Study: Paper straws contain toxic ‘forever chemicals’—could be worse than plastic

August 28, 2023

It could be the straw that broke the eco-worrier’s back. Paper straws might not be the “eco-friendly” drinking tube they’ve been promoted to be: Belgian researchers found that these so-called “green” utensils are toxic and therefore potentially worse for the environment than their much-vilified plastic counterparts, according to a new study published in the journal, Food Additives & Contaminants.

“Straws made from plant-based materials, such as paper and bamboo, are often advertised as being more sustainable and eco-friendly than those made from plastic,” Thimo Groffen, Ph.D., study author and an environmental scientist at the University of Antwerp, said in a statement. “However, the presence of PFAS [poly- and perfluoroalkyl-based substances known as “forever chemicals” because they last for a long time before breaking down] in these straws means that’s not necessarily true.”

According to a report by the New York Post, the new research comes following multiple initiatives adopted by numerous U.S. cities, including New York, and by restaurant chains; to ban disposable plastic suckers comprised of polypropylene and polystyrene, which take hundreds of years to decompose and are linked to health problems from liver problems to birth defects.

“Their time has come and gone. I believe we should get rid of plastic straws,” former New York City Mayor Bill de Blasio said in 2018 after the City Council introduced a proposal to prohibit restaurants and bars from distributing plastic sippers.

Meanwhile, countries such as Belgium and the United Kingdom already have ditched these implements in favor of the supposed eco-conscious plant-based alternatives.

However, according to the new research paper, this is a total “strawman argument” — as these alleged environment-saving slushie siphons are potentially packed with more PFAS than the “evil” plastic version.

To deduce this a-straw-calyptic theory, researchers analyzed the PFA concentrations of 39 brands of drinking straws, which comprising five materials: paper, bamboo, glass, stainless steel, and plastic.

They found that paper straws were the most PFA-filled—with a whopping 90% of paper straws containing the chemicals.

Meanwhile, bamboo straws—another highly touted green alternative—clocked in second with 80%,;followed by 75% of plastic straws, 40% of glass straws, and none of steel straws.

By far the most prevalent PFA was perfluorooctanoic acid, which has been been banned globally since 2020. However, this substance is still manufactured in some countries and could be present in products bought by U.S. consumers.

Also present were trifluoroacetic acid and trifluoromethanesulfonic acid; PFAS which easily dissolve in water meaning they could potentially leach out of straws into beverages.

“The presence of PFAS in paper and bamboo straws shows they are not necessarily biodegradable,” warned Groffen.

Not to mention that some of these so-called “100% recyclable” straws are actually anything but.

It’s unclear how these substances — which have been used since the 1940s to repel water and grease in everything from cookware to carpets—ended up in the straws, although the presence of them in every brand suggests they were added on purpose as a liquid repellant.

Other potential PFA sources could be the soil the plant-based materials were grown in as well as the water used in their manufacturing, per Phys.org.

Fortunately, low concentrations of PFAS, such as the amounts ingested from using straws, are unlikely to pose serious health risks.

However, animal studies suggest that an accumulation of these chemicals over time could cause a range of appalling side effects, including liver damage, a weakened immune system, underweight babies, and even infant death.

Unfortunately, the long-term effects on humans are not yet known as the animal tests were conducted with higher levels of PFAs.

In light of the findings, Goffen deduced that plant-based straws are perhaps an environmental “paper tiger” and that there is perhaps only one true eco-friendly alternative to plastic.

“We did not detect any PFAS in stainless-steel straws, so I would advise consumers to use this type ofstraws—or just avoid using straws at all,” the researcher advised.

‘Good Vibrations’ by The Beach Boys makes people happier than any other song

May 25, 2023

“Good Vibrations” by The Beach Boys tops the charts as the song that makes people happiest, according to a university professor’s scientific formula. The 1966 hit single checks all the boxes for Michael Bonshor, Ph.D., who specializes in Music Psychology at the University of Sheffield in Britain, reports Study Finds.

To create a happy song, Dr. Bonshor believes in the combination of a major key, 7th chords, 137 BPM, a strong beat, four beats in every bar, and a verse-chorus-verse-chorus structure. The ditty also should have a short intro, repeated riffs, high volume, bright tone, and a mix of predictability and surprise.

The top ten list of happy songs, according to Bonshor’s formula includes the following:

  1. “Good Vibrations” by The Beach Boys
  2. “I Got You” (I Feel Good) by James Brown
  3. “House of Fun” by Madness
  4. “Get the Party Started” by P!nk
  5. “Uptown Girl” by Billy Joel
  6. “Sun Is Shining” by Bob Marley
  7. “I Get Around” by The Beach Boys
  8. “YMCA” by Village People
  9. “Waterloo” by ABBA
  10. “September” by Earth, Wind & Fire

“Previous studies have found that songs are perceived to be happy if they are in a major key, with a sweet spot of approximately 137 beats per minute,” Dr. Bonshor says in a statement. “We like ‘7th chords’ as they add interest; regular chords use three notes, whereas ‘7th chords’ add an extra note which provides a sense of musical ‘tension’ and ‘relief.’”

“Alongside this, cheery songs usually have a strong 1-2-1-2 beat to them, so that you can dance along—and a short introduction means the song kicks off with a bang straight away, and there’s not a long build up,” Dr. Bonshor notes.

“We like high volume when it comes to how our happy songs are made, with notes played in a bright and bouncy way by instruments such as trumpets or electric guitars instead of mellower instruments. Finally, a repetitive rhythm or guitar riff that people can latch onto and becomes memorable is the cherry on the cake.”

But it’s not just Dr. Bonshor who believes in the ability of some music to lift our spirits. In a recent poll conducted by OnePoll, 46% of adults said singing along to their favorite tracks is a great way to boost their mood. Of those who have specific tunes they turn to in order to cheer up, on average, they have eight numbers on rotation which do the trick.

Nearly six in ten (58%) say these songs have an upbeat feel to them, and the same percentage say they remind them of good memories which put a smile on their face. Meanwhile, 38% say most of their happy tracks were released throughout their teenage years.

The poll also finds that it takes an average of just 14 seconds for these songs to start working their magic. Pop, rock, and dance rank as the three happiest genres of music, while 71% feel music is one of the most powerful influences for changing or reinforcing their mood. Half believe the power of music is actually underestimated, and 38% recognize it can deliver amazing highs and lows.

When reflecting on why music is important to them, 48% put it down to the powerful memories it can evoke and 29% like the fact that they can share it with others. Another 36% have even put on uplifting music around loved ones when they are feeling down to try and lift their spirits.

While half of those who tune in regularly do so within the comforts of their home, 25% consume the most while they are driving.

Singled out: Why unmarried people are stigmatized in our society

September 13, 2018

Are people who remain single likely to be unappealing loners, who are arrogant, antagonistic, or inflexible?  At one time or another, every person who is unattached has felt the stigma or heard the whispers.

Alternatively, those with close relationships or life partners are apt to say that stereotyping of—and discrimination against —singles in our society does not even exist. A different version of the objection concedes that there are ways in which single people are viewed and treated more negatively than married people, but insists that those instances are so inconsequential that they should simply be ignored.

After all, there are other “isms” that are far more serious than “singlism”—the label given to this form of bigotry by social psychologist, Bella DePaulo, Ph.D., who is the author of  the book Singled Out (published by St. Martin’s Press).

She points out, “In many important ways, singles are simply not in the same category as the most brutally stigmatized groups. So far as I know, no persons have ever been dragged to their death at the back of a pick-up truck simply because they were single. There are no “marrieds only” drinkingfountains and there never were. The pity that singles put up with is just not in the same league as the outright hatred conveyed to blacks by shameless racists or the unbridled disgust heaped upon gay men or lesbians by homophobes.”

And singles are by no means a minority: More than 40% of the nation’s adults—over 87 million people—are divorced, widowed, or have always been single.  There are more households of single people living alone than of married parents and their children

And yet, singlism can be quite serious, Dr. De Paulo says in the an article posted on September 9 on the site of Psychology Today.. It can be dangerous, and even deadly.

In part because of laws, policies, and practices that favor married people and couples over single people, the costs of living single can be staggering, she points out. For example, married people, with all their opportunities to draw from their spouse’s benefits, can get far more out of Social Security than single people do. Housing costs, healthcare costs, and taxes are higher for single people. According to one estimate, just those four categories alone can cost single women, over the course of their working lives, over a $1 million more than what married women pay.

In many other ways, too, the price of single life is high. Married men, for example, get paid more than single men. In a study of identical twins, the married twin got paid an average of 26% more. That will cost the single man with a $50,000 salary more than $500,000  over the course of his working life.

In everyday life, single people are penalized financially at every turn. They often pay more per person than married people do for products and services such as car insurance, home insurance, memberships, transportation, travel packages, and even wills.

But even when single people have great health insurance, and access to the finest doctors, they still do not always get the finest care. A single woman told Dr. DePaulo, “When I was 25, I was suffering from severe menstrual problems … to the point where I asked for a hysterectomy. I was refused because I was single and ‘might want to have kids someday.’ So I suffered … for 20 more years.”

Do men respect single women’s bodies and their dignity less than those of married women? In the workplace, the author claims, both single and married women experience sexual harassment—but single women experience it more. In a 2017 Suffolk University survey, 42% of women who had always been single said that a co-worker had made unwanted sexual advances, compared to 30% of married women.

In some businesses, single people are expected to stay later, or cover weekends, holidays, vacation times, or travel assignments that no one else wants, on the assumption that they don’t have anyone and they don’t have a life. When it comes to relocating employees or laying them off, employers sometimes look first to single people—not recognizing that many have roots where they are and do not have a spouse’s income to fall back on if they lose theirs.

“Elsewhere, I … have documented singlism in religionbusiness, advertisingresearch and teachingtherapy, the military, and popular culture,” DePaulo says, adding, “Single parents and their childrenare also a great big target of singlism that is sometimes mean-spirited as well as ill-informed.”

If you still think that singlism just doesn’t matter, and no one should take it seriously, let’s imagine that the tables were turned. Let’s say that all the ways in which single people are stereotyped, stigmatized, marginalized, and discriminated against happened to married people instead. Do you think married people would just shrug it off?

On the first page of her book, Dr. DePaulo imagines a world in which married people get the singles treatment:

  • When you tell people you are married, they tilt their heads and say things like “Aaaawww” or “Don’t worry honey, your turn to divorce will come.”
  • Every time you get married, you feel obligated to give expensive presents to single people.
  • When you travel with your spouse, you each have to pay more than when you travel alone.
  • At work, the single people just assume that you can cover the holidays and all the other inconvenient assignments; they figure that as a married person, you don’t have anything better to do.
  • Single employees can add another adult to their health care plan; you can’t.
  • When your single co-workers die, they can leave their Social Security benefits to the person who is most important to them; you are not allowed to leave yours to anyone—they just go back into the system.
  • Candidates for public office boast about how much they value single people. Some even propose spending more than a billion dollars in federal funding to convince people to stay single, or to get divorced if they already made the mistake of marrying.

If that world existed, it would not last long.

All serious forms of prejudice and discrimination go through a similar process of going unrecognized, then getting dismissed and belittled once people start pointing them out, and in the best cases, eventually getting taken seriously, she points out in her article in Psychology Today.

Dr, DePaulo concludes, “One of the problems is that these matters are not just about the facts and all the ways that racism and sexism and singlism and all the other ‘isms’can be documented with data. They are also about emotions and ideologies and people’s beliefs about the place they think they deserve in the world. I think there will be progress in getting singlism taken seriously, but it may be slow and unsteady, with setbacks as well as advances.”
