Scientists create a virus “capable” of destroying any kind of cancer

An Australian company called Imugene has created a virus that can eliminate all types of cancer. So far it has been tested on Petrie plates and mice, where it worked by reducing tumors and killing diseased cells. Human tests should start soon.

Although it seems strange that a virus is used to treat a disease, this is possible and scientists have been doing it for years. A modified herpes virus has been implemented to treat some types of skin cancer.

Now, scientists are using cowpox virus as the basis for their cancer treatment, called CF33. The first tests on mice have reduced tumor cells, so Imugene believes that the next logical step is to perform experiments on humans, in order to verify the effectiveness of the treatment.

During the next tests, which will take place next year in Australia and other countries, the treatment will be implemented in some types of specific cancers, such as triple negative breast cancer, melanoma, lung cancer, bladder cancer, gastric cancer and intestinal.

Professor Yuman Fong, a cancer treatment specialist, told the Daily Telegraph that there is evidence that some viruses could fight cancer since the early 1900s when people were vaccinated against rabies and their cancer disappeared. entered the reference phase.

However, it was feared that just as the virus was toxic to cancer, it was also to humans, but now things are different and could be the best way to attack cancerous tumors.

In Imugene experiments, patients will observe that the virus will be injected directly into their tumors, where it will multiply to the point of destroying it. The immune system itself should therefore be alerted to other cancer cells in the body, attacking and eliminating them.

This is very promising, but it will take years before the health strategy is used in hospitals, because it remains to be seen how the immune system reacts to the virus itself. Furthermore, cancer cells mutate to survive, and this is how they have become resistant to treatments such as chemotherapy and immunotherapy.

Remedies for obesity can stop the spread of cancer

Cancer is the second leading cause of death in the world after cardiovascular disease. Sometimes doctors manage to remove the primary tumors and people have the hope of a full recovery. However, if the tumor has so-called metastases and it begins to spread, the chances of a complete cure are greatly reduced. However, scientists from Belgium have been trying to find more than one year looking for a way to stop the complications of cancer, and in a recent study found that the disease spreads using human fat as an energy source. So what is it that can be done to stop the development of cancer using anti-obesity drugs?

Perhaps scientists are one step closer to creating a cure for cancer

The results of the scientific work carried out by Belgian scientists were published in the journal Nature communications. A team of scientists led by Olivier Feron continued his previous study and found that cancer cells accumulate fat in tiny vesicles, which were called lipid drops. Fats are used as an energy source, so it is logical that the cells saturated with them spread much faster than others.

How does fat contribute to cancer?

According to scientists, TGF-beta2 protein, also known as transforming growth factor beta, is responsible for the accumulation of fats in cells and the aggressive behavior of cells. It is a kind of switch that, on the one hand, allows cancer cells to accumulate energy, and on the other hand, forces them to use the received power for distribution.

Thanks to the new discovery, scientists were able to develop a new plan to slow the development of cancer. In theory, to stop the occurrence of metastases, researchers need to develop a tool to block the production of TGF-beta2 protein. It would also be nice if the future medicine slowed down the formation of fats and their transportation throughout the body. Just before that, they need to make sure that the TGF-beta2 protein is not involved in other processes important for human life. Also, people taking the medicine, which is essentially a remedy for obesity, will have to adhere to a certain diet.

Fat is a source of energy for cancer cells.

It is possible that in the world there are already drugs suitable for these purposes. It is important for scientists only to study their composition and experimentally check whether they are really able to slow down the development of cancer. Typically, such tests are first performed on laboratory mice. For example, in 2018, scientists introduced a tiny human brain into the body of a rat and looked, what came of it.

In general, cancer can be defeated by turning cancer cells into fat cells. According to the scientific journal Cancer cell In 2019, Swiss scientists led by Professor Gerhard Cristofori were also able to prevent cancer complications in this way. By the way, they conducted an experiment on mice with aggressive breast cancer. This cancer is often found in women, so the discovery can be considered very important for the scientific community.

By 2024 GM And Michelin Will Bring Airless Tires To Passenger Cars

By Mayukh Saha / Truth Theory

Michelin and GM had unveiled a novel wheel technology- Uptis (Unique Puncture-proof Tire System) in the year 2019. The airless tires are in the preliminary stage currently, but there is a chance of them being rolled out by 2024.

The vice-president of General Motors said that the company is excited to see what all Uptis can do. He also said that the collaboration with Michelin is thrilling.

The rubber tires currently used are prone to dangers like blowouts but the airless tires will eliminate such problems. They will also be low-maintenance as people won’t need to check them for punctures and pressure.

Another big advantage of this high-technology is that the number of tires that are wasted will decrease. Also, the amount of raw material used to make rubber tires will go down along with the energy required to build those tires. It will be beneficial as far as sustainability is concerned, believe the creators.

Uptis tires will also be more durable because they won’t undergo damage easily. Unlike the rubber tires that get damaged by the excess or lack of air, these airless tires will have no such issues.

The CEO of Michelin, Menegaux said that Uptis supports the company’s dream of making mobility sustainable. According to him, working with GM, the company can conquer the future now.

Michelin’s VISION Concept Tire is a 4 pillar strategy to conduct R&D and bring sustainability in mobility. Uptis is the first step first in this direction.

The intention with which GM is working is to introduce the airless tires in passenger vehicles by 2024. However, the details about Uptis aren’t been out yet. Neither of the companies is willing to share the details about this wheel technology.

It’s not clear what material is used to make these tires. It’s also unknown how they’ll function. Any noticeable difference has also not been mentioned.

Michelin said in its FAQs that Uptis has a common concept as that of their Tweel technology. The latter is a tire-wheel assembly where ‘spokes’ are to bear the weight and there is an outer rim.

General Motors was expecting to start testing the airless tires on the Chevrolet Bolt EVs by the end of 2019, but there are no further developments in this area.

Scientists have created the first camera capable of capturing “the invisible”

American scientists have perfected the fastest camera in the world in order to capture transparent objects and invisible processes such as shock waves or laser pulses. The description is given in the journal Science Advances. The Caltech scientific team has manufactured a camera that literally captures the invisible, at a billion frames per second

Scientists continue to push the limits of what cameras are capable of.

As a newly developed ultrafast photography device (pCUP), it is capable of capturing an impressive billion frames per second.

That’s amazing, but it’s not a record, because some of the same researchers developed a camera that can take 10 billion shots per second in 2018.

However, this new camera also has another party trick: it can capture transparent objects and other invisible phenomena with the naked eye, such as shock waves.

While this incredible technology will not be very useful for your holiday photos or Instagram selfies, it promises to have a variety of scientific uses in physics, biology and chemistry.

The camera works using the innovative technique used in the 2018 model, where measurements of light intensity are combined with a static image and some advanced mathematics to produce all those frames.

New this time is an additional ingredient, phase contrast microscopy: this is an older photographic technique in which changes in the relative positions of light waves as they pass through different densities become changes in the bright.

“What we have done is to adapt standard phase contrast microscopy to provide very fast images.”

“This allows us to obtain images of ultrafast phenomena in transparent materials,” says electrical engineer Lihong Wang of the California Institute of Technology (Caltech).

Phase contrast microscopy was invented by Dutch physicist Frits Zernike in the 1930s, and clings to the way light changes speed as it passes through the materials.

These changes in speed make materials such as glass much easier to detect with this technique.

As for the newest part of the technology, the Caltech team calls it ultrafast compressed lossless coding technology (LLE-CUP).

This marks the next generation of Streak cameras, devices that capture an entire event at once in a way that allows the time of light waves to be recorded.

Wang’s previous work added a new component, a load-coupled device, which reduced the times.

Now, he has combined an improved form of this configuration with microscopy that filters out the scattered light to map the changes that the human eye cannot see.

With increasingly sophisticated scientific cameras, they are leading to new discoveries about the world around us, whether to take snapshots of the human body or to record quantum entanglements.

Here, the researchers successfully captured the movement of a shock wave through water and a laser pulse through a crystalline material.

According to the researchers, their camera could be used for more purposes in the future, as it can be combined with several other existing optical imaging systems.

It could, for example, eventually allow scientists to capture the way flames expand in combustion chambers, or record the signals that travel through neurons on a microscopic scale.

“As the signals travel through the neurons, there is a tiny dilation of the nerve fibers that we hope to see,” says Wang.

“If we have a network of neurons, maybe we can see their communication in real time,” he concluded.
