New York: A study involving Indian-origin scientists revealed that damaged tomatoes unsuitable for sale can be used as a powerful source of generating electricity.
“We have found that spoiled and damaged tomatoes left over from harvest can be a particularly powerful source of energy when used in a biological or microbial electrochemical cell,” said Namita Shrestha from South Dakota School of Mines and Technology.
“The process also helps purify the tomato-contaminated solid waste and associated waste water,” added Shrestha, who is working on the project with Venkataramana Gadhamshetty, an assistant professor at South Dakota and Alex Fogg, an undergraduate chemistry major at Princeton University.
The research findings were presented at the 251st National Meeting and Exposition of the American Chemical Society held in California’s San Diego city on Wednesday.
“The project began a few years ago when Alex visited my lab in Fort Myers, Florida, and said he was interested in researching a local problem, especially local tomatoes grown in our state and the large waste treatment issue,” Gadhamshetty said.
Tomatoes are a key crop in Florida. The project is important to the state because Florida generates 396,000 tonnes of tomato waste every year, but lacks a good treatment process.
The team developed a microbial electrochemical cell that can exploit tomato waste to generate electric current.
“Microbial electrochemical cells use bacteria to break down and oxidise organic material in defective tomatoes,” Shrestha explained.
The oxidation process, triggered by the bacteria interacting with tomato waste, releases electrons that are captured in the fuel cell and become a source of electricity.
The power output from the team’s device is quite small — 10 mg of tomato waste can result in 0.3 watts of electricity. But the researchers note that with an expected scale up and more research, the electrical output could be increased by several orders of magnitude. (IANS)
California, October 17, 2017 : California Governor Jerry Brown has signed a state senate bill, allowing a gender-neutral marker on birth certificates and driver’s licenses starting from 2019.
California thus became the first state in the US to allow a “nonbinary” gender to be marked on birth certificates, Xinhua news agency reported.
The so-called “nonbinary” gender means not exclusively male or female or a combination of two or more “genders.”
According to the Gender Recognition Act approved on Sunday, California will offer a gender-neutral option on state documents for those who are transgender, intersex and others who are not identified as male or female.
The law, published on the government official website, also made it easier for people to change their gender identity on official documents.
“Existing law authorises a person who was born in this state and who has undergone clinically appropriate treatment for the purpose of gender transition to obtain a new birth certificate from the State Registrar,” the bill read.
The Golden State is now also the second state in the US to allow residents to be identified by a gender marker other than “F” or “M” on their driver’s license.
Oregon and the District of Columbia had earlier issued the gender-neutral option on their driver’s licenses.
Sep 21, 2017: Tomatoes are loaded with nutrition and oxidants that help to keep you salubrious and your wellbeing fit as a fiddle. The numerous health benefits of tomatoes can be credited to their abundance of nutrition values and vitamins, including vitamin A, vitamin C, and vitamin K, and vitamin B6, folate, and thiamin.

If you consume tomatoes daily, it tends to lift your lifestyle. You may find them in incalculable diverse sustenances, including pastas, pizzas, ketchup, different refreshments, and as an included flavor component in dishes from breakfast to supper.
Here are some interesting health benefits of tomatoes
Vitamin A in tomatoes enhances your vision and also forestall night-visual deficiency and macular degeneration.
Keeping up blood wellbeing
Tomato contains vitamin A, potassium, and iron that is fundamental for keeping up ordinary blood wellbeing.
Health benefits of tomatoes
Decreases danger of heart disease
The lycopene in tomatoes can secure you against cardiovascular diseases. Expending tomatoes frequently helps diminish the levels of cholesterol and triglyceride in the blood, lessening the deposition of fats in the veins.
Eating tomatoes on a regular basis can keep your digestion sound as it avoids constipation as well as and loose bowels.
Health benefits of tomatoes
Tomato reduces hypertension, ie the ‘high blood pressure’. This is due to the potassium found in tomatoes. Potassium reduces the tightness in blood vessels, thus enhances the flow and lowers the stress on the heart.
Tomatoes help in maintaining healthy bones, teeth, skin, and hair. Limited application of tomato juice can also cure severe sunburns. They are also dominant in fighting the skin aging.
Health benefits of tomatoes
Stops urinary tract infection
Tomato consumption also diminishes the frequency of urinary tract infections as they have relatively more water content that stimulates urination. It also eliminates toxins, salts, excess water, uric acid from the body.

Old Mosul has been completely shattered in the battle to recapture the city from Islamic State militants
About 900,000 people have been displaced by the battle for Mosul, and many neighborhoods have been completely destroyed by war
Areas around the village are slowly being re-populated, but many places are entirely without services like trash collection, electricity, and running water
Mosul, September 5, 2017 : “All you can hear at night is the sound of broken doors flapping in the wind,” says Abd Elaam, a 50-year-old furniture maker. “Even soldiers stay indoors after dark.”
Elaam is currently one of the very few civilians living in Old Mosul, an ancient neighborhood shattered by the battle to recapture the city from Islamic State militants. Like many families that survived IS rule, he says, his resources are completely exhausted by the war and he has nowhere else to go.
Other families trickle in by day, looking to repair their broken homes or recover the bodies of their dead loved ones. But even during daylight hours, the neighborhood is dangerous, riddled with bombs and an unknown number of militants hiding out in the vast network of tunnels under the tightly-packed buildings and piles of rubble. The level of destruction has been compared to World War II Dresden.
“A IS militant came out of one those houses two weeks ago,” Elaam says, gesturing towards another dusty, broken street. “He blew himself up near two families. They were all injured and the bomber was cut in half.”
The militant’s body, like other fallen IS fighters in Old Mosul, was shoved under the rubble to reduce the smell of rot in the 45 degree-plus weather. When Iraq declared victory over IS in early July, the bodies of dead militants lay scattered in buildings and on the streets of nearly every block. Authorities searched through giant piles of concrete, once homes, for the remains of civilian families. But, they said, the only government department responsible for the IS bodies was garbage collection.
Old Mosul is far from re-establishing city services like trash pickup. There is no running water, electricity or businesses open. Yet other families are following Elaam’s lead, and plan to return to their homes as soon as possible.
“In a few days I will move back and bring my family,” says Ghanem Younis, 72, resting on a beige plastic chair in a sliver of shade. “If they provide electricity and water, everyone would come back.”
Younger men and children squat around Ghanem, recalling the isolation of the final months of the battle that began late last year. “We couldn’t go more than 50 meters from our front doors,” says Sufian, a 27-year-old unemployed construction worker. “We spent our time sitting right here with Uncle Ghanem.”
But it is not sentiment driving some families home despite the dangers, adds Elaam, as more neighbors join the conversation.
“People cannot stay with friends and relatives forever,” he says. Camps for those displaced are also crowded. “No one has anywhere else to go,” he adds.
A few blocks away, outside the checkpoints that cut off the Old City, the Zanjelli neighborhood is slowly being repopulated.
Construction workers build a market to replace one destroyed in airstrikes, while the owners of what was once a shoe store paint the shelves, hoping to re-open in the coming weeks. The wreckage from a few of the destroyed homes has been cleared away, and the bodies of many of the dead are now buried in graveyards.
In less than five minutes of conversation, at least three people tell us about family members, including toddlers, killed in airstrikes in the last months of battle.
“There was an IS sniper firing from next to my house and the airstrike hit us,” says Youseff Hussain, 35. “Fifteen members of my family were killed.”
Rebuilding the neighborhood, adds Hussain, is made doubly frustrating by the fact that it was Iraq’s allies, including the United States, who destroyed many of their homes as they battled IS from the air.
Many locals say the sacrifice of property and lives may have been necessary to prevent the city, then under siege, from total starvation. But after bearing the brunt of the war with IS, largely considered a global threat, residents say they thought the international community or the government would help them rebuild.
The only aid families here get right now, Zanjelli residents say, is Iraqi military rations, as soldiers share their food.
“There is nothing they can do to pay us back for what we have lost,” says Hussain. “But shouldn’t we at least get refunded for our property?” (VOA)
