Ocean plastic waste probably comes from merchant ships

WASHINGTON — Most of the plastic bottles washing up on the rocky shores of Inaccessible Island, aptly named for its sheer cliffs rising from the middle of the South Atlantic, probably come from Chinese merchant ships, a study published on Monday said. 

The study offers fresh evidence that the vast garbage patches floating in the middle of oceans, which have sparked much consumer hand-wringing in recent years, are less the product of people dumping single-use plastics in waterways or on land, than they are the result of merchant marine vessels tossing their waste overboard by the ton. 

The authors of the study published in the Proceedings of the National Academy of Sciences, or PNAS, collected thousands of pieces of waste during visits to the tiny island in 1984, 2009 and again in 2018. 

The island is located roughly midway between Argentina and South Africa in the South Atlantic gyre, a vast whirlpool of currents that has created what has come to be known as an oceanic garbage patch.

While initial inspections of the trash washing up on the island showed labels indicating it had come from South America, some 3,000 kilometres to the west, by 2018 three-quarters of the garbage appeared to originate from Asia, mostly China.

Many of the plastic bottles had been crushed with their tops screwed on tight, as is customary on board ships to save space, said report author Peter Ryan, director of the FitzPatrick Institute of African Ornithology at the University of Cape Town in South Africa.

Around 90 per cent of the bottles found had been produced in the previous two years, ruling out the possibility that they had been carried by ocean currents over the vast distance from Asia, which would normally take three to five years.

Since the number of Asian fishing vessels has remained stable since the 1990s, while the number of Asian — and in particular, Chinese — cargo vessels has vastly increased in the Atlantic, the researchers concluded that the bottles must come from merchant vessels, which toss them overboard rather than dumping them as trash at ports.

“It’s inescapable that it’s from ships, and it’s not coming from land,” Ryan told AFP. 

“A certain sector of the merchant fleet seems to be doing that, and it seems to be largely an Asian one,” he said. 

 

Fishing nets

 

There are two distinct types of marine pollution.

On the one hand, there are the beaches around urban centres: the plastics that are found there come from coastal areas, and include bottles, bags and packaging. But these things sink easily and are less likely to be carried far by currents. 

Farther out in the oceans, the garbage patches contain fragments of objects of unclear origin, as well as items used by cargo ships and fishing fleets: not just the bottles emptied by the ships’ crews, but also nets, ropes, buoys, crates, barrels and floats.

“It’s an underappreciated cause of pollution,” said Ryan.

Half of the great Pacific garbage patch is made up of fishing nets, by weight, according to a report published last year in Scientific Reports.

Oceanographer Laurent Lebreton, one of the authors of the latter report, said that the oft-quoted figure of 80 per cent of plastic pollution coming from the land does not apply to the high seas. 

He recalled having found huge clusters of nets created by fishing vessels in the North Pacific, known as “fish aggregating devices” to attract fish.

“Often they don’t retrieve them and they are lost. We have found several tonnes of them,” said Lebreton, of the organisation The Ocean Cleanup.

“Everyone talks about saving the oceans by stopping using plastic bags, straws and single use packaging. That’s important, but when we head out on the ocean, that’s not necessarily what we find,” he told AFP.

How to address your roommate’s annoying habits without making things awkward

Roommates suck. Sorry not sorry.

There’s nothing more irritating than coming home after a long day to find an extra body in your dorm or apartment, breathing your air and taking up physical space. Aside from just existing, your roommate probably has a habit (or 15) that you’re not particularly fond of. We’re talking leaving dishes in the sink, playing music too loudly and eating your food.

Learning to live with someone — and how to deal with the habits they bring with them — can be emotionally, physically and spiritually challenging, says Dr Angela Corbo, chair of Widener University’s Communications Studies department.

Sure, living with someone is an experience, a right of passage, even. And who knows, you might end up liking your roomie enough to have a lifelong friendship, but that doesn’t mean you have to quietly suffer through their bad behaviour.

Here are some tips on how to deal with your roommate’s annoying habits without making things awkward at home.

 

Assess the situation

 

Is it really that serious? If you’re living in close quarters with someone, he or she is bound to get on your nerves at some point. So first figure out how important this point of contention between you and your roomie is.

“There are certainly plenty of big issues, especially those that impact your safety or sanity or ability to get a good night’s sleep, but many fall into the category of preferences or simply being different,” says Chris Grace, professor of psychology and director of Biola University’s Centre for Marriage and Relationships.

Corbo adds you should ask yourself a few questions before engaging in a conversation to discern if your problem is based on preference or necessity. For example “if a roommate neglects to make the bed in the morning, for example, ask yourself if that is something that will prevent you from having a productive day?”

 

Communicate effectively

 

Communication doesn’t just mean saying words to your roommate and hoping they start cleaning up after themselves. There’s communicating and then there’s effectively communicating — you want to do the latter.

Before choosing to confront your roommate, Grace says to take a minute and avoid speaking too quickly or too harshly. He suggests taking time to consider your roommate’s point of view and acknowledge their perspective as valid, which doesn’t have to be labelled as better or worse than yours, it’s just a differing perspective.

Corbo adds communication requires confidence and sensitivity. It’s important not to come off aggressively.

“It is one thing to say, ‘It is important to me to have the bed made each day because I feel like it signals the beginning of a new day,’ rather than, ‘I don’t know why you are so lazy and can’t pull up the comforter and blankets when you wake up.’”

She adds that addressing conflict can be uncomfortable and you may stumble in doing so. That’s OK.

 

It is not awkward

 

Confrontation may appear to be awkward because people often view confrontation as a negative thing, but it doesn’t have to be that way says Grace.

She notes something psychologists call the “liking gap”, which she says people think that other people like them less after a conversation.

“This can lead people to feel awkward or disliked, when in reality almost everyone underestimates how much the other person actually likes them,” Grace says. “Thus, more than we realise, our roommates probably like us more than we know, even when we have the inevitable, difficult conversation about differences.”

You also may need alone time to recover from a disagreement if it didn’t go as smoothly as planned.

“Learning to feel comfortable with a friend or roommate after a conflict requires maturity, humility and humour,” says Corbo. “Alone time may be necessary to recalibrate after a conflict but don’t avoid your roommate for too long. This extends the period of awkwardness and that can make the problem worse.”

Nissan Patrol V8 Platinum: Big beast of the Middle East

By - Sep 30,2019 - Last updated at Sep 30,2019

Developed primarily for its biggest market, the latest iteration of Nissan’s behemoth Patrol SUV launched globally in Abu Dhabi last week. Building on a tried and tested recipe, the latest Patrol is as abundant in size, space, ability, equipment and output as its predecessor, and is sure to retain its segment leading position as a big family daily driver in the GCC. 

Less common, but still a regular sight in Jordan, the latest Patrol remains a reliable and more attainable alternative to other big luxury SUVs. 

Descended from a long line of tough utilitarian off-roaders that grew in size and comfort since 1951, the latest Patrol is the most refined, road-friendly and advanced yet. But with body-on-frame construction and extensive off-road hardware, it is just as happy on the school run as it is through the rugged outdoors. Luxurious but not too “precious”, exotic or delicate for actual off-road adventuring, the Patrol comes with escalating levels of luxury specifications, V6 or V8 engine options, and two new bumpers options for urban or off-road driving.

 

Edgy evolution

 

Dwarfing many SUVs, the hulking Patrol’s latest iteration is heavily redesigned — front and rear — despite a near identical silhouette and side views. Adopting a sharper and more upright fascia with a bigger and lower interpretation of Nissan’s V-motion grille, it also features deeper side intakes, more prominent lower lip and slim C-shaped LED lights that interlock with a sharply edged fascia frame. At the rear it gains more mature and stylish lights, and a full length chrome strip to emphasise its width and hunkered down stance.

Unchanged underneath its substantial bonnet, the range-topping Patrol’s naturally-aspirated direct injection 5.6-litre V8 engine drives all four wheels with default but variable rear-bias. 

Developing a mighty 400HP at 5800rpm and 413lb/ft torque at 4000rpm (gross), delivery is prodigiously progressive, with distantly subdued bellows and burbles. It nevertheless produces generous low-end and mid-range torque to hustle the Patrol’s 2.8-tonne mass at a lively pace, including an estimated 6.5-second 0-100km/h time. 

Providing good throttle control, the Patrol’s 7-speed automatic gearbox can meanwhile be operated in manual mode through the gear lever.

 

Reassuring ride

 

Riding on sophisticated double wishbone suspension with hydraulic dampers to curb squat and dive and provide level body control and supple ride comfort, the Patrol is in its element on highway. 

Developed with GCC roads and fast wide-angle curves in mind, it felt settled, comfortable and reassuring on 160km/h Abu Dhabi stretches. Not the most nimble through tightly winding hillclimbs, the Patrol is, however, more easily hustled through narrower, more flowing roads, where shifting weight out and rearwards tightens cornering lines and negates a slight instinct for understeer.

Refined and quiet inside, and buttoned down over bumps, the Patrol smoothly irons out road imperfections, despite low profile 275/60R20 tyres. 

Manoeuvrable and easy driving in town for its size due to a relatively big glasshouse, reversing camera, parking sensors and big door mirrors, it also benefits from light steering, which seems might have gained slight heft and nuance over its predecessor. Its steering nevertheless develops more road feel when loaded up through hard driven corners, while brakes proved reassuringly fade resistant on descent from Jebel Hafeet. 

 

Rugged yet refined

 

Driving through sandy flat desert routes with ease in default driving mode, the Patrol’s Terrain Mode driving selector can optimise various parameters for different conditions. Also fitted with electronic hill descent control, the Patrol’s extensive suite of off-road hardware more importantly includes low ratio four-wheel-drive for steep crawling speeds, locking rear differential for very low traction conditions, generous 275mm ground clearance and 28 degree approach and 26.3 degree departure angles. Approach angle improves to 34 degree when fitted with optional off-road bumper, while entry-level 18-inch alloy wheels are also available.

Handsome and abundantly spacious for passengers and cargo, the 8-seat Patrol features numerous improvements inside. Making extensive use of soft textures, quality materials and sturdy build quality, the new Patrol also introduces classy new diamond quilted GT-R Tan leather upholstery — inspired by its supercar stablemate — and improved side seat bolstering, enhanced ventilation and a much improved dual stacked screen infotainment system. Generously equipped with convenience, safety and driver assistance systems, the new Patrol also now features pedestrian detection capability to its Intelligent Emergency Braking and collision prevention system.

Intrusive, unwanted thoughts

Clinical Psychologist

 

Do you find yourself constantly going back to check if you locked your front door or the car? People with obsessive thoughts and compulsive behaviours that interfere with daily life have Obsessive Compulsive Disorder (OCD). 

 

What is OCD?

 

OCD is an anxiety disorder in which people have recurring, unwanted thoughts, ideas, or sensations (obsessions) that make them feel driven to do something repetitively (compulsions), which interfere with a person’s daily activities and social interactions, according to the American Psychiatric Association. These obsessions and compulsions can be time consuming and very exhausting to the person experiencing them. Rituals like checking, washing and cleaning are most common types of OCD, and are done to relieve the anxiety resulted by the obsessive thoughts.

 

Causes of OCD

 

Causes of OCD have not been identified but genetics and having a predisposition to develop OCD symptoms may be a factor along with environmental factors, such as childhood abuse, neglect, psychological and physical trauma, big life events like marriage, divorce and moving out.

 

Basic types of OCD

 

OCD patients may experience more than one type of OCD:

 

• Checkers: Those who feel compelled to repeatedly check objects; doors, locks, ovens and other appliances at home, or even checking in on their loved ones

• Washers and cleaners: Obsessions about contamination by germs, dirt and viruses 

• Orders and repeaters: Those who keep repeating particular actions or thoughts like prayers or arranging items in a specific perfect way

• Pure obsessionals: Some people experience sexual or aggressive obsessions that involve causing harm to others. They are mortified by such thoughts and, as a result, work very hard to suppress or push them away

• Hoarders: Those who collect unimportant items and face difficulties throwing them away, developing a strong attachment to these items while having the fear of needing them if thrown away

• People with scrupulosity: Those who have religious or ethical obsessions, being preoccupied with doing the right thing

 

Treatment options for OCD

 

The most effective treatment is Exposure and Response Prevention, a cognitive behavioural therapy that focuses on cognition and behaviour:

• The cognitive part is mainly focused on the faulty beliefs (the obsessions) the individual is experiencing

• The behaviour part includes exposing the individual to experience anxiety, provoking situations in a gradual process under the supervision of a psychologist

Medication can be prescribed to OCD patients to reduce the stress resulted by obsessions. However, a combination of both medication and cognitive behavioural therapy can be very helpful in breaking free from OCD symptoms.

Don’t hesitate to seek professional help if you have obsessions or compulsions that affect your daily life. Seeking professional help and enlisting the support of loved ones is very important to getting better.

A frightening loss of habitat

Companions in Conflict: Animals in Occupied Palestine

Penny Johnson

Brooklyn-London: Melville House, 2019

Pp. 238

 

“Companions in Conflict” approaches Palestine from a totally new angle: animal welfare and its relationship to human welfare. The author, Penny Johnson, is a veteran activist for justice for the Palestinians. She has lived in Ramallah since the early 1980s, working as a human rights advocate, researcher and founding member of the Institute of Women’s Studies at Birzeit University, and writer/editor of numerous publications on Palestine.

In the introduction, she names “two particular measures… that led me to think about the lives of animals other than humans in this fragile land: times of walking and times of war”. (p. x)

With an expansive empathy for both human and animal suffering and dilemmas, a commitment to truth, and elegant prose, Johnson conveys her careful observations and research into Palestine’s fauna. 

Johnson has walked the land in many parts of Palestine, particularly the West Bank, and spoken with Palestinian farmers, bedouin and environmentalists. Her most frequent companion on these forays was her husband, Raja Shehadeh, the well-known Palestinian human rights lawyer, who has also written about walking in books such as “Palestine Walks” and “A Rift in Time”. 

Starting with the camel, the book devotes chapters to domesticated animals such as goats, sheep, donkeys and cows, considered useful by humans. Also explored is the status of wild animals from the beautiful gazelle and ibex, to others which are feared or considered threats, like hyenas, wild boars, wolves and jackals. For each species, Johnson traces its history in Palestine, as well as attitudes, fables and literature attached to it, often spiced with absurd or amusing anecdotes. 

There is the camel arrested by Israeli police in Jerusalem for not having a permit, and Beit Sahur’s dairy cows being declared dangerous to the state of Israel by the military governor, both clear parallels to human experience under the occupation. Then, there is Israeli Prime Minister Netanyahu bragging that “a Jewish cow… a computerised cow” produces more milk than any other cow, in an odd confusion of terms. (p. 122)

It soon becomes clear that Johnson is not more concerned about animals than people. To her, it is not a zero-sum game but a question of interdependence: “I am all too aware of what we humans, Palestinians and those of us who live in Palestine, have in common with other mammals: a disturbing, even frightening loss of habitat. I explore how the lives of animals help us understand what is happening to all of us...”
(pp. xii-xiii) 

Just as Israeli land confiscation and settlements deprive Palestinians of their homes and livelihood, the patterns of animal life are disrupted. In addition to climate change, drought and rapid urbanisation that are affecting much of the world, it is the occupation’s land-and-water-grabbing measures that are most often found to be the reason for the diminishing number of animals, whether wild or domesticated. Israel’s electronic fence along Gaza deters animal as well as human circulation, and blocks access to water sources, as does the Wall itself. One species reported to be on the rise is the wild boar, which B’tselem attributes to “raw sewage runoff from the massive settlement complex of Ariel polluting water sources near Salfit and killing other wildlife while drawing wild pigs to its delicious detritus”. (p. 136) 

There are many other violations. Obviously, when curfews or military attacks threaten human lives and food supplies, the same applies to animals. Johnson also points out harmful Palestinian practices, such as unregulated hunting. Crucially, she shows how the occupation’s unhuman treatment of humans makes it difficult for Palestinian animal welfare advocates to plead their case. Here irony abounds: “It is no wonder that many Palestinians, even those concerned with the environment and animal welfare, are cynical about Israeli environmentalists advocating passage for animals, but not people, through the Separation Wall.” (p. 43) 

Another example came in 1916, when an international animal welfare organisation rescued a Bengal tiger named Laziz from “the worst zoo in the world” in Khan Younis, at a time when, as now, neither people nor products could easily get out of Gaza even for much needed medical treatment. “Gazans have a right to wonder [and, as is their wont, to joke] why Laziz’s life is valued over theirs.” (p. 199)

Johnson’s wholistic outlook on how humans could potentially interact with, benefit from and enjoy nature, including animals, courses throughout “Companions in Conflict”. She tells a story that has not been told before and which needs to be told, and which is especially timely as environmental issues gain more and more international urgency. Her tone is one of genuine inquiry. She has no ax to grind except for concern about the future of Palestine, its people and its nature, which she sees as interlinked. Though she is never polemical, the facts she presents reconfigure a discussion that Israel has tried to monopolise by presenting its policies as environment-friendly, when in fact its anti-Palestinian policies have wreaked havoc on the land it covets. Johnson also deserves much thanks for bringing to light the serious work of Palestinian environmentalists and the original environmentalists, the farmers and bedouin of Palestine.

 

 

Babies have been drinking milk from bottles for thousands of years

By - Sep 28,2019 - Last updated at Sep 28,2019

By Deborah Netburn 

The vessels are small and ceramic. Some resemble tiny teapots, others look like small pipes, and a few are sculpted into whimsical animal shapes with a little spout on the backside.

When they were discovered in ancient cemeteries scattered across Europe, some archaeologists wondered if they were used to feed the sick or the elderly. But because they were often buried in graves alongside infants, most experts agreed that the vessels likely served a different purpose entirely:

Call them prehistoric baby bottles.

Now, a new chemical analysis of three of these ancient containers provides further evidence that the vessels were indeed used to feed milk from cows, sheep or goats to human babies.

“People have known about these containers for a long time and assumed they were baby bottles, but nobody had done a thorough analysis on them,” said Julie Dunne, a chemist at the University of Bristol in England, who led the work. “What I liked about this study is that it gave us a nice, close connection to parents of the past.”

Dunne works in the university’s Organic Geochemistry Unit, a research group that has chemically analysed roughly 10,000 shards of pottery from around the world to help archaeologists better understand what foods and other materials the artefacts once contained.

Their work has revealed that lipids, the building blocks of fats, can survive for thousands of years.

“What we know from years of experimental work is that fats absorb into the ceramic matrix of the vessel and are often preserved there,” Dunne said. “Because of that, lipids do survive in about 80 per cent of the assemblages we’ve looked at.”

In the new study, Dunne and her colleagues collected samples from three ceramic baby bottles that had been found next to infants in ancient German burial sites. Two of the bottles came from a cemetery complex that scientists believe was in use between 800 and 450 BC; the other bottle was found in a site dated to 1200 to 800 BC. (The earliest-known ceramic baby bottles have been dated to about 5,000 BC.

The researchers had been looking for vessels that had wide openings, so they would be easier to work with. Still, Dunne said that collecting samples from the bottles was a nerve-racking experience.

Usually, her team begins its analysis by grinding up pieces of old cooking pots. But since the small bottles were still intact, that was not an option.

“We had to adopt a modified strategy,” she said.

They cleaned the interior surfaces of the vessels, then drilled out just enough ceramic powder to be able to see any lipids that had been absorbed by the pottery. Next, they used a chemical process to free the lipids from the ceramic matrix, allowing them to measure the chemical and isotopic fingerprint of each one.

Ultimately, they found that the vessels contained fatty acids from dairy products — almost certainly milk — that came from domesticated ruminant animals, according to their report in the journal Nature. They were not able to tell if the milk came from cows, sheep or goats.

The work represents “the earliest known evidence of animal milk in small bottles for infants,” Sin Halcrow, a bioarchaeologist at the University of Otago in New Zealand, wrote in an essay accompanying the paper.

Halcrow, who was not involved in the study, added that the work also “provides crucial insight into the diet of developing infants in prehistoric human populations”.

Dunne said she hopes the new work will lead to a much larger study that will apply the same kinds of analytic tools to ceramic baby bottles across a larger geographical area.

“We know the ancient Greeks were using similar vessels, also the Romans, and some have been found in prehistoric Sudan in north Africa,” she said. “It would be fantastic to do a really large-scale study to see if they are always used to hold milk or if they had other foods processed in them.”

The authors noted that while breast milk has always been integral to infant care across history and cultures, there is considerable variation among human societies as to when new foods are introduced and how long a child continues to get nutrition directly from mom.

For example, archaeologists have found that hunter-gatherers typically breastfed for several years, whereas the more sedentary lifestyle of early farming communities allowed mothers to stop nursing earlier because other foods were more readily available.

It is possible that this shorter weaning period may also have led to shorter birth intervals between children, the authors wrote. That, in turn, could have contributed to the considerable growth in population known as the Neolithic demographic transition.

Dunne and her fellow researchers were curious to see how a modern-day infant would respond to a replica of one of the ancient bottles, so they recruited the baby of one of their friends.

The rounded shape of the prehistoric bottle fit perfectly in the young child’s hands. The scientists poured in some milk and tipped a bit of it into the baby’s mouth. The baby quickly started sucking the spout to get a bigger drink.

The ancient baby bottle technology still worked.

Teens flock to flavoured vaping which hides grave health dangers

By - Sep 28,2019 - Last updated at Sep 28,2019

By Soumya Karlamangla 

LOS ANGELES — High schoolers rallying in downtown Los Angeles this week chanted “Fight the flavour” as they showed their support for banning the flavoured tobacco products that health experts say are fuelling an epidemic of nicotine addiction among youths.

Among the demonstrators was Jennyfer Cortez, 16, who said she tried an e-cigarette for the first time five years ago because it tasted like blueberries, her favourite fruit. She didn’t like vaping because it made her cough, but she has seen her peers vape at their lockers, in the school bathroom and sometimes even in class.

“These kids are so addicted to nicotine, they can’t go one class period without vaping,” said Cortez, a junior at Ánimo Jackie Robinson Charter High School in South L.A.

Governments around the nation are considering banning flavoured tobacco products amid burgeoning e-cigarette use among youths and a mysterious outbreak of a serious lung disease that appears to be linked to vaping. The legislative efforts would eliminate the fruity e-cigarette pods with flavours such as mango, strawberry and mint, which public health experts say are giving nicotine a foothold among youths.

Many of the regulations, including the one being considered by Los Angeles County officials that drew demonstrators to downtown L.A. on Tuesday, would also outlaw menthol cigarettes. Public health experts say the marketing and sustained popularity of menthol cigarettes provide a window into the playbook that e-cigarette companies could be using when it comes to selling flavoured nicotine products.

Menthol cigarettes, which were invented in the 1920s, were promoted as healthier than regular cigarettes, despite being more dangerous, experts say.

Aggressive marketing of menthol cigarettes to African Americans worked — approximately 85 per cent of African American smokers now prefer menthols, said Phillip Gardiner, a researcher with the University of California’s Tobacco-Related Disease Research Programme.

Over the last century, attempts to ban menthols have failed, because of lobbying by the tobacco industry as well as the cigarettes’ ubiquity, experts say. The Trump administration announced a proposal last year to take them off the market, but the effort appears to have stalled.

“Menthol is the ultimate candy flavour — it helps the poison go down easier,” Gardiner said.

Youths are experimenting with flavoured e-cigarettes; from 2017 to 2018, e-cigarette usage among high schoolers jumped 78 per cent, according to the US Centres for Disease Control and Prevention. E-cigarette devices work by heating a liquid cartridge containing nicotine, and perhaps an added flavour, and turning it into a vapour the user can inhale.

This month, Michigan became the first state in the nation to ban flavoured e-cigarettes. The Trump administration said this month that it is also considering outlawing the products.

The concerns about flavoured tobacco products mirror those about menthol cigarettes, which are flavoured with a mint extract and have served as a gateway to addiction for almost a century, experts say.

“Tobacco companies have known this for a very long time…. Nicotine on its own is really bitter tasting, it does not taste good at all,” said Thomas Ylioja, a tobacco cessation expert at National Jewish Health, a research hospital in Denver. “As a former youth smoker myself, menthol was how I got started.”

Legend has it that in 1925, a man named Lloyd “Spud” Hughes placed his tobacco in a baking powder tin along with menthol crystals, which he was using to treat a cold. The next day, he rolled his tobacco and accidentally created a menthol cigarette.

Over the following decades, many companies began selling menthols, marketing them as a less harsh alternative to traditional cigarettes.

Tobacco executives noticed a slight preference for menthols among African Americans and began targeting them with advertising. Popular menthol brand Kool hired Elston Howard, an African American catcher for the New York Yankees, as a spokesman, and cigarette companies bought ads in Ebony magazine. Predictably, the percentage of black people smoking menthols skyrocketed, according to a paper Gardiner wrote detailing what he calls the “African Americanisation of menthol cigarette use”.

“Unfortunately, the tobacco industry efforts have been very successful,” Gardiner said in an interview.

Menthol not only makes tobacco taste better, it also numbs the throat so people can smoke more cigarettes, he said. Worse, menthol allows for deeper inhalation of the smoke, which lets more nicotine into the body, which makes people more addicted, he said.

In 2009, a federal law outlawed many flavoured cigarettes, such as chocolate and vanilla, but not menthol. The long-term success of menthols paved the way for flavoured e-cigarettes, said Bill Novelli, former president of the Campaign for Tobacco-Free Kids.

“It seems pretty clear that these flavours were basically created to seduce and entice kids into smoking,” he said.

The results of a survey conducted by the American Heart Assn. of 1,500 adult e-cigarette users published this month found that nearly a third of adults who use e-cigarettes said a primary reason they started was because of the flavours. That percentage was even higher among young adults, according to the survey.

“The flavouring in these nicotine products attracts younger people at a time when they are most likely to become addicted if they try it,” said Dr Jessica Sims with the American Heart Association.

However, those opposed to banning flavoured e-cigarettes say they offer a way for smokers to switch to a safer alternative. Experts agree that despite the risks of e-cigarettes, they remain less dangerous than traditional cigarettes.

At the rally outside the LA County Board of Supervisors meeting Tuesday, people shouted “Save our vapes” over the high schoolers.

Alan Ngo, 32, held a sign that said, “I Vote, I Vape”. Four years ago, he switched from smoking to vaping, the only thing that helped him quit traditional cigarettes, he said. He said his lungs feel better than they did before. He is able to run farther and he coughs less, he said.

“I think the flavours save lives,” said Ngo, who lives in Rosemead.

At the meeting on Tuesday, county supervisors advanced the ban on flavoured tobacco, which would make illegal not only the fruity pods of liquid nicotine and traditional menthol cigarettes, but also mint chewing tobacco and cream cigars, among other products. The ban will affect only unincorporated areas, which include about 1 million people.

Also on Tuesday, Kevin Burns, the chief executive of e-cigarette giant Juul, stepped down. His replacement, K.C. Crosthwaite, said the company would suspend all advertising in the United States and would refrain from lobbying the Trump administration on its proposed ban of flavoured e-cigarette products.

In a statement, Crosthwaite acknowledged the company must work with policymakers and regulators because its “future is at risk due to unacceptable levels of youth usage and eroding public confidence in our industry.”

Mice can reproduce after space stints

TOKYO — Male mice that spent more than a month in space were able to successfully reproduce back on Earth, a study has found, the first evidence of how space travel affects reproduction in mammals.

There have been some signs that spending time in space could negatively affect sperm, including radiation damage seen in freeze-dried mouse sperm that spent nine months in outer space, and decreased sperm counts in rats that spent 13 days in orbit.

The research examined 12 male mice who spent 35 days aboard the International Space Station in specially designed cages.

Some of the mice experienced the weightlessness of microgravity, while others were in cages designed to offer artificial gravity.

Upon their return to Earth, the researchers used sperm from the mice to fertilise eggs from female mice who had not experienced space travel, and found the astronaut rodents produced healthy offspring.

The team, led by Masahito Ikawa, a professor at Osaka University, also examined the reproductive organs of the space-travelling mice and checked their offspring for any signs that their parentage had negative effects.

“We conclude that short-term stays in outer space do not cause overt defects in the physiological function of male reproductive organs, sperm function and offspring viability,” says the study published on Tuesday in the journal Scientific Reports.

Medical research has already shown that space travel has a variety of negative health effects, including deterioration of muscle and bone mass, as well as cell mutations caused by radiation exposure.

And previous studies have looked at the effects of space travel on the reproductive systems of species including sea urchins and birds.

But the new study is the first to examine the effects of space travel at the molecular level.

The research is only a first foray, however, and does not necessarily indicate how the reproductive systems of human — or indeed female mice — are affected by space travel.

The researchers said they would like to examine aspects including how space travel affects male reproductive hormone levels and genetic expression in reproductive organs.

“The era where people can easily go into space is coming,” the study says.

“Studies of the effects of space environment on the reproductive system are necessary to prevent undesirable effects in the next generation.”

Who is better at the job: Man or machine?

Are self-driving cars safer than manned ones?

The invasion of the cloud and networks, combined with the extraordinary breakthroughs in high-tech, are constantly increasing the number of automated operations of all kinds. This is causing a relaunch of the old debate about whether man or machine are better at the job. There will probably never be a clear cut answer to this question. Moreover, it greatly depends on which job, which exact task are we talking about.

It may possible to classify the tasks in two categories, in a general, rough manner. The first concerns tasks where a failure would cause human casualties or injuries, like driverless cars for example. The second is about all the rest: online computing, payments, banking, shopping, smart-home management, and so forth, where damage because of a system failure would only harm your pocket, cause delays or inconvenience, and where it is always possible to go back and to fix things.

Recent reviews found online about driverless cars are emphasising the fact that they are not only more convenient but and before all safer. In other words the risk that an unmanned car would be in an accident is much, much lower than if a human was driving it. When you analyse all the potential “weaknesses” that would make a person to cause a car accident you cannot but agree.

Some even consider that “driving a car is much too dangerous a task to be left to a person”. In a way it sounds a little bit like the famous line by French statesman Georges Clémenceau who once said: “War is too serious a matter to entrust to military men.” Both statements sound like blatant contradictions at first sight, but not at second thought!

An impressive and deeply moving medical documentary was broadcast last week on CBC — Radio Canada TV channel. It showed a pioneering technology that uses laser and heat to kill and remove a cancerous brain tumour in a child. It involved no chemical product of any kind, and the cured young boy was able to get up and go home on the very next day following the surgery!

The surgeon explained that it was made possible only thanks to high-tech. First there was the precision of the laser beam, of course, and then the software especially developed for the operation and that would do most of the work by itself by guiding the laser beam, setting the heat point, etc.

He added that the software programme was so complex and difficult to use that the company that designed it would always keep three software engineers with the surgical team, to help them use it properly. This is a typical case where the machine, a system of computers and programming in this very case, are beyond any possible doubt better than man at the job.

Whether in vital or in non-vital cases, there will always be machine failures. We have all seen the tragic consequence of air crashes caused by technical issues. These will sometimes be impossible to predict or even to address, and unfortunately there will also be times when machine or system failures would happen because of human errors, a job poorly done or bad software programming, not to mention extreme cases of intentional hacking or criminal attacks, made by man but through the machines and the systems.

Despite the above, I would trust the machine much more than people, if only in the example of the upcoming driverless cars. At least a self-driving vehicle would never be talking on the phone or texting, would not be particularly nervous and unstable because of a domestic fight at home in the morning, certainly would not be drunk, would be focusing on driving and on driving only, and would perfectly comply with traffic regulations, speed limits and road signs. As for the possible technical failures, they will be fewer, much fewer than human failures.
