The United States will develop “rules of conduct in space”

The US administration is working to prepare rules for the use of outer space that will strengthen “America’s sources of strength.” This was stated by US Vice President Kamala Harris, speaking at a meeting of the US National Space Council.

The United States will develop

At present, there are few rules that would allow safe, efficient and sustainable activities in outer space. Therefore, in consultation with representatives of the civil sector, including commercial companies, our administration is currently developing the first set of rules for new types of space activities.“, – she said.

These rules will encourage innovation and ensure competition. They will strengthen the sources of America’s global strength, namely the ability to innovate and manufacturing capabilities. These rules will be flexible enough to cover activities in space that are still hard to imagine. They will also help ensure that our country remains a global model for the responsible use of space.Harris continued.

Nobel Prize in Chemistry awarded to three scientists for development

The 2022 Nobel Prize in Chemistry has been awarded to a group of scientists – the Americans Caroline Bertozzi and Barry Sharpless, as well as the Dane Morten Meldal. This was announced on Wednesday by the Nobel Committee of the Royal Academy of Sciences.

Scientists became laureates for “the development of click chemistry and bioorthogonal chemistry,” the committee’s reasoning statement says. As the secretary of the Nobel Committee announced, in this way the researchers contributed to the functional way of building molecules.

This year’s Chemistry Prize was awarded not for something super complicated, but for work on something that, on the contrary, is easy and simple. Functional molecules can even be created directly”, commented Johan Okvist, Chairman of the Nobel Committee for Chemistry.

This is the second Nobel Prize for Sharpless. In 2001, he already became its laureate together with William Knowles (USA) and Ryoji Noiori (Japan) for the discovery of catalysts for the production of so-called mirror molecules necessary for pharmaceuticals. This time, Sharpless took the first step by coming up with the concept of click chemistry, which is a form of simple and robust chemistry where reactions occur quickly and avoid unwanted by-products.

Soon, he and Meldal, individually, introduced what is now considered the crown jewel of click chemistry—copper-catalyzed azide-alkyne cycloaddition, an efficient chemical reaction that is in widespread use today. It is used in pharmaceuticals, for DNA mapping and the creation of materials adapted for specific purposes.

Bertozzi took click chemistry to the next level by developing click reactions within living organisms to map important but elusive biomolecules on the surface of cells called glycans. Its bioorthogonal reactions proceed without disturbing the normal chemistry of the cell. All over the world, these reactions are used to study cells and monitor biological processes. With their help, scientists have been able to increase the targeting of anti-cancer drugs that are currently undergoing clinical trials.

500 fps in Overwatch 2 at 1440p and Ultra settings

A few hours before the release of Overwatch 2, Nvidia published an infographic in which they presented performance data for various current models of their video cards in the game. Of course, all the attention here is on the new GeForce RTX 40 (Ada Lovelace) models.

According to Nvidia official data, the GeForce RTX 4090 is the only model that, at a resolution of 2560 x 1440 pixels and ultra settings, can provide frame rates in excess of 500 fps. The result is, of course, impressive. And it is even more impressive against the background of the GeForce RTX 4080, which is one step lower with 16 GB of memory – this model is capable of only 368 fps under the same conditions. However, both of these models are suitable for 360-Hz monitors.

The performance gaps between the GeForce RTX 4080 12GB, RTX 3080 and RTX 3070 are not that big anymore, but still noticeable.

Nvidia recommends using the GeForce RTX 3080 Ti when playing games at Full HD resolutions above 360Hz, while the GeForce RTX 3060 can be used with Full HD monitors that support 144Hz.

This model was previously leaked under the Vienna name, but promotional materials show that the name has been changed. In the brand line, the novelty will be one step higher than the T-Rex 2.

At the moment, we can definitely talk about more than 150 sports modes, a dual-band GPS module, 4 GB of flash memory, a heart rate sensor with a pulse oximeter function, and an autonomy of up to 14 days.

As for the early data, the watch was credited with a titanium case, sapphire crystal, a 1.28-inch AMOLED screen with a resolution of 416 x 416 pixels and a peak brightness of 1000 cd / m2, as well as water protection (20 ATM). The announcement of new items is expected on October 13.
