a feel- and smell-good component to the process, but it’s way more than that. “When you shave, you’re shaving your skin, too,” says Bischoff. “If you don’t use enough shaving cream to create enough slip, you’ll lightly abrade your skin, leaving it irritated.” Ouch.

And similarly to that quality bikini shaver you’re supposed to buy, don’t just reach for a random, cheap shaving cream. “Use a good-quality shaving gel with a shortlist of moisturizing ingredients, like shea butter, olive oil, and coconut oil — these types of bases will give a proper buffer for your razor,” says Engelman.

Apply a very thin layer only to the area that needs to be shaved so you can see the skin and hair shaft underneath. “This is much safer, so there’s no need to move the blade back and forth on the skin,” says Ozaki.

4. Pay attention to your shaving direction

People have a lot of opinions about whether you should shave up or down on your bikini line, and the direction you shave does matter. “How you shave can be really, really important, especially for people who are prone to bumps,” says Bischoff. Going in a ton of different directions with your razor makes cuts and subsequent ingrown hairs more likely.

Shave in one direction — with the hair growth. Going against the grain of your hair makes irritation much more likely.

While gliding your razor gently along the bikini line, keep the blade downward without adding too much pressure. “One pass should be fine, especially if you’re using a razor that has many blades,” says Ozaki. “The more blades used, the fewer times you should feel the need to re-shave over this sensitive area.”

5. Calm your skin after shaving the bikini area

Wash off as soon as you put your razor down, and hold a cold compress to the area for 10 minutes to prevent irritation, says Ozaki. Apply an anti-redness serum (preferably fragrance-free) to further reduce your chances of experiencing razor burn. “I recommend tea tree oil, both a natural anti-inflammatory and antiseptic, which can help calm razor burn,” says Engelman. “If you’ve really caused some irritation, more intense creams, like topical steroids, can be prescribed to reduce redness, swelling, and pain.”

6. Moisturise, moisturise, moisturise

It’s important to always hydrate and moisturise after shaving. “Apply an unscented, alcohol-free moisturiser to both sides of the bikini line to lock in the moisture and avoid over-drying, which leads to further irritation,” says Engelman. Bischoff suggests looking for products containing soothing aloe vera, as well as jojoba oil and vitamin E for hydration.

7. Clean your bikini razor

After every shave, make sure to sanitize your blades with rubbing alcohol and warm or hot water. If your razor looks rusty and you’ve been using it for a while, toss it out. “Replace old blades — ones you’ve used for more than five to seven shaves,” says Engelman.

You can also cut your losses (and avoid those red bumps) by storing blades in a clean, dry place so they don’t pick up bacteria sitting around in the shower.

Treating ingrown hair

If you’re currently dealing with ingrown hair, it’s no cause for major concern. They tend to clear up without any treatment. But if you start to feel like the hair is not growing back and the irritation is not going away – there are a few strategies you can apply to make it better:

  • Don’t remove hair in that area until your ingrown has healed as this could cause scarring and could further irritate ingrown hair increasing your discomfort
  • Slowly pull out the hair with a sterile tweezer once it starts to show above the skin, but don’t pull it out completely. Just keep pulling at it gradually overtime until the area is healed
  • Get a warm compress, this could even be a warm and wet cloth, and rub the area with the ingrown hair softly in a circular motion every time you take a shower.
  • If your ingrown hair seems to be getting worse overtime and the redness and inflammation aren’t getting better, make an appointment with your doctor. Your doctor will most likely prescribe a topical agent to help with the redness and inflammation

Health24.com | Ummm, does sunscreen really expire?

If you can’t remember the last time your bare skin saw the light of day, think twice before applying the first bottle of SPF you find stashed in your bathroom and ask yourself the important question: Does sunscreen expire? Similar to how mascara dries out and gets clumpy, sunscreen also deteriorates over time.

“The ingredients in SPF can break down, losing their effectiveness to filter or block ultraviolet light,” says dermatologist Dr Allison Arthur, a board-certified dermatologist in Orlando, Florida.

Not only can using an old, expired formula be ineffective, but it also can result in a nasty sunburn. Here’s everything else you need to know about how sunscreen expires so you can stay safe in the sun.

What’s the typical shelf life of SPF?

Just like a carton of milk, skincare products have expiration dates. Before applying, double-check what the packaging says to ensure it’s still fresh. But beware: Some bottles may not have one listed.

“If you buy a sunscreen that lacks an expiration date, it’s helpful to write the purchase date on the product so you know how long you’ve had it,” advises Dr Arthur. Forgot to label it? A general rule of thumb is that if it’s over a year old, it’s time to replace it.

The year-rule should be applied to both chemical and physical sunscreens. According to Dr Henry Lim, a dermatologist in Detroit, Michigan, chemical formulations (ones with ingredients such as oxybenzone, avobenzone, and homosalate) will degrade over time due to oxidation, while physical protectants (such as zinc oxide or titanium dioxide) will begin to clump together, rendering them ineffective.

Another thing that could speed up your bottle’s retirement party is heat exposure. “Extreme temperatures may lead to more rapid degradation of sunscreen, especially for chemical filters,” says Dr Arthur, so definitely don’t apply an older bottle that’s been stored in the trunk of a hot car or in a place that doesn’t have AC.

What are the warning signs your sunscreen has expired?

Even if your sunscreen is technically not expired, there are a few tell-tale signs that it’s gone bad prematurely. The first thing to watch out for is any changes in texture. Its consistency should never look or feel different upon application. “If the product becomes watery, grainy, or changes colour, throw it away!” says Dr Arthur.

Another reason to send your SPF on a dumpster dive is if it has a funky smell.

Make sure you’re fully protected.

While a quality sunscreen is the best way to stay safe in the sun — and if you’re applying it daily, there’s really no excuse to have an expired bottle on your hands — there are other things you can do to shield yourself. This is especially true if you’re going to play sunburn roulette with an iffy bottle of SPF that may or may not be expired.

First, try to avoid the peak hours of sunshine, a.k.a. anytime from 10 a.m. to 4 p.m. UV exposure is greater during that time frame compared to earlier in the morning or later in the afternoon.

Remember that shade is your friend too, so plop down under a leafy tree, umbrella, or cabana whenever possible. “Cover up with clothing, wide-brimmed hats, and sunglasses,” adds Dr Arthur. “I am a huge fan of sun protective clothes that use fabrics specifically designed to block UV rays.”

Health24.com | What is a mental reset and how could it improve your health?

Making the decision to live healthier often involves important steps such as losing weight and exercising more. These are significant goals and everyday lifestyle habits that you should commit to. But there’s another type of “makeover” that can benefit you in equally important ways.

That’s changing your general outlook on life by boosting positivity. This mental tweak will put you in a better frame of mind to meet your physical goals. Here’s how to get started.

Look for ways to find more meaning in your life. You might not be able to change your job, but you might be able to take on work challenges that give you a stronger sense of purpose.

If personal and professional commitments have you running in a million directions with none of them emotionally rewarding, reassess your obligations and pare back where you can. Prioritise the tasks that give you a stronger sense of accomplishment.

Next, identify what’s standing in the way of reaching your goals. It might not be complicated. Maybe you want to eat better and exercise more, but you don’t make the time to cook whole foods or go to the gym.

Again, re-prioritise and take action to accomplish what’s important to you. Don’t use roadblocks as excuses to stay stuck.

And because people love instant gratification, give yourself a boost by picking a change you can achieve right away, suggest the experts at Berkeley Wellness.

Ideas include meditating for a few minutes each day, clocking your steps on your smartphone or standing up for two minutes every hour at work.

These are baby steps you can build on to ease stress, get more active and improve your health.
