Animals have previously been successfully printed organs using a 3D printer. Northwestern University researchers inserted prosthetic ovaries in sterilized mice, and the animals produced healthy offspring. Rhesus monkeys have been implanted with blood vessels made from the same animals’ material at the Chinese business Sichuan Revotek.

Different bioprinting technologies are being developed by research organizations or companies: 

Frame. The inorganic proliferation of living cells, which vanishes with the formation of natural connections between cells. The key challenge is finding a material that is equally flexible or stiff as the organ to be replaced. It must decay fast in order to avoid interfering with the extracellular matrix’s strength and dissolve without leaving hazardous substances behind. Wireframe printing is possible using hydrogel, titanium, gelatin, synthetic, and biopolymers. 

Frameless. Ready-made cells are applied to a hydrogel foundation. The cells are chilled and housed in thin hydrogel spheroids while they are in the printer. The temperature rises to 36.6°C during printing, the spheroids scatter, and the cells build their own natural framework – the cellular matrix. This type of printing is less prevalent than wireframe printing since it was developed later and is more difficult to duplicate. 

Mimicry. Future technologies will allow for the simultaneous production of entire organ replicas. Bioprinting at the molecular level is being developed for it, as are in-depth studies of cell nature. 

3D bioprinting has progressed from an idea to a viable commercial product. Bioprinting firms’ principal clientele to date have been huge pharmaceutical enterprises. Drug testing is sped up by testing drugs directly on printed human tissues. 

Although expensive bioprinters will not be available in city clinics for another five years, 3D printing is already helping some patients heal. Osteomyelitis infected the jaw of an 83-year-old Belgian lady. The repair was more costly and took longer than removing the sick jaw and replacing it with a printed replacement. The procedure was conducted by a team of doctors led by Professor Jules Poukan, and the woman was able to communicate shortly thereafter.

With the advancement of bioprinting, it will be easier to remove a damaged limb and generate a new one than it will be to treat ailments that are currently treated without amputation. Bioprinting is appealing to cosmetologists and plastic surgeons, in addition to doctors. The desire to stay youthful and attractive, rather than the treatment of uncommon and complicated diseases, will drive the adoption of 3D printing of human organs. Perhaps, in the future, individuals will be able to replace their organs and looks as simply as they change their cellphones.

A reality TV star who sells her farts in small jars has decided to stop selling, even though she made $1,000 for a jar. But her fans don’t have to worry about it. Because now she’s going to sell her fart in the form of non-fungible tokens, better known as NFTs.

Stephanie Matto, who starred in the reality TV show The 90-Day Groom and has become very popular on TikTok, says that she was recently hospitalized with stomach complications because she was eating so much high-fiber food that she was producing more and more farts.

She calls himself a fartrepreneur, began farting in jars and selling them online in November and documented on TikTok the foods she ate to reduce flatulence, such as beans, protein muffins, and eggs. Matto was reportedly making about $50,000 a week from his very lucrative business, but the strain soon became too much.

But although Matto has moved away from the actual fart jar business, she still participates in the NFT world, where she sells cartoon images of her fart jars. Non-fungible tokens are most often associated with jpeg images, but they are essentially a decentralized receipt on a blockchain that can be any hyperlink.

Matto’s new website claims that 100 of the virtual fart jars will be redeemable for real-world fart jars, so it doesn’t seem like Matto is completely giving up the fart game just yet. Another 70 tokens will be redeemable for used panties and 30 of the fart jar tokens will be redeemable for some of Matto’s used lingerie

The fart-based businesswoman is also offering Zoom meetings and even mentorship for anyone who wants to create a business like hers.

Whatever you may think of selling farts in a jar, Matto seems financially alright. And it looks a little bit funny to see how NFTs can be monetized on the internet right now. What a time to be alive.

Humans unfortunately don’t have the ability to regrow naturally or artificially one of our body parts. Instead, we use prosthetic legs or arms to fill the missing body part. This isn’t ideal but it’s the best way to restore our abilities. Most animals are similar to us with the exception of salamanders, starfish, crabs, and lizards which have the capability of filling the regeneration of at least some limbs.

Lately, scientists at Tufts University and Harvard’s Wyss Institute published a study that showed a frog with a missing limb being treated with a five-drug cocktail using a wearable bioreactor in the stump. After the 24-hour exposure to the drug, it took 18 months for the frog to restore its limb nearly fully. This was the first of its kind successful procedure which led to a significant milestone in medicine and surgery. The next big step is to test the drug on mammals and with a little hope of success, one day a similar drug can be implemented on humans.

In my opinion, the journey to imposing this drug on humans is still very long. By the time more experiments are done and tests on a larger variety of animals will be conducted, a new technology might be introduced. The early stage of the five-drug cocktail might be a false hope for currently disabled humans that had a body part amputated.

Most of us indeed were in a situation when we were delighted with a level of service in a restaurant, bar, etc. Then wanted to reciprocate for such a pleasurable treatment. We got the bill, and suddenly we realized that we had no cash on us. At this point, many of us probably resigned to leave a tip being simultaneously a lit bit confused. We wanted to reward somebody for being kind to us, but on the other hand, we didn’t have the opportunity to do that conveniently. You can admit that it isn’t a pleasing feeling.

And now…. you do not have to feel like that anymore. At this moment, a new app called TipTip goes on the stage! The main aim of this application is to make giving a tip as straightforward as possible. So let’s go through the usage of it. In the beginning, anyone, who wants to be given a financial bonus for their service, has to download the app from AppStore or Google Play. Next, they have to set up their account by submitting necessary data and agreeing on the bylaw of TipTp. And that’s it. In the next few days, they should receive their business card with a unique QR code. Ever since, whenever they serve a customer, they can share this business card with the client and hope that their service has deserved a reward.

On the part of a client, there is even less fuss. You simply have to scan the QR code on the business card or use an NFC reader on your phone. Then you can choose an amount that you want to tip, and the whole process is finished. You don’t have to have the app even to take advantage of its boon.

Besides the ease of its use, the app has several other benefits. It has a very intuitive and helpful interface that displays how much money you receive on a particular day. The transactions are secured because they are processed by a well-known company called tPay. And finally, the time of waiting for your money is equaled only to one day! That’s great.

According to the information delivered by the company, whose name is TipTip, too, the app currently has 336 satisfied users that so far carried out 9027. The average amount of tip that is left equals 14,66 zł. I would have supposed that the amount was about 5 zł, so it surprised me how generous we can be. The enterprise is currently available only in Poland when recently granted the status of the small payment institution.

The app hit the right note at the time of the pandemic and the process of gradually giving up on cash. It bodes a promising future and great chances for further development. But the times are very unpredictable, so we cannot be sure what will be the fate of TipTip.

Recent slumping prices follow continued reports of surging inflation, a disappointing December jobs report and the release of minutes from the Federal Reserve Board’s December meeting, which signaled a winding down of measures to prop up what it described as a steadily improving economy. There was also a massive sell-off of Bitcoin futures, CoinDesk reported.

After nearly hitting $52,000 on Dec. 27, Bitcoin has ranged between $33,000 and $50,000 in the days since.

Despite the recent slump, Bitcoin started 2022 on a relative high note, with a strong November and early December that gave way to the recent downward trend. After starting 2021 in the $30,000 range, Bitcoin increased throughout the year and hit its current all-time high when it went over $68,000 on Nov. 10.

The volatility and stalling price continues apace with new economic uncertainty over the Omicron COVID-19 variant, new statements from Federal Reserve Chairman Jerome Powell on the health of the economy, and ongoing comments from U.S. officials like SEC Chairman Gary Gensler on cryptocurrency regulation.

Despite falling back significantly from its latest all-time high price, many experts still expect Bitcoin’s price to rise above $100,000 at some point — describing it as a matter of when, not if. Shortly after Bitcoin’s latest all-time high, Ethereum marked its own new all-time high when its price went over $4,850. Ethereum, too, has seen similar volatility following the latest high.

What’s Behind the Latest Bitcoin Drop? 

Many investors see Bitcoin’s price swings as part of the game, but “volatility is tough for individual investors to deal with,” Noble says. Like Yang, he warns against selling too fast.

Recent price fluctuation has followed new uncertainty over the country’s lingering fight with COVID-19, new regulatroy acctions by the U.S. government, as well as the new legislation pertaining to crypto in the infrastructure bill. In an industry as new and unproven as cryptocurrency, it doesn’t take much to drive big swings in price. More generally, new short-term investors who are selling their holdings in reaction to the latest drop may be contributing to the drop in Bitcoin’s value, according to the report of glossnade insides, a blockchain analysis firm.

While fluctuations are expected, Noble says he’s been surprised if by drops earlier this year. “I thought the market was maturing and these things would be less frequent and severe. Boy was I wrong,” he says. 

Some of this year’s drops have been caused by a combination of factors, Noble theorizes, from excitement about low-quality coins, to negative remarks from Elon Musk, to China recent cracked all investors in BTC.This mix of factors has potential to make sell-offs “all the more violent,” says Noble. 

He likens the drop to the stock market crash of 1987, from which the markets took months to recover. But because crypto moves a lot faster today than equities did in the 1980s, Noble says we may see a quicker recovery. 

“Don’t panic and puke,” Noble says. “If you keep your positions small, you can try to tolerate the volatility.”

Of course, solar panels is very useful nowadays, some country spend thousands of euros for impoving this way of receiving the energy.

The biggest solar farm is located in China in the desert.

Tengger Desert Solar Park was the biggest one in 2018

It is located in Zhongwei, Nixia, China. It covers an area of 43 km². In 2018, it was the solar park with the largest peak power capacity (1,547 mw).

Nowadays, when almost everyone has access to the Internet, we are looking for new solutions to make our lives easier. Due to the fast information flow and our busy lifestyle, we have less and less time for basic life activities, including shopping groceries or preparing food. Fortunately, in this matter, we have many options and with just a few clicks we can easily solve the problem of an empty fridge or lack of food.

1.Grocery shopping delivery is more and more often practiced by people, for several important reasons: firstly, it does not require leaving the house, secondly: we can choose the exact time of delivery, and thirdly, often (but not always) the variety of products is greater than in a nearby supermarket.

Unfortunately, there are also disadvantages of such kind of shopping, e.g. a delivery fee is often charged, we still have to spend a lot of time choosing products and usually we have to spend a certain amount of money (we will not make small purchases)

Examples of companies offering such services are: Frisco, Barbora, Carrefour, Auchan

2.Another thing that makes life easier in terms of our daily nutrition is, of course, ordering ready meals directly in a given restaurant or through applications – this method is often more convenient for the customer because we don’t have to wait for connection to the restaurant and can pay very quickly. The biggest advantage of this solution is the large selection and fast delivery.

Unfortunately, hardly anyone is able to afford to orderevery meal in a restaurant, rather people choose such a solution once in a while, when they do not have time to organize and prepare a meal.

Examples of applications offering food orders are: Uber Eats, Bolt Food, Pyszne.pl, Deliveroo

3. For especially busy people, there is one more option, which has recently become very popular with people – the box diet. Catering companies offer delivery of meals for a full-day, with a choice of caloric value of the meal, type of diet and delivery time, as well as in an extended version the possibility of choosing meals for a given day. Although this option is not very cheap, it certainly pays off more than eating out every day or ordering food.

Many catering companies (eg Maczfit) offer their clients an application in which they can manage their diet, change their diet type at any time, or change the delivery address for a given day. This is a good option when we do not have time to cook or re not able to plan a diet and control calories consumption.

Companies offering a box diet: Maczfit, Nice to Fit You, BeDiet Catering(by Ewa Chodakowska, Catering fitness

While speaking with investors, Apple CEO Tim Cook revealed that the number of active Apple devices in the world has reached 1.8 billion units. In 2021, their number increased by 150 million.

Active Apple devices include iPhone, iPod touch, iPad, Mac, Apple Watch, and Apple TV.

In January last year, the company reported 1.65 billion devices, and a year earlier – about 1.5 billion. In 2016, Cook reported that the number of iPhones in the world exceeded the one billion mark.

Devices are rated as active by being connected to Apple services within the last 90 days.

Along with this, the company reported record sales in the first quarter of 2022, which includes the New Year holidays. Apple received $123.9 billion in revenue for a profit of $2.1 per share. Analysts predicted – $ 118.66 billion / $ 1.89. The company also announced a record profit of $34.6 billion.

What amazes me the most is that they achieved record sales with the chip shortage that was recently announced. Of course, 1.8 billion devices is an unfathomable number. And Apple plans only to increase it. Well, let’s see if they can do it.
