Researchers discovered a way to “chase” the HIV virus and make it vulnerable

HIV infection is no longer a death sentence today - so far, however, the AIDS pathogen cannot be removed from the body of infected people, but only suppressed effectively. 
But now there is new hope in the development of a definitive cure: Researchers may have discovered a way to "chase" the virus out of its hiding places in the body and thus make it vulnerable.

The sufferers are emaciated: The immune deficiency disease AIDS spread like a nightmare in the 80s and 90s. But then modern medicine could finally end the mass death - the so-called antiretroviral therapy proved to be a great blessing for those infected with HIV: Daily medication suppresses the development of virus particles in the body and thereby protects against the onset of an immune deficiency. Those affected can lead a normal and healthy life through the treatment and do not pass the infection on sexually.

Unfortunately, despite the treatment, the infection remains chronic: therapy cannot completely drive the viru…

Scientists look for the origin of Wuhan's coronavirus in animals

Most experts rule out that they can be snakes and point to mammals.

WHO decides not to declare the international emergency due to the Wuhan coronavirus.While the World Health Organization (WHO) decides whether to declare the Wuhan coronavirus outbreak an international emergency, after it has claimed 17 victims so far, Chinese authorities have decreed quarantine in three cities and asked 20 million citizens not to leave their cities except for "special reasons" in an attempt to contain the virus.

Other security measures have also been implemented, such as the closure of public transport and controls at airports.
The source of the infection is suspected to be a food market in Wuhan, a mega-city of 11 million people located in central China. 
The market was closed on 1 January and disinfection measures were implemented, making it difficult to trace the origin of the infection, i.e. which animal caused the infection. 
Dead and live animals, wild and domestic, including marmots, bi…

WWF notes that the Tokyo 2020 Olympics "are far" from being sustainable

The environmental NGO WWF said Monday that the organization of the Tokyo 2020 Olympic Games "raises serious doubts" about the sustainability of the sporting event, due to its standards for using natural resources such as wood, fishery products or palm oil.

The organizers of the next Olympics have placed respect for the environment among their top priorities for the Olympic event, and in January 2016 they established a code for the sustainable use of resources and services.

However, WWF believes that Tokyo 2020 is “far away” from reaching its goal of getting the next Olympics to be “at the forefront of sustainability,” according to the environmental organization in a letter sent to the International Olympic Committee and published Monday. .

The protocols established for the use of raw materials such as wood, paper, fishery products or palm oil are “far below the best existing practices worldwide and are inappropriate for a global event like the Olympic Games,” he says. in the no…

Scientists introduced a device that creates holograms using ultrasound & polystyrene ball

Researchers at the University of Sussex in the UK have introduced technology that can create holograms using ultrasound and a 2mm polystyrene ball. They can move and interact with the observer.

Scientists called the new technology "multimodal acoustic trap display" (multimodal acoustic trap display, or MATD). Images are created between two horizontal plates on which many tiny ultrasound speakers are mounted. They create an inaudible sound field in which there is a "pocket" of low pressure, where a polystyrene ball enters. By moving the "pocket", you can move the ball, forming an image. Colors are added to the image using the projector.
Through careful monitoring of the ultrasound field, scientists can add sound effects and music to animated images. Vibrations can be adjusted to receive sound waves in the entire range of human hearing and, for example, to imitate clear speech. In addition, you can interact with images and even feel them in your own hands.


Researchers used an AI algorithm to analyze social interactions of monkeys

An artificial intelligent program that recognizes and follows chimpanzees can make it easier to study the animals in the wild.

Computer scientist  Arsha Nagrani from Oxford University and her colleagues have created artificially intelligent face recognition software that can identify individual chimpanzees on video recordings. As a result, it takes less time and resources to follow animals in their natural habitat and thus study their behavior.
Even in low lightThe Nagrani team trained their algorithm with fifty hours of archive footage of chimpanzees made in southeastern Guinea. 

The video material of 23 monkeys, ranging from newborn to 57 years old, yielded 10 million images of their faces. Based on this, the algorithm 'learned' to recognize and track individual animals.

The algorithm also functioned well in low light and when the recordings were of poor quality. Images on which the chimpanzees did not look directly into the camera were no problem either. 

In 92 percent of the ca…

Do indoor plants purify the air? Science says no

A study states that air improvement is an exaggeration and that it would take up to 1,000 plants per square metre for its effect to be felt. 

That plants are an excellent decorative element is something no one doubts. However, many give these indoor gardens the power to regenerate the air. But does this ability have a real basis? 
According to a new study by researchers at the University of Drexel, in reality this is simply an exaggeration, as opening a window would be much more useful for cleaning the room than having one of these pot plants.
"This has been a common mistake for some time. Plants are great, but they don't really clean the air in a room fast enough to have an effect on air quality in a home or office." 
Explains Michael Waring, lead author of the article published in the Journal of Exposure Science and Environmental Epidemiology and professor of architectural and environmental engineering at the Drexel School of Engineering.

Researchers have grown the first ever lungs in mouse embryos

Methods used on mice are planned to be used for growing an organ in the body of the animal for further transplantation in humans. 
This will solve the main problem of today's transplantology - the need to wait for donor organs.Growing organs from stem cells on synthetic scaffolds is not easy, a new lung growth strategy to grow an organ in the body of an still developing animal.
There are millions of people with incurable lung diseases who are dying from a shortage of donor organs for transplantation. 

A group of scientists from the United States and Japan have grown fully functional lungs in mouse embryos, opening up new opportunities for organ transplants in human patients. The research was published on the Columbia University website.

Considering the difficulties of other groups of scientists growing organs from stem cells on synthetic frames, the researchers have defined a new strategy for organ growth.

They suggested that it might be much easier to raise a new organ in a still deve…
