The London Marathon Gave Out These Water Bubble Pods, Replacing 200,000 Water Bottles

Here's something to chew on. Can a gulp of water help save the planet? If you're drinking *and* eating your water at the same time, the answer may be yes.
The tasteless packaging is made from brown seaweed that biodegrades naturally in four to six weeks.
The Lowdown
A start-up company called Skipping Rocks Lab has created a "water bubble" encased in an edible sachet that you can pop in your mouth whole. Or if you're not into swallowing it, you can tear off the edge, drink up, and toss the rest in a composter. The tasteless packaging is made from brown seaweed that biodegrades naturally in four to six weeks, whereas plastic water bottles can linger for hundreds of years.
The founders of the London-based company are determined to "make plastic packaging disappear." They had two foodie inspirations: molecular gastronomists and fruit. They tried to emulate the way chefs used edible membranes to encase bubbles of liquid to make things like fake caviar and fake egg yolks; and they also considered the peel of an orange or banana, which protects the tasty insides but can be composted.
The sachets can also contain other liquids that come in single-serve plastic containers -- think packets of condiments with takeout meals, specialty cocktails at parties, and especially single servings of water for sporting events. The London Marathon last month gave out the water bubble pods at a station along the route, using them to replace 200,000 plastic bottles that would have likely ended up first in the street, and ultimately in the ocean.
Next Up
The engineers and chemists at Skipping Rocks intend to lease their machines to others who can then manufacture their own sachets on-site to fill with whatever they desire. The new material, which is dubbed "Notpla" (not plastic), also has other applications beyond holding liquids. It can be used to replace the plastic lining in cardboard takeout boxes, for example. And the startup is working on additional materials to replace other types of ubiquitous plastic packaging, like the netting that encases garlic and onions, and the sachets that hold nails and screws.
Edible water bubbles may be the future of drinks at sporting events and festivals.
Open Questions
One hurdle is that the pods are not very hardy, so while they work fine to hand out along a marathon route, they wouldn't really be viable for a hiker to throw in her backpack. Another issue concerns the retail market: to be stable on a shelf, they'd have to be protected from all that handling, which brings us back to the problem the engineers tried to solve in the first place -- disposable packaging.
So while Skipping Rocks may not achieve their ultimate goal of ridding the world of plastic waste, a little progress can still go a long way. If edible water bubbles are the future of drinks at sporting events and festivals, the environment will certainly benefit from their presence -- and absence.
Saliva May Help Diagnose PTSD in Veterans
A recent study finds that former soldiers with post traumatic stress disorders have a certain set of bacteria in their saliva, a distinct signature that is believed to be the first biological marker for PTSD.
As a bioinformatician and young veteran, Guy Shapira welcomed the opportunity to help with conducting a study to determine if saliva can reveal if war veterans have post-traumatic stress disorder, or PTSD.
The research team, which drew mostly from Tel Aviv University’s Sackler Faculty of Medicine and Sagol School of Neuroscience, collected saliva samples from approximately 200 veterans who suffered psychological trauma stemming from the years they spent fighting in the First Lebanon War in 1982. The researchers also characterized the participants’ psychological, social and medical conditions, including a detailed analysis of their microbiomes.
They found that the former soldiers with PTSD have a certain set of bacteria in their saliva, a distinct microbiotic signature that is believed to be the first biological marker for PTSD. The finding suggests that, in the future, saliva tests could be used to help identify this disorder. As of now, PTSD is often challenging to diagnose.
Shapira, a Ph.D. student at Tel Aviv University, was responsible for examining genetic and health-related data of the veterans who participated – information that had been compiled steadily over four decades. The veterans provided this data voluntarily, Shapira says, at least partly because the study carries important implications for their own psychological health.
The research was led by Illana Gozes, professor emerita of clinical biochemistry. “We looked at the bacteria in their blood and their saliva,” Gozes explains. To discover the microbial signatures, they analyzed the biometric data for each soldier individually and as a group. Comparing the results of the participants’ microbial distribution to the results of their psychological examinations and their responses to personal welfare questionnaires, the researchers learned that veterans with PTSD – and, more generally, those with significant mental health issues – have the same bacterial content in their saliva.
“Having empirical metrics to assess whether or not someone has PTSD can help veterans who make their case to the Army to get reparations,” Shapira says.
More research is required to support this finding, published in July in Nature’s prestigious Molecular Psychiatry, but it could have important implications for identifying people with PTSD. Currently, it can be diagnosed only through psychological and behavioral symptoms such as flashbacks, nightmares, sleep disorders, increased irritability and physical aggressiveness. Veterans sometimes don’t report these symptoms to health providers or realize they’re related to the trauma they experienced during combat.
The researchers also identified a correlation that indicates people with a higher level of education show a lower occurrence of the microbiotic signature linked to PTSD, while people who experienced greater exposure to air pollution show a higher occurrence of this signature. That confirms their finding that the veterans’ health is dependent on their individual biology combined with the conditions of their environment.
“Thanks to this study, it may be possible in the future to use objective molecular and biological characteristics to distinguish PTSD sufferers, taking into account environmental influences,” Gozes said in an article in Israel21c. “We hope that this new discovery and the microbial signatures described in this study might promote easier diagnosis of post-traumatic stress in soldiers so they can receive appropriate treatment.”
Gozes added that roughly a third of the subjects in their study hadn’t been diagnosed with PTSD previously. That meant they had never received any support from Israel’s Ministry of Defense or other officials for treatment and reparations, the payments to compensate for injuries sustained during war.
Shapira’s motivation to participate in this study is personal as well as professional: in addition to being veteran himself, his father served in the First Lebanon War. “Fortunately, he did not develop any PTSD, despite being shot in the foot...some of his friends died, so it wasn’t easy on him,” says Shapira.
“Having empirical metrics to assess whether or not someone has PTSD can help veterans who make their case to the Army to get reparations,” Shapira says. “It is a very difficult and demanding process, so the more empirical metrics we have to assess PTSD, the less people will have to suffer in these committees and unending examinations that are mostly pitched against the veterans because the state is trying to avoid spending too much money.”
