Welcome to the next chapter of Science with Style! Every other week we'll highlight research, policies, and news related to toxicology and environmental/public health. You can follow us on twitter at @ToxCityTribune for more articles and updates around this topic. Let us know what other research highlights or science news you'd be interested to see here!
New findings from a human cell culture study show that aerosols from e-cigarettes can cause cell death and oxidative stress but at lower levels than standard cigarettes.
The article from the December issue of Toxicological Sciences looked at extracts from four brands of e-cigarettes to see if the aerosols could increase reactive oxygen species levels. Reactive oxygen species, also known as free radicals, cause cellular stress and are known by-products of cigarette smoke.
The study, done at Tulane University, compared free radical levels between standard cigarettes fumes and e-cigarette aerosols. Researchers found that aerosols from e-cigarettes increased the number of free radicals in cells. However, the level of free radical increase only reached 50% of the increase caused by standard cigarette fumes. E-cigarette aerosols also caused cell death and DNA damage but at lower levels when compared to standard cigarettes.
Free radicals are highly-reactive molecules that can build up in the body during exposure to toxic chemicals. High free radical levels cause oxidative stress and are linked to cardiac disease and cancer. Consuming fruits and vegetables with anti-oxidants, such as Vitamin C, is a way to protect against the damage caused by free radicals.
This study also found that anti-oxidant treatment could prevent free radical increases. Certain brands of e-cigarettes already include anti-oxidants in their aerosol formulation. It's not currently known if including vitamins in aerosol can actually prevent free radical levels from increasing during e-cigarette use.
E-cigarettes work by creating very small particles to deliver nicotine in aerosol form, but the exact components of these aerosols are unknown. E-cigarette use is linked to cardiovascular disease but the overall risks of chronic e-cigarette use are still not well-understood.
The results of the study showing that free radical levels are lower in e-cigarette aerosols when compared to standard cigarettes. These increases were mitigated by anti-oxidant treatment in cells, findings that may seem promising to e-cigarette advocates. But an increase in free radicals, however small, is still cause for concern because of links between free radicals and cancer.
The use of e-cigarettes and tobacco alternatives are currently on the rise. A large number of students under 18 are using e-cigarettes before they switch to standard cigarettes. A survey of high school students found that many believed e-cigarettes to be a safe alternative to cigarettes, showing a lack of understanding about the risks of e-cigarettes among younger users.
This study shows that e-cigarettes may have harmful effects, even if the risk is lower than for standard cigarettes. These findings also show a need for more thorough studies of the clinical risks of long-term e-cigarette usage.
After a time for self-reflection at the end of 2016 and a re-energizing holiday break, many of us have optimistic ideas for what we want to achieve in the next 365 days. It can feel like nothing will stand in the way of us achieving the goals that we set at the start of a new year. Unfortunately, New Year’s resolutions have a tendency to quickly fall to the wayside after those first few weeks of post-Christmas energy start to wear off. That elated, fresh-start feeling we have on January 1st feels all-too-quickly dispersed by the time we arrive at those gloomy and gray days of February, when over half of us will have already given up on our resolution. This can leave us wondering if there’s really any point in making a resolution each and every new year given that so many of us fail to follow through.
Here at Science with Style, we believe that any time of the year is an opportunity for a fresh start, for self-reflection, and for setting goals. Any goal that’s made with your professional or personal growth in mind is never a waste of time, especially if the end result is something of importance for you or your future career. It’s easy to sit on your couch (or, if you’re the more adventurous type, out on the town) watching the lights drop on New Year’s Eve and dream of things you want to achieve but can be difficult when you don’t really know how you’ll get there.
To help you stay on track with achieving your resolutions, not just until January but for the rest of 2017, here are our recommendations for what you can do to truly make this year a great one:
- Be precise. Develop a clear vision of what you want to achieve and make a target. Instead of saying “I want to write a paper” or “I want to have a better work-life balance”, set a specific goal. Maybe it’s writing 200 words a day of your thesis/manuscript, a dedicated amount of time each week for writing, or a set time during the week when you chat with friends over coffee instead of writing emails. Being clear and precise prevents you from making a nebulous goal that is hard to keep. A clear goal also gives you a road map on how to start with a resolution.
Along with a short-term goal (like something you achieve on a daily or weekly basis), set intermediate targets for yourself to help keep track of your progress throughout the year. If your goal is to write and you aim for 200 words a day, you’ll have made it to over 3,000 by the end of the month—that’s over half of a paper already done! Set small targets on a day-by-day basis that you’re not going to feel intimidated by. These specific targets can help you see how much time it will take you to finish intermediate goals, like completing the literature review section of a thesis, and you can also work with your mentor or advisor to keep track of your work progress on a more regular basis.
- Be realistic. As much as I hate to admit it, there are really only so many hours in a day and only so much time outside of lab hours that we can devote to our personal goals. It’s good to stay busy but you also want to avoid overloading yourself to the point that you no longer have any time to relax. Stretching yourself too thin will only lead to you feeling more burned out and more likely to give up on a new year’s resolution that’s taking too much of your free time.
As you’re setting your specific goals, think of the other needs you have during the week apart from lab work. It could be a weekly racquetball game with a colleague or a recurring Saturday brunch with your friends. Don’t double-book yourself against your time that you normally use for recreation or socialization and instead find time in the remaining part of your week. Even if it’s only 10-15 minutes, a set amount of time devoted to a task can quickly add up without interfering with the rest of your like. If you do something for your career for just 10 minutes every day, it adds up to over 60 hours of time that you’ve devoted to a personal goal over the entire year. That’s over a full week’s worth of work!
- Be accountable. Some people are very good at staying self-motivated while others find it difficult to meet goals without an external deadline or other source of accountability. If you have trouble keeping goals on your own, find a friend, colleague, or mentor who’s also making resolutions at work together to hold each other accountable on your milestones. Meet with your accountability buddy on a regular basis and talk about your progress. If you’re not making progress or are struggling with something, you can talk to your buddy about it and avoid waiting until it’s too late to figure out how to change your strategy.
- Be flexible. An item on your to do list that you put there on a Monday can frequently end up still sitting on your list on that Friday afternoon. Sometimes our weeks and days are busier than we anticipate, last-minute things pop up that take more time than we planned, or something comes up that distracts us from other tasks at hand. Not achieving everything you set out to do doesn’t mean you’re doomed to fall behind or eventually fail at your goal, so don’t beat yourself up about it.
Rank your goals ahead of time so you know which ones are more important and deserve nmore of your focus. Then you can let the less important ones fall aside during busier times, such as getting ready for a conference or a big experiment. This can help keep you from over-extending yourself while still enabling you to achieve the most important items in your to do list and also lets you be flexible when busier times arise, as they inevitably do.
- Be optimistic. Maybe it’s the post-holiday crash of going back to work/school after a nice break or the nasty winter weather—whatever the reason, you tend to see a lot of negativity and general grumbling this time of year. Even if you’re a positive person, being surrounded by negativity can work its way into your head, and it make it tempting to leave your goals behind.
As difficult as it is, especially during this post-holiday malaise, try to keep yourself in positive spirits during these weeks of the winter season. Start your year off with simple goals before you jump into the more heavy duty to do’s, like cleaning up your desk or lab bench or catching up with a friend or colleague you haven’t seen in a while. Use these small achievements to give you some initial momentum for the rest of the year as you tackle your larger goals. Take time to find enjoyment outside of work and you resolutions by doing things that keep gloominess at bay: see a film with friends, try a new recipe, or visit an art exhibit. There are lots of ways to stay optimistic and inspired even during the colder and drearier months of the year.
The New Year can always be an opportunity for making a fresh start, and I hope this list will help you in your goals for an excellent 2017. In terms of my own resolutions, my primary goal is to write outside of my comfort zone. I’ve gotten into the habit of the weekly Science with Style posts but am now looking to challenge myself beyond the weekly long-form blog. This means I’ll be trying out my hand at some short freelance pieces, news-oriented writing, and even some fiction. I’ll be scaling down the SwS posts to twice a month to help me keep up with my resolution—but have no fear: there’s lots to see in our archives and I’ll still be posting articles and discussions on twitter on a regular basis.
I hope you all are having a wonderful, inspiring, and also relaxing start to your 2017. We’ll see you again in two weeks’ time—hopefully you’re more than ready for another year of doing science with style!
