Modern ships are distinguished from their "ancestors" by their extreme strength and reliability. But sometimes one big hole is enough for even an advanced ship to sink. Scientists from the University of Rochester have created a unique material that can significantly increase the survivability of water transport.
The basis of the development lay superhydrophobic coating - a special water-repellent composition. Having processed two metal surfaces with this material, scientists connected them together so that the coating was turned outward with two sides.
As a result of processing, the metal disk used to test the technology turned out to be almost unsinkable. Researchers made several large holes in it, which were supposed to simulate holes on a real ship, but even when immersed in water, an experimental sample floated to the surface.
According to scientists, a similar technology can be used in combination with any metal. In the future, a new type of material will improve the survivability of ships and increase the safety of their passengers.

Blue light from our phones and computers can negatively affect a person’s life expectancy.
The prolonged exposure to blue light coming from our phones, computers, and many other household appliances can negatively affect a person’s life expectancy. Scientists suggest that the blue waves that emit LEDs damage the cells of the brain and retina, even if there is no direct incidence of light rays. Scientists conducted a series of studies on an ordinary fruit fly, as a result of which it turned out that the light waves released during the burning of LEDs accelerate the aging process.
Is blue light harmful?
Light is electromagnetic radiation, each color of which has its own specific amount of energy. At the beginning of the light spectrum there is red, which has low energy and is easily perceived by the human eye, closer to the top of the spectrum is blue light, which has the highest energy and is able to penetrate the retina, quickly wearying our organs of vision.
Artificial blue light, which comes from modern gadgets and devices, occupies the most “harmful” part of the spectrum, the wavelength of which is between 380 and 500 nm. Light waves of this range are the shortest of visible radiation, while scattering most actively.
Scientists have long confirmed the negative effects of blue light on humans, but still continue to conduct more detailed studies on its effects on the human body and still do not plan to dwell on the information received. So, scientists from a university in Oregon published the results of new research in the journal Aging and Mechanisms of Disease.
During the experiment, researchers used an ordinary fruit fly - Drosophila melanogaster, whose organism, due to its cellular development mechanisms, is similar to other animals and people.
During the study, researchers used 3 groups of flies. The first group underwent daily 12-hour cycles: 12 hours in the light and 12 hours in the dark. The second group was always in the dark and was used as a control, and the third group was subjected to filtered blue light. According to the results of the study, it was found that the flies from the first group had a shorter life span. A study of flies that were exposed to 12 hours of blue light confirmed damage to retinal cells and even brain neurons, reducing the ability of flies to climb fences.
In the experiment, mutants of fruit flies were also used, some of which did not have developed organs of vision, but even brainless flies showed brain damage and impaired coordination. Thus, flies did not have to see the light in order for it to cause disturbances in the body. Researchers also noted an interesting fact that flies try to avoid blue light if given a choice.
Scientists note that the presence of natural light is crucial for the circadian rhythm of the body - a cycle in which a number of physiological processes occur, such as brain activity, hormone secretion, cell regeneration, etc. However, the increased exposure to artificial light, which is increasing in the modern world, is one of the risk factors for sleep failure and many other circadian disorders.
The use of LED lighting, various gadgets and devices exposes people to more and more light in the blue spectrum. But due to the fact that these technologies are quite new, it is not possible to find out about their impact on a person throughout his life.

Google has added support for two languages in the News aggregator application instead of one. So the company wants to reach 60% of the global audience that speaks and reads in two or more languages.
This is stated on the Google blog, reports BusinessCensor with reference to TJournal.
After updating the News application, users can add a second language to the settings and switch between news in different languages. As planned by the company, this will help people who have just moved to another country and want to read news from their homeland, as well as those who live in territories where they speak several languages.
In the new version, users can also read news in different languages at the same time - notes will be formed in a single feed. Google explained that the update will not affect personalization settings, and news in another language will correspond to the interests of users.
So far, bilingual support has appeared only in the mobile version. In the desktop version, the service still allows you to select only one language. The new feature has earned for users from 141 countries and supports 41 languages on iOS and Android. Source:

The other day it became known about the purchase by Google of the manufacturer of wearable devices Fitbit. In the light of events, the corporation hastened to patent the acquired developments, and one of the first was named - “Low-profile capsule for fitness monitoring”. The technical component of the device is hidden, but some details can be distinguished from the provided drawings.
Previously, Fitbit's core business was fitness equipment, so it’s logical to continue the production line of the acquired company. The product has the shape of a smart watch, where you can see the places under the bracelet straps.
Fitbit-Google - patent for a new device-3
On the front side there will be a square-shaped display, most likely with touchscreen support. On the back, a sensor module is indicated, a similar one is used to read the user's medical parameters.
By the way, the application was submitted by previous Fitbit owners back in May of this year, and the actual registration occurred six months later. One can only assume that $ 2.1 billion paid for Fitbit will be an economic success for Google.
