Cell phones carried close to the body: ANSES calls for caution

Cell phones

A major study by the National Health Security Agency concluded that contact with or moving a mobile phone 5 mm from the luggage has no health impact. But she advises caution and asks manufacturers to update their phones to reduce SAR.

Is a phone worn near your body harmful to your health in terms of exposure to electromagnetic waves? In this regard, the United States National Health and Safety Administration (ANSES) advises manufacturers to be cautious and take action by publishing reports on human exposure to cell phones that are close to the body.

“Before 2016, manufacturers had the right to measure the SAR of their smartphones at a distance of 0 to 25 mm from the head or body. Therefore, the specific absorption rate may be higher than the authorized 2 W when contacted or at 5 mm / kg is much higher. Some products can even reach 7 W / kg, provided they do not violate the regulations, because their SAR is 2 W / kg, such as 15 mm “, explained to the evaluation agency head 01net.com ANSE Physical risk.

Some devices have been deleted or updated

“Considering the development of models and uses, the exposure control of mobile phone radiation was modified in 2016. Since then, manufacturers have been asked to assess the exposure under real-life conditions, that is, when the phone is placed very close to the body, The longest distance is 5 mm, “Anses explained in a press release. .

Olivier Merckel said: “Since 2016, due to the European directive RED, because of the high SAR, certain models of phones have also been withdrawn from the market or updated.” This is the case with Orange Hapi 30, Honor 8 or Wiko Tommy 2.

Biological effects, but not health

Therefore, when the phone is very close to the body, such as in the inner pocket of a jacket or jeans, ANFR requires ANSE to identify possible biological effects. To this end, the Agency has analysed its own publications and all the latest studies on the possible effects of this level of exposure. ANSES must apply data from the scientific literature to humans, which are primarily related to animal or cell culture.

Avoid carrying your phone with you

The results of expert assessments indicate that SAR in excess of 2 W / kg has a biological effect on brain activity. Olivier Merckel clarified: “However, it has no effect on health because it does not exceed the body’s ability to adapt.” “For prevention, for reference, we recommend reducing exposure. You can use exempt The carrying case holds the phone in your hand or in a bag. The manufacturer can also perform some Software Updates on the Model. ”

In addition, ANSES explained in its conclusion: “The IAEA proposes to change the regulatory requirements in order to perform” DAS relay “mobile phone compliance verification measures for mobile phones.


Google launches free version of Stadia and gives you two months trial of video games


Google’s cloud gaming service is open to all French internet users who are confined with a nice gift: two months of Stadia Pro free for any subscription to the service. What to look after during confinement, since nine video games, including excellent titles, are available free of charge.

This may be the real start for Stadia, Google’s cloud gaming service. A few months after the chaotic launch of its paid offer, the web giant has just announced the launch of the free version, an exit released a few weeks earlier to entertain confined gamers.

Starting at 6 p.m. this Wednesday, April 8, and gradually over the next 48 hours, Stadia will be accessible to all owners of a Gmail address. And it’s a pretty good plan, because Google is offering two months of Stadia Pro to everyone, which includes access to a selection of games.

Just go to Stadia.com to register. Of course, you will need to enter your credit card number in order to take advantage of the service, but your account will only be debited at the end of the two-month period if you wish to keep Stadia Pro. It’s easy to cancel the subscription with a few clicks from the settings.

A cool selection of nine free games

Stadia Pro, normally billed at 9.99 euros per month, includes free access to a selection of video games, which evolve each month. From this evening, you will therefore be able to enjoy the games listed below for free for two months. A varied selection, ranging from FPS “AAA” (Destiny) to motor racing (GRID) via some undesirable pearls (the excellent SteamWorld Dig 2), or the ideal party game for a local multiplayer game session (Spitlings). This list should logically be completed next month with other free titles, which will be announced in the coming weeks.

Free games for two months

  • Destiny 2: The Collection
  • GRID
  • Gylt
  • SteamWorld Dig 2
  • SteamWorld Quest: Hand of Gilgamech
  • Serious Sam Collection
  • Spitlings
  • Stacks on Stacks (On Stacks)
  • Thumper

Your account will also allow you to purchase games on the platform. All the titles you have acquired will remain accessible to you even if you decide to stop the “Pro” subscription after two months. But beware, games are often more expensive on Stadia than the competition…

Other important information: if you have already paid for Stadia and then canceled your subscription, you can take advantage of this offer again, open to everyone. Current Stadia Pro subscribers will not be billed for two months.

No 4K yet

Please note, this two-month free Stadia Pro lacks an important function: game streaming is limited to 1080p and sixty frames per second … and not 4K, as the subscription provides. Google explains that it took this decision to avoid cluttering the network, which is particularly stressed during this period of confinement.

Remember that you can use Stadia on your PC or Mac via Chrome and on one of the compatible Android mobiles. To play, just connect a controller (those of the PS4, Xbox 360 or One will do the trick, but more exotic models too) or a mouse / keyboard pair in Bluetooth or USB to your computer or mobile. It is also possible to play on your TV via a Chromecast Ultra … with a big downside: the only controller compatible in this configuration is the Stadia Controller, which you probably do not have.

Never mind: if the streaming video game tempts you, or if you dream of immersing yourself in one of the games offered, do not hesitate to try the experience.

These researchers have developed a powerful and simple to produce Lithium-Sulfur battery

Lithium-Sulfur battery researchers

The new battery provides 5 days of battery life for smartphones and allows them to travel 1,000 kilometers in electric cars without the need for a charging case.

Researchers at Monash University in Australia have just developed a lithium-sulfur (Li-S) battery, which is hailed as the most efficient battery in the world. It does power the smartphone for five days and guarantees 1,000 kilometers of electric cars.

Easy to produce high capacity battery

To achieve this feat, the researchers used the same materials that have been used in lithium-ion batteries, but modified the design of the sulfur cathode so that it can withstand higher loads without the cathode. Affects the overall capacity or performance of the battery.

Researchers and engineers used bridging technology from the 1970s to make laundry detergent. This approach seems to be the right solution, as the research team explained that it has achieved a level of stability never before seen in the field of energy storage.

The first prototypes of this new battery have been developed in Germany and are currently being tested in Australian electric vehicles and photovoltaic panels.
