Fitbit recalls smartwatches with batteries that can overheat and burn the user : NPR

The health tracker firm Fitbit is recalling about 1.7 million smartwatches containing a lithium-ion battery that may overheat and burn the person.

The recall is for the Fitbit Ionic Smartwatch; not one of the firm’s different smartwatches or trackers are affected. Fitbit bought about 1 million Ionic Smartwatches within the U.S. and one other 693,000 internationally, in accordance with the Client Product Security Fee.

“The well being and security of Fitbit customers is our highest precedence. We’re taking this motion out of an abundance of warning for our customers,” the corporate stated in an announcement.

Clients are being urged to cease utilizing their Ionic Smartwatches and return them to Fitbit for a refund. The corporate can also be providing clients a reduction on different Fitbit merchandise.

The recall was issued Wednesday following a slew of reviews of the watch battery overheating, together with not less than 115 incidents within the U.S. and one other 59 internationally.

There have been 78 reviews of burn accidents within the U.S. – two involving third-degree burns and 4 involving second-degree burns – in addition to 40 burn accidents globally.

Fitbit stated it performed a “thorough investigation” and located that harmful overheating occurred in “very restricted cases.”

The smartwatches had been bought in shops comparable to Greatest Purchase, Kohl’s and Goal, in addition to on-line from September 2017 by December 2021. Fitbit stopped producing the Ionic in 2020.

Ionic Smartwatches have 3 buttons, a coloured LCD display screen, and the mannequin quantity FB503 on the again.

Swiss rivers on track to overheat by the end of the century — ScienceDaily

“Folks are likely to suppose that water is a limiteless useful resource in Switzerland,” says Adrien Michel, who lately accomplished his PhD in environmental science and engineering at EPFL. “However by the top of this century, we could effectively have to decide on between utilizing our rivers to water our crops and damming them up so as to produce electrical energy.” Michel carried out his doctoral work on the Laboratory of Cryospheric Sciences (CRYOS) inside EPFL’s College of Structure, Civil and Environmental Engineering. After finishing a retrospective research on the affect of worldwide warming on Swiss rivers, Michel has now revealed a forward-looking research on the identical matter within the journal Hydrology and Earth System Sciences.

Three eventualities

Michel’s analysis lays out three attainable eventualities that depend upon whether or not greenhouse fuel emissions are low, average or excessive. In essentially the most excessive state of affairs, through which we take no motion, river temperatures in the summertime could be anticipated to extend by 5.5°C in Alpine areas and by 4°C in Swiss Plateau catchments. On the similar time, common river discharge may lower by 30% within the mountains and 25% in lowland areas. Conversely, if CO2 emissions are decreased according to the Paris Local weather Accord, each Alpine and Swiss Plateau rivers would solely be 1°C hotter on the finish of the century, and discharge would lower by 5% in mountain catchments whereas remaining almost unchanged within the lowlands. Within the low-emission state of affairs, almost half of all remaining glaciers could be preserved, with retreat leveling off round 2050, whereas within the high-emission state of affairs they might all however disappear.

Pushing the extremes

The research additionally confirmed that winter and summer time extremes can be higher in Plateau areas underneath all three eventualities. Within the winter, elevated precipitation will result in greater discharge. In the summertime, extra sporadic precipitation together with greater evaporation charges attributable to rising temperatures will result in a lower in discharge. Michel relied on local weather projections from MeteoSwiss and glacier soften knowledge from ETH Zurich to mannequin snow and discharge ranges and river temperatures.

“We’ll absolutely be capable to develop oranges on this a part of the world,” says Michel. “However what about the remainder of biodiversity?” This research is of course based mostly on how issues stand at the moment, whereas a lot concerning the finish of the century stays unknown. What’s going to occur to the agricultural and power sectors? And to river natural world, since rising temperatures hinder replica and improve the chance of illness in fish? How will we guarantee enough electrical energy manufacturing if discharge decreases drastically? And if Switzerland decides to construct new nuclear energy or different industrial vegetation, how will we preserve them cool?

The necessity to act now

Fairly than tackling questions concerning the future, Michel is looking for motion now: “Our research of river discharge and temperatures reveals, for one, that the affect of worldwide warming is inevitable, and that we should start making adjustments at the moment, by power and agriculture insurance policies, for instance. It is also exhibiting us that we will nonetheless save part of our environmental heritage — however provided that we act swiftly and aggressively.”
