Scientists told what the food of the future will look like

Scientists told what the food of the future will look like 86

Danish scientists suggest that in the future, meat will be replaced by more healthy and environmentally friendly seafood – algae, shellfish and tiny fish. The research results are published in the journal Frontiers in Psychology.

Beef farming does not fit well with the concept of sustainable development adopted in Western countries. At the same time, not all people are ready to give up meat in order to preserve the climate.

Researchers from the University of Copenhagen studied consumer behavior in food choices and made a prediction of how it can be influenced and how to replace meat in the European food basket.

It is known that meat products have a special meat flavor, which the Japanese call umami. This taste is created by monosodium glutamate, and the human tongue has special L-glutamate receptors that pick it up. Product manufacturers make good use of this – monosodium glutamate is included in food additives of the E600 – E699 group.

At the same time, umami is present in the taste of some plant foods – walnuts, broccoli, tomatoes, shiitake mushrooms.

“A lot of people just crave the taste of their minds,” the study leader, Professor Ole G. Mouritsen of the Department of Food Science and Consumer Behavior, quoted a press release from the University of Copenhagen. a small amount of animal products such as meat, eggs and milk, along with vegetables. However, alternatives to juicy steak could be considered, of which there are many.”

The authors suggest looking for alternative sources of protein and healthy fatty acids among seafood, especially those with huge renewable reserves, but still not fully exploited. The researchers estimate that only sprat can meet 20 percent of Denmark ‘s protein needs.

“And sprat fishing will help avoid the over-exploitation of more well-known fish species such as cod, flounder and salmon,” explains the professor.

In addition to the sprat, there are many small benthic species of fish – gerbils, gobi, which can serve as a source of protein, as well as seaweed and cephalopods.

Scientists note that today, out of ten thousand types of algae, only 500 are used as food, despite the fact that they are incredibly rich in beneficial nutrients and vitamins. The picture is the same for cephalopods – about 30 out of 800 species are used for food in the world.

“It has a lot to do with our culture and traditions,” says Mouritsen. “It takes time to change our eating habits. We’ve eaten and cooked meat for over a million years. So while seaweed, squid and shellfish contain important fatty acids and vitamins and taste great, we are still reluctant to classify these species as food sources.”

The authors believe food technology, which has long used the two main flavors, sweet and meat, in food flavorings, will help make seafood more attractive.

“Sweetness signals the brain for calories and survival, while umami signals that we are consuming something good for the muscles. However, many seafood, seaweed and vegetables have their own great taste,” the scientist notes.

In particular, according to researchers, many vegetables develop a sweet and umami flavor during fermentation – this can be used to develop a rational diet for the future.

Polar vortex: “wild” winter is coming in the US, Northern Europe and East Asia after the 16th of January

Polar vortex: "wild" winter is coming in the US, Northern Europe and East Asia after the 16th of January 87

In the upper atmosphere above the North Pole, experts saw a rapidly swirling vortex of cold air that could bring severe frosts to the United States, Northern Europe and East Asia. Serious cold snap and snowy weather are expected after January the 16th.

Snowfalls and a cold snap hit South Korea since the start of 2021, hitting historic snow maximums and temperatures. In the country, for the first time since 1964, television and newer communications are sending people cold snap warnings:

The situation is similar in Japan, where a new snow storm hit historic highs:

On January 7, the thermometer In Beijing dropped to -20 degrees Celsius, breaking the 1966 record. In other regions of China, the temperature is also not sugar, and you can only move around in special uniforms:

The cold even reached Taiwan, where the temperature in some areas dropped below freezing point, snow poured down and people realized that rice terraces can be used as a ski jump:

Even more snow went to Spain, where on January 6, 2021, a temperature of -34.1 ° C was recorded – the lowest on record. After that, a snow storm hit the country, which has not been seen for 80 years:

The same thing happens in Canada and in the northern states of the United States:

It seems that after a stratospheric warming, the subpolar vortex began to split:

The vortex itself is a standard phenomenon. However, this time experts were surprised at his movement. It is possible that in the near future it will be divided into two parts. 

Scientists associate the strange behavior with the changed climate in the Arctic, which has become warmer. From September to December, the amount of ice cover decreased significantly.

The polar vortex is a low-pressure region located in the stratosphere and filled with cold air. When the jet stream of air that holds the vortex weakens, the low pressure area moves south. 

As the ice shrinks, more moisture will move inland. It will turn to snow, so snowfalls are expected. Snow, in turn, reflects heat, leading to a cold snap.

Hospital in Naples was evacuated after a new, huge sinkhole appeared

Hospital in Naples was evacuated after a new, huge sinkhole appeared 88

Eyewitnesses said they heard a loud crash at dawn when a huge hole in the ground formed outside the Ponticelli Ospedale del Mare hospital in eastern Naples.

Early in the morning of January 8, 2021, a sinkhole occurred in the parking lot of a clinic in Naples. The depth of the formed cavity is about 20 meters, the total area of ​​the hole is about 2,000 square meters.

No casualties were found at the scene; firefighters say the sinkhole “affected an area of ​​about 500 square meters” and engulfed several cars parked near the hospital.

As the press writes and as a little can be seen from the videos, rescuers and firefighters were running around the pit together with the governor of the area.  But who should be there in the forefront are Italian geologists, since Naples stands in the very center of the volcanic system known as the Phlegrean Fields.

If the surface collapsed, moreover – the surface reinforced with concrete and reinforced from below with some kind of communications, then we are talking about serious soil deformations caused by the activity of magma.

Italy has been in doubt since the summer of 2020, because swarms were observed there in very atypical places in May, and according to the forecasts of old Italian seismologists, who had witnessed many strong earthquakes, it should have boomed in the August region.

Fortunately, nothing bad happened to Italy and there was no big earthquake. But, since there are swarms, it means that something is being prepared, the magma is gathering strength. 

Following this particular sinkhole event – an obvious sign that a major earthquake in Italy is already very close.

A new great pandemic cycle has begun (again) in China

A new great pandemic cycle has begun (again) in China 89

In the first months of 2020, the whole world with a certain fright followed the events unfolding in China, where people fell on the streets during the day and astronauts wandered, and in the evening crematoria began to smoke. And now, with the onset of December, the cycle seems to be repeating itself.

Shunyi area in Beijing, where the authorities announced “wartime status” the day before. As you can see in the videos, thousands of people are lined up in the queue for mandatory testing:

Dalian city, where “wartime” is also declared. Neighborhoods are blockaded, people are walled up in entrances, familiar characters of George Lucas roam the streets:

Chinese ‘rescuers’, before performing a combat mission:

Chengdu City:

Daluo Port, Yunnan – tourists came for adventure and they received the ‘time of their life’ after leaving the ramp:

If something happens in Beijing, it does not mean that tomorrow the same will happen everywhere. However, the trend towards such dynamics is observed and, as the practice of the first wave of the pandemic has shown, all countries and people, to one degree or another, have taken into account the ‘Chinese experience’. 

Therefore, one must think that everything will now be in peace, as in spring – a new global round of the fight against the Covid has begun in China, a new great pandemic cycle!
