Israeli researchers have developed bacteria fed only with carbon dioxide, the Weizmann Institute of Science (WIS) in central Israel reported on Wednesday.

These bacteria, which build the entire biomass of their body from the carbon in the air, may help to develop future technologies to reduce greenhouse gas accumulation in the atmosphere and in the fight against global warming, the Xinhua news agency reported.

According to the study, published in the journal Cell, these bacteria were completely weaned off sugar, after a nearly decade-long process.

The Israeli scientists have been able to “reprogram” E.coli bacteria, which consume sugars and release carbon dioxide, so they use carbon dioxide from the environment and produce the sugars they need to build their body.

The researchers mapped the genes that are essential to this process and added some of them to the bacteria genome in their lab.

In addition, they have inserted the bacteria a gene that allows them to receive energy from a substance called formate.

This was not enough to make the bacteria change their diet, and “laboratory evolution” processes were needed to gradually wean them off sugar.

At each stage of the process, the cultured bacteria received a diminishing amount of sugar, and at the same time gained an abundance of carbon dioxide and formate.

The bacteria’s offspring were gradually weaned off sugar dependence, until after about six months of adjusting to the new diet regime, some underwent the complete nutritional turnover.

The researchers believe that the “healthy” habits of these bacteria may prove to be mostly healthy for earth.

For example, biotech companies that use yeast or bacterial cell cultures to produce commodity chemicals may be able produce these in cells using carbon dioxide instead of large amounts of corn syrup used today. (IANS)

Intermittent Fasting Benefits Those at Risk for Diabetes: Study

Time-restricted eating benefits those at risk for diabetes

Researchers have found that people who are at high risk of developing diabetes improved their health when they consumed all of their meals over a span of just 10 hours, or less over a period of 12 weeks.

The study published in the journal cell Metabolism, reported a form of intermittent fasting, called time-restricted eating, improved the health of study participants who had been diagnosed with metabolic syndrome.

Metabolic syndrome is the name for a group of risk factors, such as high blood pressure and cholesterol levels, that increase the risk for adverse health issues, from heart disease and diabetes to stroke.

The researchers from University of California in US, found that when participants restricted their eating to 10 hours or less over a period of 12 weeks, they lost weight, reduced abdominal fat, lowered blood pressure and cholesterol and enjoyed more stable blood sugar and insulin levels.

“Time-restricted eating is a simple dietary intervention to incorporate, and we found that participants were able to keep the eating schedule,” said study co-author Satchin Panda from the University of California in US.

“Eating and drinking everything (except water) during a 10-hour window allows your body to rest and restore for 14 hours at night. Your body can also anticipate when you will eat, so it can prepare the body to optimize metabolism,” Panda added.

Time-restricted eating (eating all calories within a consistent 10-hour window) allows individuals to eat in a manner that supports their circadian rhythms and their health.

Circadian rhythms are the 24-hour cycles of biological processes that affect nearly every cell in the body.

Erratic eating patterns can disrupt this system and induce symptoms of metabolic syndrome, including increased abdominal fat and abnormal cholesterol or triglycerides.

The study involved 19 participants diagnosed with metabolic syndrome, with 16 taking at least one medication, like a statin.

Participants used an app created by Panda called myCircadianClock to log when and what they ate during an initial two-week baseline period followed by three months of 10-hour time-restricted eating per day.

They were told they could decide what time to eat and how much to eat as long as all food consumption occurred within a 10-hour window.

At the end of the 12 weeks, participants averaged a three per cent reduction in weight and body mass index (BMI) and a four per cent reduction in abdominal/visceral fat.

Many also experienced reductions in cholesterol and blood pressure and improvements in fasting glucose. Seventy percent of participants reported an increase in sleep satisfaction or in the amount they slept.
