Devising renewable sources of energy is a key concern for scientists, political leaders and communities as the world comes to terms with the realities of climate change and the limits of the Earth’s natural resources. In an exciting new development, scientists from the Institute of Scientific and Industrial Research (SANKEN) at Osaka University have demonstrated that electricity may be obtainable from water with a high salt concentration, such as seawater.
Some people think about “osmosis” as just a science term they were forced to learn in elementary school biology class. However, the spontaneous motion of dissolved ions or molecules through a semi-permeable membrane when there is a concentration difference between the two sides can be harnessed to generate electricity. And luckily for us, the oceans are filled with salty water, which may be used to help alleviate humanity’s ever-growing demand for energy. However, in order to be practical, this membrane needs to be very thin and highly selective to allow ions—but not water molecules—to pass through.
Now, a research team led by Osaka University has used conventional semiconductor processing technology to precisely control the structure and arrangement of nanopores in an ultrathin silicon membrane. Because these fabrication methods have been around for decades, the costs and design complexities were minimized. Moreover, the size and location of the pores could be precisely controlled.
“Whenever there is a non-equilibrium situation, such as two water tanks with different salt concentrations, there is often an opportunity to covert this thermodynamic energy into electricity,” says first author Makusu Tsutsui.
Using a single 20-nm-sized nanopore, the device reached a peak power efficiency of 400 kW/m2. However, the researchers found that adding too many nanopores to the membrane actually reduced the power that could be extracted. The optimal configuration of pores, 100-nm-sized nanopores arranged in a grid with a spacing of one micrometer, yielded an osmotic power density of 100 W/m2.
This was an important step in understanding how to design nanopore devices for best power generation. “Many other research groups are promising environmentally friendly ‘green’ energy, but we go one step further and propose ‘blue’ energy based on oceanwater that can be applied on an industrial scale,” senior author Tomoji Kawai says. The study is published in Cell Reports Physical Science, and future projects may include ways to scale up the devices for real world testing.
Will silicon nitride and common chemistry help revolutionize genomic sequencing?

Britney Spears Gifts Elton John Adorable Salt & Pepper Shakers – Billboard
Britney Spears shared her gratitude for Elton John and the success of their “Hold Me Closer” duet with the sweetest gift.
John took to Twitter on Friday (Sept. 2) to share the rocket-shaped salt and pepper shakers that the pop princess gifted him. “Thank you @britneyspears for the fabulous rocket salt and pepper shakers!! David [Furnish] and I love them,” the “Rocketman” himself captioned the photo.

“She did it so well and so easily,” the music icon continued of their collaboration. “And I’m sure a lot of people thought, ‘Well, can she still sing?’ Well, I knew for a start that she could sing because if you go back and look at the old footage, she was the biggest artist in the world and she could sing, she could dance, she could do everything. So I wasn’t worried about that. What I was worried about is if she would be so nervous because she hadn’t done it for a while, but she came through it with flying colors.”
“Hold Me Closer,” which is a fresh take on John’s 1972 classic “Tiny Dancer” produced by Grammy winner Andrew Watt, features John and Spears singing the opening verse of John’s 1992 hit, “The One” over a club-ready beat, before diving into the chorus of 1971’s “Tiny Dancer.”
“Hold Me Closer” is Spears’ first new music since her 2016 studio album Glory, which also included deluxe tracks “Mood Ring,” “Swimming in the Stars” and the Backstreet Boys-assisted “Matches” that were released in 2020. Most notably, the collaboration will mark Spears’ official return to music since the end of her 13-year conservatorship.
Over the weekend, Spears posted an unfiltered, 22-minute voice memo on YouTube about her life post-conservatorship and the heartbreaking ways in which the legal control over her life has impacted her mental health, self-confidence and relationship with her family.
A Single Gram of Salt Is The Difference For Millions of Heart Attacks : ScienceAlert
We know consuming too much salt raises blood pressure, which in turn can lead to cardiovascular problems. A new study has now quantified this relationship as a public health message in clear, stark terms.
Looking at health data on adults in China, the study authors estimate that a reduction of just 1 gram in daily salt intake would be enough to prevent 9 million cases of stroke and heart attack between now and 2030.
With 4 million of those cases likely to be fatal, such a simple measure could save a lot of lives.
In China, average daily salt consumption sits at 11 grams, way above the 5 grams recommended by the World Health Organization (WHO). The researchers pulled together the latest stats on population size, salt consumption, blood pressure and disease rates.
“Previous estimations of the health impact of reducing salt intake in China used either obsolete or otherwise unreliable data sources and did not account for the more prolonged effect of salt reduction on blood pressure over several years,” write the researchers in their published paper.
The team looked at two other scenarios besides the single gram drop: a reduction of 3.2 grams per day (a 30 percent drop from the average) by 2025, and reducing salt intake to the recommended 5 grams per day by 2030.
If those targets are hit, up to twice as many deaths related to cardiovascular disease could be prevented, due to the estimated reduction in systolic blood pressure.
However, the researchers emphasize that the reduction would have to be consistent over several years. Education programs run in Chinese schools suggest most of the population wouldn’t find it too difficult to hit that 1 gram per day target.
“Other trials, on low-sodium high-potassium salt substitutes, health education to home cooks and restaurant interventions are ongoing or have recently been completed, some of which have already shown promising results,” write the researchers.
Cardiovascular disease accounts for a massive 40 percent of deaths in China, with urbanization – and the associated increase in eating processed and takeaway foods – thought to be one of the main contributing factors.
While the authors of this study only looked at a potential reduction in cases of cardiovascular disease, they suggest that lowering salt intake would have multiple other benefits too. Too much salt has also been linked to certain types of cancers and various kidney problems, for example.
The Chinese government has launched a Healthy China 2030 campaign to try to hit its target of a daily salt intake of just 5 grams. That won’t be easy with a population of 1.4 billion people, but the numbers produced in this study are compelling.
“A salt reduction programme that is workable, coherent, sustainable and targeting current and upcoming major dietary sources of salt in China is urgently needed,” write the researchers.
The research has been published in BMJ Nutrition, Prevention & Health.
Research Shows Salt Substitutes Lower Risk of Heart Attack/Stroke and Death
A pooled data analysis of the available evidence finds that dietary salt substitutes lower the risk of heart attack, stroke, and death from all causes and cardiovascular disease.
Researchers say beneficial effects likely to apply to people everywhere.
According to a pooled data analysis of the available evidence, dietary salt substitutes lower the risk of heart attack, stroke, and death from all causes and cardiovascular disease. The findings were published on August 9 in the BMJ journal Heart.
The researchers believe that the beneficial effects of these substitutes are likely to apply to people all around the world.
High blood pressure is a significant risk factor for an early death, and cardiovascular disease is the leading cause of mortality globally. A diet high in sodium and low in potassium is known to increase blood pressure.
Around 1.28 billion people around the world have high blood pressure, although more than half of these are undiagnosed, according to the researchers.
Salt substitutes, which replace a proportion of sodium chloride (NaCl) with potassium chloride (KCl), are known to help lower blood pressure.
A recently published large study from China (Salt Substitute and Stroke Study; SSaSS) found that salt substitutes cut the risk of heart attacks, stroke, and early death. However, it was unclear whether these benefits would apply to other parts of the world.
In an effort to shed light on this, the scientists trawled research databases looking for randomized clinical trials published up to the end of August 2021 that reported on the effects of a salt substitute on blood pressure, cardiovascular health, and early death.
Blood pressure, which is measured in mm Hg, is made up of two numbers: systolic—the higher number that indicates the force at which the heart pumps blood around the body; and diastolic—the lower number that indicates arterial pressure when the heart is filling with blood.
They pooled the results of 21 relevant international clinical trials involving nearly 30,000 people. These were carried out in Europe, the Western Pacific Region, the Americas, and South-East Asia.
The study periods lasted from 1 month to 5 years. The proportion of sodium chloride in the salt substitutes varied from 33% to 75%; the proportion of potassium ranged from 25% to 65%.
According to the pooled data analysis, salt substitutes lowered blood pressure in all the participants. The overall reduction in systolic blood pressure was 4.61 mm Hg and the overall reduction in diastolic blood pressure was 1.61 mmHg.
Reductions in blood pressure seemed to be consistent, irrespective of geography, age, sex, history of high blood pressure, weight (BMI), baseline blood pressure, and baseline levels of urinary sodium and potassium.
And each 10% lower proportion of sodium chloride in the salt substitute was associated with an additional 1.53 mm Hg drop in systolic blood pressure and an additional 0.95 mm Hg drop in diastolic blood pressure. There was no indication that consuming more potassium was harmful to one’s health.
A pooled data analysis of the results of five of these trials involving more than 24,000 participants showed that salt substitutes lowered the risks of early death from any cause by 11%, from cardiovascular disease by 13%, and the risks of heart attack or stroke by 11%.
The scientists acknowledge certain limitations to their findings, including that the studies in the pooled data analysis varied in design and that there were relatively few data for people who didn’t have high blood pressure.
But they nevertheless highlight that their findings echo those of the SSaSS, the largest ever trial of a potassium-enriched salt substitute to date.
“Since blood pressure lowering is the mechanism by which salt substitutes confer their cardiovascular protection, the observed consistent blood pressure reductions make a strong case for generalisability of the cardiovascular protective effect observed in the SSaSS both outside of China and beyond,” the authors write.
“These findings are unlikely to reflect the play of chance and support the adoption of salt substitutes in clinical practice and public health policy as a strategy to reduce dietary sodium intake, increase dietary potassium intake, lower blood pressure and prevent major cardiovascular events,” the researchers conclude.

Switching out salt for another seasoning could add years to your life, study reveals
LONDON — Sprinkling salt substitutes on meals could add years to your life, according to new research. A global study found opting for a seasoning other than salt lowers the risk of premature death from cardiovascular disease or any cause by more than 10 percent.
They also reduce heart attacks and strokes by 11 percent. Consuming too much salt can lead to clotting, cutting off blood supply to major organs. Salt replacements taste just like the real thing and are widely available in supermarkets.
They also contain added potassium and less sodium, protecting against high blood pressure, according to the international team.
“The magnitude of the cardiovascular protection afforded is likely to be determined by the magnitude of the fall in blood pressure,” the study authors write in the journal Heart.
“Blood pressure-mediated beneficial effects of salt substitute on clinical outcomes appear likely to be accrued across a broad range of populations without adverse effects.”
“These findings are unlikely to reflect the play of chance and support the adoption of salt substitutes in clinical practice and public health policy as a strategy to reduce dietary sodium intake, increase dietary potassium intake, lower blood pressure and prevent major cardiovascular events,” the researchers add in a media release.
How helpful are substitutes for blood pressure?
The findings come from the results of 21 clinical trials involving nearly 30,000 people in Europe, the Western Pacific Region, the Americas, and South-East Asia. Salt substitutes lowered blood pressure among all participants.
Overall, systolic (top number) and diastolic (bottom number) readings dropped by 4.61 and 1.61 mm/Hg, respectively. The former reflects the heart’s force when it pumps and the latter when it rests between beats. Major organs are vulnerable to stress if either blood pressure number is too high.
Each 10 percent lower proportion of sodium chloride displayed a connection to a 1.53 and 0.95 mm/Hg greater fall in systolic and diastolic blood pressure, respectively. Nearly half of all U.S. adults have hypertension, according to the CDC.
Estimates show that around a third of all cases are undiagnosed, with health officials calling it the “silent killer” — as there are few symptoms.
“Excess dietary sodium and insufficient dietary potassium are both well-established causes of high blood pressure,” the team writes. “Randomized trials demonstrate that reduced dietary sodium consumption or potassium supplementation lowers blood pressure.”
“Sodium-reduced, potassium-enriched salt substitutes, in which a proportion of the sodium chloride (NaCl) in regular salt is replaced with potassium chloride (KCl), combine these blood pressure-lowering effects.”
What makes a salt substitute healthy?
The reductions in blood pressure among people using salt substitutes were consistent irrespective of geography, age, sex, history of high blood pressure, body mass index (BMI), and baseline levels of blood pressure, urinary sodium, and potassium. There was no evidence that higher dietary potassium levels led to any harmful effects on health.
Standard table sea or rock salt is virtually 100-percent sodium chloride. In substitutes like LoSalt, up to two-thirds of the sodium is replaced by potassium. The salty tasting mineral is lacking in many people’s diets.
However, the body needs this mineral for healthy muscles and nerves, and for normal blood pressure. Studies have previously linked the supplements to lower blood pressure. A quarter-teaspoon serving of Lo Salt contains 450mg potassium, 23 percent of an adult’s daily required amount.
Western diets are high in processed food that already contain high levels of salt, a habit which has prompted calls for the food industry to switch to low-sodium salt as well.
“Since blood pressure lowering is the mechanism by which salt substitutes confer their cardiovascular protection, the observed consistent blood pressure reductions make a strong case for generalizability of the cardiovascular protective effect observed in the SSaSS both outside of China and beyond,” researchers conclude.

Swapping salt for substitutes reduces risk of stroke and heart conditions – study | Heart disease
Replacing regular salt with a salt substitute lowers blood pressure and protects against life-threatening heart conditions, stroke and death from all causes, research suggests.
High consumption of salt composed of sodium chloride is known to drive blood pressure up, leading to poor cardiovascular health and posing a major risk of early death.
However, research published in the journal Heart has revealed that swapping regular salt for a substitute, in which a portion of the sodium chloride is replaced with potassium chloride, reduces these health risks.
The study compiled results from 21 clinical trials, involving nearly 32,000 participants, published up to the end of August 2021 and reporting the effects of salt substitutes on blood pressure.
The team found that salt substitutes reduced blood pressure in all participants, regardless of region, age, sex, weight and blood pressure-related factors.
“Salt substitutes produce consistent blood pressure-lowering effects across geographies and diverse participant subsets,” the researchers write.
No adverse effects were detected from the increased intake of potassium chloride. The effect of potassium chloride added to salt substitutes has, however, raised concerns for people with kidney disease, who should limit dietary potassium intake.
When the researchers carried out a smaller analysis of just over 24,000 participants, they found that switching to salt substitutes reduced the risk of heart attack, stroke and early death from any cause by 11%. The risk of cardiovascular disease was reduced by 13%.
Similar results were published in a study last year, involving over 20,000 participants with high blood pressure from 600 villages in China. It was unclear, however, whether the benefits from salt substitutes would be the same in other parts of the world.

“These findings are unlikely to reflect the play of chance and support the adoption of salt substitutes in clinical practice and public health policy as a strategy to reduce dietary sodium intake, increase dietary potassium intake, lower blood pressure and prevent major cardiovascular events,” the researchers write of the new study.
More than 14 million people in the UK have high blood pressure, about 5 million of whom are undiagnosed, according to the British Heart Foundation (BHF). High blood pressure contributes to around half of all heart attacks and strokes in the UK.
Tracy Parker, a heart health dietitian at the BHF, said: “This research is a helpful reminder to cut the amount of salt we have in our diets and to look for alternatives.”
But Parker cautioned: “While low salt substitutes have less sodium than regular salt, they still contain potassium which may not be suitable for some people with a heart problem and other existing health conditions. If you want to look after your health, it’s better to just eat less salt. Using different herbs and spices when cooking is a great way to add flavour and replace salt.”
Adding Salt to Food at Table Can Take Years Off Your Life, Study Shows
- A new study found that adding salt to prepared food can lead to premature death.
- Researchers suggest that you may be consuming more sodium in your diet than you think, and that adding salt to your food could increase your likelihood for premature death.
- On the other hand, the study shows that adding potassium to your diet could counteract the dangerous effects of salt.
The next time you find yourself at the dinner table, you might want to think twice before reaching for the salt shaker.
A new study found that adding salt to a meal after it was already prepared decreased life expectancy in women by 1.5 years and by 2.28 years in men. The study, published in the European Heart Journal, looked at UK Biobank data from 501, 379 participants who completed a questionnaire on the frequency of adding salt to foods on average. Researchers also collected urine samples to further examine the effects sodium has on the body.
Ultimately, the findings suggest that adding salt to prepared foods more frequently is associated with early death (higher hazard of all-cause premature mortality and lower life expectancy).
We’ve known for a while that reducing salt intake can be beneficial for heart health—studies have shown time and again that increased levels of sodium intake beyond a certain point increasingly become worse for the body in a number of ways, including cardiovascular disease risk. Rigved V. Tadwalkar, M.D., a cardiologist from Pacific Heart Institute, explains why this study, in particular, shows that adding extra salt to our food is not the best idea.
“What this study has done that’s interesting is that they’ve looked at the addition of salt in conjunction with preexisting salt that is already accompanied with the foods people are usually eating,” says Dr. Tadwalkar.
Because the study looked at the addition of salt to meals, and not the salt that’s already in prepared foods, it paints a clearer picture in showing that an increase in salt beyond what is already in our food is detrimental to our health. But, before you toss your table salt out for good, researchers did find that high intakes of potassium-rich foods, like vegetables and fruits, may reduce the effects of adding salt to foods and the consequences it may have on mortality.
“In a lot of ways, dietary potassium counteracts the effects of sodium,” says Dr. Tadwalkar. There are a lot of great potassium-rich foods that can curtail the disease or mortality risks that are associated with sodium. Fruits and vegetables make up most of them, but specifically bananas, potatoes, zucchini, pumpkin, leafy greens, broccoli, lentils, beans, and fish all are great sources of potassium that can thwart the effects of sodium on your heart health.
Who should specifically take a look at their sodium intake?
“Most people should look out for their heart health, regardless of their baseline condition,” says Dr. Tadwalkar. “There’s basically a sodium epidemic in this country, along with most western diets, so very few people are immune to the effects of sodium. This is partially the reason why there is a known epidemic of cardiovascular disease, because we have many hidden sources of sodium in foods where we might not think there’s much sodium but there’s actually more because of the packaging and the preparation” he adds.
Those with prior history of heart disease and those who have risk factors for heart disease, such as high blood pressure, high cholesterol, and diabetes, these are individuals that need to be even more conscious of their sodium intake, beyond the general population. Those with a family history of cardiovascular issues should be extra careful as well.
Bread, pizza, poultry, salad dressing, and canned and frozen meals are just a few common examples of foods that are high in sodium that you may not realize. According to Dr. Tadwalkar, “It turns out that a lot of health foods end up having a lot of sodium too, in an attempt to make the food more palatable.”
So the next time you head to the grocery store, take another look at the sodium content before you buy. And try skimping on the salt when it actually comes time to season your meal.
