Hoverboards can catch fire, cause spinal injuries, ACCC warns

The Australian Competition and Customer Commission (ACCC) has issued a warning more than hoverboards, saying faulty style has caused fires overseas, and that users could be injured by way of falls.

In spite of their name, hoverboards, which retail for amongst $ 200 and $ two,400 according to the ACCC, are two-wheeled electrical scooters.

Also identified as self-balancing scooters and referred to by one particular manufacturer as “hands free of charge Segways”, they are controlled by subtle shifts in the rider’s weight.

Many reports from America and Britain have detailed hoverboards catching fire although being ridden or while charging.

This week, the Chappaqua Fire Department in New York released photos of a hoverboard that caught fire although being charged, causing “considerable smoke damage to the residence”.

“Had the property owners not been property at the time, their home would have sustained important fire harm,” the department said, warning electronic devices should only be charged while someone is at home.

The ACCC stated reported fires “most most likely relate to items that would not comply with Australian electrical requirements, or to the use of a charger meant for an additional device”.

“If you are acquiring a hoverboard this Christmas, make certain that the packaging is marked with the Australian regulatory compliance symbol or RCM — a tick surrounded by a triangle,” ACCC deputy chairwoman Delia Rickard said in a press release.

“Overcharging noncompliant devices could trigger overheating of the battery and result in a fire.”

Ms Rickard warned owners to constantly use the approved battery charger that came with the solution, and to in no way charge a hoverboard that shows signs of harm near the battery.

Last week, Decision Australia released a warning to owners to make certain they did not overcharge the units, noting some hoverboards carried warnings about overcharging in their manuals.

Flight Security Australia, the news internet site of the Australian Civil Aviation Authority, reports airlines are reviewing their policies on carrying hoverboards.

The International Air Transport Association is recommending “operators restrict these devices to carry-on luggage,” Flight Security Australia said.

The ACCC also warned falls from hoverboards are hugely likely.

“Injuries could include fractures, sprains, cuts, bruising, spinal injuries, head injuries and concussion,” the agency stated.

The ACCC said suitable security equipment, including shoes, a helmet, knee and elbow pads, and wrist guards, should be worn at all instances.

The legality of making use of hoverboards in public locations varies among states and territories.

Option said hoverboards have been only allowed on paths or public land in Queensland, the Northern Territory and Tasmania.

The ACC urged riders to verify with neighborhood site visitors authorities or police just before riding in a public spot.

Which way’s up? Figuring out how our spinal cord ended up on our back

Our left and correct sides are largely mirror images of every other. That makes us bilaterians, a massive group of animals that range from tiny flies to giant whales. But we and the whales share a significant difference with flies—where we place our nerve cord. For us, the spinal cord runs down on our back. For flies and other insects, the principal nerve cord is on the underside of the animal.

This would not be that surprising if the two nerve cords had distinct origins, but we’ve found that all the molecules that spot and pattern the nerve cord are related in insects and vertebrates. That suggests the nerve cord has constantly been in the exact same location rather, the rest of the body somehow ended up flipped relative to the nerves. Now, the genome of a strange animal called the acorn worm may support us sort out how that could have happened.

One feasible hypothesis for how the nerve cord flipped is that the ancestor of us vertebrates lived as a burrowing animal in a marine environment. There, such an ancestor might not want any prime/bottom axis and could have lost it. Once its descendants re-emerged from the mud, they re-established this axis but did it in the opposite orientation.
