What Can We Learn From the Quantum Field

quantum field

The quantum field offers a deep well of knowledge for physicists and has numerous implications for our understanding of the universe. Here are some key takeaways:

1. The Nature of Particles and Forces: Quantum field theory (QFT) provides a framework to understand the fundamental particles that makeup matter and the forces that govern their interactions. It explains how particles aren’t just tiny billiard balls, but rather excitations in underlying fields. This explains how forces like electromagnetism and the strong nuclear force arise.

2. Unveiling the Subatomic World: QFT allows physicists to make predictions about the behavior of particles at incredibly small scales, where classical physics breaks down. This is crucial for understanding phenomena like nuclear reactions that power stars or the behavior of particles in particle accelerators.

3. Unifying the Forces: One of the holy grails of physics is a “theory of everything” that unifies all the fundamental forces. QFT is a strong contender because it provides a consistent framework to describe different forces using the concept of fields. While a complete theory remains elusive, QFT paves the way for unification attempts.

4. New Particle Discoveries: QFT predicts the existence of new particles based on the properties of the fields. The discovery of the Higgs boson, crucial for understanding mass, is a prime example of how QFT guides physicists in their search for new fundamental building blocks.

5. Beyond the Standard Model: The Standard Model of particle physics, based on QFT, is incredibly successful, but it’s not the whole story. Phenomena like dark matter and dark energy remain unexplained. QFT serves as a foundation for exploring new theories that go beyond the Standard Model to provide a more complete picture.

While the intricacies of QFT can be mind-bending, it offers a powerful lens to understand the universe at its most fundamental level. Its influence extends beyond particle physics, with potential applications in areas like quantum computing and material science. As research continues, the quantum field promises to unveil even more secrets about the universe and our place within it.

How fiber and gut bacteria reverse stress damage

How fiber and gut bacteria reverse stress damage
In the stressful world we inhabit, many of us are keen to protect our bodies from the harmful effects that stress can produce. A new study hints that a high-fiber diet might go some way to achieving this.

 

A new study looks deeper at links between gut bacteria and stress.

The bacteria that live in our gut are as numerous as the cells in our body. As medical research progresses, the influence that these billions of tiny creatures have on our health is becoming ever more apparent.

It comes as no surprise that they might play a role in gastrointestinal issues, but the microbiome’s influence flies much further afield.

Most recently, it has become apparent that there is a significant relationship between gut bacteria and mental health issues, such as depression and anxiety.

Stress, the gut, and the brain

Although the thought of a microorganism in our intestines affecting our mental well-being seems like a leap, the gut and brain are deeply entwined. As an example, most people will know how a nerve-wracking situation can influence the speed of our bowels and, vice versa, how being hungry can cast a shadow over our mood.

A troubled brain can inform the gut, and a troubled gut can inform the brain.

Stress, although it is a mental state, can physically affect our gastrointestinal system and the bacterial residents within it. A recent study found that high levels of stress can affect gut bacteria to a similar degree as a high-fat diet; while other studies have shown that reducing the number of bacteria in the gut can produce stress-induced activity in mice.

So, it seems that the road runs both ways: stress can alter gut bacteria, and gut bacteria can influence stress levels. It is a complicated web.

A recent piece of research, published in The Journal of Physiology, takes a fresh look at how gut bacteria are involved in gut health problems induced by stress. The work was carried out at APC Microbiome Ireland at University College Cork and Teagasc Food Research Centre in Ireland.

The role of SCFAs

The team of scientists was interested in short-chain fatty acids (SCFAs). Gut bacteria produce SCFAs when they digest fiber; the cells of the colon then use SCFAs as their primary source of energy, making them vital for good gut health.

The researchers found that when they introduced SCFAs to the guts of mice, stress and anxiety-based behaviors were significantly reduced.

After demonstrating that SCFAs reduce anxiety, they wanted to understand how these small molecules influenced physical, stress-related gut damage.

Known as a “leaky” gut, high levels of stress over time increase the intestine’s permeability. This means that particles, such as bacteria and undigested food, can move more easily into the bloodstream, which can cause damaging chronic inflammation.

The researchers found that by introducing SCFAs, they reduced the gut leakiness caused by persistent stress.

There is a growing recognition of the role of gut bacteria and the chemicals they make in the regulation of physiology and behavior. The role of short-chain fatty acids in this process is poorly understood up until now.” Lead author, Prof. John F. Cryan

What does it all mean?

Fruits, vegetables, and grains naturally contain high levels of fiber. Although this study was conducted on mice, the inference is that a high-fiber diet might prompt gut bacteria to produce more SCFAs — thereby bolstering our gut’s natural defenses against the damage caused by stress.

Of course, plenty more research will be necessary before that conclusion can be written in stone; as Prof. Cryan says, “It will be crucial that we look at whether short-chain fatty acids can ameliorate symptoms of stress-related disorders in humans.”

Future work will also need to dig deeper to get a better understanding of exactly how SCFAs provide these benefits. Unwrapping the molecular shenanigans behind the scenes is likely to be challenging.

The authors hope that the current findings will, eventually, help in the “development of microbiota-targeted therapies for stress-related disorders.”

However, for now, attempting to minimize stress in one’s life while upping consumption of fruit and veg is likely to be a sensible recommendation, whether it impacts levels of SCFAs or not.

Ten Habits Of Incredibly Happy People

We’re always chasing something—be it a promotion, a new car, or a significant other. This leads to the belief that “When (blank) happens, I’ll finally be happy.”

While these major events do make us happy at first, research shows this happiness doesn’t last. A study from Northwestern University measured the happiness levels of regular people against those who had won large lottery prizes the year prior. The researchers were surprised to discover that the happiness ratings of both groups were practically identical.

The mistaken notion that major life events dictate your happiness and sadness is so prevalent that psychologists have a name for it: impact bias. The reality is, event-based happiness is fleeting.

Happiness is synthetic—you either create it, or you don’t. Happiness that lasts is earned through your habits. Supremely happy people have honed habits that maintain their happiness day in, and day out. Try out their habits, and see what they do for you:

1. They slow down to appreciate life’s little pleasures.

By nature, we fall into routines. In some ways, this is a good thing. It saves precious brainpower and creates comfort. However, sometimes you get so caught up in your routine that you fail to appreciate the little things in life. Happy people know how important it is to savor the taste of their meal, revel in the amazing conversation they just had, or even just step outside to take a deep breath of fresh air.

2. They exercise.

Getting your body moving for as little as 10 minutes releases GABA, a neurotransmitter that makes your brain feel soothed and keeps you in control of your impulses. Happy people schedule regular exercise and follow through on it because they know it pays huge dividends for their mood.

3. They spend money on other people.

Research shows that spending money on other people makes you much happier than spending it on yourself. This is especially true of small things that demonstrate effort, such as going out of your way to buy your friend a book that you know they will like.

4. They surround themselves with the right people.

Happiness spreads through people. Surrounding yourself with happy people builds confidence, stimulates creativity, and it’s flat-out fun. Hanging around negative people has the opposite effect. They want people to join their pity party so that they can feel better about themselves. Think of it this way: If a person were smoking, would you sit there all afternoon inhaling the second-hand smoke? You’d distance yourself, and you should do the same with negative people.

5. They stay positive.

Bad things happen to everyone, including happy people. Instead of complaining about how things could have been or should have been, happy people reflect on everything they’re grateful for. Then they find the best solution available to the problem, tackle it, and move on. Nothing fuels unhappiness quite like pessimism. The problem with a pessimistic attitude, apart from the damage it does to your mood, is that it becomes a self-fulfilling prophecy: if you expect bad things, you’re more likely to experience negative events. Pessimistic thoughts are hard to shake off until you recognize how illogical they are. Force yourself to look at the facts, and you’ll see that things are not nearly as bad as they seem.

6. They get enough sleep.

I’ve beaten this one to death over the years and can’t say enough about the importance of sleep in improving your mood, focus, and self-control. When you sleep, your brain literally recharges, removing toxic proteins that accumulate during the day as byproducts of normal neuronal activity. This ensures that you wake up alert and clear-headed. Your energy, attention, and memory are all reduced when you don’t get enough quality sleep. Sleep deprivation also raises stress hormone levels on its own, even without a stressor present. Happy people make sleep a priority because it makes them feel great and they know how lousy they feel when they’re sleep-deprived.

7. They have deep conversations.

Happy people know that happiness and substance go hand-in-hand. They avoid gossip, small talk, and judging others. Instead, they focus on meaningful interactions. They engage with other people on a deeper level, because they know that doing so feels good, builds an emotional connection, and is an interesting way to learn.

8. They help others.

Taking the time to help people not only makes them happy, but it also makes you happy. Helping other people gives you a surge of oxytocin, serotonin, and dopamine, all of which create good feelings. In a Harvard study, employees who helped others were 10 times more likely to be focused at work and 40% more likely to get a promotion. The same study showed that people who consistently provided social support were the most likely to be happy during times of high stress. As long as you make certain that you aren’t overcommitting yourself, helping others is sure to have a positive influence on your mood.

9. They make an effort to be happy.

No one wakes up feeling happy every day and supremely happy people are no exception. They just work at it harder than everyone else. They know how easy it is to get sucked into a routine where you don’t monitor your emotions or actively try to be happy and positive. Happy people constantly evaluate their moods and make decisions with their happiness in mind.

10. They have a growth mindset.

People’s core attitudes fall into one of two categories: a fixed mindset or a growth mindset. With a fixed mindset, you believe you are who you are and you cannot change. This creates problems when you’re challenged because anything that appears to be more than you can handle is bound to make you feel hopeless and overwhelmed. People with a growth mindset believe that they can improve with effort. This makes them happier because they are better at handling difficulties. They also outperform those with a fixed mindset because they embrace challenges, treating them as opportunities to learn something new.

The Key to Work-Life Balance? Integration of Those 2 Concepts.

Work-Life Balance

Want to change into Lycra tights and take a 5-mile bike ride at lunch? That’s absolutely fine if it helps you produce brilliant work that afternoon.

The realities of maintaining a work-life balance have always been challenging. But, better integrating the two concepts is the solution. Managing the way we work both inside and outside of our traditional working day is not only possible but ultimately beneficial, for most people. And, because of technological advancements and changing attitudes in work-life balance, we’ve actually become wired for integration.

Generally, these are all good things, if you consider the creatively oriented thinkers, makers, advisors, and managers staffing industries these days. On the whole, their reaction to a higher degree of autonomy has been a greater commitment and productivity: Combining work and life in more free and flexible ways has become the path to happier employees and stronger businesses.

Yet, we still have to be cautious, because integration and the means for achieving it is a personal issue — what works for one person won’t necessarily work for another. That’s why, as the CEO of a global organization, I’ve encouraged not only innovation and productivity but also better integration. Here are the steps I recommend:

Introducing integration

Change of any kind can be tough on companies and their employees. Reactions such as lethargy, unwillingness to try something new, and phrases like “we don’t do it that way” are poisonous. This is especially true when you’re trying to build a company culture that embraces integration.

That’s why the work environment must be built on trust and space. The goal here is simple: to ensure that your company is a place where output and results are judged above time served. This type of workspace usually includes:

  • Strong communication: There is no such thing as over-communication if you’re trying to move a business through a period of transformation. The path to encouraging integration should feel collaborative. Nor does it need to include everyone. Start with a small group of standout employees who have a history of affecting change, and make them your advocates. That will allow a more organic cultural change. If you don’t communicate and instead try to do it all yourself, you’ll have no chance.
  • Constant empowerment: As a CEO, I’m empowered to recognize what my company needs, to ensure that everyone is productive and effective. However, enabling that same degree of empowerment in others is a management skill in and of itself, and a cultural asset, especially when you’re trying to achieve a better work-life balance.

It’s amazing how quickly cultures can morph to embrace diverse working practices. We’re not still in school, after all. If you want to change into some Lycra tights and head out for a 5-mile bike ride at lunchtime, go for it.

And if that ride enables you to produce brilliant work in the afternoon, it’s better that you’re lapping Central Park than grumpily chewing a bagel at your desk. By breaking work-life balance norms and building flexible cultures, businesses like Netflix, Zappos and Uniqlo have all thrived through the employee empowerment they’ve offered.

Saving time

I personally have three points of focus to maximize my time that could also benefit employees looking for better integration.

Email: I keep regular office hours, but also spend time at the beginning and end of a working day dropping off and picking up my kids from school. To do that, I check and respond to emails outside of the office at dedicated time slots. One might involve a quiet coffee on my own in the morning when I prioritize emails needing my response, or 30 to 60 minutes at the end of the day.

I also believe in the time-quality dynamic when it comes to responses. I’ll accept a response back of “Yes,” “Sure, I’m on it” or “No way we can make that, sorry.” A three-day time lag that ultimately produces a three-paragraph excuse for the slow reply and an equally lengthy explanation? Incredibly unhelpful.

Office time management: Whatever it takes to avoid meeting fatigue, I’m game: standing meetings. 15-minute meetings. Meetings with no written notes. Walk-in-the-park meetings. I haven’t formally instituted these practices across our entire agency, but I was inspired by Percolate’s 6 Meeting Rules, which were created as that company grew from a startup to a success. Rule number one, for example, is, “Do you really need a meeting?” Asking that question in advance has produced remarkable results.

Travel and remote work: Our business runs across 24 offices and every time zone, which means an integrated schedule for me and other employees who travel frequently. I am always prepared to spend a night on an airplane to get home to have breakfast with my family, or take a 10 p.m. conference call with colleagues in Hong Kong to be around for bath time and stories with my kids. These compromises and so many others, are the mark of an integrated life.

Just “let them get on with it”

By introducing integration, your message to employees becomes: “You’re great at what you do. We know you want to be better. You’re here because you have a lot to add to the business and to your colleagues. Get to it.”

A company invested in improving work-life balance should support its employees and enable them to manage their work and personal lives to the best of their abilities. By adopting integration, companies lay down a challenge that people will accept. Those companies should also be identifying employees who don’t, won’t, or can’t work without that type of empowerment. That’s fine, too.

David Abbott, the British ad man who built one of the very best creative businesses of the last 50 years, said it best: “Hire good people and let them get on with it.”

If you — or your systems, processes, promotion, and reward assessments, and 196-page “employee policy” documents — don’t allow those employees to customize their own path to create a more flexible relationship between their work and personal lives, then you may as well not have “good people” in the first place.

The keys, once again, are trust and integration.

8 Things You Should Stop Doing When You Wake Up in the Morning

don't make your bed

As if getting out of bed in the morning wasn’t hard enough, we always seem to be bombarded with all sorts of distractions whenever we first wake up. And while some of our morning routines are filled with healthy rituals to help jumpstart our days (10-minute meditation, anyone?), many of us also practice AM habits that aren’t so beneficial.

From hitting the snooze button to scrolling through your Instagram feed, here are eight things you should avoid doing after you wake up in the morning.

1. Checking social media

Along with being bad for your mental health, mindlessly scrolling through your social media feeds right after you wake up is a surefire way to lose track of time (and your focus) in the morning.

2. Forgetting about breakfast

Whether you prefer egg whites, cereal, or skipping it all together, your morning meal plan should be whatever you (and your health provider) can feel good about. But you should be intentional about it. Adhering to a strategic breakfast plan in the morning will help you better anticipate your schedule for the rest of the day and ensure you don’t get derailed on your way to work.

3. Anything you could have done the night before

Whether it’s picking out an outfit or packing a lunch, anything you can handle ahead of time will help your mornings go more smoothly. Set yourself up for success by planning your day the night before and free up some extra time in the morning.

4. Hitting snooze

We already knew that hitting the snooze button on your alarm will leave you feeling groggy the rest of the day, but it turns out that fragmented sleep is bad for your health too. So instead of slapping the snooze button to score a few measly extra minutes of sleep in the morning, try going to bed a half hour earlier every night.

5. Waking up at inconsistent times

Not only does creating—and sticking to—a set sleep schedule help ensure you get a solid seven to nine hours of sleep every night, it makes waking up in the morning (sans the snooze button) a whole lot easier.

6. Checking your email

Getting out of bed can be tough as is, so why put yourself through the added stress of checking your emails before you even get to work? Experts say that by checking your emails first thing in the AM, you might be setting a stressful tone for the rest of the day, so try your best to avoid checking your email before you actually step foot in the office (or at least until you get to the train).

7. Drinking coffee right away

Like it or not, research shows that drinking a cup of joe first thing in the morning might be doing you any favors. Along with increasing your tolerance to caffeine, research shows that consuming coffee before 10 a.m. can mess with yourL cortisol levels—leaving you feeling groggier and more stressed than you would have felt if you’d waited.

8. Making your bed immediately

Untidy people rejoice: Making your bed, at least right after you wake up, might not be the best course of action. Per BBC News, a group of scientists discovered that leaving your bed unmade to air for a while will help kill off dust mites that thrive in moist environments.
