Four foods that become toxic when stored in the refrigerator

Although the refrigerator keeps food fresh, some foods should not be stored in the refrigerator because they can become toxic. Doctor Dimple Yangda, who is a specialist in gut health, stated on Instagram that these foods are garlic, onion, ginger and rice and revealed the reasons why this is so. Garlic Garlic can become soft if stored in the refrigerator. "Never store garlic in the refrigerator because it starts to mold very quickly, and mold on garlic is actually linked to cancer," Yangda said, advising to store garlic in a dry, dark place. "Garlic has a low acidity, which makes it prone to the deposition of the bacterium Clostridium botulinum, which is one of the culprits of botulism," she warned. Onion Onion is a crop that is resistant to low temperatures. The expert explains: "When you put onions in the fridge, the starch starts to turn into sugar and mold starts to form." Many people make this mistake. Cut the head of the onion, use half...

Electric heating

Electric heating uses relatively inexpensive tools to directly convert electrical energy into heat energy with a conversion efficiency of roughly 100%. Applications that are frequently used include industrial processes, cooking, water heating, and space heating. An electrical appliance that transforms an electric current into heat is called an electric heater. Every electric heater contains a heating element that is an electrical resistor and operates on the principle of Joule heating. When an electric current flows through a resistor, the electrical energy is transformed into heat energy. The active element in most contemporary electric heaters is nichrome wire; the heating element shown on the right is nichrome wire supported by ceramic insulators.

As an alternative, a heat pump, which uses electricity exclusively to transfer the thermal energy from the environment, primarily air, can achieve a heating efficiency of about 300%, or 3.0 Coefficient of Performance. The refrigeration cycle of the heat pump is powered by an electric motor, which pulls heat energy from the earth, outside air, or even the inside of a refrigerator, and transfers it to the area that needs to be warmed (in case of a fridge, the kitchen). This uses electricity considerably more efficiently than direct electric heating, but it also necessitates pipes and much more expensive equipment. For air conditioning, certain heating systems can be turned backwards, cooling the interior while venting much hotter air or water outside or into the earth.

Artificial intelligence: Google's new model 'will outperform humans in solving intelligence tests'

Google has launched a new artificial intelligence (AI) model that it claims will "answer questions more carefully" because its "functionalities are more advanced". AI content generators sometimes invent things that developers call hallucinations.  The new Gemini model has been tested to solve problems in 57 areas, including mathematics and the humanities. "This is the new era of artificial intelligence," said Sundar Pichai, head of Google.  Earlier this year, Google launched its own version of the chatbot – Bard – calling it an "experiment".  During the presentation, the program made an error when answering the space question.  Google claims that the new model is "the most capable" and will outperform humans in solving intelligence tests.  Gemini can recognize image, text and sound, but it is not a product in itself.  It is a program that will be integrated into existing Google tools, including search, but also into the Bard...

Trojan apps that take photos of users without permission, if you have them, delete them

  ESET antivirus experts have released a new list of Android messaging apps that track users and steal their information. These are apps from the Google Play Store and almost all of them look like regular messaging apps. However, behind the scenes they run a remote device access Trojan known as "VajraSpy" and are part of the "Patchwork APT" campaign, with the primary goal of spying on downloaders. These apps can steal your contacts, files, call history and messages, and some can even access your WhatsApp or Signal conversations, record phone calls or see what notifications you receive, the website PhoneArena" published post. The worst that has been discovered is that they can take pictures of users and record sound in the environment. They are primarily used in Pakistan and India, but it is possible to find them in other areas as well. If you accidentally came across them, skip them, and if you downloaded them, delete them. These are the Google Play Store apps ...

The leaves of this evergreen plant will solve your health problems

  Spring is in February and we often hear someone coughing or sneezing, not to mention a stuffy nose. Teas, rest, honey, it's usually what we usually resort to first, but it's not always that effective.
