Artificial intelligence to combat antibiotic-resistant bacteria

Published

on

Although it generates skepticism in some sectors, the use of AI in medicine breaks new ground in the area, by allowing large volumes of data to be analyzed quickly, contributing to decision-making after combining new information with patterns detected by these systems, under a look that usually escapes human analysis, at least in the first instance.

A medical problem that has not yet been fully resolved is the existence of bacteria resistant to antibiotics. Currently, in the absence of a concrete solution, there are people who die in hospitals after contracting an infectious condition of this kind.

An AI solution to combat antibiotic resistance

Resources already exist to combat antibiotic-resistant bacteria, but the task of finding which antibiotics are still effective against a particular pathogen often takes two or more days. This delay is due to the fact that the samples are grown in laboratories and the drug tests are carried out in Petri dishes, to evaluate their effectiveness. The problem is that, in addition to being an expensive process, many critically ill patients cannot wait more than two days.

Scientists from the ETH Zurich University, from Switzerland, trained AI algorithms on the mass spectrometry data, to teach them to detect antibiotic resistance on their own. This mechanism should offer very fast results, since the scientists point out that in this way it is possible to detect signs of resistance to antibiotics in bacteria up to 24 hours earlier than current diagnostic tools. By detecting these signs early, doctors can design antibiotic therapy more precisely and start treatment sooner.

To train this AI system, the scientists used a dataset of more than 300,000 mass spectra of individual bacteria. The resulting database covers around 800 different bacteria and more than 40 different antibiotics, for which the algorithm was able to detect antibiotic resistance autonomously.

What is most important about this approach is that algorithms can answer these questions very quickly, which clears the way for rapid and tailored antibiotic therapies, especially in severe cases of infection.

In the near future, the ETH Zürich University team plans to launch a clinical trial, to assess how an AI-based approach would work under real-life conditions, as the research has so far only been carried out in a laboratory.

Ricoh Theta X Camera Announced

Published

on

Ricoh spoke about the Theta X camera, which is scheduled for release in March 2022. This is the first panoramic camera with a 2.25-inch touch screen, replaceable battery and micro-SD card slot.

Unlike previous Ricoh Theta cameras that relied heavily on a smartphone or tablet to manage, share and edit footage, Theta X takes a more versatile approach. This is facilitated by the presence of a color touch screen, which is used both for navigating through the camera’s menus and for composing shots. While this screen is much smaller than mobile device displays, it allows you to get things done on the go without worrying about pairing Theta X with your smartphone or tablet.

The replaceable battery and memory card slot mean that if you have extra batteries and cards, you can shoot for as long as you want without having to recharge your device. Previous Theta models had only built-in batteries and flash memory, which greatly limited their capabilities.

Among the less significant improvements, the following can be noted: the need to enter the SSID when connecting a smartphone or tablet via Bluetooth has been eliminated.

The Theta X features new 48MP CMOS image sensors, an upgraded processor and an improved lens. When shooting photos with a 360° field of view, Theta X allows you to shoot at a resolution of 60 megapixels. In terms of video, Theta X shoots 5.7K (5760 x 2880 pixels) video at up to 30 fps with “improved image stabilization”. Other features include a GPS receiver and a USB-C port for charging without having to change batteries.

The Ricoh Theta X is expected to go on sale in March 2022 for $799. In addition to the camera, the kit will include a USB cable, a soft case and a battery.

G.Skill and Asus set the world memory overclocking record: DDR5-8888, CL88

Published

on

G.Skill International Enterprise, which specializes, among other things, in the production of high-performance memory, announced that, together with Asus, it has achieved a world record for overclocking DDR5 memory. DDR5 modules were overclocked to an effective frequency of 8888 MHz with delays of CL88-88-88-88.

Video of the day: Tesla Model S Plaid vs. Lucid Air in high-speed races

Published

The source published a video report of the fight between two high-speed electric vehicles: Lucid Air and Tesla Model S Plaid. The cars competed in high-speed races on a quarter-mile stretch, classic for this discipline. A total of four attempts were made.

None of the participants managed to come first in all four races. But still, the superiority was on the side of the Model S Plaid – this car won three of the four races, including one with a smooth start. This was predictable because it has a claimed 0-60 sprint time of 1.99 seconds compared to the competitor’s 2.5 seconds. Although Tesla is inferior in terms of power of the power plant (1020 hp vs. 1111 hp), the smaller curb weight (2190 kg vs. about 2270 kg) contributes to more acceleration.

However, Lucid Air’s results also look convincing. This electric car managed to win the race when the Model S Plaid was not in quick start mode. In addition, the Air can be tuned for more straightaway acceleration, Lucid says, but the manufacturer now focuses more on “luxury and efficiency” than speed.
