Here’s a healthier way to prepare your broccoli

Published

on

Broccoli is known to be particularly beneficial to health thanks to its high sulforaphane content. Sulforaphane is a natural substance recognized for its antioxidant and anti-inflammatory activity. Preliminary studies have also shown that this compound may play a role in blood sugar control and help in the fight against cancer.

With all the benefits that broccoli brings to the body, scientists a few years ago developed broccoli pills that can be used as a dietary supplement. A 2011 study, however, found that eating whole broccoli provided more sulforaphane than taking the pill.

A team of Chinese researchers conducted experiments to find the best way to prepare broccoli to obtain the maximum sulforaphane.

Certain cooking methods should be avoided

In broccoli, there are compounds called glucosinolates and an enzyme called myrosinase. The latter is used by plants to defend themselves against herbivores. This is also called “myrosinase activity” which transforms glucosinolates into sulforaphane. To trigger myrosinase activity, broccoli must be damaged.

The problem with common cooking methods such as boiling or microwave cooking is that they significantly reduce the amount of glucosinolates in the vegetable. Even if cooking takes only a few minutes, the fact that myrosinase and glucosinolates are very sensitive to heat means that very little sulforaphane is obtained.

So, normally, eating raw broccoli would still be the best way to get a high amount of sulforaphane.

Sauté the broccoli for a tastier result

In China, people usually prepare vegetables by sautéing them. The researchers then tried this method on broccoli to see the stability of sulforaphane during the process.

The team used a bunch of broccoli to test the effectiveness of the method. First, they cut the vegetable into small pieces of about 2 millimeters to trigger myrosinase activity.

The researchers then divided the broccoli pieces into three groups. The first sample was left raw while the second was sautéed for four minutes, immediately after being chopped. As for the last sample, the scientists first let it sit for 90 minutes before blowing it up for four minutes.

The results showed that broccoli that was immediately sautéed contained 2.8 times less sulforaphane than broccoli that was allowed to sit.

ʺ Our results suggest that after cutting the broccoli florets into small pieces, they should be left for about 90 minutes before cooking. ʺ, the team concluded. They added that a 30-minute break could also work, although they haven’t tested it.

So, if you want to enjoy all the benefits of broccoli, you can try this technique, provided you are not in a hurry.

Engineers came up with a way to increase the cooling

US engineers have come up with a new way to cool semiconductor products, which does not involve the use of a thermal interface. Conformal coating in laboratory conditions has demonstrated its high efficiency in comparison with traditional methods of heat removal.

Engineers came up with a way to increase the cooling efficiency of processors by 700%

Electronic devices heat up during operation, and the greater the power, the stronger the heating, all other things being equal. This problem is especially acute with the miniaturization of devices. Researchers at the University of Illinois at Urbana-Champaign have come up with a new efficient way to remove heat from semiconductor products.

Usually, a radiator is connected to the hottest places of the microcircuit through a thermal interface. For example, thermal paste. Instead, American scientists proposed to cover the entire device with a thin layer of polymer insulator, and “fill” it with a layer of copper on top, completely repeating the shape of the device. This conformal coating is in close contact with the device and effectively removes heat from it.

“We compared our coatings to standard heat dissipation methods. It turned out that our method dissipates 740% more power per unit volume.one of the researchers explained.

It is expected that in the future this invention will make electronic devices, including telephones and computers, more powerful and compact.

US military space intelligence to spend billions of dollars buying

The US National Space Reconnaissance Office announced the largest ever contracts worth “billions of dollars” for the purchase of satellite imagery from commercial companies. There are three such companies – BlackSky, Maxar and Planet.

“These contracts, which are valued in the billions of dollars and will run for the next 10 years, represent a historic expansion of commercial imagery purchases by the National Space Intelligence Agency.”the agency said in a statement.

The exact amount of contracts is not called. It is noted that they are concluded for five years with the possibility of an additional extension until 2032.

Huge cheap smartphone with a giant battery Tecno Pova 3

Tecno introduced the Pova 3 smartphone, which boasts a huge battery and a huge screen.

The novelty received a 6.9-inch 90-Hz IPS display with Full HD + resolution. The battery capacity is 7000 mAh. Samsung has stopped experimenting with such smartphones, so it is very, very difficult to find something like this on the market.

The heart of the novelty is the SoC MediaTek Helio G88. There are 4 or 6 GB of RAM and 64 or 128 GB of flash memory. The main camera is represented primarily by a 50-megapixel main sensor, and the other two can be left out, as these are just “plugs” with a resolution of 2 megapixels. The resolution of the front camera is 8 megapixels.

From the rest, we can note stereo speakers, a design diluted with a vertical stripe, 25-watt charging and 10-watt reverse charging. By the way, for some reason, a 33-watt charger comes with the device, so this value appears in some promotional materials, which is confusing.

In the Philippines, where the smartphone first debuted, it costs just $172.

Netflix hid nine NFTs in its Love Death Robots

The third season of Love, Death & Robots premiered on Netflix last Friday. The service prepared a surprise and placed QR codes in different places and episodes that allow you to “mint” NFTs.

Netflix hid nine NFTs in its Love, Death + Robots series

Minting, also often referred to as minting, is the process of creating a non-fungible token and “registering” it on the blockchain. Usually, in order to “mint” NFT, you need to pay a network fee. After that, information about the non-fungible token and its author will be included in the blockchain.

The most popular NFT minting network is Ethereum. In February 2022, the amount of non-fungible ETH tokens used for minting reached a maximum.

The action is calledHunting 101“. The point is that the organizers hid 9 different NFTs in the form of QR codes. And the task of the viewer is to find them.

NFTs can be found both in the digital world of the series and in the real world: for example, on billboards and billboards.

When the user has found and scanned the QR code, it is necessary to mint the token through a smart contract. Or the second option is to simply download the JPEG image to your device.

According to the show’s official OpenSea account, viewers have only found three NFTs so far.

The number of tokens is not limited. This means that any user can find the same QR code and mint the NFT. The company does not charge for this. But in order to transfer NFT to your Metamask wallet, you need to pay for gas on the Ethereum network.

Further, the user can keep the tokens for himself for the collection, or resell on OpenSea. Now the average price of an NFT from Netflix is ​​0.0031 ETH (about $30).
