Study: blue light from screens shortens life – tested on flies

A new study has emerged that confirms the harmful effects of blue light from screens. Moreover, the negative effects may increase with aging. According to scientists from the University of Oregon, this effect was manifested in fruit flies, fruit flies.

Study: blue light from screens shortens life - tested on flies

The researchers exposed them to harmful radiation at the age of 2 days, then successively at the age of 20, 40, 60 days. As it turned out, the harmful effects of blue light are enhanced in older flies and shorten their lives. This fact confirmed the previous study, which said that long-term exposure to blue light affects the lifespan of flies.

It is important that the light does not have to fall into the eyes. At the same time, we note that many operating systems and monitors already have built-in blue light filters to reduce its harmful effects. Indeed, as studies have shown, the radiation of the blue part of the spectrum negatively affects vision, knocks down biological rhythms and destroys melatonin, a hormone that regulates the process of falling asleep and waking up.

Therefore, doctors continue to talk about the need to stop reading social networks before bed. At the same time, it was previously reported that blue light is useful.

Take fire on yourself the creators spoke about the capabilities

The Surrogat-V underwater drone, codenamed Vedomoy, presented at the Army 2022 forum, can imitate a submarine, distract the enemy, and also take fire on itself.

An important function of the “Surrogate” is the imitation of a covered boat. By depicting its hydroacoustic “portrait” with the help of onboard means, the drone will be able to lead the enemy on a false trail or cause fire on itself. It is very difficult to get into it because of its small size and good maneuverability.

Representative of the Central Design Bureau “Rubin”.

Like the first Surrogate, the drone can imitate a submarine in exercises, testing new detection systems and anti-submarine weapons. The drone is equipped with sonar countermeasures, which allows you to play very complex tactical episodes.

The “Surrogate” drone was presented along with a mock-up of the prospective strategic nuclear submarine “Arktur”. In the aft part of the submarine there are two lockable compartments intended for Surrogates. Drones can also act as “sentinels”, patrolling the waters around the submarine on combat duty.

The developers also drew the attention of journalists to the camouflage of blue triangles on the top of the drone, which should reduce the visibility of the device for anti-submarine aircraft and drones.

Recall that the displacement of the drone is 40 tons, and the range reaches 1500 km.

For HIMARS and M270 missiles with a range of 500

In Europe, a new JFS-M missile is being developed, which will be capable of hitting targets at a distance of 500 km. The missile can be launched using the M270 and HIMARS systems.

The length of the rocket is 2.6 m, it belongs to the cruise class: after launch, it expands the wing with a span of 1.5 m. With a launch weight of 250-300 kg, the rocket is capable of speeds up to 1,000 km/h. One HIMARS cassette holds two JFS-M missiles.

In the air, the missile travels at low altitudes, making it invisible to air defense systems. With the help of the JFS-M rocket, you can destroy “standard infrastructure”. It is not suitable for the destruction of “heavily armored bunkers”.

The missile’s flight path is adjustable. The operator of the complex can change it after start-up.

The US is also developing a missile for HIMARS, the PrSM (precision strike missile) or precision strike missile, which can have a range of up to 650 km.

In general, four models are expected in the series: Mate 50e, Mate 50, Mate 50 Pro and Mate 50 RS. They will receive curved screens from local (Chinese) manufacturers and the recently introduced HarmonyOS 3.0. The younger model is credited with SoC Snapdragon 778G, all the rest – Snapdragon 8 Gen 1 without 5G support. However, some sources also talk about the use of Snapdragon 888 (also in the version with an LTE modem), so not everything is clear here yet.
